2022 AUDI E-TRON Complaints

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.

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.

The integrated high-voltage powertrain / single-speed transmission unit is failing, causing severe mechanical chattering, rapid actuator cycling, and vibration under the vehicle. This failure follows a recent catastrophic, unexplained total loss of traction/HVAC coolant while at a previous Audi dealership. Audi is aware of systemic coolant migration issues into the electric drive motors on 2022 e-tron models under Technical Service Bulletin (TSB) #2073858, where coolant breaches internal seals and compromises the gearbox oil, causing mechanical failure. The current dealership has taken a fluid sample but refuses to share the results, denying a high-voltage drivetrain warranty submission and demanding I pay out-of-pocket for a standalone "transmission" failure. Crucially, the dealership has explicitly documented on my file that "driving the car further will cause further damage," yet they are forcing me to pick up and drive this un-diagnosed, potentially hazardous vehicle off the lot on Monday. If the high-voltage motor shorts due to internal fluid contamination while driving, it creates a severe safety risk of a sudden loss of propulsion on active roadways.

Component/System: Service Brakes, Hydraulic / Brake Pedal Assembly / Steering Linkage Description of Defect: A progressive mechanical noise and physical sensation occurs during driving transitions involving the brake, accelerator, and steering column. After the brake pedal is fully released and the accelerator is pressed, or when the steering wheel is turned, a distinct loud "thunk" and a sliding/dragging sound emanate from the brake pedal assembly area. When the accelerator is released, a secondary "click" sound is heard and felt through the controls. This condition did not exist when the vehicle was new and has progressively worsened in frequency and volume. The symptoms suggest a binding mechanical linkage, failing master cylinder pushrod bushing, or interference with the steering column shaft, potentially compromising braking response or causing pedal entrapment. Safety Risk: The physical sliding sensation and mechanical degradation pose a severe safety risk. Mechanical binding or un-isolated movement within the pedal box can cause unexpected resistance or delay when transitioning to emergency braking, increasing stopping distances or causing total failure of the brake pedal to actuate or return properly, increasing crash risk. Dealer / Manufacturer Actions: The vehicle was presented to an authorized Audi dealership. Comprehensive video and audio evidence explicitly capturing the exact "thunk," dragging noise, and click during vehicle operation was sent directly to dealership staff. Despite having irrefutable video confirmation of the defect, the dealer has refused to properly diagnose or address the issue. The dealership is now completely ignoring all communication, failing to return calls, and disregarding this critical safety defect. Warning Symptoms: No electronic dashboard warning lights or fault messages. Symptoms are strictly mechanical and acoustic, amplifying over time.

Running 4430 MMI/MIB3 software (that was release almost 2 years ago) and now have stereo EQ settings that reset on their own, personalized favorites that delete on their own, and other personalization settings that reset on their own. Happens every 6-24 hours if settings are adjusted. Audi knows about it, refuses to allow dealers to update to newer software that will fix these since there are updated available that solves.

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.

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.

A vehicle was taken to a collision repair facility following minor front-end damage. At intake, the repair facility documented visible exterior damage but did not perform or document an underbody inspection, which is necessary to assess high-voltage battery integrity in electric vehicles. After the vehicle entered teardown, the repair facility later claimed that the high-voltage battery was damaged and recommended that the vehicle be declared a total loss. This determination was made without documented evidence of required OEM diagnostic procedures and without initial intake documentation supporting battery damage. The sequence and timing of documentation raises concern that the battery damage determination was made after teardown rather than through proper inspection protocols. A subsequent manufacturer-level evaluation did not support the claim of battery damage. This situation presents a safety concern regarding whether proper high-voltage battery inspection and handling procedures are being followed by collision repair facilities. Misidentifying or improperly handling high-voltage battery conditions in electric vehicles can pose safety risks, including potential thermal events, improper classification of vehicle safety, or unsafe return to service. This complaint is submitted to request review of whether proper safety and OEM procedures were followed in evaluating the high-voltage battery, and whether this reflects a broader safety issue in electric vehicle collision repair practices.

Purchased a used 2022 Audi E-Tron GT with an open NHTSA safety recall for high-voltage battery fire risk (Recall 24V726 / Audi 931A). The recall remedy had not been performed at time of purchase. The selling dealer completed a pre-delivery inspection two weeks prior to sale with full knowledge of the open recall. Within 7 weeks of purchase, the vehicle entered limited performance mode (turtle mode) while driving and had to be towed. A high-voltage coolant pump was diagnosed faulty and replaced. Days later, the vehicle powered down completely while driving. Fault codes indicated an implausible signal from the HV battery controller. The battery management controller (J840) was replaced. After replacement, additional faults were found. The HV battery switch box (SX6) was also diagnosed faulty and replaced. The vehicle was out of service approximately 18 days for this event alone. Within 11 months of purchase, the vehicle developed water intrusion in the trunk area traced to a faulty spoiler motor sealing surface. This caused corrosion to the center tail lamp connector, electrical shorts to all three tail lamps, and required repair of six wiring harness connections. A body electrical wiring repair was also documented in service history prior to purchase, suggesting a pre-existing sealing defect. Total: 9 dealer visits and 50+ days out of service in under 14 months. All repairs performed under manufacturer warranty. The open safety recall was not completed until 8 months after purchase.

After dealership service and recall-related calibration work, my vehicle developed multiple safety-related issues that did not exist prior to service. The dealership documented a diagnostic trouble code for “Hybrid/EV Battery Thermal Runaway Detected” (P29FF00), a critical high-voltage battery safety fault. Instead of diagnosing and repairing the root cause, the dealership cleared the fault code and returned the vehicle to me, stating it was operating as designed. Following this, the vehicle has exhibited abnormal and unsafe behavior, including significant and inconsistent loss of driving range, irregular energy consumption, regenerative braking issues, and braking concerns such as squealing, mechanical drag, and rotor heat buildup affecting stopping performance. Additionally, multiple control modules associated with the recall and calibration work are affected, including systems related to driver assistance and vehicle operation. These systems required recalibration, and the vehicle’s behavior changed following this process, raising concerns about improper calibration of safety-critical systems such as lane keeping and stability functions. The dealership’s documentation confirms fault codes were erased without confirmed repair or root cause resolution. No clear diagnostic explanation was provided for the battery fault or related system issues. Audi of America has been notified and has refused further escalation or assistance, directing all responsibility back to the dealership despite unresolved safety concerns. I am concerned the vehicle is operating with unresolved high-voltage battery and system faults that pose a serious safety risk, including potential battery failure, loss of braking performance, and malfunctioning driver assistance systems
