2019 Toyota Sienna problems
The Toyota Sienna is a minivan manufactured and marketed by Toyota primarily for the North American market. It is named for the Italian city of Siena, in the region of Tuscany. It replaced the first generation Previa van in 1997 with a more conventional front-wheel drive layout and shares a heavily revised platform with the Camry. Both the Previa and original Sienna were smaller than the other minivans they competed against, but a redesign in 2003 (for the 2004 model year) increased the dimensions to match those of its competitors.
It was redesigned again in 2010 (for the 2011 model year). The third generation Sienna went on sale in the United States in February 2010 and is the first Sienna to ever receive a "Top Safety Pick" award from the Insurance Institute for Highway Safety. A 2020 redesign (for the 2021 model year) saw the Sienna becoming a hybrid vehicle for its fourth generation. While previous generations of the Sienna were exported to select Asian and European markets, the fourth generation is the first to be produced outside of the United States as Chinese production commenced in July 2021 by two Toyota joint ventures. In China, it is also marketed as the Toyota Granvia.
Following the discontinuation of General Motors's all-wheel drive minivans in 2006, the Sienna was the only minivan in its class offered with AWD in North America until the 2021 Chrysler Pacifica was introduced with an AWD option in 2020.
The Sienna is not available in Japan and Australia as it is not produced in a right-hand drive configuration, and the segment in these countries is already occupied by the Alphard/Vellfire and the HiAce/Granvia respectively.
As of the fourth generation, introduced in 2020, the Sienna is now built on Toyota's TNGA-K platform, which it shares with most of Toyota’s other large MPVs and crossovers.

AIR BAGS PROBLEM
- Date Of Incident: 2023-09-14
- Crash: 1
- VIN: 5TDYZ3DC7KS
- Components: AIR BAGS
- Summary: My van was struck directly in the driver side rear sliding door while sitting still at a stop sign. The other driver collided straight into the passenger compartment door at an approximate speed of 30 mph crushing the door, exploding the window and neither the driver side airbags nor the side curtain airbags deployed. Resulting in my wife severely jarring around in the driver's seat, as well as my son who was securely fastened in a child booster seat in the driver side rear seat. The glass from the rear door window shattered and covered my son and the interior of the vehicle. There are no active recalls, but I read about a recall concerning the passenger side door welds that could affect operation of the side airbag and side curtain airbag sensors, but this only applied to a small number of 2019 Sienna's. Could this have been a manufacturing defect that bled over to the other door structures affecting the sensors in the same way.
POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM PROBLEM
- Date Of Incident: 2019-10-17
- VIN: 5TDKZ3DC3KS
- Components: POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM
- Summary: Car was recalled for fuel pump and I repaired in 8/2020 with approximately 11,190 miles. I had complained that car, since time of purchase and had 4662 miles when I insisted Toyota fix this, (hunted for gears, hesitated, lagged when accelerator pushed, and had poorer gas mileage than expected). The car now has 34,875 miles on it and is doing the same thing, hesitating, lunging between gears. Our mechanic confirmed this and stated worse when using a.c. Called Toyota Customer Service and they said the car was out of warranty for the pump repair, but perhaps not the power train, transmission, etc. Have not gotten back to me yet, but has not been one working day after spending 2.5 hours on the phone with them yesterday. This is a safety issue, I press on the gas to make a turn and it lags leaving me in traffic. My 2007 Sienna, which is still running for my daughter, never did this and has full power when called upon. Toyota needs to repair the entire fuel system, transmission, if they cannot fix this. There are no warning lights when this happens & it is happening more frequently. Dealership told me they could not put another pump on car and to contact Toyota Customer Service and gave me the number. When we had the car for about a month, dealership said we were just not used to driving a car with this type of transmission and car was low on oil, we added oil and dealership said we used the wrong type, but we figured some oil was better than no oil. We are boomers and have been driving cars for decades, with clutches and without and we know how to drive a vehicle.
VEHICLE SPEED CONTROL PROBLEM
- Date Of Incident: 2023-05-10
- VIN: 5TDKZ3DC1KS
- Components: VEHICLE SPEED CONTROL
- Summary: The contact owns a 2019 Toyota Sienna. The contact stated that after he entered the vehicle, he depressed the brake pedal to start the vehicle. After the vehicle was started, he shifted into reverse(R) while the brake pedal remained depressed; however, the vehicle inadvertently accelerated without warning. In a desperate attempt to stop the vehicle from crashing into another vehicle, the contact shifted into drive(D) while the brake pedal remained depressed. The contact then stated that he applied pressure to the brake pedal to stop the vehicle from accelerating when the vehicle then jumped the curb and struck a garbage can. The contact then shifted into reverse(R) while the vehicle continued to accelerate to move away from the garbage can and then shifted in neutral(N). The contact then shifted back into park(P). The contact then stated that after he placed the vehicle in park, the inadvertent acceleration stopped. The contact shifted into drive(D) and the vehicle performed as designed; however, the contact was concerned for his safety and carefully drove the vehicle to his residence where the vehicle remained. The contact was unsure if any warning lights were illuminated. The vehicle was not diagnosed or repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 45,750.
UNKNOWN OR OTHER PROBLEM
- Date Of Incident: 2022-12-12
- VIN: 5TDJZ3DC3KS
- Components: UNKNOWN OR OTHER
- Summary: Problems with catalyst
ELECTRICAL SYSTEM,UNKNOWN OR OTHER PROBLEM
- Date Of Incident: 2022-11-15
- VIN: 5TDYZ3DC9KS
- Components: ELECTRICAL SYSTEM,UNKNOWN OR OTHER
- Summary: The microphone has an issue and it is tied to the SOS call button in the car. I asked my dealership, they wanted to charge $200 to run a diagnostic scan, I contacted Toyota directly, they basically said the dealer can charge it if they want and reverse the charge if they find a problem under warranty. I originally thought the issue was with the Blue Tooth. I found this video on YouTube, his fix did work-my concern is, if I had needed Emergency help-the button would not have called anyone, disconnecting your car battery is NOT something I should I have to do to fix a 2019 vehicle. https://www.youtube.com/watch?v=FkAdMRKHS_0
POWER TRAIN PROBLEM
- Date Of Incident: 2022-12-14
- VIN: 5TDYZ3DC3KS
- Components: POWER TRAIN
- Summary: I was traveling on the Capital Beltway (495) during morning rush-hour in my 2019 Toyota Sienna Minivan. Normal Road Conditions: Stop & Go traffic in the right-most lane around 9:30am on December 14, 2022. All of a sudden and without warning, when attempting to accelerate and keep up with traffic after the vehicle was stopped, I found that I was unable to move forward. (There was no indication that my vehicle was suffering from mechanical failure prior to this incident and no visible alert or alarm was triggered) At that point, I powered down the vehicle after turning on the hazard indicator lights. After re-engaging the ignition, I then tried to move forward, and found the vehicle to be unresponsive. A tractor trailer was directly in back of me and was inching closer as to keep up with the rush-hour traffic. I was immovable at that moment and waived the truck around. After finding a break in traffic, I attempted to move out of the right-most lane, but with the transmission not responding to the Drive function, found that my only course of action was to to engage Reverse and move to the Right shoulder of the highway. I then notified triple A and my vehicle was towed to a local garage for evaluation. Upon initial evaluation is was determined that it was either related to where the shift cable goes in to the transmission, or complete transmission failure. It is highly unusual for a Toyota transmission to fail at 71.000 miles (odometer reading at the time of the incident). I currently have two other Toyota vehicles with odometer reading in excess of 140,000 miles. I am concerned for the safety of my family and myself, as this is the primary vehicle used for transport. A 3 year old car with less than 100,000 miles should not suffer from transmission failure. This is a major safety concern. What if this happened and I was not in stop and go traffic or already in the slow lane, on a major highway?

The vehicle was not diagnosed or repaired. The contact stated that she noticed the mirrors were fractured. While driving at an undisclosed speed, several unknown safety features became inoperable. There was a burning odor detected inside the vehicle. The manufacturer was contacted and offered to pay a nominal portion of the repair for the mirrors and referred her to the NHTSA Hotline for assistance. The approximate failure mileage was 72,000.

- Summary: This tire separated at the side wall nearest the rim. The last one separated and swelled roughly the size of a ping pong ball, prior to that the same thing. This is the 3rd Pirelli Scorpion Verde All Season tire to fail. After this last one, I realized it's got to be something with the construction of the tire so I googled and found recalls for other Pireeli tire models. I contacted the mfr and they refused to assist. Spoke with very rude individual at Pirelli USA in Rome, GA location who stated 'if I am concerned about the safety of the tire, report it to the NHTSA' and that in order to obtain a replacement I would have to contact the retailer to initiate a return. As instructed, I spoke with the retailer Simple Tire (Trevose, PA), an individual named Shailesh. I was told since there is no NHTSA recall therefore there is no replacement.
EXTERIOR LIGHTING PROBLEM
- Date Of Incident: 2022-05-01
- VIN: 5TDYZ3DC0KS
- Components: EXTERIOR LIGHTING
- Summary: The headlight on the passenger side has LED daylight running lights. A number of the led's are not working of flickering. Toyota refuse to cover this under warranty even though the car was bought 8-31-2019. Not having working daytime headlights is a major safety issue to me.

- VIN: 5TDDZ3DC6KS
- Components: VISIBILITY
- Summary: The contact called on behalf of her husband who owns a 2019 Toyota Sienna. The contact stated while her husband was driving approximately 65 MPH, there was an abnormally loud bang heard. The driver became aware that the sunroof glass had shattered and that a part of the glass was missing. The driver continued to his destination. The vehicle was not diagnosed; however, the contact spoke with the local dealer; who informed him that a foreign object probably had struck the sunroof for the glass to shatter. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 30,000.
UNKNOWN OR OTHER PROBLEM
- Date Of Incident: 2022-05-02
- Number Of Injuries: 1
- VIN: 5TDJZ3DC2KS
- Components: UNKNOWN OR OTHER
- Summary: The power sliding door on the driver’s side of the vehicle is malfunctioning. When the door is opened with the electric opening function, it detects resistance and starts to close. While closing, the door closes with great force and no longer attempts to detect closing resistance. Me, my wife, and my infant daughter have been crushed/trapped by the door. My daughter had her arm trapped in the door. My wife had her back crushed. The Toyota dealer in Tucson, AZ (Precision Toyota) said the electrical cables inside the door are binding, causing the resistance when opening. We have not modified or otherwise touched the electrical door opening cables during our three years of ownership and therefore believe this is an engineering design flaw, or manufacturing defect. My concern is that there may be several other doors with this defect which could eventually lead to great harm on a young child, in the form of a crushing injury.

- Components: AIR BAGS
- Summary: I own a 2019 Toyota Sienna with 52,200 kms. I bought it January 29, 2021. On Saturday, June 26, 2021, I was exiting the Quebec to Lévis ferry on the Lévis side. As I went up the metal ramp at 10-12 km/hr, ALL the airbags suddenly deployed with a great boom. We hit nothing. ALL The front and side airbags deployed. The front windshield was broken and one of the side windows was totally shattered. In fact it was not there any more. Pieces of broken glass flew all over the car and hit us. The vehicle filled up with smoke. On board was my wife and I and our two special needs sons. We had to hurriedly get them unstrapped and hand them to ferry workers on the outside. I was the only one injured. I received the airbag straight in my face and it hurt my neck. I have had a headache and neck ache ever since (today is June 29). I ignore the reason for which the airbags deployed. But I do know that Toyota has had to recall other 2019 Siennas for spontaneous deployment of their airbags. Maybe it is an airbag defect. My vehicle was still under warranty. The fire department and police were on the scene. The Levis Ferry director wrote a report. The Levis police report is LVS-210626-008. Thank you.

We bought this to replace our 1998 Sienna, which we had bought new. We waited until the 2018 model to get the safety features in Toyota Sense. The Sienna is easy to drive and has enough cargo room that you can fit two recumbent trikes in the back. The safety features have been great, making backing out of a parking space or parallel parking so much easier than before.

My 2005 AWD Sienna was my perfect companion. It provided me with comfort, reliability, and performance. The interior was well-planned and executed, and it had every feature I could possibly need, from electric doors to a tachometer to opening vents to remote start. Despite its size, the steering was responsive, acceleration was quick, and braking was surprisingly good, even when loaded with cargo. Maintenance was minimal, involving only replacing brake pads, one timing belt, buying tires, and performing required oil and transmission fluid changes. The 2018 AWD Sienna has a lot to live up to, and in many ways, it meets or exceeds its predecessor. The acceleration is smooth and quick, and the brakes are outstanding. It has a bit more cargo space than the 2005, and all of the sliding doors open with ease. The abundance of electronics on the 2018 is both impressive and a bit intimidating, but features like the 360-degree camera are quickly becoming necessities.I really miss the remote start, especially after snow storms when it could be a lifesaver. It would soften the ice and snow, making it easier to clean off the van. Despite this, I appreciate that the Toyota engineers have remained loyal to Sienna enthusiasts like myself. However, I do wish that the interior design team had done the same. Even though I have a top of the line model, the materials used feel cheap and the details that I loved have been removed. The third row stowage system is particularly frustrating. As someone who is not small and has long arms, I find it difficult to reach the stowage handle, which replaced one of the fabric tabs. Did anyone test this design with someone of a different size or shape? Toyota, please bring back the 2-section front console! The new unit between the front seats is like a black hole where nothing can be found, especially while driving. I also miss the front in-door armrest storage compartments, which were perfect for holding items needed at a moment's notice. The front seat passengers are down one cup holder from earlier interior configurations. I am concerned about the durability of the pop-out pair of cup holders and the I hope this message finds you well. I wanted to share some feedback on the rear window wiper of the Sienna. I noticed during the snowy season that the wiper design could be improved. It no longer provides a full 180 degree sweep centered on the bottom of the window. Instead, it sweeps from the top of the window and makes an asymmetric sweep of about 100 degrees, leaving almost a third of the window uncleared. If you're considering purchasing a Sienna, I would highly recommend ensuring it has the blind spot detectors. The view out the rear window can be obstructed in bad weather, and those detectors can make a big difference. Thank you for your time and consideration.

We recently purchased our 2nd Sienna Van, the 2018 model. While it is a good solid van, we miss the nooks and crannies our 2010 model had for storage. The lack of door armrests that lifted up for storage within and a smaller console for nick nacks is a big drawback. Additionally, there are no extra storage spaces like that, and no extra storage under the 3rd row seats when the seats are in the down position. The driver's vent can't be positioned directly on you, and the turning radius is even better than our previous van. Although the rear window is a bit smaller, we bought one of those panoramic rearview mirrors to help see what is around us, which helps a lot. The new safety features are a big plus. We are not fans of the black carpet, so we ended up removing the black floor mats and replaced them with grey rubber mats (Weathertech) that hide the dirt better and are easier to clean. The heated front seats are a nice touch, but the supposed heated steering wheel doesn't hardly get warm. All-in-all, we are pleased with our 2018 Sienna Limited Premium. Toyota makes great cars, but there is always room for improvement. We have been buying Toyota's for 45 years and sure do wish the Hybrid was available when we bought this one. It's sad that they were available the year after our purchase. By the way, when we drove off the lot with this van, we didn't notice it was missing the roof rail crossbars.We spoke to the dealer about our concerns. It was disappointing to find out that the crossbars were not included in the Toyota Sienna Limited Premium, especially considering its high price of almost $50,000. However, we had a friendly and productive conversation with the manager of the dealership's Internet Sales. She kindly agreed to add the roof crossbars at no extra cost. While we had a few other minor complaints, such as the positioning of the front seat headrests and the lack of a hook for a trash container, overall we are satisfied with our purchase. Thank you to the dealership for their understanding and willingness to address our concerns.

I am writing this review 3 months and 3500 miles into owning a 2018 Sienna XLE. I am very impressed with the safety features. In fact, the automatic assist braking helped save me from an accident when the vehicle in front of me came to a sudden stop on the highway because they missed their exit! The radar proximity alarm sounded and brakes were applied before I realized that the car in front of me was coming to a complete stop, without any cars in front of it. I have received lots of compliments on the comfort of the interior, especially the seats. I live in Florida, but ended up buying the car in Virginia, because apparently Toyota is separated into three regions: Southeast, Gulf Coast, and everything else. The Sienna was about $3k less in Virginia than in FL. It was well worth the drive! I do wish Toyota would have rounded dials for the air conditioner, similar to an iPod, rather than push buttons. You have to look down each time to adjust the buttons. If you had a dial, you could spin it without having to look down. I am not a fan of Toyota's Ensuite. I wish I could have bought the car without it. However, overall I am very happy with the purchase, especially considering the great price I got for it. The Odyssey was its biggest competition, but the 2018 Sienna seemed like a better value; and I can confidently say that I made the right decision.

This van does exactly what it should and nothing more. It could benefit from some exterior lighting updates, such as LED lights, and additional Limited level features like an individual tire pressure display for TPMS. It would also be great to have programmable side view mirrors that open at engine start and close at engine stop, as well as a factory option for a 2” receiver trailer hitch and wiring. In my experience, a couple of extra inches of floor-to-ceiling height in the second and third rows (and rear rear hatch opening) would make this van much more versatile for transporting bikes and larger items.

Are you having problems with your 2019 Toyota Sienna?

I have owned a 2009 Sienna LE, a 2012 Sienna XLE, and now a 2019 Sienna XLE Premium. I am happy to report that my first two cars lasted over 100,000 miles with only routine maintenance. I have only owned my 2019 Sienna for 4 days, but I am already impressed! Although I am still trying to figure out some of the features, I am confident that I will get the hang of it soon. As a 78-year-old, I find that my learning is a little slower than it was a few years ago. I have also owned a 2006 Corolla and currently own a 2012 Camry LE, and I have not been disappointed in any Toyota vehicle. UPDATE 5/11/2020: I reported some major issues with the Navigation System to Toyota over a year ago, but unfortunately, they have not been able to fix the problem. I spent an extra $2000 to get the Navigation System, and I believe that Toyota should refund some of that money, but they have not done so. As a result, I have had to resort to using my Garmin GPS, which is more reliable. However, all other aspects of the Sienna are very satisfactory. I recently traded it for a 2021 Sienna, and I absolutely love it!

The Sienna is a great family car that offers excellent value. It has plenty of space and is easy to get in and out of. We have owned two Siennas, starting with the base model and then upgrading to the limited. The limited model has some really nice features, such as a back-up camera, parking assistance/warning system, keyless door entry, heated seats, and a great sound system. However, we have had some issues with Toyota's service department at Stapp Interstate Toyota in Northern Colorado. They have been dismissive and unresponsive, which has been frustrating. Additionally, we have experienced an issue with both side view mirrors clicking/jostling when accelerating or decelerating. This is distracting and started within a year of owning a brand new car. Despite bringing this issue to the attention of Toyota's customer care team and management, they have not been helpful in resolving the issue. While we have had some negative experiences with Toyota, I would still recommend the Sienna as a good family car for its space and storage. It is worth noting that the road noise is high due to the car's size, and there is some wind noise from the moon roof, but this is to be expected. Overall, the Sienna is a great choice for families in need of a spacious and reliable vehicle.

Living on 1.5 miles of gravel, we opted for the AWD Sienna. Unfortunately, we've experienced multiple tire balance issues within the first year of owning it. According to the dealership, rocks and mud can get stuck between the wheel and hub, causing balance issues. To fix this, the wheels need to be taken off and cleaned. Despite having to deal with this issue multiple times, we still appreciate the Sienna's performance in wet conditions. However, we do not recommend it for those who frequently travel on gravel roads. It's been great for winter driving, especially in town, but we haven't tested it in drifting conditions. When it's windy, we prefer to drive our pickup instead.

We recently upgraded from a 2008 to a 2018 model, hoping for a better experience. Unfortunately, we have found that the only improvement is the birds eye camera. Our family has unanimously expressed their dislike for the car, and we now prefer to use my Grand Cherokee for all our trips except skiing. The cabin is quite spacious, but unfortunately, the sliding seats make it difficult to fit rear floor mats, and the black interior is already showing signs of wear and tear after just 8 months of use. Additionally, the car's fuel efficiency has decreased from 13.8mpg in the '08 model to 10.7mpg combined. The multimedia system is poorly designed and lacks features, and the GPS is unchanged from the previous version. The V6 engine is underpowered, and the car handles like a boat. Most of the discrete storage has been removed, leaving only a single, enormous console compartment to store everything. The only redeeming quality of this van is the AWD system. However, after just 8 months, my wife and I both agree that we should have purchased a second Grand Cherokee instead, which is plenty big for our family of four, handles well, and gets 17mpg combined. Overall, we are quite disappointed with our purchase.

I absolutely adore Toyotas, and this is actually my second Sienna! My first one was a 2007 model, which I loved, but it had a lot of miles on it. When I purchased the 2018 model, I was over the moon with happiness driving it off the lot. My husband also has a 2017 Rav4, which we both love! Unfortunately, I did experience some issues with my Sienna. When I slowed down to make a turn and then accelerated, I experienced a dangerous hesitation with a whip-lash effect. At first, the dealership didn't have any answers as to what was causing the problem, but now I have been informed that it is due to the throttle by wire design in the vehicle and the vehicle trying to select the proper gear when you go full throttle from stop or driving down the road. This is a serious issue when you don't have control of your accelerator! I also noticed that I have to keep the key turned much longer than I have ever had to with any other vehicle that I have owned. The dealership says that this is normal. The MPG was anywhere from 15-16, but bumped up to 18 during the summer when the gas changed. On a long highway trip, I did go over 23 MPG, but my old Sienna did much better. I have also had some issues with the Scout GPS, as it doesn't show a picture of the road, just arrows, and it's not very reliable either. The sliding doors also squeal frequently, and when I take it into the dealership to be greased, it comes back with paperwork showing that the problem could not be duplicated, but the doors still squeal. There are also times when my passenger front seat airbag indicator is not working properly when I have a passenger, and it shows that the airbag is not on. I have had this checked several times. Lastly, the center dash screen dims at times when the headlights go on when it is raining during the day, and I can't see what is showing on the screen. It was repaired once, but it reverted back to it recently after a recent download of some sort. Now the customer service man said that there is no such setting to adjust. I had to go find my old paperwork and now will have to go and call and have him look up to show him that I am not making things up.When they had to do the recent download, they told me it took the shop guy 8 tries to get the download to work. If this vehicle weren't under warranty, I can only imagine what that bill would have been! And I have never been in the Toyota dealership with a vehicle as much as I have been with this 2018 Sienna!
