Received a P2138 Throttle/Pedal position sensor/switch "D"/"E" voltage correlation code while driving that caused "Reduced Power" and "stabilitrak" errors. The reduced power mode it went into made the truck unable to accelerate in a safe manner and made the truck "jump" wildly as it attempted to accelerate.

My son was driving the vehicle when it lost power and he had to maneauver to the side of the road putting himself and others in danger. The truck was not able to drive forward, but could only drive in reverse. There were no warning lights or other indications that the vehicle had a problem. I had it towed to a mechanic who said Chevy Colorados have problems with their transmissions and it would need to be replaced.

While traveling down the highway at 70-75 MPH a wrist pin failure occurred. This lead to a rod punching a hole in the bottom part of the engine, obviously I lost all engine power and had to coast to the side of the road in traffic. Looking online there are wrist pin studies conducted by Geen diesel engineering company that shows obvious manufacturing defect in gm wrist pins. Upon further research I have found that this is a common failure with the 2.8 liter diesels. I contacted gm they informed me that this is not a documented problem which has set me back about $14,000. I found out that I’m not alone from what I have found it seems to affect 2016-2017 models. I’ve seen failures occurring within 7000 miles.

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

Experience transmission shudder while driving vehicle. Could cause issue while passing other vehicles due to loss of power. The amount of money these newer vehicles are charging, transmission shifting should be flawless. Not sure if this is going to get worse and cause an accident. Could it jump gears while trying to come to a stop? This is ongoing and needs to be addressed and a remedy by the manufacturer soon.

While accelerating on the freeway from approximately 65mph, the stability control system engaged and took control of the acceleration of the vehicle. Roads were dry without ice, snow or rain. The stability control reduced power until the engine died even while pressing the accelerator to the floor. The engine would not restart for approximately 5 minutes. This occurred 3 times on different interstates on a trip. We were forced to carefully move to the right shoulder while our vehicle was slowing until the engine died. My wife and I were lucky we were not involved in a serious accident.

In cold temperatures that the northern states experience (around 4 degrees f) the truck will intermittently die in the middle of the road while driving. Complete power loss with no warning, which seems to happen at any time. When the weather is above 10f consistently it seems there are no issues. Extremely dangerous and can leave you suddenly without power while driving.

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
