2017 GMC Acadia: won't start

Filed Aug 11, 2024 · Electrical, Fuel system · PA

I was traveling at the posted speed limit of 80 mph on [XXX] in South Dakota at [XXX] and the GMC Acadia was working without any issue when all of a sudden various warnings flashed on the dashboard with one of them being power saver mode engaged. Within about 3 minutes various other warnings flashed and the vehicle motor turned off along with all of the electrical systems. Luckily, I was able to maneuver the GMC Acadia to the shoulder of the highway safely. The vehicle would not start and for about a minute or so we were trapped in the Acadia. We could not unlock the doors or wind down the windows until I pressed the start/stop bottom several times. Onstar did not work either. Once we could get out of the Acadia, my wife called 911 and in roughly 20 minutes or so, a police officer arrived at our location. We also called AAA and had a tow truck take the broken down GMC Acadia to a garage for repairs. It turns out that the alternator went bad and rendered our GMC Acadia useless in roughly 3 minutes from the initial warning. There was absolutely none of the tell tale warnings of a bad alternator. We did not see or observe any dim lights, hesitating starts or any other things associated with a bad alternator prior to the 3 minute warning before the vehicle completely was inoperable. We are very lucky to be alive. If [XXX] was more congested with traffic at the time of this incident, we might have been serious injured if not killed. IMO this GMC Acadia is a death trap. This vehicle warns the driver when the key fob’s battery is low many weeks before it needs to be replaced. It should warn you more than 3 minutes if not several hours prior to the vehicle being completely immobilized. It should be noted that the check engine light came on several hours before this incident and I called Onstar and they ran the diagnostics and returned a P0420 code which is related to emissions. The check engine light turned itself off about 1 hour before incident. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMAT

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.

Oct 23, 2019 we were supposed to bring our car for a service because the check engine is on but before we even get to the dealer the car won't start. We have to call for a towing company. When we get there they said they don't know what's wrong. We called gmc complaint before we got an answer with the dealer on oct 30 they said its a fuel pump recall. Since then we haven't heard from them. It will 6 weeks this week. We just bought this car as certified pre owned last april 2019 now we cant't use it and no updates at all. We don't know when will have our car back.

When vehicle is shifted into park information center says vehicle is not in park and vehicle will not shut off. I have taking the vehicle into gmc service and they said it was okay to drive it and take it home. Since then we have had to get the vehicle towed back to the service dealership that said it was okay to drive because the vehicle died several times and would not start. There is a nation wide problem with this model ant the shifting not staying in park.
