2024 Chevrolet Silverado 2500

This vehicle has a severe transmission shift issue that will likely cause an accident at some point. This vehicle has an Allison 10 speed transmission and began shifting extremely hard or violently from 7th to 8th gear in November of 2023. This problem began when pulling a travel trailer that is weight rated well below the capacity of this truck. This hard shift causes vehicle occupants to lunge during the event and it is feared that a catastrophic failure will occur, resulting in a vehicle accident. The vehicle was taken to the dealership where purchased as it is still under manufacturer’s warranty, and in March of 2024 the dealership performed a software update and transmission “re-learn” which solved the issue until the truck was used to pull a travel trailer again. The issue returned in November of 2024. The truck was returned to the dealership for follow up but the dealership has not taken any further action to resolve the problem at this time. There is a service bulletin (N242467600) issued from GM that seems related to this vehicle but I’ve received no notification that this vehicle is eligible for transmission replacement under this service bulletin. This issue will likely result in a personal injury or vehicle accident at some point.

steering wheel has excessive play. i have had it looked at by two different dealerships and they are trying to convince me that this is normal. there is about 1 inch of dead band in the straight-ahead position. the dead band movement of the steering wheel shaft does not move the pitman arm at all. the last time i took it to the dealership i asked if they could check the over center preload on the steering gear. they said they checked it and it could not be tightened any further without causing secondary problems. I do not believe they performed the actual adjustment as it would have required the steering gear to be removed and adjusted on the bench. the free play results in delayed corrections in correcting for lane drift. i have driven similar trucks and there is very little if any free play. this issue has been present since new.

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 contact owns a 2024 Chevrolet Silverado 2500. The contact stated that while driving at an undisclosed speed, the vehicle briefly jerked and then jolted. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to a dealer, who was unable to duplicate the failure; however, the contact was informed that the power train control module was reset. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline to report the failure. The failure mileage was 50.

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. Currently working with insurance to come up with a damage quote. Bulletin # 23-NA-149

Transmission failure on interstate i90, truck down shifted violently and check engine light came on and warning on dash read speed reduced drive with caution. Took truck to gm dealer on August 1 2024 who said the transmission shift solenoid plate has to be replaced. Gm dealer still has my truck as of October 16 2024 and all I they can tell me is that the part is on back order and they have no idea when it will be available. This could have caused a serious accident as I was also towing a 3500 lb trailer at 65mpg at the time with the speed being reduced so quickly by the failure.

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.
