2022 GMC Acadia Lane departure Problems

“Driver side blind spot monitor fails to detect vehicles. I first became aware of the problem as I was entering a freeway and nearly caused an accident. I scheduled service at my GMC dealership but had to wait two weeks for an appointment. The system stared working again just before the appointment and the dealer service department could not find a problem. My neighbor's 2021 GMC Acadia has the same issue. Does somebody have to die to correct a safety defect?”

“Electronic thermostat fails. Which causes steering assistance reduced drive with care to illuminate. Temperature gauge drops to cold. Air conditioning no longer operates.”

“Received message dash stating Steering Assist is Reduced, Drive with Care . The AC turned off and temp gauge went to C . Noticeable difficulty steering at both highway speeds and on city streets. While driving to auto shop the message disappeared, AC turned on and temp went back to normal. About and hour later while diving on the interstate it happened again and steering was difficult again. This first occurred on August 24, then again on September 12 and October 21 and again on October 25. No consistency as for time of day or outside temp. …”

“The cruise control does not down-shift the vehicle early enough. it does not react for the first 6mph over set point and then when it downshifts it only downshifts one gear. The vehicle exceeded 10mph over set point on a 6% grade and brakes had to be engaged because manual limit did not perform as intended at the moment. This might have been ok in the 90s but all other cars I had handled this much better in last 15 years. The lane keep assist attempts to drive the car into oncoming traffic when there are road patches present in the lane.”
