2024 CHEVROLET SILVERADO 2500 Complaints

While driving the transmission shifted very hard felt like it was going to shatter or lock up this happen twice. It also lacked power due to not shifting properly. It coded for transmission issue. I spoke to 2 different Chevrolet dealers service writers, the 1st did noy have a transmission but told me this was a known issue that the valve body for the transmissions fails and recommended another dealer. The dealer notified transmission valve block failed a known problem with the valve block being on back order due to this issue. The truck know sits at the shop awaiting repair. If the transmission fails or locks up in a 2500 truck, could be towing a trailer like I was, would result in an accident.

Owner from brand new (16 miles) multiple complaints through ownership of harsh shifting, jerky throttle on and off, excessive engine braking, and have been stuck on the side of the road 3x due to the same situation. Never was a code thrown so I was continuously told there’s “nothing wrong.” On [XXX] I was driving [XXX] out of Denver making the climb towards [XXX] to home. As I had my cruise control set at 65, out of nowhere my truck locked up what seemed to be the rear wheels completely, causing my rear end to sway violently. I immediately slowed down and pulled over with no indications or lights being illuminated on my dash. I turned the truck off and let it sit for 10 minutes and restarted it. Having no issues I signaled back onto [XXX] and the truck accelerated to nearly 65 with no issues. As I hit 62 on the dash it again locked up the rear tires. I again pulled over, this time questioning what could be causing this, knowing the first time indeed was what happened. I put my truck into park, and still had no warning lights or check engine light. I then put my truck into neutral and then clicked the auto button thinking maybe something with the rear end is locking my brakes up. Upon doing so I again entered the roadway, big mistake on my part as this time upon reaching 60+mph all 4 tires simultaneously locked up. How I didn’t roll, I have no idea. Easily the scariest set of events I’ve ever faced while driving and that’s considering all of the insane drivers on our roadways today. I literally lodged a complaint with Chevrolet the same day I bought this truck before ever even leaving the dealers lot, and have had zero communication from them other than myself reaching out. They have ignored the problem literally from day one and it easily could’ve cost me or someone else their life. I’m appalled that to date they are still selling these trucks, replacing the valve bodies with the exact same faulty ones, and allowed to put others in danger constantly. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

The truck went to the dealer for recalls on March 21, 2025. The Truck is still within the bumper-to-bumper warranty. Recalls consisted of tailgate fix, TCM & ECM updates. The truck was returned to me approximately a week later. I noticed a significant loss of power. I took the truck back to the dealer and told them about the issue. They had it another 2 days and returned it to me, saying there was nothing wrong. Approximately a week later, I was driving down the road and the check engine light appeared on the gauge cluster. I immediately drove the truck to the dealer, and the DTCs were emissions-related. The service advisor, Jeff, told me to keep driving the truck, and it might go away. I drove the truck home, 20 mins away from the dealer, and as I pulled into my driveway, a message on the gauge cluster said, "Add engine oil." I notified the Dealer of the issue immediately. The next morning, I added a gallon of oil, and there were still no signs of oil on the dipstick. At that time, I noticed there was no coolant in the reservoir, but engine oil residue, and a collapsed upper radiator hose. The truck was towed to the dealer later that day. After inspection, the dealer said the oil cooler had failed. They sent me the service bulletin, but that bulletin only says, "oil and coolant mix," nothing about the disappearance of the fluid, and no explanation of the emissions codes. The dealer and GM's corporate office are refusing the share the diagnostic data on how they have concluded that the oil cooler has failed. Their solution is to replace the oil cooler and see what happens. This truck has 1000 miles left on the warranty, and the parts/procedures expire at the end of the bumper-to-bumper warranty. Recap: GM will not share diagnostic data, and they are refusing to extend coverage, yet their remedy is to experiment with my $70,000 truck, and the moment this truck is out of warranty, they are going to wash their hands of it. That is not acceptable.

Brake pad failure, at 22,000 miles brake pads are almost worn out and leave extreme amounts of brake dust on wheels. This issue has been happening since 500 miles. Was told by dealer that it's a cheaper pad that the manufacture uses and the wear is normal. Steering wheel shakes when brakes are applied and when you're pulling a load the vehicle starts vibrating and jumping. Now rotors are warped due to the faulty pads wearing out so soon. Dealer and GM refuses to fix it, dealer says it's not covered and not a safety issue and GM has no explanation for their rejection the claim.

When hooked to 5th wheel trailer the brakes work good for a day then info center says check trailer brakes. The trailer bakes are not operational at that time. A few minutes later trailer brakes are back working again.The truck keeps shutting off the trailer brakes and sometimes they do not come back on at all. It happens every time I hook up to 5th wheel trailer. I have had it back to dealership 6 times and they can’t fix it.

While towing our 25ft travel trailer, I began getting warning from the trailer brake controller which repeatedly disconnected and, thankfully reconnected them after a brief interval. Luckily, the times when I had no trailer brakes did not require rapid stops. That said, towing a 7000 # trailer thru the mountains in a driving rain storm with no brakes randomly caused a bit of concern. After researching this I find this is a known defect and has TSB’s and voluntary recalls in place. (TSB 23-NA-149 and N232414840 respectively) However I was never notified by GM as my VIN was not included in the above. We could have been seriously injured or worse. This tsb is almost 2 years old. Why were we not informed/included? Our issue is identical to the tsb.

I purchased a 2024 Chevrolet 2500 HD Crew Cab High Country and reported harsh shifting after 3 months 3,000 miles and told that nothing was wrong. Brought truck back in in February 2025 with 12,000 miles due to erratic shifting and loud whining noise. After 4 days in the shop they agreed that there was a problem but didn't know what the problem was. One week ago on Sunday 3/23/25 While driving the engine would rev up for acceleration but didn't speed up. Got to my son's house two miles away. I went leave 20 min. later and the transmission died completely. It would not go forward or reverse.
