2024 CHEVROLET SILVERADO 2500 Engine Problems

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....

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...

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,...

Complete engine and emission fail while driving. Complete loss of power. Created a serious safety issue while driving due to other traffic and inability to move vehicle from road side to safe area. Problem was confirmed by mechanic. Contact to GMC resulted in no response. Mechanic has reported numerous other GMC trucks with the same issue. Check engine light came on shortly before and then went off again. Contact was made with dealer as well as GMC directly regarding the issue.

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...
