On Sunday December 19, 2021, while driving home the warning light for the battery/alternator flashed on with an associated beep warning. An estimated 30 miles later all electrical and motor functions died while I was in heavy traffic. I was able to pull off onto a narrow shoulder up a steep hill and park. All functions quit, I could not come out of "Park", the emergency brake switch would not release, the emergency flashers did not function. Nothing responded. I called AAA Towing service to be taken to an Audi service repair shop. The towing service had to use a jumper to provide electrical power to release the emergency brake and take the transmission out of "park." The repair service was the "Sport Hous Reno" where the alternator and the battery were replaced. Invoice # 4791, 12-21-2021, total $1,709.12. I do not expect the battery to be covered since it is expendable. However, the alternator malfunction and this model of Audi completely dying placed me in a dangerous situation where I or my family could have been seriously injured. This is not my first Audi, I did have a similar occurrence with another model and when the battery caused a malfunction the Audi computer went in "Limp Mode" and I was able to drive slowly to the dealership. This was not the case, when the electrical system failed it did not go into "Limp Mode, " it completely "Died" placing me and my car in a dangerous position.

The car leaks oil. Audi of wilmington refuses to repair it. Purchased it in 2015 and have been trying to get repaired. Bought it from Kia of wilmington along with a warranty that was never honored by either. Was told Kia never registered the warranty. Also the car was sold with a lifetime warranty that no-one will honor. The driver door has a shortage and the defrost doesn't work. The alarm works when it wants to. I was told there is recall. Can you help
