Other Fuel System Pump problems of the 2021 GMC Acadia

Was driving when the vehicle engine completely lost power. Very dangerous situation in heavy traffic. Had difficulty pulling to the side of the road and ended up blocking traffic. Vehicle needed to be towed and is less than 2 years old with less than 10k miles. Diagnosis is failure of fuel pump control module. I see there is an identical GMC Acadia incident already logged by someone else and the dealer said they have seen this multiple times. After 1 week at dealer, they are unable to secure part for repair and don't know when they will. A recall was issued for other GMC 2021 vehicles for this exact problem. GMC recall n212332040: power control module may cause fuel pump failure. However this recall does not include the Acadia. The Acadia needs to be recalled as well before people are killed and the replacement parts need to be made available.

Was driving and vehicle engine dead stopped with out warning. Could not get started and had to call a wrecker to tow to GMC dealership. Were told it wasn't the first time that they had seen this. They had a part in stock to repair it. It was diagnosed as the “drivers fuel pump module” . Was surprised that there was not a recall as this could have been a deadly incident during rush hour on the roads in my area. While researching found a recall on full size GMC 2021 suvs from last year (NHTSA campaign number 21v739000) ! why is this not being dealt with on the 2021 Acadias? my daughter has one she bought the same day and now I am in fear it will do the same thing !!! no insurance issues or police issues. After engine died several symbols including engine icon came on when trying to restart. Also received an email “diagnostic alert” from on star immediately : an issue with the engine and transmission system in your 2021 GMC Acadia has been detected. Please service your vehicle within 7 days….

Fuel pump control module the fuel pump control module failed while sitting idle at a major highway intersection during the noon rush hour. All efforts to remove from the highway failed because the electronic shifter could not be moved to the neutral position and the electronic parking brake could not be disengaged. It was two hours before a tow truck arrived and traffic was backed up for approximately one mile. The vehicle was towed into the dealership where the problem was identified and the fuel pump control module was replaced. (invoice attached. ) I am unaware of any accidents related to this specific incident, however given that traffic was backed up as far as it was, it is certainly a possibility. The component was not inspected by anyone other than the dealership. There were no warnings, indicators, or symptoms prior to the failure. The same component (fuel pump control module) failed again more recently. Fortunately it occurred in a shopping mall parking lot and only caused inconvenience and delays. However, there is evidently an issues with this particular component. (invoice included to verify part failure and replacement. ).
