Colorado truck has been experiencing intermittent failure of power steering system for several weeks. This has occurred on start up and also while vehicle is moving. The problem may resolve temporarily on its own and then recur at another time. Watson Chevrolet evaluated this problem on 9/28/22 and found -??DTC UO420 42 Which states that the power steering control module was not properly calibrated, causing the electronic brake control module to lose communication with it. Reprogram the PSCM. Condition is no longer present.-?? The problem reccurred while driving on September 30, 2022. Chevy dealership has been notified and the vehicle will be taken back in for further evaluation.

While driving on the highway "service stabilitrack" warning suddenly appeared. The warning went away, but the light on the dash stayed illuminated as if I had manually turned off stabilitrack. Dash then indicated traction control was turned off, speedometer, rpm gauge, and temp gauge all started bouncing around and fuel range indicated "--". Also received a warning that power steering is not functioning. Vehicle would not appropriately change gears (automatic transmission), causing issues maintaining speed. I have a video of the gauges (taken by my partner while I was driving) that can be sent via email, or screenshots can be uploaded upon request. An online search yields several forum posts indicating this is a repeated issue for this model year, causing significant safety issues and leaving individuals stranded. Within forums I discovered a service bulletin regarding the issue, but it appears no one felt this was important enough to issue a recall or notify owners. I have not yet been able to get to a dealership for repairs, as this occurred on a weekend (while I am 14 hours away from home), but I will be contacting a dealer Monday morning.

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.

Has happened multiple times where driving and notification comes on dash that Stabilitrak and Power steering are malfunctioning and then stop working. Has happened in the middle of a turn and the wheel turn to lead in my hand and I almost crashed. Every time it happens the only way to fix it is to pull over and reset computer and pray it doesn't shut off again while I'm driving. I've spoken to numerous others with the same year and have had similar electrical issues, as well I have seen dozens of people posting online asking the same questions so i know its not just my car and I know there is a recall out for the same part on the '15 Chevy Colorado. The issue of bringing it into the mechanic to fix is that if nothing is going wrong at the time they can't see the issue. This is an extreme safety issue. more than once the power steering has shut off while taking a steep turn. GM needs to be help accountable to fix this issue.

The vehicles power steering system has failed on at least six occasions while being operated over the course of the past 30 days. When the power steering system fails the vehicle display gives two warnings: First, steering assist is reduced drive with care. Second, service stablitrak. This puts the safety of the operator and others at great risk as the vehicle becomes extremely difficult to steer, especially at low speeds, as well as limits the driver's ability to drive reactively to their surroundings. This extreme loss of control has lead to uncomfortably close near collisions on two occasions. The problem has not been reproduced or confirmed by a dealer or service center. The vehicle has not been inspected by the manufacturer or any other entity. There were no other warnings lamps, messages or other symptoms of the problem prior to the failure. However, the problem is highly common and with the use of a search engine one can easily come to the conclusion that the manufacturer needs to be held responsible for their faulty craftsmanship in reference to this issue.

Common problem reported by many consumers, infotainment system changes stations, randomly shuts down, fast forwards songs on media, touchscreen non-responsive. Had mine replaced to the tune of $800+ and the same thing is happening to the new unit. Only this time, I get the entire system cutting out and then only the front tweeters coming back on after a minute. New unit does not have adjustable back up camera view, too bright at night when backing up, glare causes me to be unable to see.

While driving the steering wheel locks up and it says service Stabilitrak and engages the traction control and will not let you steer your vehicle at all, this could be fatal at hight speeds and I am shocked that this is not a recall I've seen hundreds of complaints online about it.

I was driving on the high way and the power steering went out almost sent me into another car

Key gets locked in the ignition after you put it in park and try shut off the vehicle. Vehicle won-??t turn off. It takes 10 to 20 minutes before it will release the key. I believe this is a safety issue and have seen a good amount of people online that have the same issue and the manufacture refusing to address or fix the problem.

Wire chaffing by the AC suction line and by the serpentine belt near fan clutch, almost got me killed. WE NEED A RECALL ON THIS ASAP, this is a common problem being overlooked by GM.

Sudden loss of power steering while driving. Difficult to control vehicle. Has happened about 10 times in the last two weeks. Also occurs during cold start, less frequent. Restarting returns to normal operation until it fails again. Dash message indicates stabilitrack and power steering disabled. Appears to be same problem as 2015 model recall

While driving the vehicle, the drivers information display in the dashboard changed from speedometer to radio information, the radio turned up, and on the infotainment unit; I could see it scrolling through channels. I pulled over and returned the settings to normal and as I pulled out, the system started trying to make phone calls through my connected phone. Additionally, while this was happening, it seemed that I had no other normal system sounds (i.e. blinker, seatbelt reminder, etc.) Later while driving on the same trip, the infotainment unit turned on my backup camera while driving and continued to change vehicle settings including reciting navigation directions from an earlier trip. Needless to say, this caused a fairly significant distracted driving scenario.

I'm a couple of different occasions I went to start the truck and it would not turn over and it flashed a warning about servicing the stabiltrak and the trailer brake system. Both of these systems checked out fine by the dealership. All the online forums I have seen seem to indicate that this is an issue with the wiring harness not being properly mounted and chafing causing shorts in The wire system. I've been to the dealership twice and they claim to not find it but I don't know how hard they're looking at the wiring harness.

Infotainment screen goes crazy at random times while vehicle is in use. Screen jumps around and randomly changes, radio stations change, dashboard speed display changes screens as well. This is a very bad distraction while driving. I have video of this saved on my phone. I was able to pull over to record it yesterday (9/28/21). This problem has been happening on and off at random times for over a month. I have spoke to my dealer about it, and made an appointment for evaluation. I have also contacted Chevrolet service to see if it will be repaired at no cost as a safety issue.

When it first happened, I cranked my vehicle and seconds later, a chime and two messages went across my dash saying "Stabilitrack disabled." "Power steering disabled." and both were inoperable. I restarted the truck, and it ran fine. Happened again two weeks later. Then two weeks after that, it happened suddenly WHILE DRIVING down the road. Again, it worked properly after restarting, but it's started to be a constant. Now it immediately shows "Stabilitrack disabled" after starting and the power steering goes after about 10-15 minutes of driving, like clockwork. There were no lights on or any other warning indicators prior to this happening. It was a sudden issue with an otherwise unproblematic vehicle. I see there was a recall for a bad wiring harness connection that caused exactly this for the 2015 year model. Mine is a 2016 and no recall exists. I've seen a few other forum posts stating their 2016 has done this as well. I have not yet taken it to a mechanic/dealer, but that is my next action. It is available for inspection. Needless to say, this is extremely unsafe for both myself and other drivers on the road. Losing the ability to (positively) turn at an inopportune time could be catastrophic.

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. This problem happened about 4 months ago and had not reappeared until the last few days 06/19/2021. Now it happen twice since. Upon restarting, the vehicle drove normal. 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. I will be bringing it to a deal in Freehold, NJ. 1 Affected Product
