NHTSA Complaint #11501399 — 2017 GMC ACADIA

GM put out notice in April 2019 stating side blind zone alert message due to water intrusion May cause issue with driver interface functions. Do not take your vehicle to dealership unless you believe there is a problem. Reimbursement by 4/30/2020 6 years 80,000 miles. Vehicle stopped working while parked in driveway. No start, no cranking, warning lights for security lock out, side crash detection, tire monitoring service and airbags displayed. Dome light for front door did not work while second row lights did work. Lift gate would not open. When stating issues to dealer prior to service were told they had not heard of anything that would stop a cars engine from functioning. Dealership repair stated this was due to rear blind side detection module and that the module shorted out cause all other circuits to go to ground, yet no fuses were blown. Starter fuse and relays were good. I asked dealer if this could have caused my car to stop while driving and they answered yes. Have corroded module and wire loom referee to as kit. Was told no way to circumvent system other than replacement.
