First started around 4 to 6000 miles, felt a shuttering between 50 and 65 mph. Shattering lasted from 10 to maybe 30 seconds let off the fuel and reapplied still there on one or two occasions. RPMs were approximately 2000 RPM shattering stopped in our PMs went down to 1500. This is occurred many times taken to a dealership always get same result, no problem found. Problem always occurs just after a transmission shift which I can tell by RPM. When I apply gas shuttering sometimes increases not always. Also noticed that sometimes shifting on a flat surface 65 miles an hour engine will speed up to almost 2000 RPM and when it goes to shift back, I get a clunk or sometimes a shutter normal cruising is about 1500 RPM at 65 mile an hour. I didn’t notice towing an empty trailer about 2600 pounds shattering seemed worse. With no Trailer I sometimes get erratic shifting where RPM goes 1500 to 2000 to 2500 and then back down again then back up again then it can shift all the way back to 1500 RPM still maintaining 65 mph. Also another problem may be connected to transmission, but I have pulled out into traffic pushed on the pedal and it feels like the truck has no power push on the pedal a little bit more still no power and all of a sudden it’s like everything kicks in RPMs, increase rapidly and truck accelerates extremely fast, throwing things off the dash moving things on the floorboard. Sometimes I see that a downshift occurs and RPMs increase other times I see RPM staying right at the 2000 mark and it still occurs almost got rear ended a couple of times. Check engine light has been on one dealership said they pulled over 40 codes. Still they all claim can’t duplicate problem. Yes I agree it is random but with me watching telemeter and County shift points biggest problem area is fourth gear fifth gear and sixth gear.

On or about March 14, 2026 vehicle in question stopped working, losing all power and gave a message that the vehicle was over heating and to turn off immediately. A large amount of steam emitted through the coolant reservoir that was a mixture of oil and coolant. Vehicle was towed to a manufacturer service location. The oil/coolant system ruptured damaging the radiator, thermostat, hoses and related parts. Vehicle with low mileage/hours was consuming engine oil at what one would consider a greater rate. ( 1 quart every other day). Our organization is aware that the diesel model of this truck had a recall for a oil/cooling system issue and we believe the same liability may lay with the gas version. Mileage was approximately 13,000 at time of breakdown.

My 2024 Chevrolet Silverado 2500HD Bison ZR2 (VIN [XXX] ) suddenly lost all power steering, acceleration, and propulsion while driving my children to school at approximately 8:00 AM on March 16, 2026. The truck came to a complete stop with no warning lights or prior indication. This matches the exact ‘critical issue with the engine and transmission system’ alert I received from OnStar Advanced Diagnostics the same morning. Steering was completely unresponsive and I had no acceleration. My children were passengers — this was extremely dangerous. I have not driven the vehicle since and have requested towing to the dealer. Please investigate under any open probes into 2024 Silverado HD power-loss and steering failures.

The check engine light goes on continously and it goes to limp mode. The truck cannot be driven daily and most of the time is in the dealer fixing the updates or computer. It is not an equipment problem but a computer problem.

My 2024 Chevrolet 2500HD Duramax experienced a forced emissions derate event with a speed-limited countdown. The vehicle suddenly lost normal operating capability and became unsafe and undrivable. The truck was disabled in Enid, Oklahoma and had to be recovered and transported to a dealership. Prior to failure, the vehicle showed abnormal DEF/emissions behavior. The failure involves the SCR/DEF emissions system. I later confirmed this vehicle has a completed Product Emissions Recall for SCR Fault Detection. Despite that recall, the emissions system failed and triggered a derate and loss-of-mobility event. The truck is currently at Classic Chevrolet in Owasso, OK for diagnosis.

With 19,000 miles on my Silverado 2500 HD I was traveling down a hill towards a stop sign at a T intersection. About 100 yeads from the stop sign I had many flashing errors on the dash, very little brake and very little steering. The engine just shot off. Fortunately I was able to stop the vehicle right at the stop sign while traffic from right and left had no stop sign. The truck would not start after. It did have electrical power. I tow was needed. The next day the Chevy dealer did find a bulletin for a wire in the engine compartment chaffed. Symptoms were the same as what I experienced. Repair was made. Bulletin #24-NA-124. There is no doubt a bulletin should be issued but I believe this is a real safety issue with the engine just randomly shutting off leaving no power to brakes and steering. Had this happened while I was towing our camper I would not have stopped and t boned another vehicle causing damage and no doubt injury to others and myself. If traveling on an interstate at 70 MPH this could have been even worst. This is a known problem and should be a recall and not just a bulletin. Thanks.

My business work truck started not shifting properly. I dropped it off at Mirak Chevrolet in Arlington, MA on 4/29/25 and they diagnosed the vehicle needing a valve body part # 24065357. GM/Chevrolet has been unable to source this part and was unable to provide an eta. I immediately contacted GM and my case # is [XXX]. Then it was approved and escalated for a new transmission and same issue unable to source part and no eta. This is my business vehicle that has not been operable since [XXX] due to a manufacturer issue. No fault on my end. This is a brand new vehicle that should not have these type of issues. I have lost revenue, income, jobs, and I don't have a replacement vehicle. I have a loan on this vehicle that I am making payments towards but there is no end in sight. It has been a month with daily calls to GM for an update or for someone to call me back and nothing. I need my work truck back. This has caused extreme financial stress. I need help.

The truck went to the dealer for recalls on March 21, 2025. The Truck is still within the bumper-to-bumper warranty. Recalls consisted of tailgate fix, TCM & ECM updates. The truck was returned to me approximately a week later. I noticed a significant loss of power. I took the truck back to the dealer and told them about the issue. They had it another 2 days and returned it to me, saying there was nothing wrong. Approximately a week later, I was driving down the road and the check engine light appeared on the gauge cluster. I immediately drove the truck to the dealer, and the DTCs were emissions-related. The service advisor, Jeff, told me to keep driving the truck, and it might go away. I drove the truck home, 20 mins away from the dealer, and as I pulled into my driveway, a message on the gauge cluster said, "Add engine oil." I notified the Dealer of the issue immediately. The next morning, I added a gallon of oil, and there were still no signs of oil on the dipstick. At that time, I noticed there was no coolant in the reservoir, but engine oil residue, and a collapsed upper radiator hose. The truck was towed to the dealer later that day. After inspection, the dealer said the oil cooler had failed. They sent me the service bulletin, but that bulletin only says, "oil and coolant mix," nothing about the disappearance of the fluid, and no explanation of the emissions codes. The dealer and GM's corporate office are refusing the share the diagnostic data on how they have concluded that the oil cooler has failed. Their solution is to replace the oil cooler and see what happens. This truck has 1000 miles left on the warranty, and the parts/procedures expire at the end of the bumper-to-bumper warranty. Recap: GM will not share diagnostic data, and they are refusing to extend coverage, yet their remedy is to experiment with my $70,000 truck, and the moment this truck is out of warranty, they are going to wash their hands of it. That is not acceptable.

On July 1st, 2023, I purchased a 2024 Chevrolet Silverado 2500 from Orielly Chevrolet in Tucson, Arizona. On July 2nd, 2023, an error message popped up on the dash, “Park Assist Blocked See Owner’s Manual”. It continued to happen on and off til this very day. The dealership "attempted" to fix the issue, but it obviously hasn't been resolved. Due to equipment being faulty, the chances of an accident whilst back up are significantly increased. At one point on this ordeal, the truck was in the shop for 61 days. It had been in my possession for 18 days. I am currently in the process of a buyback for the vehicle. I had to hire a lemon law attorney. A supervisor from GM advised that GM is refusing a buy back for the vehicle. The vehicle also displayed an error, "key not found" while I was driving at 50mph. A bit unsettling. That error showed up twice on the dash. The dealership said they fixed the issue with a software update. Recently, the vehicle has a ticking noise on the left side of the engine, and the engine idles so low, that it feels like it's going to stall. Those issues haven't been addressed at the shop, because I start a new job on Monday(12/4) and had to drive over 2k miles to get here. Thankfully the truck made it. Not a concern I should have with a brand new vehicle.

The vehicle was taken to the dealer, where the battery was disconnected temporarily to reset the ECM. The check engine warning light was reset; however, the failure reoccurred while driving. Additionally, the contact stated that the vehicle was experiencing abnormal fuel consumption. The contact stated that the fuel economy was 8.2 - 9 miles per gallon while driving and hauling a trailer. The contact related the failure to an unknown GM voluntary recall for Faulty Fuel Injector Flow Rate. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 400.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
