Example complaints

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

“My steering started getting stiff and making a grinding sound without warning. It would then disappear after driving for about 5 minutes. I noticed this seems to be a common problem with the vehicle at the 90,000 mark. I bought a Lexus because I thought the vehicle would be solid but it seems like everything is starting to go. I had to replace the sunroof, air conditioning pump, radiator and transmission after hitting 80,000. I don't want to put any more $$$ into the car at this point because it doesn't seem worth. One problem after the next.”

“I bought my Lexus in 2007. It is a 2004 rx Lexus 330 it had 31,000 miles when bought. Since I had the car my radiator was broken and the Lexus dealership repaired it under warranty. Before this I remember stopping to the dealership because felt the car was stalling and was told that nothing wrong its just I have to be consistent the way I drive with speed. Now in 2010 I'm experiencing the same problem with the car stalling or lagging with the RPM and a little noise coming from the transmission. …”

“2004 Lexus rx 330: I was a victim of sudden unattended acceleration. This occurred on drive pavement on a street with an uphill grade. I was about to park my vehicle behind a parked car. As I was coasting to stop, my foot was barely touching the gas pedal - I was within a few feet of the parked vehicle. Suddenly I heard a clicking sound and immediately I felt the pedal leave my foot. The car engine revved to the highest RPM. The Lexus slammed into the parked car. I tried braking and there was no response. …”

“Dear sir/madam: I am writing you because I am being ignored by a large product manufacturer. Lexus/toyota is refusing to hear my claim or even consider my situation on the car. I have not had my claim denied by Lexus because they simply will not even consider my issue. I am the owner of a 2004 Lexus rx 330 that has a failed engine due to oil sludge. I have always had my vehicle maintained at a Lexus dealership and I get the oil changed in a timely manner. My car has 110,000 miles on it and last sunday the engine failed in the middle of an intersection. …”
