2022 GMC Acadia Fuel System Problems

The Fuel Pump Control Module failed. It happened when the car was parked. The car would crank, but would not start. We were stranded far from where we live. It was hot and we had to be towed to a GM Dealership. This part could have failed on the hi-way with awful results. The Dealership verified the defective part. We have the old part as needed. Lots of lights flashed and went out. The Engine Light stayed on. The Gas Gauge was not reporting the correct amount of gas in the tank, but seemed to correct itself before the part failed..

While deiving in three lanes of traffic in rainy weather. The vehicle began to buck as though the engine was cutting on and off. No warming lights or abnormal noises preceded the event. The vehicle lost traction several times, but recovered. As quickly as it happened it stopped and normal driving resumed. It occurred 2 more times after approximately 1 mile of travel. I was able to limp the vehicle home, but once I shut it off it would not start again. I had it towed to the dealership and the service consultant informed me that it was the Fuel Pump Control Module that had failed and it was covered under warranty.

Vehicle stalled and was unable to get out of roadway due to failed fuel pump module.

My engine light came on, I took it to the service center where I purchase the vehicle. They state it is a evaporative emission canister purge pump. They state the part is on back order due to many vehicles having the same faulty part. I contacted GMC, they state the part is not available at this time. Secondly the park assist was recalled to be fixed. That part is also on back order and not available at this time.
