The 2018 Audi Q7 has been in for service three times since I leased the car on 9/11/2017. My initial inquiry related to technology issues was back on December 22, 2017 that was shortly followed up by a service appointment. After your team assessed the issue and allegedly reset the system, I checked out of the service department, only to experience the same technology issue as I was driving off the lot. Your team proceeded to check the vehicle back in for further investigation. Aside from continued reboots of the Audi computer system or mmi system, the car would flag Audi pre sense warnings and force the car to stop in the middle of intersections, mid turn. Oncoming traffic was estimated at 150 yards from the intersection when the car jammed to a stop. The sensors appear to stop the car after identifying a false read. The car is then stalled in the middle of an intersection causing significant safety risk. Audi replaced the mmi system and the fuel tank after identifying a faulty valve. After the repairs, the vehicle continued to have the same issues. Audi was not able to identify the source of the issue and claimed that the pre sense system sensors were set to a high sensitivity. They also claimed that a pothole or a bird could set off the sensors, causing the vehicle to stop in the middle of an intersection. This seems like a serious safety issue. By the way, I was driving a loaner car for over three months while they attempted to fix my vehicle and false pre sense warnings are common.
