2016 Chevrolet Colorado Electrical System Problems

FPCM code P069E. Engine stalls when slowing down. Local dealer says to check wires around water pump area if rubbing and unsecured.

Wiring harness problem resulting in loss of power to a/c, and other electrical components such as radio scrolling without being called for, only small portion on left side of touch screen works. Problem previously reported under 11516530. Dealership that sold me the vehicle and other automotive shops want $75 or more just to look at the problem. Current mileage on this vehicle is just over 50,000 miles. [XXX] living in Florida and I have been without a/c since last summer. Prior to that the power steering & brakes would go out without warning. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

07-01-23 Vehicle died out, wouldn't start, got jumped, still wouldn't start. No indicator lights or warnings. Towed vehicle to the dealership, where it was for 11 1/2 months with the determination it was the ECM and Harness. Which it took that long to get. The vehicle was given back 06-14-24, even though it was in running condition, it was discovered parts were missing. Dealership put on order, received by end of July and installed. November 13, 2024, vehicle died out while driving on the freeway. Dashboard lit up everything, had to get the vehicle towed back to dealership. I have the Onstar diagnostics indicating the same components as the original reason the vehicle was held for an approximate year. Dealership now has vehicle and we have to wait for them to do a diagnostic.

The vehicle beeped a warning and power steering stopped working. I cut the switch off and the vehicle reset and everything started working. This happened on August 9,2024. On August 18, 2024 the same thing happened again. I stopped the vehicle, turned it off , and it reset again. Both times the system warning said that stability control had stopped working. Thank you.

Loss of power steering while driving, could cause loss of vehicle control. Issue occurred 3 hours after vehicle purchase and was accompanied by multiple warning lights on dash. Dealer stated they had performed some wiring repair before my purchase, but did not disclose that at time of purchase

It's a known issue that these vehicles have wiring harness chaffing issues in multiple areas. In 2016, a TSB was issued under PIP5416 to address this in 2016 models. It has since been subsequently updated to cover all years through 2021 models under TSB PIP5416B, C, and D because GM failed to acknowledge fix this potentially dangerous and expensive issue. Byers Chevrolet had to repair 6 wires that were damaged from rubbing in and area addressed by this TSB. Upon researching, there are countless reports on internet user forums and Facebook groups of this issue occuring. Being a Fleet Manager, I see all kinds of recalls addressing the smallest issues like tailgate handles, but silence when it comes to an issue as serious as this.

What component or system failed or malfunctioned, and is it available for inspection upon request? Water intrusion to the cab of the truck has structural failure in the roof causing it to leak inside the cab. Leak runs into dash and out of ignition causing electrical issues in the dash and ignition, along with pooling on the floorboards causing rusting; runs into the rear 3rd brake light and rear headliner causing electrical concerns to the rear brake light not alerting of braking and leaks into rear seats causing rusting under the seats where the seats can fall through the floorboards. How was your safety or the safety of others put at risk? rear brake light failure to alert surrounding drivers of braking. Possible electrocution in starting the vehicle with water in the ignition and dash; possible passenger/driver being dropped through the floorboards while driving. Has the problem been reproduced or confirmed by a dealer or independent service center? unknown Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? I have had it looked at by mechanics and told it was a body issue and needed to go to a body shop, not the dealership. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No

When shifting into Park and attempting to turn ignition off, the ignition does not fully rotate to the Off position and I’m unable to remove key from ignition. There are several YouTube videos demonstrating this issue with thousands of views, so the problem clearly affects a lot of people. Some videos show where the ignition safety switch solenoid does not properly disengage when placed in Park. Would be more than happy to have my vehicle inspected and tested, if needed. Have been able to “work around” issue by doing a couple of quick release pops of the shifter release switch. Seems to be a mechanical + electrical issue. Happened suddenly in February 2023 when parking in a busy parking lot. Became very nervous and concerned that I couldn’t turn the ignition off and therefore remove my key. Was not going to walk away from vehicle and leave the key in the ignition either. Have not yet reported to dealer, but that’s my next step. No warning lamps or related lights on dash.

Try to completely shut the truck off but cannot remove the ignition key after putting the truck in park . After several times of starting the truck and moving the shifter back and forth then turning the truck off the key releases. Went on car gurus.com chat line and found this problem is widespread. Chevrolet dealerships will not honor the warranty on this issue if the vehicle is passed it’s warranty. Looks like someone is going have to get injured or trapped in the vehicle for Chevy to acknowledge this safety issue. Thank you for your consideration.

The ignition swich won't turn off in one of ten time. Truck could be stolen & driven away.

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.

The contact owns a 2016 Chevrolet Colorado. The contact stated while the vehicle was parked, the contact was unable to release the key from the ignition. The contact stated that he had to manipulate the steering wheel and ignition switch after approximately 5 mins and the key would release from the ignition. There was no warning light illuminated. Neither the dealer nor the manufacturer was contacted. The vehicle was not repaired. The approximate failure mileage was 49,000.

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.

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.

Today about 4:00 pm driving down the interstate my truck lost all electric dash and radio while driving stayed cranked going 70 mph around Robert Louisiana couldn’t see speed don’t know what is happening with this truck but it has several safety issues from brake assist lights that come on to radio and dash going off

WHEN TURNING OFF MOTOR, KEY GETS STUCK IN IGNITION SWITCH AT RANDOM. KEY CAN STILL TURN MOTOR OFF AND ON, BUT NOT BE REMOVED. HAS BEEN OCCURRING FOR OVER A YEAR.

MY WINDOWS DO NOW GO UP ALL THE WAY WHEN I HOLD THE DOOR BUTTON UP. THEY GO UP PARTIALLY AND THEN BACK DOWN. I HAVE TO MAKE MULTIPLE ATTEMPTS TO ROLL THEM UP. I TOOK IT TO THE DEALERSHIP AND WAS TOLD NOTHING WAS WRONG. JOHN JONES GM IN CORYDON INDIANA DISMISSED THIS ISSUE. THIS HAS HAPPENED WHILE DRIVING AND WHEN PARKED.

DURING ANY TYPE OF MOISTURE IE (FOG, RAIN) VEHICLE GOES INTO REDUCED ENGINE POWER MODE CODES FROM THE ECM P2122 AND P2138 BOTH RELATING TO APP. FIRST TIME IT HAPPENED WAS IN RAIN STORM IN MOTION, APP PEDAL WAS REPLACED WITH NEW OEM PART BUT THE PROBLEM PERSISTS. I SUSPECT WATER INTRUSION FROM WIPER COWLING AFFECTING ELECTRIC HARNESS. THIS PROBLEM DOES NOT EXIST DURING DRY SEASON. AFTER MANY HOURS OF ONLINE RESEARCH I HAVE FOUND THAT THIS IS A WIDESPREAD PROBLEM IN CHEVROLET VEHICLES.
