2019 Audi SQ5

There’s a knocking noise coming from the engine that could lead to potential engine failure. There is a known manufacturers defect in these engines. Audi has extended a warranty, but not all cars are eligible. This should be a recall because if the engine fails on a high speed through a highway, it could be a highly dangerous situation

The rear brake lights on my 2019 Audi SQ5 stopped functioning due to a failure of the Comfort System Central Control Module (J393). This defect is documented by Audi in Technical Service Bulletin 2055123/5 and earlier versions. The malfunction causes the “rear lighting warning” to appear in the instrument cluster, and the brake lights do not illuminate when the brake pedal is pressed. The issue is not related to bulbs or wear-and-tear; it is caused by a software defect in the vehicle’s body control module, which results in loss of communication with the rear-lighting system. The failure occurred at approximately 73,000 miles, but the defect existed earlier and is acknowledged by Audi in the TSB. Because brake lights are a federally required safety system, the vehicle cannot be safely operated until this defect is corrected. The dealership confirmed the issue and advised that the required repair is a software update to the control module. Audi has declined responsibility, leaving the vehicle unsafe to drive. This is a safety-critical defect involving a known software failure that disables brake lights, increasing the risk of rear-end collisions.

The contact owns a 2019 Audi SQ5. The contact stated while driving 65 MPH, the front passenger’s side wheel flare detached. The driver’s side wheel flare was loosened. There were no warning lights illuminated. The contact called the local dealer but was not diagnosed or repaired. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 67,000.

No warning lights or fault codes. Took it to Audi of Dallas and without a code they said they couldn’t troubleshoot it. The car makes a whining noise only while under acceleration and is prominate between 20-50 mph. Also the fuel gauge (electric) does not show the correct amount of fuel. I have already ran out of fuel and it still showed 200+ miles left and the gauge was still around 1/2. Also while at the dealer they replaced my motor mounts through my extended warranty and said i needed to replace the rear shocks but it wasn’t covered (3rd party extended warranty) that i purchased from the dealer i bought the car from in Austin.

The Adaptive Cruise Control erroneously detects things such as shadows when going under bridges as stationary objects positioned in front of the vehicle, and aggressively applies the brake, causing an unsafe situation. If this occurs on wintry roads or icy conditions, this could create a safety hazard, especially at highway speeds. There is also no known way to disable the adaptive cruise control during periods where this could be a likely scenario, such as certain times of the day when the sun can cast shadows into the lane of traffic.
