Example complaints

Electrical system: “My vehicle was excluded from Recall 25V20100/90VC; however, in early March 2025, it experienced the exact defect described in that recall: a complete failure of the instrument panel module. I paid $3,737.07 for the repair just weeks before the official recall began in late March 2025. I submitted a reimbursement claim to Audi of America under 49 CFR §573 and §577, including the paid invoice and all relevant documentation. Audi has since denied my claim. I am requesting your help to determine why my VIN was excluded from the known safety defect population. …”

NHTSA complaint #11720755, filed 2026-02

Forward collision avoidance: “Today, I was in a protected left turn lane prior to making the turn. When oncoming traffic (4 lanes) cleared, I gently pressed the gas pedal to start the turn, but a red “pre-sense” error triggered and slammed on the brakes. I moved my foot to the brake and then back to the gas, and the error cleared, allowing me to continue the turn. This was dangerous as I could have stopped in front of oncoming traffic or been rear-ended by the car behind me. …”

NHTSA complaint #11476690, filed 2022-07

Fuel system: “The car's fuel guage has been inaccurate since the initial purchase. It would always hang at around 50% and then drop to 5% within 10 miles. Thankfully, we are aware and just check the miles driven so we do not get stranded. Requested fix by dealership, they said there was nothing wrong. The recall for my car appeared and I asked for a fix, they said it's not available yet. It's been 6 months and there's still no fix for this. It would also have random computer issues such as screen shutdowns, and take to dealership warnings after the 1st 10k checkup. …”
