My 2023 GMC Acadia experienced a complete electrical system failure while driving on an interstate highway. During the incident, the vehicle lost all electrical power, including hazard lights and steering assistance, and could not be shifted into neutral. The vehicle became immobile in active traffic and required police-ordered towing due to safety risk. This incident was the second alternator failure within six months. The second failure involved a GM-installed replacement alternator that failed prematurely. Both incidents required towing, and the second created a significant roadway safety hazard.
Backup camera failed. Same issue on 2021 Acadia SLT Needs to be investigated on 2023 models
On 11/26/24 my wife was running errands in her vehicle when the power shut off and killed the car. She was in the left lane of a busy state highway. She was able to coast off the road slightly before the vehicle came to a complete stop. The dashboard said to press brake and start button, but the car would not start. The vehicle was also stuck in drive and would not switch to park, neutral, or any other gears. Police came and had to push her vehicle with theirs into a nearby park lot so a tow truck could pick it up. It is currently at a GM dealership waiting to be looked at.

Purchased Vehicle Oct.21 2022. In first week, vehicle left my wife stranded twice, and myself once. When error occurs, vehicle goes into limp home mode and cluster illuminates all lights, says serivce brakes, transmission, engine, fuel tank reads "E" (when is was just full), PRNDL buttons are flashing and will not allow park, does not respond to throttle inputs... only way to be not stranded as the vehicle will not restart is to disconnect battery or wait 15-20 minutes as the vehicle seems to incorrectly "heal" its errors and allow the engine to restart. I noticed this when the tow truck came to pick it up, and he "drove" it on to the flat bed. 45 Diagnostics showed up on the scan tool, all relating to CAN bus communication. My concerns are the following: 1. How can a 2023 vehicle with <400 miles leave some one stranded 3 times because of a CAN bus comm error? There is an electrical gremlin (likely from lack of quality control) causing to leave a customer to having to limp to the side of the highway. 2. Why is the error able to incorrectly "Heal" itself, ie. the fault reactions seem to debounce and allow engine to restart (as mentioned prior) after a certain amount of time. This only leads to potentially putting the customer back at risk as they just were. 3. GM dealer is yet to start troubleshooting, its been 2.5 weeks. Claim is that they "need a transmission guy to look at it since the codes causing the check engine light are transmission module". Although, the vehicle has approximately 45 active codes, relating to many different modules and all pointing to CAN bus error. The vehicle has an electrical issue, causing my wife to get stranded. first warning on cluster before being stranded : "Service: Transmission Now Unable to shift Soon. " What does this even mean???? this does not tell me, what the problem is, and what I should do about it. I am an experienced OBD Engineer from an auto OEM and this does not follow best practices. Please help.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
