2019 Audi e-tron Electrical System Problems

“Electrical system malfunction- Please park vehicle safely”popping up on the dashboard. This is the second incident of such. Then “ a low battery charge “ warning while charging the car. Warning adds “ battery will charge while driving”. We called the dealer the first time and told to monitor but ok to drive. Then today while traveling almost 3 hours away from home, message pops up again. Dealer contacted and said ok to drive but bring the car asap in shop. Challenges - safety of travelers as issue limits ability to truly know state of charging battery , risk of crash as electrical system main part of EV car. Unsafe conditions putting lives at risk.

INCIDENT SUMMARY: On [XXX], I brought my 2019 Audi e-tron (VIN: [XXX] , 70k miles) to Audi Salt Lake City for Safety Recall 93U9 (High Voltage Battery Module). Vehicle was functioning normally with no warning lights or electrical issues. IMPROPER RECALL COMPLETION: The dealership's technician (Chris Miller, [XXX] ) documented in the service notes: "I FOUND THE GROUNDING STRAP FOR THE REAR MOTOR WAS NOT INSTALLED AND WAS TUCKED UP BETWEEN THE MOTOR AND THE COVERS." This proves the technician failed to properly reinstall the critical grounding strap during recall service, leaving it disconnected in the high voltage system. IMMEDIATE FAILURES AFTER RECALL: Following the recall service, multiple critical failures occurred: Voltage converter failure (part #4KE-907-171-C) Battery charging malfunction (limited to 100 miles range vs normal 200+ miles) Multiple stored fault codes and dashboard warning lights Rear drive motor faults Parking brake system failures All failures are consistent with loss of proper grounding in a high voltage EV system. SAFETY CONCERNS: The technician drove my vehicle 55 miles during service (odometer: 70,651 IN to 70,706 OUT). Why didn't they notice the warning lights during this excessive test drive? Operating a high voltage EV with improper grounding creates risk of electrical fire, shock hazard, and component damage. How many other vehicles at this dealership had recall 93U9 improperly completed? DEALER RESPONSE: Dealership attempted to charge me $2,089 for repairs caused by their incomplete recall work. When I disputed, the General Manager threatened to call police if I didn't return the loaner vehicle. No repairs were ever authorized by me. INVESTIGATION REQUESTED: Please investigate Audi Salt Lake City's recall 93U9 completion procedures and quality control. This is negligent completion of federal safety recall work that endangered my safety and may affect other e-tron INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Airbag detection system continues to malfunction. When driving at random times it states the detection system is currently unavailable as well as all the function buttons on the steering wheel.

Batery is giving electrical malfunction alert. Dealer diagnosed SX6 failed, replaced at 52,991 miles on Dec 22, 2022 (they agreed to replaced free of charge), at 104,741 miles on Jan 6 2025, dealer diagnosed sx6 failed again, needed to be replaced.thry refused to replace at no charge. During the research online I found that many audi EV cars owners reported the same problem which SX6 failure could potentially causes the car could completelystop while operating.

My 2019 Audi E-tron has experienced two major issues during my ownership. At around 87k miles, I was driving into a parking lot and suddenly a “electrical malfunction” warning light appeared on my dashboard followed my many warning lights including 4wd, brake system, and battery. The vehicle was not moving properly and I had to slowly move it into a parking lot and had it towed to the dealership. The issue was that the front motor is toasted caused by coolant leaking into the motor. The second issue occurred around 109k miles. My vehicle couldn’t start in a parking lot and the same “Electrical Malfunction” warning light went on. The vehicle was towed to Audi dealership and the diagnosis was a failing SX6 battery control module, which costed me over $8000 to repair. Those two issues both make the vehicle unmovable and could be catastrophic if they occur at high speed. There are numerous complaints from Reddit and E-tron forum regarding the same two issues. Both issues involved moisture getting into critical electrical components and could put the safety of passengers and other vehicles on the road in danger. The Audi USA has extended the warranty for the motor issue but hasn’t done anything regarding the SX6 modules. The vehicle’s electrical motors and HV battery should be closely inspected since those issues are prevalent and could be related to serious design flaws from factory. Audi USA hasn’t addressed those issues properly and it didn’t have a proper fix for its self discharging battery as well, which puts this vehicle unsafe to operate on the road.

2019 Audi Etron that still doesn't have a resolution for the safety recall of High-Voltage Battery Module(s) AUDI ACTION CODE 93U9, NHTSA RECALL NUMBER 23V867, issued Dec 20, 2023 for a potentially critical self-discharge condition exists in certain high-voltage battery modules that, in some instances, may lead to thermal overload, possibly resulting in smoke or a fire. A high-voltage battery overheating increases the risk of a fire. Putting a sticker on the dash saying not to charge to over 75% and software that reduces the mileage I can drive is not a fix.

On the very day I purchased the vehicle (07/22/2025), the high-voltage battery module pack failed, and the vehicle had to be immediately taken back for service. I did not receive it back until 08/08/2025. I was told it was fully repaired and safe. On 09/02/2025, the vehicle suffered multiple simultaneous safety-system failures, including: • “Audi Adaptive Light: Malfunction” • “High Beam Assistant: Malfunction” • “Audi Pre Sense: Currently Limited” (collision-avoidance system) • The vehicle also failed to charge that day. As of today, a new “Exit Warning Malfunction” warning has appeared. This is the third critical safety or high-voltage system failure in less than 90 days. At no point was I informed of any prior safety or recall issues before purchase. Each time, the dealership insisted repairs were complete — yet additional safety failures continue. This vehicle appears to have an ongoing electrical/safety system instability, potentially involving the high-voltage battery and critical driver-assistance systems. I am filing this complaint to ensure it is formally investigated before a serious incident occurs.

My car has been under a recall since 2023. I have been at the dealership for normal maintenance and for the recall several times now but the dealership/Audi says that it's monitoring the battery remotely and doesn't replace the battery. No fix has been done until now and the recall/fix keeps being delayed.

No specific incident, but the expected resolution date for this recall has been pushed out 3 or 4 times, and now there is no expected resolution date. I've already implemented the interim step for the recall and had to have a battery cell replaced, which took over 2 weeks for the dealership to complete. It's frustrating to constantly have a potential 2+ week fix hanging over our head, not to mention the fact that they recommend only using the vehicle at 80%, severely limiting our range, and, ultimately, the risk of the battery catching fire or exploding at any point! The recall has been open for almost a year and a half now, and it's only supposed to be a software update to fix it! I'd like to see them actually implement the final resolution!

Subject: Formal Complaint Regarding Water Ingress and Electrical Damage – Seeking Damages Dear Audi Customer Service, I am writing to formally lodge a complaint regarding significant issues with my Audi vehicle, which have led to severe damage and financial loss. Below are the details of the incidents: Initial Incident of Water Ingress: A few months ago, my Audi experienced water ingress through the sunroof, causing water to enter the front of the vehicle. This issue was addressed and repaired by your dealership under warranty. Recent Incident of Water Ingress: From June 13 to June 15, during heavy rains in Florida, my vehicle was stationary and parked. On [XXX], while driving the vehicle, I noticed an electrical burning smell and had to stop immediately. All the lights were displaying errors. Upon taking the vehicle to the Audi dealership, it was discovered that there was water ingress into the battery area and the rear of the vehicle. Despite the previous repairs for water ingress, the recent inspection revealed extensive water damage. The dealership has stated that the damage cannot be repaired under warranty and provided an estimated repair bill of $23,000. Consequently, my insurance company had to declare the vehicle a total loss. Given the history of water ingress issues and the failure of the initial repair to prevent further damage, it is evident that there is a significant defect in the vehicle. It is unacceptable that such a defect has not been adequately addressed, posing a safety hazard to consumers. PLEASE INVESTIGATE AS I AM not the only victim of this problem and audi is aware.

I received the letter about 23V867 recall on this vehicle over two weeks ago. Letter indicates vehicle requires repair (per Audi's online data as recorded with data collection performed from the vehicle itself) NOW. I called to make an appointment with Audi Silver Spring [XXX] ) and initially I was told they will have to order new battery modules. A week later (this morning 2/29/2024) I was texted that they cannot perform the repair as they do not have cell balancer tool :( and this will take another two weeks. So while Audi indicates my vehicle is in imminent fire hazard, yet their dealers are not capable of repairing this issue, even though letter indicates repairs should be performed now. I am extremely concerned with the safety of the vehicle, passengers and my property while vehicle is parked on the driveway due to fire hazard. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
