2019 Chevrolet Colorado Engine Problems

The contact owns a 2019 Chevrolet Colorado. The contact stated that while the vehicle was parked, the contact saw oil on the ground underneath the vehicle. There were no warning lights illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed with a leaking valve cover gasket. The contact was informed that the valve cover gasket needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the independent where it was diagnosed with a failed CAM shaft carrier gasket. The contact was informed that the CAM shaft carrier gasket needed to be replaced. The vehicle was not repaired. The dealer was made aware of the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 112,000.

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. I am requesting NHTSA to investigate whether this VVT solenoid issue warrants a broader recall or special coverage extension across model years with the LGZ engine (including 2019).

No warning lights or messages or anything. Blown head gasket and a large amount of coolant in the oil. I have an appointment to take it to a dealership the end of this week

The transmission is starting to shutter at high speeds and not shift as intended.

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.

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.
