2020 Had to replace transmission at 90,000 miles. In Sept. 2021 - Window seals are melting all over the windows. Will have to get them all replaced as a driving hazzard to even see out the windows. Now the tinting is coming off from the windows sticking.

This car is experiencing symptoms exactly as described in the inverter module recall, whereby after highway driving, the electric motor will fail randomly, tripping all dashboard failure lights, and putting the vehicle in "limp" mode, where it either slows significantly or stops, and then thus poses great safety risk with surrounding traffic.

3.5 L engine has problems with oil cooling pipe/hose. It leaks oil every 4 to 5 years. Danger is emptying the motor oil without notice. One can easily burn the engine if gone unnoticed. And get stranded anywhere without warning.

The contact owns a 2008 Lexus Rx400H. While driving 60 mph, the vehicle stalled and the ABS, brake system, and slip warning indicators illuminated. The vehicle was taken to carmax (3100 spur 482, irving, tx 75062, (972) 721-0500) where the contact was informed to ignore the failure and to bring the vehicle back in if the failure recurred. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 78,068.

RX400H

  • 136,000 miles
After my previous complaint of experiencing transmission shudders, the car became progressively worse. I had it taken to the local dealer, where they informed me that the transmission had failed. This car has only 136,000 miles, which is not many for the quality usually associated with the Lexus brand. They claim to have no reason for the failure, but are charging me almost $5,700 to replace it. I asked Lexus corporate to assist me with this repair, due to the known transmission issues on many Rx models, but they declined. The vehicle almost died on me in the middle of the highway on several occasions while experiencing these transmission shudders, which could have led to a bad accident. I think this is ridiculous and shows poor quality in their manufacturing.
