On March 22, 2026, my Check Engine light came on while driving my 2022 Audi A3. Prior to this, I had been noticing a slight jerk when accelerating from a stop. Because Audi dealerships charge approximately $250 just to read diagnostic codes, I went to Discount Auto Parts, where they retrieved code P27F500 — indicating the gear shift lock solenoid is stuck in the open position. I then contacted my Audi dealership and asked directly whether this required a software update or if the gear selector was physically failing. They refused to give me a straight answer. I separately spoke with an Audi service technician who confirmed that the 2022 Audi A3 is well known to have this exact issue. My own research confirmed that this defect is widespread across both Audi and Volkswagen vehicles sharing the same platform. My vehicle is only 3 years old with no history of abuse or neglect. Repair estimates for this known manufacturer defect range from $1,500 to $2,000, which is unacceptable for a defect that appears to be a manufacturing issue, not owner caused damage. I am requesting that NHTSA investigate this as a potential safety defect and consider requiring Audi to issue a recall or provide repairs at no cost to affected owners.

Blown turbo with propeller broken off lodged into the pre-catalytic converter, which caused damage to the catalytic converter/exhaust requiring a new turbo and a complete new catalytic converter and exhaust system. They also found major oil leaking from the upper timing cover gaskets, which I later found documented on the accounting service record as not repaired at that time few months from my purchase. These known engine damages were a major contributor to the engine failures that I’m faced with today. Oil starvation from known oil leaks, damaged gaskets, and failing parts caused oil starvation of the turbo, constant overheating with coolant and oil problems since purchasing the car and which ultimately froze the turbo and snapped the propeller. I’m still struggling without an operating vehicle for over a year, and trying to afford these expensive repairs, which should’ve been covered under the 15 year PZEV warranty and/or recalls of these known parts failures. It was at the dealership in plenty of time for the SMOG certification, which was the sole reason for the appointment and it being at AudiSD, which they refused to do. These are extremely expensive repairs, these are known issues with several class action lawsuits and recalls behind them, yet they simply refuse to take ownership, deny any support, and making excuses for their lack of responsibility. I asked several times for them to do the right thing, take the car back and refund my money or give me an equivalent car to what I was promised when I purchased it, they refused and no management has been involved. I deserve to be compensated for my time over the last several years dealing with these repeated issues, compensation for all the parts I have been forced to buy, refunded the amounts I’ve paid for technicians to truly diagnose the problem and for the repairs I’ve yet to be able to afford, as well as the towing and other charges I have incurred as a result of purchasing this vehicle from AudiSD
NHTSA complaint #11723149 — an unverified report by a vehicle owner.
The contact owns a 2019 Audi A3. The contact stated that while driving 65 MPH for a 50-mile trip, the message "Transmission Failure" displayed, and the check engine warning light illuminated. The transmission then inadvertently switched from automatic to manual transmission mode and became stuck in second gear. Additionally, the vehicle jerked and decelerated to 35 MPH while driving. The contact activated the hazard lights before pulling over to the right shoulder to turn off the vehicle. The vehicle was restarted, but the failure persisted. The contact stated that the vehicle was consuming an excessive amount of fuel very quickly. The contact was able to drive to the destination. The vehicle was taken to an independent mechanic, who retrieved DTC: P173500 (Electrical Malfunction with the Position Sensor for Clutch 1 in the Transmission). The vehicle was then taken to the dealer, but no cause for the failure was found. The contact then drove the vehicle for a long distance at high speeds and was able to duplicate the failure. The vehicle was taken back to the dealer, who determined that the mechatronic hardware, DSG transmission cover, gasket, and fluid needed to be replaced. The vehicle was not repaired. The contact related the failure to Technical Service Bulletin: 2058504/1 (Transmission malfunction, DTC P173500 and/or P173600 stored in the TCM). The manufacturer was made aware of the failure, but informed the contact that the VIN was not included in the Technical Service Bulletin. The failure mileage was approximately 34,500.

My 2015 Audi A3 1.8T is experiencing the exact same failure symptoms and operational hazards as those described in Audi’s own Warranty Extension U49, which covers certain 2017 and 2018 Audi A3 and A3 Cabriolet 2.0 TFSI models. According to Audi’s bulletin, vehicles with faulty mechatronic units are eligible for replacement under an extended warranty due to safety concerns — sudden loss of drive, vehicle being stuck in neutral, and PRNDS flashing while in traffic. My vehicle is now exhibiting these identical symptoms: (1) Sudden disengagement of all gears while driving when it tries to go to fourth gear. At this point, there is a (2) flashing PRNDS indicator and “Reverse Gear Not Available” message. (3) Loss of ability to accelerate in moving traffic, requiring emergency maneuvers, and halting traffic. (4) Temporary restoration of function after shutting off and restarting the engine, only for the problem to happen again. (5) Check Engine Light. This is a serious safety hazard that puts both the driver and other road users at risk. The only reason my vehicle is excluded from the coverage appears to be its model year (2015), despite the fact that the mechatronic unit and failure mode are identical to the covered 2017–2018 vehicles. I believe Audi overlooked this issue in other year models and, as such, I respectfully request that the NHTSA investigate why Audi is limiting this safety-related repair to only certain VIN ranges and model years, when vehicles just a couple of years older are exhibiting the exact same dangerous defect. A sudden loss of propulsion at highway speeds is a serious risk that warrants broader manufacturer accountability. The company should fix this issue as soon as possible.

I was driving on the freeway at 60 mph when I received a warning code of a transmission problem. The code said the car was driveable but I should take it in for service. About 1-2 minutes after that the car lost all power. Unfortunately I broke down in the left lane in a construction zone without a shoulder. The state patrol had to temporarily shut down all three lanes of the highway to push me out of the traffic lane I was blocking. That was unsafe for me and for the state patrol and for the tow truck driver. The car was up to date on all recommended service, had been acting normally until the moment it failed, had not given me any warnings and is only 6 years old. I had the car towed to the dealer and the dealer reported that the Mechatronic unit (transmission computer) failed. Replacing the Mechatronic took a week and cost $5000.

Car has 50,000 miles and vehicle has a bulletin on the vehicle from Audi, where the vehicle goes into limp mode and only shift through certain gears, rendering the vehicle, unable to drive and creating a safety hazard due to the fact that it can’t drive at Highway speed and or jolt and skips gears. Code for the P173600 known issue by Audi, went into mode while merging onto freeway and a lost control of vehicle.

NHTSA complaint #11644062 — an unverified report by a vehicle owner.
The **mechatronic unit** (integrated into the S-Tronic dual-clutch transmission) is the primary component that fails. This unit controls gear shifts, clutch engagement, and hydraulic pressure within the transmission. Common failure points include: - Internal electronic control module (ECU) faults. - Malfunctioning solenoids or pressure valves. - Software glitches or calibration errors. **2. Safety Risks** Mechatronic failure poses significant safety risks: - **Erratic Gear Shifts**: Sudden jerks, delayed engagement, or refusal to shift gears could lead to loss of vehicle control, especially in traffic or during overtaking . - **Limp Mode**: The transmission may default to a single gear (e.g., 3rd gear), severely limiting acceleration and braking responsiveness . - **Complete Gear Loss**: Loss of reverse or multiple forward gears increases collision risks during parking or low-speed maneuvers . --- **3. Confirmation by Dealers/Service Centers** Dealers and independent specialists can reproduce and confirm the issue through: - **Diagnostic Scans**: Fault codes like "implausible gear ratio," "valve electrical faults," or "clutch adaptation limits" often indicate mechatronic failure . - **Physical Testing**: Symptoms such as harsh shifting, RPM fluctuations, or transmission warnings (e.g., flashing PRNDS lights) are observable during test drives . - Audi has issued **Technical Service Bulletins (TSBs)** for related transmission issues, though the 2016 A3 e-tron’s mechatronic unit isn’t part of a formal recall.

Car throws P2884 and the internal combustion motor will not start. The issue is gone into detail here: [XXX] recommendation is swapping out mechatronic unit for the upgraded unit. Since the unit is prone to failure this really should be a recall. It happens on all cars 2016/2017 years right around 60k miles.

About once per month my car will rev when the accelerator is pushed but the car will not proceed. On MULTIPLE occasions this has put the SAFETY of myself and other road users at SIGNIFICANT RISK. This is because I'll be attempting to pull into traffic and the car will FAIL TO PROCEED. This is a known issue documented by Audi in TSB # [XXX] [XXX] ). I've described the issue before to my dealership but only found out about the fix myself via researching on NHTSA's site. Further, this should CLEARLY BE A RECALL - the vehicle does not move when it is needed. Audi should not be charging customers for this update and it should be applied to ALL effected vehicles. Happy to provide any additional information needed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2023 Audi A3 with less than 3,000 miles completely stopped in the middle of a highway in Saugerties, New York. 4 hours away from home. I had my dog and my little sister with me and in the freezing pouring rain we had to get out and redirect traffic/ try to find help. I called Roadside assistance. They never came on [XXX] and didn't call back till 10pm to say they couldn't get to us because of the 8 inch snow storm. We had no heat because the car would not turn back on. 5 Ubers/ 3 lyfts and all taxis didn't come. Finally 1 uber came and took us to a nearby camp site where they allowed pitbull dogs. The next day, I had to call over 60 times to get someone to just tow my car to Audi Albany. Audi Albany would not drive me a loaner car because it was an hour away. With a lot of arguing Audi roadside/tow services finally allowed me to drive with the tow truck driver to Audi Albany. They gave me a loaner but said I had to book another hotel night because I was not allowed to drive the loaner back to my home yet. I was stuck in Saugerties NY for 2 nights 3 days. We both got sick from Sunday waiting for roadside assistance for over 5 hours. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The high voltage battery no longer charges to full. Only 7 out of 8 possible indicator bars are illuminated, the car now only shows 17-20 miles available. When I purchased the car 3 years ago, it showed 28-29 miles available. Car was at Audi dealership, got tested, Audi says it's within tolerance. I disagree, 30% to 40% of the capacity is lost so far. There are many more owners that are reporting the same issue on the Facebook Audi A3 group.

Transmission module! Started jerking when switching gears, to not switching gears at all and this happened while driving so I was on the road stalled with no gear changes! Car is inoperable, due to this and it’s still being paid for yet not able to be driven from practically the day I bought it! The manufacturer knows this is an issue and we are still out here in unsafe non gear changing cars! Very dangerous

I was entering the interstate and accelerating to merge with the traffic. When I reached about 70 mph the car stalled and a message appeared, transmission faulty, no reverse, safe to continue to drive. The car was drivable at a low speed and a high rpm. After having it towed to an Audi dealership, I was informed that the transmission would need to be replaced. According to the dealership, the mechatronic unit was faulty due to an unknown short in the transmission.

“Transmission Malfunction/no reverse gear. Okay to continue driving” comes on constantly the past 2 years now. I’ve only had this vehicle 3 years. Yes , it is available for inspection. This puts my safety and the safety of my other passengers at risk because my vehicle will abruptly slow down in fast flowing traffic and it will uncontrollably accelerate when it’s time to come to complete stops. A local mechanic used a sensor to check for faulty defects and confirmed that my transmission is having sensor issues. There has never been any warning lamps , regarding this problem. There have been no prior warning messages regarding this issue. I purchased this vehicle from Audi Dealership in Van Nuys, CA in November 2020. I have had this vehicle less than 3 years & as of now , it has less than 35,000 miles on it.

This concerns a recall issued. Audi issued a recall/reimbursement for transmission failure. Mine failed. Car stopped in the middle of roadway. I had transmission repaired before recall was issued. I have attempeted reimbursement and am denied by audi due to my vehicle being a theft recovery. However they have performed multiple recalls on this vehicle since I have owned it with the theft recovery title. They also performed the transmission reprogram after I had it fixed at no charge. NHSTA itself states salvage/rebuilt title is no reason for not performing a recall except in exceptional circumstances when car is no longer drivable. I am asking for help in getting audi to honor the recall. Had I been on the highway I would have been smashed when the car shut down.
