2009 Chevrolet Impala

CAR CONTINUOUSLY GETS A REDUCED POWER MESSAGE AND GOES DOWN TO 25 MPH. IN MID JANUARY DID THE SAME THING, BUT STALLED ON I90 OHIO TURNPIKE. ALMOST HIT BY A SEMI TRUCK. HAVE HAD THE CAR IN THE SHOP NO LESS THAN 5 TIMES FOR THE SAME PROBLEM. AT GM AND NON GM REPAIR SHOPS. WE HAVE HAD THIS SAME REDUCED POWER ON CITY ROADS, AND THE HIGHWAY, IT SEEMS ALWAYS WHEN IT IS WET, RAINY OR SLUSHY. IT REALLY APPEARS TO BE A WATER CAUSES THE PROBLEM. WE HAVE PAID FOR TWO SETS OF THROTTLE BODY, SPEED CONTROL SENSOR AND HARNESSES. THE PROBLEM CONTINUES TO PERSIST AND APPEARS TO BE DANGEROUS.

WHILE DRIVING, THE CAR IN MOTION IT COMPLETELY LOSES POWER. HAVE EXPERIENCED THIS WHILE ON HIGHWAY, INTERSTATE, AND IN TOWN ROADS. SO PROBLEM OCCURS AT ANY SPEED, AND RESULTS IN VEHICLE COASTING TO A STOP AS THE STEERING AND BRAKES STOP WORKING TOO. HAS HAPPENED TO ME HUNDREDS OF TIMES AS WE CAN NOT PIN POINT PROBLEM, AND HAS REPLACED NUMEROUS DIFFERENT PARTS TRYING TO SOLVE IT. WHEN POWER LOSS OCCURS THERE IS VERY LITTLE TO NO TIME AT ALL FOR DRIVER TO COAST & STEER VEHICLE & OCCUPANTS TO SAFETY AREA ON SIDE OF ROAD. THE DASHBOARD INFORMATION CENTER WILL STATE "STARTING DISABLED, SERVICE THROTTLE" ALSO ENGINE POWER REDUCED" AND "SERVICE STABLITRAK." A NEW THROTTLE HAS BEEN PUT IN VEHICLE AND STILL DOES SAME THING. OVER THE YEAR IVE BEEN DEALING WITH THIS ISSUE IVE NOTICED IT DOES IT MORE IN WARM WEATHER. AFTER VEHICLE COAST TO A STOP AND IS PUT IN PARK AND TURNED OFF, WAIT 5 TO 10 MINUTES THEN VEHICLE WILL START UP AND NO INFORMATION OR LIGHTS DISPLAY IN DASH CENTER, LIKE IT NEVER HAPPENED.

DROVE MY VEHICLE TO ATTEND CHURCH ON A SUNDAY MORNING. AFTER CHURCH, RETURN TO MY VEHICLE TO GO HOME. I STARTED MY VEHICLE AND PUT IT IN DRIVE GEAR. THE VEHICLE WOULDN'T MOVE. I SHIFTED IT TO 2ND GEAR AND IT MOVED SLOWLY AND I WAS ABLE TO DRIVE HOME. I GOT NO PRIOR WARNING OF ANY PROBLEM BEFORE PARKING. NO CHECK ENGINE LIGHT AND IT SCARED ME BECAUSE IT COULD HAVE OCCURRED WHILE I WAS ON THE BUSY INTERSTATE. I HAVE NOT HAD IT REPAIRED BECAUSE THE PROBLEM CAN'T BE ISOLATED BY THE TRANSMISSION REPAIR SHOPS BECAUSE THERE IS NO CHECK ENGINE LIGHT ON. THE TRANSMISSION SHIFTED FINE PRIOR TO THIS. THE VEHICLE ONLY HAS 117,000 MILES.

I PLACED MY CAR IN PARK, WHILE THE CAR WAS STILL RUNNING. WHEN I GOT BACK IN, AND TRIED TO PUT IT INTO GEAR, THE CONSOLE SHIFTER SEEMED LIKE IT WAS LOCKED IN PLACE, AND WOULDN'T LET ME PUT THE CAR IN GEAR. THERE IS APPARENTLY A SWITCH UNDER THE CONSOLE COVER THAT ALLOWS ME TO TEMPORARILY FIX THIS ISSUE, BUT I HAVE TO DO SO EVERY TIME I WANT TO PUT MY CAR INTO GEAR FROM PARK. ONLY HAPPENS WHEN MY CAR IS IN PARK. I DON'T KNOW IF THIS IS A RECALL ISSUE OR NOT. BUT ANY REPLY ON THIS ISSUE, AS WELL AS WHAT I NEED TO DO TO GET IT FIXED WOULD BE MUCH APPRECIATED. THANK YOU FOR YOUR TIME.

LATELY, I HAVE BEEN HAVING ISSUES WITH THE ACCELERATION OF MY VEHICLE. EVERY SO OFTEN, MY ENGINE LIGHT COMES ON AND I GET A "ENGINE REDUCED" NOTIFICATION, AND MY VEHICLE SLOWS DOWN. WHENEVER I REACH 40MPH, MY HP METER DROPS AND MY CAR STARTS SHAKING. THERE HAS EVEN BEEN A TIME WHEN MY CAR WOULD COMPLETELY SHUT OFF AND DISPLAY "IGNITION DISABLED". EACH TIME THIS HAS HAPPENED, THE VEHICLE WAS MOVING ON A HIGHWAY. I WENT TO A SHOP TO GET THE ERROR CODES AND I WILL UPLOAD THEM.
