Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“On the passenger side dashboard next to temperature control switch, dashboard vinyl is melting, it has bubble and one bubble was broken to make a hole. I noticed it on april 1, 2014. When I changed the cabin air filter on march,31 in glove compartment, I didn't see it. I brought my car to new country Lexus and described the issue hoping that their technician may see issue with temperature control resistance may causing wiring to heat that is causing vinyl to melt. …”

“I had a 2012 Lexus ES 350 and had problems with it. The first problem occurred when I was parking. I was angle parking and had my foot on the brake when the car jumped into a brick wall. Four air bags exploded in my face and rendered me unconscious. I was taken to the hospital in an ambulance. I could hardly walk and my legs were extremely swollen and I had many other bruises. The second incident was that the passenger seat of the car went on fire and burnt the seat. I feel I should not have to pay the final excess wear and tear bill of $829.50. …”

“The horn quit working. Found it works only when the steering wheel is turned close to end of clockwise and counterclockwise direction. Deemed safety hazard since no horn sound to alert pedestians, bicyclists and other drivers of danger. Wasn't covered under warranty and cost $690 to replace steering wheel clock spring.”

NHTSA complaint #11271116, filed 2019-10, 124,000 miles

“All 4 doors stopped locking by key fob, inside switches or exterior door handle switches or when putting the transmission in gear. No click is heard when trying to lock doors but clicking is heard when hitting the unlock switches. Doors will unlock electronically/ electrically when they are manually locked from inside the vehicle. A previous report indicated a similar problem that a dealer diagnosed as all of the door locks needed replaced, which makes no sense that the could all fail mechanically at the same time. …”

“Takata recall and electrical failures. Lexus recalled vehicle in jan 2017 warning that no one should sit in front seat for duration. No provision for a replacement vehicle was mentioned. It has been 10 months of not being able to use front seat. They say the parts will be available in december. Our vehicle is also getting my wife stranded. We have gone through 3 batteries in 3 years. Lexus refuses to fix it. Please reference attached recall letter. I was not able to attach the complete set of docs with detailed description due to file size.”
