2008 Chevrolet Impala Electronic Stability Control Esc Engine Problems

RANDOMLY I RECEIVE THE MESSAGE "SERVICE TRACTION CONTROL - ENGINE POWER REDUCED" - THERE IS NO RHYME OR REASON. IT HAPPENS ON NICE DAYS, RAINY DAYS, WHETHER OR NOT I AM GOING UPHILL, DOWNHILL OR ON FLAT SURFACES. ON AT LEAST ONE OCCASION WHILE DRIVING ON THE HIGHWAY, THE ENGINE SHUT OFF AND I HAD TO COAST FROM LANE 2 TO THE SHOULDER. AFTER 20 MINUTES, IT RESTARTED. *TR

ENGIME POWER REDUCED SEEVICE TRACTUON CONTROL. WHILE DRIVING POWER IS CUT TO NEAR NOTHING. ABOUT 20 MPH. AFTER SHUTTING THE CAR OFF AND STARTING A FEW HOURS LATER IT'S FINE. A COUPLE DAYS LATER IT HAPPENS AGAIN. FAULTY EQUIPMENT FROM GM.

2006-2009 CHEVROLET IMPALA SS TICKING NOISE, ENGINE MISFIRE AND/OR SES LIGHT. THIS MAY BE THE RESULT OF AN AFM (ACTIVE FUEL MANAGEMENT FOR DISPLACEMENT-ON-DEMAND) LIFTER THAT UNLOCKS AS SOON AS THE ENGINE IS STARTED OR ONE THAT IS MECHANICALLY COLLAPSED/STUCK. IF AN AFM LIFTER UNLOCKS AS SOON AS THE ENGINE IS STARTED, A SES LIGHT AND DTC P0300 WILL BE EXPERIENCED WITH ENGINE MISFIRES ON CYLINDER 1, 4, 6 OR 7 BUT IT IS UNLIKELY THAT ANY NOISE WILL BE EXPERIENCED. IF AN AFM LIFTER IS MECHANICALLY COLLAPSED/STUCK, A CONSISTENT VALVETRAIN TICK NOISE, SES LIGHT AND DTC P0300 WILL BE EXPERIENCED WITH ENGINE MISFIRES ON CYLINDER 1, 4, 6 OR 7.

WHILE I WAS DRIVING MY CAR, ABOUT TO ACCELERATE, ALL OF A SUDDEN, A "SERVICE TRACTION CONTROL" MESSAGE CAME ON AND SECONDS AFTER THAT, THERE WAS A "ENGINE POWER IS REDUCED" MESSAGE. AT THIS POINT THERE WAS SOME HESITATION IN THE VEHICLE. I PULLED OVER AND SHUT THE CAR OFF. WHEN I TURNED THE CAR ON, AFTER 2 MINUTES, I RECEIVED THE SAME MESSAGE. I TOOK THE VEHICLE TO MY MECHANIC, AND HE COULDN'T FIND ANYTHING WRONG WITH IT. I CALLED MY LOCALE GM DEALER AND FOR A "NOMINAL" CHARGE, THEY WOULD TAKE A LOOK AT IT. SINCE THEN, I HAVE RESEARCHED IT ON LINE, AND HAVE FOUND THAT THERE HAVE BEEN NUMEROUS COMPLAINTS ABOUT THE SAME ISSUE. IT IS A SHAME THAT GM HAS DONE NOTHING TO FIX THIS. I'M GLAD I WAS NOT ON THE HIGHWAY WHEN THIS HAPPENED, AS THE LOSS OF SPEED AND LACK OF ACCELERATION COULD HAVE CAUSED AN ACCIDENT.

OUT OF NO WHERE WHILE DRIVING THE DISPLAY SAYS "ENGINE POWER REDUCED" AND THEN SWITCHES TO "SERVICE TRACTION CONTROL". I HAVE LIMITED POWER, THE CHECK ENGINE LIGHT COMES ON AND SO DOES THE TRACTION CONTROL LIGHT. I CAN DRIVE THE CAR TO WHERE I AM GOING, BUT NO ACCELERATION. *JS
