On two occasions my 2015 Chevrolet Colorado has lost all power steering assist and stability traction control. On both occasions I was on a highway traveling B/w 50-55 mph. Warning lights came on that I had no power steering assist and to be cautious.I had no power steering and had to manually steer to a safe are. After turning the vehicle off and back on, the power steering assist came back. During the incident steering G was difficult and could have led to an accident.

While driving at speed traction control or stability (T/C) dash deactivation warning lite and audio warning activate, total loss of power steering. Driving on city street, under speed limit pulling a lightly loaded trailer in a straight line. Managed to pull the truck to the side of the road. Turned off truck checked under the hood nothing was out of place start up everything normal. 3 days later same thing driving in a straight line into a "round about" warning lite and audio warning activate came close to not making the "round about" exit this time without a trailer in tow. Shut truck off once on side of road restart everything return to normal. I took truck to my Chevy dealer no codes were found. There was a closed recall for this issue. Manager said this truck was recalled and fixed but not while I own it. Dealer took no action since it was ok then and no codes. I'm to bring it back if it in the failed mode. Purchased in Nov 2015 used with 2000+ miles now has 42524 miles on it. With little warning steering goes from power to almost impossible.

Dash lights for ABS, traction control, and stabilitrac go on and off I had it in to the dealership before they said it was nothing it back and I am bringing it in again.I read online that there was a recall but only for certain regions also read this is happening in other areas like with me. Seems dangerous with brakes and traction control and stability. It happens while I am on the road would hate to have myself or someone else hurt if there is something wrong.

Back in early 2018 prior to my bumper to bumper expiring, I had the check power steering and stabilitrak come on on dic. I took it to dealer but they stated could not find any issues. This keeps happening but everytime I turn truck off and then back on as stated in owner's manual, problem goes away. More recent past week, it has been happenings again but more frequent to which at times, turning off and waiting then turning back on, the problem persists. This problem happens various times (while driving city, highway, as I'm turning vehicle on for first time in the day, while backing up, while parking). I have mentioned and taken in to dealer or other places but no codes are found and problem cannot be duplicated.

Lost power steering, warning light came on after the issue, could not steer the vehicle, luckily it happened in the driveway, very dangerous if it happened on the road warning lights for power steering service (drive carefully) and stability controll warning

- Warren, RI, USA

While driving at highway speeds an audible warning came on along with a service power steering and a service stabilitrack message. All power steering was lost and the truck became extremely difficult to control. I was able to pull to the side of the road. Power steering returned after a power cycle of the car. However the same failure happened during my next trip, again at highway speeds. I was lucky that this happened on a straight section of freeway both times as the truck is practically uncontrollable when this happened. A review of this issue on the internet reveals that a recall has been issued for this issue. However, it starts with vehicles manufactured in January 2016, but this vehicle was manufactured one month before the recall effective period.

Turn the truck off and on again there was no longer any warnings displayed, and all functions were normal.

- Columbus, OH, USA

I was on my why home coming up to a red light. I was at a crawl when service stabilitrak came up on my screen. I lost all power steering, so it was difficult to turn the vehicle at any speed. I have looked up to see if anyone else has had this problem. I have found that it isn't super common but seems like way too many vehicles are having this issue.

Experienced a failure of the steering system (power assist stopped working) first on Saturday, September 28, 2019 at approximately 35 mph speed; and subsequently on Sunday, September 29, 2019 at approximately 65 mph; then, on Monday September 30, 2019 and Tuesday October 1, 2019. The vehicle is currently with dealer where it was purchased. Two warning lights appeared each time the steering failure occurred. Also, two messages display in the digital display within the "dashboard": 1. service power steering (drive with care) 2. service stabilitrak vehicle steering immediately compromised, very difficult to steer with dangerous change in effort required to steer, loss of control due to steering change. In each case, slowed speed to adjust to changed steering condition. Upon researching this defect, see many references and documentation to exact same conditions and defect described here. Manufacturer (Chevrolet/GM) has acknowledged equipment defect - with recall, but not yet for VIN of my vehicle - appealing this here/now due to multiple reports of defect to same year, type vehicles not recognized by Chevrolet/GM yet with appeal for confirmation to recall this and similar vehicles (2015 Chevrolet Colorado)

Power steering on my 2015 Chevy Colorado as well as stable track goes out intermittently. It can happen when I'm driving or starting the car. Turning the vehicle off and on again usually fixes the issue temporarily. Took the vehicle to the mechanic and codes CO545, U0420, B1325 and U04135 which are the steering wheel torque sensor, invalid data received from power steering control module, control module power current voltage below threshold, and invalid data received from brake control module. The truck is barely 4 years old and to replace the part will be 2300. It is exhibiting the same issues as the recall in 2016 and searching around I find more people having the same issues.

My truck rang 3 times and a prompt showed up on the dash saying service power steering and loss of stabilitrack. I was sitting at the drive thru and had to pull straight into a parking spot because turning the vehicle became pretty much impossible. My truck only has 30,000 miles on it.

Power steering failure. My 2015 Chevy Colorado truck, with 41,153 miles, had a power steering failure 4 days ago (March 22, 2019). While traveling on a dry, smooth road at 30 mph and while braking, the stabilitrak "off" warning light came on, as well as a power steering assist warning. There was an immediate loss of power steering, and the steering wheel was very hard to turn. Initially I thought the truck had stalled, but it had not. I was able to make 2 right-hand turns at slow speed to get out of traffic and into a parking lot. I had to use a lot of muscle to steer the vehicle into the lot. I turned off the truck then restarted and the warning lights were off and power assist returned to normal operation. I have not had any problems with the truck until this episode. I checked the VIN number against a recall list and there is no current recall for this vehicle (that I'm aware of). I've placed a call to the Chevy dealer service manager and I'm a waiting for a return call. In the meantime my wife is afraid to drive the vehicle, and I keep both hands on the steering wheel wondering if it'll happen again under less favorable circumstances.

I was driving down the road at approx 30 mph and the power steering cut off and warning lights went on about service power steering. Complete loss of power steering, barely made it to side of road. I turned the car off and on and the power steering came back on. Luckily I was going straight down the highway when it happened. About 2 weeks later the same thing happened, I was driving about 30mph and the power steering cut out and the warning light came on. I barely able to pull to side of road and turned truck off, turned it back on and power steering came back. Again I was lucky to just be going straight down the same highway. I took the vehicle to Chevy dealer in cerritos(penske) and they said they could not get the power steering to fail(I think its crazy to try because that could cause a major accident) after doing research online several other 2015 Chevy Colorado trucks having exact same issue, and they are covered by a recall but mine is not listed in the recall. Why isn't mine included in the recall with the exact same problems?! I suspect Chevy is being cheap and not wanting to pay, very sad because this problem is so dangerous!

While driving two different alarms flashes on dash screen; 1) "service stabilitrak" and 2) "service power steering, drive with care." Vehicle then lose power steering. I have learned that if I pull over, stop and turn vehicle off and then back on the alarms clear and I have power steering once again. I have noticed this situation while driving on flat highway and when vehicle is a little off balance such as on a dirt road. I have taken to the dealer, explained situation and referred dealer to comments online. Dealer stated the alarm history is clear and therefore they have no idea what to do. I purchased vehicle around September 2018 from dealer and this situation has happened approximately 18 times over 4 months or so. It has alarmed, I've cleared it and then alarm again in the same hour. It has also gone weeks without alarming..

- El Centro, CA, USA

Electrical power failure while driving. Vehicle power shut off (2 seconds or so) as I was approaching stop light then came back on. This issue caused me to loose steering and reset all electrical memory systems in my truck. Concern is if this happens when going faster speeds could prove dangerous to family and others. Less that 30K miles on vehicle.

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)?
