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.

COMPLAINT # 11630574 Transmission Shudder, took to dealership on 09/28/2023 had transmission flushed and changed fluid to new style transmission fluid, per GM under warranty. I was told that if it needed done again that i would have to pay to have it done and would cost approximately $400- $500. On 12/13/2024 the truck is shuddering again at 48,700 miles.
There is a known issue with my truck, where the Transmission will all of a sudden lock up and then it shutters. The truck shakes violently and happens randomly. There is no rhyme or reason why this happens. Of course I'm barely over my warranty and Chevy in Austin states that it will be 3-5 days before they can review my truck. They won't provide a rental car or any help with a rental, so I'm expected to not have a car or figure out something myself to even have my truck looked at. My friend has GMC Canyon (same transmission) and had to have a level two mechanic replace his fluids. There are no warning lights or anything, this is a constant thing that is getting worse. There is a lawsuit in Canada for this issue that Chevy has known about and they haven't done anything about it.
Torque converter shudder. Had dealer do the recommended flush which cost $800 and still has same issue.
The contact owns a 2020 Chevrolet Colorado. The contact stated that while accelerating, the vehicle vibrated and shook abnormally, as if driven over ripples on the roadway. No warning lights were illuminated. The vehicle was taken to the dealer, and the tires were balanced. The contact picked up the vehicle and stated that the failure persisted. The vehicle was taken back to the dealer, where it was diagnosed that the transmission oil failed to heat up as intended, and condensation had built up in the transmission. The dealer added Mobil 1 transmission oil to heat up the oil and remove the condensation. The contact was informed by the dealer that the vehicle needed to be driven between 200 and 400 miles to remove the condensation. The manufacturer was made aware of the failure and filed a

The Automatic 8-Speed Transmission completely deteriorated after 4 years/64,000 miles exactly after the Power Train Warranty. No warning lights or signals identified me of the problem, only a noticeable shuddering when driving at highway speeds. This vehicle is currently at the dealership where they have confirmed I will need a new transmission to replace the faulty original manufacturer's transmission. My safety and others' safety is/was affected by a faulty piece of equipment that was destroyed with regular use. This could potentially lead to my vehicle being unable to shift up/down during traffic leading to an injury or worse.

While driving the radio will go suddenly to full blast without reason. After about 2-3 seconds it will return to normal volume
IGNITION LOCKED UP. This situation is the same as another complaint posted earlier this year by another owner. Ignition key will not turn in the igntion switch. Tried all the internet fixes. Turning steering wheel, bumping transmission lever, tried spare key, etc. Nothing worked. $225 to tow to the dealer. Still waiting to hear from back from dealer.
While starting to drive the vehicle a gushing water sound is coming from behing the dash.
While beginning to accelerate after starting the vehicle, I noticeable sound that is best described as 'water rushing' is heard from behind the passenger-side dash area. After conducting some research I have narrowed it down to the issue of air trapped in the coolant system. Issue is isolated to the area of the heater core. Have also seen mentions of service bulletins where, if the vehicle is under warranty, it can be brought in and the tank can be drained and refilled properly.

Within the last 2 months, I have had momentary steering problems at low speed. They continue to become worse with time, no longer safe to drive. Dealer has vehicle now and informs me that it will cost $3000 for a known/existing corrosion of electrical connections in the power steering assembly. Via the internet, the steering gear torque sensor cover assembly needs to be replaced. Because this cover assembly has leaked, the wiring harness also has to be replaced. 7 hours of labor, front end alignment, etc! The loss of power steering in a turn has nearly caused several accidents till I got it home. Dealer confirms what I experienced in test drive, internet has many examples of same problem and solution. There are no warnings of impending loss of control, one minute everything is fine, the ne

engine 1 complaint shown
Check engine light appeared when starting vehicle. Code read by local auto parts store. Thermostat failed at less than 50k miles, causing fan to run constantly and for an extended period time after turning engine off, despite outside temperature. Causes potential for overheating due to not reading temperature. Thermostats are rated to last 100k miles. Is not covered under Chevrolet's 5 years/100k miles powertrain warranty. Upon research, this has been an extremely common issue for Colorado trucks for many years and has not been addressed by Chevrolet. Many blogs are available online. This vehicle was a certified vehicle bought just over 1 years ago and would not be fixed by any warranty according to the dealership purchased from (Bob Fisher).

The component that’s failing on my truck is the Apple car play and a check engine light (CODE P0024) which indicates Exhaust Camshaft Position, Bank 2. My safety and others safety is put at risk while having these issues: 1.) The Apple Car Play, having to take my focus off of driving to try and unplug my phone and plug it back in to HOPEFULLY fix the issue of using the navigation or phone calls while I’m driving during long road trips is extremely dangerous for myself, my loved ones and others on the road around me. 2.) This error code is extremely unsettling to experience while 500 miles away from home and has caused an incredible amount of stress on multiple occasions. The light constantly turns on and off, leaving me completely clueless as to if I’m going to be left stranded on the si
