Happened twice now while driving, power steering suddenly lost and two messages on dash: Loss of Power Steering and Stabilitrak. Pulled over and turned off ignition. When restarted all errors automatically cleared and systems appear to be functioning correctly. Steering without power assist is very difficult and high safety concern at low speed driving.

-What component or system failed or malfunctioned, and is it available for inspection upon request? 2016 Chevrolet Colorado VIN: [XXX] Engine: 2.5L I4 (camshaft-driven brake system assist vacuum pump failure). GM Technical Service Bulletin 21-NA-268 (Nov 2021) confirms that if vacuum pump drive lugs are broken, replacement of both the vacuum pump and the exhaust camshaft is required which was the case. Parts kept by repair facility that performed service. Autonation Chevrolet South Clearwater FL 33764. -How was your safety or the safety of others put at risk? May, 2025 the vehicle experienced a sudden loss of braking (hard/stiff brake pedal). This is a safety-critical failure. -Has the problem been reproduced or confirmed by a dealer or independent service center?Yes by shop stated above. Diagnosis showed a seized engine brake system vacuum pump (driven by the exhaust camshaft) that had sheared drive lugs and produced metal debris which damaged the exhaust camshaft and associated components. The repair required replacement of the vacuum pump and the exhaust camshaft; my total repair cost was over $4,000. The camshaft was not readily available and I required a rental car for over 30 days while waiting for parts. -Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? System and parts inspected by shop above. GM Special Coverage N182202780 (Apr 2019) addresses vacuum-pump related decreased brake assist for certain 2014–2017 GM trucks/SUVs, but Colorado is not listed in that bulletin’s model list. -Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Check Engine came on at time of brake loss (Brake Vacuum Pump Failure). Immediate system failure. I request NHTSA send me a copy of any investigation number or record created for this complaint, and I request guidance on whether I may be eligible for reimbursement under any GM program.

SERVICE BRAKES

The brake pedal suddenly became very stiff with no warning while driving at highway speeds. Braking was very difficult and required me to swerve into another lane to not impact a car and run a red light. I managed to stop afterwards. This was caused by the cam driven vacuum pump failing. No warning of any kind was given.

While driving the truck randomly loses power steering. The display screen states that the anti-lock brake system needs to be serviced. Once I turn the truck off and back on it seems to reset and work as normal. The dealer will not fix due to the truck not having any check engine lights on. This is very frustrating and a safety issue that Chevy needs to look at.

My power steering on my 2016 Chevrolet Colorado went out on a 30mph turn and nearly lost control of my truck. As I was driving, I slowed to make a stop on a city street when there was a sudden loss of power steering. It was very difficult to steer and turn but I made it to the side of the road. The vehicle did not lose power or shut off. The message said there was a loss in power steering and to seek service. The traction control and stability track warning lights turned on. I turned off the vehicle. Upon restarting, the vehicle drove normal. I drove back home feeling unsafe. It is a safety hazard. This is definitely a safety issue and it should be taken care of by Chevrolet. This should be forced to be repaired. This is a safety hazard for the public, the operator, and anyone riding in the vehicle.
