2025 Audi Q7

I own a 2025 Audi Q7 and have experienced repeated malfunctions related to the vehicle’s driver assistance and safety systems. The vehicle frequently displays warnings such as “Driving Assist Not Available” and other safety system errors. These issues started while the vehicle was still relatively new and have continued intermittently. The warnings appear while driving and indicate that important driver assistance systems are not functioning properly. I have taken the vehicle to the dealership multiple times for inspection. However, the dealership often reported that they could not duplicate the problem or that no fault codes were found. Despite this, the warnings continue to appear and the problem remains unresolved. Because these systems are related to safety features such as emergency braking and driver assistance, I am concerned that the malfunction could create a dangerous driving situation. The vehicle has multiple documented service visits and I also have video evidence showing the warnings when they occur. I am reporting this issue because the malfunction involves critical safety systems and has not been properly resolved by the dealership.

The vehicle has adaptive cruise control with something called "predictive control." The occurrence happened on I-40 in New Mexico with a 75mph speed limit. I went to pass a semi and a pickup truck followed me into the passing lane. Both lanes were clear ahead for at least a tenth of a mile. As I got to the front of the semi, we reached an exit off the right lane. The Q7 slammed on the brakes - not slowed down, it literally slammed on the brakes. Luckily I reacted to hit the gas pedal to override the cruise control and the pickup truck driver reacted by slamming on his brakes. But a simple pass could have resulted in a disastrous accident solely because of the vehicle. I had some of these issues earlier in my trip, but not to the degree of the above incident. It was most common when passing near any intersection, including exit ramps and emergency vehicle cross-overs. An intersection icon showed up and the vehicle slowed down - sometimes gently, sometimes more forcefully. It appears to be operating within its design parameters. I reported the issue to the dealer, but I am currently across the country. I am awaiting a response. I found the settings to turn off predictive control and am testing the system to see if this works. But if the system is operating as designed, there appears to be a flaw if predictive control is active.

Often brakes abruptly. the first time the car was set at 60mph adaptive cruise control when the car abruptly braked to almost a stop on a divided four lane hwy. I reported incidents to Audi Cary & put my car in for service. they did not find diagnostic conclusion. after picking up my car the problem continues.While on Adaptive cruise control set at 62 mph abruptly decelerates to 17, forcing driver to pull into right turn lane. Again on same afternoon car braked abruptly with another car following closely behind, the driver accelerated, there was a pause where braking stopped but car did not accelerate, then the car accelerated avoiding being hit from behind. The last two incidents I immediately call Audi Cary to report the problem. I now journal all episodes of malfunction.
