2018 Chevrolet Colorado Owner Complaints

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.

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.

THE DISPLAY FOR THE BACKUP CAMERA IS ON AT FULL BRIGHTNESS. THERE IS A CONTROL KNOB TO DIM THE INTERIOR LIGHTING AND DISPLAY, BUT WHEN THE VEHICLE IS PUT INTO REVERSE, THE DISPLAY GOES TO FULL BRIGHTNESS AND CANNOT BE CONTROLLED BY THE BRIGHTNESS CONTROL KNOB. AT NIGHT, THE PASSENGER SIDE MIRROR IS NOT USEABLE SINCE THE BACKUP DISPLAY IS SO BRIGHT. THIS ALMOST RESULTED IN ACCIDENTS WHEN BACKING UP INTO A PARKING SPOT.

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.

We reported issues with our thermostat to our dealer back in September of 2022. The vehicle would not defrost or heat. We were then told the thermostat required replacements but there was no part in existence and they would notify us when it became available. After following up numerous times with no actionable timeline from the dealer we consulted with a secondary mechanic who confirmed the issue was related to a thermostat sensor malfunction and would require a replacement thermostat. Again we were told that the item was not available from GM and we would be contacted when more information was available. A SPAC case was created by our dealer in October of 2022, notifying the system of the urgent need and our dealer has followed up numerous times that GM has not provided any timeline for replacement. I have also filed a separate claim in January of 2023 to GM customer service notifying them of the ongoing issue and escalating to upper management. I have not heard back on mitigation or rectification plan for our issue. This ongoing issue is a major safety concern that has rendered my vehicle unfit for operation. I am unsure why GM is not making this major safety concern a priority because we are now in the middle of a Chicago winter we’re temperatures are regularly below freezing. I cannot defrost my windows or maintain a safe cabin temperature. This is unsafe for me to operate let alone use the vehicle to transport my child because of the immediate danger it would place her and I in. I am now paying for a vehicle that has sat inoperable in my driveway for 4+ months with no end in site and opening is up to additional damages because it has had to remain inoperable for an extended period of time.

I have a 2018 Colorado 4x4 with 51K miles. Purchased with 28k. When driving at normal highway speed, get drive train shudder when increase torque is needed (hill, ramp, etc.). Only happens in overdrive. When tow/haul is activated shudder does not occur. It feels like transmission and/or drive shaft is about to fall off. I have not attempted repair due to numerous concerns voiced on this site and class action lawsuit now in progress. No warning lights or messages.

At approximately 6:15am while driving at approx 45MPH on a surface street on the right lane, I noticed an alert on the dashboard regarding the PSI of the rear driver side tire had 0 PSI of pressure and simultaneously heard the thudding sounds of a flat tire. I neither heard, nor felt any impact and there were no potholes in that section of road. I pulled over and called for roadside assistance to replace the tire with my spare. I noticed a large tear from the tread nearly all the way down to the bead along the wall of the tire. Tire M+S 255/65 R17 110T. When the tech arrived he noted the tire was new (purchase and installed 42 days earlier). I asked if he's seen this before as I hadn't, and he said he'd only seen it when a driver hit a curb, which I had not. In the early evening I took the tire back to the shop where it was purchased and before even looking at the tire they informed me I "must have hit something" and will just need to purchase a replacement. After they inspected the tire at my insistence, they concluded I must've hit something but I believe it was a case of confirmation bias. I pointed out, and they did not refute, that there was no other damage to the tire, no damage to the rim, and no damage to the vehicle. The subject tire is still in my possession and available for inspection.
