ELECTRICAL SYSTEM

While driving, the vehicle displayed three simultaneous warnings — “Drive system malfunction, safely stop vehicle,” “Electrical system malfunction, restart not possible, contact service,” and “All-wheel drive malfunction, limited stability” — and lost propulsion completely. This occurred on at least two separate occasions while driving. After each event, the vehicle would not restart for approximately 15 minutes, after which it began working again temporarily. The vehicle was taken to an authorized Audi dealer, which found no coolant in the front drive motor and diagnosed a fault in the SX6 high-voltage battery switching module, which controls connection of the high-voltage battery. The SX6 module was replaced. This followed a separate repair approximately three months earlier for a failure of the J1050 high-voltage battery charger control module, which had to be replaced twice due to communication failures with the vehicle’s electrical system. I am concerned this represents a recurring high-voltage electrical system defect that creates a risk of sudden loss of vehicle control/propulsion while driving.

ELECTRICAL SYSTEM,SERVICE BRAKES

The vehicle is experiencing an intermittent but active 'Electrical system: malfunction!' safety alert on the dashboard and myAudi app, caused by an internal high-voltage battery cell circuit fault (Diagnostic Trouble Code P0DB400 / U04A300) and a failure in the battery thermal runaway detection system. When the fault occurs, the vehicle suffers a complete loss of regenerative braking, severely affecting stopping predictability and vehicle handling. An authorized Audi dealership (Audi West Chester) confirmed the internal module failure under TAC Case NF-1675032 and directed a full battery module replacement. Diagnostic scans have confirmed two highly critical manufacturer trouble codes: P0DB400 (Hybrid/EV Battery Cell Balancing Circuit "C") and U04A300 (Invalid Data Received From Hybrid/EV Battery Interface Control Module "C"). However, a second dealership (Audi Cherry Hill) is refusing to honor the High-Voltage Battery Warranty or perform the necessary repairs because the safety code is currently showing as 'static' during their stationary test. Leaving an active high-voltage balancing and thermal tracking defect unaddressed poses an immediate risk of a sudden vehicle shutdown while driving or a potential thermal event.

UNKNOWN OR OTHER

From time to time the driver's door does not latch completely so the door is only partially closing. Dealer was able to duplicate the problem but will not replace (estimated cost for new door latch is just under $800.) at their expense. It appears that others have had the same problem. When driving the car air rushes into the vehicle as the door is not fully shut. I worry that this problem could be very serious should I be in an accident with a partially closed door rather than a fully closed door. The problem first appeared early in the winter and seems to be getting worse.

SERVICE BRAKES

Brakes were replaced by Audi with genuine Audi parts and within 2 months, the brake rotors became warped, requiring a resurfacing. After driving another 2 months, they once again became warped, making the entire car lurch and shake during braking.

POWER TRAIN,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE

My drive motors keep failing (so far 3 times) and my emergency braking abruptly stops my vehicle when no true danger is present and I’m in complete control of my vehicle. Currently my vehicle has a constant shuddering while braking which doesn’t feel safe because it’s not braking properly. Audi regional and the dealership refuses to take ownership of the issue. Dealer has confirmed issue and replaced drive motors three times. Each time my braking system has gotten worse. The part was replaced each time under warranty but Audi has not confirmed that a fix has been found and corrected. This means it can occur again and abruptly which can absolutely be a safety hazard as it was each time it failed on me.

ELECTRICAL SYSTEM

The contact owns a 2022 Audi E-Tron. The contact stated that while driving at various speeds, the vehicle independently switched to SAFE Mode and failed to properly accelerate while depressing the accelerator pedal. Additionally, the mileage range was reduced, and the battery recharging time increased. The failure started after the vehicle was repaired under the NHTSA Campaign Number: 23V867000 (ELECTRICAL SYSTEM). The vehicle was taken to the local dealer, but no failure was found with the vehicle. The vehicle was later taken to an independent mechanic who reported that the amperage of the battery had been reduced from 400 amps to 130 amps. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 16,000.

ELECTRICAL SYSTEM

CATASTROPHIC ELECTRICAL FAILURE - SMOKE IN CABIN While driving with passengers, dashboard displayed "ELECTRICAL FAILURE - PULL OVER WHEN SAFE" followed by loud explosive POP and cabin filled with SMOKE. ROOT CAUSE: Prior undisclosed collision damage. Dealer (Morrie's Golden Valley Cadillac) removed front bumper in June 2025 (Repair Order #78683), then sold vehicle as "no accidents" in August 2025. Subsequent inspection revealed cut wiring and improper repairs (Invoice #94609). CURRENT STATUS: Vehicle inoperable 3+ months. Audi corporate technicians have repaired major problem however vehicle still has charging issues that happened right before the catastrophic failure unable to repair. SAFETY CONCERN: Smoke-filled cabin endangered occupants. Potential fire hazard.

ELECTRICAL SYSTEM,LANE DEPARTURE,BACK OVER PREVENTION

The vehicles software system regularly crashes and/or does not load leaving all camera functionality and safety alerts inoperable. I have had the vehicle in to address these concerns 5 times with no resolve from the manufacturer. Even with video evidence they claim the vehicle is functioning as intended. This is in direct violation of FMVSS 111 as the rearview camera is regularly not available. Sometimes the system reboots within seconds and sometimes it takes 10 minutes or more.

ELECTRICAL SYSTEM,ENGINE

The car occasionally does not respond to pushing the pedal to accelerate. The first time it happened, I though it was user error after sitting at a light. Well within the same 30 minutes it happened again entering a carwash. Today I was sitting at a light waiting for it to turn green. Once green, I pushed the accelerator to go and the car would not accelerate. This is the second time in two weeks and approximately fifth time since I purchased the car in October 2023. No dashboard warning prior to this.

SERVICE BRAKES

Brakes do not work when there is a precipitation. You need to press the brake 3 times before you can feel the brakes engage. This occurs anytime it rains or snows for the entire time we’ve owned the car and Audi refuses to acknowledge the complaint
