  The Stibilitrack in the truck went out just after 20 minutes of driving in 34 degree rainy weather at 65 mph. Found out that it was the passenger front bearing reluctor had chipped away, which is what the wheel speed sensor reads. Once one those go out, you lose Stibilitrack and ABS. I believe that this is a significant safety issue, and a poorly engineered/designed system. The rear system reads gear which is what should be in the front should have as well, not a "magnetic ring". This should be fixed so that noone gets injured or killed. It's also a waste of consumer money that you have to change out an entire wheel bearing hub assembly to fix the issue. Shame on the company. In the photos, notice that half the black ring (the reluctor) is missing.

  A/c lines near driver side wheel well has chafed through fuel line and wire harness.Causing a couple thousand dollars in damage.Nor warning indicators leading up to either incidents. My chevy dealership mis diagnosed it twice and has now found the issue. Fuel lines leak can cause fires and as far as the electrical issue I've been left stranded with my 3 year old daughter a couple of times..Have looked up forums and many people have had the same issue.

  He wiring harness to the 4wd kept coming on which wouldn’t allow me to ingage. Mountain Chevy citified mechanic found a chafing on the wiring harness. After filing it my truck started to light up like a Christmas tree, Stability service, trailer brake service, Locker service, Power streering service and they done turn off. Which is caused by more chafing wires that are to close to components of the engine bay getting to hot. Now my power steering turns off and when driving the truck it kicks on and make me loose control of the vehicle. Big diffect on Chevys manufacturing this vehicle. I’m not able to drive it and now they keep telling me that they don’t have the part or can’t find it.

  Electrical problems with Chevrolet Mylink display. A variety of errors include backup camera flashing on at highway speeds, hands free phone calls put on hold, navigation screen flashing random inaccurate destinations. These distractions impair safe operation of the vehicle. Dealer verified issues but could not perform diagnostics on a timely basis. Issues continue.

  ABOUT A YEAR AGO, I STARTED GETTING A SLIGHT SHUDDER IN MY TRANSMISSION SO I TOOK IT TO THE DEALER FOR REPAIR. THEY COULDN'T GET IT TO SHUDDER. SEVERAL TIMES I'LL BE DRIVING DOWN THE ROAD AT OR AROUND 45MPH AND THE TRUCK WILL START SHUDDERING SO BAD I FEEL LIKE I HAVE TO PULL OFF THE ROAD. EVERY TIME I TAKE IT TO THE DEALER FOR REPAIR I END UP LOSING MY TRUCK FOR A DAY AND THEY TELL ME THEY CAN FIND ANYTHING WRONG EVEN THOUGH THIS IS A KNOWN ISSUE AND THERE IS A TSB OUT TO FIX THE ISSUE.

• 12/04/2022· POWER TRAIN

  My 2018 Colorado Z71 (40,000 miles) suffers from transmission shudder intermittently. Dealer took it for a 14 mile test drive and was unable to duplicate. Blamed it on the tires. Refused to flush transmission fluid in accordance with GM TSB 18-NA-355. Shudder becomes worse when trailering boat. Known issue to GM, however, dealers refuse to perform the solution provided by GM in the absence of a recall.

• 12/01/2024· EXTERIOR LIGHTING

  Rear back up camera at night is extremely bright and blinding to driver. Makes it useless at night and dangerous. There's no way to lower brightness setting for night time back up moves. I've seen many complaints on this. We owners shouldn't have to pay to have this fix.

  BRAND NEW 2018 MIDNIGHT EDITION CHEVY COLORADO LESS THAN 24HRS ON THE ENGINE AND HAD LESS THAN 900 MILES ON IT. WENT TO GO TO WORK ONE MORNING AND IT WOULDN'T DO ANYTHING. NO REVERE. NO POWER STEERING. ALL LIGHTS AND GAUGES WERE FLICKERING AND GOING CRAZY. ENGINE WAS CHUGGING AND MAKING ODD NOISES.IT WOULD NOT MOVE FROM MY GARAGE/DRIVEWAY. HAD IT TOWED IT TO NEAREST DEALERSHIP. OVER 2 WEEKS OF DIAGNOSTICS IT'S EITHER A STEERING MODULE OR A WIRING HARNESS PART. DEALERSHIP TELLS US ITS FAULTY WIRING/STEERING MODULE. IT IS AN INTERMITTENT ISSUE AND IT'S HARD TO DIAGNOSE. I REALLY FEEL THAT THIS COULD CAUSE MANY SAFETY ISSUES SINCE POWER STEERING WAS COMPLETELY OUT AND IT WANTED TO SHUT OFF ON US. THIS COULD HAVE BEEN BAD IF IT HAPPENED WHILE WE WERE DRIVING IT TO WORK. THE DEALERSHIP WE PURCHASED IT FROM HAD DONE SOME ELECTRICAL WORK BUT DID NOT DISCLOSE WHAT WAS DONE UNTIL IT QUIT WORKING AND WAS BROUGHT TO A DIFFERENT DEALERSHIP. THEY BROUGHT IT TO OUR ATTENTION WHEN IT WAS TOWED IN. THE WIRING THAT WAS DONE BEFORE PURCHASE IS WHAT'S CAUSING ALL ISSUES ELECTRONICALLY. TRUCK IS CURRENTLY IN THE SHOP WAITING FOR A PART THAT IS ON BACKORDER. WAITING FOR PAPERWORK AFTER REPAIRS ARE COMPLETED. IF THEY CAN BE COMPLETED. THEY'RE STILL TRYING TO FULLY UNDERSTAND THE ELECTRICAL ISSUES SINCE IT IS SO RANDOM. IT HAS BEEN IN THEIR SHOP FOR OVER 2 WEEKS NOW. I JUST WANT SOMEONE TO BE AWARE OF THESE ISSUES INCASE IT NEEDS TO BE RECALLED. THIS COULD BE A SCARY ISSUE IF IT HAPPENS WHILE DRIVING.

• 11/18/2018· POWER TRAIN,ENGINE

  I HAVE A 2018 CHEVROLET COLORADO LT 4WD CREW CAB. MULTIPLE TIMES ON A COLD START THE ENGINE IS MISFIRING. THE CHECK ENGINE LIKE COMES ON, THE VSA, AND T/C LIGHTS ALL COME ON AND A NOTIFICATION ON THE DASH SAYING STABILITRAK IS DISABLED. THE VEHICLE SHAKES TERRIBLY. THE CHECK ENGINE LIGHT WILL FLASH AND THEN GO SOLID. I AM AN AUTOMOTIVE TECHNICIAN. I KNOW THAT A MISFIRE SHOULD SET A HARD DTC. WHEN THE VEHICLE IS TURNED OFF AND STARTED SEVERAL HOURS LATER THERE IS NO CHECK ENGINE LIGHT OR ANY OTHER LIGHT ON. THE DEALERSHIP IN MARYSVILLE, OH HAD MY TRUCK FOR 3 DAYS AND TOLD ME THEY CLEANED A BUNCH OF TERMINALS AT SEVERAL CONNECTORS. WHATEVER THAT IS SUPPOSED TO DO. THEY SAID THEY STARTED THE VEHICLE SEVERAL TIMES AFTER AND EVERYTHING WAS GOOD. THE NEXT DAY AFTER I PICKED THE TRUCK UP, IT DID THE SAME EXACT THING! EXTREMELY FRUSTRATING! I KNOW A CONTINUOUS MISFIRE LET'S UNBURNED FUEL INTO THE CATALYTIC CONVERTER WHICH LEADS TO PREMATURE BREAKDOWN OF THE CATALYST. SO MY QUESTION IS WHAT IS BEING DONE ABOUT THESE ISSUES? ANOTHER ISSUE IS WITH THE TRANSMISSION. ON A COLD START THERE IS A CLUNK NOISE. THEN WHEN YOU ARE DRIVING AT CRUISING SPEED AND YOU LET OFF THE THROTTLE AND DEPRESS THROTTLE AGAIN THERE IS A SHUDDER. ALSO, WHEN YOU COME TO A COMPLETE STOP THE VEHICLE TRIES TO JOLT FORWARD. THIS IS EXTREMELY CONCERNING ESPECIALLY ON A VEHICLE WITH ROUGHLY 18,000 MILES ON IT. THIS NEEDS TO BE ADDRESSED PROMPTLY!!

  THE TRUCK'S DRIVETRAIN/TRANSMISSION CONSTANTLY SHAKES, SHUTTERS WHILE DRIVING. IT HAPPENS PERIODICALLY THROUGHOUT THE RPM RANGES.

• 11/13/2025· POWER TRAIN

  Highlighting a materials defect with the rear crankshaft reluctor ring on the 2.8 LWN Duramax, installed in the Army Infantry Squad Vehicle and the 2015-2023 Chevrolet Colorado, from which it is based. When the ring delaminates, due to age, the vehicle engine shuts off and no start, rendered dead lined, as the ECU can no longer "see" the crank position. Requiring the transmission to be removed to rectify the issue.  I was pulling a trailer up a hill on the freeway when my truck down shifted, in an effort to slow down for a bus that was merging unexpectedly and the truck died at speed. The increase in RPM initiated an unplanned, instant disassembly of the ring due to cracking on the material and increased centrifugal force, shutting off the engine without warning, at speed. Again, just dead stick to the shoulder, towing a trailer, on the freeway. That could have been bad... Had truck towed to GM dealer, for a month-long repair.

• 11/08/2019· STEERING

  WHILE DRIVING, SPECIFICALLY WHEN MAKING TURNS AT VARIOUS SPEEDS, THE STEERING WHEEL WOULD GET JAMMED UP AND BE ALMOST IMPOSSIBLE TO TURN BACK TO COMPLETE A TURN/GET STRAIGHTENED OUT. HAPPENS ON BOTH LEFT AND RIGHT TURNS. FIRST HAPPENED ABOUT 2 WEEKS AGO, JUST ONE TIME WHILE EXITING MY DRIVEWAY. I TURNED THE ENGINE OFF AND BACK ON AND IT SEEMED TO GO AWAY. IT IS NOW VERY CLEAR THAT IT IS MECHANICAL IN NATURE, SOMEWHERE CLOSE TO THE STEERING WHEEL IN THE CONSOLE. I HAVE AN APPOINTMENT NEXT WEEK WITH THE DEALERSHIP, I WILL UPDATE WITH THE FINDINGS.

  I HAD TRUCK STATIONARY PARKED ON A SLIGHT INCLINE ON A DIRT ROAD FOR ABOUT 5 MINUTES WHEN I HEARD A ODD SOUND LIKE "ARRRRR CLUNK" AND MY CAR ROLLED DOWN A HILL. I HAD MY CAR ON PARK WHILE ON 4LOW WITH THE ENGINE OFF. I DID NOT HAVE MY PARKING BRAKE ON THOUGH BUT THE INCLINE WAS SO SLIGHT I FEEL I DID NOT NEED IT. MY TRUCK WAS NOT LOADED WITH ANY EXTRA WEIGHT OR ANYTHING TO CAUSE IT TO ROLL DOWN THE HILL. I TRULY BELIEVE I AM NOT AT FAULT FOR THIS HAPPENING IT IS A BRAND NEW CAR HOW COULD THIS HAPPEN? PRIOR TO THIS I WAS NOT DOING ANYTHING EXTREME TO DAMAGE MY CAR IN ANY WAY. SOMETHING MUST HAVE FAILED ON MY TRUCK.

• 11/05/2024· FUEL/PROPULSION SYSTEM

  I detected the smell of fuel while the vehicle when it was both not running and running. I brought the truck to Banks Chevrolet in Concord NH. The high pressure fuel pump detached from its mounting flange, resulting in damage to the attaching high pressure fuel pipe causing a constant fuel leak. Dealer replaced the high pressure fuel pump and high pressure fuel pipe to resolve the concern. There is a NHTSA recall that my vehicle should have been included in, 18V358000. The GM recall number is 18188. I paid out of pocket (~$1500) to fix this safety issue when it should have been fixed initially with the recall.

  I HAVE A 2018 CHEVROLET COLORADO 3.6L. I HAVE HAD A RATTLE NOISE ON COLD START THAT WOULD HAPPEN EVERY SO OFTEN. NOW THAT I'M 1K MILES OUT OF POWERTRAIN WARRANTY THIS RATTLE NOISE HAPPENS JUST ABOUT EVERY TIME I START MY TRUCK. IT IS CAUSED BY THE VARIABLE TIMING ACTUATOR ON THE CAMSHAFT. I AM AN AUTOMOTIVE TECHNICIAN, AND I'M VERY FAMILIAR WITH VARIABLE TIMING ACTUATORS. THE PROBLEM IS THE LOCK PIN IN THE ACTUATOR DOES NOT FUNCTION PROPERLY WHEN YOU TURN THE VEHICLE OFF CAUSING IT TO DRAIN ALL THE OIL OUT OF IT. THIS CAUSES THE ACTUATOR TO RATTLE AROUND UNTIL IT GET OIL PRESSURE. THIS WILL EVENTUALLY CAUSING ISSUES WITH YOUR TIMING CHAIN AND OTHER COMPONENTS INTERNALLY IN THE ENGINE. VERY DISTURBING THAT GM KEEPS MAKING VEHICLES THAT WORK FINE, USUALLY, UNTIL THEY HAVE GOTTEN OUT OF WARRANTY. LET ME ALSO STATE THAT I REGULARLY CHANGE MY OIL WITH THE RECOMMENDED OIL AND WELL BEFORE IT'S DUE. NOT VERY HAPPY!

  All the sensors seem to not be functioning correctly. Doesn't tell me the right measurements for the wheels, gas, over heating. Right front passenger door locks/unlocks when it wants. It chokes up when trying to accelerate. Theres a rattling noise that comes from under the car. First time I took it to the dealership, they stated it was a bolt that had come loose on the exhaust pipe. They placed a new one which lasted a year and a half and now its back to making the noise. I took it again to the dealership, this time they claimed they couldn't find anything. My airbag sensor keeps coming on constantly. My fuel sensor claims 116 miles one moments and 5 or 6 minutes later, it says I have 50 miles. My car was over heating and low on Anti-freeze, the car never notified it was over heating.

• 10/20/2023· STEERING

  While driving my 2018 Chevy Colorado with 42000 miles I noticed my vehicles steering would get stuck while making turns on the highway and local streets. The problem was intermittent and was getting worse. I didn't receive any warning lights or codes for this problem but realized I had to bring it to a Chevy dealer to try to resolve the issue because I was afraid to drive it any longer due to steering possibly locking up completely. The mechanic at Island Chevy in Staten Island said the electronic rack and pinion steering gear failed and I had to replace with a new one. The cost of the repair was $2700 dollars. I was very shocked by the price due to age of car, the low mileage and never doing any off road driving. I did have another mechanic look at this problem before Chevy did and couldn't pinpoint the exact issue at the time I brought it in. The mechanic told me to bring it to Chevy to hopefully pinpoint the problem and see if there were any recalls or warranties on it.

• 08/24/2023· POWER TRAIN

  While driving, there is noticeable “shudder” that seems to feel like an issue with the transmission when it is shifting (automatic transmission). Research online shows this to be a consistent issue and concern with many owners of the 2018 Chevy Colorado. Having this shudder has not had a solution by the several mechanic shops I’ve been to. Nobody seems to know what is causing this issue, but with many owners having this same problem there must be something that Chevrolet can do to resolve this issue. We bought the vehicle brand new in 2018, and it is now paid off, but this shudder while driving has happened since we have owned the vehicle. It seems to be more prevalent while driving between 30 mph to 60 mph. The shudder happens during ever drive we take. We have the vehicle maintenance performed on all of the recommended intervals for oil, fluids, tires, brakes, etc. This is definitely something that should be a recall.
