2020 Audi Q7 owner complaints

Emergency battery light came on with a description of power malfunction. The light went from yellow to red then shortly stopped in the road while driving with complete power outage.

Two issues: the small portable air pump that came with the car would blow the fuse to the 12v cigarette lighter. After a new fuse is put in, this would happen on about every third or fourth time of using of the pump. I have replaced about 5 fuses already. The second issue is the squeaking of the rear brakes when backing up during cold or hot. However, it does happen more when cold/in the morning. A factory dealership had look at the issue but found nothing.

While driving, Forward Collision Warning appears without any reason. My understanding is that the car will brake itself if it senses frontal collosion and I am concerned that it might brake suddenly without my knowledge and cause an accident.

While driving at high speeds on the Freeway with my wife and 2 children (ages 4 & 5), an alert on the dashboard said - Electric System Malfunction. Drove straight to the near by dealership and was told not to turn off the vehicle as it might not start. Service Advisor said we were lucky it didn't stop on the freeway as it has for others. He asked us to collect our belongings as the car was not drivable due to a known electrical system malfunction. He said this was a known issue as there were many others impacted with this same issue and have been waiting months for the parts. He also said Audi of America is well aware of the issue but don't want to publicize it as they don't have the parts available to repair all the impacted vehicles. He provided me with the Audi TSB 27 22 41 showing th

I am filing a complaint concerning serious safety risks associated with my 2020 Audi Q7 (VIN: [XXX] ) purchased as a Certified Pre-Owned vehicle from Audi Dominion San Antonio. It is currently under service at Audi Central Houston, where multiple concerning events occurred. Timeline and Issues: - Initial diagnosis identified a fire-damaged electrical harness, estimated at $1,400 for replacement. - After repair attempts, the vehicle began smoking, and the diagnosis expanded to include additional compromised electrical lines. The revised quote skyrocketed to $4,700 (later reduced to $3,100). - After nearly two months in service, I was informed that the AC compressor is now deemed "bad" due to debris from the harness, an issue not mentioned in previous inspections. Safety Concerns: 1. Incons

while driving the vehicle, I received a warning that there was an electrical system failure. Then the entire care shut off in the middle of the highway. There was no way to get the vehicle into neutral to push it to a safer location out of traffic. I was in the vehicle with my two children. This left us stranded in the middle of the highway with a significant amount of traffic. There was no way to get the vehicle back on. This seems to be a known issue with Audi and they have notified the dealerships about it but have not issued a recall. Please expedite this as a recall. There could not have been a more dangerous situation for me and my children.

The contact owns a 2020 Audi Q7. The contact stated that while driving approximately 55 MPH, the messages "Electrical Malfunction" and "Stop Vehicle" were displayed. The contact stated that moments later the vehicle shut off and failed to restart. The vehicle was towed to the residence and later examined by an independent mechanic who diagnosed that the alternator was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were contacted regarding the failure, but no assistance was provided. The failure mileage was 70,000.

Turbo charger failure at approximately 30,000 miles

I’m having to replace my REPLACE WATER PUMP AND VACUUM LINES WITH RESERVOIR at 41k miles or it risk overheating the engine. It is a significant repair at a premature time. After researching, it has been reported there are historical issues with this and faulty parts.

I urgently request a NHTSA investigation into systemic coolant leaks, a dangerous safety defect in Audi vehicles with the 3.0L turbocharged V6 (EA839) engine. Affected models include the Q7 (my 2020 Q7 55 TFSI, VIN: [XXX] ), S4, S5, SQ5, A6/A7, Q8. These defects risk engine damage, sudden power loss, and catastrophic engine failure, endangering all road users. Many owners report premature failures of cooling components (water pump, thermostat, PCV system). Failures often occur post-warranty, costing owners over $3,000 for repairs. Online forums (AudiWorld, Audizine, Reddit) document these widespread defects. The class action [XXX] et al. v. Volkswagen Group of America, Inc. alleges water pump defects in EA839-equipped Audis (incl. Q7 up to 2022). Critical Safety Concerns: The primary sa

the first indication of an issue was oil consumption. It was using more oil than usual around the 70K mile mark. Then it started misfiring, and soon after a knocking noise coming from the engine. There are no check engine light on, after bringing it in for diagnostics, it read that it was a spark plug, once they got into the engine they discovered the cylinder had been stripped from the piston. Yes the diagnostics came from our foreign car mechanic. no, it has not been inspected by the manufacturer or police. Just the symptoms. sometimes the light would come on, and then it would go off. At this point it is off. All of this started in the fall of 2025.

While my vehicle was in for the Audi piston issue, they stated my water pump needed to be replaced and isn’t covered by a recall (yet). My vehicle had less than 42,000 mile on it. I was lead to believe that this problem is coming up more often and they believe a class action lawsuit will come about. I needed to pay over $1,700 out of pocket and was told I was saving so much money because they already had the engine apart because of the piston recall. This is unacceptable.

The contact owns a 2020 Audi Q7. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly downshifted while the accelerator pedal was depressed. The check engine warning light was illuminated. The vehicle was taken to a local dealer, where the water pump, coolant pump, vacuum line, and vacuum reservoir were replaced. The manufacturer was made aware of the failure. The failure mileage was approximately 70,000.

Panoramic sunroof imploded while traveling at freeway speeds (70mph) during normal conditions (no rain, hail, snow, etc. and 60* temp) causing a large amount of glass to be blown into the cab of vehicle, striking the driver and passenger. With this loud implosion and visibility obstructed by flying glass debris it put the driver in a unsafe environment. This also put the passenger and other drivers on the road at a huge risk of an accident. Throughout the automotive industry, this has been a known issue over the past several years and even at the local Audi dealership in Bellingham, WA. After conversation with dealership there was no known contributing factors to the implosion and was suspected to be a manufacturing defect.

The Audi 2020 q7 experiences an SOS Emergency contact communication failure when it goes of cell service range and in certain circumstances, it does not reset itself Or allow reconnection to the communication module after it goes back in range within cell service. This is a know issue, similar to Audi service Bulletin 90T2 in which the NHTSA issued a recall (The Q7 model is not covered under That recall, but several other models within the same year are covered). As a result of this software bug, in certain circumstances, it the communication module may not be able to contact emergency services. Audi America dealerships require payment and charge consumers $276 for drivers to update the MMI system To correct the software “bug.” Due to the fact that it is a Software issue, which requires up

When driving with the cruise control on, the vehicle automatically adjusts the speed to the speed limit. On occasion, when driving at freeway speeds, it will pick up the speed limit from a cross street (over or under pass). This happened on a recent trip with the vehicle set at the speed limit of 75, then suddenly and automatically braking because it detected a 45 MPH cross street. With most traffic moving at 75 MPH, this was extremely dangerous to suddenly brake for no apparent reason with people right behind us. We can no longer us our cruise control because of this. The Audi dealership could not replicate this issue. It only happened to us in a small number of circumstances, but was dangerous and frightening when it did. The automatic speed adjust also apparently cannot be turned

Central control module failure. Item is under recall for various Q5 models. Q7 is essentially the same car with same water intrusion problem. Why isn’t it included in recall. Very dangerous stall.

In July 2023, my 2020 Audi Q7 experienced a complete electrical failure at highway speeds due to a Belt Starter Generator (BSG) malfunction. Audi replaced the BSG with the same faulty part. Months later, I noticed increased oil consumption and loud engine noise. Despite multiple service visits and reporting these issues, Audi failed to properly diagnose the problem. In January 2025, despite a clear check engine light indicating a problem, Audi dismissed my concerns. Just weeks later, in February 2025, the engine catastrophically failed due to undiagnosed internal damage. Audi repeatedly ignored diagnostic warnings and failed to address my complaints, putting my safety at risk. Audi consistently dismissed my concerns, attributing engine noise and oil consumption to normal wear. The failure

Often gets warning about Parking Brake malfunction. Dealership already checked once and could not find the problem. Warning comes on speedometer as follows: "Parking brake: malfunction! Please contact Service."
