While driving the vehicle has lost power steering assist and stabilitrak intermittently on multiple occasions. Alerts flash on the screen and warning lights illuminate and ofcourse the steering will jerk back from a turn (if you're actively in one). Fortunately, I have taken photos in the past and actually had it occur on my way to an oil change today. They checked the code it comes back to "C0545" which can be found on GM bulletin "pit5437B" that identifies this problem back in September 2015. The cherolet service technician who diagnosed this on my vehicle informed my service department adviser that the vehicle is not safe with the problem, which of course was relayed back to me. So, if a problem Chevy identified in 9/15 makes a vehicle unsafe to operate, why does Chevrolet want me to pay $1700 + tax instead of including my vehicle in the recall that addressed the same issue (NHTSA campaign number: 16V054000)?

The contact owns a 2015 Chevrolet Colorado. The contact stated that the steering wheel seized without warning. The same failure occurred multiple times. The dealer (dublin Chevrolet, 4200 john monego ct, dublin, ca 94568) stated that the power steering gear and pinion needed to be replaced. The manufacturer was also contacted and was unable to assist. The vehicle was not included in NHTSA campaign number: 16V054000 (steering). The vehicle was not repaired. The approximate failure mileage was 79,000. The VIN was not available.

Power steering failed at 50 mph in right turn, steering wheel jerked out of my hand in a right turn. The truck went hard left towards opposing traffic. Steered with difficulty back in my lane. This is the 5th time the steering has failed. Stop the truck and turn off the engine will normally reset the steering.

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

Power steering fails at random times at any speed creating extremely dangerous driving situations in a relatively large truck. It is difficult for me (a 180 pound man) to control the vehicle without the steering assist and nearly I had a serious accident as a result. There was a partial GM recall on 2015 Chevrolet Colorados for exactly this reason (recall # 15595A) however, the dealer said this 'did not apply to my VIN' and expects me to pay 1,700 dollars to replace a flawed system with the same flawed system. The problem I experience is identical to the issue described in the recall; on top of this, my vehicle only has around 43,000 miles. Loss of power steering given my vehicles low mileage, good maintainence record and that I have never placed any significant mechanical strain or been in an accident clearly indicates to me, particularly given the strikingly applicable recall I mentioned, that this is a manufacturing error. I have found literally dozens upon dozens of similar complaints on forums, including one accident that resulted from this. I frankly am very frustrated with GM and feel that if their shoddy design is putting my and others lives in harms way, at least they should pay to replace the system with the same crummy system.

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.

The power steering assist failed, making the truck unsafe to drive. The vehicle was stationary and running at the time of failure. The traction control was disabled at the same time.

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?

My power steering was compromised, almost locking up when an inticator light stated there was a problem with the power steering and to drive with caution. Luckily, I wasn't going very fast. If this would have happened on the freeway, it could have been an accident. I often drive my family, including my young granddaughter around. Chevy will not honor the recall, which is out there for some trucks, just not mine. I feel they should fix this, no matter how many miles are on the truck. Mine had 46K when it happened. It is going to cost $1800 to fix their problem!!!

Power steering failed several times this week making it almost difficult to turn steering wheel. This is a safety hazard. This happened while vehicle was in motion on a city street..

- Omaha, TX, USA

Vehicle has less than 30K miles and is 28 months old. While driving, loss of power steering has occurred twice and the display states service power steering - drive with care. The first time was at an intersection waiting for a green light. The second time it happened was at 45 mph in light city traffic. Vehicle VIN not included in recall #16V054000 or GM recall #15595. Vehicle has been at local Chevrolet dealer for over a week and repair parts can not be located. Seems that this is a recurring problem of many Colorado not affected by the above mentioned recall.

- Pensacola, FL, USA

I was driving and then my power steering went out and a caution light said power steering failure and drive with care. It was very scary because I could hardly turn my steering wheel. I was scared that I was going to crash.

On 6/26/17, I took my truck to paradise Chevrolet in temecula, ca because a few days before my power steering failed while I was driving. My truck was under warranty because it had only 19,968 miles. They said nothing was wrong with the truck so they just recalibrated it. On 3/24/18, the power steering failed again, once on a city street and once on the freeway while driving to paradise Chevrolet. Today I received a call saying something was wrong with the steering wheel & it will cost me $1250 to fix the problem. My truck has alittle under 30,000 miles.

Driving on the highway @ 45 mph, the "service power steering, drive carefully" sign came on. The power steering stopped working and the vehicle was very difficult to steer to the side of the road. I shut off the engine and restarted the problem went away. The next day on the way to the dealer the same thing happened at 55 mph. This tin=me I continued driving to the dealer so they could see the problem. The dealer verified the problem was in the steering gear and would cost $2000 to repair. This is a safety problem, listed in a partial recall by GM, which does not include my VIN. The NHTSA should be investigating this before something catastrophic happens, perhaps to a family driving down the road.

22 Mar 18: While driving my Colorado lt at 30mph, 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'. I went to work and parked it and 3 hours later, steering was normal. 23 Mar 18: On the way to the dealer the truck had no problem with power steering.(O'reilly Chevrolet in tucson, AZ) and explained them the situation. The dealer test drove the vehicle and had no loss of ps. Vehicle was through the dtcs and found dtc U0420/42; torque sensor not properly learned. Dealer did pscm setup& cleared the dtcs. Service person stated they had to reboot computer. Afterwards, they drove the vehicle & had no malfunctions - $153.24. On way home, had no problems, to include the weekend. 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.
