The Toyota Prius Plug-in Hybrid (often abbreviated as the Prius PHV and known as the Prius Prime in North America, South Korea, and New Zealand) is a plug-in hybrid liftback manufactured by Toyota. The first-generation model was produced from 2012 to 2016. The second-generation model has been produced since 2016. Production of the third-generation model began in 2023.

The Prius Plug-in Hybrid was the second most sold plug-in electric car in 2012, and became third-best all-time in December 2014. As sales declined after the end of its production, the Prius PHV fell to fifth place in the global ranking by November 2015, after being surpassed by both the Tesla Model S and the Mitsubishi Outlander PHEV. As of December 2017, sales were led by North America with 66,800 units, followed by Japan with 48,800, and the European market with 13,100 units. The U.S. was the leading country market with 65,703 units sold by 2017. As of December 2019, cumulative global sales of both Prius plug-in generations totaled 209,000 units.

Concept and demonstration models

The Prius Plug-In Hybrid Concept was exhibited at the September 2009 Frankfurt Motor Show, the October 2009 Tokyo Motor Show, and the December 2009 Los Angeles Auto Show. The vehicle was based on the third-generation Toyota Prius (model XW30) but outfitted with 5.2 kWh lithium-ion batteries. The selected battery capacity is the minimum required for a vehicle to be eligible for the U.S. federal tax credit of US$2,500, which under the American Clean Energy and Security Act of 2009 is applicable to the first 200,000 plug-ins sold by an automaker.

After displaying the concept version in these three shows, a global demonstration program involving 600 pre-production test cars began in late 2009 and took place in Australia, Canada, China, France, Germany, Japan, New Zealand and the United States. The demonstration vehicles were made available for lease to fleet and government customers, of which, 230 were delivered in Japan beginning in late December 2009, 125 in the U.S. by early 2010, and 200 in Europe in spring 2010. All program vehicles were equipped with data tracking devices to allow Toyota to monitor the car's usage for further development of the plug-in hybrid system.

The pre-production Prius Plug-in used three different batteries: two added batteries to provide all-electric drive and the standard hybrid battery which engages when the first two are depleted, allowing the car to operate like a regular hybrid Prius. According to Toyota, when the vehicle started, it operates in all-electric mode, drawing electrical power directly from the first battery pack. When the first battery was depleted, it disconnected from the circuit and the second pack engaged. When the second pack was depleted, it disconnected from the circuit and the vehicle defaulted to conventional hybrid mode, using the main battery as the sole electrical power source. Pack one and pack two would not reengage with the circuit until the vehicle was plugged in and charged.

According to Toyota, the demonstrator was rated at 1.76 L/100 km (134 mpg‑US; 161 mpg‑imp) on the Japanese JC08 cycle with a combined efficiency based on 43.6% of driving in EV mode, and CO2 emissions of 41 g/km. Fuel efficiency operating as a gasoline-electric hybrid, like the regular Prius, is 3.3 L/100 km (72 mpg‑US; 86 mpg‑imp) with CO2 emissions of 76 g/km.

Common 2018 Toyota Prius prime problems

The 2018 Toyota Prius Prime has been reported to have several common problems based on complaints from owners. Here are the details of those problems:

Electrical Accessories Issues: Some owners have reported issues with electrical accessories, including the infotainment system, rear entertainment system, backup or other camera/sensors, head-up display, and microSD card for the GPS. The microSD card for the GPS was removed to show to the Toyota parts manager. When it came to time to reinstall the card, the car would not recognize the card. Toyota Service requests I have them troubleshoot the problem and I have not done this. The cost of keeping the GPS maps current is expensive and replacement of the microSD card is awkward and unreliable.

Paint and Trim Issues: Some owners have reported issues with paint and trim, including cracked windshield that had to be replaced.

EV Battery Issues: Some owners have reported issues with the EV battery, including starter battery needed to be jumped on a couple of occasions.

In-car Electronics Issues: Some owners have reported issues with in-car electronics, including infotainment system (audio, GPS, phone), rear entertainment system, backup or other camera/sensors, head-up display. The microSD card for the GPS was removed to show to the Toyota parts manager. When it came to time to reinstall the card, the car would not recognize the card. Toyota Service requests I have them troubleshoot the problem and I have not done this. The cost of keeping the GPS maps current is expensive and replacement of the microSD card is awkward and unreliable.

Windshield Cracks: Some owners have reported issues with the windshield, including windshield cracked in the 2019 Prius Prime, windshield cracks easily in the 2018 Prius Prime, and windshield chips and cracks easily in the 2017 Prius Prime.

Rodent Damage: Some owners have reported issues with wires chewed by rodents in the 2017 Prius Prime.

AIR BAGS PROBLEM

Date Of Incident: 2023-08-03
Number Of Injuries: 2
Crash: 1
VIN: JTDKARFPXJ3
Components: AIR BAGS
Summary: Airbags deployed prematurely as I was parking my car in a doctor's office parking lot. The car was going less than 5 mph and I did not hit anything. The premature deployment of the airbag startled me and caused me to hit the accelerator instead of the brake and I ended up crashing my car into a nearby pole and another .automobile. The accident resulted in a soft tissue injury for my daughter and I'm experiencing lower back pains. The air bag caused burns on my nose and arms. My daughter has bruising on the arms from the air bag deployment

POWER TRAIN PROBLEM

Date Of Incident: 2023-04-14
VIN: JTDKARFP3J3
Components: POWER TRAIN
Summary: Take foot of break, car accelerates under power. Sooner or later, this is going to result in killing a pedestrian. The question has been for the last year, is this a behavior that can be gotten used to. The answer is definitely NO! This resulted in a near collision with a pedestrian today. Toyota believes the behavior is intentional and will not confirm the safety issue. Farmers Insurance is willing to believe the issue exists without inspection but has no idea what to do. You have a problem on your hands. Biden is trying to transition almost everybody away from gasoline vehicles; thus those that drive manual transmissions will be driving electric vehicles, and their brain patterns have not changed and the procedure for getting rolling from a dead stop will be done the old way, and it's now dangerous. In a manual transmission it is necessary to transition off the break before completing looking all three ways (left, right, straight) because the transition time from break to power is so long that if the looking is done before, it is out of date by the time power is being applied. Applying the same procedure to an electric car has potentially lethal results; and people who have been driving a manual transmission for a long time will end up using its procedure in an electric car by habit. Perhaps you observed the reports over the last few decades of old men with new cars having unintended acceleration problems with no cause found. I now believe that a number of these have a very similar explanation. Car isn't off, take foot of break to get out of car, car accelerates. In an electric car, telling the car isn't off isn't very easy any more. This is easy to understand. An automatic transmission vehicle has an unremovable dumb behavior where take foot off break accelerates, whereas in a manual transmission this stalls, which is a safer result. There is no reason this behavior should carry over to computer drive, including electric or hybrid vehicles.

BACK OVER PREVENTION,FORWARD COLLISION AVOIDANCE PROBLEM

Date Of Incident: 2018-11-15
VIN: JTDKARFP0J3
Components: BACK OVER PREVENTION,FORWARD COLLISION AVOIDANCE
Summary: From the first week of ownership sensors would alarm that they needed cleaning but they were clean. Parking assist sensors also malfunctioning. Also saw Intelligent Clearance Sonar error messages and warnings. Alarm tended to go off in wet weather. Brought to dealership many times and problem occurred infrequently that no problem was ever found. For two years I was plagued by alarms of sensor malfunction. I worried the sensors would fail to detect cars and objects in front of, behind or on the side of the car. That would be a serious failure and cause of an accident. After two years of unsuccessful testing, I traded in the car.

EXTERIOR LIGHTING PROBLEM

Date Of Incident: 2021-01-28
VIN: JTDKARFP4J3
Components: EXTERIOR LIGHTING
Summary: WHILE DRIVING ON RURAL ROADS WITH NO STREET LIGHTS, THE AUTOMATIC HIGH BEAM SYSTEM MALFUNCTIONS WHEN PASSING ONCOMING TRAFFIC WHO DO NOT DIM THEIR HEADLIGHTS OR WHO HAVE THOSE HEADLIGHTS THAT SHOULD BE ILLEGAL (LIKE FORD). NORMAL LOW-BEAM HEADLIGHTS DO NOT CAUSE THE SYSTEM TO MALFUNCTION. I BELIEVE THIS MALFUNCTION TO BE RELATED TO THE CAMERA SENSOR LOCATED ON THE WINDSHIELD AND WHEN THE GLARE OF THE EXCESSIVELY BRIGHT HEADLIGHTS HIT THAT SENSOR, IT CRASHES THE AUTO SYSTEM. THE SYMBOL ON THE DASH THAT INDICATES THAT THE SYSTEM IS WORKING NORMAL CUTS OFF FOR APPROXIMATELY 25-30 SECONDS, DURING WHICH TIME THE HIGH BEAMS WILL NOT ENGAGE. AFTER THAT 30 SECOND DELAY, THE SYSTEM REBOOTS, THE LIGHT ON THE DASH COMES BACK ON AND THE HIGH BEAMS RE-ENGAGE. THIS IS DANGEROUS AS ALL MANNER OF WILDLIFE CROSS THAT ROAD AT NIGHT AND WITHOUT BRIGHT LIGHTS, MY REACTION TIME IS CUT IN HALF. I HAVE TALKED TO THE TOYOTA DEALERSHIP ABOUT THIS ISSUE SINCE I PURCHASED THIS CAR IN MAY OF 2019 TELLING THEM THERE IS A MALFUNCTION IN THE SYSTEM, AND WAS INITIALLY INFORMED THAT THIS WAS NORMAL FUNCTIONALITY. I OWNED A 2017 PRIUS PRIME ADVANCED (ONE YEAR OLDER THAN THIS ONE) AND IT NEVER MALFUNCTIONED, SO I KNOW THIS IS A MALFUNCTION IN THE SYSTEM. AFTER SPEAKING WITH THE SERVICE MANAGER IN DEPTH ABOUT MY EXPERIENCE WITH THIS ISSUE, HE FINALLY UNDERSTOOD THAT THIS IS AN ISSUE AND NOT NORMAL FUNCTIONALITY. THEY HAVE KEPT MY CAR SEVERAL TIMES TRYING TO RECREATE THE FAILURE, BUT UNLESS THEY DRIVE OUT IN THE MIDDLE OF NOWHERE (SUPER DARK) AND COME ACROSS SOMEONE WITH "TOO-BRIGHT" HEADLIGHTS, IT IS UNLIKELY THEY WILL ACCOMPLISH A FAILURE. I WAS ALSO TOLD THAT TOYOTA DID NOT KNOW ANYTHING ABOUT THIS ISSUE. I HAVE SINCE DONE THE RESEARCH AND FOUND THAT THIS HAS BEEN AN ISSUE SINCE AT LEAST 2017, AND OCCURS ON VARIOUS TOYOTA MODELS (PRIUS, AVALON, RAV4, ETC...). I HAVE VIDEO OF THE FAILURE.

ENGINE PROBLEM

Date Of Incident: 2020-12-01
VIN: JTDKARFPXJ3
Components: ENGINE
Summary: AFTER THE HYBRID BATTERY IS DISCHARGED, AND THE GAS ENGINE KICKS IN, THE VEHICLE LOSES POWER FOR APPROXIMATELY 5-10 SECONDS ON THE FREEWAY. THIS HAS HAPPENED FOUR TIMES, AT APPROXIMATELY 7 AM, ON DECEMBER 1, 10, 14 AND 15. ON ALL OCCASIONS, THE TEMPERATURE WAS BETWEEN 40-45 DEGREES FAHRENHEIT, AND AT HIGHWAY SPEEDS. THE CRUISE CONTROL WAS NOT IN USE. NO WARNING LIGHTS CAME ON. I CALLED THE TOYOTA DEALER ON DECEMBER 1 AND THE SERVICE ADVISER SAID THAT SINCE NO WARNING LIGHTS CAME ON, HE COULD NOT DETERMINE THE PROBLEM. I HAVE A PHOTO SHOWING MY CONTACTING THE TOYOTA DEALER ON DECEMBER 1ST. ON DECEMBER 10, I TOOK THE VEHICLE INTO TOYOTA IN THE AFTERNOON. THE DEALER CHECKED THE VEHICLE AND ROAD TESTED THE VEHICLE WITHOUT HAVING THE HYBRID BATTERY CHARGED, AND THE AIR TEMPERATURE WAS WARMER. I WAS CHARGED $210 FOR THE DIAGNOSTIC SERVICE, ALTHOUGH I HAVE AN EXTENDED WARRANTY. THE SAME PROBLEM OCCURRED ON DECEMBER 14 AND 15. SPECIFIC PROBLEM UNKNOWN BUT I BELIEVE THAT A SWITCH THAT CONTROLS THE GASOLINE VOLUME INTO THE ENGINE AFTER THE HYBRID BATTERY POWER IS DEPLETED IS DEFECTIVE. I WAS IN THE CARPOOL LANE AT APPROXIMATELY 7 AM ON ALL 4 OCCASIONS AND MY SPEED DROPPED, ALTHOUGH I DEPRESSED THE GAS PEDAL TO MAXIMUM AS WELL AS PUMPING THE GAS PEDAL, ALL TO NO AVAIL. THE CAR IS IN USE ONLY MONDAY, TUESDAY, WEDNESDAY AND THURSDAY, THE DAYS THAT I WORK. I CONTACTED TOYOTA CUSTOMER ADVOCATE (800-331-4331, CASE # 2012120505) AND THEY SAID THEY DID NOT HAVE THE ABILITY TO DETERMINE IF ANYONE ELSE EVER HAD THE SAME PROBLEM.

Negative 2018 Toyota Prius prime car reviews

Kaleigh Rodriguez 2024-04-05

Hi there! I hope you're doing well. I wanted to share my experience with my 2018 Toyota Prius that I purchased in February 2019. I've driven about 6 thousand miles so far, but unfortunately, I had an accident 4 weeks ago due to unintended acceleration. It was a scary experience, but thankfully no one was hurt. Since then, I've been trying to get in touch with Toyota to investigate the case, but they have been quite slow in responding. I'm still waiting to hear from them. I understand that these types of complaints can take some time to resolve, but I was surprised by how bureaucratic Toyota has been in dealing with the case. As you may know, Toyota sells 3 million vehicles in North America every year, so I had high hopes for their customer service. I'll keep you posted on any developments every week. Thanks for listening!

I noticed that the front scoop bumper configuration may not be to everyone's liking as it may be prone to scratches and dings. The driver's seat has a lot of features and can be overwhelming at first, but I believe one would get used to it over time. Unfortunately, the rear visibility is not the best and could potentially be a safety issue. On a positive note, the car has great gas mileage, comfortable seats, and a spacious cargo/trunk. Overall, it seems like a great car with some minor drawbacks.

Updates 2/2024 - at 185,000 miles and still running strong! The only issues I've had were bad rear struts causing tire cupping, but it was doable to fix. I also had one rear wheel bearing go out. Overall, I consider this one of my most reliable vehicles to date. If you're looking for reliability, I highly recommend this Prius - it's my favorite generation so far! The seats are incredibly comfortable and it achieves great gas mileage. I do recommend a 240 V charger, which I was able to install myself for less than $300. It takes less than two hours to get a full charge of 22-25+ miles of electrical mode. While the lane departure assist could be stronger in putting the car back in the middle of the road, I do enjoy the adaptive cruise control. As someone who drives a lot (about 30,000 miles a year), I also love the heated steering wheel even more than the heated seats. The styling of the car is great and the headlights are amazing at lighting up the road, rain or shine. The menu can be a bit confusing at first, but you'll get the hang of it. It offers lots of options on how to customize your settings, which is a plus. One downside is that the Chi charger only works on Samsung phones, not iPhones. I used to own a 2010 Prius, but this car is far better looking. While the JBL stereo is nothing fancy, it does the job. I average 55 to 60 miles a gallon using hybrid mode and I get 22 to 25 miles on electrical after I plug it in. After 85,000 miles, it still runs reliably. The only thing I don't like are the tpms monitors, especially when I want to swap out and use winter tires that don't have tpms. The light stays on and can only be reset by a dealer or tire shop - you can't self-reset like you think you can.I'm so happy to hear that the 2020 models now have 5 seats! It's great to know that you've had a relatively trouble-free experience with your car, and that some things were even covered under warranty. It's also impressive that your brakes still look great, especially considering the amount of highway driving you do.
Carlos Wehner 2024-11-12

The continuous variable transmission is fantastic, especially when compared to the stuttering clutch issue my old Ford Focus had. I highly recommend this car to anyone looking to reduce their carbon footprint. And if you're really committed, you could even consider installing solar panels.
Merl Yost 2024-11-10

I had a good chuckle when I first read about the need to refresh the gas yearly. However, after owning my car for three months now, I still have over half a tank of gas left from the dealer. This is despite having driven 1,200 miles so far. I've come to realize that most of my daily travel involves trips of less than 30 miles, and the car claims a 25-mile range. Interestingly, the battery meter has at times registered capacity over 30 miles. What's more, I haven't noticed any significant change in my electric bill. I'm not sure how many miles I can travel before needing to refuel, but the car is so quiet when running on electric! UPDATE: During the year of Covid19, I only took short trips. I filled the tank in January 2020, and it's now June 2021, and the low gas light has just come on. The trip odometer says over 3,000 miles, and the gas mileage calculator says almost 350 MPG. I used mostly electric for over a year and a half at about $0.38 per 25-30 mile charge. Best regards, Roy Smith
Tony Moore 2024-11-01

I really love the Plug-In Hybrid design! It's so much better than Electric-only, which can require long recharging stops for trips farther than the battery-miles. The 2017 Prius Prime is perfect for my 15 mile drive to work, where I can also plug-in. I only use Gas when I drive the 20 miles to the City, don't plug-in and run out of Battery on the trip home. Then the efficiency of the Prius ICE allows it to get 55-60 mpg.
Percy Ritchie 2024-10-26

If you're looking to compare the Volt and the Prius Prime, there are some important factors to consider. The Prius Prime has a battery that is guaranteed for the life of the car, which is a game changer if you plan to keep the car for a long time. Additionally, the Prius Prime has better safety features than the Volt, especially the Advance model. The Prius is also more affordable than the Volt, and gets better gas mileage and driving distance. It's worth noting that Toyota dealerships are more numerous than Chevrolet dealerships, which could be a factor in routine maintenance or service. Overall, the Prius Prime seems like a better choice.
