2024 GMC Sierra 1500 complaints

Back up camera is almost useless in very dark situations. Back up lights on vehicle wash out the view and all you can see are the red marker lines. Needs either brighter back up lights or a better camera definition. You cannot see a children's bike or other things while trying to back up.

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 Shelton GMC in Temple, Texas, are qualified to replace engines. This is a brand new truck and I should not be having these issues. My fear is that these problems are going to continue because they either did not properly install the new engine or there are still defects.

First time it happened was on November 28th 2024 around 8pm, turned de engine on, selected the reverse gear and stepped on the gas, the reverse gear was selected but the gear didn't worked at all. I almost hit a car that was passing on the street. I out the gear on drive and got the message "reduced acceleration". I believe that is a known issue by GM's 10 speed gearbox. The car is at the dealership and they informed me by e-mail that the part transmission valve body is in a "do not sell list". I have concerns about safety because losing power on a 70miles per hour road can be dangerous and not being able to reverse is also very dangerous. There are tons of posts about it in Facebook.

I have experienced several occurrences of unintended acceleration while operating the vehicle at low speed. Two recent examples; 1) the truck accelerated rapidly while I was driving into my garage, and 2) the truck accelerated suddenly when pulling forward out of a parking spot in the morning shortly after starting the vehicle. In all cases, a hard application of the brake pedal slowed the vehicle. I considered whether this was operator error, possibly engaging cruise control inadvertently while turning the steering wheel, but the incident this morning does not support that potential cause. I have not spoken to the dealer about this issue.

6.2L V8 engine failure

Since my purchase of the vehicle Dec 2023, the tailgate opens on its own. Usually follows hitting a bump such as the rain gutter entering a store parking area. I have also had it occur while driving down the road. Have been told multiple times by my service personnel they have had same complaints from other Sierra 1500 but have no fix for the problem. They have offered to deactivate the electronic tailgate system but this is unacceptable to me. There is a recall for 2500 models with same issue but not for 1500’s. This makes little sense.

The contact owns a 2024 GMC Sierra 1500. The contact stated while driving 74 MPH, the vehicle inadvertently lost motive power, after which the vehicle was unable to accelerate above 25 MPH. The contact was able to pull over to the shoulder of the roadway and turned off the vehicle. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The check engine warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the shift solenoid valve and that the serial data gateway module needed to be reprogrammed. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 24,000.

7500 miles and transmission valve body failed. Parts are on back order with no eta.

While driving a new 2024 GMC Sierra SLT (13,000), I received a prompt to SERVICE SAFETY RESTRAINT SYSTEM. My airbag lamp also illuminated and is now on. Upon researching this issue, it refers to potential failure of seatbelts and/or airbags. I have an appointment tomorrow at the dealership to have them diagnose the issue.

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.

The transmission would just give out. It also wouldn’t reverse. The cause was a faulty body valve that gm can’t produce fast enough.

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.

Only owned my 2024 gmc sierra 1500 for 5 months close to 10,000 miles on odometer. Transmission valvebody failure. Gm and dealership says no ETA for a replacement part. Im hearing from other customers with same issue part will take 5-6 months for dealership to receive part. I have a brand new truck that im making truck payments on just siting at the dealership waiting for a transmission valvebody. This is unacceptable! There are many many GM customers dealing with this same issue.

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 may be stuck with the truck for 30 days or more so I should trade.

The contact’s son owns a 2024 GMC Sierra 1500. The contact stated that after coming to a complete stop, the “Service Traction Control” message was displayed on the instrument panel. The contact turned off the vehicle and waited for a while before attempting to restart the vehicle; however, the vehicle failed to restart. The contact stated that the “Service Steering Column” message was then displayed on the instrument panel. A dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 28,140.

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 nowhere safe to go, no way to restart the truck, and I couldn’t exit the vehicle due to high-speed traffic surrounding me on both sides. I sat in my disabled truck, utterly exposed, fearing for my life as cars sped past me at 70+ mph. I kept imagining the worst—that an inattentive driver would slam into me, causing a catastrophic accident. Thankfully, after several harrowing minutes, a police officer arrived to block traffic behind me, and another cruiser blocked the entrance to the express lane. Only then did I feel a shred of relief. This was one of the most terrifying experiences I’ve ever endured, and I wouldn’t wish it on a

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 all the time in cold temperatures. It has happened at least 12 times. The performance can be a safety issue when this condition comes about, and you're driving in traffic. I opened a case with GMC on Thursday, January 16, 2025. It is case number [XXX]. I spoke with Graham, the customer service representative who reported that this issue will be escalated to the regional CE Manager because of the frequency that this is happening. Graham reported to me that this CE Manager will be in touch within 2 business days which would be Monday, January 20, 2025. I received a call mid-day on

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 that there are two vehicles ahead of mine that require replacement of their engines and that the engines are back-ordered. They have been unable to provide an estimated timeframe on when my vehicle will be returned to me in working condition, stating it "could be months." When I was informed of the need for an engine replacement, I placed a request for a manufacturer repurchase which was ultimately denied the following week. The agent responsible for managing my case informed me that "GMC requires two to three major failures" before they will consider a repurchase approval. The dealership was not able to provide me a loaner vehicle and I was informed that GM onl

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.

Engine started making noises. I had it towed to dealership to get it diagnosed. Dealership called me next morning to get information on what vehicle was doing. I called dealership that same evening and they informed me that the engine locked up on the tech diagnosing the issue, and I was going to need a new engine.

Tailgate comes open without wanting too. Few times I've come to find the truck with the tailgate open, has occurred twice while driving. There is a recall for the same issue with the 2500 and 3500 series GMC Sierra. My truck is a 1500 series GMC. Surely same issue and faulty tailgate lock as the 2500 and 3500 trucks.

29K and I have metal shavings in the oil/lifter tick failure. T

Since brand new, the engine makes a significantly loud chirping sound at two occasions. First is every time the fuel saving auto start kicks in to start acceleration. The other is any time you come to a stop from above 25-35 MPH. At around 16 MPH, there is a loud chirping as you decelerate. This appears to be a timing malfunction and is affecting fuel economy. The vehicle has 8,800 miles on it, and it is getting worse. It has been looked at 4 times and has not been identified. I know there was a GM bulletin from 2022 about this 6.2L V8 Engine, but they state it is "normal". I have never heard a normal sound of this kind from an engine. And certainly not on a $75K vehicle. Please investigate and make them correct the issue or replace the engines. people work too hard to afford nice vehicles, and should not have to deal with this issue.

My truck was put on an engine oil consumption plan at ~14,000 milee. Then a month later the engine complete seized while i was driving at 60 mph in the middle of southeast Missouri. The dashboard started flashing with a warning saying that I needed to press the start button. The vehicle came to a stop and i was unable to get it to turn over. I currently have a warranty claim with GM amd the vehicleis at Laura GMC in Collinsvill, IL awaiting a replacement engine. I have no confidence in GMs ability to fully resolve the issue. My life has been completely disrupted as a result of their lack of quality controls.

See attached document for complaint.

Intermittent problems with various systems freezing up or not working: Windshield wipers freezing for several seconds mid-wipe. Nearly caused accident. Heads up display not retaining settings Seat controls (bladders that inflate deflate) intermittently working/infotainment screen freeze (where seat control is displayed). Lane departure warning inconsistently working (beeping) Radio quits playing for several seconds and screen goes dark Blinker stops blinking and then re-starts 6.2L engine slow/rough idle continuously hunting for stable speed (This is the only problem that is NOT intermittent). At times almost dies. A/C unit stuck on "hot" delivering 92 degree air when outside 72 degrees. Temp set at Low. (No A/C just trying to get fresh outside air in). Vehicle was under recall and control modules "reflashed" before purchased (new). Dealer reflashed which did not solve problems. Dealer cannot duplicate (but they only spend a little time looking at the issue). Has been in shop off/on for about 2 weeks attempting to resolve. Issues on occasion still occuring since Mid October 2024 purchase.

Engine bearing failure, complete loss of power while driving and turning left into oncoming traffic. Bearing failure confirmed by GM Dealer, brass shavings in oil pan.

On 12-26-24 the transmission on my vehicle failed suddenly going down the highway. Driving down the road a jerking motion and then all of a sudden the vehicle would not shift gears. Luckily the road wasn’t crowed because all of a sudden the vehicle slowed and would not accelerate. If someone had been following me there was no break light indicating I was slowing down. When I returned home I discovered I didn’t have reverse either. If I was in a place I needed to back up I couldn’t have. I took the vehicle into the dealer the same day and they diagnosed the problem was in the transmission. They ordered the part but it isn’t available and don’t know when it would be available. This leads me to think there must be many other transmissions with the same problem as mine. In my case there was no accident but if it had been on a congested highway there could have been.

On December 26th 2024, I was travelling 5 mph or less while pulling into a parking space at a restaurant. As I let the steering wheel return to center, my hand hit the Resume button on the left side of the steering wheel and the vehicle immediately began to accelerate. I was able to step on the brake to prevent the vehicle from hitting the wall of the restaurant. The next day on December 27th, 2024, i was able to duplicate the problem. I had set the cruise at 55 mph before I came to a stop at a traffic light. I released the brake and pressed the Resume button and the vehicle immediately accelerated from a dead stop. I've been an automotive mechanic for over 30 years and I've never seen this happen before. It's my understanding that vehicles wouldn't engage cruise control unless the speed was over 35 mph.

Failed transmission; needs valve body replacement but part is on national back order. Vehicle has been at dealership since 11/12/24. Almost 2 months and no eta when part will be in. Dealership did offer loaner after first 3 weeks. Vehicle is available for inspection, no safety issues as the problem occurred in driveway at home. If the problem had happened on the highway though, there would definitely have been some safety concerns. No prior warnings or symptoms. The problem has been confirmed by the dealer and was approved as warranty work. A recall should be issued.

On December 13th 2024, I was unable to drive my truck in reverse. I put the truck in neutral and pushed it out of its parking spot. I was able to drive the truck to the GMC dealership for diagnosis. On December 19th, I received a call from the dealership and I was told the transmission valve body was bad. I called on January 2nd 2025 for an update on the repair and was told the valve body was on backorder and they had no ETA on the Part.

Tailgate opened unexpectedly while I was pulling a trailer. Damaged tailgate.

On 2 occasions now my tailgate has opened on its own. The first incident happened sometime after I got home from work for the night, when I went to leave in the AM my tailgate was resting on the garage door and had been scratched. The second time it happened I didn’t notice it while driving but when I went to close the garage door I looked back and saw the gate was open and partially sticking out of the garage. Nothing happened this time to put anyone at risk however there is damage to the truck and if it happened while hauling something could have come out and hurt someone or damage property. I have not brought it to a service center yet. No warning

As I was driving on the highway the upper top moulding from the grill came off causing scratches to the hood. This is dangerous if it flies off into the windshield. This has been an issue for GMC.

Truck thinks I’m about to run into something and slams on its brakes. Last time it sent my sister to the hospital to get 6 staples in her head. Digital cluster goes on and off as well as the infotainment center. Transmission bangs and shifts horribly. 900 miles on the truck with a check engine light and transmission warning.

The reverse or backup lights do not properly illuminate, as the angle does not allow for viewing dangers behind at night. The lights are angled to aim way too high, and the lights are aealed. No way to adjuat. An adult standing just three to five feet behind truck, the lights illuminate at chest level, meaning a small child could not be seen at all, even with the rear view camera. Speaking of the camera, it not longer displays low light situations. People are going to be injured or killed because of these lights, or lack thereof of. On researching, this is a known defect since GMC went to LED tailings in the 2024 1500. This problem was not in my 2024 3500 as they use different lights. This is a dangerous situation.

See attached document for complaint.

Power sliding window leaking water. Available for inspection upon request. Leaking water can lead to mold posing in the vehicle leading to a health concern. Problem was inspected and verified by dealer and initial service bulletin repair was made to apply vehicle sealant to the top of the window. Window still leaked after the initial repair. Dealer planning to replace the entire rear window. This appears to be an issue with multiple years of GMC and Chevrolet trucks with sliding rear windows. No warning lamps associated.

The contact owned a 2024 GMC Sierra 1500. The contact stated while his wife was driving at 50-55 MPH, the front passenger side tire detached from the vehicle, and the front passenger side was damaged. The air bags did not deploy. A police report was filed. His wife sustained injuries to the neck and shoulder which required medical attention. The vehicle was not diagnosed or repaired. The vehicle was towed from the scene and deemed a total loss by the insurance company. The contact stated that the ball joint, hub bearing, and 4x4 drive shaft were damaged. The manufacturer was not notified of the failure. The failure mileage was unknown.

The contact owns a 2024 GMC Sierra 1500. The contact stated while driving at an undisclosed speed, the vehicle lost motive power with the message "Engine Power Reduced" and the vehicle was unable to accelerate above 5 MPH. The vehicle returned to normal functionality, but the failure became a regular occurrence. The check engine warning light was illuminated. The vehicle was towed to the dealer, who was unable to duplicate the failure or provide a diagnosis. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was approximately 9,000.

Illumination for the rear view camera is insufficient, making the camera useless for rear visibility in dark conditions.
