Example complaints

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

“Vehicle was garaged and functioning under normal conditions. Appx. 64000 miles. When the car was turned on and put in reverse, the rearview camera's view was moderately visible, but garbled past any useful view. This did appear to happen after the trunk was simply opened and shut before getting in the car, although that should hardly affect the ability for the camera to work or not. The next time I started the car, I did not open the trunk, and the problem persisted. The time after that, I opened the trunk and shut it and it went away. Then it came back. …”

“Check engine light cuts on with overheating and eps error when starting car sometimes. When you shut off car it cuts off and returns to normal. It started last year and has continued, I was told it may be a sensor shortage.”

“Audi baton rouge informed me there is a problem with coolant migration at coolant tank connector (coolant could leak into wire harness) and cause severe damage to electrical system want $300 +_ to repair. Since this is not something caused under normal conditions or negligence on my part I do not feel I should be responsible for cost of repair, should be a recall on Audi”

“I purchased my 2016 Audi A3 in April of 2020 from Audi San Diego. Less than a year later, I was getting airbag warning lights on my dash, as well as constant warning sounds when driving. I brought my vehicle into Audi San Diego, and they fixed the issue free of charge. A few months later, I started getting the same warning lights/sounds - this time, the passenger airbag was turning on and off even while somebody was sitting in the passenger seat. I received a recall letter in the mail shortly thereafter. …”
