Example complaints

Engine: “I'm extremely frustrated and disappointed in our check and balances with Audi and these safety recalls. I own a 2015 Audi A6, back in june I found that there are two safety recalls with the front airbags that have killed 20 and injured over 100 people. I've done a lot of research. The airbags are more likely to explode in hot states and I'm located in socal, particularly the valley, which is the hottest part of la, reaching 100 degrees + throughout the summer. …”

The vehicle was then taken to the independent mechanic where it was diagnosed that the coolant tank needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 79,000.”

NHTSA complaint #11620102, filed 2024-10, 79,000 miles

Electrical system: “Owner was notified of safety recall 19n4 - disconnect electric coolant pump and had the recall service performed on 29 dec 2018. Owner was informed that an additional safety recall (19o2) will replace the coolant pump with a new one. On 04 march 2019, we called Audi USA and were told that the replacement was not yet available. The coolant pump also aids in providing additional cabin heat which is important during the winter months for the comfort and safety of occupants in the vehicle. Due to the pump being disconnected, the cabin has been very slow to warn, including the window defrosters. …”
