AUDI Complaints

1) The rear structural subframe (crossmember) has completely rotted, perforated, and failed due to severe corrosion. The factory-installed plastic underbody rock shields trapped road salt and water, causing the frame to rust from the inside out. The corrosion has spread, completely fusing and compromising the rear suspension mounting points and the rear differential brackets. The vehicle is fully available for physical inspection upon request. 2) My safety and the safety of others on the road was severely put at risk because the structural integrity of the rear suspension is completely compromised. The rusted metal anchors could snap under driving loads, causing a catastrophic rear suspension collapse, loss of vehicle control, or a high-speed wheel separation on the highway. 3) Yes. The structural failure was independently confirmed by two independent automotive service centers and an authorized Audi dealership service center (Audi Dallas). 4) Yes. An authorized Audi dealership representing the manufacturer physically inspected the vehicle on the lift during a goodwill evaluation. They confirmed the extensive structural damage and issued an official diagnostic repair quote of $20,873.78 to completely rebuild the failed rear subframe, effectively totaling the vehicle. 5) No. There were absolutely no dashboard warning lamps, electronic messages, or obvious driving symptoms prior to the inspection. Because the factory plastic underbody shields completely hidden the metal frame from view, the structural rot developed entirely out of sight until the vehicle was placed on a mechanical lift.

I am reporting a serious safety concern involving my 2017 Audi Q3 Premium Plus, VIN [XXX]. The vehicle is experiencing excessive engine oil consumption requiring frequent addition of oil. I reported the oil-consumption problem shortly after purchasing the vehicle. Audi Coral Springs recently diagnosed the vehicle and recommended substantial repairs. The dealership identified a crankcase breather/PCV condition causing oil to enter the intake system and also recommended replacement of the timing chain. The total recommended repairs are approximately $10,000. Audi's current diagnostic scan also identified multiple camshaft/timing-related engine fault codes, including P0011 (camshaft timing over-advanced/system performance), P0341 (camshaft position sensor range/performance), and P000A (camshaft position slow response). I am concerned about continuing to operate this vehicle because the engine is consuming oil at an abnormal rate. If the oil level or oil pressure becomes critically low while the vehicle is being driven, I am concerned about engine damage, engine failure or loss of power while driving and the potential for an engine-related fire. Of particular concern, while researching the vehicle's history I found a previous NHTSA complaint associated with this same VIN describing excessive oil consumption involving the pistons and/or piston rings and expressing concern that the condition could result in an engine fire. That complaint also described EPC/check-engine/low-oil-pressure warnings and stated that approximately $10,000 in repairs had been quoted. I am now experiencing excessive oil consumption in the same vehicle and same VIN, and I have also received an approximately $10,000 repair recommendation. I am requesting that NHTSA review this complaint together with the prior complaint associated with VIN [XXX] and determine whether the repeated excessive-oil-consumption condition in this vehicle. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am reporting an ongoing cooling-system/water-pump issue with my 2020 Audi Q8, approximately 75,000 miles. The problem began when the vehicle repeatedly displayed a low-coolant warning. Inspection confirmed the coolant level was very low and a significant problem involving the coolant pump/vacuum system was diagnosed. The water pump was subsequently replaced. After the repair, the vehicle initially appeared normal, but problems continued. I experienced engine sputtering/rough running and the vehicle felt as though it might stall while stopped at a traffic light. A Drive System Malfunction/check-engine warning appeared, and cruise control/driver-assistance functions became unavailable. The check-engine light has continued to return intermittently. There was also an issue with a loose cap following the water-pump repair, which was corrected. Despite this, the low-coolant warning later returned and the coolant reservoir was again confirmed to be low. Coolant was added and the vehicle was returned to the repair facility to locate a leak. The shop kept the vehicle for several days and ran it for approximately two hours while inspecting it but could not reproduce or locate a coolant leak. The check-engine light went out during testing but returned shortly after the vehicle was picked up and driven normally. A sensor was also replaced based on a diagnostic code, but the check-engine light returned afterward. I have now spent more than $3,000 attempting to correct these issues, yet the cause of the recurring coolant loss and warning lights has not been determined. I am concerned that this may represent a recurring defect involving the water pump/cooling or related vacuum-control system. My primary safety concern is the possibility of unexpected coolant loss, overheating, engine malfunction, reduced power, or stalling while driving. I am requesting that this complaint be documented and investigated for similar incidents involving 2020 Audi Q8 vehicles.

Electrical system failure due to water in the spare tire & battery well, purchased key fob, 2 auto batteries unable to program fob due to non compatible 1st battery, info display contact dealer, had the water extracted, there were no prior indicators of an upcoming issue until the morning of May 22,2026 when my vehicle wouldn't start so I called roadside assistance for a boost. The key symbol is constant on display now, after over 2mos @the dealer, made several calls to Audi Corp, Audi. com, Audi USA., Consumer Protection, Texas Lemon law , it was shown to have an active recall. I was advised to contact my insurance company, which was denied seems as though no resolve for an actual ongoing Audi issue. I'd hate to be driving & the vehicle comes to an abrupt stop & put lives in danger from a known ongoing recall issue by Audi. Thanks in advance for your attention to this matter. Regards,

On 8/3/26, my 2021 Audi Q5 began throwing numerous different malfunction/error alerts and the engine turned off while driving after a bottle of water had partially spilled onto our backseat behind the drivers side. The vehicle was towed to a nearby mechanic who determined that liquid damaged the gateway control module located under the backseat of the vehicle, as the gateway control module is placed in a "protective cover" (an unsealed plastic bag) and that bag visibly had liquid inside of it. We had immediately contacted Audi upon learning of this issue and decided not to move forward with any repairs, but to instead pay out of pocket to have it towed 70 miles to Audi/where we originally purchased the vehicle. This "protective cover" the control module was placed inside was completed as a recall service repair on our vehicle in April of 2022 due to a NHTSA recall announced in December 2021 regarding safety issues in these control modules failing from liquid spills on the backseat. We contacted Audi, explained that liquid had spilled in our backseat and entered the "protective cover" and damaged the control module. They agreed to inspect our vehicle to determine if the "protective cover" had been insufficiently installed. We paid out of pocket to have it towed to the dealership where it took them 6 days to determine the gateway control module is damaged (we had already explained this to them). Although liquid was found in the "protective cover" of this gateway control module, the dealership claims it was installed sufficiently. Upon looking into this matter further, there are numerous complaints of this exact issue (water entering and damaging the gateway control module from a liquid spill on the backseat, even with the "protective cover") on the NHTSA website, as well as a previous class action lawsuit settled out of court in regards to this EXACT issue. THE PRIOR RECALL REPAIR DOES NOT FIX THE SAFETY HAZARD AS STATED IN THE OFFICIAL NHTSA RECALL REPORT.

The clutch does not engage properly and the vehicle makes a grinding noise when starting to move and while making right and left turns.

I purchased the car in October, 2023. The problem first happened in October, 2025 and not happened just once. The vehicle breaks unnecessarily and violently without any warning. Additionally the pre-sense collision indicator light displays when there is no apparent person, vehicle or object in the vicinity of the vehicle. The abrupt breaking is the most concerning since it has happened multiple times and at one point, I was in the middle of an intersection making a left turn into a shopping center on a busy street. There were cars coming in the distance but far enough away that it should not have stopped. Luckily they were far enough away that they could see me stopped because I could not get the car to move until I put the car in park and then back into drive. Additionally, there were cars behind me which could have easily rear ended me due to the unexplained abrupt stop. I have taken the vehicle to the dealer for the issue and they were not able to recreate the problem. They told me they changed some settings on the sensors and to keep the outside sensors clean. I keep my car very clean and do not live in an area where debris would accumulated on the sensors to create a problem. The adjustments they made did not help and I still experience the problems. I will be taking it back to the dealer again to report it again to them. At this point I do not feel safe driving the car and will express that to the dealer when I take it in.

Vehicle performs a complete stop in the middle of a drive on the freeway. I loose sight of where I am going due to this sudden break, without knowing the UNKNOWN OF WHAT WILL HAPPEN. The vehicle has been inspected by Audi dealership over four times for this issue, in which they are not resolving this problem and stating nothing has been discovered by the scanner. The only message followed by the immediate breaking is ,"Emergency Assist: Cancelled". I have been denied a buyback two times because it's not considered a "repair". They are not taking my situation and safety concern seriously and I am hopeless.

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!!

While driving at about 60 mph on highway, several systems in the car failed without prior warning. The message on dashboard said Catastrophic Electric System Failure. Brakes would not work for a moment and then started working. All windows came down and went up on their own. No lights were working. No blinkers or side lights were working. With a lot of difficulty and hand signals moved to the hard shoulder. The engine would not turn off for several minutes and turned off after multiple attempts. Audi tested the vehicle and found multiple DTC's in various modules - all sporadic and happened at the same time. Audi did software update and is waiting for another software update to be approved by EPA. The Director of Service at Audi thinks the failure may be also due to a problem with hardware/battery. He said he does not trust the vehicle in its current state and the vehicle is presently grounded at the dealership.
