AUDI Complaints

Complete Engine Failure - Audible Engine Knock Noise. Bank 2 Knock Sensor Faults stored & recorded at Audi of Hoffman Estates. Worked with Audi Of Amercia where they denied any wrongdoing or know issues. Bore socped engine at an independent shop & confirmed the cyclinder 6 bore was scored due to picton failure. Paid for a USED engine replacement & install out of my pocket on 8/5/2025 $4,655.57 Install Charge $6,760.49 Used Engine Cost On 9/8/2025 I recieved a letter in the mail from Auid Of America Outling a Piston Skirt Limited Warranty Extension. I reached out to Audi of Amercia the following day, outlined my experiece and was unaware how at no time during my phone calls & emails with Audi of America was a piston skirt issue never discussed. I had the bear the cost of engine replacement out of pocket as during the time frame of failure and per Audi - The repalcement engine was on "intergalactic backorder". When I reached out to Audi of America to discuss reimbursement my claim was denied due to "incompitible or aftermarket parts", which they then changed there response and said it was due to "used" parts being installed. The contact at Audi Of America was Rebecca Gray - To this date she is no longer returning phone calls or emails, also had my email address blocked from the Audi Server at one point. When I reached out to a high up executive via text message, I didn't recieve a response but my email was unblocked in short order. Audi has tried to hide the extent of the piston skirt issue from its consumers & NHTSA. This needs to be stopped.

In 4/2024 car wouldn’t start. Took to Audi for new battery and was told Water pump failed so it was replaced with delays. In 3/2025 noticed no heat and car took a long time to warm up. Took back to dealership replaced thermostat. Still no heat so I was told ok to drive but need to flush heater core to fix heat issue for $3500. Started my car on 8/14/2025 had multiple lights come on dash (lights, brake, TPMs, epc, and brake fluid) so I turned off. Took to mechanic for inspection told something strange different codes instructed to take to dealer. On 10/8/2025 took back to Audi for evaluation and first they stated my fuse box panel was slightly melted couldn’t code read. Ordered part, 2 weeks, and would be $2,000 for repairs. On 10/15/2025 they state I have Coolant migration from over flow and it would be $35,000 for repairs which exceeds vehicle worth to buy another. Have not experienced any coolant loss since water pump failed and was replaced in 2024.

Drive system malfunction message appeared after starting ignition at 6am before heading to work. Turned car off immediately and took another vehicle to work.

Water pump failed coolant leaked all over the vehicle five years old and a $7500 repair vacuum seals and most of the engine is damaged from the coolant. I have the video from the dealership but can’t upload

I am submitting this complaint regarding a serious safety issue I experienced with my vehicle. Shortly after starting to drive, about 2 miles from my home, while traveling at approximately 25 mph, the vehicle suddenly began to shake violently and came to a complete stop at the intersection of Crescent Street and Astoria Boulevard. At that moment, I lost all control over the steering wheel—it completely locked up. The dashboard displayed the message: “Drive System Malfunction – Contact Service.” These diagnostic trouble codes (DTCs) appeared: •P2179 •P025C •P0087 •P0306 This incident posed a major safety risk, as I was unable to steer or move the vehicle in a high-traffic area. I am very concerned that this could happen again or to other drivers under more dangerous conditions. Please investigate this matter as it may indicate a serious defect that could affect others.

Our Audi has 13k miles. We noticed large chunks of rubber pulling away on the treads with pieces large enough to put our finger into. The dealer says they have seen this problem before with this tire

The pcv oil separator has failed and is making a whistling sound. From researching this issue it is widely known and an investigation shows it is caused in relation to a recall for the oil strainer that was done on this vehicle. I called audi dealership and they said this is not an open recall, however it seems this is exactly what caused it.

Car displayed a warning sign that safety system malfunctioned. Airbag indicator showed “passenger airbag off”. This error occurred sporadically and for a limited amount of time. It also kept sensing that passenger seat was occupied when it wasn’t. From what I understand , the issue is related to passenger side PODS sensor.

Part #: 4h0907217fx which is a windshield camera has stopped working and Audi has no solution to repair it. I have been without Cruise control, ABS error codes for 2 years. Please help.

The Gateway control module failed in September 2025 on my 2021 Audi Q5. Vehicle error messages included the following failures: Cruise control, Parking brake, transmission, brakes, and steering, windows rolled down, seats moved, dash and MMI black followed by a sudden loss of power, narrowly avoiding an accident (kids in car). Would not restart. Diagnosis by Audi dealer was that the Gateway control module got wet and needed to be replaced. This is Recall 90S9 from 2021 that was “repaired” in March 2022 by covering the module with a plastic bag. This proved an insufficient repair backed up by a class action lawsuit filed in January 2022 titled Gioffe, et al. v. Volkswagen Group of America, Inc., et al. (Case No. 1:22-cv-00193). I reached out to Audi USA to request a Goodwill repair which was my only available recourse given that the recall had been completed and closed. After 5 days the Regional Manager denied my request even after I emphasized the safety risk associated with this catastrophic failure as well as the recall in 2021 and class action suit filed in 2022. I paid $1485.33 to re-repair the recall. Driving home from repair my vehicle alerted me to the following messages: Vehicle starting system: malfunction! Please contact Service, and Audi pre-sense: currently limited. See owner’s manual. An OBD scan alerted 7 more codes: 1. Steering Assistance ID 44 (Terminal 30 Open circuit), 2. Central Electrics ID 09 (Garage door opener transmitter no communication), 3. Gateway ID 19 Control module for emergency call module and communication unit no communication, 4. Ethernet Notrufmodul keine Kommunikation, 5. Ethernet databus branch 1 No communication, 6. Multimedia ID SF Function restriction due to communication interruption, 7. Driver Assistance ID A5 Dynamic calibration Function limitation due to limit value exceedance.I reached out to the dealership that performed the service and was told that those are “ghost codes” and nothing to do with the work performed.
