Example complaints

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

“I brought my car in for service on 9/10 and had my brake booster and water pump replaced. I was out of town following that and did not drive my car much. On 9/21, I got into my car and the navigation screen was not working. It displays correctly and the backup camera works but it is unresponsive to my touch. I cannot adjust the air, radio, or navigation. I read many, many forums online of people having the same issue as me.”

NHTSA complaint #10544954, filed 2013-09, 93,400 miles

“My car is a 2008 with only 61k miles on it. The airbag light came on and I took it into the dealer. They said there was an issue with a wiring squib and my entire airbag system was shut down. If I had gotten into an accident, not one airbag would have deployed. The dealer said to fix it will mean replacing the entire wiring harness at a cost of $2500. Per the dealer, this is nothing that happened over time or through wear and tear. Also, the dealer said by replacing the entire wiring harness, I was replacing items that were not malfunctioning as this was the direction per Lexus. …”
