2021 Audi SQ5 Problems

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 not match the OEM calibers. It was smaller than OEM, we called the Audi dealership where I bought it from and they said it was sold as it is. We explained to them how that was a major hazard, but they told us it’s nothing they could do. Whoever did the safety inspection did not do there following job, I am just glad nothing has happened but it is a major concern. I have videos of the tapping noise after picking up my car, but it won’t let me upload to the files.

The engine water pump on this vehicle is leaking both internally and externally. This vehicle uses the 3.0T (EA839) engine, which uses a vacuum-actuated water pump with a shroud sleeve mechanism. A licensed repair facility diagnosed the failure and estimated repair cost at approximately $5,500. The internal leak path allows coolant to migrate into the vacuum system rather than escape as a visible external leak. This means the failure can progress without producing the puddle or drip that owners are trained to look for during routine visual checks, delaying detection until damage has advanced further and the repair has grown more extensive. At the time of failure I observed low coolant warning, which is documented as a symptom of this failure mode. This failure is reported by independent repair shops and owner communities as occurring predominantly in the 40,000-70,000 mile range, which falls just beyond Audi's 4-year/50,000-mile factory warranty. The design is used across multiple Audi models and model years sharing the EA839 2.9T/3.0T engine, including the SQ5, S4, S5, A6, A7, and Q7. This defect is the subject of pending litigation, [XXX] v. Volkswagen Group of America, Inc., Case No. XXX ([XXX], filed XXX, which alleges Audi was aware of the defect since at least 2018. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

My car has a known issue with a piston skirt defect that can cause engine failure. Audi of America acknowledged this issue with the EA839 and only warranted an 80k mile warranty. I am outside of that warranty and in risk of catastrophic engine failure that could lead to safety issues on the road. I am worried about my safety in driving this vehicle. Audi of America refuse to cover my car as it is outside of the extended warranty. There are numerous people that have the same issue as several models with the same EA839 engine and are prone to this failure.

The contact owns a 2021 Audi SQ5. The contact stated that while the gear shifter was shifted into reverse, the rear-view camera displayed a blank screen. As a result, the contact stated that he bumped into another vehicle. The vehicle was taken to the dealer where it was diagnosed that the Back Over Prevention system failed, and the infotainment unit software needed to be replaced. The vehicle was repaired. The contact then stated that he then received notification of the NHTSA Campaign Number: 22V742000 (Back Over Prevention). The manufacturer was notified of the failure and the contact was informed that the recall was previously repaired. The failure mileage was approximately 10,715.

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.

I’ve had a Safety System Malfunction light on for sometime now. Dealership replaced a seat belt part, air bag control module, and still the light won’t go away. The car is currently with the dealership.

The Lighting system is SUB-PAR because You NHTSA has been dragging your feet on approving the ADB Matrix Headlights and allowing AUDI to update the software and enable the system. This is a Safety issue as we cannot realize the full capability of visibility when driving on the highway! NHTSA, please get your ACT together and approve the ADB Headlights!
