Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
0
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

That does not guarantee a specific vehicle is unaffected — recalls are issued against VINs, and new campaigns are announced regularly. Check a VIN on NHTSA.gov.

At approximately 43,044 miles, my 2021 Audi A7 55 TFSI e quattro (PHEV) was diagnosed with a failed N632 coolant changeover valve — a component of the PHEV thermal management heating circuit. The vehicle has a complete, documented service history with no maintenance gaps. The N632 is an electronically controlled valve that routes coolant between the combustion and hybrid/electric circuits and is essential for cabin heating in EV mode, battery pre-conditioning, and engine warm-up. Failure of this valve can result in loss of cabin heat, coolant leaks into the engine bay, and potential cascade of electrical faults if coolant migrates into the wiring harness. The repair estimate is $1,700. The factory warranty, Audi Care plan, and third-party extended service contract (United Car Care Protection Plus) have all denied coverage. This failure on a low-mileage PHEV with full service history suggests a premature component defect in Audi's PHEV thermal management system. I am requesting NHTSA investigate whether this constitutes a pattern of failure across 2021 Audi PHEV vehicles.

The warning ‘drive system failure’ appears while driving and tells you to stop the car immediately. This happens randomly while driving on a highway. The engine now makes a higher pitched noise and then the transmission will no go into drive it immediately goes into neutral, the car slows down and you must pull over as you have no control over the car. The gas doesn’t work. There are so many alerts that pop up with a malfunction- parking brake, transmission, distance warning, audi presense warning, tire pressure malfunction, transmission malfunction. BEFORE this- There was an issue found when a check engine light appeared after the car failed emmissions testing. Control Pilot Circuit High and AC refrigerant pressor sensor B circuit failures listed. The car went to Audi and they said it was an air conditioning issue and other faults. The cleared the faults and signed off on the emmissions paperwork. I told Audi of the issue when getting it serviced- they could not replicate the random drive system failure alert. Again the same issue- bring it to audi- they had it for a week or so- still cannot replicate the issue. A few weeks later while driving on I91, the driver system alert comes on and there was a high pitched sound car goes into neutral- I have no control over the vehicle and coast down 2 roads and into a driveway of a volkswagen dealership in an unsafe area of Hartford. I then started the care up and took it to Audi of East Hartford. The replicated the issue they said and replaced the entire EOC unit for almost $7000. They had the car for a month. Then after having it back a couple of weeks it randomly does it again and restarting the car would reseg it only once and then another alert and the car dies on the highway and I again lose control and pull over to the shoulder. VERY VERY unsafe. The car just dies randomly on a highway. It happened in May of 2025, June and July. July 15 was the most recent immediately after being ‘repaired’.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
