2024 Chevrolet Silverado 1500

My Silverado has what seems to be a known issue with recent model Silverados which is a broken/blown valve body at the transmission. The week of the failure, my truck began having rough shifting from first to second gear first thing in the morning, but would be fine after that. Two days later this progressed to all of the gears and nearly stranded me and my kids on the interstate due to not being able to maintain speed. I got the truck to the dealership where they looked up diagnosis code and told me it was the valve body and it would require replacing. Unfortunately, the part is on national backorder with unknown delivery time. Looking online, it seems this is a known issue and parts seems to be months (6+) behind. I am stuck paying for a rental car that GM says I will get reimbursed for, but we will see. To complete the questions above, I did not notice any warning lights or notices until it failed.

When in Normal Drive mode, an unexpected or accidental bump of the Transmission T-Handle shifter between the seats towards rear of vehicle while at a stop sign or parking lot, etc. will "Lock The Transmission in Low Gear 1 out of 10 available gears". If one pulls out into traffic without noticing this event, the engine will approach redline without shifting into the next gear until the situation is acknowledged and the T-Handle is one again pulled back to reset it into automatic drive mode. This is frustrating and potentially dangerous if the situation is not recognized quickly. I suppose engine damage could be at risk. There is "No save the engine by automatically selecting the next gear if this condition happens. There is also no lockout requiring the T-Handle Shift Button on the side requiring to be pushed to acknowledge the desire to set this mode". I tested similar settings on Honda Pilot and it DOES UPSHIFT even if in this manual mode to protect engine and occupants from this difficult situation. I personally will no longer allow any others to drive my truck until this situation is remedied. It appears to be dangerous to me and my truck for those who have no idea this can occur. Please try it for yourself. Vehicle must be similar to 2024 Silverado High Country w T-Handle shifter between the seats. My hope is an over the air update can remedy this situation.

Pulled into parking lot and went into a store. Upon leaving I noticed the vehicle would not back up when placed into reverse gear. The engine would rev but, no movement. I pushed the vehicle backwards and then restarted it. The vehicle would move forward. I stopped and attempted to try the reverse gear a few more times with no luck. As I started driving on the main roadway toward the GM dealership, the vehicle upshifted once and then displayed a warning along with e check engine light. Once at the dealership, they scanned the vehicle and confirmed a transmission issue. The vehicle never showed any symptoms prior to the failure.

I got my new 2024 Chevy Silverado 2.7l turbomax custom 6 months ago. It shifts weird the first few times from a cold start. I have asked the salesman and he said yeah you have to let the truck warm up for 5 min or so. But even in doing so it still happens, worse the colder out it is. Yesterday I went to grab some food and went to take off onto the main road and when it tried to shift from first to second it felt like the transmission just stopped working for a few seconds then hit 2nd gear hard. I was told this was because the truck needs to get used to the way I drive it. Which I now have close to 4,000 miles on it and it still happens almost every time I shut the truck off and it cools down to ambient temperature. I know this is not normal, and a big safety concern because when I do go to pull out and this happens it feels like a total loss of power and does not take off like it should. I have yet to bring it into the dealership. But I have called about the issue and was told this is normal and would go away. Which it has not. So I am going to make a appointment to get it in the shop. I have also read that many others are having this same exact issue. In which case some people are saying they told them the same thing “that it’s normal”, I have heard others say they will change transmission fluid because the fluid they used is to thick, and have heard of others who had to have them change out the control module for the transmission and or reset it. I am just worried that I’m going to pull out on day and have this happen and get hit from the rear because I don’t have the power I should have to take off properly. Not to mention I should not have to let my car idle for 5-10 min before I can drive it. That’s a huge waste of gas, and time, plus having your direct injection idle makes a ton of carbon build up in the engine. I am not a certified technician but I have been working on my own vehicles for over 20 years now. So a brand new truck should not be doing this.

I had a engine failure in my 2024 Chevy Silverrado Trail Boss1500. I had just exited off the highway and came to a complete stop at the stoplight. When the light turned green, I hit the gas pedal and I did not move. I looked down at my gear shifter and noticed the truck was in park (I did not shift the truck into park). I tried to put the truck into drive and realized the engine was not running. I tried starting the truck and it would not start. The truck would crank, but would not start up. I tried this several times with no luck getting truck started. I even tried to put the truck in neutral to get the truck out of the middle of the road and could not get it neutral to move it. I called chevy roadside to tow it to the dealer. The dealership called me on tuesday and said the engine had blown because of a bearing failure and engine needs replaced. Also, they have not let me know approx time I will get my truck back. They claim there's a shortages of engines on the 6.2 liter engine.

Truck has 7000 miles defective valve body failure would not go into reverse and in limp went to dealership and diagnosis is needs valve body replacement with parts on back order with no eta. They said it could be 3-5 months. This is a national issue I’m on multiple social media sites for Chevy trail boss and there is too many to count and it’s been happening since 2021. GM has been no help no loaners and you have to pay for a rental for 3-5 months and pay your truck payments and hopes you are reimbursed at the end. They just recalled the 2021-2022 same 10spd transmissions they are selling Trucks knowing these issues exist also the lifter issues with total engine failures at 10000 miles. The transmission lock up at high speeds.

While driving my vehicle on the highway I was exiting when I looked down at the instrument panel it stated a message along the lines of shifting to neutral and to press the ignition to restart engine. I noticed the vehicle wasn’t accelerating when attempting so I slowed down and did what it instructed me to do. The engine then wouldn’t start, I was uneasy because cars were coming from behind at a decent speed because of morning traffic. I somehow managed to get it to crank and took it to the dealer right away. They stated it was from low voltage and were replacing the battery under warranty. I didn’t think that was the cause but gave them the benefit of the doubt. 2 weeks later while taking my family out, the same incident happened. I wasn’t able to get it to crank and had to get it towed to the dealer. They stated it was the engine because now the engine was making a loud sound when ignited. It is about to be 4 weeks without vehicle and no repair has been made due to no inventory on engines.

Was pulling out onto the road from sitting at a traffic light, vehicle was going less than 25mph when the engine made a clunk trying to shift and the check engine light came on. Computer software indicated “limp mode with reduced acceleration activated.” Vehicle wouldn’t accelerate above 35mph, had to drive on major highway to get to dealership. Truck is only used as commuter vehicle hasn’t towed anything. Dealership indicated valve body transmission failed with vehicle only have 9k miles on it. Part is on back order as it is being manufactured due to installed faulty part, problem has been going on in 2023/2024 Chevy and gmc trucks since January 2024 without a recall put in place. Problem is being fixed after the part fails and the truck fails to run at optimal valves. According to forums software update were installed versus recalls to the actually valve body part being. I was sold a truck in sept 2024 with a faulty installed part versus it being fixed before it was purchased. This caused me to be stranded 1500 miles away from my home and we were not made aware of the know valve body transmission issue. The information was covered up versus being disclosed.
