Cruise Control problems of the 2016 Chevrolet Malibu

My car won't shift into park sometimes and the suspension is making a poppin noise and my cruise control is not working.

Adaptive cruise control which controls vehicle speed to ensure safe distance stopped working rendering cruise control inoperable. This also caused the forward crash avoidance to not work. Vehicle trouble code uo269-00 stored which resulted in replacing long range radar module to correct for $1055. 00.

Tl- the contact owns a 2016 Chevrolet Malibu. The contact stated that while driving 70 mph with the cruise control activated the vehicle failed to stop or slow down when the driver pressed the brake pedal. The contact had to drive on to the shoulder at speeds of more then 55 mph in order to avoid crashing into oncoming traffic. During the incident a 911 call was made and police responded by pushing the vehicle into a median in order stop it and prevent the vehicle from crashing into other vehicles ahead. During the incident the driver indicated that the emergency brake did not operate and the stop/start button was pressed but did not turn the vehicle off. The vehcile was towed to the local dealer bale Chevrolet(13101 chnal pkwy, little rock ar. ) who diagnosed that the failure was caused by a failed engine vacuum that had broke and caused the braking system to fail. The vehicle was not yet repaired. The manufacurer was notified of the failure(case 9-531-1269174) but no assistance was offered. The failure mileage was 95,000. Jft.

When I was resuming adaptive cruise control the vehicle took off after a semi tractor trailer that was in front of me; I had to brake hard to avoid from hitting the semi truck. I was traveling about 55 mph at the time this incident happened & it has happened two more times after that initial incident. Then it stopped working and I had to take it in to the dealership. They said there was no recall on the vehicle & did a recalibration on the front camera & long range radar modules.
