There are 2 owner-reported driver assist & adas complaints for the 2018 Buick Enclavein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Was driving at 35 MPH with no other cars or obstructions in front of me and the vehicle suddenly slammed on the brakes on its own and the throttle became inactive (would not respond to inputs). I don't know if the vehicle slammed on the parking brake or the service brakes. After 30 or so seconds everything returned to normal. No lights are illuminated on the dash, but a light did come on when the vehicle braked on its own. The light turned off before I could see what it was.
Lane departure went out took to dealer they said oh your out of warranty 3 months we can repair for 1,000 dollars I said you are crazy and walked away .contacted GM customer service said it’s out of warranty should of been recalled for their past history of problems
