2021 Audi Q5 E

Six months ago received a warning saying Electrical System Failure: safely stop vehicle. Took it to the dealer. They had the vehicle 30+ days and said they had finally fixed it. Almost immediately began receiving the same error message upon driving vehicle again. Called dealer and asked what to do. They said it must be a sensor problem because they replaced everything. Said it could be ignored. Warning light would come on and then go off periodically but we continued to drive vehicle on dealer's advice. Then, one night, while traveling on a local street, received a warning that there had been a Transmission Failure, and vehicle came to a sudden halt, blocking traffic. Wheels locked, making it extremely hard to get onto a tow truck. Had been driving on the highway shortly before this happened and could have died if the car had suddenly stopped moving at highway speed.

When the car was initially purchased in 2021 a fully filled gas tank and fully charged battery gave a total range of approx 400-420 miles. As of recently the fully filled up gas tank and fully charged battery are giving a digital range reading of 368 miles. At the minimum this is a 32 mile to 52 mile range difference. Took it to the dealership on Jan 2023 after noticing an issue in December 2022 and they are insisting the systems are correct and working. They are refusing to look into the matter. We are not sure if the sensor is wrong or if the car is prematurely stopping fueling internally causing it to not fill and give this reading.
