Chevrolet Colorado sudden acceleration problems

Filed Mar 30, 2026 · Transmission · TN

Torque converter shutter makes vehicle lunge forward while driving. Feels like something pushes you from behind. On a wet road and especially in a curve this could cause rear wheels to slide.

Vehicle accelerated on its own at a stop and then at highway speeds. Took it to dealership who experienced the same thing and confirmed the issue and could not find the reason why.

I just bought this truck. While driving it on the first day we were in stop and go traffic and I pressed the throttle and nothing happened, when I pressed it further it all of a sudden squealed tires and jumped forward causing me to almost rear end the car in front.

The truck has a hard downshift and when stopping and starting again at a stop sign it will lunge forward sometimes.Also,when holding speed at 50-60 mph you can feel a slight shutter like the truck is not running correctly.The dealer flushed the transmission when I purchased the truck but the issue continued so I made an appointment with the service department on march 3,2023.They took the truck on a road test and did notice the hard downshift and noted that this is a normal characteristic of this transmission(this is not normal and is unsafe)and will not offer to repair it.It is now the end of July 2023 and the issue continues and no one seems to want to do anything about it.I am going to take it back again but I am probably going to get the same answer

The transmission surges causing the truck to lunge forward when starting from a stop. The key will not turn completely off allowing the key to be removed. Both events occur occasionally so if the dealer says it did not happen to them then there is nothing they can do. Both things are being reported on the internet by numerous people. Both things are safety hazards.

I was turning into an apartment complex parking lot in noted vehicle when the vehicle suddenly accelerated sending me into the side of the apartment building. I was in the process of applying the brake when this occurred. There was no time to react or avoid the side of building and I incurred damage to both my vehicle and the side of the building.

The transmission is extremely slow to downshift. As you continue to push the gas pedal, it will finally downshift, sometimes two gears, and suddenly accelerate. When on cruise control, you loose about four MPH before it finally downshifts, again sometimes downshifting two gears. In traffic, the car behind you doesn't anticipate the loss of speed and then you suddenly accelerate. It happens at all speeds, but is particularly unsafe at low speeds with the sudden acceleration. This is probably a software problem as the transmission shifts much more normally if you put it in 'tow/haul' mode. The dealer says this is 'normal' and gm calls it ' torque management '. It is especially unsafe in slick conditions or rainy roads. Btw, I have a 2017 impala with the same six speed and v-6, and it does not exhibit this reluctance to downshift. Thank you.

The vehicle was going down hill on a very busy highway when we tapped the brakes to slow down and the brakes went to the floor and we skid about 300 yards before being able to get the truck to come to a stop. We kept tapping brakes trying to get them to grab and stop us luckily, the car a head of us turned right at the light so we did not crash into them. Then when it did stop the RPM started reeving up and the truck lunged forward then the RPM went down. We were very lucky we did not go through the intersection and wreck.

On 6/6/16 I started having the trouble. After backing up and putting the truck in gear, the truck would surge forward without touching the gas pedal. This also occurred on 6/11/16, 6/17/16 and 6/23/16. On 6/23/16 I was at surdykes port 20 marina at the lake of the ozarks. After backing out of the parking space I put it in gear. This time it was much more than a surge. It literally shot forward and even the brakes didn't help because within 3-4 seconds my truck and I were in the lake. Finally got the window to break so I could escape. Just before I went in the lake the truck struck an old golf cart and jet ski trailer that were parked there and took them into the lake also.
