2023 CHEVROLET SILVERADO 1500 Complaints

At 19k miles the transmission had a shifting problem and went into limp mode forcing a deceleration while on a highway. Had to unhook the battery and hook it back up to clear the code to get to a safe point for towing. Had to do this 3 times. Once at the dealer they could not recreate the problem. One week later it went into limp mode again. Took it to the deal and was informed that the valve body in the transmission would need to be replace. There is a supply shortage on parts and I am now without a truck for who knows how long.

While accelerating from a traffic signal the transmission shifted very hard and caused the vehicle to suddenly lunge forward.

During gear down-shift the rear wheels briefly lock up. This event can be duplicated easily at around 45mph, by slowing due to uphill grade or slowing traffic, then upon normal application of throttle to resume course the transmission shifts to next lowest gear (3 or 4, not sure) there occurs a brief and sudden horrendous jerk as the rear wheels lock & skid. The event lasts less than 1/4 sec, but happens multiple times per day as that speed/load condition is frequent. On occasion, the same can occur in a parking lot ~10mph, but isn't as violent. The first occurrence was at mileage 38,000; the vehicle now has 45,000 miles. This appears to be the same issue as NHTSA Recall No 24V-797, which does not include my vehicle's production year.

The symptoms since the beginning of 2024 have been that when braking between 7 and 10 mph, you feel a bump or a skid, and when you stop, the engine shakes for a moment as if it's going to shut off. This happens with the Auto Stop-Start off. A sudden braking moment can affect the vehicle's performance, making it difficult to control and increasing the risk of accidents, especially when it comes to a pickup truck that may have a trailer with cargo or objects in the bed that can be thrown. The trailer can even leave the road, losing control of the car. In 2024, I took the truck to the place where I bought it, Bomnin Chevrolet Dadeland, for a checkup. I explained all the symptoms to my advisor, just as I do here. I had to take it to wait for a loaner. A few days later, I took it back, and they had it for almost a week. When I picked it up, my advisor told me everything was fine. When I left the dealership, I found the same symptoms, so I went back and told him the car was still doing the same thing, and he told me it was normal. After much insistence, he got in the car with me to show him the problem, and the car did it several times, but according to him, it was normal. Now, in 2025, a week ago I took it to Miami Lakes Auto Mall to get checked out with the same symptoms and explanation. I started investigating why that couldn't possibly be normal car operation. They found they had to replace the torque converter and valve body because they found an excessive amount of metal in the transmission. The valve body is on back order indefinitely at all dealerships, so I had to take the car in that condition. Before taking it, I spoke with the manager and GM to ask them to give me a car until they fixed mine because it wasn't right for me to drive the car like that. But they didn't offer me anything. I took it back to Bomnin Chevrolet Dadeland and they told me they were going to change the transmission and torque converter and conveniently they didn't have to change the valve.

Engine died when I was traveling at highway speed. Not warning lights no check engine lights. Was able to stear to the shoulder but vehicle woulnd't start or go into nuetral. Thankfully on a rural road so was able to get out of danger. Had this happened in a busy environment may not have been so forturnate. Dealer determined that 2 of the connecting rods bent and caused catostrophic engine damage. Since this happened I have read about 100's of other 6.2L gasoline engines having similar issues. This isn't a random occurance and Chevrolet has writted technical memos explaining the issue for thier dealers.

2023 silverado 1500 ZR2 19000 miles,motor shut off going down the freeway pulling my sxs at 70 miles an hour no warning nothing alarm nothing.my wife and i were scared to death trying to get off the freeway pulling a trailer and not knowing if the truck would make it.people around us beeping there horns with flipping us off,no warning.300$ to get my trailer toed back home.dealership tells me they don't have a loner but would give me a voucher.i have been trying to trade out of the truck after hearing about the truck problems 6.2 is a bad motor i new it was just a matter of time. now i am stuck.the scariest part was the timing could not have been worse coming off the freeway.how do i know even when it is fixed it will not happen again.then we could not get the truck in neutral to toe to dealership so they dragged the $80.000 truck on to the toe truck nice.

I was on Expressway with the cruise set on 72 Miles an hour I heard a loud clunk the engine, of course shut off I go down to the gearshift in the console. It said neutral so close it over to the side of the road got stopped as soon as our momentum stopped and we are completely at a standstill the truck put itself in park. I then tried to restart it and it wouldn’t do anything. I contacted OnStar state in my situation and after multiple conversations with them, I disconnected the phone call and contacted my own towing service because we were 51 miles from our home and they would not tell the people there unless I paid for over half of it. They would only tow it to the nearest dealer. We have been a free customer since 1997. We or a family owned Electrical contacting business. My truck is my office. I’m in 90% of my day. I elected to take it to the dealer where we purchased it, and we purchased a good portion of our vehicles over the years and helps that it would be repaired in a timely manner.

I was in stop and go traffic, the truck engine turned off I could not get it to crank. I was stuck in the middle of a busy road for at least an hour until the tow truck driver got there. Since the truck has electric shifting for the transmission, I could not get the truck into neutral to at-least push it to a safe place. I was informed by the dealership that there is no neutral override unless the vehicle is running. The shifting and fuel system “fuel module” failure is a know problem from GM and need to be recalled. If this would have happened on the interstate I don’t think the outcome would be great. The truck is a little over 1 year old and has under 15,000 miles. Very dangerous situation.
