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

2017 gmc acadia has 'shift to park' error for the last 6 mths. Will not acknowledge the car is in park and will not turn car off completely. It has caused other issues with the car like battery/car hesitating to start in the morning. Also the radio/bluetooth not disconnecting after turning car off. You have. This is a long process to get the car to realize it is in park. After turning car on and off, shifting car out of park and back into park. And also wiggling the shift gear. This after knowing it is an on hoing issue for well over a year is still not a recall and they still have not made a fix for this.

Stopped at an intersection for a red light, upon green light, accelerator tapped to enter intersection and forward collision braking system applied brakes. Nothing was in front of vehicle at time of forward collision braking system application. Tapped accelerator again and vehicle hesitated but slowly accelerated to normal speeds. The vehicle behind at the time barely stopped which would have rear-ended my vehicle and caused a chain reaction. Continued on to work, carefully applying accelerator after each stop. Very scary for the vehicle to stop in the middle of a busy intersection with traffic behind and not immediately allowing driver to control acceleration.
