May 2026 STRUCTURE,UNKNOWN OR OTHER upper grille detachment while driving on the interstate at 70 mph at night ,hit the windshield. could not find it. Crash: No Fire: No Unknown
May 2026 STRUCTURE 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. Crash: No Fire: No Unknown
May 2026 ENGINE 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.

May 2026 ENGINE 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.

Apr 2026 ENGINE 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.

Apr 2026 WHEELS I purchased a 2024 GMC SIERRA 1500 Denali Crew Cab Diesel 3.0L After several times bringing the truck to the dealership I purchased from and conduct all service related work. They finally found a crack/whole in the sidewall that was not done by any road hazard to cause damage but looks like a manufacturer defect. This is now not only prominent on one tire but two of the tires. The area is on the covex area of the tire. BRIDGESTONE ALENZA A/S 02 Size 275/50/R22 This is a huge safety concern as a blowout at 65MPH could cause significant harm to not only people in my vehicle but to others. This is an advisement to get the right attention on this before something catastrophic or deadly. With plenty of tread on the tires (6/32), which equated to 50% life on the tire. The dealership is trying to make me pay for a manufacturer defect of $600+ for the two tires.

Apr 2026 ENGINE I was driving and lost engine power in the left lane of a freeway, cut across traffic and coasted to the shoulder. Had truck 6' off of road, though with semis and cars passing at 70mph, I left and waited in the ditch for the tow truck. The electronics worked, but the engine was dead and would not start. When the tow truck arrived, the wheels were locked up and they used rollers to haul the truck to the dealership. After the dealer inspected the truck, they sent a message saying they could not turn the engine over by hand. The engine had metal shavings in the oil filter and after removing a valve cover, found metal contamination circulated throughout the engine. The engine, radiator, oil cooler lone, and battery junction box all require replacement. This truck has a 6.2L L87 engine, and the dealer has had several other vehicles with the same blown engine failure. The truck was in for the recall on this issue about a month before the engine went out, they placed a pico scope in the engine to check the drive shaft, and then added a heavier oil. No warning lights came on until the engine died.

Apr 2026 ENGINE Engine Failure. I was driving down the highway pulling a trailer and the RPMs raced up and I instantly lost power. Had to try and get over to the right lane/shoulder after losing all power. Extremely scary situation going 75mph on a 3 lane highway in the left lane. Luckily I made it to a safe spot but once there, I could start the truck. It. Would sit a power cycle. Tow truck couldn’t get it into neutral so had to drag it up the flat bed. After being towed to dealer they confirmed the engine was shot and ordered a new one on March 9th. We are now over 30 days without my truck. This has not been inspected by anyone besides the dealership it was towed to and the dealership I bought the truck from and use for service. My truck was in the shop many times prior to this. Had to have the cam shaft replaced before the recall fix was published to dealerships. Once fixed my wife picked it up with my child and once they left the dealership it started vigorously shaking again and she brought it back to be told it was a fault plug and plug wire. Once our VIN came up for recall it passed the test and they put new oil in and sent me on my way. A couple weeks later it was acting strange again and I brought it back for them to again say it was a faulty plug/wire. About two weeks after this is when the engine locked up. Truck has 38,000 miles and doesn’t feel safe for our family. What can we do?!

Mar 2026 STRUCTURE The front upper grille broke off and detached at highway speeds. The grille impacted the hood, causing a scratch and dent and became a road hazard and has the potential to cause an accident. This is the same failure reported in NHTSA Campaign Number: 25V-060 that only covers 2022 model years. Research online indicates failures in 2022, 2023 and 2024 vehicles. GMC to date will not warranty or recall this gross safety violation.
