Electrical system

5 reports
“Whenever driving around town or long distance whilst getting to a red light without a car in front or anything and coming to a stop the car beeps and the front parking sensors go off whilst there is nothing up front.”

Engine

5 reports
“I noticed my car started to lose coolant, I checked my water pump and I saw there was a leak on of the hoses. Once I discovered that I also heard a tapping noise coming from the engine. I took it to my local Audi shop, and they discovered that my pistons were going bad. They told me I qualified for the extended piston skirt warranty for my car. While my car was in the shop they replaced all 6 of my pistons. When they told me my car was ready for pick up I picked up my call, drove it for 20 miles and my car started to make a louder tapping noise from the engine bay. I took it back to the dealership the following day they told me they were going to look into it to figure out the problem. Couple weeks go by and I finally get a phone call saying that they can’t do nothing that my car is making that noise due to “outside influence “ I am frustrated because I just had got the car barley drove it around and they are pointing the finger to as if I had to do something with the noise. They said everything now has to be be paid out of pocket. It has been a frustrating experience. Also when they did the whole brake down one of the techs noticed that the front calibers did…”

Power train

3 reports
“While driving at normal operational speeds, the vehicle suffered a sudden, un-commanded, and catastrophic loss of motive power while navigating a live traffic intersection. The transmission completely disengaged all gears without warning, rendering the vehicle entirely stationary and immobilized in the path of oncoming traffic. This failure created an immediate, severe safety hazard, exposing the occupants to a high risk of a side-impact or rear-end collision due to the inability to clear the intersection under the vehicle's own power. The vehicle had to be flatbedded to an authorized dealer (Audi - Glenwood Springs). The professional diagnostic evaluation confirmed an internal failure of the transmission assembly and Transmission Control Module (TCM) / Mechatronic unit, requiring a total replacement of the powertrain assembly. The failure occurred at 59,000 miles.”

Forward collision avoidance

2 reports
“The pre-sense and/or automatic emergency braking function comes on unnecessarily at least once a week. It will occur when I am driving on the highway and the car thinks there is something in front of me and then the seatbelt will tighten out of nowhere. This is a significant safety risk as it is terrifying and is not being triggered for any legitimate reason. It is so abrupt when it happens that it makes me jump while driving. The worst thing that has happened is yesterday I was going down a ramp toward a parking garage. Out of no where for no legitimate reason while on the beginning of the decline of the ramp, the car automatically applied the e-brake very violently. I was whiplashed forward, felt my neck crack, and then hit my head on the visor quite hard. Today, I have a bruise on my forehead and am not sure whether I had a mild concussion from the incident. It was more violent than when I have been rear-ended in the past. There were no walls, cars, people, ceiling, or objects anywhere near the car to cause this to happen. The pre-sense is a defect and a significant safety risk that can and has caused injury to me.”
