Filed Oct 22, 2026 · Acceleration, Driver assistance · IA

I pulled off the interstate after traveling 70mph with cruise control on. I then pulled into the Walmart parking lot and started to enter a parking spot rolling at 5mph and accidentally brushed the resume cruise control and the truck shot me forward and I came within inches of the car ahead of me because the truck suddenly started accelerating.

In reference to 2024 Chevrolet pickup, 6.2L engine, 10 speed transmission. The vehicle is available for inspection upon request. I believe the transmission is going into "partial lock-up" at full/highway speed. When traveling on highway with cruise control engaged, the vehicle suddenly acts as though the brakes are being strongly applied, slowing the vehicle at a very rapid rate, down as low as about 40 MPH. The vehicle slows quickly enough that the driver and passengers are thrown forward to the extent allowed by the seat/safety belts. The issue terminates itself at various times. The vehicle has been inspected by GM mechanics several times, but they cannot find the problem. There were no warning lamps, messages, service engine lights, etc. This has occurred on at least five (5) different occasions. The first occasion was at approximately 7000 odometer miles. The vehicle now has 25,100 miles. All incidents have been reported to GM dealership mechanics.

After taking in to dealer for recall diagnostics and higher viscosity oil change a couple months later. Heard a noise while driving on interstate, lost cruise control, stability system, engine light came on with a ECS. Kept driving on the interstate until we got to a red light and the engine died. Cranked starter but hard to start and ran rough and died multiple times. Feathered throttle to get over 1K RPMs to get it off the street. Towed to nearest Chev dealer. P300 code. Tore engine down. Here is what dealer documented: CUSTOMER STATES CHECK ENGINE LIGHT IS ON WITH SERVICE TRACTION & SERVICE ESC MESSAGES. ENGINE IS RUNNING ROUGH AND WILL STALL. TOW IN. Valve Spring Replacement - Replacing the faulty valve spring on the cylinder 7 exhaust side is necessary as it is causing the exhaust valve to remain stuckopen, leading to engine misfire and over 80% leakage in that cylinder. This service can help restore proper engine compression and improve engine performance. Op.1 CEL -CEL: Customer states 1. replaced the exhaust valve spring and valve spring seal. reinstalled components with new seals and cleared dtcs. started engine and verified the engine starts and runs but having multiple cylinder misfires. reset engine fuel trims and brought engine to operating temperature and let it run for some time. other cylinder misfires went away but still found a dead misfire on cylinder 7. removed and swapped spark plugs with no change. noted the spark plugs have some exhaust build up on the tip due to the faulty exhaust valve spring. performed a static compression test and found the compression to be 175 psi and a running compression test with a smooth build up to 125 psi. checked spark and spark was good. tested the injector system using the AFIT test and found the test to pass indicating no faults with the fuel injectors. performed a cylinder leak down test and found no cylinder leakage coming from cylinder 7. put engine back together and cleared dtcs. reset the throttle

These incidents are unrelated: 1) Multiple times the Adaptive cruise brakes when no object is in front of the vehicle. Almost causing the vehicle behind to rear end you. 2) Engine failure while driving.

6.2 L engine around 7500 miles engine light came on, it was slow to startup, would shutter during idel. Driving home on the highway the truck turned off cruise control and front impact warning then it came back on about 5 miles down the road. At the same time the truck was shaking and shuttering. Took it into the shop the next day and so far is having at least one maybe 2 cylinders misfiring. Also, since I bought it the axle locks keep saying to service them, take the truck to the dealership and they can't find anything wrong with them. The only way to get the indicator to stop dinging incessantly is to active the axle locks and deactivate them and that will make it stop dinging for about a week.

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.

I was driving on [XXX] leaving from Onawa, IA. Up to this point I had not issue or notifications about my vehicle. While driving North bout and having the adaptive cruise control set at 80 MPH, I was in the left lane passing 3 semis in the right lane. After passing the first one, the first semi merged to the left lane following. I was approximately 1/2 passed the next semi when all the sudden my cruise started to slow down. It went from 80 to 78 back to 80, then 80 back to 77 to 80. Suddenly and with no warning the engine completely shut down and I went from 80 - 0 is approx. 100 feet. The semi behind me sounded their horn loudly as they almost hit my rear end before merging over. I had no time to go over to the right shoulder and had to go to the left where the vehicle would not move. I could not move the vehicle off the shoulder as it would not shift to natural. Law enforcement was notified as the safety of the vehicle on the left side of the interstate caused safety issues.

Driving on interstate 85 on cruise control when I herd the motor RPM start to climb so I tapped the break and that’s when the truck shut itself off and put itself in neutral causing me to have to coast over to shoulder of the road. Message on the dash said push start button to start again. There were no check engine lights, no overheating temperature lights. No codes at all. The truck is a 2024 with 62,000 miles and all oil changes on time. Upon checking online , this has happened to other vehicle owners as well. Apparently the Chevy Silverado with the 6.2 liter engine has problems with push rods and bearings. Some have replaced multiple engines. Chevy wants me to pay for new engine.

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.
