I'm writing to report a serious safety issue with my 2023 Audi Q4. Today, Tuesday, October 6, 2026, at approximately 7:18 p.m. Eastern, my vehicle suddenly failed to accelerate from an intersection while I was driving, which nearly caused an accident. I was making a left turn from a T-intersection crossing a lane with opposing traffic, but my car accelerated very slowly causing the perpendicular to break (and honk). Fortunately, they were paying attention and slowed appropriately. Given the…

I tried to charge my Q4 at home, the charging connector to the car had warning red light. So, I checked up dashboard. It's said that AC charging is limited. Eventually, I can't charge. I went to the audi dealer. They said it's simple software issue. Waited 2 hours, one day works fine. Same issue. They don't know what to do. I am still wating from audi USA.

Within the first 6 months of owning the car my 2024 Audi Q4 E-tron premium door handle lock - unlock would not work and the car would intermittently not start. The dealership service replaced the 12-volt battery which has corrected the door handle lock-unlock issue; however, it has not corrected the no start problem. If I exit and enter the car multiple times it will eventually start (automatic seat start). The dealership service department cannot reproduce the problem therefore no solution…

On Saturday, XXX, my [XXX] daughter, who was driving my [XXX] and [XXX] daughters home, called me to tell me that the vehicle failed and that she had safely pulled into someone’s driveway.

The air conditioner warning light came on in April 2026. I took it to dealer to be checked. Dealer said no problem. That warning light went on intermittently through May, June and July. By end of July I took it back to dealer. The evaporator was indeed malfunctioning and emitting carbon dioxide into the cabin when the air conditioner was on. While repairing the evaporator system, the plastic cover over the ground stud broke and required replacement. The vehicle was out of service for 10…

The vehicle and the affected charging components are available for inspection on request. Safety risk: because the vehicle cannot be dependably charged, it can be left without sufficient power to complete a trip,…
