I WAS DRIVING ON ICY AND SNOWY ROADS AND MY ENGINE POWER REDUCED WARNING LIGHT CAME ON. I DROVE SEVERAL MILES TO MY DESTINATION. MY CAR SAT FOR 6 HOURS. I GOT IN TO LEAVE AND THE ENGINE LIGHT WAS ON BUT NOT THE WARNING. AFTER DRIVING ABOUT TEN MILES MY ENGINE POWER REDUCED LIGHT CAME ON AGAIN. THIS HAPPENED MULTIPLE TIMES FOUR YEARS AGO AND IT'S VERY FRUSTRATING TO HAVE IT HAPPENING AGAIN. IT SEEMS TO OCCUR MORE FREQUENTLY WHEN THE ROADWAY IS WET. AFTER READING ONLINE, IT SEEMS THIS IS HAPPENING TO MANY OTHER CHEVROLET CARS ALSO.

STARTED THE CAR AND IMMEDIATELY UPON PULLING OUT OF PARKING LOT THE SERVICE TRACTION CONTROL ERROR MESSAGE AND REDUCED ENGINE POWER MESSAGES APPEARED. THIS IS THE 3RD TIME THIS HAS HAPPENED ON THIS CAR. HAVE ENTERED PROBLEM REPORTS FOR THE 1ST 2 OCCURRENCES ON THIS SITE. REPLACED ACCELERATOR PEDAL POSITION PEDAL SENSOR. NONE OF THESE 3 OCCURRENCES WERE COVERED UNDER WARRANTY. IT WAS 14 MONTHS SINCE THE LAST OCCURRENCE AND WARRANTY WAS FOR 12 MONTHS.

I WAS DRIVING IN TRAFFIC AROUND 5:30PM CST ON US 59 N AND RANKIN RD TUESDAY 11/15/16 WHEN MY VEHICLE LOST ENGINE POWER. I WAS UNABLE TO ACCELERATE OR STEER AND THE ONLY LIGHT THAT CAME ON IN THE CAR WAS THE SERVICE TIRE MONITOR SYSTEM. I MANAGED, SOMEHOW, TO STEER THE VEHICLE TO THE LEFT SHOULDER OF THE FREEWAY AND PUT IT IN PARK. I TURNED OFF THE VEHICLE AND WHEN I WENT START IT AGAIN, AFTER RELEASING THE KEY, IT MADE A STUTTERING TO START SOUND OVER AND OVER AGAIN EVEN THOUGH I WAS NO LONGER TOUCHING THE KEY. WHEN I TRIED TO START IT AGAIN IT TURN ON AND THEN BACK OFF AND CONTINUED TO DO THIS AT LEAST 3 MORE TIMES. I EVENTUALLY HAD IT TOWED TO MY HOME AND AFTER READING ONLINE TODAY AT FORUMS.EDMONDS.COM MANY PEOPLE HAVE BEEN HAVING THIS ISSUE WITH IMPALA'S AND SUBURBAN'S FROM GM FOR AT LEAST 4 YEARS NOW, FIRST POST IS BACK IN 2012. GM NEEDS TO PUT A RECALL ON THESE VEHICLES AND FIX THE ISSUE BEFORE IT MORE FATALITIES, AS PROVEN IN THEIR EARLIER 2014-2015 RECALL. THEY JUST DID A RECALL ABOUT A YEAR AGO FOR IMPALA'S HAVING AN ISSUE WHERE THE IGNITION SWITCH WOULD THEN SWITCH INTO THE OFF POSITION WHILE DRIVING IF YOU HIT A BUMP TOO HARD AND HAD TOO MUCH WEIGHT ON YOUR KEYS. I GOT MY VEHICLE SERVICED FOR THAT RECALL ISSUE BUT IT SEEMS LIKE THEIR FIX FOR THAT WAS INCORRECT AND NOT THE ISSUE SEEING AS MY VEHICLE, AND SEVERAL OTHERS, STILL SHUTS DOWN WHILE DRIVING AND THE IGNITION IS STILL IN THE ON (NOT OFF) POSITION, YOU LOSE ACCELERATION AND STEERING. THIS IS EXTREMELY DANGEROUS AND WILL CAUSE MORE DEATHS, INJURIES, AND ACCIDENTS. PLEASE GET THIS TO GM AND HAVE THEM CORRECT THIS ISSUE IN ALL THEIR MODELS WITH SENSOR THROTTLE BODY'S INSTEAD OF WIRED ONES. THEY ALSO NEED TO FIX THE ISSUE OF DOOR AND A/C ACCUATORS IN THEIR MODELS, AS ITS BEEN DESCRIBED TO ME AS A COMMON ISSUE IN GM MODELS. THIS IS A VERY UNSAFE ISSUE FOR ALL DRIVERS GM OR NOT. MORE ACCIDENTS WILL FOLLOW.
