Won't start and stay running.

See all problems of the 2022 GMC Terrain 🔎.

Since purchase, this vehicle has consistently had an issue with the fuel system. When I call GMC they state only use no ethanol fuel. I wouldn’t have bought this car if that was the case. The dealership never said that when I was buying it. We replaced the entire engine for $11,000 because of a torn radiator hose, overheating and cracked a gasket. Now, the car is refusing to drive, giving engine power reduced.

A diagnostic test was ran on my vehicle and the only code that came back was issues with my fuel pump system. A recall for the issue is in place. However, my VIN number is not included. I took the vehicle to the closes GMC dealer and they replaced the fuel pump module. Within 2 weeks, the engine light came back on. I contacted the dealer and was instructed to keep driving the vehicle, the vehicle maybe resetting itself. I did and the engine light went off. Within 2 more weeks, the engine light came back on. I took it to the dealer and now they are telling me I need a new fuel pump. This leads me to believe the problem was not fixed and anything related to the fuel pump should have been examined and/or fixed.

My car has started stalling and dying when I slow down, take off or when idling. No power when accelerated, and the smell of exhaust comes into my car. I was making a turn from a red light and my car spit, sputtered, and died right in the middle of the busy intersection. I was almost hit from the rear and another car had to go into on coming traffic to avoid t boning me. I took it to 2 different places to get a diagnosis reading and both places said it was a catalyst problem, and I was told that there was a recall about that because of engine oil clogging it up. My car has been using more oil than usual here lately and im guessing thats why. Now, im afraid to drive anywhere because I don't feel like it safe and the fact that my car doesn't run good enough to drive. I was told by more than 1 person that knows mechanics, that its a issue with the catalyst and that it had a recall on it but I never received one. This is a very concerning safety issue, and one that needs immediate attention before someone gets badly hurt (or worse) because of a bad car part . My car is literally just a lawn ornament now until I can get this issue resolved. I need my car to make a living and support my family. Please, get the recall letters out and get this fixed before someone loses a life.

I have had 2 different instances where my vehicle stops in the middle of a busy intersection or traffic and have no warning what so ever. Vehicle just shuts off and I am not able to turn back on to move out of the way. First time I got it repaired it was related to the fuel pump and now I am waiting to hear back from my mechanic to see what the issue is but so far it is an indication of the fuel pump as well. Both times I required help from law enforcement because vehicle shut off in the middle of the road and safety to myself and other drivers was an issue until tow truck arrived to move my vehicle.

I was driving down the hwy and all of a sudden the car went into reduced power mode and the dealership is saying it’s a high pressure fuel pump which is not covered under the standard warranty my vehicle only has 46000 miles fennigan GMC rosenberg TX.

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.

While driving several times smelt gas and car cut out engine came on and car stopped mid driving multiple times. Says they replaced fuel pump reset car etc.

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.

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.
