Example complaints

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

“I was driving on the parkway with my family and I was traveling at approx 60 MPH. Out of no where a tcs and ABS light came on the I decreased to 5 MPH without warning and couldn't go faster. I had my foot all the way down to the pedal and vehicle wouldn't drive. This appears to be a camshaft sensor issue from what I see. There was a recall on this issue but I'm being told my vehicle was not an affected car. Others have all had the same happen with this same vehicle and I find it strange that because our VIN numbers weren't recalled that we are out of luck. …”
