POWER TRAIN
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.

UNKNOWN OR OTHER
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.

POWER TRAIN
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.

The headlight assembly failed and manufacturer accepts no responsibility and quoted astronomical repair cost. This should not have been an issue with such new components. I've seen many vehicles like mine with the same problem.

FUEL/PROPULSION SYSTEM
Shortly after starting the car, and while exiting a parking lot, the car stalled and lost engine power. I was able to start the car back up for long enough to be able to pull back into the parking lot however after the car got parked the engine refused to start and stay running for the next hour. After a check using OBD11, the codes were showing the cause of the original problem was low fuel pressure which ended up causing misfires. The only way I was able to get the car running and staying running was by purging the system repeatedly by turning on the ignition without starting the car. This has all happened once before while I was driving at relatively low speeds (around 25 MPH) in a town, and I had to go through the same process. No warning lights show for the first multiple attempts at starting the car until it consistently fails to start. No inspections have taken place.

TIRES:SIDEWALL, TIRES:TREAD/BELT
225/45r17 Dry rot on all four tires less than three years old - and actually used for fewer than 18 months as alternated with winter tires - crack runs entire circumference of tire - deep - at joining of sidewall to tread. Nokian has said that this is “cosmetic sidewall cracking” - there is nothing cosmetic about it and each tire dealer I have visited reports that the tires are unsafe and need to be replaced. This is also supposedly a known issue that Nokia has acknowledged but not provided any extra coverage for.

FUEL/PROPULSION SYSTEM, SEAT BELTS
Dear NHTSA, I am filing a complaint about the handling of a recall repair on my 2015 Audi A3 (VIN: [XXX] ) for the suction jet pump. The service experience has been frustrating and raises concerns about the repair’s quality. 1.First Visit - Inadequate Information: During my first visit to the service center, over an hour away, I was turned away because my fuel level was too high. I was never informed that my gas tank needed to be below a certain level for the repair, resulting in wasted time and travel. 2.Second Visit - Check Engine Light Still On: On my second visit, the suction jet pump was supposedly repaired, but my check engine light remained on. I had informed the service advisor that the light was related to an EVAP system malfunction, which I was told could be caused by a faulty suction jet pump. After speaking with multiple mechanics, I learned that a malfunctioning suction jet pump could cause fuel to enter the EVAP system, damaging parts like the purge valve or charcoal canister. 3.Unreasonable Charges: The service advisor insisted that the remaining EVAP issues were unrelated to the recall and wanted to charge $220 for another diagnostic and repairs, without even inspecting the car after the recall service. This seems unfair, as there’s no way to confirm without a proper check. 4.Missing Seat Belt Buckle: After the recall service, I discovered that the rear driver’s side seat belt buckle was missing. This is a major safety concern and needs to be addressed. I request NHTSA’s help in investigating the repair quality and ensuring these issues are resolved fairly. Thank you for your attention.
