    2021 CPO Colorado, bought used with 27,000 miles. KEY STUCK IN IGNITION. After 9 months of occasional use the key is, more times than not, getting stuck in the ignition when the truck is turned off. You cannot leave it this way because some systems are still energized. You have to repeatedly put it in and out of park till the key comes out. An associated problem is lock/unlock. The fob and switches will not operate the lock unlock function. It is suspected the park problem makes the vehicle think the vehicle is being operated. It will also not let the remote start function work either. The dealer cleared a code and the problem is temporarily solved. They will not cover it under CPO because they cannot duplicate the problem despite the lock unlock not working at their facility. They ordered a new Gear Shift Mechanism for $800 and I am waiting for it to come in. It has been a few weeks of waiting thus far. It is theoretically possible to have the key get stuck and the doors staying lock...

    While driving a 2021 Chevrolet Colorado on Interstate 95 in Florida, the vehicle suddenly experienced a loss of brake assist. The brake pedal became extremely hard and very difficult to press. The driver had difficulty slowing the vehicle and had to use the emergency brake to help bring the vehicle to a stop. This occurred on Interstate 95, which is a very busy highway with high-speed traffic. The sudden loss of braking assistance created a serious safety hazard and could have resulted in a crash. The vehicle was taken to a repair shop where the mechanic diagnosed the problem as a failed vacuum pump that broke and damaged the exhaust camshaft and related components. The repair required replacement of the vacuum pump, exhaust camshaft assembly, camshaft actuator and solenoid, and valve cover gasket. The total repair cost was approximately $2,329. The vehicle had approximately 64,348 miles at the time of the failure. No warning lights or prior symptoms were noticed before the failure...
