2024 GMC SIERRA 1500 Engine Problems

I have received the notice about the recall and now I am just worried because I have a wife and two-year-old child in my truck. I don't want the engine issue to happen while they are in the truck and increases the risk to get into an accident if the engine fails. I have tried to schedule an appointment with my dealership and from the date I received notice on 04/28/2025. They stated I have to call back in two weeks which should be unacceptable because how about if the engine fails within the two weeks and causes even more issues for me and my family. This should be approached much quicker and fix the matter asap.

Purchase the truck [XXX]. In January of 2025 it started to feel like the engine was slipping. Near the end of February, it was getting worse and the locks started locking/unlocking on their own. The vehicle stalled two separate times while driving on a main road. The first couple days of March, the car stalled, again on the road while the locks went crazy. Then, on [XXX], after I had pulled out of my driveway in my neighborhood, my car completely shut down. We had to have the truck towed to Coyle GMC, in Clarksville, Indiana. And, as of May 1st, it is still there. We have been told they need some cap for the transmission and they don't know when they will get it. They offered to give us a new transmission, but they don't know when they'll get it. I am making car payments on a car that...

I had an engine failure with a complete loss of power while driving on a state highway early on 12/13/24. No lights, hazard lights, nothing would turn on for over 10 minutes, then once started my truck said "shut off engine, low oil pressure". There was a bearing failure that sent metal fragments all through the engine. My truck went into the dealership on 12/17/24 and i received it back with a new engine on 4/18/25. It has the same L87 engine with the same recommended oil as before the recall. I asked GMC to buy it back from me because it's neither dependable or safe after what happened. I was refused without being given a reason.

On April 21, 2025 around 11pm, I was entering my neighborhood, I was slowing to a stop, the truck shut off, shifted to neutral on its own. Clusters were still on though, no error codes other than instruction to turn ignition back on. I tried for over 20 minutes with no luck. I placed the truck in park and shut it off after that I couldn't get it change back to neutral. Was on the phone with onstar and recorded it. Eventually it turned on with check engine light, made it home. On April 22, 2025, I dropped it off at Classic Buick GMC 16835 Katy Fwy, Houston, Texas 77094. Service rep informed me I will require a new engine as there are metal shavings in the oil filter as a result of worn cam shaft bearings. They have had the truck at their shop since the incident.

I leased a 2024 GMC Sierra 1500 Denali Ultimate with the 6.2L V8 engine. The vehicle experienced multiple engine-related issues over time, including stalling on [XXX], and again in early 2025. On [XXX], the engine completely failed while I was driving on the highway. The truck suddenly shut down, forcing me to pull over in a dangerous situation. It was towed to North Bay Cadillac, where they confirmed the engine needed to be fully replaced. They also stated this issue is related to a known engine defect affecting 6.2L engines across GM vehicles. The vehicle has been in the shop for extended periods and is currently undergoing repairs estimated to take over a month. GM provided a loaner vehicle after 12 days, but I remain financially responsible for a defective truck that posed a serious safety risk. No warning lights were present before the failure. I am requesting that this...

On April 23rd, while traveling, I began hearing a loud, metal on metal knock. My truck began to lose all pulling power. I had no engine warnings, no check engine lights or any other indicator of engine trouble. I pulled to the side of the road and exited the vehicle. It was then I realized it was my engine making the noise. I have since had it towed to the dealer where it sits while I wait to hear back from the service department a final diagnosis. I was told this was most likely a rod or bearing. On Friday April 25, I was told of the recall. I was told I would probably need a new engine but they haven't been instructed on what the next step would be from GM.

While exiting the highway and transitioning into a turn lane, my 2024 GMC Sierra AT4 (with 12,887 miles) suddenly and completely shut down without any prior warning. All vehicle systems—including electrical—failed simultaneously. This included the dashboard, steering assistance, and emergency lights, which significantly compromised my safety. I was unable to alert surrounding drivers or move the vehicle out of the traffic lane. There were multiple cars behind me, and I was placed in an extremely unsafe situation due to the sudden loss of control and inability to signal or restart the vehicle. I immediately contacted emergency services, and a police officer arrived approximately 10 minutes later to assist. Roadside assistance later pulled diagnostic code P0016 from the truck’s computer. I have since learned that this code corresponds to a known engine timing defect and is the subject of a recent GMC recall issued just days prior to the incident. The...

In the midst of driving my vehicle, soon after exiting the expressway. I received a notification across the dashboard stating to press the brake to start engine. It was totally confusing because I was actually driving and doing so at a speed of approximately 45 miles per hour because I just exited the freeway. Then I noticed the car would not accelerate. At that point I realized that my car had shut down on me while in the midst of driving. I had to very cautiously maneuver my way through traffic to the side of the road where I parked and called onstar for help. This was a very scary moment because I felt as if I could have very easily caused an accident and injured or cost the life of myself or an innocent person. The engine shut down was not evident because all the dashboard lights were still...

As I was driving down the feeder road of a major highway, the light (press brake to start engine) came on. I was traveling around 55 miles per hour. I pressed the brake and pressed the start button but nothing happened. At this point I was coasting as the engine had died. The radio and electrical system were fully operational. I tried restarting the engine several times while coasting along the busy feeder road. I finally pulled into the right side lane (there was no shoulder) and applied the brakes. Once fully stopped, I was not able to start the engine. I called my GMC dealer for the name of a tow truck. The tow was able to pick up my truck about 45 minutes later. I am still waiting on a new engine from GMC with no time update from my dealer. This incident happened on 03/03/2025.

Experienced catastrophic engine failure while driving down the highway. Was able to coast to a turning lane in an intersection then once I came to a stop my truck proceeded to go into park and was not able to be moved. Engine would no longer start/turn over and vechile remained in park without begin able to go into neutral so had to wait for roll back tow truck to load my truck while sitting in the middle of a busy road with no way to move.

The vehicle was towed to a local dealer, where it was diagnosed that the engine had failed and needed to be replaced. The vehicle was repaired at the contact's expense. The manufacturer was made aware of the failure. The failure mileage was approximately 6,000.

Driving on the highway, moving to pass another vehicle, engine shut off forcing me to coast to the shoulder. No warnings and didn't notice loss of power until I saw that the vehicle had been shifted into neutral. Had 2 kids in the truck and could not get GMC service department on the phone, had to walk up an onramp in order to get my kids home with me in an Uber. This is a 2024 6.2L GMC with only 13,000 miles. Service department took over a week to check initial issues, said it was a fuse block which they replaced. Did not resolve the issue, then it was the starter, which did not resolve the issue, after 2 weeks they told me the engine was locked up due to internal failure and it will be several months before the truck is operable. GM has stated they the issue needs...

Engine seized.

6.2L engine seized, same bearing issue as everyone else

I purchased the vehicle brand new in October of 2023, since then the vehicle has been to service over 15 times for engine failure, vibration while driving on the highway etc. At times when the vehicle shut down it was without warning.

My vehicle stalled while driving on the highway. It has been reported by the dealership that the engine seized, with under 18,000 miles.

After 17500 miles and 11 months ownership 6.2ltr engine stopped operations while driving, in traffic and locked up on interstate without warning. Towed to Chevrolet Dealership and disassembled, main crankshaft bearings failed.

My vehicle started rough with rattling and knocking one morning. I contacted my dealer and made an appointment. I received an appointment for about a week out and did not operate the vehicle until that day. Upon bringing the vehicle to the GMC maintenance shop, the vehicle’s engine ceased and had to be towed the remainder of the trip.

My motor seized and shut off while driving 63 mph on a busy highway going up hill. Truck made it to the top of the hill before it shut off and had to coast to a stop on the side of the road. No warning lights or anything. Rpms locked at 3000 and wouldn’t go up or down until the motor shut off. Switched itself to neutral while it was rolling still and wouldn’t allow my to put the truck in park when stopped. Finally locked itself in park and wouldn’t allow to be shifted to neutral. Dealership said the motor seized and ordered a new one but is on back order

On the morning of March 12, 2025, I started experiencing a ticking sound from the engine bay under throttle. I suspected lifter failure and decided to proceed to the dealership that afternoon for repairs. During my commute, the engine started squealing and shuddering and I experienced a severe loss of acceleration which made it almost unsafe to drive on the highway. Upon coming to a stop in traffic, the engine died. I was able to get it restarted and proceeded to continue my trek to the dealership. Upon another traffic stop, the engine died again, at which point I made the decision to exit the highway and continue my journey along the service road. Twice more the engine died when coming to a stop and the 4th time it struggled to restart. I finally decided to pull into a parking lot and as I was backing into a parking space,...

While driving on a 55 mp road [XXX] the truck just stopped running. I had just turned from [XXX] onto [XXX] and had not gotten up to speed. I was only traveling at about 25 mph when the truck seized and stopped. No power to control vehicle. No power and no warning prior to no power. Only 18k miles on the truck and it died and wouldn't restart. It sat in the middle of the road and stayed in the middle of the road for an hour waiting on a tow.

Truck just made a year old and killed on me in the middle of road. They are saying I need a new engine and maybe transmission. Could not shift truck into neutral, which left me stranded on busy road. For unsafe and had me nervous. Trying to get GMC to buy me out of this vehicle. Had same problem with 6.2 liter prior to this truck. Engine and transmission was replaced. They promised if I bought new truck, I wouldn’t have the issues and here I am again. This is terrible.

1.During December 2024, noticed the wrap or called grill part at the back of the truck detached 2.On 5th February, got a warning :reduce acceleration with caution, when I pressed gas pedal, could not go faster than 35mph, the truck was shaking really hard. It has been in the dealership waiting for valve body until today 13th March, still no idea when it will be fixed

Catastrophic Engine Failure

Engine locked up while driving. I was able to get off the highway. Truck would not crank back up. When trying to start it screens would light up then go black. I had truck towed to nearest GM dealership. The GM dealership informed me that the engine was locked up.

The contact owns a 2024 GMC Sierra 1500. The contact stated that while driving on a main road at 65 MPH, the vehicle experienced a loss of automotive power. There was no warning light illuminated.

Driving on the highway vehicle installed out in the middle of the road lucky I had enough speed to rush to the median. I heard noise coming from the engine while I was coasting off the median on the median. Try to turn on the vehicle no luck.

Was driving approx 70 MPH when the truck lost power and put itself into neutral. Had to pull over on busy [XXX] in Missoula at 15deg F. Truck display said "restart vehicle". Once pulled over, truck put itself into PARK. Truck would not restart after multiple attempts. Was towed to dealer where they stated the engine may have seized.

Engine failed at 10,000 miles while driving down the road. No warnings, engine shut off while driving. I pulled over and contacted OnStar. They got me a tow truck to bring the truck back to the dealer the next day. I was told that I needed a new engine and they don’t know when they’re gonna get one in. It could be months. I had to pay for a Rent-A-Car out of my own pocket. The dealer would not cover the cost.

At 14,000 miles the engine seized. Car stopped on a busy highway almost causing a collision with other vehicles

I am beyond frustrated with my newly purchased 2024 GMC Sierra Elevation 1500 5.3l V8. Back in November I was notified to bring my vehicle back to the dealership for a complete engine replacement. Ever since this time I have had continuous problems with the vehicle. One day after receiving my truck back, I noticed that it was running rough and misfiring. When I opened the hood, I observed a bungy cord still attached to the engine. Several weeks after, the check engine light came on and took a week to get back due to sensor issues with engine. Today, after getting off work, I turned on my truck, but I am unable to shift out of park and I am stuck waiting on a tow truck. There has been nothing but issues with this truck since they replaced the engine. I am not sure if the mechanics at Garlyn...

6.2L V8 engine failure

Since owning my truck new, the vehicle has had numerous issues with loose exhaust and engine components. The truck has had loose catalytic converter bolts, heat shield and exhaust components causing severe vibration in the driveline, dash and floorboard. My son has the same truck 3.0 LZO other than his being a 2025, he has experienced the same issues.

6.2 ecotec GM engine failed, it is available for inspection at the dealership. The engine failed while driving with no shoulder to pull over. According to the dealership the main crankshaft bearings failed causing catastrophic failure. The dealership has confirmed and reported to GM on 1/24/25. There was no warning to the failure. I was driving approximately 40mph and lost complete power with no warning whatsoever.

was driving on the highway at 55mph and the engine just quit running and thankfully no one was near me and I was able to pull over on the side of the road. All the dash lights stayed on but the truck would not restart,code on dash board said "Conditions not correct for shift" Had it towed to the dealer and they put a new battery in it, but it broke down again on the way home same as before. Now they are telling me I need a brand new engine.

Truck with >15000 miles on it suddenly stops on highway (Dec 6, 2024). Engine won't start but all electrical components work, retractable steps, radio, bluetooth etc. When attempted to start, all electric went black and "push to start button again" came on display. Towed to dealer and after 3 days, advisor says it's not the battery but it might be something electrical. After six days I trade this truck in as they "don't" know what is wrong. After I trade they tell me that the truck needs a new engine but don't why. While taking my new 2025 truck in for a computer problem (500 miles) they tell me they found metal shavings in the oil. I find out two weeks later that there might be a problem with 877,710 6.2L engine with the same problem as mine. Sales says he doesn't know what problem is but he says he...

1st time Complete failure on my 2024 engine without warning. As I was traveling on the interstate. All of sudden, I lost all power. Mt truck started slowing down on its own. It was very difficult getting out of the way of on coming traffic. Dealership replaced values. 2 months later. Again on the Interstate engine complete failure again. Now take it to dealership. This time I heard a ticking noise. Right after the ticking noise. Engine stop working. Same situation. Trying to get out of the way of traffic. I was stranded over 3 hours.

On 01/24/2025, I was driving my GMC Sierra in the express toll lane at approximately 75 mph. The toll lane had two lanes and was enclosed by concrete barriers on both sides with no median or shoulder to pull over. Without warning, the engine suddenly shut off. There were no warning lights, no unusual noises—just complete engine failure. The power steering also stopped functioning, making it difficult to control the vehicle. I immediately shifted into neutral and focused on keeping the wheel steady to avoid triggering the wheel lock, which could have caused me to lose control and crash. I was forced to coast to a stop, barely managing to find a narrow sliver of space on the median of an on-ramp to the express lane. However, even then, my vehicle was still partially blocking the right lane of the express toll lane and partially in the on-ramp. There was...

I purchased this vehicle new in August of 2024. Approximately 2 months ago when the temperatures outside temperatures started falling below freezing, I would frequently get a message, "reduced acceleration, drive with care" pop-up on the center screen, and the check engine light would illuminate. This happens almost every time the outside air temperatures are below 28-30 degrees. Occasional the truck engine loses power and acceleration, but not always. This code pops-up regardless of the engine temperatures. It has been to the dealer where I bought it each time, and they state that GMC told them it is normal. They reset the computer, and the check engine light goes out until I run the truck in temperatures below 30 degrees. The dealer has been great with me, but dealer reports GMC will not cover their services under warranty as GMC reports this is normal. This condition happens unannounced and almost...

I was driving on the highway and my truck went black and engine stopped no power to truck. It was very scary. I pulled over and it was in Neutral and somehow got it into park. The car never would turn over. The truck is at midway motors with metal shavings in the engines. They say it locked up and needs replaced. GM is very difficult to work with and won’t give us any information. I’m scared of the truck.

I was driving my truck on Friday, [XXX], at approximately 50 m.p.h. The tires suddenly locked up and skidded momentarily and then released. Then a very loud clanging noise started in the engine. I lost power and coasted to the side of the road. Then the engine stalled. The truck was towed to Keeweenaw Chevy/GMC in Houghton, Michigan. I was later contacted by the Service Department and informed that the engine had indeed blown and a new engine would need to be installed. Engines are on LONG backorder. I was lucky I wasn't traveling 65 m.p.h or on snow covered roads, as this incident could have then resulted in a complete loss of control and hitting a logging truck head on.

Driving on hwy at 65 mph truck shut off without warning and display said shift to neutral and push start. Truck wouldn’t shift and nothing worked. Coasted to the shoulder where I sat for 5-6 hours waiting for a properly equipped tow truck. Motor was seized.

The motor seized up, while driving, no warning lights, just died, had towed to the dealership and was told the motor had seized up, it has now been at the dealership for 45 days, I am being told that there is not a new motor available to replace mine

While driving my truck it suddenly lost power. The truck had been operating normally with no prior issues before it shut off without warning. The truck was towed to a local dealer where they later told me the engine had seized up and needed to be replaced. The truck is a 2024 model that I had purchased new two months earlier. It only had 4,533 miles on it. I was driving at highway speeds and had to coast into a gas station parking lot. I was able to coast to safety, but losing power at highway speeds certainly increases the chance of having an accident.

November 15 I was driving home from work as the truck started jerking. The system was giving me an engine failure drive with caution warning. I pulled over and decided the turn off the truck and turn it back on. Once I turned it back on it was revving on its own. I decided to turn it off again and it stopped revving but the gears would not shift. You were physically able to switch them but as much as you pressed on the gas to reverse it would not. I had to have it towed to the dealership I purchased it at. It has been 3 months and the part that is needed is still on back order. I placed a compliant with GM and they opened a case but nothing has happened yet as far as getting an ETA on the part.

On December 25, 2024, my vehicle completely stalled in the middle of the highway while travelling at 65 mph. Fortunately there were no vehicles travelling in close proximity to me at the time as my speed rapidly decreased. The abrupt stall required me to pull over to the side of the road to attempt to restart. I was unable to restart the vehicle despite numerous attempts. Jump starting was also unsuccessful. I was left stranded 90 miles away from home in freezing temperatures during a snowstorm on Christmas night. My vehicle was towed to a dealership 140 miles from home as GM would not cover the cost of towing to the dealer closest to my home (68 miles away). After numerous phone calls with GM as well as the GM dealer, I was informed 9 days later that my entire engine (6.2L V8) would need replaced. I was also informed...

I was waiting in a parking lot to pick up the kids from school. In park, the truck loses power and almost completely shuts down. When it Reva back up there was a horrible hammering noise. I turn the truck off. Then I called the dealership and told them. I cranked it and recorded it for them and then shut it off. Then the tow truck couldn’t tow and it took two hours to get it loaded because of the features locking things down. It has been 29 days before the finally told me it needs a whole new engine. They still will not tell me why though.
