Thermostat of the 3.6L LGX engine of General Motors fails. This causes systems to run radiator fan full speed and GMC Certified Service Center said can cause the engine to over-heat and damage. GMC Service center said that entire Thermostat unit (box) needs replacement and due to its location in the engine, it will take 6 hours of labor. They also recommended to flush the coolant and refill. If I google for this issue, its reported numerous times on Acadia forums and seems like a very common issue.

Please have GM also cover costs of folks who have already fixed this issue with their own money, since the cost of fix is very very high. Thanks

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.

Vehicle went on fire in or near the engine compartment - the entire front end was burned and car is a total loss. I was in the vehicle driving home with my children (a 5 min drive from their school) and we smelled what we assumed was a a fire pit or fireplace burning nearby; we got out of the vehicle, within 90 seconds there were flames coming out of the hood. Car was well maintained and received nearly all service at the RVC GMC dealership it was purchased from. Vehicle was also still under the warranty we purchased.
