Sold 2018 GMC Acadia by LEE GMC in auburn. Acadias shift to park was defective, dealership replaced before sale did not disclose, shift to park and transmission malfunctions occurred. I returned Acadia to the dealership several times and they would never properly fix or address my concerns now my vehicle is unsafe to drive. I have documentation to support the claims in my letter, I can send as well if youâd like. Thank you Will send attachment
