2024 Chevrolet Silverado 2500

While towing my travel trailer at 55 mph the truck rear tires locked up causing an alerting situation. The transmission automatically shifted out of tow/haul mode, the CEL illuminated and the following message appeared on the dash "reduced acceleration condition, drive with caution". This event happened a total of 3 times within a 20 mile distance. Because it was a short burst and I was traveling on a straight section of roadway, the risk of accident was moderate. This would have been a high risk of danger if I were on a curving downhill section of roadway. The situation was confirmed by my local dealer through a diagnostic check exhibiting a P0747 and P0700 error code. There were no CELs or other warnings prior to the lockup. The diagnosis was a problem with the transmission valve body. A new valve body was ordered and arrived 14 days later. After the new VB was installed the symptoms appear to be gone after driving about 50 miles.

The contact owns a 2024 Chevrolet Silverado 2500. The contact stated that the trailer brake control module failed to operate as needed while hauling a trailer, causing the trailer to lose braking capability. The vehicle was taken to a local dealer where it was diagnosed, and the contact was advised that the trailer control module was faulty and needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure. The approximate failure mileage was 63,500.

Truck went into “Reduced Acceleration” or “Limp Mode” while pulling my camper. Took truck to Kool Chevrolet in Grand Rapids, MI. They confirmed it is a bad Valve body on the transmission. No estimated time from Chevy on getting a replacement valve body. They confirmed this is a widespread known issue and could be weeks if not months. I have a family camping trip planned for the upper peninsula of Michigan in mid July and they aren’t giving not giving me any indication that I could have my truck back by then.

I bought my track about a year ago. Within the first week of owning it. Multiple times a week, when I start it there is no sound. No radio, music, blinkers, etc. Absolutely no sound. Some of the time once I get to where im going, turn it off. Once I start it again it's back. The other times takes a couple times to hear it again. When I asked the dealership, I was told it's a known issue. 9 months later it still does it. Some weeks once or twice. Other weeks up to 10 times. I pd alot of money for my truck and yes I expect it to have no problems like this.

With 19,000 miles on my Silverado 2500 HD I was traveling down a hill towards a stop sign at a T intersection. About 100 yeads from the stop sign I had many flashing errors on the dash, very little brake and very little steering. The engine just shot off. Fortunately I was able to stop the vehicle right at the stop sign while traffic from right and left had no stop sign. The truck would not start after. It did have electrical power. I tow was needed. The next day the Chevy dealer did find a bulletin for a wire in the engine compartment chaffed. Symptoms were the same as what I experienced. Repair was made. Bulletin #24-NA-124. There is no doubt a bulletin should be issued but I believe this is a real safety issue with the engine just randomly shutting off leaving no power to brakes and steering. Had this happened while I was towing our camper I would not have stopped and t boned another vehicle causing damage and no doubt injury to others and myself. If traveling on an interstate at 70 MPH this could have been even worst. This is a known problem and should be a recall and not just a bulletin. Thanks.

I was making a right turn and my signal started flashing faster than normal and stated service passenger front turn lamp. There is no way of service without replacing the entire headlight which is $2000.00 for one side. Took to gm dealer about a month ago to diagnose the opposite side and they stated warranty will not cover it. The truck had approximately 76k miles on it when the driver side was looked at and the passenger side was with 78k miles. I have contacted gm warranty claims department twice now to put it all on record. It’s a major safety concern when I have no turn signals on the front which could easily cause a crash. It also is a concern of being pulled over by any law official for something that I can not control and it’s not like I can just go to a local parts store to get a bulb on a weekend due to a poor design by General Motors. Other trucks of the same year with the same headlights that I have are being recalled due to the same issues but since my build date doesn’t fall into that category they do not want to take the responsibility of making things right or help prevent safety incidents from happening that could cause harm their customers and innocent bystanders

While pulling my Vilano fifth wheel trailer to Alabama from my home state of Texas the driver information center alerted me that the trailer brakes were disconnected. Then a short while later it alerted that trailer brakes were connected. This situation continued for the entire trip to Alabama. When the info center indicated trailer brakes were disconnected, they were indeed not working. Several times I almost rear ended cars stopping in front of me. (The vehicle had a recall notice urging to take it in and replace the brake module shortly after purchasing it. I did this.) Once I arrived in Alabama I took the vehicle to the Chevrolet dealership in Foley, Alabama to check the braking system. They told me there was no problem with the braking system. I retrurned to my home in Little Elm, Texas with the problem occurring the entire trip. I finally made it home and today took the vehicle to James Wood Chevrolet in Denton, Texas to have the braking systme checked again. They told me there was nothing wrong with the braking system. The service writer did say that because the trailer has LED lights the braking system does not recognize the voltage from the trailer and that is why the brakes are disconnecting. Please help me find out how to correct this extremely dangerous condition while I am towing my 16,000 pound fifth wheel trailer.
