Engine And Engine Cooling Problems of Chevrolet Silverado 2500 - part 2

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.

I was driving my truck and lost full power to the truck. Which happened as I was pulling out of a parking. The truck went into a limp mode. With the truck losing full power, it put my child and I into a safety risk. The truck got repaired at the dealership. The dealer was able to reproduce the issue. The truck was inspected at the dealership. Warning system did come on saying speed would be limited if (roughly 150 miles to a max 65mph). When I called another dealership, they said this was a normal thing for these trucks and chevy hasn't fixed it. I feel like if its a known issue with the wiring becoming free, why would they not proactively fix this issue before someone gets hurts from thinking they have the power to drive. The dealership that I took this too knew where to look right away as this is common.

In 2024, I noticed that my truck was experiencing rough shifts. It felt as if the back wheels were jerking over uneven ground, even though the vehicle was on a flat surface. In November 2024, my sister sent me an article about general motors' massive recall due to rear wheel lock-up, which increased the risk of crashes. I contacted gm and learned that my truck was part of the recall. I reported the issues my truck was exhibiting, and gm instructed me to reach out to my dealer about the problem. However, I was informed that they did not have the parts to fix the issue and had no idea when they would receive them. I asked gm if they would provide me with a rental vehicle, but they declined, stating that if they offered a rental to me, they would have to provide one for others as well, which was not feasible due to the large number of affected vehicles. I explained that my truck is my daily driver for work, and I frequently transport my grandchildren in it. Driving the truck was hazardous given the issues it was already exhibiting. I was told to contact my dealer, and since my truck was under warranty, they should provide me with a rental. When I requested to speak with a manager, I was informed that they would only reiterate the same information. I then contacted my dealer, sapaugh gm country, located at 1435 mcnutt st. , herculaneum, mo. I was informed that they do not have the parts. But they did a minor tweak which has caused more damage to my powertrain and engine.

Vehicle was towing horse trailer. Gave an indication message to check trailer break wiring. I did so and all was working fine. I loaded my horses and pulled out onto the road. Traveling 10 mph the truck completely shut off, no brakes, no warning, I helplessly rolled to a stop. The truck then turned on electrically, but did not start the engine completely by itself. Two minutes later, the truck turned itself off electrically. The motor was never running. I had it towed to a dealership in which it took them five days to repair. The truck has 17,000 miles on it. If I would’ve been traveling on the expressway or going any faster, I could’ve killed people. . I personally have ptsd from ever driving this truck hooked to a trailer again. There should have been some kind of warning system. I should have never lost my brakes. I purchased this truck as a towing vehicle from my horse trailer and now I am terrified to use it!.

Of course I had them do all the repairs and they found metal shavings all through out the fuel system. I was without my truck for weeks and had to pay ridiculous cost of almost $13,000.

On July 1st, 2023, I purchased a 2024 Chevrolet Silverado 2500 from orielly Chevrolet in tucson, arizona. On July 2nd, 2023, an error message popped up on the dash, “park assist blocked see owner’s manual”. It continued to happen on and off til this very day. The dealership "attempted" to fix the issue, but it obviously hasn't been resolved. Due to equipment being faulty, the chances of an accident whilst back up are significantly increased. At one point on this ordeal, the truck was in the shop for 61 days. It had been in my possession for 18 days. I am currently in the process of a buyback for the vehicle. I had to hire a lemon law attorney. A supervisor from gm advised that gm is refusing a buy back for the vehicle. The vehicle also displayed an error, "key not found" while I was driving at 50mph. A bit unsettling. That error showed up twice on the dash. The dealership said they fixed the issue with a software update. Recently, the vehicle has a ticking noise on the left side of the engine, and the engine idles so low, that it feels like it's going to stall. Those issues haven't been addressed at the shop, because I start a new job on Monday(12/4) and had to drive over 2k miles to get here. Thankfully the truck made it. Not a concern I should have with a brand new vehicle.

I was almost run over by a semi-truck when entering the freeway because my 2022 Chevrolet truck would not accelerate. I was told at the dealer the loss of power was intentionally caused by the onboard computer. It is programed by the manufacturer to do this anytime certain repairs may be needed. In my case, the life-threatening event I experienced took place because a sensor went out and the computer thought a repair was needed.
