2024 Chevrolet Silverado 3500

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.

Email Subject I am reporting a serious safety-related defect involving sudden and complete vehicle shutdown while driving in a 2024 Chevrolet Silverado EV RST. Component/System Involved: The failure appears related to the 12-volt electrical system and associated vehicle control electronics. When the vehicle detects the 12V battery as dead or critically low, it immediately disables propulsion and control systems. The exact failed component is UNKNOWN. The vehicle is available for inspection upon request. Incident Description: This failure has occurred twice under similar conditions (ambient temperature approximately 25°F). On November 28, 2024 and again on January 2, 2026, after driving approximately two blocks at low residential speeds, the vehicle abruptly and completely shut down while in motion. In both incidents, the shutdown was immediate, without warning, and accompanied by a loud thud and an extremely abrupt stop. Safety Risk: In both incidents, the vehicle became completely immobilized in the roadway. I was unable to steer to the side of the road, restart the vehicle, or shift it into gear to move it out of traffic. This created a significant risk of collision. A similar failure at highway speeds could result in a severe or fatal crash. Warnings or Prior Symptoms: No warning lamps, messages, alerts, or other symptoms appeared prior to either shutdown. Problem Confirmation or Reproduction: The issue has occurred twice under cold-weather conditions. Inspections: After the first incident, the 12V battery was inspected and no issues were found. Following the second incident, the vehicle is currently being inspected at a Chevrolet dealership. No police or insurance inspections were performed. This behavior suggests the vehicle lacks a fail-safe or degraded-operation mode for 12V system failure and instead performs an immediate shutdown while in motion, which may represent a serious safety defect warranting investigation.

The contact owns a 2024 Chevrolet Silverado 3500. The contact stated that while driving 30 MPH and attempting to depress the brake pedal, the message “Trailer Brakes Disabled” was displayed. A dealer was contacted. The vehicle was taken to the dealer, and the contact was informed the contact the vehicle was operating as designed, and that neither the vehicle nor the trailer would be diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure and opened a case. The approximate failure mileage was 12,000.

When driving my truck and towing a trailer which has elec. over hyd. brakes and trying to stop. My truck will disable my brakes on my trailer, which may weigh 3+ times the weight of my truck. GM had a recall on the truck brake module which fixed my problem. Then l took my truck back for an oil change a few months later and they said that there is a open recall on the brake module (NEWER UPDATE) which once again caused my brake issues again with the newer recall. l have opened up a complaint with GM and they say take it to a GM dealer. The dealer checks the truck out and says there is no problem with the truck. They tell me that l need to install a module on my trailer ,which l did early on with the problem. l did own a 2017 chevy and pulled that trailer with NO issues. The trailer dealer hooked the trailer to a 2018 GMC and a 2016 Dodge pick-up. And had NO problem with the trailer brakes and put a NYS inspection sticker on my trailer LAST MONTH. We !! the trailer dealer and myself have spoken to the company ( brake module) that GM says that l need. This trailer brake module which the trailer dealer installed in Feb 2024 still did not fix my problem. The brake module company told me GM has His words a HORNETS NEST problem with this issue. Someone is going to loose there brakes and KILL somebody or a family Thank You for any HELP [XXX] Please contact with any feedback or info INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2024 Chevrolet Silverado 3500. The contact stated that while operating the vehicle, no audible sound was coming from the infotainment center. During the failure, the audible turn signal was inoperable and the warning messages from the infotainment center could not be heard. The contact stated that the OnStar Service would not connect and was inoperable. The vehicle was taken back the dealer to be reprogrammed several times, but the failure persisted. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 100.

After replacement of the trailer brake controller for the well known issue of the new OEM trailer brake controller disconnecting from the trailer brakes, the issue still persists. The trailer brake controller should remain connected to the trailer brakes at all times instead of disconnecting under its own control and programming. It is a major safety issue to be trailering a 21,000lb trailer with 6 functional disk brakes and have the controller decide to disconnect at seemingly random times to include descending a mountain pass at highway speeds.

The contact owns a 2024 Chevrolet Silverado 3500. The contact stated while driving at an undisclosed speed and towing a camper, upon coming to a complete stop, the message "Brakes Disconnected" was displayed. The vehicle returned to normal functionality, but the failure became a regular occurrence. No other warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure a failure with the brake control module. The vehicle was repaired, but the failure reoccurred. The vehicle was taken back to the dealer, who again diagnosed a failure a failure with the brake control module. The vehicle was repaired, but the failure reoccurred. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 200.

While traveling with a 5th wheel camper (Grand Design), that has solar panels the brake controller stops providing a connection to the trailer brakes. This is a know problem of the 2024 Chevrolets and so far there is not a fix that I know of. This is a big big safety issue because the trailer is heavy and hard to stop. The documentation from Chevrolet states the issue is once the battery charges and has a higher voltage than the truck battery it will surge the system and deactivate the braking system on the camper. This also hold true when the camper battery is too low, again the truck battery will surge the system and deactivate the braking system on the camper.
