Example complaints

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

“I have had an ongoing issue with my '04 Lexus rx330. I am concerned because the engine needle goes into the red zone almost immediately upon driving the car. I have had to fill up the coolant tank every 3 months. The problem was just diagnosed as a crack in the radiator. I found a TSB for this issue but am the 2nd owner and was never notified. It appears that I am out of the coverage period. Is there cause for concern that this issue could lead to further damage to the car or a sudden driving impairment? Does a TSB = a recall? Lexus has told me that there is nothing they can do for me.”

NHTSA complaint #10558341, filed 2014-01, 115,000 miles
