2007 Lexus Rx400h problems
The Lexus RX (Japanese: レクサス・RX, Hepburn: Rekusasu RX) is a luxury crossover SUV sold since 1998 by Lexus, a luxury division of Toyota. Originally released in its home market of Japan in late 1997 as the Toyota Harrier, export sales began in March 1998 as the Lexus RX.
Considered as the first luxury crossover SUV, five generations of the RX have been produced to date, the first being compact in size, and the latter classified as mid-size. Both front- and four-wheel drive configurations have been used on the RX series, and several gasoline powertrain options, including V6 engines and hybrid systems, have been offered. In the Lexus model lineup, the RX sits below the larger Lexus LX (marketed as the Toyota Land Cruiser body-on-frame SUVs outside North America, respectively), and above the shorter and less wider, but taller GX SUV. The name "RX" stands for "Radiant Crossover". It has also been labelled as "Recreational Cross Country" in some markets. The RX's current Toyota counterpart is the Highlander/Kluger; past counterparts included the Harrier and Venza.
The first-generation RX 300, fitted with a 3.0-liter V6 engine, began sales in 1998. The Japanese market Harrier released in 1997 also offered a 2.2-liter inline-four, later uprated to 2.4 liters. The second-generation RX 300 (3.0-liter V6) and RX 330 (3.3-liter V6) models went on sale in 2003, with both variants supplanted by the more powerful RX 350 (3.5-liter V6) in 2006. Like the previous series, a 2.4-liter inline-four engine was sold alongside the 3.0-liter V6 in the Japanese market Harrier. In 2005, a hybridized gasoline-electric version of the 3.3-liter second-generation model was made available as the RX 400h in export markets and as the Harrier Hybrid in Japan. For the third generation released in 2009, both RX 350 (3.5-liter V6) and RX 450h (3.5-liter V6 hybrid) models were initially offered, with an entry-level RX 270 (2.7-liter inline-four) offered by Lexus in some Asian markets, including in Japan, since 2010. Since the release of the third generation, Japanese sales have occurred under the RX name as opposed to Harrier as had been the case previously. In the fourth generation, a turbocharged (2.0-liter inline-four) RX 200t/300 model was introduced to replace the previous 2.7-liter unit.
The RX has been assembled at Toyota Motor Kyushu since launch. The RX and RX Hybrid were the first Lexus models to be built outside Japan, with North American market versions produced at the Toyota Motor Manufacturing Canada plant in Cambridge, Ontario beginning 2003 (RX) and expanded in 2014 (RX Hybrid). Hybrid transaxles are built at the Kokura plant in Kitakyushu, Fukuoka since 2009.

Common 2007 Lexus Rx400h problems
Based on complaints from owners of the 2007 Lexus RX400h, several common problems have been identified:
- Hybrid Battery Pack: The hybrid battery pack has been reported to fail before 100,000 miles in some vehicles, which can be a costly component to replace.
- Braking System: Some owners have experienced braking problems with the regenerative braking system, requiring extra pressure on the brake pedal or issues with the braking system not working properly. A software upgrade or dealer intervention may be necessary to address these issues.
- Rattling Noise from Rear Seats: Owners have noticed a rattling noise coming from the rear seats, especially when driving over speed bumps or poorly surfaced roads. This issue is caused by poor fitments of the rear seats, allowing for some play in the seat mechanism. Adjusting and tightening the rear seats can resolve this problem.
- Inverter Leaks: There have been reports of the inverter leaking coolant, which can be identified by lower liquid levels in the inverter coolant reservoir or a crusty pink substance around the inverter. Replacing the inverter can be expensive, but if the vehicle is under warranty, Lexus may cover the cost of repair.
- Climate System Issues: Problems with the climate system, including the AC compressor, blower motor, condenser, evaporator, and heater system, have been reported. Issues such as engine stalling when the compressor kicks on, electrical failures, refrigerant leakage, and costly repairs have been highlighted by some owners.
These common problems with the 2007 Lexus RX400h should be carefully considered by potential buyers or current owners to ensure proper maintenance and address any issues promptly.
How long does a Lexus RX 400h hybrid battery last?
But generally, a Lexus hybrid battery can be expected to last between 100,000 and 200,000 miles. The good news is, the typical Lexus hybrid comes accompanied by a hybrid battery warranty that is good for 10 years or 150,000 miles.
Is the Lexus RX 400h reliable?
Absolutely reliable and a great car to own/drive
Now in 2023 it has 174,000 miles. It still runs like new, handles well, and is very comfortable. I have done maintenance and just did the Timing belt, spark plugs, and CVT fluid change. Toyota replaced the inverter under a recall so no issues there.

FUEL/PROPULSION SYSTEM PROBLEM
- Date Of Incident: 2023-10-01
- VIN: JTJHK31U472
- Components: FUEL/PROPULSION SYSTEM
- Summary: Oil Cooling line failed when driving. I was not aware that it was having an issue; the oil completely cleared the engine, and this could have seized the engine while I was driving. The only way I figured it out, I stopped the car at some point and saw a pool of oil under the car. I called AAA and they came to tow the car, and checked the engine, and told me that there was no oil in the engine.

STEERING,ELECTRICAL SYSTEM,SERVICE BRAKES PROBLEM
- Date Of Incident: 2022-08-06
- VIN: 2t2hk31u37c
- Components: STEERING,ELECTRICAL SYSTEM,SERVICE BRAKES
- Summary: Electrical system malfunction began (to my best calculation & recollection) in summer 2021 with the first of four battery malfunctions in one year. Each time, AAA discovered low battery response and recommended battery replacement. This time around, battery was replaced about two weeks prior, due to battery failure/AAA reporting would not accept charge. THE NEW BATTERY FAILED (8/3) and the starter broke while attempting to charge. Mechanic repaired starter and battery accepted the charge. No problem, right? Wrong. This driver drove about 30 miles and while driving, the electrical system shut down altogether. With I believe ALL WARNING LIGHTS LIGHTING UP, extremely dangerous situation. NO BREAKING, NO STEERING, NO WARNING. Fortunately, it occurred in a suburban residential area as opposed to the highway. SECOND tow to my mechanic and now, after a full week, no diagnosis, though the car has been running in the shop. This is an intermittent problem. I suspect the alternator.

STEERING,SUSPENSION,FUEL/PROPULSION SYSTEM PROBLEM
- Date Of Incident: 2021-11-19
- VIN: 2T2HK31U17C
- Components: STEERING,SUSPENSION,FUEL/PROPULSION SYSTEM
- Summary: On November 19, 2021, I purchased a vehicle from cars Lane on Hanover Road in Annapolis Maryland. Upon driving back to my residence in Gaithersburg I noticed that there was significant shaking when the vehicle was driven over 60 miles an hour. I notified the dealership and seemed helpful at first. I took the car to a good year facility and pay to have an alignment. That seem to fix one of the issues however there were several more and many more I was later to find out. As well, the vehicle was also hard to steer when it came to trying to back up and turn the steering wheel. It also made a loud whining noise. I contacted the dealership again and told them of this problem. I have been out to the dealership several times upon realizing they do not have a mechanic on duty and whoever passed inspection on this car should be investigated. There is no way that this car should've passed inspection. The last time I went to the dealership upon talking with the owner I was told to bring the car in and they would take a look at it. Looking at it was all they did. I noticed that [XXX] was on the phone with the warranty people trying to determine if the items that I complained about were covered under the warranty. The woman on the phone informed him that they only covered a certain point of the cost. Now I have come to find out that this car has over $17,000 worth of work to be done. I would like to make a formal complaint about this dealership, its representative [XXX] and the mechanic that allegedly passed this vehicle for inspection. I welcome the opportunity to speak with you and supply you with all the necessary documentation concerning this matter. I have included a copy of the estimate from the Lexus dealership in Rockville, Maryland. It is my honest opinion that this car should've never been sold and have lied to me in the process and to throw the paperwork at me and tell me to take care of myself is unacceptable. They should be held accountable, fined, or shut down. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

SERVICE BRAKES PROBLEM
- Date Of Incident: 2021-09-01
- VIN: JTJHW31U572
- Components: SERVICE BRAKES
- Summary: Toyota and Lexus are aware of the fact that what is called break actuator assembly, part number 44050-48191 (for Toyota Highlander Hybrid 2006-2007, and new part number for Lexus RX400h 2006-2007) and 44510-48060 (old/original part number for RX400h 2006-2007) are faulty resulting in the break system failing creating an extremely dangerous situation. Toyota extended the warranty for the part, but this extended warranty does not cover all vehicles, as it is not a recall. (The extended warranty has a maximum 150K miles or 10years clause but this is beyond the point regardless.) The part and repair costs more then $3000 at a Toyota/Lexus dealer. Toyota/Lexus is not offering a recall to avoid paying for the large number of cars out there with this well known issue which essentially renders the cars not drivable, unless the owner pays out of pocket what is close to half the current value of the car, for a defective item that is failing consistently in all these cars. Toyota/Lexus should recall the part, rather than just offering an extended warranty. This is a very well known problem, for which people have complained (including in NHTSA) for years, which forced Toyota/Lexus extend the warranty, but this is not enough as it does not cover all vehicles that it should cover.

SERVICE BRAKES PROBLEM
- Date Of Incident: 2021-02-20
- VIN: JTJGW31U172
- Components: SERVICE BRAKES
- Summary: CAR HAS BEEN MAKING A CLICKING NOISE DURING STOPS FOR A YEAR. I CHALKED IT UP TO SOMETHING UNIMPORTANT. ON 2/20/21, THE 'CHECK AVS,' 'CHECK ABS,' AND 'CHECK BRAKE SYSTEM' LIGHTS ALL CAME ON, AND CAR LURCHED WHILE BACKING OUT OF MY DRIVEWAY. I WAS DRIVING MY WIFE AND DAUGHTER AT THE TIME. BROUGHT LEXUS TO MY LOCAL MECHANIC ON 2/22/21. AFTER SEVERAL DAYS, MECHANIC RETURNED THE CAR TO ME, SAYING HE COULD HEAR THE CLICKING AND, ACCORDING TO HIS RESEARCH, IT COULD BE THE BRAKE ACTUATOR GIVEN LEXUS HAD DONE A WARRANTY EXTENSION ON THIS PART IN 2016. HE TOLD ME THIS REPAIR WOULD COST IN THE THOUSANDS OF DOLLARS, AND ADVISED ME TO CONTACT LEXUS. SPOKE WITH LEXUS BRAND MANAGER ON 2/25 WHO TOLD ME ABOUT WARRANTY EXTENSION ZLG FOR ACTUATORS IN 2016, AND TOLD ME THAT IN ORDER FOR LEXUS TO ASCERTAIN WHETHER OR NOT THE CAR WAS EXPERIENCING AN ACTUATOR FAILURE, IT MUST BE INSPECTED BY A LEXUS SERVICE CENTER. BECAUSE I WAS TOLD ABOUT THE SPECIFIC EXTENSION AND ASKED TO TAKE IT TO LEXUS TO DIAGNOSE THE ISSUE, I ASSUMED LEXUS WOULD COVER THE REPAIR COST. I TOOK THE CAR TO LEXUS SANTA MONICA ON 3/2/21 AND WAS NOTIFIED THAT THE PROBLEM WAS RELATED TO THE BRAKE ACTUATOR, AND THAT THE COST TO REPAIR WOULD BE $3000 PLUS TAX. I RELAYED TO LEXUS SM WHAT I WAS TOLD BY LEXUS CORPORATE, AND LEXUS SM TOLD ME THEY WOULD CALL LEXUS CORPORATE AND SEE WHAT THEY HAD TO SAY ABOUT WARRANTY EXTENSION 'ZLG.' ULTIMATELY, LEXUS WOULD NOT COVER COST BECAUSE THE PART WAS OUTSIDE THE EXTENDED WARRANTY. I SPOKE WITH ANOTHER LEXUS CASE MANAGER ABOUT WHY A WARRANTY EXTENSION WAS OFFERED AS OPPOSED TO A RECALL, AND HE SAID I SHOULD LODGE A COMPLAINT WITH NHTSA. I ALSO SPOKE WITH HIS SUPERVISOR, WHO SAID LEXUS WOULD NEVER PAY FOR A PART OUTSIDE A WARRANTY, EVEN A FAULTY PART GIVEN AN EXTENDED WARRANTY. NOBODY IN THE LEXUS CHAIN OF COMMAND CAN TELL ME IF THE CAR IS SAFE TO DRIVE. I WILL SUPPORT CLASS ACTION SUIT.

ELECTRICAL SYSTEM,UNKNOWN OR OTHER,SERVICE BRAKES PROBLEM
- Date Of Incident: 2020-10-02
- VIN: JTJGW31U572
- Components: ELECTRICAL SYSTEM,UNKNOWN OR OTHER,SERVICE BRAKES
- Summary: "CHECK VSC" SYSTEM WITH ACCOMPANYING CONTINUOUS BEEP NOISE, BRAKES BECOME HARD TO PUSH/ACTIVATE. THIS STARTED A FEW WEEKS AGO, AND WOULD HAPPEN INTERMITTENTLY, AND PROGRESSIVELY LONGER IN THE DYSFUNCTIONAL BRAKES PHASE. I HAD AN EMPLOYEE AT AUTO ZONE CLEAR THE CODE 2 DAYS AGO, BUT THE PROBLEM STARTED AGAIN, INTERMITTENTLY UPON VEHICLE START, BUT WOULD GO AWAY SHORTLY, WITH NORMALLY RESPONSIVE BRAKES. THIS INTERMITTENT ISSUE OCCURS WHEN I AM DRIVING, THEREFORE THIS IS A SERIOUS ROAD HAZARD AS MY BRAKES BECOME SIGNIFICANTLY LESS RESPONSIVE WHEN THE PROBLEM OCCURS. IN OTHER WORDS, THIS OCCURS WHEN STATIONARY AND WHEN DRIVING, INTERMITTENTLY.

ENGINE PROBLEM
- Date Of Incident: 2020-09-22
- VIN: 2T2HK31UX7C
- Components: ENGINE
- Summary: I PURCHASED A USED 2007 LEXUS RX350 FOR MY 16 YEAR OLD DAUGHTER. IT HAD A LITTLE OVER 100K MILES. EVERYTHING WORKED PERFECTLY, NO COMPLAINTS WHATSOEVER. UNTIL, MY SON BORROWED IT, AND WHILE HE WAS DRIVING IT, HE SAID IT QUIT. HE LOST ALL POWER STEERING, SO HE PULLED OVER. WE CALLED A TOW TRUCK TO TOW IT TO A MECHANIC. WHEN THE MECHANIC CALLED ME, HE SAID THE OIL COOLING LINE BUSTED, WHICH MADE THE OIL PUMP EMPTY THE ENGINE'S OIL. HE SAID IT WOULD NEED A WHOLE NEW ENGINE. HE SAID THE CAR IS WORTH NOTHING. I PAID $9K FOR THIS CAR A YEAR AGO, AND NOW IT IS NOT WORTH $100. THE MECHANIC SAID THIS IS A KNOWN PROBLEM FOR TOYOTA/LEXUS, BUT THERE WAS NO RECALL. TO ME - THIS IS UNACCEPTABLE. IN MY OPINION, SINCE TOYOTA KNEW OF THIS PROBLEM, BUT DIDN'T RECALL IT, THEY EITHER NEED TO COVER THE COST OF A NEW ENGINE, OR BUY THE CAR BACK FROM ME. I AM VERY UPSET OVER THIS.

2007 Lexus Rx400h recalls
The National Highway Traffic Safety Administration (NHTSA) has issued 3 recalls for different components of the 2007 Lexus Rx400h.
2013-09-04
- Manufacturer: Toyota Motor Engineering & Manufacturing
- Components: HYBRID PROPULSION SYSTEM: INVERTER
- Summary: Toyota is recalling certain model year 2006-2010 Highlander hybrid vehicles manufactured February 16, 2005, through July 29, 2010; and model year 2006-2008 Lexus RX400h vehicles manufactured February 23, 2005, through December 2, 2008. The Intelligent Power Module (IPM) inside the inverter module may contain transistors that have higher operating temperatures than the solder can support and the transistors may be heat damaged by the solder. If this occurs, various warning lamps, including the malfunction indicator lamp, slip indicator light, brake system warning light, and master warning light, will be illuminated on the instrument panel.
- Consequence: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. It is possible that the hybrid system will shut down while the vehicle is being driven, causing the vehicle to stall unexpectedly, increasing the risk of a crash.
- Remedy: Toyota will notify owners, and dealers will replace the IPM free of charge. Owners may contact Toyota at 1-800-331-4331. Vehicles that had their IPM replaced under recall 11V-342 are not affected by this campaign.

Negative 2007 Lexus Rx400h car reviews
Positive 2007 Lexus Rx400h car reviews
-
The 400h has great acceleration and is a well-built, comfortable car. Its average gas mileage of 28 MPG is consistent with other reviews. However, the navigation system is the worst part of the package. On the other hand, Acura has an excellent navigation system.
-
This car is especially high-performing for mountain driving. I appreciate the low emissions, which not only help the environment but also enhance the pleasure of driving this car.
-
I have 170k on my 400h. I've put around 100k miles on it since I've owned it. It's been the best vehicle I've owned by far! It's been so reliable and smooth. Simply the best!
-
This has been an exceptional vehicle in all respects! The local dealership has been excellent since purchase. All service has been completed in a timely fashion and with great care for our time and convenience.

The navigation system can be quite complicated, even for someone with a PhD in Engineering like myself. Additionally, the cargo space may be a bit shallow and the screen can be difficult to read in bright daylight. However, the car's performance is quite good and it has proven to be very reliable. While I personally prefer the Mercedes S-Class, the Lexus is still a great option.

Before purchasing this vehicle, you may want to consider a few things. I am 5'6
Alejandrin Lang 2024-03-12
I hope this message finds you well. I wanted to share my experience with the Lexus vehicles I have owned. I am a proud owner of an LS 430, which I believe is the best vehicle I have ever owned. However, I have been a bit disappointed with my RX400h. The fuel economy has been below my expectations, averaging 19-20 mpg in normal driving, which is mostly in town, and 22-23 mpg on a trip. I have reached out to the dealership about this, but unfortunately, they have not been able to provide a satisfactory solution. I have noticed that the gas engine cuts in at too low a speed, which may be contributing to the issue. Additionally, as someone who is 6'2
