TRANSMISSON WILL SHIFT HARD SOMETIMES FROM COMPLETE STOP OR WHILE TRAVELING , MAINLY FROM COMPLETE STOP OR STOPPING AT STOP LIGHT AND NOT A COMPLETE STOP . ITS LIKE IT IS SLIPPING. NOW AIR BAG LIGHT IS COMING SOMETIMES WHEN CAR IS 1ST CRANK. DASH IS ALSO COMING APART. CAR HAS 118,000 MILES ON IT. TRASMISSION IS WORRING ME THE MOST.
TL* THE CONTACT OWNS A 2006 CHEVROLET MONTE CARLO. WHILE DRIVING AT AN UNKNOWN SPEED, THE VEHICLE STALLED WITHOUT WARNING. WHEN ATTEMPTING TO START THE VEHICLE AND DEPRESSING THE BRAKE PEDAL, THE ENGINE FAILED TO OPERATE WITHOUT WARNING AND THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE FAILURE RECURRED SEVERAL TIMES. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 105,000.
BOUGHT CAR AT 29K IN JUNE 2007. AROUND 36K THE TRANSMISSION SENSOR BETWEEN THE GAS LINE AND THE TRANSMISSION DECIDED TO OVERRIDE MY BREAKING. NEARLY KILLED ME BECAUSE THE CAR WOULD NOT STOP. (HAD TO PUT IN NEUTRAL TO MAINTAIN CONTROL). HAD TO FIGHT WITH CHEVY TO GET WARRANTY FIX FOR SEVERAL WEEKS. AROUND 41K THE CAR DECIDED THAT THE TEMP OUTSIDE WAS -38 OR -40 DEGREES AND WOULD INSIST ON RUNNING HEAT DURING SUMMER. WAS TOLD COMPUTER WAS BAD AND WOULD HAVE TO SPEND $$$$ TO FIX (AND ASKED WHY I WOULD BUY A CAR WITH A BAD COMPUTER!). AROUND 145K OIL PRESSURE SENSOR WENT OUT--IN LESS THN15 K, AM NOW HAVING TO REPLACE 4TH ONE. THERE ARE SEVERAL OTHER WEIRD ISSUES WITH THIS VEHICLE THAT ARE WELL DOCUMENTED WITH MY MECHANIC. AND NOW FINALLY GET RECALL NOTICE AND TOLD THE BEST FIX IS TO HAVE KEY BY ITSELF WITH NOTHING ELSE--FOB AWAY FROM KEY. I SUSPECT THIS CAR IS A LEMON THAT HAS COST ME THOUSANDS OF DOLLARS IN REPAIRS. *TR

I PURCHASED A 2006 MONTE CARLO LAST YEAR WHICH HAD 25,000 MILES ON IT RIGHT WHEN IT HIT 30,000 MILES THE HEAT STOPPED WORKING AT IDLE. IT ONLY WORKS WHEN ACCELERATING. IN THE WINTER EVERY STOP LIGHT YOU GO TO OR ANY TIME YOU ARE COASTING THE WINDSHIELD AND OTHER GLASS WILL FOG AND FREEZE UP I HAVE HAD MANY NEAR ACCIDENTS BECAUSE OF THIS INCLUDING VEERING INTO ONCOMING TRAFFIC. I HAVE TWO YOUNG CHILDREN AND I DON'T NEED THEM GETTING HURT OR WORSE BECAUSE CHEVY CANT STAND BEHIND THERE CARS. ALMOST EVERYONE I HAVE TALKED TO WITH THIS CAR AND ONLINE HAVE THE SAME PROBLEM SOMETHING NEEDS TO BE DONE. *TR
I NOTICED A SMELL OF MOLD FROM THE AC VENTS, I TOOK THE CAR TO CITY CHEVROLET IN CHARLOTTE, NC. THEY REPLACED THE AC CONDENSER UNIT. THIS TOOK CARE OF THE SMELL FOR THE SUMMER MONTHS. THE SMELL HAS NOW RETURNED AND IS GETTING WORSE BY THE DAY. THE SERVICE AGENT SAID THAT GM WAS AWARE FOR THE PROBLEM BUT WAS DOING NOTHING TO CORRECT. I WAS ALSO TOLD THIS IS A DESIGN FLAW DUE TO THE VENTS IN THE CONDENSER BEING TOO SMALL NOT ALLOWING THE BUILT UP WATER TO EVAPORATE. THIS ISSUE IS STARTING TO CAUSE HEALTH PROBLEMS SUCH AS BRONCHITIS AND SINUS INFECTIONS. *TR
INTERNAL RADIATOR CRACK. THIS ALLOWED THE COOLANT AND TRANS FLUID TO COMMINGLE THUS CAUSING THE TRANSMISSION TO SLIP. IT ALSO HAD POTENTIAL TO DAMAGE MANY INTERNAL COMPONENTS. NO EXTERNAL DAMAGE THUS MUST BE MANUFACTURE DEFECT. *TR
I HAVE INFREQUENT LIFTER NOISE. I HAVE BEEN TOLD THAT THIS IS PISTON SLAP. IT'S NOT PISTON SLAP. THIS PROBLEM HAS BEEN REPORTED TWICE. I GOT THE SAME RESPONSE. PISTON NOISE. SYMPTOMS: COLD START..WINTER-FALL OR SUMMER...LIFTER NOISE..VALVES CLATTER...ENGINE RUNS ROUGH..NO CODES..AFTER IDLING FOR A FEW MINUTES THE VALVES PUMP UP AND THE ROUGHNESS AND NOISE GO'S AWAY... I ALSO HAVE THE ODOR OF BURT TRANSMISSION FLUID (HAIR BURNING) WHEN ACCELERATING.. I ALSO OIL 1QT A MONTH. *NM
