2024 GMC Sierra 1500 Owner Complaints

On [XXX] I was driving my 2024 GMC Sierra 1500 Vin # [XXX] on a major highway in Houston when without warning the engine shut off, stranding me in the middle of busy traffic. I was able to get to the shoulder and restart the truck, but no warning lights came on so I continued on my drive when approximately 20 minutes later, while still on a busy freeway, the engine shut off again. I was able to restart the truck and within another 15 minutes the check engine light appeared, the engine lost power and started making a loud rattling noise. Roughly 2 minutes later, as I was attempting to pull over to the shoulder and safety, the truck shut off and would not restart. This was the 3rd time for it to stall out on a busy freeway which was very dangerous for myself and the other drivers. I contacted the local Chevy dealership and they sent a tow truck out to tow the truck back to their dealership service center. I was later contacted by a service advisor that said they found a code P0016. He informed me that the engine would need to be replaced. As of today 8/11/26, they are still waiting on backordered parts to arrive before they can even start on any repairs.

Was traveling home and started losing power going up a hill on XXX. The truck was surging, the check engine light came on and an audible warning of no (low?) oil pressure. The truck shut off on a busy interstate highway and barely got onto the shoulder. The tow truck driver had to lay on the ground with part of his body in the lane of travel to place "skids" under the rear tires because there is no way to place this vehicle in neutral for a tow without a special GM tool. When I contacted Harry Robinson GMC service center in [XXX], they told me that it was no longer a safety recall because the truck had passed diagnostics and new, high viscosity oil was put in the truck XXX. The GMC app says code P0016 which is the dreaded 6.2L camshaft to crankshaft alignment that accompanies engine component failure.

Ever since I bought this truck new, I noticed a lot of metal shavings and debris in the oil filter every single time I changed the oil. I took it to the dealership multiple times to have this looked into before the engine recall came out. The dealership took pictures of the metal and sent them to a General Motors engineer, but the engineer just told them it was "normal." Later on, the truck went in for the official recall inspection, passed the PICO test, and nothing was fixed. Then on August 4, 2026, I was driving on a crowded expressway right through a construction zone with absolutely no shoulder to pull over on. Out of nowhere, the truck started hesitating badly, lost power, and the engine started making a really loud knocking noise. It barely ran, and it was incredibly dangerous because there was nowhere to go and traffic was heavy. Luckily, I was able to limp the truck along just far enough to clear the construction zone and pull over safely. the truck was towed to the dealer were they confirmed the engine was blown, and needs replaced.

While driving on XXX I received a message on the dash: service transmission, will not be able to shift soon. I went to the nearest GMC service center, located in [XXX]. Their diagnostics indicated that the Gear Shift Control Module needed to be replaced with new PN 86421783. That part was not available until XXX, but old PN 86274946 was available at a few dealersships, and it acould possibly be ordered and arrive sooner than XXX. I was told that driving the truck would be okay, but the part should be replaced as soon as possible. I live over an hour's drive from [XXX], and with the assurance that driving the GMC was okay, I chose to have the part shipped to and replaced at the dealership in [XXX], the nearest one to [XXX]. I drove back to [XXX], stopping at the Waldoboro dealership to make an appointment for their inspection of my truck, their troubleshooting the problem, and ordering the necessary parts to repair the transmission. When the part number went into their ordering system, the dealership was advised that no parts were available and no availability date was known. I contacted GMC Customer Assistance to express my concern and request assistance in locating the parts, but she was also unable to locate the parts or speed their availability. Again, on the assurance that the truck was okay to drive, on XXX I drove to my storage units near [XXX], and when I tried to leave and shifted into reverse the truck would not move. AAA towed me to the dealership in Waldoboro, and the replacement parts search began. Finally, on 7/28/26 I was advised that the part was at the dealership, and on XXX I picked up my repaired GMC truck.

The engine (6.2L V8) in my 2024 GMC Sierra 1500 AT4 failed at approximately 40,750 miles. I began hearing a ticking noise coming from the engine, and the dealership subsequently diagnosed the cause as damaged bearings that in turn damaged the crankshaft, requiring a full engine replacement. Notably, this vehicle was not included in the related recall covering this engine defect, despite exhibiting the same failure. The original failed engine may be available for inspection upon request but I would need to confirm with the dealership whether it was retained or already returned to GM under warranty. This defect creates a serious safety risk because a damaged crankshaft and bearings can cause the engine to lose power or shut off without warning while driving. An unexpected loss of engine power at highway speed or in traffic could result in loss of vehicle control, reduced ability to accelerate out of a hazard, and increased risk of a collision to myself and to other drivers on the road. The failure gave no advance warning, so there was no opportunity to pull over safely before the issue became apparent. The fact that this failure occurred outside the scope of the existing recall suggests other vehicles with the same defect may be similarly at risk without notice. The dealership diagnosed damaged bearings and a damaged crankshaft as the cause of the ticking noise and performed a full engine replacement under warranty, confirming the failure. The dealership diagnosed the failure and performed the repair; I do not have direct confirmation of whether GM's engineering or warranty division conducted a separate inspection of the failed components beyond the dealer-level diagnosis. No warning lights or messages appeared on the dashboard at any point. The only symptom prior to failure was a ticking sound from the engine which I noticed shortly before the engine required replacement. I was not provided any electronic warning that would have alerted me.

I was driving on the highway when the vehicle started to make clinking noises. The vehicle started to lose power as I accelerated it would feel like something was pulling me in the opposite direction and the knocking noise would get louder. Ultimately, I had the vehicle towed to a dealership. This vehicle passed the L87 recall not too long ago, and the vehicle is barely used.

2024 GMC Sierra 1500 6.2 v8 had a full engine seizure while driving on the freeway. All prior recall actions had already been met (scoped and upgraded oil), within 60 days of dealership review the engine stopped working. Recall 25V-274 L87 Engine Loss of Propulsion. After a 5 hour event on the side of the road AAA towed the vehicle to the dealership where I was told it would be many months before this is returned. It took many weeks for GM to just review and approve any next service (engine needs). At this point I'm told there are 181 people also in line for an engine and they can't see where I might be in that line. So we wait.

On XXX I started on a 3 hour trip with my daughter in the truck. My vehicle lost power and started knocking in the engine compartment. We were going over a very big Bridge([XXX]) from [XXX] to [XXX]. I had to coast off the highway and made it to a park. Truck would not restart and would not go into neutral. Waited 5 hours for AAA and was drug onto the flat bed truck because it would not go into neutral. It was then towed to the dealership(Union Park GMC) in [XXX], where they had to drag it off the flat bed truck. Truck was evaluated and determined by the technicians that it needed a new engine(6.2 L V8). Engine was tested and passed in October 2025. Still waiting on a new engine to be installed(today is XXX). GMC knows there are issues with these engines failing and continue to sell to the consumer. I am currently paying for a truck that I am not able to drive.

I was driving at normal highway speed. I exited the highway and started to deceleration for an upcoming traffic light. The engine started making a lot of noise. The 6.2L engine has 31k miles on it. Oil changes have been completed at the dealership where I purchased the sierra Denali. I called the dealership and the service writer could hear the engine noise. He asked if I could get it to the dealership which was about 15 miles away. I tried but the truck stopped about 7 miles from the dealership. They told me to call the onstar service and get a tow. The dealership said it will take about six weeks to get a new engine. In the meantime I'm making payments on an eighty thousand dollar vehicle I can't use. Someone needs to hold GM accountable for the lack of urgency in getting this problem fixed!

The vehicle suffers from a persistent transmission defect including shuttering bucking slipping torque converter failure valve body failure twice metal debris improper down shifting chirping noises and related liability and safety issues. The vehicle has undergone multiple unsuccessful repair attempts at authorise GM dealerships. These repairs include torque converter replacement valve body replacement twice solenoid replacement fluid services software updates. The transmission problems have persisted despite these efforts and the vehicle has been out of service for more than 22 business days including a breakdown driving to Florida. I have filed a claim through GM but it seems like it just keeps getting pushed further and further away this is a serious safety issue as I fear for those driving around me and myself that I may cause an accident with the bucking slipping and failure to operate properly on the road.

This vehicle became subject to a manufacturer safety recall requiring complete engine replacement. The engine failure has been confirmed by an authorized GMC dealer, and the vehicle has remained out of service for more than one month while awaiting the recall remedy. The dealer has advised that the repair has been escalated through GM's SPAC (Service Parts Assistance Center) process because a replacement engine is not available. General Motors has also confirmed there is currently no estimated delivery date or estimated completion date for the repair. As a result, the recall remedy is effectively unavailable, and the vehicle remains unusable for an indefinite period. Although a temporary loaner vehicle has been provided, it is not functionally comparable to the recalled vehicle and does not provide the towing capability and utility required for its intended use. The vehicle was inspected by an authorized GMC dealer, who confirmed that engine replacement under the recall is required. The vehicle remains available for inspection. My concern is not only the original safety defect but also the inability to obtain the recall remedy within a reasonable timeframe. There has been no estimate of when replacement engines will become available, leaving the vehicle out of service indefinitely. I am submitting this complaint to document the delay in completing the safety recall and to request that NHTSA review whether the recall remedy is being provided in a timely and effective manner.

My 2024 GMC Sierra Denali Ultimate 1500 experienced a catastrophic powertrain failure that created a serious safety hazard. On XXX, while driving at highway speeds, the truck unexpectedly shifted into neutral, causing an immediate loss of propulsion. During this event, the electrical system was also affected. The battery power dropped, power steering assistance was lost, and due to the electronic push-button start system, the vehicle could not be restarted while in this condition. This placed me and surrounding motorists at significant risk of a crash. I initially brought the vehicle to Point GMC, where I was advised no issue was found. After the problem continued, I returned on XXX and a dealership technician rode with me. During the test drive on [XXX], the truck again shifted into neutral, confirming the defect. The vehicle was then towed to the dealership, where diagnostics revealed DTC P0016. I was informed the engine had seized and required a complete engine replacement. The engine was replaced by an authorized GMC dealership in New Jersey. After only about 2,000 miles, the check engine light returned and the vehicle began experiencing additional electrical issues. This is a Denali Ultimate, the highest trim level, with advanced electronic systems, making these recurring failures especially concerning. To date, the vehicle has been inspected by three authorized GMC dealerships, and I have opened multiple cases with GMC Corporate. Despite repeated repair attempts, the manufacturer has not provided a permanent resolution. I continue to experience recurring engine and electrical issues and no longer have confidence in the safety or reliability of this vehicle. Given the repeated failures, loss of propulsion, loss of steering assistance, inability to restart the vehicle, and lack of resolution after multiple dealership visits and an engine replacement, I believe this matter warrants investigation by NHTSA.

The contact stated that after the front driver 's-side tire became flat, the contact discovered that the spare tire originally equipped on the vehicle failed to fit the front wheels but did fit the rear wheels. The vehicle was towed to the dealer, who determined that the spare tire failed to fit the front driver's side wheel due to a factory-installed brake modification, causing the spare to not fit over the front brakes. The dealer replaced the front driver's side tire. The manufacturer was made aware of the failure. The tire failure mileage was unknown. The vehicle failure mileage was 14,000.

Upon driving on the highway, I was doing about 73mph, something back flew up and smacked the windshield then the car behind me ran over that piece. After stopping and looking I realized the top trim to the grill flew off. There is no recall for this even though this is a safety concern. If I was near a sidewalk to a motorcycle behind me this could have injured someone severely. Upon research I found that there is a recall for the 2022 model for the same problem (Recall N242490120), this needs to be extended tot he 2024 model as I have another truck (same year and model) that is showing signs of the same issue. This is a huge safety concern.

This vehicles top portion of grill trim is starting to come loose, as this is a safety concern while on the highway, I had another vehicle that the trim flew off completely, (same year and model) while i was on the highway. This could hit another vehicle if this happens, or god forbid a person who happens to be on a sidewalk. I looked into this and found that there is a recall for the same issue on 2022 models that has not been extended to the 2024 model (Recall N242490120). This recall should be extended to the 2024 models as this is a huge safety concern.

Issue is with the transmission as it harshly shifts into a low gear when on an incline. This causes me to lock up my breaks as it feels like the truck was rear ended by another vehicle. I’m concerned that this is going to cause an accident. This problem has not been reproduced by the dealer. I’ve taken it to the dealership several times. No warning lamps or messages.
