Example complaints

“Car dies after driving for a bit. We've spent over $3k fixing fuel pump, batteries, and others. From what I'm reading it sounds like my car should be on the inverter recall list, but it's not.”
NHTSA complaint #11374985, filed 2020-11, 130,000 miles“From what I have been reading on that year and model, there seems to be major issues with the invertors. Like many I was driving on the highway and the vehicle just quits. This put me and many others in a very dangerous situation and I could have been hit at high rates of speed. If as many people are having these issues, then Lexus needs to step up and recall this part before someone gets killed”
NHTSA complaint #11648884, filed 2025-03“My car exploded- huge fire. I was not driving- it had been parked. The fire marshal indicated that it was an electrical problem located near the battery. There we no indicators of any issues. I only had liability on the car- so i am out of luck. but the NYFD inspected. It happened on Wednesday 9/29/21. Was inspected on 9/30.”
NHTSA complaint #11435153, filed 2021-10“The power steering and hybrid system failed and vehicle completely stopped in middle of busy freeway with no prior warnings or issues before. The safety of my son and I, and others around me during the abrupt stop of the engine. I could not move out of way. The vehicle has been serviced for this exact issue during a recall campaign lasting from 2011 to 2014. Ten years later and it is still happening! There were NO warning lamps or messages or symptoms prior to this failure. It just passed vehicle inspections for the year”
NHTSA complaint #11631799, filed 2024-12“Dear manager: I have this 2006 LEXUS RX400H which has CHECK VSC SYSTEM and CHECK HYBRID SYSTEM problems. When I was driving on the highway, the cruise control button is unable to turn on, when at speed of 65 MPH it will suddenly stall in the middle of the road and the READY light will be off and the vehicle has to be stopped by the emergency lane which is REALLY DANGEROUS. I have searched online and found out there were many complains about this issue and LEXUS issued a recall for this type of car and the dealer can change the inverter and ICM free of charge. …”
