Car reduced speed and the smell of gas filled the car. Car shut off. Check engine light came on with reduced speed. This is the second time this has happened. Gas leaked onto ground from car. Car stalls immediately while driving and does not allow you to press the gas to keep moving. Almost hit from behind on main street.

After vehicle acting like it isnt getting power and trying to die, I pulled into a gas station and turned it off. When I went to restart it, the vehicle kept turning over and over automatically not wanting to start and the engine light came on. I let it sit for about 5 minutes and tried again. It did same thing. I tried a 3rd time pushing the gas pedal and it finally started. I made it home 2 miles away. Turned the car off and tried starting it again with same issues.

Out of nowhere and driving this morning, my engine reduced power came on. Then I started losing power in the car then it died on me once out of nowhere. I managed to make it home an hour and a half later, but that could’ve got me killed stopped by autozone since dealerships closed today and it tells me that it’s code p228c, p0089 fuel pump. And then last night my emergency service calling came on which one I looked it up so something to do with onstar and could be a module so I’m not sure what that is. And then you add on the fact all the sudden in the last 24 hours, my screen keeps going in and out are not working last week. My volume wasn’t working. I love this car, but it seems to have a lot of issues all of a sudden and I’m fixing to be at 60,000 miles which is a big problem considering warranty will be expired. I’ve already had issues with squeaking and squealing from the windows that they claim they can’t find nothing and I’ve had to listen to it for almost 60,000 miles. I had to get this car because my other car blew up on me and I can’t afford another new car. I’ll be taking it to the dealership first thing in the morning and I hope to god that something can be fixed cause we’re in one car family.

Fuel pump module failure, there’s a recall on this part for this year model but not my VIN #.

With no warning signs, vehicle abruptly stalled while driving. I attempted to restart multiple times. Finally restarted and drove another 100ft and stalled again now with a check engine light. Made it to local shop and code p129f was found for fuel pump module. I see there is a recall on this but not for my particular VIN. Recommend expanding recalls.

Check engine light is coming on, indicating reduced engine power. Took vehicle to GMC dealer and they advised that the repair shop was getting assistance from the GMC tech line to update a module to correct the issues. I was informed today that the high pressure fuel pump will have to be replaced, along with a hose or pipe to correct the issue. The vehicle has 57k miles on it. Upon researching the issue, I found that this has been a persistent issue with this model vehicle, dating back to 2020. It appears that it has not been resolved and the vehicles could stall or stop at any time. There is currently a class action lawsuit pending on this issue. Please help, this is dangerous.

On febuary 14 2026 I was driving on the feeder of the freeway with speeds of 50 mph my car suddenly down shifted in the middle of driving started shaking real bad stalled wouldn’t start wouldn’t go in gear at all would just die and say engine power reduced. This is after it had just been at the dealership and they said all I needed was an update. It had to be towed and the dealership said it was my high pressure fuel pump had failed. They replaced it and gave me the car back. I staled the next morning going to work on the freeway going 70 mph same exact thing happened except this time I could smell gas so strongly. I had to sit on the side of the highway until it was picked up due to gas smell and fear of fire. They say a bolt broke off of the high pressure fuel pump they just installed.

I had a message flash that said the power to the engine was reduce. Next message said check stabilink ( or something similar). . It said drive with caution. I live 2 mins from my job I drove home and pulled in the driveway I then felt the car act like it wanted to shake. This was on 2-10-26 I contacted onstar asked them to run a diagnostic. The codes that came back p0016 p0089 p228d are very well known codes with many people with the same vehicle/engine that have had to replace the engine. The engines have known issues had I known that maybe I could have replaced a part or two or three or four to have a stable vehicle now my vehicle is currently at GMC dealer since Tuesday morning actually had it towed there Monday night. I called Wednesday evening they still wasn't sure the "issue". Thursday I wait until about 1pm spoke with john he said well we are pretty sure you need a new engine the mechanic is checking a few more things the car has no pressure. About a hr later I get a email and a call saying the timing chain skipped and something about the pistons and the valves and I need a new engine . John called me and said well. Ill tell you what we will offer you a brand new engine for the same price as a rebuild plus you get 3yrs 300 thousand warranty for 10,944. Give or take a few dollars. We'll first I paid like 15,500 for the car that I just litetally paid off like Jan 12026. I really feel like had GMC made buyers aware that the vehicle has defective parts/engines buyers could replace parts or GMC should be held accountable. I started googling the engine and found out that there is a class action lawsuit and a recall on " certain" 2017 Terrains depending on the VIN. Same issues my car is having but its saying my car has no recall.

The engine light came on while driving, saying “engine power reduced”. It barely accelerates, rpms go over 5, it chugs when driving. Taken to an independent service center.

Turbo boost went out in my vehicle and 3 others with the same engine, different makes/models. Vehicles were serviced at grayling car care 4430 m-72, grayling, mi 49738 (989) 348-3200. Significant power loss, sluggish acceleration, poor fuel economy, and often strange noises (whining, grinding), accompanied by blue smoke from burning oil and a lit check engine light, with the severe risk of catastrophic engine damage from broken parts entering the engine if driven, requiring prompt replacement. It's generally unsafe to drive with a bad turbo, as metal fragments can destroy the engine.

On January 16, 2026 our 2024 GMC Terrain denali experienced complete loss of power. The car was unmovable from the road, unable to shift into neutral, and unable to release the braking system in addition to the emergency brake. There were no warnings or indications prior to the vehicle's failure at 30,000 miles. The failure happened on a somewhat busy road with no ability to move the car out of the line of higher speed traffic. The cause was ultimately determined to be a fuel pump failure. The part was replaced under the 60,000 mile warranty, however, the issue relating got the fuel pump is known by GMC and has previously been litigated under a class-action suit. Therefore the "resolved" fuel pump issue remains a pressing and potentially dangerous and expensive issue.

The high pressure fuel pump, the car randomly goes into limp mode and stalls and then when cranking it back up in the middle of 635 it hesitates to start, done this 3 times already.

Drove car approximately 15 miles. Parked car. Car would not turn off. Message- transmission/park. Wouldn't car stayed neutral. Had to call wecker to take dealership. . . . Diagnostic solenoid valve body faulty. . . . 2019 Terrain miles 91669. Is there recall. Have more reports of issue. Should this happen with a well maintained vehicle all maintenance updated to date.

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.

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.
