What 258 owners told NHTSA about the 2012 Chevrolet Impala Eco Eassist

WHILE DRIVING MY CAR HIGHWAY SPEED WAS 65MPH, AT THAT RATE OF SPEED MY VEHICLE WAS PICKING UP SPEED AND WHEN I WENT TO PRESS ON MY BRAKES, IT WAS IF I WAS DRIVING ON ICE AND MY CAR WAS SKIDDING. TWO DAYS LATER I STOPPED FOR GAS AND MY CAR WOULDN'T START, AFTER MY 3RD ATTEMPT, IT STUTTERED HARD TIME TURNING OVER. ONCE IT DID I TURNED IT OFF BUT THE CAR WAS STILL RUNNING. I DID THIS SEVERAL TIMES. VERY SCARED TO DRIVE MY CAR BACK HOME BECAUSE I'M OUT OF TOWN. MY LIGHTS SAYS I HAVE LOW RIGHT TIRE PRESSURE BUT I DON'T, IT'S BACK LEFT TIRE FOR SOME ODD REASON. *TR

I WAS DRIVING AND AFTER MAKING A LEFT TURN, MY SERVICE TRACTION CONTROL, SERVICE BRAKE ASSIST, AND ABS LIGHT ALL POPPED ON. IT WENT ON AND OFF FOR MANY DAYS AS I WOULD STOP AND THEN RE-START THE CAR. I FINALLY TOOK IT TO A CHEVY DEALERSHIP AND WAS TOLD THEY TESTED THE FRONT ABS CONNECTOR AND ADJUSTED THE TIMING. LIGHTS AND CODES WENT OFF FOR ABOUT TWO WEEKS THEN POPPED BACK ON UPON MAKING A LEFT TURN. IN ADDITION TO THE LIGHTS AND CODES, THE CAR NOW MAKE A LOUD GRINDING NOISE AND THE CAR STALLS. I HAVE BEEN AT A LIGHT IN THE MIDDLE OF MAKING A TURN WHEN THE CAR WILL STALL AND NOT LET ME TAKE OFF- THE TRACTION CONTROL SYMBOL WILL COME ON AND I WILL BE STUCK TRYING TO ACCELERATE. THIS IS VERY DANGEROUS AS I HAVE ALMOST BEEN HIT FROM BEHIND A FEW TIMES DUE TO NOT BEING ABLE TO ACCELERATE IN A TIMELY FASHION. I HAVE GONE ON CHEVY IMPALA FORUMS LOOKING FOR OTHER DRIVERS WHO MAY HAVE EXPERIENCED THIS ARE THERE ARE A GOOD NUMBER OF THEM. IT SEEMS TO BE AN ELECTRICAL PROBLEM. *JS

IN FEB. 2014 STARTED GETTING INTERMITTENT COMPUTER MESSAGES CONCERNING, SERVICE TRACTION CONTROL, SERVICE STABILATOR(?) CONTROL, REDUCED ENGINE POWER. MESSAGE OCCURS RANDOMLY, AND STAYS FOR A DAY OR LESS, THEN GOES TO JUST SHOWING THE ENGINE ICON, THEN CLEARS SELF. CAR WAS PURCHASED USED (16000 MILES) FROM DEALER. ERROR CODES P2138 AND P2122 WERE SHOWING PER DEALER. CAR WAS OWNED IN RENTAL FLEET IN EAST ELMHURST, NY (QUEENS, SEVERELY AFFECTED) DURING HURRICANE SANDY, BUT SHOWED NO SERVICE AS BEING DONE, AFTERWARDS. NEXT ENTRY SHOWED CAR IN UPSTATE NY, ON DEALERS LOT. HAVE BEEN TOLD (3/25/2014) THAT PART WAS ORDERED AND WOULD BE IN IN A COUPLE DAYS. 17 DAYS LATER, TOLD ":PART NOT IN--WILL CALL WHEN HERE" AND REPLACE AT NO CHARGE. STILL WAITING FOR CALL FROM DEALER. *JS

IM GOING DOWN THE ROAD MASH ON THE GAS DOING 38 AND THE VEHICLE IS OUT OF CONTROL. I LITERALLY HAD NO CONTROL OVER THE CAR. IM DOING 45 TO 50 AND THE VEHICLE IS DRIVING ME RIGHT INTO THE SHOULDER OR INTO OTHER TRAFFIC I HAD TO LAY OFF THE GAS TO GAIN CONTROL OF CAR DOING SUCH LOW SPEED. I WAS DRIVING ON THE HIGHWAY AT THE TIME. AND WAS BLOWN AWAY.HOW THE SUSPENSION AND CONTROL OF THE CAR WAS NOT IN MY HAND NO MORE. THIS IS A SAFETY DEFECT THAT EVERYBODY IS TALKING ABOUT ON ONLINE. GM NEEDS TO FIX THIS ITS THEIR COMPUTER SYSTEM IN THE CAR THAT MESSING UP THE WHOLE CAR.AND IF THERE IS POLICE FLEET OF THESE IMPALAS AND THEY USING THESE IN POLICE CHASES. THE CHASES COULD TURN UGLY. I DROVE AND BUNCH OF POLICE FLEET VEHICLES AND NEVER HAD ONE WHERE I DIDN'T HAVE CONTROL OF IT GETTING INTO HIGH SPEEDS. THE MAIN CAUSE OF THESE IS THAT IMPALA HAS FWD WITH 308 HP ALL UP FRONT WHAT WAS THEY THINKING. IT'LL BE GOOD FRO A DRAG CAR GOING IN A STRAIGHT LINE. START FROM A STAND STILL AND TRY TO GET UP SPEED FAST. DOING IT WITHOUT CRASHING OR MERGING INTO ANOTHER LANE IS IMPOSSIBLE. GET IN A 2012 CHEVY IMPALA LT WITH 308 HP THEN YOU WILL SEE THE PROBLEM. ALSO EXISTS ON SS MODELS AS WELL. *TR
