1215 miles . The adaptive cruise control system was acting sketchy. It failed to maintain proper distance and speed between the vehicle in front. We took it into the dealer who said that the sensor had failed on this brand new vehicle and they replaced it on 2/12/2025. After driving the vehicle when we got it back. There ds not seem to be much different. The van tends to accelerate extremely quickly only to get behind the vehicle in front sometimes not keeping proper distance with the way it’s set, as well as waiting to the last possible moment maybe 2 or 3 car lengths to break which is extremely scary. Sometimes the warning comes up that says break break . Even with the system said it maximum a car cutting in the system is extremely slow to react. This has led to numerous close calls of rear end collision. We took it back to the dealer on 2/24/2025 1802 miles, who said they couldn’t find anything wrong.
