The upper portion of the front grille is loose and about to fall off. I know GMC has a recall on some trucks for this issue, however mine is not listed on this recall although I have the exact issue as the recalled trucks. It’s just a matter of time before this comes off driving 70 mph on the highway and could strike a vehicle behind me causing an accident. I noticed this being loose back in June 2025.

The vehicle’s shift control module in the transmission is malfunctioning. The vehicle is shifting hard and having trouble finding the gears. The safety issue is that this is a known GMC transmission malfunction with the risk that the rear wheels can lock up when downshifting in the higher gears. Sudden rear wheels lock up proses a risk to cause an accident on the roadway potentially harming the driver and passengers in the defective vehicle as well as risking other drivers on the road. No warnings were given before the malfunction. The vehicle has been regularly serviced on time and taken care of. The malfunction began and within one week the vehicle progressed to shifting so hard I didn’t feel comfortable driving it especially with my child in tow.

I received a recall notice in May 2025 for L87 Engine. To date, remedy not available. Per the safety recall letter provided, I'm notifying you that the dealer has failed "within a reasonable amount of time" to remedy this situation.

Car was parked overnight in my garage and in the morning it would turn over, but not start. Had to have it towed to my GMC dealer, but had great difficulty moving the car out of the garage because the transmission remains in PARK if the engine is not running. Had this happened on a highway while driving and without a place to safely get off the road ( which HAS happened to others who have made this same complaint to NHTSA), this could have been an extremely hazardous situation for the occupants of the vehicle. The engine will suddenly shut down, power steering is lost, and power braking will also be lost. This problem was diagnosed as a failed fuel pump module. The failed part was replaced by the dealer (GM part#13554820). The service manager acknowledged that this is a known and common issue and that GM is aware of it but has not issued a voluntary recall. The manager also advised that this part has not been updated and that it may fail again without warning. Please....this is a serious safety issue that needs to be addressed before someone is injured or killed while abandoning a car stalled in traffic that cannot be moved.

The contact owns a 2014 GMC Acadia. The contact received recall notification of NHTSA Campaign Number: 23V334000(Air Bags), and the vehicle was taken to the dealer several times for the recall repair; however, the contact was informed that the wrong parts were received. The contact was informed that the wrong color of part had been delivered. The contact stated that the issue had persisted for months. The manufacturer was made aware of the issue, and the contact was informed that the dealer would be contacted regarding the issue. Additionally, the contact stated the recall safety risk was major, and the contact was afraid that the vehicle would experience the failure. The contact had not experienced a failure.

Instrument cluster malfunction. Entire instrument cluster blacking out every 60 seconds, then rebooting nonstop while driving. While this was occurring, none of the advanced driver assistance systems functioned, nor did the speedometer or other gauges. This occurred while on a trip, and meant having to travel a long distance without having emergency braking, collision warnings or the ability to monitor speed. The car was taken to local dealer and they replaced the entire instrument cluster.
