2019 Chevrolet Colorado: sudden loss of power

Filed Nov 3, 2026 · Transmission · LA

Drive train shudders intermittently seams like a program issue. Chevy trying to achieve higher MPG creating a driving issue. Loss of power on the highway. Makes me wonder about total failure at highway speeds and getting hit from behind. Chevy knows about this and makes the owner eat the cost and refuses to address the issue. I truly believe Chevy knows how to fix it but refuses and refuses to release accurate information.

The contact's husband owned a 2019 Chevrolet Colorado. The contact stated that while her husband was driving and she was a passenger, their vehicle shuddered and then lost power at approximately 55 MPH. The vehicle was guided to the side of the road, where the contact and her husband noticed smoke emerging near the gear shift. For safety reasons, they both exited the vehicle and moved away from it. The contact then observed flames appearing between the driver's side of the cab and the bed of the vehicle, which quickly burst into flames. Another motorist attempted to extinguish the fire with an extinguisher, but it ran out before the fire could be contained, and the vehicle became fully engulfed in flames. Although the police were called, a formal report was not filed. The fire department arrived and extinguished the fire. The manufacturer was not notified of the failure. The failure mileage was approximately 41,000.

While driving the vehicle lost power, would not go over 15 mph. There was a loud rattling noise from the engine. Check engine light came on. loss of power and speed prevented me from keeping up with traffic. Had vehicle towed to Chevrolet Dealership was told high pressure fuel pump mounting bolts had broken and fuel pump was loose. Dealer replace fuel pump and one fuel pipe (part #12627128). I paid full price repair ($ 1,775.21) and contacted Chevrolet to see if they would offer any assistance I was under the power-train mileage but over on time. They offered and I accepted 50% of the repair cost but no towing. After some research I discovered there was a recall (18V358000) for an erlier model for a similar problem . The recall was for the fuel pump separating from the base which could damage the fuel line and create a fire hazard. In my case the entire pump came loose which leads to the same result as the pump separating from the mounting plate.

This truck has roughly 41000 miles on it. As I was driving home from work on [XXX], I heard a faint noise and then my truck just lost power and died on the freeway. There were no engine warning lights on and did not want to restart and stay running. After a few times of starting and dying the message on the dash said keep driving engine is in regen. This is a diesel truck and the newer ones have a regeneration that is done with DEF. I was unable to get it off onto the exit, but did get it off the roadway. The vehicle was towed into the shop on February 3rd, 2024. The shop had to order parts and said that it was just a faulty part. I received the truck back on March 14th. I drove it home from the shop and to work for two days putting roughly 100 miles on the truck. On my way home on [XXX] , the truck died again with no warning at all. Same symptoms, just no power and no warning. The truck was towed back to the shop where it still sits today. The problem is there is an issue with this thing dying without any warning at all. The dealer and Chevrolet techs have been unsuccessful in finding the problem. It has been almost 6 months in the shop with literally no idea of what is wrong. I feel this is a serious safety issue that could leave people or families stranded without any warning or idea of how to repair. I feel this should be investigated and brought to someone's attention. I have contacted Chevrolet, but unfortunately they have left everything up to the dealership. The dealer is Auburn Chevrolet in Auburn, WA.

February 2023 my son was driving 40 mph (approx) and the power steering became disabled. We took the truck to Landers McLarty Chevrolet. They never mentioned a known recall for this issue on previous year models. The Truck only had 27,000 miles but was out of warranty for the 3 years had expired in August. They gave an initial estimate and repair of $750. Picked up the vehicle and on the way home same thing happens again - lost power steering and then had warning lights on dash after it went out. Took it directly back to dealership. 3 attempts and 5 weeks later including +-$5K cost for 3 different repairs - issue seemed to be resolved. The issue returned today as my son was driving 55 mph (approx) lost power steering in extremely heavy traffic. Knowing what had happened before he was able to navigate to an exit without having an accident. There seems to be a known issue with the power steering on the Colorado. There was a previous recall on earlier year. I had made complaints and spoke to GM multiple times and they said it needed to go through the dealer. GM never mentioned any recall issue with power steering on previous years and offered no direction on possible issues as the truck sat for weeks on end with no resolution.

The stabitrac system malfunctioned and went into low power mode while on the highway almost in an accident because of speed loss. The button to turn it off did nothing. Still unsure what caused this to malfunction but needs to be a way to override to maintain speed without power loss

As I went around a turn (low speed), the truck lost power steering for about a half of a second. It came back online right away, but caused me to take the turn poorly. At the same time, the engine shut down and all of the lights on the dash went out. I stopped the vehicle, put it in park and restarted the vehicle. Everything then worked as if nothing was wrong. There are not any warning lights. It was as if someone simply turned off the ignition for a minute.
