The ACADIA 2020 while in slow motion approaching my private condominium parking spot, accelerated autonomously and then slammed into the cement wall. Airbags deployed, no warning of collision, seriously damaged both car and cement wall. No bodily injuries. I researched the possible cause coded P2138 which involves the drive by wire sensors which connect the throttle pedal and the CPU that controls the mechanical throttle gas system. That might be the cause of the autonomous acceleration like explained about the P2138 sensors issues.
SQUEAKING NOISE FROM THE FRONT END DRIVER SIDE JUST APPEARED WHILE DRIVING. DRIVER SEATBELT WILL NOT LATCH ON THE FIRST COUPLE OF TRIES.
