NHTSA Complaint #10178872 — 2007 CHEVROLET IMPALA

I HAVE A 2007 CHEVY IMPALA WITH 7800 MILES ON IT. IN JANUARY, MY SERVICE TPMS WARNING LIGHT CAME ON IN MY DASH. IT WOULD GO OFF AFTER A FEW MINUTES. I ALSO NOTICED AT THE SAME TIME THAT MY REMOTE KEYLESS ENTRY AND REMOTE START DID NOT WORK MORE THAN 10 FEET AWAY FROM THE VEHICLE. I TOOK THE CAR TO A LOCAL DEALERSHIP (GRAFF CHEVROLET) AND THEY INFORMED ME OF AN ANTENNA THAT NEEDED TO BE REPLACED. I WAS TOLD THAT THE PART WAS UNAVAILABLE FOR AN UNDETERMINED AMOUNT OF TIME. THE DEALERSHIP WOULD NOT CHECK TO SEE IF THE TMPS SENSOR IN THE LEFT REAR TIRE WAS DEFECTIVE LIKE I ASKED THEM TO. THEY SAID THE NEW UNRELEASED PART SHOULD SOLVE THE PROBLEM, BUT THEY DON'T KNOW FOR SURE. THE LEFT REAR SENSOR WOULD ALWAYS TRIGGER THE WARNING LIGHT, BUT THE TIRE IS PROPERLY INFLATED. NOT BEING ABLE TO FIX THE PROBLEM IS MAKING ME THINK THAT I HAVE A FLAT TIRE ON MY CAR EVERY TIME THE LIGHT GOES ON. *NM
