2024 Chevrolet Silverado 3500

The Engine Cooler has a know defect that GM has put out service bulletins for. The engine cooler is cracking, mixing oil and antifreeze that is creating a sludge that runs thru the entire system. GM wants techs to attempt to clean/flush the engine before they approve a new engine to be ordered under warranty. GM is aware of the problem and there should be a recall out on the problem according to the service manager I spoke with at the dealership my truck is at currently. I was told the expected time frame is up to 3 months for the work to be completed, with no loaner available that is equivalent to the vehicle that went to the shop. The recall is necessary because if the engine has a major failure while driving it could cause an accident, if the vehicle is hauling a heavy trailer that could be detrimental because the truck can haul up to 40,000 GCWR.

The infotainment/control module in my 2024 Silverado 3500HD failed unexpectedly while I was traveling cross-country. The module is available for inspection upon request. Prior to the failure, I did not receive any warning lamps or messages. When the system failed, I lost access to multiple camera systems integrated into the vehicle, including backup and visibility-assistance cameras used to aid lane changes, parking, maneuvering, and identifying obstacles around the truck. Due to the size and height of this vehicle, these cameras provide important visibility of areas that are difficult to observe directly, including pedestrians, cyclists, and children who may be below the driver's line of sight. The loss of these camera systems reduced situational awareness and increased the risk of a collision while backing, changing lanes, or operating the vehicle in crowded areas. The failure also disabled navigation, hands-free functions, audio, WiFi connectivity, and access to vehicle settings controlled through the infotainment system. The vehicle was inspected by a Chevrolet dealer in Cape Cod, Massachusetts. The dealer attempted a software reflash to correct the issue; however, the procedure rendered the unit completely inoperable. The dealer confirmed that the module required replacement and quoted an estimated repair cost of approximately $1,500. The required replacement part was unavailable, and despite contacting numerous Chevrolet dealerships, I was unable to obtain a repair during my trip. As a result, I was required to continue operating the vehicle while towing a large trailer for an extended period without the camera systems and related functionality. I have also become aware of GM Service Bulletin PIC6630B, which indicates that GM has identified this failure mode and that it is not an isolated occurrence. Given that a single module failure can disable multiple safety features, I request that it be evaluated by an independent authority accordingly.

I was driving down the XXX Expressway Sunday, XXX, with my children in my vehicle. This is a very heavily traveled highway in [XXX] with heavy traffic. My 2024 Chevy Silverado 3500 Diesel HD Truck with 25,500 miles suddenly started throwing multiple codes, lost power, and steering. Fortunately I was able to "roll into" the emergency lane while muscling the steering in that direction and engaged the emergency brake. My other son was following shortly behind me in his vehicle and pulled over to assist us about 30 mins after my truck was sitting stalled in the HWY. He parked his truck behind mine, put on his hazards, and we were transferring gear from my truck to his truck. At this point my 2024 Chevy HD Silverado Diesel started rolling back on it's own and nearly crushed my son's friend. The parking break was on and it suddenly released on it's own. It took 3 grown men to stop it from crushing my son's friend. The force was so strong that when he lifted his hand to try to stop the truck from rolling, it broke the right rear tail light. He could have been crushed between our two trucks from this situation. I have never been notified by GM of any recalls, however, the truck had to be towed to Ferman Cheverlotte service on Adamo Dr, Tampa Fl and is currently sitting on their lot. I was told by the service tech Michael Stevens that the vehicle had several open recalls that they would address but did not offer any information about what could be wrong. After searching online, I found that GM IS aware of this issue and sent several service bulletins about this exact problem. I had contacted the Ferman service center the week before to bring the truck in because the AC was out and made an appointment for service on Tuesday. The day after I made the appointment my batteries died and had to be replaced by AAA.It is disturbing to know GM and FERMAN Service centers are aware of this safety issue on these HD trucks and never informed me, the consumer.

REAR WHEEL LOCKUP: While driving down the highway pulling a loaded trailer the rear wheels locked up, GM has an open recall on 2020-2022 models but denies its an issue with the 2024 model, my dealership pushed a “software update” but that does not fix the faulty transmission valve body issue, it just overrides the safety features that were designed to protect the transmission. I have a video of it occurring while slowing down for a stop sign when it did it the second time to me.

The engine oil cooler failed causing engine oil to leak into the coolant system on my 2024 Chevy Silverado 3500HD. This requires a full replacement of the coolant system. In addition, excessive sludge buildup inside the motor is caused. This is a known issue with GM for 2024 Diesel vehicles. GM has released a service bulletin but is fighting my local dealership on the required repairs.

No Owners Manual came with my Truck. I was made aware of Safety Recall 25V815 (Manufacturer Recall N252532020) which addressed 2025-2026 cars and trucks. Currently my 2024 is not included. I can confirm my dealer did not receive any owners manuals for most cars and trucks in 2024. I notified Chevrolet Customer Service and they did not assist. They Dealer was unable to assist and would not reimburse me for the Owners Manual I purchased. I am requesting reimbursement for the purchase of an Owners Manual.
