2024 GMC Sierra 1500 Safety Overview

Component: ENGINE

"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!"

Component: BACK OVER PREVENTION

"The contact owns a 2024 GMC Sierra 1500. While shifted in reverse, the back over prevention camera intermittently displayed a black screen accompanied by two failing camera symbols. During the most recent failure, the camera displayed a blank image, causing the vehicle to crash into the garage door, causing damage to the garage door. The failure was intermittent. No injuries were reported. A police report was not filed. Medical attention was not needed. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown."

Component: UNKNOWN OR OTHER

"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."

Component: TIRES

"The contact owns a 2024 GMC Sierra 1500 equipped with Maxxis Tires, Tire Line: Bravo HT-750, Tire Size: 255/80/R17, DOT Number: 120NK10015028. 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."

"The screen shakes. Goes black. Zooms in randomly without prompting. Started dialing up people from recent calls. While trying to get the navigation working. I started drifting into oncoming traffic. Fortunately was able to course correct and avoid collision. Buttons are most time not responsive to touch. It is distracting. The system has never fully worked as promised and is a distraction. And as a result a serious safety hazard."

"The vehicle received the official N252494001 recall oil remedy on 06/27/2025 at 15,438 miles (but suffered catastrophic engine failure and loss of propulsion at 33,661 miles on 05/30/2026)."

Component: ENGINE

"On XXX, while traveling at 75 mph on a major interstate highway, this 2024 GMC Sierra Crew Cab suffered a sudden and catastrophic internal engine seizure, resulting in an immediate and total loss of propulsion. This defect put the safety of all occupants and surrounding motorists at extreme risk, forcing the driver to navigate a completely unpowered, rapidly decelerating vehicle through high-speed traffic to reach the shoulder without the aid of engine power. There were absolutely no warning lamps, error messages, or mechanical symptoms prior to the failure; the engine locked up instantaneously without any advance warning. Following the incident, the vehicle was flatbed-towed to an authorized franchise dealership (Dossett GMC in [XXX]), where it remains un-repaired and is currently available for inspection by the manufacturer or federal investigators upon request. Critically, this vehicle was previously presented to a certified General Motors dealership at 34,766 miles for inspection and service compliance under Federal Safety Recall N252494001 (which covers engine component failure and subsequent loss of propulsion). The vehicle was cleared as passing the manufacturer's inspection protocol at that time. The total engine failure and seizure occurred less than 9,000 miles later at approximately 43,634 miles. The catastrophic field failure of this vehicle demonstrates that the manufacturer's current safety recall inspection and remedy are insufficient to identify or mitigate the defect, presenting an ongoing and severe risk to public highway safety.

Component: ENGINE

"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."

"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."

"The front upper grille deflector detached and hit my windshield and bounced off behind me during a drive at normal highway speeds. This created a random flying debris object that appears to have been a problem with the 2022 and later Sierra 1500 models; however, the recall only appears to address the 2022 model. It also appears quite common for the 2024 year model as well. Vehicle has never been in an accident so nothing beyond typical use would have caused damaged to the connections. The plastic connectors appeared to have failed."

"Traveling Northbound in the left lane on [XXX] approximately 1 mile prior to the [XXX] exit. I increased my speed to move to the right lane and exit. After moving the the right lane and signaling to exit the highway a notification appeared on the gauge cluster stating to shift to neutral and restart the engine. After coming to a complete stop at the stop light I attempted to restart and nothing happened. I contacted OnStar for roadside assistance to get my truck and trailer towed and was informed they do not cover towing of the trailer. I accepted the tow of the truck and contacted the towing company who charged me $300 to tow my trailer 15 miles home. This happened late morning on Saturday and by Monday evening I was informed my engine seized and GM will be covering a replacement under warranty. My truck is less than two years old with 23K miles. The 6.2L engine was inspected a couple months earlier for the engine recall and was deemed ok. Clearly the inspection process is not very robust. I was told I could be without my truck for 1wk, 2wks, a month, but they are not sure since I’m 4th in line for a new engine and the truck first in line has already been there a month. I was also told GM is showing inventory in Michigan but the engines are not shipping. I’m currently waiting on a loaner vehicle but was told I cannot tow with the loaner vehicle which throws a wrench in my plans.

"October 24, 2025 I had taken in my vehicle for recall 25V274 Loss of motor power. Mine was deemed unaffected and given the oil change they were doing as part of that. Today it died while I was pulling a trailer with a RZR on it. I had drove about 90 miles with a stop midway when I did have the engine turned off. Then it just quit. My vehicle only has 13k miles on it. Not sure if police report was filed but they were called and there directing traffic because it stopped in a busy intersection. I had to be towed, and pay a separate fee to have the trailer towed. At 1000 miles on the truck it had to be taken in for an infotainment screen replacement."

"GM 6.2L L87 was recalled. I took the truck in at 32,000 miles. GM dealer perfromed a Pico Test, motor failed. Motor replaced with "NEW" crate motor. I was without a truck or loaner for 3 weeks. Dealer called me when new motor was almost complete. First they said it would be a couple more days because they started the "NEW" motor and it had no oil pressure. They contacted GM Tec and they tested it again, it tested with too-high of oil pressure. GM then instructed them to replace the oil pump on the "NEW" Motor. I got the truck back a week later after being in the shop 3 weeks. I drove a total of 1,200 miles, 400 miles we're highway in one long trip. The balance was local. I went to start the truck one morning after it sat all weekend and the "NEW" motor was knocking like an old diesel. I video'ed it and sent to my service advisior, I was advised to bring it back again. Vehicle has been at dealer now 9 days, dealer took oil sample from "NEW" motor, it was found to have metallic matter in the oil. They contacted GM Tec again, it took GM Tec 3 days to respond, Last Friday GM Tec said pull the oil pan and take pictures. As of the typing of this email I have no loaner because there's a wait list for loaners, GM will only reimburse me $25/day for a rental and a truck rental is $105/day which I refuse to pay for GM's defects out of my pocket."
