NHTSA Complaint #11693878 — 2019 AUDI A8

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 & NHTSA. This needs to be stopped.
