What do 2021 Audi SQ5 owners report?
12 of the 13 complaints, the most recent for the most-reported components, as the owners wrote them. NHTSA removes names and VINs; long reports are trimmed. CarHooq has not verified individual claims.
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…
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…
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…
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 the vehicle was taken for routine service at the dealer, and the contact was informed that the coolant pump was starting to fail. The contact was advised that the mechanic found coolant running through the vac lines. The contact was informed that continuing to drive the vehicle with a failing coolant pump could cause engine damage. The contact had the coolant pump replaced. The manufacturer was not informed of the failure. The contact researched online and related the failure to NHTSA Campaign Number: 18V229000 (Engine and Engine…
Component/System: Engine and Cooling — Water Pump / Coolant System Vehicle: 2021 Audi SQ5 Engine Code: CWGD Mileage at Failure: 71,000 Date of Incident: 8/6/2025 Audi Denver I’m reporting a known defect affecting my 2021 Audi SQ5 with engine code CWGD. The engine experienced an internal coolant leak from the water pump housing, which is a known issue previously acknowledged by Audi in TSB #19Q5 2022 01, covering earlier 3.0T engines (DEWA/DEWC). Although my engine (CWGD) is not listed in the bulletin, the failure is identical in nature: the plastic thermostat/water pump housing fails…
MMI not connecting Control module for emergency call module
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…
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!
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…
WHILE DRIVING KID SPILLED WATER ON REAR SEAT, WITHIN 5 MIN ALL SENSORS STARTED BEEPING, DISPLAY STARTED TURNING OFF AND ON, STEERING WHEEL VERY HARD TO MANEUVER, WINDOWS OPENING AND CLOSING SPONTANEOUSLY, CAR WOULDN'T GO INTO PARK MODE, ENGINE WOULDN'T TURN OFF (FINALLY DID AFTER PRESSING AND HOLDING IGNITION MULTIPLE TIMES FOR SEVERAL SECONDS). AUDI DEALER STATES MODULE UNDERNEATH THE REAR SEAT IS CORRODED. IT'S A BRAND NEW CAR (LEASED < 3 MONTHS AGO). TERRIFIED TO DRIVE IT AGAIN AS IT APPEARS TO BE A SAFETY ISSUE AND IS HAZARDOUS FOR MY FAMILY.

To see whether a recall is still open on your car, enter your VIN at nhtsa.gov/recalls (U.S.) or your registration at check-vehicle-recalls.service.gov.uk (UK). Had a safety problem? Report it to NHTSA; complaints are what trigger investigations and recalls.
