2024 Audi Q4 E-Tron Recalls, Ratings & Complaints

Incident: May 5, 2025 · Filed: August 19, 2026

Within the first 6 months of owning the car my 2024 Audi Q4 E-tron premium door handle lock - unlock would not work and the car would intermittently not start. The dealership service replaced the 12-volt battery which has corrected the door handle lock-unlock issue; however, it has not corrected the no start problem. If I exit and enter the car multiple times it will eventually start (automatic seat start). The dealership service department cannot reproduce the problem therefore no solution has been made or offered. I have another appointment to leave the car 9/24/26 - due to additional starting concerns - on 9/11/26 my car would not start while at the dealership and a member of the service department witnessed the issue. On 9/17/26 - after multiple attempts to start the car and finally getting it into D - while initiating momentum and driving - the car shut down!! Luckily I was still in a parking lot and not on the highway!!

The high-voltage charging system has repeatedly malfunctioned. The vehicle intermittently displays a "Charging System Malfunction" warning and a message that only AC charging is possible, the charge-port indicator blinks green and then red, and the vehicle cannot be reliably charged. The vehicle and the affected charging components are available for inspection on request. Safety risk: because the vehicle cannot be dependably charged, it can be left without sufficient power to complete a trip, creating a risk of losing motive power and leaving the driver stranded, potentially on a roadway or in an unsafe location. The affected onboard charger is the subject of Audi Safety Recall 93FR (Onboard Charger with Integrated DC/DC-Converter) — a component the manufacturer has already identified as safety-related. As of 8/10/26, the fault has returned and I no longer consider the vehicle safe to rely on for normal driving. Reproduced and confirmed by a dealer: yes, on multiple occasions. On 06/03/2026 (~52,771 miles), Audi Tysons Corner recorded the "Charging System Malfunction / unable to charge / blinks green then red" complaint and performed a combined software update (ID.S 5.4.3, TSB 2080398). On 07/08/2026 (~54,673 miles), the same dealer recorded the "Charging System Malfunction / only AC charging possible" complaint, reported diagnostic fault P33E800 (charge socket / charge connector lock mechanical malfunction), and replaced the Connector Lock 1 Actuator (F498). The defect has since returned. Inspected by the manufacturer and others: the vehicle has been inspected and serviced only by Audi authorized dealers (Audi Tysons Corner and Audi Chantilly), including warranty and recall work, with diagnostic/GFF logs uploaded to Audi. On 10/13/2025 (~37,447 miles) Audi performed Safety Recall 93FR on the onboard charger, and the high-voltage charger was subsequently replaced under that recall. The vehicle has not been inspected by police or insurance. Repair invoices are avail

On three occasions, while in regenerative braking mode, my car failed to engage the brakes at low speeds. After pressing on the brake pedal for several seconds with no response, the wheels then locked completely - but only after the car had traveled had traveled around 30 feet. The dealer has inspected the car and has not been able to replicate the problem, so they say there is nothing they can do to correct it (although they are NOT saying that they don't believe me). There were no warning lights or messages about a failed system - the brakes just didn't work. This was very unnerving to me, and I don't see how I can drive the car without some corrective measures taken. I was fortunate that these incidents happened where no person or other car was nearby, but that was only luck. I reported the three incidents to the dealer, and brought the car in twice for them to inspect the car.

My Audi Q4 Etron has had this issue since it was new. The car has a sensor as part of the drivers seat. Once you sit in the seat the car turn on and you can start driving. The problem is if you make any movements, like turn to look back while your backing the car up or you reach over to pick up something off the passenger front seat the car will abruptly stop and turn off. It can take up to two minutes for the car to start again, twice i was left in the middle of a four lane intersection stranded. The second time it nearly caused an accident as multiple cares slammed their brakes. The dealership said that its a common complaint but there in nothing they can do, i was told to stay seated and to not move while driving. My wife also got stranded blocking an intersection and it also almost caused an accident, she was so scared that she will not drive the car or ride in it when im driving. Audi need to fix this before someone gets killed. I hope you can help.

On March 20, 2026, while my 2022 Audi Q4 e-tron (VIN: [XXX] ) was parked in my private garage at approximately 98% battery charge, I attempted to start the vehicle and experienced a complete electrical system failure. All electronic systems failed simultaneously, including: brake system (Brake System Failure warning displayed), parking brake sensor, traffic/charging system, power windows, and side view mirrors. The vehicle could not be placed into neutral. AAA was dispatched and the vehicle required a jump-start to the 12-volt auxiliary system before it could be moved. The vehicle was towed to Audi Beverly Hills for inspection. The dealership diagnosed the fault as: Control Module Main Processor Performance, Symptom Code 20079, per Technical Service Bulletin TSB 2074484/3. Per that TSB, the dealer was instructed by Audi of America to create a PSS (Pending Service Solution) record, erase the fault memory, and release the vehicle to me with no repair performed. The stated guidance from Audi of America to the dealer was to inform me that this is "an extremely infrequent fault" that is "being reviewed." No fix exists. No timeline for a fix has been provided. The vehicle was released to me with the underlying defect unresolved. This is a known, manufacturer-acknowledged defect with no current remedy. As a fully electric vehicle, the Q4 e-tron's braking and all safety systems are electronically dependent. A recurrence of this fault while driving presents an unreasonable safety risk. I am requesting NHTSA investigate whether TSB XXX /3 and Symptom Code 20079 warrant a formal safety recall. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am filing this complaint due to ongoing electronic and drivetrain malfunctions that may impact safe vehicle operation. AWD System Malfunction (Primary Safety Concern) The vehicle repeatedly displays four-wheel drive system malfunction warnings. I have brought the vehicle to the dealership three times for this same issue. The malfunction continues unresolved, raising concerns about traction, stability, and drivetrain reliability. Intermittent Entry Failure Biometric entry intermittently fails, forcing use of the key fob. This could delay access in emergency situations. Remote System Failures Remote vehicle functions (lock/unlock and climate control) operate inconsistently or fail entirely, often generating error messages. Audi has stated this is a system infrastructure issue with no current fix. Battery Power Inconsistency Although the battery indicates 100% charge, actual available power never reaches full output and drops shortly after driving. This creates uncertainty about vehicle performance and usable range. HUD Feature Does Not Perform as Advertised The head-up display does not show surrounding vehicle speeds as advertised, only colored indicators. This removes expected situational awareness information. Summary The vehicle exhibits repeated drivetrain warnings, electronic access failures, and inconsistent battery performance. These issues persist despite multiple service visits. I am requesting this complaint be formally recorded and investigated due to potential safety implications.

At least a dozen times, while accelerating from a complete stop, the car has experienced sudden unintended very hard braking without driver input. After very hard brake, car falls out of gear and needs to be restarted and put back in gear. -In clear, dry, temperate weather -Day and night -In drive and reverse -While accelerator engaged -Not touching brake pedal -No obstacles, pedestrians or vehicles present that would require braking -No warnings, alerts or messages on screen -Occurs randomly, nothing to indicate braking is needed -Most recent incident, on flat, familiar road, clear, temperate weather, no obstacles, car unexpectedly braked after accelerating from traffic light, fell out of gear and would not go back into gear for several minutes, resulting in near rear-end collision with multiple vehicles behind that did not expect sudden stop while accelerating. Eventually car would drive a short distance then hard brake, slip out of gear, not be able to drive. This was repeated 4 times before finally being able to drive without failure. -Audi inspected, could not reproduce the issue. It occurs very randomly, so it’s difficult to reproduce on demand. -No fault codes were found or stored -Dealer said without being able to reproduce it there was nothing to be done. I asked for TAC case to be opened for assistance. They strongly refused but eventually agreed. Case was opened but immediately rejected (within minutes). Later they said it was rejected for missing info, including location of incidents, which they never asked me for and I could have provided. Sudden random very hard braking and going into park while accelerating, then not being able to drive, with no warnings or fault codes, is a safety hazard.This has happened many times over a year. Other vehicles can crash into an unexpected stopped car in traffic. The last time I came within a millisecond of a major crash.

Car had electrical malfunction warning please contact costumer support and car died and zero damage to the body or the car. But the side air bags faulty went off. This car had a prior recall on file for same issues of car dying off and clerical problems. I got this car in September 2025 and had issue with it within the second month of having this car. I was not told there was a prior recall at all.

I was stopped in line at a drive through. The car started rolling (electric cars should not do that) so I tapped the brakes. The car started accelerating and I started braking hard and the car just sped up. Auto braking and collision warning did not kick in. The car slammed into the car parked in front of me and drove it forward about 10 feet. The driver has soft tissue injuries as do I. In the past, it has also lost acceleration while driving did not respond to the gas pedal. I frequently get warnings that the safety features are temporarily not working.

When vehicle is energized and in Neutral "gear" the vehicle makes no sound. I understand that federal safety standards indicate that when in this status, the vehicle should generate a sound so pedestrians can hear it. The vehicle does NOT generate a Vehicle Sound malfunction alert when this occurs (and it should). This condition is reproducible all the time. The service manager at Audi Dallas witnessed this condition and verified that it also occurred on a similar vehicle he had on the lot. I called NHTSA several months ago to report this, but I cannot find a record of it online so am repeating the report. If you do have a record of it, this is a redundant report.
