AUDI Complaints

Water intrusion from sunroof floods electronics modules and shorting out, making the car unoperable

The contact owns a 2021 Audi Q8. The contact stated that while driving at an undisclosed speed in the rain, the automatic braking system sensors engaged. There was an abnormal sputtering sound coming from the vehicle. The driver believed that the vehicle had struck an object. The vehicle was taken back to the local dealer, who was unable to repair the sensor, and the failure recurred. The manufacturer was contacted and filed a claim. The approximate failure mileage was 8,600.

On five separate occasions across two separate drivers, we have experienced a partial brake failure in this vehicle. We strongly believe this to be a software defect and not a mechanical fault. On the e-Tron, the first portion of the brake pedal swing typically activates the regenerative braking. About mid-way through pressing the pedal, it changes to "real" mechanical brakes. When this brake failure occurs, we get to that midway point and the car lets off the regenerative braking but does NOT apply the mechanical brakes, so the end result is that the more you press the brake pedal, the less it works. Three of these five occasions occurred in one day, so by the time the third time came around, I was really paying attention and I'm very confident this wasn't driver error. In at least one case, the only reason that a crash was avoided is because the automatic braking / forward collision system activated. The vehicle has been inspected by a dealer, who found "No Repairs Recommended". We requested an update to the ABS module software, as this software update is known to resolve multiple other problems with the braking system (see TSBs 2072977, 2061906) but we were denied the update.

Hi My name is [XXX] and I have an 2014 Audi A4 that has been consuming to much oil ever since I bought it . I see the vehicles contained defective pistons that caused excessive oil consumption. Can you please help with this ? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Since 2021-2022 I have had several issues with my reservoir tank. This tank holds my coolant and has leaked continuously. They had a settlement for this problem but omitted the a3. I paid Audi dealership $ 1,600.00 to fix the problem a few years ago and have been having the same problem ever since. A few months after I paid for this problem Audi had a settlement for the reservoir tank and I was denied reimbursement because I owned a a3 and a3’s were not included in the settlement but a3 ‘s still had the reservoir problem as well. I contacted Audi USA on several occasions and still have been disregarded but Audi USA wants you to pay for the diagnostic first at the dealership just for them to even look at the immediate problem. I just contacted Audi USA again 1/29/25 because now I have to put my car in the shop again to get it fixed but the coolant constantly leaks and Audi service shop wants me to pay for it and I feel that I should not have to pay for (their )problem again and the same problem over and over. At this point the coolant is pouring out like water and I must get my car to the shop immediately because the engine light comes on stating no coolant running hot and this is how the Audi cars catch on fire.Please investigate this !!!! I refuse to give Audi any more of my money when they should be held responsible. I can’t find my receipt of date and amount paid but I can get this info from the dealership. I’m tired of going in a circle with this same car issue. I want my car fix and my settlement reimbursement.

An Electrical Malfunction has caused several safety issues causing the car engine to idle and have "drive system malfunction" The warning system being displays on the dashboard has show not only cooling issues but issues relating to the brakes and overall engine making the car unsafe to drive. The Audi Pre-sense system engages the brakes while driving a varies fast speeds usually while on the highway.

2018 Audi Q5 comfort System Control Module is faulty due to corrosion from water and or humidity. No incidents have occurred with my vehicle that has less than 70k miles. I purchased the vehicle as a certified pre-owned with 7700 miles on the car. The dealership claims that outside forces have cause the module to corrode and that I am responsible for the 10k payment to replace and/or repair.

Ecu Malfunction leading to Cooling system malfunction The car after idling more than 30 min with the A/C off has a "drive system malfunction". The warning displays on the dash and the engine runs violently rough until the car shuts itself off. The Audi has done this several times, though not while driving. This problem creates a lot of heat in the engine bay and has led to a problem in my cooling system pipes, causing multiple points of piping to burst. The coolant expansion tank also warped and leaks, as well as the upper radiator hose. The problem with safety is the car will spray coolant onto the wheel well making the brakes less effective. This problem, which seemed to arise from the car ecu overheating during idle, could cause an undesirable effect while driving, potentially leading to an accident. The other issue is that the car is overheating due to a compromised cooling system that leaks coolant fluid. This may damage the engine and other engine bay components. The warning sign and first instance i can recall the "drive system malfunction" happening was in February of last year, a month after purchase. The cooling system started leaking profusely 4 months after the first "drive system malfunction".

There currently exists a recall (24T-009) on the Continental ProContact GX AO 255/35R19 96H XL tire which was the OEM tire on some MY21+ Audi A4/A5s. The recall was the result of the compound used on the inner and outer edges improperly dissipating heat, resulting in premature wear, and belt breakage. I have a 2023 Audi A4, [XXX] which has the OE Continental ProContact GX AO 245/40R18 97H XL on it, and at 26,500 miles on the vehicle, all 4 of the tires require replacement due to significant wear on the inner and outer edges. All maintenance and service intervals were completed early or on time by the certified Audi Dealer. All 4 tires show normal and safe tread wear with the exception of the inner and outer edges. There are no known mechanical defects or issues with the vehicle, and the ADAS system functions properly and without issue, so there is certainly no alignment issue significant enough for a system fault. I am concerned that the Continental ProContact GX AO 245/40R18 97H XL tires suffer from the same defect as those in NHTSA recall 24T-009 and that if not replaced due to premature wear, will create a risk of injury and death.
