2024 Chevrolet Silverado 1500 acceleration problems

VEHICLE SPEED CONTROL

Vehicle suddenly stalls and reduces speed at different times with no warning. At first it would show that message after car washes or rainy days but now randomly it’ll reduce speed in unexpected moments causing safety concerns. It reduces speed, stalls, drives forcefully, and shows a “reduced acceleration drive with care”. Sudden stalls have become a danger to my family and myself as we depend on this car to get to and from on a daily basis. Dealership states it’s the TCM but not covered under warranty. But the vehicle is new how is it that it already has defects

On [XXX], I was going to Atlanta, the truck started hesitating harshly while I was passing another driver on a two lane road. The truck wouldn’t accelerate and the paddle seemed to be stuck, I had to pull off the road to avoid a head on collision. On the 30th of May, I took the truck to Allen Turner in Pensacola, Florida where I purchased it and reported the issue, the service department was closed and they sent me next door to a Chevrolet Dealership, which was also closed. On today [XXX], I took the truck out for a test drive, and I had the same incident happen, but this time I pulled into a gas station and shutdown the truck. Once I turned the truck back on, the check engine light came on. I didn’t think I would make it back home, because the truck didn’t accelerate correctly, and when I pressed the gas pedal it didn’t accelerate and was making different noises. The pedal seemed to be stuck, with no acceleration. I recorded a little bit with my phone while trying to drive, but it’s not the best.

For the first time I purchased a brand new vehicle off a dealership lot…What a mistake. While the dealership itself was an awful experience I thought it was worth it for a Chevy Silverado. After all my previous one was so reliable. WRONG. The first issue I found was I was unable to shift into reverse to back out of the driveway of a fire station I volunteer at. After driving forward a couple times and shutting the vehicle off and shifting multiple times I had to be towed out in reverse. I was able to drive home but the transmissions slipped once and the vehicle slowed abruptly. The check engine light was now on. I dropped the vehicle off at the dealership over the weekend and on Monday they called and informed me the 2024 Silverado misfired once and nothing was wrong with the transmission. There was nothing they could do. About two months later I was driving to work as a career firefighter/paramedic when my vehicles check engine light came on and a message informed me that I was in “reduced acceleration mode”. I slowly and carefully made my way to work and brought the truck to the dealership after my shift. The check engine light was now on again. They informed me later that day that I had a faulty valve body in my transmission. They “unfortunately” could not give me a completion date on my repair as they had no ETA for the replacement part. It appears the part is in high demand. This makes sense as a quick google search shows this is a widely known issue with the 10 speed transmission. So far I have been unable to get a rental vehicle between the dealership and GM. Aside from my house my 2024 Silverado is the largest purchase of my life. And at 15,000 miles I am without it for the foreseeable future. As a first responder the communities I serve depend on me to respond from home at any hour. My family and I are living in a DIY renovation while also starting a farm business. I need a dependable vehicle and regret spending $53,000 on a new vehicle. I have more to say.

On 7 or 8 occasions while navigating parking lots/driveway turnaround, i bumped the resume switch on the steering wheel and the truck took off accelerating rapidly from 2-4 mph speed until I disengaged with the brake. Someone with slower reactions or unaware of what is going on is going to get hurt by this. I believe it's tied to collision avoidance system and the adaptive cruise control mode. This system will allow cruise to stay engaged even as it slows you to a halt in, e.g. a rush hour slowdown, but if it slows you to some speed just greater than zero, and the traffic ahead speeds up, it will speed back up to the cruise setting. Similarly, when cruise is disengaged by brake action, but there is still a stored value in cruise control, if you accidentally hit resume at slow speeds the logic is treating it like a traffic situation. So the old 20 or 25mph minimum engagement speed no longer applies. As for why I inadvertently hit resume, it has to do with the raised momentary rocker switch at the 9 oclock position on the steering wheel. If you make a turn with your palm against steering wheel. For example, on a left turn, if the wheel is turning counterclockwise and your left palm is in the 9 o'clock position, it can rub against the raised cruise control rocker triggering the resume function, and off she will go! A flush or recessed button/switch would have been a better choice here. At this point, a software change would be the best solution to ignore the resume function below a certain speed.

My truck had a check engine light come on for the transmission 2 months ago and then it went off before it was serviced. They said they couldn’t do anything since the light went off. Then last week I didn’t have reverse and it wouldn’t shift into gear. A week after it had been in the shop they told me the transmission valve body needs to be replaced. Expected date for parts to arrive is 3-10.

WHILE USING CRUISE CONTROL ON FREEWAY AT APPROX 70 MPH WHEN HEADED UP HILL AND THE VEHICLE REACHES APPROX. 2500-3k TACH, THE CRUISE WILL DISENGAGE AND SPEED WILL DROP IMMEDIATELY WITH NO WARNING. DEALER SAYS MANUAL STATES ONE MAY HAVE TO USE THROTTLE TO MAINTAIN SPEED BUT DOES NOT MENTION CRUISE DROPPING OFF. THIS IS AN EXTREME SAFETY RISK WHEN A VEHICLE IS BEHIND YOU ACCELERATING ON THE SAME INCLINE AND YOU SUDDENLY DROP SPEED WITH NO BRAKE LIGHTS ILLUMINATING.

The cluster that makes my dash gauges visible has failed and malfunctioning. The safety concern is that I cannot see my speed, my tire pressure, mileage, and I will not be able to see if there are other issues wrong with my vehicle since the entire dash gauges are not visible. The system is not resetting while driving and I lose power when it does that. I have to guess when to put gas or put the risk of myself and other drivers of my vehicle stalling out in the middle of a highway. The issue has been inspected by a dealer during an oil change and they even left a note for me that they were unable to reset my oil mileage because the system is not working. The dealership performed a system test and performed an update and they confirmed that did not fix the cluster issue. There were no warnings before this happened.
