2016 AUDI A3 Complaints

The contact owns a 2016 Audi A3. The contact stated that the front passenger’s side air bag occupant sensor failed to identify a passenger seat in the seat. A dealer was contacted. No warning light was illuminated. The vehicle was taken to a dealer where it was diagnosed and determined that PODS had failed and needed to be replaced. Additionally, the engine was consuming an excessive amount of engine oil. The vehicle was not repaired. The contact associated the failure with NHTSA Campaign Number: 19V474000 (AIR BAGS); however, the VIN was not included in the recall. The vehicle was repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 44,000.

This vehicle was involved in a rear end collision in late 2025. The vehicle was just sold at auction with a clean title even though it has frame damage that is more than 100% of the cost of this vehicle. It is sold with a clean title and I am worried that a used car dealership will try to sell it with no accident history and clean title to an unsuspecting person.

FUEL LEAKED ALL MY GARAGE ALMOST CAUSING A FIRE IN MY HOME WHILE I WAS SLEEPING. I HAVE HAD THE FUEL TANK REPLACED 3 TIMES. AND I HAD TO PAY OUT OF POCKET TO HAVE IT REPLACED BECAUSE AUDI WOULD NOT REPLACE THE RECALL OF IT SO I AM REACHING OUT TO YOU SO YOU CAN REACH OUT TO AUDI ABOUT NOT STANDING BY THE RECALL PROCEDURE!

My 2016 Audi A3 Sportsback E-tron vehicle was parked at my house. When I went to start it the engine did nothing, no power. The message “Driver System Fault” and a red triangle with a red ! in the middle was displayed on the instrument panel. I was unable to start or operate the vehicle. I called AAA and they towed the vehicle to a Recharge Hybrid pump location near my house. I tired to charge the battery and it would just turn off. Then I called AAA again and they towed my car back to my house and checked the small 12 volt battery to see if that was the problem, they determined that the 12 volt battery still had 75% life in it. They were unable to get my vehicle started. The same message is still on the dashboard “Driver System Fault." The failure mileage is approximately 81,567. I want to know before I call the Dealer and get it towed again if this issue is the Hybrid High-Voltage Battery or the housing bonded seam could have lead to corrosion the service recall from a while ago. Service Action Code 93D2

The contact owns a 2016 Audi A3. The contact stated that while the vehicle was parked with the engine running, the vehicle experienced a sudden loss of motive power. During the failure, the message “Driver System Fault” was displayed on the instrument panel. The contact was unable to restart or operate the vehicle. The vehicle was towed to the dealer, where it was diagnosed and determined that the Hybrid battery had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 83,000.

The rearview camera is failed. Yes I can have an inspection done. Yes, dealer confirmed that camera is failed but wanted hundreds of dollars to troubleshoot. Has not been inspected by police or insurance. No it just stopped working one day.

The rear wiper hose is consistently getting completely clogged so that no fluid comes out when the spray mechanism is engaged. The dealership has replaced it for a fee two or three times. At the last service they told us they cleaned it and did not charge a fee. However, within two months it was clogged again. I have noticed that the issue is more likely to occur after (intentionally or accidentally) using the rear window defroster. I am therefore wondering whether the hose is made of a plastic that is too soft, causing it to change shape as a response to the defroster heat.

Mechatronics unit failed, stalled on freeway nearly caused an accident behind me.

The contact owns a 2016 Audi A3. The contact stated that the air bag warning light was illuminated. The vehicle was taken to the dealer who diagnosed that the front passenger’s seat air bag sensor had failed and needed to be replaced. The vehicle was repaired under NHTSA Campaign Number: 21V198000 (Air Bags). The air bag warning was illuminated approximately one and a half years later. The vehicle was returned to the dealer who informed the contact that the repair was no longer covered under warranty. The vehicle had not been repaired. The manufacturer was made aware of the failure and a claim was opened. The failure mileage was approximately 67,000.

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.
