2024 Chevrolet Silverado 2500 electrical complaints
Page 2 of 3: complaints 11 to 40 of 56, newest first, as owners wrote them.
Very limited while driving in the dark cause head lights go off and can’t drive in the rain or snow cause wipers turn off not save for my family and I and other drivers on the road Thai all happen, After the dealer (Lithia Chevrolet of Redding, CA) performed GM recall programming on the Serial Data Gateway Module (SDGM) and related software updates, my truck began having serious electrical failures. Immediately after the recall work, all exterior lights, interior lights, and trailer lights began flickering on and off while driving. The windshield wipers also pause or stop for a moment when this happens. None of these issues existed before the recall. This appears to be a module reset or corrupted calibration caused during the recall reprogramming. GM has already told the federal safety agency that they have hundreds of field complaints about flickering headlamps on 2024 trucks, and they identified lighting flicker as a safety defect. My symptoms match those issues exactly. The dealer refuses to accept responsibility, saying the recall is “closed,” but the electrical failure only began immediately after their programming. This is a safety hazard when driving at night or in the rain, and it affects the trailer braking/lighting circuits as well. I have an active GM case opened for this issue. The truck is unsafe to operate in this condition. I am requesting that the federal safety agency investigate whether the recall programming is causing electrical module failures and whether additional action is needed.
Instrument cluster stopped working, I have no speed or fuel remaining indicators. Dealer completed software recall work which did not fix the issue. Replacement is on back order so I am unable to drive the vehicle for an unknown amount of time.
The contact owns a 2024 Chevrolet Silverado 2500. The contact stated that the trailer brake control module failed to operate as needed while hauling a trailer, causing the trailer to lose braking capability. The vehicle was taken to a local dealer where it was diagnosed, and the contact was advised that the trailer control module was faulty and needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure. The approximate failure mileage was 63,500.
Truck keeps losing trailer brakes, intermittent as i am towing a 10,000 lb camper. Very unsafe
I bought my track about a year ago. Within the first week of owning it. Multiple times a week, when I start it there is no sound. No radio, music, blinkers, etc. Absolutely no sound. Some of the time once I get to where im going, turn it off. Once I start it again it's back. The other times takes a couple times to hear it again. When I asked the dealership, I was told it's a known issue. 9 months later it still does it. Some weeks once or twice. Other weeks up to 10 times. I pd alot of money for my truck and yes I expect it to have no problems like this.
While pulling my Vilano fifth wheel trailer to Alabama from my home state of Texas the driver information center alerted me that the trailer brakes were disconnected. Then a short while later it alerted that trailer brakes were connected. This situation continued for the entire trip to Alabama. When the info center indicated trailer brakes were disconnected, they were indeed not working. Several times I almost rear ended cars stopping in front of me. (The vehicle had a recall notice urging to take it in and replace the brake module shortly after purchasing it. I did this.) Once I arrived in Alabama I took the vehicle to the Chevrolet dealership in Foley, Alabama to check the braking system. They told me there was no problem with the braking system. I retrurned to my home in Little Elm, Texas with the problem occurring the entire trip. I finally made it home and today took the vehicle to James Wood Chevrolet in Denton, Texas to have the braking systme checked again. They told me there was nothing wrong with the braking system. The service writer did say that because the trailer has LED lights the braking system does not recognize the voltage from the trailer and that is why the brakes are disconnecting. Please help me find out how to correct this extremely dangerous condition while I am towing my 16,000 pound fifth wheel trailer.
Intermittent loss of trailer brakes. Trailer has small break away battery
Intermittent lose of trailer brakes.
Intermittent lose of trailer brakes. Dealerships are unable to duplicate issue, will not replace under factory warranty. Chevy has not issued a recall for this specific vin. But other 2024 Chevy 2500 have had recalls for it. Would like a recall for my vin die to this being an issue if an accident occurs. Traveling with multiple 10K pound trailers and no brakes.
My trailer brake controller routinely does not allow me to adjust the brake gain. Multiple times (and on recorded video), I’ve had instances where I could not increase gain while hauling heavy loads in the trailer and this has caused me to lose my ability to stop the vehicle effectively. This has nearly cause accidents a few times while hauling on the interstate, and down my mountain road. The driver must be able to adjust trailer gain at any point while operating the vehicle. This issue has happened with multiple trailers. I’ve taken the vehicle in multiple times and had the brake controller components replaced but this issue still exists and the dealerships are unable to resolve. I was informed I have trailer issues even though this only occurs in this vehicle while towing and not other vehicles pulling the trailers. This is a major safety issue and will cause an accident if it isn’t resolved. My only option at this point is to purchase an aftermarket brake controller as my factory brake controller is unsafe. I have multiple videos of this issue and nearly had the trailer push me over my mountain from the issue. This issue has happened since I purchased the vehicle and continues to happen. There are multiple service records which show I requested the brake controller to be fixed. This isn’t a one time date or speed. I’m unable to upload videos I’ve taken on my phone but I can send them in. Reach out to [XXX] for videos. The manufacturer and service centers aren’t helping resolve this.

intermittent lose of trailer brakes.
Trailer brake control module in vehicle will have intermittent loss of trailer brakes. Dealership stated they will not fix the issue if they are unable to replicate it. Even with video or picture evidence. Dealership has been uncooperative during the process.

While driving with a trailer connected the display in the truck will say trailer disconnected. Then the light will go away and come back on. The trailer plug and the trailer are connected and the plug is tight. When this happens the trailer braking system is disabled (trailer has no brakes) I can plug the same trailer to Ford or Dodge with no issues. Have had the Chevy to the dealer 4 times now and they are unable to duplicate the problem. I have researched the problem on the internet and there are a lot of discussions of other people having the same issue. GMC has replaced the trailer control module, but this did not fix my problem. I am at the point the dealer and GMC are giving me the run around. I bought this truck for commercial use and frequently haul trailers. It is very unsafe when the brakes on the trailer are disabled.
I would like to report a hazardous issue with the 2024 Chevrolet Silverado trailer braking power mode. The trailer braking system turns on and off when the loaded trailer is connected; this represents a security hazard since this truck is used for work and we move heavy pieces of metal and glass. This issue was reported several times to the dealership Lou Bachrodt Chevrolet in Coconut Creek, FL. Also, the manufacturer provided a letter indicating the replacement of some parts. As indicated, I took the truck to Lou Bachrodt Chevrolet in Coconut Creek, FL, on [XXX] for the corresponding service; however, the truck is still presenting the same issues. We tried different trailers, including a U-Haul trailer, and still had the same dysfunctionality. Please advise how to proceed.

When pulling trailers I frequently get warning to check trailer wiring. I have gotten this warning with every trailer I have towed to include, my travel trailer(camper), livestock trailer, car hauler trailer and enclosed cargo trailer. It is intermittent but frequent. I am unsure if trailer brakes will engage during this failure.
The contact owns a 2024 Chevrolet Silverado 2500. The contact stated while driving at an undisclosed speed and towing a trailer, the trailer brake lights became inoperable. The service trailer brake system warning light was illuminated. The vehicle was taken to the dealer several times; however, the failure could not be duplicated. The vehicle was not repaired. The contact stated that the trailer was replaced with another trailer; however, the failure reoccurred. The manufacturer was not made aware of the failure. The failure mileage was approximately 26,000.
Charging system failed The system failed with no warning, we were traveling on a country curvy road and about to descend a grade. With the charging system failure, the truck lost power to brakes and steering. It's at the dealer, being inspected etc. No warning lights or message until the failure occured, then a battery light appeared and a charging system failed message.
While towing our camper that has solar power our trailer brakes would randomly disconnect. Sometimes for a few seconds but several times for several minutes. After checking all wiring, doing some research and trial & error we discovered that it is a problem with the truck and the solar on the camper that is making the brakes disconnect. This happens randomly but quite often and it happened to us several times while towing in the mountains of Colorado. It is definitely a safety hazard to not have the trailer brakes. We have towed the same camper with other trucks including the 2023 Chevy that we owned before this truck and have never had a problem.

Truck sends safety lights on dash one day and the next day they go off. Truck is running rough and has subpar fuel mileage driving 55 to 65 miles per hour. Esc light comes on and steering wheel changes sides to drive straight. Information screen goes black and flashes while driving. I have been in contact with gmc and they said I have to report to you before they will do anything. There was a recall for my type of Truck for poor fuel consumption but my vin was not included. I feel my truck has fell through the cracks and is in need of serious repairs. 72k for this truck and now I am having nothing but problem I feel used... please help!

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 the federal safety agency 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 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.
