Audi SQ5

During a recent inspection at Audi Chantilly (Virginia), the service department inspected cracked upper control arm bushings in the front suspension that were noted during a recent service to install new tires and perform an alignment (see attached photos. There is cracking and what appears to be some type of fluid leakage). The dealership denied warranty coverage, claiming these are merely cosmetic stress cracks. This is contrary to what the TSB for this issue instructs the dealer/technician…

Component failed: The vehicle's structural front subframe assembly has suffered severe, catastrophic rust perforation and deterioration. Safety risk: The subframe holds the engine and front suspension. It is structurally compromised and at imminent risk of snapping or collapsing at highway speeds, which would cause a total loss of steering and vehicle control, risking a fatal high-speed crash. Dealer confirmation: An authorized Audi dealership inspected the vehicle on [Insert Date from 2…

I purchased my 2018 Audi SQ5 on September 12, 2025, from Audi Denver (McDonald Automotive Group). On XXX, at 114,145 miles, the vehicle suffered a sudden, catastrophic engine failure while driving on the highway near [XXX], caused by defective rocker arm needle bearings in the 3.0T EA839 V6 engine. ​The early-design needle bearings disintegrated within the cylinder head, scattering loose metal roller bearings into the valvetrain and oiling system. This caused an immediate, complete loss of…

On July 17,2026 my vehicle suddenly overheated. All warning lights came on and I stopped immediately. The car had to be towed to North Atlanta Audi for inspection and repair. I was told the waterpump had failed and corrupted the vacuum lines. There was no symptoms or previous warnings at any time. The repair bill was going to be outrageous. The service department person contacted Audi and they agreed to furnish new parts but I would have to pay all labor cost. I had no choice but to agree.…

While driving in live traffic, the vehicle suffered a catastrophic and total simultaneous mechanical and electrical system failure. Without warning, the vehicle completely lost engine propulsion, braking assistance, and all dashboard displays. Concurrently, the vehicle suffered a complete blackout of all exterior safety lighting, including the brake lights and the emergency hazard flashers rendering the vehicle completely invisible to surrounding traffic. Prior to this complete shutdown, the…

While making a U-turn on a high-speed arterial roadway (Philips Highway) with a child passenger, the vehicle suffered a sudden, complete failure of the driver-side rear CV axle/driveshaft assembly. A loud pop occurred followed immediately by total loss of vehicle propulsion, leaving the vehicle stranded across active lanes of traffic and creating an extreme hazard for severe rear-end impact. There were no advance warning lights, messages, or prior symptoms before the failure occurred. ​The…

While driving a 2018 Audi SQ5 with the EA839 3.0T engine, a coolant warning light activated and engine temperatures began rising to 210-215°F. The vehicle was pulled over immediately. Upon inspection the coolant reservoir was found to be nearly empty with dried coolant residue on the exterior indicating an active leak. The vehicle was towed to an authorized Audi dealer who confirmed via multi-point inspection that the water pump, shut off valve, and vacuum system require replacement due to…

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…

1–2 second delay in throttle response from pedal input, followed by sudden uncommanded surge/jerk forward. Occurs when vehicle is on hold mode in a slope or in plain flat conditions at a light or a stop sign. It happens when the car is cold or warm. I consider the vehicle unsafe to drive. The cruise control also has a major problem. When activated the lane departure feature also gets activated automatically but instead of making the car more stable it moves the card left and right all the time…

The contact leases a 2025 Audi SQ5. The contact stated that the driver's side exterior rear-view mirror position was blocking the driver's view while making a left turn. The manufacturer was contact and advised the contact to take the vehicle to the dealer for it to be test-driven. The dealer was notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 800.
