The car went into limp mode while I was on the highway. The car said reducing engine power and then I couldn't go the speed limit I had to drive well under the speed limit and pull off the road as soon as possible. I brought it home and water came pouring out the intercooler after looking online. I found out this is a known issue for this vehicle.

2020 GMC Terrain. Our fuel pump control module (fpcm) unexpectedly failed after driving a short distance. Vehicle stalled without warning on the street and was unable to be started again. This could have resulted in a crash and/or injury to other people in the area. An independent service center suspected an issue with the module but was unable to make an official diagnosis. The vehicle was towed to the local GMC dealer who confirmed the fpcm failure and needed to be replaced at a cost of $850. There were no warning indicators prior to the incident and the vehicle's display only showed "battery saver mode" after stalling on the street.

My cars breaks failed by a vacuum pump failer and I almost died on the a hill going home.

I was driving the vehicle on the highway the cruise control was on. All of a sudden I got a warning on vehicle info panel that stated vehicle power is reduced. The vehicle decelerated on its own and I could not accelerate past 55. The check engine light came on. I pulled off the road and turned the vehicle off. After about 10 minutes, I started the car back up and proceeded down the highway at normal speed. The check engine light remained on. I stopped at a Chevrolet dealer service center in ft stockton, TX, to have the vehicle looked at. They could find no error codes and could not duplicate the problem. I was sent on my way. This has happened multiple times while driving on roads in my area. Mostly while on the highway.

The car was at a red light so it automatically stopped. When the lights turned green, I removed my foot from the break and the car would not move. I had to call onstar for roadside assistance and they called the police to make sure I was safe and that traffic flowed safely. My car was towed to the dealership after they tried to start the car by the key and my jumper cables. The car would not start. The dealership is unable to start the car as well and they are saying that the issue with the fuel pump is not under the most recent recall for my VIN number. I was able to locate the recall for the same exact issue that I’m having under my VIN number on the GMC website. I have filed a report with the GMC manufacturer to try and get this issue fixed. I have brought this car in multiple times to the dealership I purchased from and an additional dealership to show them the issues that I have been having with this car starting and stopping, I could have been ran over by a public transportation bus today.

Car reduced speed and smells of gas. Will not crank and will stall immediately and just stops immediately. Car has only 30,000 miles and it has stalled out for the second time with the same issue. The first time the car stalled on the freeway and I was almost hit from the back. This second time reduced speed and quickly shut off on a main street and was almost hit again. Car does not allow you to press the gas and coast during the incident.

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.

Vehicle struggles to shift from low gears; seems to completely miss 3rd gear. Codes from maintenance indicate tcc slip.

From a complete stop my car refused to accelerate no matter how much I pushed the gas pedal. I was pulling into traffic and was on a hill so my car rolled forward naturally into the road but would not respond to the gas pedal. The rpms didn't move, the car had power, I tried putting it in reverse and then back into drive. Nothing worked for a solid 2 minutes at least. Then all of a sudden it registered and worked. I was almost t-boned from a car coming through the curve but luckily, they were able to go around me in time. This put me and my small daughter at risk of being severely injured from a malfunction that I can't recreate to show the technicians. Since this incident, it has happened several times randomly. Sometimes I'm at a red light, or backing out of a parking spot, or pulling out into traffic. When it happens, there are no codes thrown to show any engine malfunctions, but it will not move! I've noticed more and more the lack of power when driving. Almost as if the transmission is slipping or losing power as well. I bought the car new, only have 38k miles on it, and service it every 5k miles at a GMC dealership. This is going to end up killing someone. The mechanic told me to trade it in, but I just paid it off and it's only 5 years old. There are multiple complaints about this same thing happening with tons of Terrains and there isn't a recall yet.

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 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.

While driving the vehicle the car went into limp mode and the back brakes stopped working. The car had to be drifted into a parking lot. The vacuum pump malfunctioned and has damaged the engine. If it was me in the driver seat instead of my partner, the incident would’ve 100% been an accident. The car was really unable to be controlled and we just happened to have that space that was empty to turn into. The car gave code when this happened. When getting a tow the car also wouldn’t take itself out of park or start to go into neutral to move the car to get it towed. Nothing is working with each other anymore and we were on a busy road of people when our brakes just went out.

While driving the fuel pump failed and started spraying gas everywhere in the engine compartment.

I have been having intermittent problems for well over 1 year with my vehicle not accelerating. I try to accelerate from a stop, the vehicle does not respond. I have the accelerator pedal pressed to the floor nothing happens for 10-15 seconds, then vehicle will lurch forward and start responding. This has happened several times as I am pulling into traffic. Major safety concern that could cause severe injury or fatality. I also have other issues with vehicle not shifting gears, engine feels as though it is skipping while driving. I have taken this to the dealership and was told that they could not recreate the issue. No engine code or service lights have ever displayed. Dealership told me is can't be anything major since there are no codes or service lights. Currently have 72,000 miles, did purchase an extended warranty. I have seen many complaints of this same problem from other Terrain owners. GMC needs to fix this problem before someone is killed in a collision because their product won't accelerate.

Car quit while driving could not control stopped across 2 lanes of highway almost was hit by big truck. Car would not start or go into neutral. When car almost started I put it into neutral and was pushed off of highway. Dealer towed car and replaced fuel module at 25423 miles.

I purchased this in March of 2025. 2 or 3 weeks after I bought this I took it to an oil lube shop and they said there was not any oil on the. Dip stick. Also I started noticing the car being jerky while driving and when shutting it off it sputters. I took it to max motors, a GMC dealer for a diagnostic check because it uses a quart of oil a week. They told me the high pressure fuel pump is bad and the piston rings were no good. This was on the 18th of June. I had taken it to the dealer I bought it from and complained about the problems, but he wouldn't do anything about it . The warranty was good at that time. Max motors told me it would cost me about $5000 to fix it which I don't have. I read that there was a recall on these cars with a 2. 4l engine for these problems.

My GMC Terrain was stopped in traffic at a red light. When I stepped on the gas pedal to proceed, the SUV shut-down. Could not move SUV in traffic. Called police and SUV was towed. SUV towed to GMC dealer. The k111 fuel module was causing the problem. GMC dealer repair shop removed and replaced the k111 fuel module. They claimed SUV is ok. I don't trust this SUV any longer. I read of similar problems with 2022 GMC Terrain and the fuel module defect causing the SUV to shut down. This is a safety hazard to the driver and other vehicles on the highway.

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.

Throttle position system all of a sudden went bad. My 2017 Terrain started shaking. I was holding up traffic. The sun couldn't go over 5mph. I've read online where this is happening alot in 2010'2017 GMC Terrains.

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.

5. 25. 2025 - car shut down while at a busy intersection. Called amherst police due to location and how dangerous the intersection was. Family member needed to jump start the vehicle. Vehicle started before police arrived. Drove home. Called police to let them know we were no longer at the busy intersection. 5. 26. 2025 took out battery to check charge at auto store - tested good - 82%. Re-installed battery went to get gas thinking that may be the issue, low on gas, not the case the car wouldn't start at the gas station. Family member needed to jump start the vehicle again. Drove home, called dealer, taking to dealer next week 6. 4. 2025 due to availability of service. There were no warning lights prior to stalling out both times. This is very dangerous. We are afraid to drive this GMC 2020 Terrain.

Driving on slightly uphill 55 mph highway, vehicle started jumping & losing engine power. Engine light came on, I made it to the top as it was slowing down. Pulled off to the side. Put it in park for a minute. Message showing on dash read - acceleration power reduced. Drove it on home (engine light stayed on) parked it & had it towed to dealership the next morning. Got a call from dealership the same afternoon saying the vehicle was ready to be picked up. Picked up later in evening from dealership. They left keys & paper in car for pick up. We still tend the paper left it in the box showing we picked it up. The vehicle drove good back home. Drove it the next day, as I was pulling out from a stop sign, it started jumping again for a few seconds. Got home & had my husband to drive it, as we were coming up a small hill, it started jumping & losing power again engine light was blinking at this point. Dash board read engine power reduced. My husband kept on the accelerater & when we got on top of the hill engine light went off & we drove it back to the dealership & left it to be checked again. They kept the vehicle for 7 days & said they were not able to find concern. We picked it up again. Drove it back home without any incident. It has been parked since we got it home.

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.

While driving 40-45 mph the engine light came on and 50% loss of power was displayed on screen. Thankfully I wasn’t far from home and was in limp mode for the last 2 miles. The mileage of vehicle is 42,000 miles. The codes are reading low fuel pressure and faulty fuel pump. Any help would be appreciated as this shouldn’t be happening to this new of a vehicle.

At stop light turning right, the car stalled, cut on and cut back off, cut on and back off with about 30 cars behind me. Sputtering. On the dash board it said “engine power reduced”. I had to be pushed out a main highway by police, and thankfully my 6 month old daughter wasn’t in the back seat. I have had this car 12 days with 48256 miles on it. I’m extremely concerned with the safety of this car. And when towed was leaking gas like fluid.

Having problems with fuel system.

Vehicle stalled while stopped in middle lane during rush hour traffic. Vehicle would not start, and could not be put in neutral to be pushed to side of road. Vehicle was towed to repair shop where they needed to replace the fuel pump control module. The automotive repairmen stated they have seen this with multiple GMC vehicles and they do not understand how it has not been recalled yet because, as they stated, it is going to get someone killed one day.

1st time - rear main seal blew out & engine lost all of its oil causing rocker arm to break & chains to slip-vehicle sputtered & died while driving down busy street & would not restart - my safety & safety of others driving behind me were at risk for causing a rear end accident and/or pile up crash - no warning lights or sounds alerted me - dealership told us general motors is aware this is/has been a problem with 2017 Terrain vehicles especially those driven in midwest states due to colder temperatures - the intake manifold vent hole is not large enough to let air out, so it plugs up & causes pressure to blow out rear seal, which causes oil to leak out and engine dies. When replaced with a remanufactured engine intake manifold vent hole was not drilled out causing it to happen again 2nd time - when leaving parking spot at work noticed oil puddles underneath my vehicle, I checked my oil, it showed full, I was concerned, drove to nearby last place I got my oil change. They informed me that all the oil had leaked out and showed me the bottom of my vehicle oil covered the front to the back of my vehicle. They also said that I was extremely lucky to get to shop before engine blew and stopped dead. Again my safety and safety of others behind me could have been a rear end accident and/or car pileup crash - again no warning lights or sounds alerted me - shop personal told me general motors is aware this is/has been a problem with 2017 Terrain vehicles especially those driven in midwest states due to colder temperatures - even though the repairs where done by a certified dealership the first time they replaced with a remanufactured engine but failed to drill out the intake manifold vent hole bigger so this would not happen again but it did. General motors cannot just sell vehicles it has to stand behind what they sell which in my case they have not. Due to gm lack of concern, recalls, reimbursements, lives have been and continue to be at risk.

Consumption of oil! I got my oil changed January 1, 2025. It is now February 1. I have driven less than 500 miles. I had no oil. I have no leaks or anything wrong. The car just consumes . I have had to have 6 oil changes in the past 3 months. Shop after shop. Has said it just consumes oil and this vehicle is trash. I noticed there was also a lawsuit against it. If you do not put a recall out on my vehicle ASAP, I am going to file a personal lawsuit and sue the hell out of you! for your scam! somebody better give me a call immediately. Or set me up at my local GMC dealer to fix this issue. I better be expecting a notice in my mailbox or an appointment for a free fix and this better be a recall immediately! or you’re asking for another lawsuit! I was told my car could blow up. With my kids and it could kill us! you better fix this immediately!!!!!!!.

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.

Gm flier pip6071a - continued engine misfire/chugging/buck/skip under load, going up hills, trying to pass, etc. Was taken to shop January 2025 ~90,000 with these symptoms. Charged for spark plug replacement (visit 1). Taken back January 2026 ~150,000 miles, charged for ignition coil 1 and spark plugs. Immediately returned as problem persisted, spark plugs replaced (visit 3). February 6 2026, same problem as before, spark plugs replaced (visit 4). February 18 2026, currently in shop, problem persisting, trying to say it is the other 3 ignition coils, even after I requested they check O2 sensor and inspect catalytic converter.

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.
