1) the main safety concern is the 7 speed dsg/s-tronic automatic transmission which feels jerky when reaching to a stop; the breaks fully engaged and the vehicle tries a sudden move forward due to this. various tpi's related to the problem (tpi 2023830/1 jerk when stopping, hard 2-1 shift, s-tronic). audi dealerships are asking for about 500$ just to upgrade the software on the transmission without a guarantee this will fix the problem. also when shifting from n to d it is very sudden and forceful which feels unsafe. 2) brake safety concern: the break pedal sinks slowly to the floor under pressure although the breaks were completely serviced (new rotors, pads, master break cylinder and brake fluid). tested other audi vehicles and a similar behavior was noticed. 3) i had also a failed thermostat which i found to be under workshop campaign 19h3 2024932/1 that indicated same part number for the thermostat to fail but the dealership refused to replace it for free because the campaign did not including my car's vin. initially i was told to take in the car and they will fix it for free but that didn't happen. why does it matter if the campaign does not include a certain vin when the same part number was involved in the failure. as a final note i find outrageous the fact that audi refuses to provide free software updates to fix design issues related to the gearbox and instead charge a considerable amount for fixing safety issue on their vehicles.
