The component that failed is the camshaft position actuator. My check engine light came on. Had my vvt solenoids replaced and the mechanic told me the actuator needs replacing. GM has issued a special bulletin to fix this part for the same year make and model as my truck but my vin doesn’t meet the criteria. I have only owned this vehicle for 8 months.
Unknown. When my truck reaches a certain speed it is jumping or missing, it feels like a brake is sticking but I’m told it is a problem with my transmission, torque converter, going bad. It is getting worse. It cuts the power down on the vehicle. If I can go faster than 60 it doesn’t do it.
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 oil cooler lines are rusting and leaking. Seems to be a common issue going back 9 years since they started making these new Colorados from information I found online. Totally unacceptable for a truck to that is 4 years old to be rotting out. One of the lines is a nightmare to replace because of where it is inserted into the motor. Mechanic had to remove the front differential, axle, ac compressor, drive shaft, fuse box, and intake to replace a 60$ oil line
