The “Active Assist” features of the vehicle [Blind Spot Assist, Braking Assist, Distance Assist, Emergency Stop Assist and Lane Change Assist - was not able to check all of these above because of the selection limit] have repeatedly and randomly become inoperative while I was driving the car. I have expressed my safety concerns with the service department and management of the dealership that sold me the car. While they have returned the car to me with the malfunction temporarily cured, it has recurred on more than three occasions, sometimes “fixing” itself and other times requiring dealer intervention. The dealership cannot assure me that it is fully and finally “fixed” and I have no reason to believe that the issue will not recur as it has so many times in the past. The dealer also refused my request to say it cannot be fully and finally fixed, but their offer of $50,000 for this car (less than half of the total purchase price for a car with only approximately 14,500 miles) on a trade for a used 2022 model priced at $110,000 is some indication that they view my vehicle as flawed. I do not feel safe in the car and their offer requiring me to take a substantial haircut on this purchase is not acceptable, particularly since they cannot (or will not) confirm one way or the other whether the issues are fully and finally fixed.
