Driving vehicle on road and warming for stability track comes on then warning for power steering comes on and I lose all power steering. It has happened five times in the past three weeks

We purchased a 2015 Chevy Colorado in March of 2015. Mid May 2017 we ran into a huge issue where randomly the power steering goes out. Since that day it has been going off randomly, and the only way to try to reset it is it to keep turning the car on and off until it kicks back on-often at the same time it often says stabilitrak disabled. Usually this happens when the vehicle is in motion, but sometimes has also been already the case when the car is first turned on. We have brought this to the dealer's/service manager's attention every time we go to the dealer (we have gotten every oil change, service and inspection done at a Chevy dealer since the day we purchased the vehicle) and the response we get is that we need to bring the vehicle in while it's "coded". frankly- this is absurd and not at all feasible.

From 30 Mar 18 to 30 Apr 18, every time I drove the vehicle, I would loose power steering and stabilitrak after driving about 8 miles. Tried shutting the engine off and wait about 3 minutes and system would be back online.

Please see complaint numbers for background: 11091275, 11091278, 11091280 on 1 May 18, after I started the vehicle to go to work, warning light came on, with the message: 'service power steering (ps), drive with care. I cleared the message and another message came on: 'service stabilitrak. Tried shutting down the vehicle and restarted 3 minutes later. Drove to work with no ps. Left work and the same thing happen, no ps all the way home. I am not the only owner of a Chevrolet Colorado 2015 that has experienced the same problem. Except when our vehicles were made, they did not fall under the Chevrolet Colorado 2015, but we still have the same problem. Is the NHTSA going to help?

From 26 to 29 mar18, had several instances in which the 'service power steering (ps), drive with care' & 'service stabilitrak' came on with the subsequent loss of ps. On 27 Mar 18, I received two emails from onstar stating the following: Issue with stabilitrak stability control system in your 2015 Chevrolet Colorado has been detected. Please service your vehicle within 7 days'& 'issue with antilock braking system in your 2015 Chevrolet Colorado has been detected. Please service your vehicle within 7 days'. took back to dealer with copies of above related messages, who stated this would allow to better pinpoint the problem with the vehicle. Service manager called later that day stating warranty has expired 2 months ago and that I would be responsible for repairs. He said steering column had to be replaced & would cost around $1,800, but after consultation with factory, they were willing to cover about half the cost and I would be responsible for about $650.said that they would have to order the part ' back order & no idea when the part would arrive.

Steering or power assist system stops working making it hard or imposible to steer. This happens at any time, with vehicle stopped or in motion. My vehicle was manufactured 12/14 so it is not included in recall # 16V054000, but nonetheless the malfunction is the same.

I was driving on the freeway and a light came on and said service power steering drive carefully. I then pulled over and let the car sit to see if it was a error. Nope back on the freeway and it happened again. Then shortly after a light came on and said service stable track. I've been reading lots of links with people saying they are having the same problem.

Power assist and stability am system warning comes on while driving called Chevrolet to see if a recall but no luck.steering wheel becomes stiff and hard to control I think this is a safety issue and should be fixed for being a real problem and should be addressed accordingly..

The power steering goes out without warning, stbilitrak also. Car rattles in the front steering area when ging over bumps in the road. There is a recall for 1/15-3/15 build date only which is insane because mine built in 11/14 has the same parts and the same defects. Dealer and GM refuse to help. Claim there is no fix when they know there is. It is even listed on the Chevy and nthsa websites

My Colorado has 42K miles and on 5 different occasions I have been driving 45+ mph and suddenly warnings begin popping up on the console, "stabilitrak disabled" "traction control disabled" "power steering disabled, please drive with care" turning the truck off and then back on temporarily fixes the problem but it is continuing to happen and is incredibly dangerous! there is a recall for 2015 Colorados for this exact problem; however, GM specified a 2 month manufacturing window where it applies to the recall. GM needs to step up and recall all 2015 Colorados for this before someone gets killed.

I was driving onto an exit ramp and felt the steering get stiff. The informaction screen above the steering wheel flashed yellow lights and the message "service power steering, drive safely". I proceeded to grip the steering wheel harder and slow down till I could safely pullover. The backup camera also stopped working, which makes me think this is an electrical issues since the car has electrical power steering. Once I turned the car off and on back to normal but this seems to be affecting other 2015 Colorado and GMC canyons. Due to the weight and size of this vehicle this issue can cause a major and fatal accident.
