2018 Chevrolet Colorado complaints

2018 CHEVROLET Colorado...when driving if a side window is dropped less than an inch, vehicle shakes, vibrates and make odd noises. Raise all windows and vehicle runs smoothly. Many drivers are reporting the same problem online. Both the Colorado and same GMC vehicle having same problem. When a window is lowered the vehicle vibrates and shakes violently...one has to drop down to 30 miles and hour to make it safe to drive. Seems like a problem GMC should be able to repair without much trouble.

The Multimatic DSSV damper in the left rear lost its fluid through a leak. Various forums indicate there is a design flaw with the DSSV for the ZR2. A blown shock renders the vehicle unbalanced, and marginally safe in unexpected rough terrain or when pulling a trailer. These dampers or shocks have shafts that are too thin and poorly designed seals, causing them to leak.

Ignition tumbler and steering wheel locked. Could not turn key, could not turn wheel. Truck was is park on flat driveway. Tried all basic instructions (three adults) and then called mobile mechanic. He could not get it to turn either and could not remove steering wheel cover to access ignition tumbler to replace. Truck is three years old. Had to have it towed to dealership.

IGNITION SWITCH FULLY WON'T TURN TO OFF POSITION. ENGINE DOES TURN OFF, BUT KEY CAN'T BE REMOVED. HAPPENS FREQUENTLY AND SO FAR, STARTING IT, PUTTING IT INTO DRIVE OR REVERSE AND MOVE A BIT, THEN BACK INTO PARK WILL WORK. AT SOME THAT MIGHT NOT WORK AND I'D HAVE TO LEAVE THE KEY IN THE IGNITION AND LEAVE THE TRUCK UNATTENDED. I COULD STILL LOCK IT, BUT IF SOME KIDS SEE IT OR BREAK INTO IT, THEY COULD DRIVE IT AWAY. CHEVY KNOWS ABOUT THIS. THERE IS A SERVICE BULLETIN #PI1429B.

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.

2018 CHEVY COLORADO ZR2, 21000 MILES. ENGINE SHUT DOWN WHILE DRIVING IN MOTION ON ROAD. RESTARTED TWICE AND SHUTDOWN AGAIN TWICE. CHECK END ENGINE LIGHT CAME ON AND TRACTION CONTROL SAID IT WAS DISABLED. STARTED THIRD TIME AND PUT IN DRIVE. WOULDN'T PUT POWER FROM ENGINE TO DRIVE TRAIN. 4TH START, PUT IN DRIVE AND LIMPED BACK HOME. WAS TOWED TO CLOSEST DEALER AND THEY CLEARED ERROR CODES WITH DIAGNOSING. I SCANNED CODES BEFORE BEING TOWED AND ERROR CODES WERE U0700 AND U0100. AFTER 3 DAYS OF NO COMMS FROM 1ST DEALER HAD 2ND DEALER PICK UP VIA TOW TRUCK. THEY SAID 1ST DEALER CLEARED CODES AND COULD NOT DUPLICATE. PICKED UP TRUCK AND RAN FINE FOR A WEEK, THEN HAD SAME ISSUE ON BUSY ROAD. HAD TO RESTART, ENGINE LIGHT CAME ON AND LIMPED BACK HOME. SCANNED CODES AND RECEIVED SAME U0700, U0100. DEALER IS HAVING TOW TRUCK PICK UP TRUCK TO DIAGNOSE AND REPAIR. THIS IS A SERIOUS ISSUE CAUSING TRUCK TO SHUT OFF WHILE DRIVING AND NOT KNOWING IF IT WILL RESTART AND HAVE POWER TO DRIVETRAIN.

STARTED THE TRUCK ON A COLD MORNING, COOLING FAN KICKED IN ON HIGH WITHIN SECONDS OF START. TEMPERATURE GAUGE ON DASH NOTED TO BE INOPERATIVE AT THAT TIME. HOSES FROM RADIATOR BECAME WARM AS NORMAL, HEAT DELIVERY TO CAB ALSO NORMAL. DROVE FOR A FEW MILES WITHOUT CHANGE IN FAN SPEED. ENGINE TURNED OFF, FAN SPEED REMAINED HIGH FOR SEVERAL MINUTES. SAME PATTERN OCCURRED INTERMITTENTLY, WITH NORMAL FUNCTION OTHERWISE, INCLUDING NORMAL FUNCTION OF DASH TEMPERATURE GAUGE. CODES READ AT REPAIR SHOP DURING ONE EPISODE SHOWED PROBLEM WITH THERMOSTAT. THERMOSTAT/HOUSING REPLACED ON 2/15/21. TRUCK DRIVEN SEVERAL TIMES WITHOUT PROBLEM, BUT SEVERAL DAYS LATER, PROBLEM OCCURRED AGAIN, FAN ON HIGH, TEMP GAUGE INOPERATIVE. HAS BEEN INTERMITTENT SINCE, WITH NORMAL FUNCTION IN BETWEEN IDENTICAL MALFUNCTION EPISODES.

DUEL DRINK (COFFEE) CUP HOLDERS NEXT TO SHIFTER LEAK FROM ANY DRIP OR SPILL. IT IS NOT DESIGNED TO CONTAIN ANY SMALL OR INSIGNIFICANT SPILL OR DRIP. ANY LIQUID LEAKS DOWN DIRECTLY UPON SENSITIVE EXPOSED ELECTRICAL DIP SWITCHES NEEDED TO SHIFT THE TRUCK. THIS INCLUDES THE RUBBER RESERVOIR (DOES NOT HOLD WATER AND DIRECTS LIQUIDS THROUGH KNOBBIES TO UNDERSIDE) AND THE HARD PLASTIC CONTAINER (HARD PLASTIC COMPARTMENT HAS DRAINAGE HOLES THAT LEAD DIRECTLY TO TOP OF ELECTRICAL SWITCHES) IS DESIGNED LIKE A STRAINER. REPLACING ELECTRICAL SWITCHES COST ME $632. I CANNOT USE THE BEVERAGE HOLDERS AS I INFERRED THAT THEY WERE DESIGNED TO USE, TO NOT ONLY HOLD MY BEVERAGE IN PLACE BUT CONTAIN IT FROM LEAKING ABOVE ANY SENSITIVE EXPOSED ELECTRICAL SWITCHES. I UNDERSTAND THE SAME DESIGN IS IN THE CHEVY EQUINOX THIS YEAR. GOOD LUCK.

WE WERE DRIVING ON A CITY STREET AND WE STARTED TO SMELL BURNED PLASTIC, WE PULLED OVER AND THE SEAT WHERE MY 3 MONTH OLD BABY IN HER CAR SEAT STARTED TO SMOKE, I IMMEDIATELY TOOK THE CAR SEAT OUT AND FLAMES STARTED TO COME OUT FROM BEHIND THE SEAT, POLICE AND FIRE DEPARTMENT CAME AND EXTINGUISHED THE FIRE, FIRE DEPARTMENT TOLD ME IT'S A ELECTRICAL RELATED FIRE.THEY ARE NO SEAT WARMERS ON THE REAR SEATS.

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

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

WHEN TURNING THE KEY INTO THE IGNITION POSITION THE VEHICLE WILL GIVE A RANDOM DOWNSHIFT UNLESS THE BRAKE PEDAL IS PRESSED DOWN. ALSO EXPERIENCING A ROUGH DOWNSHIFT BETWEEN 2ND AND 1ST GEAR WHEN STOPPING AS SMOOTHLY AS POSSIBLE. VEHICLE AS BEEN IN AND OUT THE DEALERSHIP WITH THE PROBLEM STILL EXISTING.

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.

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.

THE TRUCK VIBRATES , STUTTERS SOME TIMES WHEN DRIVING. WENT TO DEALER HE SAID IT HAS BEEN HAPPENING IN TRUCKS. HE SAID THICKER TRANS OIL SHOULD FIX IT. IS THIS JUST A BAND AID FOR A BIGGER PROBLEM. WOULD LIKE YOUR VIEW. THANKS.

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

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

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.

TL* THE CONTACT OWNS A 2018 CHEVROLET COLORADO. THE CONTACT STATED THAT THE HOOD BOUNCED UP AND DOWN WHILE DRIVING AT VARIOUS SPEEDS WITHOUT WARNING. THE CONTACT INITIALLY TOOK THE VEHICLE TO JEFF GORDON CHEVROLET (228 S COLLEGE RD, WILMINGTON, NC 28403) WHERE THEY ADJUSTED THE HOOD LATCH BUT THE FAILURE PERSISTED. THE CONTACT THEN TOOK THE VEHICLE TO OCEAN CITY CHEVROLET (2366 OCEAN HWY W, SHALLOTTE, NC 28459) WHERE THEY WERE UNABLE TO DUPLICATE THE FAILURE. THE MANUFACTURER WAS THEN NOTIFIED OF THE FAILURE AND A CASE WAS FILED. SHE WAS THEN INFORMED THAT SHE WOULD BE CALLED BACK FOR AN UPDATE. SINCE THE INITIAL CONVERSATION, THE CONTACT HAD NOT HEARD BACK FROM THE MANUFACTURER AND HAD BEEN UNABLE IN REACHING THE MANUFACTURER. THE VEHICLE HAD YET TO BE REPAIRED. THE FAILURE MILEAGE WAS 3,901. *BF *AS

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.

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.

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

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.

TRANSMISSION SHUDDERING. - IDENTIFIED VARIABLE SPEED OCCURRENCE COULD HAPPEN AT 25 OR 65. UNRELATED TO TIRES/STEERING OR TO SHOCK CAVITATION OR ROUGH ROADS. HAPPENS ON SMOOTH OR ROUGH ROADS. VEHICLE HAS NOT BEEN OFF-ROAD. VARIED INCONSISTENCY. MORE APPARENT WHEN ENGINE IS COLD SHIFTING FROM 1ST TO 2ND TO 3RD THEN WILL DISSIPATE. SHIFTS HARD 1ST TO 2ND AND SOMETIMES 3RD WHEN ENGINE IS COLD. ONCE WARM SHIFTING IS SMOOTHER BUT SHUDDERING STILL OCCURS.

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

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

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.

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

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.

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.

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.

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.

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

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.

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.

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.

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.

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?

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.

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.

TRANSMISSION HAS HORRIBLE SHIFTING. HARD SHIFTING AT LOW SPEEDS AND WHEN DECELERATING (FEELS LIKE I WAS REAR ENDED). TORQUE CONVERTER WAS REPLACED. FROM LOW SPEED, IT DOESN'T DOWNSHIFT TO ACCELERATE UNLESS THE PEDAL IS FLOORED. ALSO, THERE IS HESITATION/PEDAL LAG FROM A STANDSTILL, WHICH MAKES IT UNPREDICTABLE WHEN TRYING TO PULL INTO TRAFFIC. THAT PART IS A REAL SAFETY CONVERN.

TL* THE CONTACT OWNS A 2018 CHEVROLET COLORADO. THE CONTACT STATED THAT THE DRIVER AND PASSENGER SIDES OF THE FENDER WHEEL/CARGO BED WERE BUCKLING AND RIPPLING. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO ALL AMERICAN CHEVROLET OF SAN ANGELO (203 NORTH BRYANT BLVD, SAN ANGELO, TX 76903, 844-342-6320), BUT WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS CONTACTED AND PROVIDED CASE NUMBER: 95019035528. NO FURTHER ASSISTANCE WAS PROVIDED. THE FAILURE MILEAGE WAS 69,000.

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.

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.

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.
