AUDI Complaints

The car has always (including during warranty period) required addition of engine oil in between scheduled maintenance interval, and problem got worse as function of age/miles. Audi has diagnosed this issue and it has been determined that the engine consumes excessive oil and requires new piston skirt. The cost of the labor is not something Audi is willing to pay for and there is a class action lawsuit. Audi has sent an email/letter to certain owners of the vehicle. My VIN for some reason wasn't included but now Audi has verified, but not willing to pay for the cost to replace the engine or fix it.

Front suspension ball joint failure occurred while driving approximately 70 mph on an interstate highway, resulting in sudden loss of vehicle control and requiring immediate emergency response. The vehicle is a 2023 Audi e-tron A5. Two weeks prior to the sudden failure, an Audi dealership inspected the same front corner of the vehicle following earlier damage and stated that the front suspension and wheel components were safe and the vehicle was fit to drive, replaced the rear right tire and recommended replacing the rear wheel housing after not being able to get the full car alignment to spec. I told them I wanted to defer that service until later in February unless it was catastrophic when we discussed the findings. They told me that the car was safe to drive and proceeded with the wheel alignment and replacement on the rear. The ball joint failure was catastrophic and presents a serious safety concern, particularly given the recent dealer inspection and the short time between inspection and failure. Warranty coverage was later denied by the dealership, despite having just inspected the car for damage and claimed that the failure of the front ball joint was caused by deferring the rear wheel housing service. I am submitting this complaint due to the safety implications of a suspension component failure at highway speed and concern that the defect may have existed and should have been detected during the prior inspection.

CATASTROPHIC ELECTRICAL FAILURE - SMOKE IN CABIN While driving with passengers, dashboard displayed "ELECTRICAL FAILURE - PULL OVER WHEN SAFE" followed by loud explosive POP and cabin filled with SMOKE. ROOT CAUSE: Prior undisclosed collision damage. Dealer (Morrie's Golden Valley Cadillac) removed front bumper in June 2025 (Repair Order #78683), then sold vehicle as "no accidents" in August 2025. Subsequent inspection revealed cut wiring and improper repairs (Invoice #94609). CURRENT STATUS: Vehicle inoperable 3+ months. Audi corporate technicians have repaired major problem however vehicle still has charging issues that happened right before the catastrophic failure unable to repair. SAFETY CONCERN: Smoke-filled cabin endangered occupants. Potential fire hazard.

The high-voltage charging flap assembly (Part 4KE810001) has failed, preventing the charge door from latching. Notably, this failure (DTC P31D000) occurred within 7 days of the vehicle being serviced at Audi Burlingame for a high-voltage battery software recall. This presents three safety hazards: 1. Driver Distraction: Triggers a continuous auditory chime and 'Warning! Please check the charging unit cover' message every 10 seconds. It cannot be silenced, creating a severe, persistent distraction. 2. Unintended Deployment: At highway speeds, the unlatched flap opens/flaps due to aerodynamics, creating a visual obstruction and distraction for the driver and traffic. 3. Moisture Ingress: Failure to seal the port exposes the high-voltage interface to pressurized rain/road spray. Per NHTSA 19V434 (Recall 93E8) regarding moisture ingress in this system, this failure represents a recurrence of a known safety risk. Evidence of Defect: Audi has iterated through three versions of this part (4KE810001, B, and C), confirming an inherent design flaw. This component is specifically identified in Service Campaign 93H6 for proactive replacement. Despite this, and the failure occurring immediately after recall service 93V2 on October 1st 2025, Audi Burlingame denied a 'goodwill' repair and quoted $1,100+ for a part already internally flagged as defective. Repair declined due to cost; safety hazard remains active. I am requesting that the NHTSA open an investigation into this component failure. Thank you,

* Passenger front Seat wiring harness corrosion and failure due to water ingress due to leaking web plate in the longitudinal member on passenger side. Water ingress in passenger compartment caused electrical failure and black mold to grow in the interior carpet and seat rails as well as in an electrical well in the floor board. *Black mold and mildew can cause long term health risks to those persons exposed especially if one didn’t know the mold was present. *The vehicle has been repaired at VW dealership in Missoula, MT. Service tech couldn’t figure where the water was coming from. Finally did research to find an Audi TSB 2059792/5 with the cause and remedy. *Recently Purchased this car and later found the seat not working. The VW dealership/service found the electrical corrosion and mold. Mold was not visible until the seat was moved. Mold was extensive throughout the passenger side under the seat - spread and growing under the carpet, insulation and in the electrical well in the floor board. Pictures attached - tech write up also available upon request. No warning lights were present. ** Audi put out a TSB (Tech Service Bulletin) in 2023 and repaired the cars under warranty - assume this was a wide spread issue for a TSB to be issued and for Audi to manufacture parts to fix the problem. Mold can have serious long term consequences to anyone exposed. I believe Audi should have done a recall for safety reasons. I just bought the car on 1/10/26 used with under 40,000 miles. Carfax or other research did not turn up a recall. I have sent a letter to Audi of America detailing the problem, referencing the TSB and asking them to cover the cost of repair as they had covered the cost on vehicles under warranty. This car is just out of the 5 year warranty but has only 40,000 miles on it. No recall was issued that I can find. Any help you render would be appreciated. Mold exposure is serious if not immediate.

SoS emergency call malfunction. Besides transmission or engine mounting shakes on idle positions car still 6800 miles

My vehicle is a 2022 Audi SQ7. On Feb 4th 2026 at 22,100 miles dealer determined that the water pump is leaking and quoted ~$4400 for replacement. Stating that my warranty expired less than 2 month ago on Dec 6th 2025. After reading multiple online resources it looks like it's a very common problem on this vehicle but it was not included in a settlement(Civil Action No. 2:21-cv-11251-MCA-MF) for some reason. I wanted to file this complaint so nhtsa could look into the water pump issue with 4.0 engines EA825 from Audi

2022 Audi S3 (8Y), ~35,000 miles. Vehicle developed “Gear selector malfunction. You may continue driving.” Dealer stated failure would eventually leave vehicle stranded. Gear selector replaced under partial goodwill. Immediately afterward, vehicle began experiencing communication faults U123100 and U123000 gateway module. Car reported fault 1/20 under dealership possession. Car was picked up by me 1/21 Since repair, GPS location is severely inaccurate (initially ~300 ft offset, escalating to over 50 miles, including placing vehicle in Atlantic Ocean). Vehicle displays incorrect speed limits while driving (35 MPH shown on 70 MPH highway). Constant warning chimes: “Traffic sign recognition unavailable.” These faults affect driver information systems and safety features while driving. Issues are persistent and worsening. Concerned about electronic network failure and loss of vehicle control or situational awareness. Clear progressive ADAS failure.

Piston slap issues. The manufacturer is aware of the engine failure issues. They extended the engine warranty coverage from 50k to 80k miles knowing that the engine piston slap is an extreme issue but they won’t issue a total and complete recall. Owners have to identify that issue and have to specifically bring it in to have it bore scoped. If an owner isn’t aware of the noise and goes over the 80k miles then they are not held responsible for the complete and utter engine destruction.

Control module located under rear seat became slightly wet from spilled liquid, and failed. Engine and electrical failure as a result of control module failure. Audi refuses to cover damages as warranty period is over. Vehicle design is defective.
