2011 Chevrolet Impala

WHEN MY IMPALA WAS 4 YEARS OLD AND 42000 MILES(APRIL OR MAY OF 2013), BOTH REAR DOOR LOCKS REFUSED TO LOCK OR UNLOCK. I CONTACTED MY DEALER AND HE STATED THAT IT WAS OUT OF WARRANTY. I THEN CONTACTED GMS CUSTOMER SERVICE WHICH REITERATED THE SAME THING. AFTER INVESTIGATING ONLINE, THERE ARE QUITE A FEW BLOGS WITH CUSTOMERS WHO HAVE THE SAME PROBLEM. TO REPLACE THESE LOCKS COSTS APPROXIMATELY $800. I CONTACTED YOUR ORGANIZATION THIS MORNING AND THEY TOLD ME TO CONTACT CHEVROLET AT 1-800-222-1020. WHEN I CONTACTED THEM, I WAS INFORMED THAT THE SERIAL NUMBER DID NOT FALL UNDER ANY RECALLS. HOWEVER, CHEVROLET DOES HAVE A DOOR LOCK RECALL. *TR

I OWN A 2011 CHEVY IMPALA AND FOR THE PAST COUPLE MONTHS ON 6 DIFFERENT OCCASIONS AS I AM DRIVING DOWN THE FREEWAY MY ENGINE POWER IS REDUCED AND "SERVICE STABILITRAK" LIGHT APPEARS. AS I HAVE RESEARCHED AND HAVE FOUND THAT THIS IS A COMMON AND VERY UNSAFE PROBLEM AMONG GM VEHICLES. I HAVE ALSO FOUND THAT THERE IS NO CLEAR SOLUTION TO WHY THIS IS HAPPENING WITH MANY MECHANICS STUMPED AND REPLACING PARTS IN WHICH THE PROBLEM RECURS ONLY A SHORT TIME LATER. I HAVE ALSO FOUND REPLACING WHAT THE DIAGNOSIS OF CODE P2135 SAYS THE PROBLEM STILL MAY NOT BE SOLVED. AS ONE CAN IMAGINE THAT DRIVING DOWN THE FREEWAY WITH A SEMI,HEAVY TRAFFIC,ETC. AND LOSING ENGINE POWER MAY LEAD TO SIGNIFICANT NEGATIVE RESULTS. I HAVE NOT INSTALLED ANY PARTS OTHER THAN TIRES AFTER PURCHASING OF VEHICLE. *TR
