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 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.

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.

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 they knew about it since at least March 2021 (Attached).

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 updating by the dealership, Extended warranties do not cover fees associated.

FORWARD COLLISION AVOIDANCE

Government / agencyIndexed Oct 9, 2026Source-linkedVerify source — NHTSA complaint #11400113

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 off. The dealership did mentioned they were aware of another Audi vehicle they had seen with the same issue.

Received a yellow "electrical failure" warning while driving, instructing me to call Audi for service. Audi indicated that the car remained safe to drive, and offered a service appointment greater than one month later. Driving the car the next day, the electrical failure icon converted to red and a message said to pull over immediately. The car was able to make it to a local repair shop, with electrical systems failing one-by-one (starting with heating and progressing from there). On reaching the shop, the car was no longer driveable and had to be pushed into the garage to be assessed. The problem could not be identified at the local shop, so the car was towed to Audi dealer. Problem was found to be the generator. Have been waiting on replacement part for greater than 30 days, with no ETA as of today. Primary safety concern is that the car became undriveable within minutes of the red warning. Had I been on a highway or in heavy traffic, my car could have stalled in the middle of a busy roadway. Even if I had pulled off onto the shoulder, the risk to my family would have been quite high.

Our 2020 Audi Q7 (50,100 miles) suffered a catastrophic electrical failure while traveling on the freeway at 65+MPH. Suddenly the engine warning light went on, and then seconds later the entire interior lit up like a Christmas tree before it succumbed to a complete and catastrophic electrical failure. EVERYTHING failed – the car had zero power. No acceleration, brakes, steering, SOS, hazards / turn signals, brake lights, airbags, door locks, etc. My wife and child sat there in a steel box traveling at a high rate of speed while obstacles navigated around them; had they been hit, the air bags would not have deployed. This car nearly cost me my family. Audi replaced the alternator and the battery, and denied my buy-back claim because the incident hasn’t happened multiple times, and therefore doesn’t qualify for the lemon law. We continue to experience problems with the car – most recently: acceleration hesitation and recent warning lights saying 1. camera sensor failure (only to have them start working again), 2. tire pressure warnings (despite all the tire pressures being normal), and 3. warnings notifying me that lights are out (despite all lights operating normally). I believe Audi is underestimating the severity of the situation. We were fortunate that the initial failure on the freeway did not result in injuries or fatalities. I cannot fathom the idea of waiting for the vehicle to fail multiple times before taking it off the road, potentially putting lives at risk. The car has only been serviced at Audi dealerships. My family and I no longer feel safe in this car. While selling it is an option, I cannot, in good conscience, endanger someone else's life by not disclosing the vehicle's history and the well-known electrical defects Audi has.

Government / agencyIndexed Oct 9, 2026Source-linkedVerify source — NHTSA complaint #11652576

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 failures posed safety risks, including sudden loss of power while driving. Despite documented defects, Audi refused to take responsibility or perform proper diagnostics, resulting in continued safety hazards. I am formally requesting NHTSA to investigate the widespread issues affecting the 2020 Audi Q7, including the BSG system and excessive oil consumption leading to engine failure.” Additional Details: •Component/System Failure: The 48V Belt Starter Generator (BSG) and the engine failed. The vehicle is available for inspection upon request. •Safety Risks: The electrical failure at highway speeds caused a sudden loss of power. The engine failure posed a risk of the vehicle shutting down unexpectedly while driving. •Problem Confirmation: The Audi dealership confirmed the engine failure and acknowledged the presence of metal shavings in the oil, indicating severe internal damage. •Inspections: The vehicle has been inspected by the Audi dealership, and Audi representatives acknowledged the issue. •Warning Signs: The check engine light illuminated in January 2025. Additional symptoms included loud engine noise (‘tractor-like’) and increased oil consumption, which Audi dismissed.

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. Inconsistent Diagnosis: There was no mention of compressor damage during initial assessments. This late-stage discovery indicates negligence or potential additional damage during servicing. 2. Risky AC Activation: A technician attempted to clean the compromised AC compressor and activated the system, a procedure that is dangerous given the debris. This could lead to refrigerant leaks and electrical shorts. 3. Conflicting Statements: Audi Central Houston claims the compressor was previously damaged but also attempted to restore it. Such contradictions raise serious concerns about service integrity. 4. Certified Pre-Owned Credibility: The emergence of these costly issues questions the reliability guarantees of vehicles sold under Audi's Certified Pre-Owned program. Given that the vehicle began smoking shortly after being parked and had not undergone prior electrical work, I underscore the severe safety risks posed by potential electrical fires and undisclosed damage. These issues could endanger lives and property if not properly addressed. I strongly urge Audi USA and the NHTSA to investigate this matter for potential technical service bulletins or recalls, especially fo INFORMATION REDACTE

Government / agencyIndexed Oct 9, 2026Source-linkedVerify source — NHTSA complaint #11662153

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 safety risk from these coolant leaks involves: Coolant Ingestion: Coolant enters vacuum lines, mixes with oil (faulty PCV), or enters intake (failing intercoolers). Engine Malfunction: Ingestion causes misfires, drivability issues, and sudden power loss during operation. Catastrophic Engine Failure: Severe coolant ingestion can cause catastrophic engine failure, risking loss of control and collisions if the engine seizes/fails at speed. Sudden engine malfunction/failure while driving due to this systemic defect warrants immediate NHTSA investigation. Audi of America is aware. My contact (Mike, Ext. 43252) confirmed Audi is not addressing this widespread failure. Audi's inaction necessitates NHTSA intervention for consumer and road safety. Affected owners urge NHTSA to: Initiate a formal investigation into systemic coolant leak issues and component failures in EA839-equipped Audi vehicles. Assess the safety risks, including potential engine failure and loss of vehicle control. If warranted, issue a safety recall for affected vehicles to prevent accidents and injuries. Public safety is paramount. Evidence indicates a defect compromising vehicle safety and reliability. INFORMATION REDACTED
