In addition to our complaint #11608543, filed on 8/14/2024, we are submitting a new and different safety concern today. While driving our new 2024 Audi Q5 with the adaptive cruise control set at the speed zone limit (55 mph), the cruise control adjusted itself down to 20 mph. The adjustment from 55 to 20 is sudden and extremely abrupt with some braking being applied. No advanced warnings or discernible causes for the speed reductions were observed. If another driver had been following us, we likely would have experienced a rear end collision. We have experienced this malfunction on [xxx], east of carroll, IA, and 1 to 1-1/2 miles north of [xxx], traveling in both the north direction and south direction. We have visited with the dealer numerous times. The dealership has hooked the vehicle to a diagnostic device and has reported to us that "the vehicle is performing as intended". We have submitted a claim with national Audi customer service representatives and they ruled that "if the dealer says that it is performing as intended", they have to deny our claim. Initially they offered "a gift" in compensation to us. We vigorously refused and stated that our goal was to have the vehicle fixed so it works properly or to have it retired from service before someone gets injured. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
We were driving on [xxx] at the posted speed limit of 65 mph. The adaptive cruise control was activated and the predictive control turned on. We drove past a [xxx] sign and the car abruptly decreased speed down to the twenties. Had another car been following us, we could have been rear-ended. We soon encountered a speed sign posting a 65 mph limit and the car quickly accelerated to that speed. We felt totally unsafe in this surprise car behavior. This car behavior has happened on numerous occasions, as we travel that area often. We have had numerous discussions with the Audi dealership and they say that they cannot find cause/offer help with our safety issue. We have several videos documenting this safety issue.
