2020 Audi SQ5, 3.0T EA839 engine. On 9/22/2026 an independent repair shop inspected the vehicle and found engine coolant pooling in the engine valley beneath the coolant module (integrated water pump / thermostat housing). The leak is internal and was not visible from outside the vehicle: no coolant on the ground and no warning light before the shop inspected it. The area was wet and coated with residue, indicating the leak had been active for some time. The shop confirmed the leaking coolant has contaminated the PCV valve and vacuum hose system located in the same area. Repair estimate is approximately $4,600 to replace the coolant module, PCV valve, and vacuum lines. This failure pattern…

My 2020 Audi SQ5 (3.0L turbo V6, EA839 engine) experienced premature water pump failure at 64,361 miles. Coolant leaked into the vacuum system, damaging the vacuum unit and related components. Failed parts are available for inspection. Safety Risk: Loss of coolant circulation causes rapid overheating and risk of sudden engine failure at highway speeds, creating a collision hazard. Coolant intrusion into the vacuum system can also impair brake booster function, compromising stopping ability. Confirmed by Dealer: Diagnosed and confirmed by Audi Reno Tahoe (Reno, NV) on April 9, 2026. Written estimate #XXX documents replacement of the water pump, pulley, valve, vacuum unit, hose, and tank â…

I recently purchased this vehicle 8/5/23 and since then the pre sense function has activated itâs jarring emergency breaking three times. Once it happened to me backing out of my driveway without any obstruction, another with my husband backing out of a parking spot, and then most recently today with me as a driver going about 35 mph where it âsensedâ a vehicle next to me about to change into my lane but changed their mind. Even if the vehicle next to me changed lanes to go in front of me, there was plenty of space and having the emergency pre sense braking created a more unsafe situation with the vehicle behind me potentially rear ending me. I contacted the local Audi dealer and they…

I have had multiple instances of the emergency breaking applying improperly. On at least two occasions the rear backup/parking sensors detected some sort of object when one didnât exist and abruptly engaged the breaks despite there being no object behind me. On one occasion I had a passenger who witnessed the behavior. On another instance, and the one that concerned me, the front collision indicator detected something non-existent and abruptly slammed on my breaks while I was driving 70mph on a 3 lane highway. There were no objects or car in viewable distance at all. The abruptness, lack of warning, and breaking power sent my car out of control across all three lanes and nearly into a…

WHEN USING THE LANE-DEPARTURE AND 'STEERING CORRECTION' SYSTEM THIS VEHICLE WILL ATTEMPT TO SUDDENLY, SHARPLY, AND DANGEROUSLY CHANGE LANES. THIS MORNING (8/26/20), WHILE TRAVELING ON A FOUR LANE DIVIDED HIGHWAY WITH CRUISE CONTROL AND LANE DEPARTURE ACTIVE, THE VEHICLE JERKED LEFT INTO A TURN-ONLY LANE, OVERRIDING MY MANUAL STEERING OF THE CAR IN THE STRAIGHT TRAVEL LANE. HAD ANOTHER CAR BEEN IN THE TURNING LANE WE WOULD HAVE NEARLY CERTAINLY COLLIDED, AS MY CAR WAS AT LEAST 30% INTO THE LANE BEFORE I COULD REACT AND BRING IT BACK INTO THE CENTER LANE.
