2018 Audi SQ5

During a rainstorm, water drained from roof drains that are apparently supposed to be cleaned & maintenance done by dealership on a regular basis but were clogged due to them not being any maintenance done. Water shorted out the entire control module for the entire vehicle computer after leaking into the rear inside behind hatch where battery and electrical components are located rendering the vehicle dead and undriveable on the side of the road. By the vehicles complete electrical system being rendered dead, this puts those in risk of accidents and is not covered as a warranty item for an issue that is well known according to dealership on their entire line of SUV products for the last decade. They wanted more than the SUV was worth to replace the computer control module, body wiring harness, and drain tubes that were clogged, but stated it happens all the time and is well documented by all Audi dealerships.

The Forward Collision Warning system in my 2018 Audi SQ5 is meant to autonomously apply the vehicle's brakes in the event the car senses an oncoming forward collision. At least five different times over the past five months, my vehicle's Forward Collision Warning system activated and applied the brakes at seemingly random times when there was no possible threat of an oncoming forward collision because, in each instance, the vehicle was being driven on multi-lane highways with no other vehicles, barriers, or any other frontal hazard within a quarter-mile of my vehicle. In four of the five instances, the vehicle was traveling at speed at or around 65 mph and, when the Forward Collision Warning system was activated without warning, the vehicle rapidly its speed to below 10 mph, which caused me and my passengers to be thrown forward and our seatbelts burned our shoulders and laps. In the other instance, the same occurred while traveling 45 mph. There is no warning or indication of malfunction prior to or following these instances. I''ve run multiple OBD2 scans on the vehicle, none of which have shown any problems with the Frontal Warning Collision system, or any other vehicle system.

Two issues: 1. Phantom braking, sudden deceleration, vehicle came to a rapid complete stop on road. Audi assist light came on. Road Conditions: clear, dry, very good visibility for night conditions. 2. While driving at highway speed, i.e. 65 MPH, the transmission disengaged temporarily for several seconds and causing the engine RPM to surge. Transmission re-engaged and operation became normal.

TL* THE CONTACT OWNS A 2018 AUDI SQ5. WHILE DRIVING APPROXIMATELY 25 MPH, THE COLLISION AVOIDANCE SYSTEM ERRONEOUSLY ACTIVATED AND CAUSED THE VEHICLE TO ABRUPTLY STOP. THERE WERE NO OTHER VEHICLES IN THE VICINITY AT THE TIME OF THE FAILURE. THE CONTACT INDICATED THAT THE FAILURE ALSO OCCURRED WHILE DRIVING IN REVERSE. THE FAILURE WAS NOT DIAGNOSED OR REPAIRED. THE LOCAL DEALER (BELL AUDI, 782 US1, EDISON, NJ) WAS NOTIFIED OF THE FAILURE. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 1,500.
