Two problems related to adaptive cruise control have been reported for the 2022 Audi Q7. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2022 Audi Q7 based on all problems reported for the 2022 Q7.
My wife was driving the car with the adaptive cruise control set at 72mph on 5/11/2025. The milage on the odometer was about 37165. A car was close behind when suddenly on of the systems in my car slammed on the brakes and attempted to stop the car. There were no warning indicators to suggest why this had happened. My last Audi, a 2020 a6, did this as well. It had a number of safety systems malfunctioning around the same time. At one time, I was told by the Audi dealer that the car was unsafe to be driven and it would not return the car to me. It was impounded for about six weeks as I recall. Whatever the reason, this is a serious safety issue when an vehicle suddenly tries to stop at that rate of speed on a highway with other vehicles on the road.
I drove on highway 5 south from los angeles towards san diego in the morning. I followed the traffic in the middle lane and turned on the acc, including the lane-keep assist, at the same time. The speed was set at 78 mph, but the traffic was moving faster than that. The distance was set to level 3 for acc auto brake. After passing a speed limit sign, the head-up display suddenly showed a speed limit warning light, and at the same time, the vehicle suddenly braked and reduced speed to 65 mph. The vehicle behind me almost crashed into me. The acc didn’t behave the same way as in the past, and I didn’t receive any notice from the dealer or manufacturer about this significant change. This could definitely be a major problem when using acc in traffic. For example, if the traffic is moving at 80 mph and you set acc at 80mph, when pass a 55 mph speed limit sign, the vehicle will quickly reduce speed to 55 mph, which could cause a serious problem for the cars behind.
