The cab brake light works. The turn signal flasher works and the dashboard turn arrows work but the flasher goes to hyper flash. The emergency lights do not work, the flasher switch works. The turn signal in the mirror left or right does not work. I really do not know how long this has been going on.

I was driving down the road at approximately 55 mph when all of a sudden, my truck decelerated and a warning signal displayed on my dash indicating my speed was being forcibly reduced to approximately 30 mph. Fortunately, I was on a rural road versus the interstate. I pulled over and had an OBD2 reader. The reader indicated I had a P-2138 error code from a "voltage correlation error between the two Accelerator Pedal Position (APP) sensors". I was able to limp along with emergency flashers to return home. After driving approximately 10 miles, the "issue" resolved itself. I have since replaced the gas petal assembly after learning this is a common failure on many years of the Chevy Silverado series.

My truck went into limp mode with pulling a trailer on the highway due to a wide known injector pigtail failing. The truck would not accelerate, started shaking and lost speed suddenly. After resetting the DTC on my computer, each time the truck would hit a rough spot on the highway and vibrate, the truck would go back into limp mode. After getting the truck repaired at $566.67 cost, the dealer say they would not help with the cost. Said the federal safety agency would have to force them to fix this now issue. This was not a cheap truck and GM should not have there customers at risk in traffic with a know Limp Mode issue.

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.

Rear defroster would smoke/smell hot when activated. The symptoms were brought to the attention of the Dealership prior to window breaking, but nothing was done due to the VIN not being part of the listing. Now I have no rear window and parts are on backorder with no ETA. Not to mention this will be out of pocket costs that could have been prevented. This Glass shattered all over my [XXX] old daughter.

I purchased the 2019 Chevy Silverado 2500 Duramax on July 3rd with 60,000 miles on it and it is in great condition and so great for the price. Then about a week later I had to pull a trailer and it started to ding and say Warning check trailer wiring and then it would say trailer connected and it would go back and fourth ever 5 seconds and would be dining the whole time. I had to drive like that for 4 plus hours and it was very distracting. I was not able to check my speed, get phone calls, control my volume, and many other things which makes me very mad. This is a safety hazard for people in the vehicle and people around us. I really this that Chevy should make this a recall because there are so many people that have this problem and it is very dangerous for people because it makes you take your eyes off the road so much. There are a lot of people that will not tolerate listening to the dinging noise and they will unplug the trailer and they will have no break lights nor blinkers because they do not want to listen to it and that is even worse. Especially when there is a lot of traffic people are not able to see if you are breaking or not and that is when accidents occur. If a lot of people keep having this happen they will on want to buy these vehicles anymore that is where I am at. I am thinks about getting rid of it and staying away from Chevy and GMC.
