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.

Rear camera does not work 100% of the time, this has been happening for several weeks. It goes blue with no picture and a service camera message. Camera was reprogrammed by dealer on 12/16/19, camera again failed on 12/17/19 - same issue. Vehicle returned to dealer on 12/18/19 - camera was replaced, the morning of 12/19/19 - camera failed again. This happens when vehicle is placed in reverse and camera is supposed to activate. It also has appeared to happen as the temperatures have gotten lower here in the midwest. As vehicle warms up - camera function returns to normal.

Go to turn the key off and the ignition won't turn off all the way, have to restart the truck a couple of times to even get the key to turn off to get the key out, also go to start the truck and sometimes it won't move the iginition

I own a 2017 Chevy Colorado Z71 4X4. Once back on the highway after off-roading on the beach, while forward driving at roughly 50 mph I ran over a chopped piece of fire wood in the road. The piece of wood contacted the skid plate, which then collapsed the hollow skid plate bracket welded to the front cross section/axle of the chassis, which then flattened into the plastic power steering module(s) connected to the electric power steering (eps) rack. This caused immediate loss of power steering, loss of ABS vehicle control, loss of electrical charge from the alternator to the battery, loss of ability of the vehicle to show correct speed, random transmission shifting (into and out of gears, as well as throwing vehicle into neutral) as well as intermittent loss of all cabin electronics (including tachometer relaying speed and rpms, odometer, fuel gauge, battery voltage gauge, etc.). due to this being a road hazard incident, as well as poor manufacturer design/placement of a plastic electric power steering rack, I was forced to have the vehicle towed and file a claim with my insurance company. Repairs have been ongoing for 3 weeks and are still incomplete as the vehicle's computer cannot recognize the new oem part. Attached photos show damage with the skid plate removed. Mathematical measurements will prove the collapsible bracket, if flattened in a similar directional manner, will most definitely make contact with and impact the electric power steering rack. This plastic rack also includes other modules that impact the aforementioned performance issues. GM has failed to acknowledge my concern of design after multiple attempts and conact with their
