My wife was driving down the road and all of a sudden the car just shut off and wouldn’t start back up. She called me and I went to her and tried to get the started with no progress so I called a tow truck to come pick it up and come to the mechanic shop to have it fixed. They run a diagnostic test on it and it was the fuel module. Called the gmc in my town and the said it was not covered under warranty or there wasn’t a recall on it either. W needed my car fixed so I called around to find a fuel module and finally found one in north Myrtle Beach. I had to go and pick it up around 75 miles from where I live and bought it back to the mechanic. He put in on and that fixed the problem. A lot of the 22 Terrian’s has a recall but mine doesn’t. I would like to know why mine doesn’t and it only has 53,000 miles and mine falls in the same category as all the others. I think I should be reimbursed having to pay to have mine repaired.

My GMC Terrain started, but then stalled as I tried to pull away from the curb & drive. When I tried to restart it, it turned over but would not start. My AAA Autoclub servicemember used his "check engine" interface machine to determine that the fuel pump module was not communicating with the car, though there was half a tank of gas. This issue has been a well published problem with this year, make & model online, but GMC is not including my VIN# in the recall. I had the car towed to my mechanic & his diagnostic tests revealed the same problem - fuel system module. I would have been in danger if there had been any traffic on my residential street. If the car had driven a few blocks & then stalled, I would have been on a busy boulevard. There were no warning signs prior to the stall. There is a "check engine" icon lit up now because it is going to require service. My mechanic can't fix it, so I need to arrange another tow to get it to a dealership service department. Thank you

I HAVE THIS 2022 GMC TERRAIN WITH 19,000. MILES ON IT. IT IS OUT OF WARRANTY BY 2 MONTHS AND NOT YEARS OR MILES. ON 6-23-23 THE VEHICLE WAS BROUGHT TO NAPELTON GMC FOR A RECALLED FUEL PUMP FLOW MODULE. IT WAS FIXED AND THE RECALL WAS CLOSED. HOW EVER NOW 9-2-2025 WITH 19,000 MILES I AM EXPERICING THE SAME ISSUE AGAIN. IT WAS TOWED TO THE DEAL AND DIAGNOSED WITH THE SAME ISSUE. THIS TIME THEY ARE NOT COVERING IT BECAUSE THE RECALL WAS COMPLETED. HOWEVER I FEEL THAT WITH ONLY GOING 13,000 MILES SINCE REPAIRED THEY SHOULD BE COVERING IT AGAIN. THEY TOLD ME THE REPAIR COST IS "TO LITTLE" TO OFFER ANYTHING. THE COST WITH THE TOW IS AROUND $762.00 . i WAS TOLD BY GM "NOT THE DEALSHIP" THAT IF I SUBMIT A TICKET SHOWING THE VEHICLE WAS REPAIRED THEY COULD LOOK AT OTHER COMPNESATION OPTIONS. PLEASE HELP. I ONLY AM ARGUING BECUASE THIS WAS A RECALLED ITEM THAT HASNT LASTED VERY LONG.

I went to start my vehicle up my two days ago (8-25-25) It made a horrible sound and just shut off. The lights on the dashboard would not go out when I turn it off. I also couldn't put in gear. It had to be towed using a dollie to the repair shop. I was told that the module fuel pump power control had to be replaced. The shop owner then went on to tell me that this very same brand (GMC), has been entering his shop at a shockingly alarming rate with this same problem. I'm not very pleased with having to have this repair done as my vehicle is no longer under warranty. It cost me $432.18. I'm not rich and am living in a time as many others are that don't have a bunch a money laying around to throw away. I find this very distressing as well as unfair to my family and I to have to have this replaced on a relatively newer vehicle. If you are aware of this problem, it out to be addressed. I as well as others should have been made aware as well. At the least, I think that I am entitled to a refund for the cost of the repairs.

I was driving down a paved road and my side airbags deployed. The gm investigation showed my car left the road way, however I am uncertain of that. There was no crash or impact or damage to the vehicle from this incident other than the airbags deploying. There is a scrape on the passenger side due to an incident in April. That is not related to this incident.

Own 2022 terrain that suddenly stalled one morning after starting vehicle with remote access before getting on highway. Vehicle cut off after 5 minutes and wouldn’t restart. Battery very strong but check engine light came on. Vehicle was towed to dealership and advise it was the fuel pump control module. No warning lights or proper failures for my vehicle.

Vehicle felt like it was running out of gas and then stalled out while driving down the road. It will not turn over and it will not move out of park. This is a huge safety issue.

Three times in one month, four months after purchasing vehicle from dealership, the vehicle stalls while driving and will not restart. After running codes, each instance prompted a P129F code for the fuel pump driver control module. After the second incident, the vehicle was inspected by a qualified repair shop and no issue or stored codes were found. When the issues occur and the car stalls, the Check Engine Light and a Low Battery warning message can be seen on the instrument panel. When this issue occurs, the vehicle's gears cannot be shifted manually. The vehicle must be force shifted by hand, via transmission components under the hood, in order to place the car into neutral.

The backup camera on my vehicle stopped working completely, displaying a blank screen. All other cameras and sensors continue to function normally. The dealership identified the issue as the camera having “shorted out” and is replacing it with a completely new unit. The faulty camera is currently with the dealership, and I assume it would be available for inspection upon request. It is being replaced and I will receive a bill in a few days (Wednesday March 10, 2025). The backup camera is a critical safety feature designed to prevent collisions with pedestrians, objects, and other vehicles when reversing. Without a functioning camera, visibility is significantly reduced, increasing the risk of an accident, especially in crowded parking lots or areas with low visibility. The sudden and unexplained failure of this system is a serious safety concern. Yes, the dealership confirmed the issue when I brought my vehicle in for inspection. They determined that the camera had “shorted out” and ordered a full replacement. The vehicle has been inspected by the dealership, which is handling the replacement. To my knowledge, no manufacturer representatives, police, or insurance agents have examined the issue. There were no warning lights, error messages, or other indications before the failure. The backup camera was functioning normally, then suddenly stopped working, displaying a blank screen. I have heard that Cadillac and GMC Acadia models have experienced similar backup camera issues, leading to recalls due to sudden failures. Given that my vehicle’s camera “shorted out” without warning, I believe this may be part of a broader issue affecting GM vehicles. If this is a recurring problem, it poses a serious safety risk and should be investigated further.

OnStar module failure Its backordered across the entire country, its only reasonable to assume it's a problem. Online information I've seen is it's an issue with a lot of vehicles

Driving 75-80mph in the freeway when suddenly the power stopped in the middle of the road and couldn’t get it to run. Thankfully freeway exit was near was able to get the vehicle to safety. Tried to turn in on again and would turn on but die down after. Had to tow the vehicle and take it to the dealership the next day. Said it was fuel pump module defect and there’s nothing I could have done to cause it. Vehicle is less than 3 years old with good maintenance

This is the second time this occurred, once in Oct 2024 and on 1/25/25. While driving the check engine light came on and within one minute the vehicle began to stall and within 20 second the engine shut off. The first time it happened in the middle of the road and the second time I was just able to turn onto a side street. In both cases the vehicle would not restart and left me stranded.

Module malfunction open-fuel pump driver control. Engine stops at any time, pressing gas pedal and nothing, the engine stops running no warning. Module has been replaced twice this vehicle should be on recall. When it happens you have no warning and no control. This is life threatening.

Engine failure at low mileage. 60,300 miles. Piston 1 failed. Broken rings. Needs full engine replacement. GM will not stand by their product and repair it.

Fuel indicator is reporting empty when car is full, and car is switching gears or shutting off by itself in the middle of driving.

My GMC Terrain 2022 has stopped working 3 times for the same issue. All those times the car was tow to the dealership to get repairs. Every time that happened was the same problem, I turn on the car and immediately shuts down. It didn’t show a warning light.

My check engine light came on and I got it hooked up to get the code of P0171 - Upon checking it was different things like O2 sensor the Mass Airflow sensor, fuel pump issue etc. I have been having issues with slight hesitation during acceleration, some jerking when slowing down (not hitting the brakes). Now the check engine light was on for one day the next day it was off. I did some research and found an article that stated that GM is issuing a safety recall for 2021 and 2022 GMC terrain due to a problem with the fuel pump module failing, not enough fuel to the engine and creating stalling risk. This was from January of 2023. It also said GM notified the National Highway Traffic Safety Administration of the upcoming recall on Jan 19th 2023 and was still pending as of Feb 2023. Also stated that GM has not yet conducted actual repairs to correct the issue. My truck, I bought it brand new on Jan 20th 2022, only 23,450 miles on it. The problem literally came out of no where a week ago. The hesitation, not being able to accelerate is very dangerous when I'm on the road, I could not get the check engine light checked out professionally because the next day it was off and I was informed that they could not do a proper diagnostic if there is no light on. Obviously there is an issue with the fuel system and I really want this checked out and possibly replaced. Not to mention my gas is also going very fast now.

Fuel pump power control module failure. Part number 13554821. On [XXX], my trip home from South Carolina to Alabama was interrupted when I stopped to get something to eat. The car would not start and I had to call AAA to tow me to Superior GMC dealership in Anniston, Al. They knew what was wrong as soon as I told them it would not start. They already replaced three fuel pump control modules that day on the same model as mine. The service department said it was a persistent problem in GMC automobile's. I am [XXX] who had confidence enough in your automobile to take a trip by myself. I could have gotten stranded far away from home. I believe that this should be a recall because this is an ongoing issue with this model. I am sure that GMC is aware of this problem.

However, this vehicle’s VIN was not included in the recall. We are very lucky that this failure did not result in a crash, and that no further incident occurred while we were stranded on the side of the highway during the night, waiting for a tow.

2nd incident, 1st incident reported: Complaint number 11570916. Was driving the vehicle and the steering wheel locked again as I was making a right turn. The service ESC light immediately came on with the T/C light on the dashboard as well. I had roadside assistance pick up the vehicle to take it to the service department because I was afraid to drive the vehicle. According to the service invoice, they were not able to replicate the problem, but I have a photo of the error code on the dashboard. I was told that they checked the brake module and reprogrammed the computers.

I had an issue with the All Wheel Drive system. The message Service all wheel drive system appeared as I was driving the vehicle. They found a rear differential module software issue 2810695. They found DTC C056D stored in rear diff control module. They programmed rear diff module and retested. Claim code is 1BYN199108119.

While driving my 2022 1.5L Turbo GMC Terrain at 65 mph with the air temperature at -2 degrees below zero Fahrenheit the check engine light came on with the error message "Engine Power is reduced." I coasted to the side of the road and put the car into park. I was 200 miles from home and after working with my insurance roadside assistance, I wasn't able to get a tow truck after 3 hours of waiting in sub zero temperatures. I called the local GM dealership in my home town to ask if I could drive the SUV and they said I could at less than 35mph. I drove 100 miles to a town where a tow truck was available. I brought the SUV to the GM dealership and they said the issue is ice and condensation in the inner cooler CAC system. They said my SUV wasn't updated for the cold weather package. I was told my engine needed a cold weather package in order to drive it in sub zero temperatures. After reviewing this issue online, I found there was a recall for 2018-2022 1.5L Turbo GMC Terrain vehicles that experience these issues but my VIN number wasn't included in the recall. I called GMC to report the issue with my SUV and after speaking with multiple people was told that it wouldn't be covered under the recall due to the "numerous factors" that determine what VIN numbers fall into a recall. My SUV has the same engine, is the correct year, and has the same engine problem as the GMC Terrains that were included in the recall. I now have to pay out of pocket for repairs and the engine fix of installing a cold weather package that is covered under the recall. I believe the recall needs to be expanded to additional VIN numbers.

I was driving the vehicle, approaching an intersection and making a right turn. As I turned the steering wheel, it locked. I kept trying to turn the steering wheel and it finally did. A Service ESC error appeared on the dashboard. The T/C light came on as well. I drove it home. The error was gone the next time I started the vehicle. The service code kept coming on intermittently. Appointment scheduled on 11/10/23. GMC service dept stated they wouldn't be checking the vehicle until next Monday, so I could take it home. I rescheduled and took it back on 11/13/23. My vehicle was there for 32 days. My safety was at risk because of the failure of the steering wheel to turn, with traffic in the lane next to me as I was turning.The service dept was able to download the error codes.Code C0800 was captured. The steering gear assembly was removed and replaced, programmed and calibrated.
