After 3 days of using the truck I parking the vehicle with a trailer and I stop the truck and turn off to check the back and when I try to start the engine don’t work and all the lights turn on low battery,no key,service service esc, traction control, and I stuck with the whole cabin outside of the drive way , pedestrians must use the street to instead of the sidewalk, take it to the dealer and they say it is the computer must be replace it .

Truck has been in and out of the shop since July. For more than 70 days total. I received a printout from a Chevy dealership in Georgia that indicated the main computer system lost communication with other components 11 times. It indicated it lost communication with the brake system control module three times and lost communication with the engine control module twice. Not sure exactly what that means, but it sounds rather serious. I've been trying since July to get GM or the dealership to buyback or replace my vehicle. Neither had ANY interest whatsoever. After I provided the attached photo to GM, they decided to buy my vehicle back. Seems that this issue is bigger than I know and surely needs some oversight from NHTSA so no one gets seriously injured due to GM's carelessness to address issues when they were brought up.

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 contact owns a 2024 Chevrolet Silverado 2500. The contact stated that while starting the vehicle, the check engine warning light illuminated. 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.

The contact owns a 2024 Chevrolet Silverado 2500. The contact stated that while hauling a travel trailer at various speeds, the check trailer wiring warning message intermittently flashed on the instrument panel. The contact had taken the vehicle and the travel trailer to the respective dealers; however, neither dealer were able to determine the cause of the failure. Upon investigation, the contact discovered a TSB: 23-NA-113 which he linked to the failure. The bulletin stated that the travel trailer brake might become disabled due to a solar panel battery charger. The contact stated that whenever the trailer battery was fully charged and had a higher charge than the vehicle’s battery, there could be a back feed into the trailer brake power module causing a shutdown. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 1,500.

The integrate trailer brake control system malfunctions when a trailer equipped with solar panels is hooked up. I recently rented a newer travel trailer and kept on getting a warning that the brake control system was disengaging. Every 30-60 seconds the system would connect and the quickly disconnect. I troubleshooted by hooking up a trailer without solar and the brake controller worked as intended. I also troubleshooted with the trailer by hooking up a 2015 Ford F-350 and the trailer brakes worked as intended. This is a known issue among the 2024 Chevy 2500 and 3500 owners that have reported the same issue. Replacing the trailer control system does not fix the issue.

The GM brake controller will disconnect with the trailer being pulled. You get a message on the information center that the brake controller has lost connection with the trailer or no trailer brakes are available, something to that effect. This has happened up to 5 times in one day. You never know when this will happen. Pulling a 7,000lb trailer and not knowing when you will have 'no brakes' is dangerous. I bought the truck to pull my RV trailer, now am afraid too. I brought my truck into a dealer and first was told "the issue is in the trailer". There is a bulletin saying the issue is do to 'the solar panels or solar generator', I have nether, just one lead acid battery. Then was told 'they don't know what they can do'. I've been in contact with other that have the same make, model, and year that is having the same issue ! I now have a very expensive vehicle that I can't do with what it was advertised it could do !!!

Instrument Cluster screen blinking On/Off and showing "Service Instrument Cluster" message. Lost all indications of speed, warnings, gauges, gear selection. Could not tell if vehicle was performing correctly. All sensors appeared to be working, but indications to driver missing.
