2015, GMC, Acadia SLT. Rear brake calipers had to be replaced out of my pocket after rear brake calipers froze and locked the brakes in the middle of traffic. This almost caused a major accident in which lives may have been lost or severe injury sustained. The rear brake calipers were inspected by a mechanic. ABS, Traction Control and Stabiltrak warning lights illuminated. Had to have the vehicle towed four times due to rear brakes seizing. Vehicle was sold to me by Posner Park Chrysler, Highway 27, Davenport, FL who did not fulfill the promised repairs and lied to BBB but researching their submitted Used Car Inspection Sheet, they destroyed the rear brake calipers when installing rear rotors and pads and never did install the passenger side fog light assembly as promised after they claimed they had ordered it and held up vehicle delivery until the evening before my departure from Florida back to New York. They were deliver the vehicle by 11:30 am, August 17, 2021 but I did not drive away with it until 5:00pm, the clock-out time for all mechanics in Florida.
