2022 Chevrolet Colorado

Tried to order a part and was told no longer available.

The brake booster vacuum pump failed catastrophically while driving, resulting in a sudden, dangerous loss of power braking assist and a rock-hard brake pedal. Upon inspection by a mechanic, the pump's internal failure violently sheared and destroyed the engine's exhaust camshaft, requiring a complete camshaft tear-down and replacement. This is a severe mechanical defect causing both immediate highway safety hazards and internal engine destruction.

Brake assist suddenly went out. No warning lights what so ever. Happened thankfully when pulling into my driveway at slow speed. Had to stand on the brake pedal to get stopped. If this would have occurred at interstate speeds. It would have been bad.

The contact owns a 2022 Chevrolet Colorado. The stated that after shifting to park(P), the contact was unable to immediately remove the key from the ignition switch. After several attempts, the contact was able to turn the ignition switch to the off position and remove the key. The vehicle was taken to a local dealer to be diagnosed, and it was determined that the shifter assembly needed to be replaced. The vehicle was not yet repaired. The failure mileage was 54,000.

While driving our 2022 Chevrolet Colorado ZR2 (VIN: [XXX]) through an active roadway intersection at approximately midnight, the vehicle experienced a sudden, uncommanded complete loss of motive power and stalled without advance warning. Our teenage daughter was driving, making the abrupt loss of power, steering assist, and vehicle control in live traffic especially dangerous for an inexperienced driver. The stalled truck had to be physically pushed out of active traffic lanes into a nearby gas station for safety and has required flatbed towing for all subsequent transport. In the days prior to failure, an intermittent, unidentifiable mechanical odor was noticed, but zero warning lamps, dashboard messages, or diagnostic trouble codes were displayed, and the vehicle drove normally until the sudden shutdown. At the scene, an OBD-II diagnostic scan pulled DTC P0019-00 (Crankshaft Position - Exhaust Camshaft Position Not Plausible Bank 2). An independent service center subsequently confirmed adequate, safe oil levels (ruling out oil starvation), and independent technicians confirmed catastrophic internal engine failure. The truck is currently at an authorized Chevrolet dealership undergoing formal diagnostics to determine the exact internal failure mechanism (including potential correlation to known bearing/valvetrain defect patterns under GM Bulletin 19-NA-256). The vehicle and components are available for inspection upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on the freeway, I experienced a sudden issue with the vehicle’s braking system. The brake pedal became extremely stiff and difficult to press, and the brake assist stopped functioning. I was still able to apply the brakes, but it required significantly more force than normal to slow and stop the vehicle. Prior to this incident, I had also noticed an issue where the engine did not shut off normally after removing the key. The engine continued running briefly before shutting off with a noticeable rumble/shudder. I do not know whether the two issues are related, but I am including this information because it occurred before the brake-assist failure and may be relevant to diagnosing the vehicle.

Loss of power steering, Truck repaired by GM dealer, he stated it was the same failure mode described in Recall notice N2023254 10. The repair even though the same as the previous failures was not covered by GM because my VIN was not in GMs recall notice. Looking at this website there a number of reports of power steering failures for later model Colorado and Canyons that were not covered by the recall. Either GMs fix was not effective, or they did not select the right VIN population. So the Power steering failure repair on my truck even though it is the same failure mode as the previous recall was not covered by GM.

Component that failed: brakes. I was pulling into a parking spot at low speed and the brake pedal was suddenly extremely difficult to depress, almost impossible. It felt as if a brick were under the pedal but there was no obstruction. I was able to stop only because I was already going so slow. Safety of myself and others was at risk because I was almost unable to stop the vehicle. If I had been going any faster I don't believe I would have been able to without crashing into an obstacle. Vehicle is currently at a service shop but issue has not been verified or repaired as of today. When restarting the vehicle, the engine stuttered and started making odd sounds, and wouldn't idle properly. There were no warning lamps, messages, or other symptoms at all prior to failure. When I entered the parking lot it was working normally and when I turned to enter a parking spot the brakes suddenly just failed.

The contact owns a 2022 Chevrolet Colorado. The contact stated that while parking the vehicle, it was difficult to remove the key from ignition switch. There was no warning light illuminated. The contact stated that the failure was a recurring failure. The dealer was contacted, and the contact was informed that parts were on a national back order. The manufacturer was not made aware of failure. The failure mileage was 23,750.

key will not release from ignition. I will put the truck in park but the computer will not read that it is in park, so the key can only be rotated to the accessory position. This has been confirmed by the dealership. No codes are coming up nor any lights on the dash.
