2016 Chevrolet Colorado

The contact owns a 2016 Chevrolet Colorado. The contact stated that while driving at an undisclosed speed, the power steering and stability-trak warning lights illuminated. Additionally, the contact stated that the steering wheel failed to turn in the intended direction. The vehicle was almost involved in a crash because of the failure. The vehicle was taken to the dealer; however, the failure was not duplicated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact stated that the failure was persistent. In addition, the contact stated that when the vehicle was turned off and restarted, the warning lights were no longer illuminated. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 127,000.

I was driving down the road and the power steering completely stopped working. This could have easily caused a wreck. No warning lights or indicators were prior to failure. I pulled the truck over to avoid causing a collision and turned the truck off. After shutting down for several minutes the warning lights that appeared while I had been previously driving went away and power steering returned. I brought it to a shop but they said without the lights being active they couldn't diagnose the problem. This is super dangerous and I see many others with this model have the same problem.

-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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

My power steering went out while driving at 70mph on my way to work. This was accompanied by a dashboard warning lights "Service Power Steering" along with "Service Stabilitrack". I nearly collided with another vehicle being unable to lane change quickly. I took the vehicle to a local Chevrolet dealership, Napleton of Beaver Dam, WI 53916. They diagnosed it as "Electric Power Steering Rack and Pinion Assembly Steering Wheel Torque Sensor Shorted". This required the replacement of the Steering Rack and Pinion Assembly at a very inconvenient cost of $2542.25 parts and labor. After doing a bit of research I found that this has been a problem with the 2015 and 2016 Colorado.

The contact owns a 2016 Chevrolet Colorado. The contact stated that while operating the vehicle, the power steering and traction control warning lights remained illuminated, and the steering wheel became difficult to turn in either direction. The cause of the failure was not yet determined. The manufacturer and local dealer were not yet notified of the failure. The failure mileage was 100,000.

The power steering will suddenly go out while a “Stabilitrak” warning comes up on the display. There are many reports of this problem documented online in this year and model, and the 2015 had a recall for this known issue that was evidently not resolved OR recalled for the 2016 model. Suddenly losing power steering when traveling at highway speed or making a turn is a tremendous crash risk as it is very difficult to turn the wheel and the responsiveness and ability to turn quickly is greatly diminished. I and my wife have both almost crashed when this has happened. Most of the time turning the vehicle off and then on again will reset and reactivate power steering, other times it does not. I have called two Chevy dealerships who acknowledged an awareness of this problem, but difficult to replicate the problem on demand, and not always the same repair but almost always related to the steering rack and cable bundle. As I understand it, replacing the entire rack is about a $2000+ repair that based on anecdotal information online seems to resolve the problem. I am shocked Chevy/GMC is willing to assume this liability and not issue a recall or at least offer some kind of reimbursement option for doing the right thing and getting the repair done rather than place others at risk on the roads. This problem has been going on and off for the past year.

I am submitting a safety concern with my 2016 Chevrolet Colorado truck. This vehicle is experiencing intermittent loss of power steering assist, which poses a significant safety risk. This issue mirrors the defect described in the GM Recall 15595A, which affected 2015 Chevrolet Canyon and GMC Canyon models. The root cause appears to be a poor electrical connection in the torque sensor harness connector. However my vehicle hasn't been included in the recall despite exhibiting identical symptoms. I urge the NHSTA to investigate and consider expanding the scope of Recall 15595A to include affected 2016 models. I am also requesting guidance on how to proceed with repair assistance or reimbursement.

Power steering failure identical to Recall #16V054000 (issued February 2016) on 2015 Colorado. Vehicle will unexpectedly lose power steering udden stiff steering and both “Service power steering” and “Service Stabilitrak” warnings appear on dashboard. Defective parts appear to be gear assembly (GM part #23228020) and revised torque sensor cover kit (GM part #84344239)

After purchasing my 2016 Chevrolet Colorado Z71 (approx. 113,000 miles) from Avalon Honda in New Jersey, steering began to exhibit an intermittent, jerky, “cog‑like” feel—almost as if slipping or catching. It’s unpredictable but recurrent, raising serious concern for sudden loss of control and potential collision. A repair shop replaced the front passenger‑side control arm, but the issue persists. It comes and goes, making it difficult to diagnose. I believe this may be a hidden steering defect that needs formal investigation.
