2005 Chevrolet Cobalt Powertrain & Transmission Problems

WHILE DRIVING THROUGH AN INTERSECTION CAR SHUT OFF. THIS LOSS OF POWER WHILE DRIVING HAS HAPPENED SEVERAL TIMES OVER THE LAST FEW MONTHS. I CALLED CHEVY DEALERSHIP TODAY AND WAS NOTIFIED IGNITION SWITCH WAS ALREADY REPAIRED PREVIOUSLY AND THAT I MAY BE CHARGED A DIAGNOSTIC FEE IF I BRING THE CAR IN FOR REPAIR.

TRACTION CONTROL WARNING LIGHT CAME ON AFTER STARTING VEHICLE. SHIFTED FROM P TO R AND THE SHIFT WAS HARD. SHIFTED TO D AND A CLUNK OCCURRED. VEHICLE DID NOT DRIVE CORRECTLY. SHUT OFF VEHICLE AND STARTED IT AGAIN. PROBLEM WENT AWAY. THIS COULD BE VERY DANGEROUS IF IT HAPPENS WHILE DRIVING AT SPEED.

VEHICLE WOULDN'T START. LIKE THE BATTERY WAS DEAD, WOULDN'T EVEN TRY TO TURN OVER. GO TO TURN THE KEY OFF AND POP MY TRUNK WHERE THE BATTERY IS LOCATED AND I CAN NOT GET MY KEY TO TURN ALL THE WAY BACK TO THE OFF POSITION, AS A RESULT I CANNOT REMOVE MY KEY. THE SPEEDOMETER READ 30MPH EVEN THOUGH THE VEHICLE NEVER STARTED AND WASN'T MOVING. NON OF THE ELECTRONICS WERE WORKING SO I WAS UNABLE TO POP MY TRUNK. THIS HAS HAPPENED SEVERAL TIMES BEFORE AND EVENTUALLY THE VEHICLE WILL START AND WHEN IT DOES THE BATTERY LIGHT STAYS ON AND THE DASH READS; ENGINE PERFORMANCE LOW. THE TRANSMISSION WILL SURGE AS I AM DRIVING AND I CANNOT GO FASTER THAN 30MPH. I HAVE EVEN HAD THE CAR SHUT OFF COMPLETLY WHILE I WAS DRIVING DOWN THE ROAD. AFTER ANYWHERE BETWEEN A FEW HOURS TO A FEW WEEKS THE VEHICLE WILL STOP ACTING UP AND DRIVE NORMAL FOR A WHILE. AGIAN THE NORMAL LASTS ANYWHERE BETWEEN A FEW HOURS TO A FEW MONTHS AS WELL. THE POWER STERING ALSO FLASHES ON THE DASH AND SOMETIMES CUTS COMPLEATLY OUT.

CAR ALARMS POWER STEERING DISPLAY COMES ON, CAR SHAKES, WON'T SHIFT GEARS, WAS LOOKED AT , COMP SAID LOST CONNECTION TO TMC TRANS MODULAR CONTROL. WHILE IN MOTION

TL* THE CONTACT OWNS A 2005 CHEVROLET COBALT. WHILE THE VEHICLE WAS STATIONARY, THE IGNITION KEY BECAME STUCK IN THE VEHICLE. ON ANOTHER OCCASION, THE VEHICLE STALLED WITHOUT WARNING. THE CONTACT STATED THAT THE VEHICLE FAILED TO SHIFT INTO THE REVERSE GEAR. IN ADDITION, THE VEHICLE WOULD NOT START WHEN PROMPTED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 158,000. THE VIN WAS UNAVAILABLE.

WHILE DRIVING IN TOWN SHORTLY AFTER TURNING ONTO A 45 MPH ROAD MY VEHICLE, AUTOMATIC, STARTED HESITATING WHILE SHIFTING INTO THE NEXT GEAR. IT WOULD SHIFT BUT NOT LIKE NORMAL. BROUGHT IT INTO A REPAIR SHOP TO HAVE A DIAGNOSTIC RAN TO BE INFORMED IT IS A FAILURE TO COMMUNICATE WITH TCM. CODE U0101 AND ALSO U2100. AFTER DOING RESEARCH THERE HAS BEEN MULTIPLE COMPLAINTS ABOUT THIS. SO FIRST THINGS FIRST REPLACED THE TCM WITH A NEW ONE AT THE DEALERSHIP. AFTER REPLACEMENT THE VEHICLE IS STILL NOT SHIFTING CORRECTLY.

TL* THE CONTACT OWNS A 2005 CHEVROLET COBALT. WHILE DRIVING 50 MPH, THE VEHICLE SLOWED DOWN, JERKED, AND ACCELERATED RAPIDLY ON ITS OWN. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE. THE FAILURE MILEAGE WAS 130,000.

2005 CHEVROLET COBALT. CONSUMER WRITES IN REGARDS TO VEHICLE ELECTRICAL ISSUES. *SMD THE CONSUMER STATED SHE EXPERIENCED PROBLEMS WITH THE CRUISE CONTROL AND CLUTCH NOT WORKING UPON PURCHASING THE VEHICLE. THE VEHICLE WAS TAKEN TO THE REPAIR SHOP 2-3 TIMES. IN JULY 2015, THE VEHICLE STALLED. *JB

TL* THE CONTACT OWNED A 2005 CHEVROLET COBALT. WHILE THE VEHICLE WAS PARKED AND THE ENGINE WAS TURNED OFF, A SECOND VEHICLE MADE CONTACT WITH THE REAR BUMPER. AS A RESULT, THE CONTACT'S VEHICLE ROLLED DOWN A HILL AND CRASHED INTO A TREE. THE VEHICLE WAS DESTROYED. THERE WERE NO INJURIES AND A POLICE REPORT WAS NOT FILED. THE CAUSE OF THE FAILURE WAS NOT DIAGNOSED. THE MANUFACTURER HAD NOT BEEN CONTACTED. THE CONTACT INDICATED THAT THE VEHICLE EXPERIENCED THE SAME FAILURE LISTED IN NHTSA CAMPAIGN NUMBER: 09V073000 (POWER TRAIN); HOWEVER, THE VIN WAS NOT INCLUDED IN THE RECALL. THE FAILURE MILEAGE WAS 133,000.

MY CAR HAS BEEN STALLING OUT AS IT GETS TO LOWER SPEEDS AND SHIFTING VERY HARD. THERE IS A CLICKING IN THE DASH SOMEWHERE AND THE SPEED ODOMETER WAS FLUCTUATING. IT HESITATES AND TRIES TO SHUT OFF AT EVERY STOP. LOOSING POWER AND SPEED EVEN DOWN HILL. THE POWER STEERING READING HAS BEEN COMING ON. AND THE DISPLAY FOR GAS MILEAGE WILL NOW GO TO ALL LINES NO NUMBERS. I AM STARTING TO BE AFRAID TO DRIVE MY CAR. THAT ITS GOING TO GET ME REAR ENDED WHEN I AM TURNING AND IT SHUTS OFF. I FEAR FOR MY SAFETY AND THE SAFETY OF MY CHILDREN. I WENT SO FAR AS TO THIS MORNING RECORDING THE DASH AS IT WAS ACTING UP SO I CAN SHOW MY HUSBAND. *TR

WHILE DRIVING HOME THE CHEVROLET COBALT (WHICH WE'VE ONLY HAD FOR TWO WEEKS) ENGINE SHUT OFF, LUCKILY WE WERE IN THE NEIGHBORHOOD GOING SLOW WHEN THIS HAPPENED. I STARTED THE CAR UP AGAIN AND PRESSED ON THE GAS BUT IT WOULD NOT GO FORWARD, NOW ONLY THE REVERSE WORKS. *TR

THE FIRST TIME IT HAPPENED, WAS AT INTERSTATE SPEEDS.(60 TO 70MPH) THE SECOND, WAS IN CITY STOP AND GO TRAFFIC. THE THIRD WAS BACKING OUT OF MY DRIVEWAY AFTER A 5 MINUTE IDLE. THE FOURTH WAS WHEN MY LAST MECHANIC WAS TEST DRIVING IT BECAUSE HE THOUGHT HE'D FIXED IT. DASH LIGHTS BLINK ON AND OFF, ALL WARNING LIGHTS COME ON, ENGINE COOLING FANS STOP OPERATING, TRANSMISSION HUNTS FOR WHAT GEAR IT SHOULD BE IN; RESULTING IN THE TRANSMISSION SELF DESTRUCTING. ENGINE MANAGEMENT, OTHER THAN THE COOLING FANS, SEEMS TO BE UNAFFECTED. I'VE REPLACED 4 TCM'S SO FAR; AS ALL MECHANICS SAY THAT IS THE PROBLEM. IT WORKS FOR A FEW DAYS OR A WEEK, THEN THE SAME PROBLEM MANIFEST. THIS SEEMS TO BE A PROBLEM WITH QUITE A FEW GM VEHICLES.

THE CAR WILL LOSE POWER, LIKE IT IS SHIFTING DOWN, TRANSMISSION SLIPPING, AND EITHER START TO STALL OR WILL STALL. SOMETIMES, IF IT HAS RUN FOR A LONG TIME THE PROBLEM TEMPORARILY GOES AWAY. NOT SAFE TO DRIVE HOWEVER AND 3 MECHANICS HAVE ATTEMPTED TO REPAIR WITH NO SUCCESS. *TR

TL- THE CONTACT OWNS A 2005 CHEVROLET COBALT. THE CONTACT STATED THAT WHEN HE TURNED THE VEHICLE ON AND THEN OFF IT FAILED TO RESTART. THE VEHICLE ALSO MADE A RUMBLING NOISE WHEN THE FAILURE OCCURRED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE IGNITION MODULE AND THE SPARK PLUG WIRES NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 93,000. RK

THIS HAPPENS TO ME ON DIFFERENT OCCASIONS I WHEN I PARK MY CAR OR STOP DRIVING I TRY TO SHUT MY CAR OFF AND I CANNOT MY KEY WILL BE STUCK IN THE IGNITION AND STILL RUNNING FOR ABOUT UP TO 30 MINS MY LAST TIME THIS PROBLEM HAPPENED TO ME. MY OTHER PROBLEM I AM HAVING IS I CAN START MY CAR PERFECTLY FINE BUT I TRY TO SHIFT THE GEAR FROM PARK TO DRIVE AND I CANNOT ITS LIKE ITS STUCK I PUT MY FOOT ON THE GAS AND TRY TO SHIFT IT BUT ALL I HEAR IS A CLICKING NOISE COMING FROM THE STEERING WHEEL AREA SOMETIMES I HAVE TO SIT WITH THE CAR RUNNING FOR ABOUT 15-20 MINS UNTIL I CAN FINALLY GET THE CAR IN DRIVE. *TR

I HAD THE IGNITION CYLINDER REPLACED ABOUT A YEAR AGO, DUE TO THE KEY NOT BEING ABLE TO RELEASE. THIS WAS A COMMON PROBLEM WITH 2005 MODEL YEAR COBALTS. WELL, THE VEHICLE IS DOING THIS AGAIN. THE KEY IS NOT BEING RELEASED FROM THE IGNITION CYLINDER. HOWEVER, THIS TIME I BELIEVE IT IS THE SHIFTER ASSEMBLY THAT HAS GONE BAD. THERE IS NO REVERSE LOCK OUT. I CAN FREELY CYCLE THROUGH THE GEARS WITHOUT APPLYING THE BRAKES WHICH IS A SAFETY HAZARD. I CAN PUT THE CAR IN REVERSE WITHOUT APPLYING THE BRAKES BY SIMPLY MOVING THE SHIFT LEVER. LITTLE TO NO FORCE IS NEEDED, I CAN ACCIDENTALLY KNOCK THE LEVER INTO REVERSE WITH THE LITTLEST OF FORCE. I HAVE YET TO CONTACT THE DEALER ABOUT THE ISSUE SINCE I AM SURE IT WILL COST A FORTUNE TO FIX EVEN THOUGH IT IS A DOCUMENTED PROBLEM WITH A FEW TECHNICAL SERVICE BULLETINS ON THE ISSUE. *TR

TL* THE CONTACT OWNS A 2005 CHEVROLET COBALT. THE CONTACT STATED THAT THE IGNITION SWITCH FAILED TO RELEASE THE KEY WHILE PARKED. THE VEHICLE WAS TAKEN TO A DEALER WHERE THE TECHNICIAN WAS UNABLE TO REMOVE THE KEY FROM THE IGNITION AND INFORMED THE CONTACT THAT HIS VEHICLE HAD A TRANSMISSION PROBLEM THAT WAS NOT COVERED UNDER THE RECALL. THE CONTACT STATED THAT THE VEHICLE WAS PREVIOUSLY REPAIRED UNDER NHTSA CAMPAIGN NUMBERS: 14V171000 (ELECTRICAL SYSTEM) AND 14V047000 (AIR BAGS, ELECTRICAL SYSTEM). THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 900.

WHILE DRIVING, THE CHECK ENGINE LIGHT CAME ON AND THE INFORMATION DISPLAY ON THE DASHBOARD FLASHED "POWER STEERING." THE CAR BEGAN SHIFTING IN AND OUT OF GEAR. THE SHIFTS ARE VERY ROUGH AND CAUSE THE CAR TO JERK. THERE IS ALSO A RAPID CLICKING SOUND THAT COMES FROM THE AREA OF THE GEAR SELECTOR. THE CODE FOR THE CHECK ENGINE LIGHT RELATES TO THE TRANSMISSION CONTROL MODULE. *TR

WHILE DRIVING ON A MAJOR HIGHWAY, "POWER STEERING" MESSAGE IS DISPLAYED ON DASH, WARNING CHIME SOUNDS REPEATEDLY, POWER DOOR LOCKS CYCLE AT RANDOM, INSTRUMENT PANEL GAUGES STOP WORKING INTERMITTENTLY AND JUMP AROUND, COMPLETE LOSS OF POWER, AND RANDOM WARNING LIGHTS APPEAR ON DASH. AT TIMES THE GAS PEDAL WAS COMPLETELY UNRESPONSIVE, THEN VEHICLE WOULD LURCH FORWARD - HAD A NEAR MISS INCIDENT WHEN THE LOSS OF POWER ON ACCELERATION FROM A RED LIGHT ALMOST CAUSED ANOTHER VEHICLE TO HIT US. ISSUE HAS OCCURRED AT RANDOM INTERVALS SINCE THE CAR WAS NEW, BUT HAS BECOME MORE FREQUENT LATELY AND TENDS TO OCCUR MORE OFTEN ON HOT DAYS. DEALER WAS UNABLE TO DUPLICATE CONCERN, DESPITE HUNDREDS OF SIMILAR COMPLAINTS ON THE INTERNET. *TR

MY CAR REPEATEDLY GO THROUGH TIMES OF FITS. THESE FITS INCLUDE LOSING POWER STEERING, POWER STEERING CHIME, TRACTION CONTROL CHIME, CLICKING BEHIND THE RADIO, SPINNING SPEEDOMETER, GAS GAUGE FAILS, JERKING OR HICCUPPING AS ONE PERSON DESCRIBED IT, OCCASIONAL STALLING. MY CAR WILL DRIVE FINE FOR WEEKS, LIKES ITS NEW EVEN, THEN ALL OF A SUDDEN IT HAS A FIT AND THIS GOES ON FOR DAYS. THIS STARTED WHEN MY CAR WAS A YEAR OR TWO OLD. I HAVE TAKEN IT TO THE DEALER A TOTAL OF 8 TIMES. EARLY ON WHEN THE CAR WAS YOUNGER IT WOULD SEEM TO BE REPAIRED ONLY DO START THIS PROBLEM AGAIN A YEAR LATER. NOW THAT THE CAR IS OLDER AND NOT UNDER WARRANTY I HAVE QUIT TAKING IT AS I DO NOT BELIEVE IT WILL HELP. THEY DO NOT SEEM TO KNOW HOW TO CORRECT THIS PROBLEM. THEY ARE RUDE TO ME. *TR
