2016 Chevrolet Colorado Electrical System

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)

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.

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.

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

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.

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.

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.

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.

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.

VEHICLE WILL NOT RELEASE IGNITION KEY WHEN SHUTTING CAR OFF. CAR IS IN PARK AND IGNITION WILL NOT TURN TO RELEASE KEY TAKES MANY ATTEMPTS AND CONSIDERABLE TIME BEFORE KEY WILL RELEASE. IT HAS HAPPENED MULTIPLE TIMES IN PAST 2 YEARS.

TL* THE CONTACT OWNS A 2016 CHEVROLET COLORADO. THE CONTACT STATED THAT WHILE ATTEMPTING TO REMOVE THE KEY FROM THE IGNITION, THE KEY CEASED IN PLACE. THE VEHICLE WAS TAKEN TO A LOCKSMITH BUT WAS NOT REPAIRED. THE VEHICLE WAS TAKEN TO CHEVROLET BUICK GMC OF PUYALLUP LOCATED AT (800 RIVER RD, PUYALLUP, WA 98371) TO BE DIAGNOSED BUT WAS NOT REPAIRED. THE MANUFACTURER WAS NOT CONTACTED NOR INFORMED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 9,000. THE VIN WAS NOT AVAILABLE.

THE DRIVERS WINDOW, WHEN I PRESS THE DOWN BUTTON ON THE CONTROL THE WINDOW WILL START TO GO DOWN THEN CLOSE BY ITSELF, ALSO I HAD AN ISSUE TODAY 11/13/19, I WAS ABLE TO GET THE WINDOW TO ROLL DOWN, BUT THEN NO MATTER HOW MUCH I TRIED THE WINDOW WOULDN'T ROLL UP..THE VEHICLE IS USUALLY IN MOTION WHEN I HAVE HAD THE ISSUE OF THE WINDOW ROLLING UP ON ITS OWN,

RADIO DISPLAY WOULD START TO SCROLL UP AND DOWN. NOW THE DISPLAY OF MILEAGE, OIL LIFE PERCENTAGE REMAINING, TIRE AIR PRESSURE DISPLAY AND OTHER OPTIONS SUPPOSED TO BE PREVIOUSLY AVAILABLE THROUGH PUSH BUTTONS LOCATED ON STEERING WHEEL ARE NOT ABLE TO BE ACCESSED.

WAS RETURNING FROM A 300-MILE TRIP ON JUNE 17TH WHEN I RECEIVED A "SERVICE 4WD" MESSAGE ON THE DISPLAY CONSOLE. CALLED GM DEALER SERVICE SHOP AND SET UP APPT FOR JUNE 28TH (EARLIEST AVAILABLE DATE). THREE DAYS LATER, PICK-UP AUTO-SHIFTED AND LOCKED INTO 4WD. NEXT MORNING, JUNE 21ST, DROVE PICK-UP TO DEALER SERVICE SHOP. TECHNICIAN WAS ABLE TO TAKE PICK-UP OUT OF 4WD, BUT SAID HE COULD NOT GUARANTEE IT WOULDN'T SLIP BACK INTO 4WD. I CONTINUED TO RECEIVE "SERVICE 4WD" MESSAGES. ON JUNE 27TH, WHILE MAKING A LEFT-HAND TURN ACROSS ONCOMING TRAFFIC, PICK-UP AGAIN AUTO-SHIFTED AND LOCKED INTO 4WD. THE WHEELS LOCKED WHILE IN THE TURN, STALLING THE VEHICLE WITH ONCOMING TRAFFIC BARRELING DOWN ON ME. I DID NOT THINK I WOULD SURVIVE. FORTUNATELY, OPPOSING TRAFFIC WAS ABLE TO SWERVE AROUND ME, AND I WAS EVENTUALLY ABLE TO LIMP THE PICK-UP THROUGH THE LEFT-HAND TURN AND OUT OF DIRECT TRAFFIC. VEHICLE WENT INTO DEALER SERVICE SHOP THE FOLLOWING MORNING (JUNE 28TH), STILL LOCKED IN 4WD. SERVICE SHOP HAD THE PICK-UP FOR 18 DAYS. FINAL VERDICT: PIN TENSION ISSUES AND FLUCTUATING VOLTAGES IN CONNECTOR, WHICH MISS-SIGNALED THE VEHICLE TO AUTO-SHIFT INTO 4WD. THIS IS THE THIRD TIME I'VE HAD ISSUES WITH THE 4WD ON THIS PICK-UP. THE FIRST TIME I RECEIVED THE "SERVICE 4WD" MESSAGE AT 214 MILES. VEHICLE AUTO-SHIFTED AND GOT STUCK IN 4WD. DEALER SERVICE SHOP REPAIRED ISSUE. AT 5,096 MILES, THE PICK-UP AGAIN ISSUED A "SERVICE 4WD" MESSAGE AND AUTO-SHIFTED INTO 4WD. WAS DIAGNOSED AS AN INTERNAL SHORT; AND THE 4WD SELECTOR SWITCH REPLACED. THIS THIRD TIME WAS DETERMINED TO BE ANOTHER INTERNAL SHORT. I FILED A REPORT WITH GM. THEY DETERMINED THE PICK-UP WAS STILL SAFE TO DRIVE EVEN THOUGH THE VEHICLE HAD AUTO-SHIFTED INTO 4WD ON 3 SEPARATE OCCASIONS AND EVEN THOUGH THE 3RD TIME ALMOST GOT ME KILLED.

THE IGNITION WILL NOT TURN COMPLETELY OFF WHICH MEANS THE KEY WILL NOT COME OUT. I MAY HAVE TO RESTART THE ENGINE, PUT IT IN GEAR AND MOVE A FEW FEET, FIVE TIMES TO GET THE KEY OUT. THE ENGINE ITSELF SHUTS OFF, BUT EVERYTHING ELSE STAYS ON. THIS HAPPENS FREQUENTLY. CHEVROLET HAS ISSUED A BULLETIN SAYING A DIRTY KEY WILL CAUSE THIS. HOW MANY TIMES IN YOUR LIFETIME HAVE YOU HAD TO CLEAN A KEY? THIS HAPPENS AFTER I HAVE STOPPED AND TRIED TO TURN THE TRUCK OFF.

THE DRIVER INSTRUMENT AND RADIO DISPLAYS GO BLACK FOR SOME MINUTES (2 TO 20) MINUTES AND THEN RETURN TO FUNCTION. DURING THE BLACK OUT I CAN NOT CHECK SPEED, GAS MILEAGE, ODOMETER OR ANY OTHER INSTRUMENT FUNCTION. I HAVE VISITED CHAMPION CHEVROLET IN JOHNSON CITY, TN AND WILSON COUNTY MOTORS IN LEBANON, TN TO HAVE THE PROBLEM RESOLVED. NEITHER COULD RESOLVE THE ISSUE. THIS IS A SERIOUS SAFETY CONCERN TO ME. CAR WAS IN MOTION ON A HIGHWSY
