2022 GMC Sierra electrical system problems

“The Fuel pump modular system failed leaving me unable to start the vehicle and left me stranded in the [XXX] heat for hours. The vehicle only has 57k miles. There was a recall for this specific issue for many GM vehicles but not mine. There was no warning! It has been towed to Sheehan Buick in [XXX] and diagnosed as the Fuel pump Modular system but I am being told it is not covered under the recall.”

“The contact owns a 2022 GMC Sierra 1500. The contact stated that the vehicle intermittently failed to start and was jumpstarted on each occurrence. The contact purchased and installed a new battery; however, the failure persisted. The vehicle was taken to an authorized dealer, where it was diagnosed that a corroded ground strap had caused an electrical short to the battery. The dealer replaced the ground strap, and the vehicle was repaired. The contact associated the failure with Customer Satisfaction Program: N252515590; however, the VIN was not included. The failure mileage was unknown.”

“P2101 Reduced Engine Power Idle instabilitystruggling to idle correctly, hunting/surging slightly, and possibly going into reduced-power protection mode. While driving engine reducing power, struggles then surges forward. Ive taken it to GMC however the techs say they have to experience the situation themselves and are unable to diagnose”

“I am filing a formal safety complaint regarding my 2022 GMC Sierra 1500 Denali (5.3L engine). This vehicle has exhibited a pattern of severe electrical, fuel system, and active safety sensor failures that pose a direct threat to occupant and public safety.At approximately 4,000 miles, the high-pressure fuel injectors suffered an early-stage mechanical failure requiring dealer repair.At approximately 24,000 miles, the vehicle suffered a catastrophic, un-warned total power shutdown while driving in the middle of active, fast-moving 5:00 PM rush-hour traffic on a 100-degree day in [XXX]. The vehicle completely stalled, causing a loss of standard driving capabilities and leaving the occupants stranded without air conditioning or cabin ventilation in an incredibly high-risk, live-traffic environment. The dealership attributed the failure to the fuel pump switch/control module.The vehicle's active safety framework is deeply compromised. The forward-facing front collision camera and its integrated crash-avoidance sensors have completely failed and required a minimum of three (3) separate repair interventions, yet the safety system remains broken and unreliable.The…”

“My truck is intermittently having the camera display a warning code. While in reverse or while towing and trying to use the surrounding cameras. It happens randomly and almost caused accidents in parking lots. While towing I use it for lane changes and with non towing mirrors it’s a very dangerous issue that could cause an accident especially on the highway”

“I was driving at 45 mph and all of a sudden the screens went black as if the truck was turned off and the first thing I did was turn on the hazards because I didn’t know if the engine shut off either there was on coming traffic from both my front and back so I was scared my truck shut off 5-7 seconds later the screens turned back on and everything went back to normal but I was scared that my truck just turned off I made the dealership aware of this issue as soon as I pulled over and they said they had a busy schedule and that they would try to have a manager reach out to me to “squeeze me in” Mind you I just got my truck back from the dealership due to electrical issues and service yesterday and not even 24 hours later this happened so I am upset.”
