2018 Chevrolet Colorado Complaint Log

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!

I AM WRITING TO INFORM YOU OF A SAFETY ISSUE WITH MY 2018 CHEVROLET COLORADO. WHEN PUTTING THE VEHICLE IN PARK THE IGNITION KEY WILL NOT RELEASE. CHEVROLET DOC# 4811390 DOCUMENTS A FLEET WIDE PROBLEM WITH THE COLORADO. THERE HAS BEEN NO RE-CALL ISSUED BY CHEVROLET TO CORRECT THIS SAFETY ISSUE. I GOT MY COLORADO REPAIRED AT A COST OF $642.15. I LOOKED AT THE SHIFTER THAT WAS REMOVED FROM THE TRUCK, AND FOUND THAT THE MICRO SWITCH THAT ACTIVATES WHEN THE VEHICLE IS PLACED IN PARK HAD A BROKEN MOUNTING POST CAUSING IT TO BE MISALIGNED. I HAVE INCLUDED PICTURES OF THE SWITCH AND MOUNTING POST. *JS

WHILE DRIVING ON CITY STREET AND HIGHWAY, TRANSMISSION SHIFTING AT SPEEDS OF 25MPH,45MPH,55MPH START VIBRATING ALSO COMING TO A STOP FEEL LIKE A REAR END BUMP.

MY COLORADO HAS COMPLETELY SHUT DOWN/POWERED OFF WHEN MAKING A RIGHT HAND TURN. TWICE NOW. I'LL BE COMING TO A COMPLETE STOP, ACCELERATING THROUGH THE TURN AND THEN ALL OF THE SUDDEN, WITHOUT WARNING, THE TRUCK LOSES ALL POWER. NO FLASHING DASH, NOTHING. I HAVE TO COAST TO THE SHOULDER OF THE ROAD, TURN ON THE HAZARDS, PUT IN PARK, AND RESTART THE VEHICLE. THIS HAS HAPPENED TWICE NOW. FROM SOME ONLINE FORUMS I'VE READ, THE PROBLEM ONLY SEEMS TO GET WORSE AND HAS HAPPENED TO OTHERS AROUND 30-40 MPH. MY CAR IS STILL UNDER MANUFACTURING WARRANTY FOR ANOTHER 500 OR SO MILES. I TOOK MY TRUCK INTO A CERTIFIED CHEVY REPAIR SHOP AND AFTER A WEEK OF TROUBLESHOOTING AND TRYING TO RECREATE THE PROBLEM, THEY HAVE FOUND "NOTHING" WRONG WITH THE CAR. IF THIS DOESN'T GET FIXED AND CONTINUES TO OCCUR, IT'S ONLY A MATTER OF TIME BEFORE AN ACCIDENT HAPPENS.

CAB VIBRATION 70 MPH TO 75 MPH

VIBRATION AND SHUTTERING AT 40-80 MPH COMING FROM ENGINE.

MY 2018 CHEVROLET ZR2 STARTED TO HARD SHIFT BETWEEN FIRST AND SECOND GEAR. IT ALSO SOUNDS LIKE IT IS RUNNING OVER RUMBLE STRIPS WHEN DRIVING BETWEEN 50-75MPH. WHEN I RESEARCHED THIS ISSUE, I FOUND THOUSANDS OF ISSUES ONLINE THAT MATCHED THIS PROBLEM 100 PERCENT. IT IS CALLED THE CHEVY SHAKE OR THE GMC SHUTTER. MIND YOU, THE DEALERSHIP VERIFIED THAT THEY HAVE BEEN SENT KITS FROM GM TO CORRECT THESE ISSUES. IT'S CALLED THE TCC SHUDDER.

INTERMITTENT PROBLEM WITH IGNITION KEY NOT BEING ABLE TO BE REMOVED. SEEMS TO BE RELATED TO THE SHIFT LEVER, MOVING THAT BACK AND FORTH CAN USUALLY RECTIFY THE PROBLEM AFTER MANY ATTEMPTS. VEHICLE STATIONARY. *TR

IT HAS AN INTERMITTENT SHUDDER AT NO PARTICULAR SPEED AND A KIND OF TUGGING AT SLOW ACCELERATION SPEEDS, LIKE A QUICK UPSHIFT AND THEN DOWN AGAIN.

THIS STARTED ABOUT 3 MONTHS AFTER I GOT THE TRUCK AND HAS BEEN DOING IT SINCE. ON THREE SEPARATE OCCASIONS, TRUCK ENGINE SHUT OFF AFTER STOPPING THEN TURNING RIGHT ON CITY AND NEIGHBORHOOD STREETS. FIRST TIME I PULLED OUT ON A ROAD WHERE THE SPEED LIMIT IS 55 SO I WAS LUCKY NO ONE WAS BEHIND ME WHEN THE ENGINE CUT OUT. ON THE FOURTH OCCASION, TRUCK SHUT OFF AFTER BACKING UP FROM PARKING SPOT AND PUSHING ON GAS TO GO FORWARD. NO CHECK ENGINE LIGHTS, NO NOISES OR VIBRATIONS TO TELL ME TRUCK IS GOING TO SHUT OFF. I HAVE TO LOOK AT DASH TO SEE IF IT HAS GONE BLACK. RADIO STILL WORKS, AND I'M ABLE TO STEER OFF TO SIDE OFF THE ROAD BECAUSE IT'S STILL IN MOTION FROM AFTER THE TURN. I CAN PUT GEAR IN PARK POSITION, TURN KEY TO OFF, THEN START THE TRUCK LIKE NORMAL. HAVE GONE TO MECHANIC AND DEALERSHIP AND THEY CAN'T GET IT TO DUPLICATE. CHEVROLET HAS BEEN NOTIFIED BUT HAS SAID THEY CANNOT HELP IF DEALERSHIP CAN'T FIND THE PROBLEM. STEERING WHEEL ALSO STARTING TO GET STUCK IN TURN POSITION WHEN TURNING RIGHT. RIGHT AFTER THE TURN IT FEELS LIKE IT CATCHES IN SOMETHING AND I HAVE TO FORCE THE WHEEL BACK TO CENTER. STARTING TO HAPPEN ALMOST DAILY, BUT NOT FOR DEALERSHIP. I FEEL DRIVING THE TRUCK IS A SAFETY HAZARD FOR NOT ONLY ME BUT OTHERS ON THE ROAD.

TRANSMISSION HAS A SHUTTER IN IT. IT FEELS LIKE YOU ARE DRIVING ON THE ROAD EDGE WARNINGS

SOME TIME IT FEELS AS IF YOU ARE RIDING ON THE RUMBLE STRIPS ON SHOULDER OF THE ROAD AND SOME TIMES IT SHIFTS PRETTY HARD THE RUMBLE CAN HAPPEN AT ANYTIME

A FAULTY ENGINE BLOCK HEATER CAUSED THE ENGINE COMPARTMENT TO CATCH FIRE WHILE THE TRUCK WAS PARKED, TURNED OFF AND THE FACTORY INSTALLED ENGINE BLOCK HEATER WAS PLUGGED IN.

FRONT END CLUCKING WHEN GOING OVER BUMPS OR PULLING INTO DRIVEWAYS AT VEY MINIMUM SPEED.

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.

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

STEERING WHEEL CONSTANTLY SHAKES AND VEERS ON ROADWAY DEALER CHANGED TORQUE CONVERTER BUT ISSUE STILL. HAPPENS WHILE DRIVING ANYWHERE FROM 35 MPH TO 70 MPH CITY STREET OR HIGHWAY DOES NOT MAKE A DIFFERENCE FEELS LIKE STEERING CONTROL COULD BE LOST WHILE DRIVING

MY DRIVER SEAT BELT FAILS TO LOCK, IT HAS BEEN HAPPENING FOR A FEW MONTHS, BUT HAS GOTTEN DRASTICALLY WORSE. I HAVE AN APPOINTMENT WITH A DEALERSHIP, BUT THE FIRST AVAILABLE APPOINTMENT IS THURSDAY NOVEMBER 7TH 2019. I AM IN A GROUP ON FACEBOOK FOR THIS VEHICLE AND OTHERS ARE EXPERIENCING THE SAME ISSUE.

TL* THE CONTACT OWNS A 2018 CHEVROLET COLORADO. WHILE DRIVING 45 MPH, THE VEHICLE BEGAN TO SHAKE FORCEFULLY. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO HERTRICH CHEVROLET CADILLAC OF SALISBURY (LOCATED AT 2531 N SALISBURY BLVD, SALISBURY, MD 21801, (410) 713-4640) AND WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS 12,500.

TL* THE CONTACT OWNS A 2018 CHEVROLET COLORADO. WHILE DRIVING APPROXIMATELY 70 MPH, THE VEHICLE LOST POWER, DOWNSHIFTED, DECELERATED TO 20 MPH, AND THE BRAKE LIGHTS WENT OUT. THE CONTACT PULLED INTO A DITCH TO AVOID A SEMI TRUCK BEHIND HIS VEHICLE. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE CONTACT CALLED RESSLER MOTORS AT (866) 623-5535 (LOCATED AT 8474 HUFFINE LN, BOZEMAN, MT 59718) AND WAS INFORMED TO BRING THE VEHICLE TO THE SHOP. THE CONTACT STATED THAT THE VEHICLE WAS UNSAFE TO DRIVE AND NEEDED TO BE TOWED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS 19,214.

ON MULTIPLE OCCASION THE DASH CONTROLS WILL FREEZE BUTTONS WILL NOT WORK AND TOUCH SCREEN WILL NOT WORK I TOOK IT IN TO THE DEALER AND THEY TOLD ME THAT NOTHING IS WRONG WITH THE VEHICLE. BUT EVERY NOW AND AGAIN IT WILL FREEZE UP THE ONLY WAY TO GET THE CONTROL TO WORK AGAIN IS TO PULL OVER AND TURN THE VEHICLE OFF AND ON.

THE TRANSMISSION IN MY TRUCK SHAKES, SHIMMIES, VIBRATES, SHUTTERS WHEN DRIVING AND SHAKES, SHIMMIES VIBRATES EVEN AT IDLE. I TOOK THE TRUCK TO THE DEALERSHIP AND THEY REMOVED ALL OF THE TRANSMISSION FLUID AND REPLACED WITH NEW FLUID AS PER CHEVROLET CORPORATE MANDATE. THE TRUCK REMAINS IN SHAKING, SHIMMIES, SHUTTERS AND VIBRATING.

WHEN I DRIVE UP HILL THE VEHICLE STARTS TO JERK BACK AND FORTH AND HAS LOST OF POWER.

VEHICLE WAS DRIVEN AT APPROXIMATELY 20MPH AND UPPON DECELERATION THERE WAS A LOUD BANG AND ALL FOUR TIRES LOCKED UP AND HAVING NO CONTROL OVER MOVEMENT OF THE TRUCK. NO ERROR CODES FOUND AND DEALERSHIP STATES IT WAS A FAULTY TRANSFER CASE. VEHICLE HAS BEEN IN SHOP ALMOST A MONTH WILL NO RESOLUTION.

DURING SOME STARTS (IN MORNING AFTER NOT DRIVING FOR SEVERAL HOURS), THE ENGINE WILL HAVE A PULSING IDLE ~750-1000 RPM. AFTER LETTING IT SIT FOR A MINUTE TO WARM UP, I DRIVE DOWN THE ROAD. IF I AM ABLE TO DRIVE WITHOUT STOPPING, THERE WILL BE NO ISSUES. HOWEVER, IF I COME TO A STOP WITHIN 0.5 MILES OR SO, THE ENGINE WILL SHUT OFF. WHEN I TRY AND RESTART, THE ENGINE WILL STALL REPEATEDLY. THE ENGINE WILL EVENTUALLY RESTART. THERE HAVE BEEN NO CODES PRODUCED NOR ANY LIGHTS ON THE DASH BOARD. HAS HAPPENED SEVERAL TIMES.

TRANSMISSION EXHIBITS INTERMITTENT HESITATION, JERKING AND SHAKING WHEN TAKING OFF FROM A STOP AND REVERSE LURCHING WHILE AT HIGHWAY SPEEDS. THE TRANSMISSION FLUID HAS BEEN CHANGED PER THE BULLETIN WITHOUT SUCCESS. THE TRUCK HAS BEEN TO THE DEALERSHIP 4 TIMES WHERE THEY TYPICALLY REPORT "UNABLE TO DUPLICATE PROBLEM" AND THEREFORE DO NOTHING. THE LATEST COMMENT FROM GM CUSTOMER CARE WAS TO BLAME ALL THESE ISSUES ON MY TIRES (36000 MILES). LOSS OF POWER EQUALS A TIRE ISSUE?

WHEN COMING TO STOP FROM ANY SPEED THE TRUCK DOWNSHIFT HARD THAT IT FEELS LIKE YOU'VE BEEN HIT FROM BEHIND. ALSO WHEN USING REMOTE START AND YOU PUT THE KEY IN THE IGNITION AND TURN IT ON THE TRANSMISSION DOES A LITTLE JUMP LIKE THE TRUCK IS GOING INTO GEAR. WE HAVE TAKEN IT IN FOR REPAIRS 3 TIMES AND THE LAST TIME WE WERE TOLD THE ISSUE COULD NOT BE FIX AND THAT IT WAS NORMAL.

THE TORQUER CONVERTER ITS THE PROBLEM I FIND OUT A DAY ON HIGHWAY I WAS DRIVING AND THE TRUCK LOSE POWER IT TAKES TIME TO MOVE TO OTHER GEAR AND MAKE A WEIRD SOUND I TAKE THE TRUCK TO THE CHEVY DEALER AND THEY JUST FLUSH THE TRANSMISSION FLUID AND THEY SAID WILL FIX THE PROBLEM BUT AFTER THAT GET IT WORSE IT CLAPS WHEN PUT IT IN REVERSE OR DRIVE IT USE TO SHAKES WHEN YOU DRIVING EVEN AT NOT HIGH SPEED. THE PROBLEM IS NOT SOLVE AND THE GUY FROM THE DEALER TOLD ME GMC WILL NOT LET THEM CHANGE THE PART IS HIS OWN WORDS. HE SAID YOU HAVE A GOOD WARRANTY DON'T WORRY BUT I NEED SOLUTION AND THE DEALER DOESN'T SHOW ANY INTEREST TO FIX MY TRUCK PROBLEM, I HAVE TO RENT A CAR APPARENTLY WAS COVER FOR MY INSURANCE BUT A WEEK LATER THEY CALL ME BECAUSE THEY HAVE A ISSUE WITH THE CAR I RENT AND JUST RENTED FOR 24 HOURS. IS WHY I'M DOING THIS COMPLAINT TO FIND SOMEONE CAN HELP ME AND FINALLY MY TRUCK GET FIX.

THE TRANSMISSION HAS A VERY HARD DOWN SHIFT WHEN COMING TO A STOP. ALMOST FEELS LIKE YOU'VE BEEN HIT FROM BEHIND. THE FASTER YOU WERE GOING BEFORE STOPPING THE HARDER IT DOWNSHIFTS. WHEN TAKING VEHICLE IN WE WERE TOLD THERE IS NO FIX FOR THIS. ALSO WHEN USING REMOTE START ONCE YOU PUT THE KEY IN THE TRANSMISSION JUMPS. WE WERE TOLD NOT TO BRING THE TRUCK BACK FOR THIS ISSUE.

I JUST LEFT WORK, MY TRUCK WAS PARKED FOR 8, HRS. AFTER 3, MINUTES OF DRIVING THE SERVICE STABILITY TRACK LIGHT CAME ON. AFTER A COUPLE MINS. I TURNED DOWN A MAJOR HIGHWAY AND THEN THE FOLLOWING WARNING LIGHTS CAME ON: CHECK ENGINE, LOW FUEL ( IT WAS HALF FULL), TRACTION CONTROL, DRIVE WITH CAUTION, STREARING ASSIST OFF. THE ELECTRICAL PANEL WENT CRAZY AND I LOST POWER TO THE ENGINE. I PULLED OVER AND CALLED CHEVY ROADSIDE ASSIST. THEY TOWED THE TRUCK TO COX CHEVROLET, WHERE I PURCHASED THE VEHICLE BRAND NEW ONLY A YEAR AGO. THEY COULD NOT DUPLICATE THE ISSUE AND I HAD TO DRIVE IT BACK HOME. THIS IS CLEARLY A MALFUNCTION. I DO NOT FEEL SAFE DRIVING THE IT.

2018 COLORADO DEVELOPS A SHUTTER WHEN MOVING UP AN INCLINE FROM SPEEDS OF 45 TO 60 MPH ON HIGHWAYS. TRUCK HAS 33,000 MILES 10,000 MILES I PLACED ON THE TRUCK THE REMAINDER WAS WHILE THE TRUCK WAS PART OF A FLEET. JUST NOTICED THIS SHUTTER AT 32,000 MILES. THOUGH IT WAS TIRES , BUT TURNED OUT NOT TO BE THE ISSUE.

TRUCK SHAKES AT SPEEDS ABOVE 55 MPH. AT 65 MPH MY PHONE WILL FLY OFF THE MAGNET MOUNT ON THE WINDSHIELD; WATER AND ICE SHAKE AS IF BOILING AT 70 MPH AND ABOVE. SOMETIMES THE VEHICLE FEELS LIKE IT IS COMING APART IT SHAKES SO HARD. WHEN THE VEHICLE WAS TWO MONTHS OLD IT STOPPED ON A CITY STREET IN ARLINGTON VA AND WAS UNDRIVEABLE. AFTER A TIMEOUT PERIOD OF 10-15 MINUTES IT WAS DRIVEABLE BUT AT 10 MPH IT WHINED AS IF THE TRANSMISSION OR ENGINE WAS GOING TO BLOW UP. AT 20-25 MPH IT WAS A SCREAMING DEMON AND HAD TO BE TOWED TO THE DEALERSHIP (BROWNS) WHO FOUND NO RECORD IN CAR COMPUTER SYSTEM OF FAULT. BATTERY OR ELECTRICAL SYSTEM WAS COMPLETELY DEAD ON 7 JUNE 2019 WITH ABOUT 10,200 MILES. DEALERSHIP KNEW I HAD APPOINTMENT AND I ASKED FOR TOW BUT THEY DON'T PROVIDE A TOW FROM REED-LALLIER. ONSTAR WAS OF LITTLE HELP SO I CALLED MY USAA INSURANCE ROADSIDE ASSISTANCE TO GET TRUCK JUMP STARTED; I MISSED APPOINTMENT AND THEY CANCELED APPOINTMENT THAT MORNING WHICH WAS TO CHECK FOR SHAKING AND ALSO 2ND OIL CHANGE. GMCUSTOMERCARE TOOK MY CONCERNS AND ASKED MY RESOLUTION WHICH WAS CHECK BATTERY FOR BAD CELL, BE AWARE OF FIRST TRANSMISSION PROBLEM IN ARLINGTON VA AND THE CURRENT PROBLEM OF VEHICLE SHAKING. I AM A RETIRED PARATROOPER WITH VERIFIABLE SEVERE NERVE DAMAGE TO MY BACK AND LOWER LEGS AND THIS VEHICLE CAUSES SERIOUS PHYSICAL AND NEUROLOGICAL PROBLEMS WHEN DRIVING HIGHWAY SPEEDS.

AT SPEED AND ON ACCELERATION, VEHICLE PULLS INTERMITTENTLY AND SHARPLY. VEHICLE DRIVES ROUGH, TRANSMISSION SHIFTS ROUGH. TIRES SKIP UPON ACCELERATION FROM STOP. TIRES SHOW ABNORMAL TREAD WEAR ON INSIDE EDGE DESPITE PROPER INFLATION AND ALIGNMENT.

CHEVROLET COLORADO SHAKING AND SHUTTERING VIOLENTLY WHILE DRVING. EXTREMELY DANGEROUS. CHEVROLET IS NOT LISTENING TO ALL THE COMPLAINTS. ARE THEY WAITING ON A DANGEROUS DEADLY ACCIDENT BEFORE THEY ACKNOWLEDGE AND RECALL THE VEHICLE AND REPAIR THIS DANGEROUS SITUATION!

BAD RATTLING COMING FROM BACK TIRES WHEN COMING OUT OF DRIVEWAY. AND WHEN PASSING ANY BUMPS. HAS A SOUND ON LEFT TIRE THAT SOUNDS LIKE SOMETHING IS LOOSE. RATTLING SOUND IS GETTING WORST AND IT IS VERY ANNOYING. I LOVE MY TRUCK BUT I AM VERY DISAPPOINTED IN THE RATTLING SOUNDS. SOUNDS IT DID NOT MAKE WHEN I BOUGHT IT.

HAPPENED 3 TIME NOW. EACH TIME I WAS DRIVING SLOWLY, IDLING ALONG, IN PARKING LOT. EACH TIME I WAS IN GEAR (DRIVE) MOVING AT IDLING SPEED E.G. PARKING LOT CRAWL. ALL ELECTRICAL SHUTS OFF JUST LIKE I HAD TURNED THE KEY OFF. ALL LIGHTS OFF, AC OFF, RADIO OFF, ENGINE OFF, EVERYTHING OFF. NO WARNING LIGHTS, NOTHING - JUST TURNS OFF. VEHICLE RESTARTS FINE WITH NO IMMEDIATE RECURRENCE. FOR SOME REASON IT SIMPLE TURNS ITSELF OFF. IT'S GOING TO BE BAD IF THIS HAPPENS WHEN PULLING OUT INTO TRAFFIC.

THE TRUCK IS THE ZR2 MODEL, CREW CAB SHORT BED. I WAS TOWING A 2100LB TRAILER WITH 347# OF TONGUE WEIGHT AT 25MPH, UPHILL, ON A DIRT ROAD. HIT A DIP IN THE ROAD AT 25 MPH AND IT BENT THE FRAME AT THE CAB/PICK UP BOX AREA. THE FRAME NECKS DOWN TO 3 1/2 INCHES THERE WITH 2 FACTORY LARGE OVAL HOLES ON BOTH SIDES OF THE FRAME. I HAVE FOUND ANOTHER PIC OF A ZR2 TOWING A TRAILER, AND IT BENT AT THE EXACT SAME PLACE.

THE VEHICLE HAD JUST RETURNED FROM A 50 MILE TRIP WHEN THE VEHICLE WAS PARKED. THE VEHICLE WAS NOT RUNNING AND HAD BEEN PARKED FOR ABOUT 5 MINUTES WHEN THE FIRE STARTED (FROM THE ENGINE COMPARTMENT).

THE VEHICLE HAD JUST DRIVEN BACK FROM A 50 MILE DRIVE AND WAS THEN PARKED. THE VEHICLE WAS NOT RUNNING AND HAD BEEN PARKED FOR ABOUT 5 MINUTES WHEN A VEHICLE FIRE OCCURRED (STARTING IN THE ENGINE COMPARTMENT).

HARD SHIFTING WHEN YOU ACCELERATE IN THE FIRST TWO GEAR AND HARD DOWNSHIFTING WHEN STOPPING.

WHILE THE VEHICLE IS IN MOTION I GET E RATTLE THOUGHT MY STEERING COLUMN DOWN INTO MY PEDDLE,. I CANN FELL THE RATTLE THROUGH THE INTERMEDIATE STEERING SHAFT. IT HAPPENS ALOT MORE ON ROUGH ROADS, FOR EXAMPLE MY DRIVE WAY IS GRAVEL, EVERYTIME I COME HOME INTO MY DRIVEWAY I FEEL THE RATTLE. IT DOESN'T FEEL LIKE MY TIRES, BUR MORE SO MY WHOLE STEERING SHAFT. YOU CAN ALSO SEE THE SHAKE IN THE STEERING WHEEL IF YOU LOOK CLOSELY AT IT. I HAVE ADDRESSED THIS WITH MY DEALERSHIP AND TOLD THEM I DON'T FEEL COMFORTABLE DRIVING IT. BUT THEY TOLD ME THEY COULDN'T RECREATE THE NOSIE SO THEY COULDN'T EVEN CHECK THE STEERING SHAFT FOR ME. I DON'T FEEL SAFE. AND I WANT A RECALL FOR THIS.

HARD/ROUGH SHIFTING UP IN GEARS AND SAME DOWN SHIFTING IN GEARS. SHAKING/JERKING/SHUDDERING AT SPEEDS APX. 20-70 MPH. TRANSMISSION CAN DOWN SHIFT SO HARD, AT TIMES, IT FEELS LIKE SOMEONE HIT YOUR FROM BEHIND. WANTS TO STALL/SLIP SHIFTING UP IN GEARS. SEEMS TO HAVE TOO MUCH FREE PLAY IN DRIVELINE WHILE SITTING STILL SHIFTING FROM DRIVE TO REVERSE. MAKES A CLUNK SOUND.

CHEVROLET MONTEBELLO DELEARSHIP IN CALIFORNIA REFUSED TO DO ANY WORK ON OUR 2018 CHEVROLET COLORADO. WE RECEIVED A LETTER ABOUT A RECALL ON THE AIRBAGS OF THE TRUCK AND WE TOOK THE TRUCK IN DUE TO SOME ISSUES ON THE TRUCK AND THE RECALL. BECAUSE THEY FELT THE VEHICLE WAS TAMPERED WITH THEY DENIED TO DO ANY WORK ON THE TRUCK EVEN THE RECALL OF THE AIRBAGS!!!!! THE SERVICE TECHNICIAN WE WERE WORKING WITH SAID THEY WERE NOT GOING TO DEAL WITH US ANYMORE BC I MADE A COMPLAINT TO GM AND I WOULD NEED TO DEAL WITH THEM DIRECTLY THEY REFUSED TO PROVIDE ME ANY DOCUMENTATION EVEN AFTER THEIR SERVICE MANAGER SAID THEY WOULD. THIS IS NOT ACCEPTABLE FOR THEM TO REFUSE TO FIX SUCH A MAJOR SAFETY CONCERN AND TO BE HONEST THEY ARE BEING NEGLECTFUL AND SHOULD BE HELD ACCOUNTABLE FOR BEING SO UNETHICAL.

SHUTTERS AND SHAKES FOR LONG PERIODS WHILE DRIVING. GROWLS AND MAKES A LOW RUMBLING WHILE SHAKING THE ENTIRE TRUCK. DURING THIS VIBRATION WHICH HAPPENS ALL THE TIME ITS HARD TO HEAR THE PERSON TALKING NEXT TO YOU OR THE RADIO IF ITS ON LOW. TOOK TO DEALER AND THEY SAID THEY ALL DO THAT; IT'S COMMON WITH THESE; NOTHING TO DO.

NOTICED A "SHUDDERING" IN THE TRANSMISSION DURING LIGHT ACCELERATION BETWEEN 40-60MPH AROUND 1500RPM. WHOLE TRUCK VIBRATES LIKE YOU ARE DRIVING OVER RUMBLE STRIPS. ONLY 4150 MILES ON THE TRUCK!

TAKATA RECALLS HEAR WATER RUSH WITH A GURGLE NOISE FROM DASHBOARD THIS HAPPENS WHEN TAKING OFF FROM A STOP. ALSO WHEN THE VEHICLE IS IN DRIVE WITH THE FOOT ON THE BRAKES IT MAKES LOUD NOISE THEN JUMPS. ALSO PAINT ON HOOD HAS FISHEYES THE TRUCK ALSO IDOLS HIGH WHEN STARTING UP.

PURCHASED NEW CHEVY COLORADO 4X4 EXTENDED CAB WITH 3.6-LITER V6, TRANSMISSION 8-SPEED MODEL 8L45. TRANSMISSION DEVELOPED SHUDDER DURING LIGHT THROTTLE ACCELERATION BETWEEN 30 AND 70 MPH.
