2022 GMC Sierra 1500: engine stalls while driving

Filed Sep 12, 2026 · Fuel system · MD

I am filing this complaint regarding a potentially serious safety defect involving my 2022 GMC Sierra 1500 Denali four-wheel-drive with the V8 5.3 engine. The vehicle had approximately 28,786 miles at the time of the incident. While traveling on an interstate highway in heavy traffic, my truck suddenly lost engine power. I was extremely fortunate that I was able to maneuver through traffic and get the vehicle onto the shoulder without being struck by another vehicle. A sudden loss of engine power under these conditions could easily have resulted in a serious or fatal collision. Immediately follow the incident Onstar detected diagnostic trouble code P129F The vehicle was subsequently taken to an authorized GM dealership. The dealership diagnosed the problem and replaced the fuel pump power control module to repair the vehicle. I have since learned that General Motors issued service bulletin 24 –NA-139 concerning this condition. The bulletin specifically includes 2022 GMC Sierra 1500 vehicles and identifies loss of power stalling and DTC P129F among the possible symptoms. GM states the condition may be caused by an internal short in the K111 fuel pump driver control module/fuel pump, power control module. I am particularly concerned that GM has been aware of this potential failure condition since at least 2024. A failure capable of causing a vehicle to suddenly lose engine power while traveling at Internet speeds presents amsafety hazard not only to the occupants of the affected vehicle but also to surrounding motorist. I respectfully request that the federal safety agency review this issue including other owner complaints involving error code P129F, fuel pump power control, module failures, stalling, or sudden loss of power in affected GMC Sierra and related to GMC vehicles and determine whether a safety defect investigation or recall is warranted.

Truck died while driving on a major highway due to a faulty fuel pump module. The vehicle was blocking an intersection. The vehicle could not be put into neutral without the engine running because of the electronic transmission. Could not move the vehicle out of the intersection and out of traffic. I found out later that to put the truck in neutral requires a special tool, and going under the truck to engage the bypass, which is very difficult and unsafe on a major roadway.

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 vehicle exhibits phantom electrical bugs. The MultiPro tailgate audio system consistently turns itself on while the vehicle is parked, locked, and closed, hijacking the driver's phone Bluetooth from inside the home. While driving down the road, the internal cabin radio will abruptly cut out and begin blasting audio through the exterior tailgate speakers, creating a severe driver distraction. The dealership has repeatedly dismissed these electrical safety anomalies as untraceable.3.

While driving my 2022 GMC Sierra 1500 (VIN: [XXX]) in active traffic, the 10-speed automatic transmission suffered a sudden and catastrophic internal failure. Without warning, the vehicle stalled in the middle of traffic and forced itself into a hazardous "limp mode," severely restricting my speed and acceleration. This created an immediate, high-risk safety emergency, leaving my passengers and me vulnerable to a rear-end collision before we could navigate out of the live roadway. The vehicle was towed to an independent facility (Kenny's Transmission, Repair Order #XXX) at 65,579 miles. Diagnostic troubleshooting confirmed a "Number 6 Solenoid Code" and "Internal Transmission Mechanical Failure" (3-4 races away, total loss of reverse gear), requiring a complete replacement of the transmission assembly utilizing an official GM service part at a personal cost of $6,673.10. General Motors has previously acknowledged 10-speed transmission control valve defects and wheel-lockup hazards by issuing safety recalls for diesel variants, but gas-powered models like my 6.2L L87 engine are experiencing identical, highly dangerous sudden losses of motive power without federal recall protection. I am requesting that the federal safety agency investigate this systemic failure rate on 2022 gas models before it causes a major collision.

I Purchased the vehicle on May 29, 2026 and it stated the 6.2 liter engine recall had been fixed and that I have extended special coverage for the exact issue of the recall until 150008 miles on this vehicle. On July 14, 2026 the vehicle was being driven and stalled out at a traffic light and restarted, yet within a quarter mile it stalled again at the next traffic light and became completely disabled, it would not even allow a shift into nuetral, so I had it towed less than 100 feet into the Walmart on Loudon Road in Concord, NH 03301 parking lot. On July 23, 2026 I was able to get the batter charged and attach a code scanner which showed one code (P0016). Pursuant to Recall N252494001 (which had allegedly been repaired, likely with the bandaid fix of thicker oil) any 6.2 liter GM truck with the loss of propulsion needs to be plugged into a scanner and if code P0016 is present, engine replacement is needed. Specifically noted to the recall is Special coverage N252494003 which provides the coverage to 150,008 miles on this vehicle is directly related to the recall. At the time of loss of propulsion the vehicle had 99,195 miles present on the odometer. The following day July 24, 2026 I had the vehicle towed to Banks Chevrolet GMC in Concord NH, after the vehicle arrived, I spoke with the service department, provided them with the recall paperwork and printout of the special coverage uner the vin as well as a photo of the odometer and my scanner displayining one code P0016. They then informed me it would take them until August 24, 2026 to "diagnose" the vehicle. The recall is clear it just needs a code scan if disabled. I have contacted GM and informed them of the need for a loaner as the vehicle is a vehicle utilized for business. I have since been told they will try to look at it earlier and no loaner will be offered but I "may" be able to be reimbusred $44.00 a day for a rental. There are no rentals for that price that can tow over 9500 pounds. It is unnacceptable.

I am reporting two separate stall/loss of propulsion events on my 2022 GMC Sierra 1500 Denali Limited (VIN: [XXX] ), which is subject to the federal safety agency Recall #25V274000 and GM Special Coverage XXX (L87 Engine Loss of Propulsion). INCIDENT 1 — April 16, 2026: While decelerating off a highway exit ramp, the vehicle stalled without warning. The dashboard prompted me to shift to neutral and restart. I performed a rolling restart successfully and continued driving. This stall occurred while decelerating on a highway exit ramp with vehicles traveling at highway speeds behind me. The sudden and unexpected loss of propulsion created a significant rear-end collision risk. INCIDENT 2 — April 17, 2026 (next day): While traveling at approximately 40 MPH and climbing a hill under load, the vehicle stalled a second time. The dashboard again prompted a neutral restart. This time the vehicle would not restart. All I heard was a single click from the starter, followed by a complete dash reboot. The vehicle lost all power repeatedly upon restart attempts. I was stranded on a narrow, high-speed rural road in Standish, Maine during rush hour, with vehicles passing at speed. I was in serious danger. The vehicle was towed to Weirs GMC in Arundel, Maine (the selling dealer), where it currently remains for diagnosis under RO# XXX. Both stall concerns are documented as Warranty Pay. Additional concern: Since the day after purchase (March 28, 2026), I have noticed a pronounced cold-start tick originating from the bottom end of the engine, confirmed by an independent mechanic as coming from inside the engine. This vehicle passed a Recall #25V274000 inspection on December 28, 2025 at 98,233 miles. The tick and stall events began after that inspection. I am requesting this be formally documented as a safety complaint tied to Recall #25V274000 and Special Coverage XXX.

While driving on the road the vehicle started sputtering and stalled! We pulled to the side of the road and tried to start the car but it rolled and would not start. We called a a mechanic who had it towed and found out that the fuel pump and the fuel control board had failed. Both have been replaced and the truck seems to be working again. Heard several other persons had this issue with their GCM Sierra Elevation so we wanted to report since there is currently no recall. Luckily the traffic was not going that fast or we could have had an accident and been seriously injured.

Just after merging from I-65 North to 264 East at 65 mph in Louisville KY on November 14th, the display indicated to "press start" and the engine stalled. I was only able to get the vehicle about 3 inches off of the left side of the yellow line before running out of inertia. I was stuck there for 2 hours while waiting for a tow truck. The first truck could not lift my vehicle because with the engine off, the electric shifter would not move out of park. A second tow truck was called with dolly's and then a 3rd tow truck was required to block traffic. During this 2 hour period several cars swerved left of the yellow line and I was in fear for my life. The traffic was so heavy that I was trapped between the concrete median wall and the left lane. I called 911 to ask for a safety vehicle to shield me from traffic, but they never arrived as promised.
