Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My new chevy Colorado truck (10000 miles) has experienced vibration issued between 30-60 MPH. Typically it happens when in cruise control between 50-60 MPH and I transition from going downhill to uphill and the engine is starting to re-engage and accelerate to maintain speed. It feels like I am going over rumble strips and items in my glove box can be heard vibrating around. Apparently it is common enough that on the internet it is known as the chevy shake . I am worried about premature transmission failure. …”
NHTSA complaint #11407391, filed 2021-04, 10,000 miles“The vehicle is experiencing a shake and/or shudder during light throttle acceleration between 25 and 80 MPH steady state driving when transmission is not actively shifting gears. The condition is as if I were driving over rumble strips. Tsb 18-na-355 addresses this issue in 2017 - 2019 chevy Colorado pickup trucks with the 8 speed transmission. The 2020 model should be added as it does not appeared to be fixed at this time. I purchased this vehicle brand new from the factory with only 5 miles on it. The shudder issue has been persistent from the very first day I drove it.”
NHTSA complaint #11385950, filed 2020-12, 10 miles“Transmission shuttering mostly at interstate speeds but as slow as 35 mph. Under light to medium light pedal acceleration. Truck feels as if it's going over Road ripples. I'm disappointed to find out this is a common problem with Chevy 8-speed Transmissions. It happens every time I drive it. From time to time it'll shake the truck a little violently”
NHTSA complaint #11686682, filed 2025-09“The rear differential suddenly broke down on my way to take the freeway,making a very clicking loud noise of the rear wheel and Colorado was responding to the transmission do to a differential failure.and I noticed that oil was all over the road”
NHTSA complaint #11602044, filed 2024-07“Vehicle is experiencing a shake and/or shudder during light throttle acceleration between 25 and 80 MPH in a steady state of driving when the transmission is not actively shifting gears. The vehicle shudders as if I am driving on rumble strips. Tsb 18-na-355 shows same issue with 2017-2019 colorados, but should probably include 2020 models as the condition is identical to what my vehicle is experiencing.”
