Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I had my car diagnosed and the machine said my air flow sensor was bad but in all actuality it was a vacuum pump. My dad took the pump off and there was so much grit in it my motor wasn't getting the proper air. The problem is in all my years of owning vehicles I've never changed a vacuum pump. Then the cylinder inside the pump was in about six pieces and broke.”

NHTSA complaint #11013657, filed 2017-08, 59,000 miles“The object sensor modules that control safety features like blind spot alerts and gap alerts have failed creating more problems for my vehicle. This is a major safety concern and should be recalled by chevy. My dealership said that my extended warranty will not cover this issue even though it is ultimately an electrical problem and nothing I did created this major issue. This issue occurred while I was driving and immediately had an effect on my driving condition.”
