general problems of the 2024 Chevrolet Silverado 3500

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.

Trailer brakes and lights come and go. I start with having everything then loose brakes and lights when I’m driving. This is apparently a known issue that they have a fix for but I have never received anything about a recall.

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.

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.

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.

There is an electrical / turn signal and trailering issue. Not towing- the right turn signal gives a rapid flash when the automatic headlights are activated or in off position. The rapid flash goes away when manual headlights are used both running lights and on. Although the light still works with a rapid blink, there is a dash error message and it’s impossible to know while driving if the error is real or not. This issue is intermittent when auto headlights are selected. Towing- bigger safety issue. The trailer lights only work properly when headlights are in auto mode and daylight. When it gets dark, the headlights turn on and error messages happen and trailer lights go out. There are also error messages when manual running lights or manual lights are activated. Thus it appears there is no way to tow an RV safely at night. This did not occur on my 2021 chevy 3500. These issues are wide spread but gm is doing nothing about it. Please help me, the other owners, and the public from these dangerous vehicles.

I believe my def heater has stopped working and my full def tank is now frozen. I’m now stranded in the middle of south dakota in -29 degree weather. My truck will not drive. Or idle for the heater to keep me warm because the def is required for engine to run.

Recently purchased a 2024 Chevrolet silverado hd3500 and use it to haul a 40' 5th wheel toyhauler. Several instances when I connected the RV electrical cord to the truck I would see a "check trailer wiring" message. Along with this message I noticed there was no current going to the RV brakes. I had several technicians look into matter, but could not find a resolution. Later my brother sent me a youtube related to this problem. It appears that if the RV has solar cells for power or the RV generator is running, the voltage on the RV battery is affecting the truck sensors and disables the brakes. This can be a life threatening issue for the vehicle driver or others on the highway.

We have a 2022 grand design imagine 22mle and when we tow it with the truck we are getting the intermittent message on the dash that the trailer brake wiring is not connected. It continually connects and disconnects as we tow and press the brakes on the truck. We previously towed the camper with a 2011 silverado 1500 and did not have this happen. We took the truck back to the dealer for a service check and they had no answered for us. This is a serious safety concern while we are towing an extra 6,000 pounds behind us.

The contact owns a 2024 Chevrolet Silverado 3500. The contact stated while driving 30 mph towing a trailer and depressing the brake pedal, the trailer failed to slow down as intended. The contact was able to continue driving to the destination. The vehicle was taken to the dealer and the contact was informed that an undisclosed electrical module needed to be added to the vehicle. The vehicle was not repaired. The manufacturer was contacted but no assistance was provided. The failure mileage was 2,800.
