  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 NHTSA 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 NHTSA investigate whether the recall programming is causing electrical module failures and whether additional action is needed.

  The contact owns a 2024 Chevrolet Silverado 2500. The contact stated that after parking and turning off the vehicle, the tailgate inadvertently unlatched and opened. The contact stated that the failure was caused by a short-circuit in the tailgate electronic gate switch due to water entering the unit. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact related the failure to NHTSA Campaign Number: 24V894000 (Latches/Locks/Linkages); however, the VIN was not included in the recall. The manufacturer was made aware of the failure and advised the contact to report the failure to the NHTSA Hotline. The failure mileage was approximately 42,000.

• 12/02/2023· ELECTRICAL SYSTEM,ENGINE,BACK OVER PREVENTION

  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.

  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.

• 11/22/2024· VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE

  While using adaptive cruise control, the system can detect a vehicle and immediately apply the brakes or slow down. In some cases, it may detect a vehicle (the vehicle icon appears) and trigger an immediate red collision light flash, followed by automatic braking. However, during these events, there were no cars ahead of the vehicle. There was no obstruction of sensors or cameras, and the incidents occurred in various weather conditions, including rain, snow, and clear days, both during the day and night. If the road is slick or slippery, this could potentially lead to a loss of control. Additionally, if another vehicle is following closely behind, it could result in a collision.

  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 was towing a dump trailer with gravel in it down a gravel road grade (downhill around 5-7mph) and received a warning on the DTC about the trailer brake being disconnected. All of the lights on the trailer were still working, however the trailer brakes no longer functioned and all of the braking was transferred to the truck. The trailer slowly pushed the rear end of the truck around causing the vehicle to jackknife and causing significant damage to the bumper and bed. After researching this post incident, there appears to be numerous complaints and TSB from chevy regarding a faulty brake controller when towing a trailer where the voltage can backfeed into the vehicle causing the vehicle brake controller to disable.

  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.

  This truck was optioned with the trailer tow package which includes a trailer brake controller. However, if the battery on the trailer is a higher voltage than the truck battery, the trailer brake controller will fail intermittently. This leaves the truck traveling at freeway speeds with no trailer brakes. This is EXTREMELY UNSAFE. GM is aware of the problem and has issued a technical bulleting "23-NA-113 Information on Trailer Brake Disabled or DTC Stored" on June 28, 2023.

  While pulling fifth wheel camper the the electronic brake controller looses connection and brakes on the trailer do not work leaving only the truck brakes to stop both truck and trailer. General Motors claims this is caused due to the solar panel on the trailer charging the trailer battery more than the truck battery which back feeds into the system. This problem only occurred on the 2024 models. The same trailer was pulled with a 2021 model with no issues. This is a known problem which Chevrolet has a service bulletin stating such.

  The differential, front right axil "housing" is rusted to the point that it is pitting. The rust completely covers the entire right axil housing and does not come close to matching the light corrosion when compared to the rest of the differential or anywhere else on the vehicle. These indicators lead me to believe the housing was in a corrosive environment prior to being installed onto the differential where both the internal and external surfaces of the housing were exposed to same corrosive environment. Several concerns: If the inside of the axil housing is rusted as bad as the outside, the integrity of the axil has been compromised; Internal rust contamination will lead to premature failure; the housing was not properly heat-treated; no vehicle should be delivered brand new with this level of rust on any part. The issue was pointed out to GM shortly after purchased new. The vehicle has been kept in a non-corrosive environment since it was purchased, and GM refuses to assess the internal integrity of the axil housing and refuse to install a new housing. I am cautious about towing heavy loads since I do not want risk towing 21,000 lbs. if or when the housing fails. I have seen other Silverado, 2500 HDs with the same issue. As an experienced Airframe and Powerplant mechanic with automotive experience, I would never allow a vehicle to operate with this level of contamination unless I could confirm the integrity of the housing via nondestructive inspection and thickness measurements. Or should I just start towing and wait to see if it fails?

  When truck is connected to a trailer with electric brakes, intermittently a check trailer wiring warning flashes on the dashboard screen. When this happens you do not have trailer brakes. It has happened on multiple trailers with 7 pin connections. I have taken it to the dealer twice with no fix other than GM recommending a non GM trailer receptacle. I have taken my trailer to the dealer and they could find no problems. Basically the 2024 Silverado 2500 HD when hooked to trailers with industry standard 7 pin 12 volt receptacle loses trailer brakes. This condition potentially is fatal and a definite hazard to public safety on roads. problem was reproduced at the Chevy dealership in Pensacola Fl.
