2017 Chevrolet Colorado pickup with 58,000 miles. Check engine light came on. Scanner reading by a repair shop indicated a EVAP issue. I declined the $1200 repair estimate. I paid for diagnosis of problem $200. I repaired the system by "cleaning 2 filters at the beginning of the fuel tank ventilation system. The "primary filter and hose are located in a especially dusty area on the pickup truck and is prong to plugging if regularly driven on rural gravel roads. Nothing in the owner's manual indicates the service is required of this filter. FILTER SHOULD BE RELOCATED TO ENGINE BAY. Check engine light was reset and has not come back on. NOTE: This is part of the pollution equipment that stopped working properly before 10yr. or 100,00 miles.

This vehicle has had recurrent exhaust system problems that cause the check engine light to turn on and notices to appear on the dash display. At 11557 miles and 20 months of ownership the particulate matter sensor failed for the first time. This vehicle is currently on it's 5th particulate matter sensor and has required dealer attention for this same problem approximately every 1,000 miles since the first occurrence. The dealership stated that all they can do is keep replacing the part, with no idea whether the repair will even last between service intervals. At approximately 15,000 miles a notice appeared on the dash that said 'cleaning exhaust filter must continue driving'. It did not turn off in the extra 2 hours that I continued driving. The check engine light eventually came on, along with a message that said 'engine power is reduced'. I believe that these repetitive exhaust system problems are a significant safety issue. Not only do they require a driver to sometimes drive much more than intended, which increases the risk of an accident or other problems, but they could result in breakdown and stranding. Currently, there are 15,250 miles on the odometer and according to dealer service records this truck has spent 79 days at the dealership for warranty repairs. Gm has agreed to extend the warranty to cover future exhaust system repairs but has denied a request for repurchase or replacement. It seems unreasonable that gm is not willing to accept responsibility for an exhaust system that does not function properly and can't seem to be fixed. I obviously did not sign up for this when I purchased a new vehicle. Please see dealer service records (attached).

Twice now my 2017 w/~41000 miles has gone into instant, no warning or grace period, but an instant drop to a forced 10 MPH in the middle of traffic, this last time on a highway with no shoulders during rush hour. The three codes thrown the first time (I don't have the codes from the second time but the dealer is ordering a new ECM based on the u0401 code): rc (radio controls): b1325 - control module power circuit - low voltage ebcm (electronic brake control module): u0401 - invalid data received from engine control module - invalid data ECM (engine control module) p200c diesel particulate filter (dpf) high temperature along with the codes the check engine, stablitrak, and traction control lights came on - however braking was not affected! Regardless, this programmed 'limp' mode is insanely reckless with total disregard for the safety and welfare of the vehicle occupants, there is absolutely no safe place or reason to deliberately cripple a vehicle while in traffic! Some european manufactures at least give you a warning with several engine restarts to let you drive normally to safety and then a dealer for service ' but apparently emissions laws in the us take precedence over human life. Limp mode can be disabled for emergency vehicles but the dealership told me it was illegal for them to do it for me. The dealership has been great but limited to what they can do because of gm requirements. They are currently looking into the problem and has ordered a new ECM as a second phase in troubleshooting the issue (first was reprogramming the ECM) however there is still no excuse for forcing a vehicle into limp-mode while in use - I have lost all faith in this vehicle and gm and cannot trust it for my own yet families safe use.

I got a check engine light while and engine goes into reduced power mode. You can't drive in reduced power mode! I have to clear it to move the truck. I did a scan which showed a p2138 code. But its just in memory and the dealer wont fix it unless its an active code but can't drive to the dealer in reduced power mode. Its a catch 22

When automatic transmission downshifts into 1st gear coming to a stop, it lunges forward. If when nosing into a parking space with any kind of pole or vehicle directly in front of my truck, not leaving enough space my truck would hit whatever. When driving slowly with my 8 speed automatic transmission sometimes it rattles as if I am on a rumble strip and sometimes it just clunks or thuds. This and other shift issues make me even more hyper vigilant when driving. 6 months after I purchased my brand new 2017 colorado, during a spell of negative degree weather I lost the following: my cruise control, traction control, four-wheel drive; my engine light came, oil light all lights came on and my radio stopped working. I was told by my chevy dealer that this was normal in cold weather. Next, I was informed it must be because I washed my vehicle the day before. This went on for a few months, with me showing them videos and them telling me they could not duplicate the issue. October of 2018 they replaced my radio because evidently the radio had a bulletin that showed all of the things I had complained about. I want to say this happened in excess of 10 or more times. Driving to my mothers one evening in the dark my dash lights were not dimming correctly and then went out. As I got to a four way intersection with cars coming they came on so brightly I almost got in an accident which prompted me to make an appointment and I wasn't willing to hear silly excuses.
