We have a brand new e-Tron and it's been a nightmare! On our first full day with the vehicle, I charged the car overnight, and the car showed charging complete with a range of 230 miles. We drove 63 miles that day, but the range dropped to 31 miles. It was a very scary drive because the range was dropping so fast--two or three miles coming off the range every eighth of a mile for much of the drive, and we had no prospect of charging. Luckily, we made it to our destination. But, things kept getting weirder. Audi advertises that the battery charges fully in 100 hours (or about 4 days) using a normal household outlet, which is all we had available. After eight days, the car is stuck at 139 miles of range, and says "Charging ended"--so the vehicle won't accept more charge. We are very nervous about our return trip tomorrow because, if the car loses mileage like it did on the way here, we will end up in the breakdown lane with no power at all. We also tried charging the car with 240v, and it still says "Charging ended" and won't take more charging. Obviously, our car is going straight to service as soon as we are back home, but just curious if anyone else has had these kinds of battery problems and what I should be sure to ask the dealer before taking possession of the car again. (Note: driving conditions have been around 50F, some rain, no unusual weight. The range decreased the fastest on a long, flat freeway driving 67-70MPH).
