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 contact owns a 2019 Chevrolet Colorado. The contact's husband stated that while driving 20 MPH, while attempting to turn into a parking lot, and another vehicle was attempting to exit the same parking lot, the brake pedal was depressed; however, the vehicle failed to respond. There were no warning lights illuminated. The contact's husband depressed the brake pedal, the brake pedal seized, and the contact had to veer and downshift to first gear to avoid crashing into the other vehicle. The vehicle was taken to an independent mechanic who diagnosed the vehicle with vacuum pump failure and a fractured part from the vacuum camshaft. The vehicle was not fully repaired. The local dealer was contacted; however, the vehicle was not repaired by the dealer because the vehicle was not under recall and parts were on back order, as per the dealer. …

My 2019 Chevrolet Colorado, equipped with the 3.6L LGZ engine, recently triggered a P0024 diagnostic trouble code. This code indicates a failure of the Bank 2 exhaust camshaft position actuator solenoid, a critical part of the variable valve timing (VVT) system. After researching, I discovered that General Motors has issued Special Coverage N232430470 for this exact issue on the 2020 Chevrolet Colorado, which uses the same LGZ engine and solenoid system. Despite the identical failure and engine design, my vehicle is not currently included in the coverage. I believe this reflects a systemic defect that affects multiple model years - not just 2020 - and that GM is choosing to limit coverage unfairly. This failure can result in check engine warnings, drivability issues, reduced fuel economy, and possibly emissions system non-compliance. …
In and out of the shop for the last 3.5 years (Warranty is expired now) with multiple engin codes (CEL). Most having to do with the fuel delivery systems. Most common P026D, and P1089. It has been in the shop at least 6 or more times. GM won't stand by their product. Since the warranty ended I've put mor than $4,000 in to repairs for this and now I'm told it will cost me anouther $6000 to $7000 to repair. I bout this truck used with 60,000 miles on it and paid cash $50,000 to the dealer the originally sold it to the previous owner. I just want them to fix the issue once and for all. To date they have just thrown parts at it but it never fixes the problem. They have changed the MAP sensor, the fuel rail and pressure regulator, the injectors, and they've re-wired part of the wiring harness. None of this has solved the issues.
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.
The High Pressure Fuel Pump detached from engine and snapped off flange and bolt in the head of engine . The part is available for inspection and was removed by dealership. Vehicle was being driven at highway speed at time of failure. Narrowly avoided an accident as truck lost power and went into limp mode. There was no prior warning leading up to failure.
Ignition Key Cannot Be Removed and / or Does Not Rotate to the Off Position. This has been going on for about a year and I have taken it to the dealer 3 times and they are unable to fix the issue. I have searched online and there are many Chevy Colorado owners facing this issue. https://www.cargurus.com/Cars/Discussion-t58416_ds944027
Engine Light turned on. Fan keeps running for 10-15 minutes after truck is turned off. Went to two different mechanics and it is a thermostat problem. Temperature sensor and thermostat both have gone bad in under 5 years. They have told me it is not a good design and now parts are in back order. This needs a recall.
