2019 Audi A8 problems

Filed Nov 2, 2026 · Electrical · NC

The vehicle suffered a sudden, catastrophic failure of its 48V electrical charging system while in motion, resulting in an immediate and dangerous loss of motive power. Without any warning, the vehicle displayed an 'Electrical System Malfunction' warning on the dashboard and completely shut down, leaving me stranded in active traffic. This inherent engineering defect cuts power to critical safety-critical subsystems, causing a severe and sudden reduction in steering assist and braking performance. This component failure creates an extreme, un-alerted safety hazard on public highways. Audi has issued a class-action settlement for the underlying Belt Starter Generator (BSG) that charges this 48V subsystem, proving they are aware of the manufacturing defect. However, authorized dealerships are actively manipulating diagnostic criteria to deny repairs, forcing consumers to drive un-repaired, safety-compromised vehicles that pose an imminent risk of a severe rear-end collision or highway accident.

COMPLAINT: Authorized dealer non-compliance with the federal safety agency Compliance Recall 25V900 (Rearview Camera Software, FMVSS No. 111). Vehicle is a 2019 Audi A8 subject to Recall 25V900, issued by the manufacturer in January 2026. The recall work was scheduled with an authorized Audi dealer in Southern California by telephone. The dealership representative confirmed an appointment for April 17, 2026 at 2:30 PM and represented that the service would take approximately two hours. The appointment was then confirmed in writing three separate times by SMS from the dealership: twice from its scheduling line on April 15 and April 16, 2026, and once on April 16 at 12:38 PM by a Business Development Manager from the dealership main line, who expressly acknowledged the scheduled service and used it to solicit a vehicle appraisal. On April 17, 2026 the vehicle was presented at the dealership at the scheduled time. The service advisor on duty stated that the vehicle would have to be left until the following Monday and could not be serviced that day. He refused to provide any reason for the change. He refused to identify who had scheduled the appointment. He refused to contact the service director on the owner's behalf. A direct call to the service director at the number on his business card was not answered. The vehicle was returned without service. The recall remains uncompleted. The dealer's conduct effectively imposes an unreasonable burden contrary to the obligations of 49 U.S.C. § 30120 and 49 CFR Part 577. GENERAL GUIDELINES: - Component: rearview camera software (subject of Recall 25V900). - Safety risk: per the recall notice, the software issue may prevent the rearview camera image from displaying, decreasing visibility when reversing. - Confirmation: the recall was identified by the manufacturer; the dealer accepted and confirmed the appointment four times (1 verbal, 3 in writing) before refusing. - No physical inspection has occurred; the recall has not been performed. -

Complete Engine Failure - Audible Engine Knock Noise. Bank 2 Knock Sensor Faults stored & recorded at Audi of Hoffman Estates. Worked with Audi Of Amercia where they denied any wrongdoing or know issues. Bore socped engine at an independent shop & confirmed the cyclinder 6 bore was scored due to picton failure. Paid for a USED engine replacement & install out of my pocket on 8/5/2025 $4,655.57 Install Charge $6,760.49 Used Engine Cost On 9/8/2025 I recieved a letter in the mail from Auid Of America Outling a Piston Skirt Limited Warranty Extension. I reached out to Audi of Amercia the following day, outlined my experiece and was unaware how at no time during my phone calls & emails with Audi of America was a piston skirt issue never discussed. I had the bear the cost of engine replacement out of pocket as during the time frame of failure and per Audi - The repalcement engine was on "intergalactic backorder". When I reached out to Audi of America to discuss reimbursement my claim was denied due to "incompitible or aftermarket parts", which they then changed there response and said it was due to "used" parts being installed. The contact at Audi Of America was Rebecca Gray - To this date she is no longer returning phone calls or emails, also had my email address blocked from the Audi Server at one point. When I reached out to a high up executive via text message, I didn't recieve a response but my email was unblocked in short order. Audi has tried to hide the extent of the piston skirt issue from its consumers & the federal safety agency. This needs to be stopped.

Electrical Malfunction light came on and it says to pull over and cut your car off and also contact your dealer. This is very scary because you may be in am area that is very isolated or dangerous to stop. This is very disturbing. This is a known problem by Audi. The vehicle is currently at the Audi dealership. There were no warnings prior to this.

While driving on highway my car experienced massive electrical malfunction. All systems shut down (including dashboard) and engine cut off. I think it was a miracle that I was able to pull over to the roadside parking lot without any accident. The issue was caused by faulty design of the starter-alternator combo that may render the car undriveable (single point of failure). I had to use a tow track to get my car to nearest dealership where it is right. I think it is extremely dangerous to have cars on the road with possibility of total breakdown without any warnings. My car has only 43000 miles on it so this was totally unexpected and created safety hazard for any all drivers nearby. I just checked some internet boards for Audi and apparently there are many other cars that experienced that issue.

The sunroof on my 2019 Audi A8 spontaneously exploded around 445 pm on Friday, April 7, 2023. The car was traveling around 55 MPH and the sunroof just exploded out. The sunscreen was closed at the time. It was not hit by a rock or a tree limb or any other item. It just exploded. Sounded like a gunshot when the car was brought to a stop, there was a large hole in the sunroof and glass scattered all around the hole.

Hello, On April 6th, 2023, at 12 pm, my car experienced a electrical malfunction within the Start/Stop system, which didn’t posed an immediate threat to my life. Later that day, the car stalled on me while driving, causing a highly dangerous situation on a busy street during peak traffic hours. Multiple error codes appeared, and the transmission failed, leaving me in a perilous position. It is alarming that AUDI is aware of this life-threatening issue, yet no recall has been issued thus far. I urge the federal safety agency to take swift action and hold AUDI accountable for this critical failure, which endangers not only my life but the lives of others on the road. Please refer to the link below for evidence supporting my claim. The issue is widespread, affecting various models of Audi, including the 2019 A6, A7, and A8. https://www.audiworld.com/forums/a7-224/2019-a6-a7-a8-electrical-failures-3037487/
