2022 Audi Q5 Sportback

With just 800 miles on the vehicle after only having had it for 3 weeks after purchase, we were on the highway at 11pm at night and the engine started violently shaking to the point that the vehicle was undriveable; the emergency warnings on the dashboard came on, and the more we accelerated the more the vehicle shook. The longer we drove it to get to an emergency exit, the more it started shaking. Within about 30-60 seconds the car became completely undriveable. We were told conflicting things from the Audi service center and their technicians. We were first told that this was a complete engine failure that would need a new engine. We were told cylinder 3 lost pressure and was unresponsive. Then we were told it was just one faulty spring that needed to be replaced, and the vehicle was supposedly fine to run. Simultaneously, and in one-on-one conversations, we were privately told by our Service Adviser Flor Fuentes that she had no confidence that the underlying engine issue was actually fixed, and that she felt the service center got lucky in identifying one temporary patch to the problem that got the engine running again, and that she herself would not feel comfortable getting in this car pregnant or putting a newborn child into this car. We then retained a senior independent Audi service technician to make an assessment of Audi’s repair work, and they found several corners were cut in the process of allegedly fixing the vehicle, not least that Audi did not follow its own test driving protocols before trying to hand it back to us. The independent technician also advised that he could not assure our safety based on the path the dealership took in the alleged repair and the corners cut. We also have a recorded conversation with the head of Audi Service at Audi Central Houston where he acknowledges they didn't follow their own safety checks and standards in the process.

1. When parked on a slight incline, vehicle rolls forward (downhill) AFTER shifting from Park to Reverse. Dealership says this is normal, says car will roll forward up to 10 feel even when transmission is in reverse. Appears to be due to a design defect in the electronic transmission. 2. Windows will not open when outside temps are below 20 degrees. Dealership says they have no solution. This car has a bunch of other problems that Audi won’t address, but the above are clear safety issues. Thank you.

Car jerks strongly when slightly accelerate on an incline. This jerking happened 2 more times. After 10 minutes driving on highway, car dashboard shown Electrical System: Malfunction and forced immediate exit off highway. We were on road trip and have to disable hybrid system and hoped no more car malfunction for the next 600 miles home. Took car to 2 service dealers and none could find error codes.
