2022 Chevrolet Colorado

I was driving along the highway exit ramp when I went to brake; the brake pedal was stiff, and the vehicle wouldn't stop. I had to put my full body weight into it, and that’s when the car came to an abrupt halt. I nearly crashed into the car in front of me. I took it to the Bomnin Chevrolet dealership, and the service advisor informed me that the vehicle had logged a fault code or something similar. The vehicle is currently at the dealership. Prior to the incident, there were no on-screen indicators, warnings, or warning lights. It was only after the brake failure that a message appeared on the screen—along with the wrench symbol—reading "Brake Assist Service."

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.

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.
