2024 Chevrolet Silverado 1500 POWER TRAIN,ENGINE

Engine safety concern. Grinding and clunking while engine is running and gets worse under load or when accelerating. Have taken into dealer for service over 6 times. Recall service was performed and their fix was to change to a thicker oil but all that caused was worse fuel economy, more expensive oil changes, and the noises have become worse. Going back to dealer next week for another attempt. Have requested lemon replacement with GM but they are denying any issue.

The coolant control valve and the transmission control module are having to be replaced on thousands of Silverado 1500s from 2022 to 2025. Both parts have been updated, but there is no recall and many people are being left stranded due to this. Mine has not currently failed, but I am older and really don’t want to get stranded due to a known issue. Why wouldn’t they have been forced to do a recall General Motors should be replacing these as a preemptive precaution.

Component/System Failed: Power Train – specifically, the #6 lifter failed and is available for inspection upon request. Safety Risk: The failure caused noticeable engine misfiring, loss of power, and abnormal ticking sounds, which could potentially lead to engine stalling while driving. This creates a serious safety risk, especially during highway driving or merging situations. Confirmation of Problem: The issue was confirmed by a certified GM dealership technician, who diagnosed the failure of the #6 lifter. They advised that the lifter and potentially the camshaft need replacement. Inspection: The vehicle has been inspected by the dealership service department. No inspection has been conducted by police or insurance at this time. Warning Signs: Prior to failure, there were no warning lamps. However, the vehicle began exhibiting a noticeable ticking noise followed by rough idling and reduced performance approximately 71,000 miles.

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.

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.

I purchased a new 2024 Chevrolet Silverado 1500 4wd in May 2024 from a Chevrolet Dealer in East Tennessee, after having the truck for 5 months, it started experiencing a transmission "shutter / vibration" at higher speeds, it has also experienced a transmission "hard downshift" at times... a month later at only 4914 miles, it was dropped off at the chevrolet dealership here in my home state of Alabama for its first oil change and for them to check what is going on with the transmission, after the truck being there for 3 weeks, we were told that the transmission needed to come out for repairs, we advised the dealership and several GM representatives that we wanted a brand new transmission put in the truck that is brand new to start with, GM has refused and stated that they were going just rebuild the transmission.... we told them "No" and that we had bought a brand new truck, therefore it should have a new transmission, not a rebuilt one in a brand new truck with less than 5000 miles on it.... the truck has been out of our possession starting into its 3rd month being gone for repairs, not only is this a huge inconvenience for us, but its also a huge safety issue because we do occasionally pull trailers with this truck... General Motors has flat refused any help to our satisfaction with this transmission issue and has just pretty just blown us off and told us "No" when we have approached them with any kind of remedies for this situation, its pretty bad when a company that has taken a government bailout a few years ago, hasnt learned anything from their past mistakes and now think theyre untouchable.... it also pretty bad when you spend in excess of $60,000 for a pickup truck that you dont even have in your possession because of defective manufacturing.... yes, it is a safety issue even more because my family is sometimes using this truck and may not always react the same way that I would if something happened going down the road.... it needs a recall on these trucks

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.

Blown transmission valve body at 8000 total miles. Truck went into limp mode and will not reverse. Can not be safely driven. Has been sitting at dealership for 2 months now waiting for parts from GM. National backorder no ETA.
