NHTSA Complaint #10786240 — 2012 DODGE RAM 1500

RECEIVED RECALL NOTICE THAT A STEERING WHEEL HARNESS COULD RUB AND DEPLOY THE AIRBAG AT ANY TIME. I TOOK THE TRUCK TO HOLLYWOOD CHRYSLER HOLLYWOOD FL AND THEY REPAIRED AND RETURNED. WHEN I ARRIVED AND FOR THE PRECEDING MONTHS PRIOR MY "FUEL ECONOMY DISPLAY" INDICATED MY AVERAGE MILEAGE WAS 15.8 GALLONS PER MILE REASONABLY WITHIN THE SPECS FOR THIS VEHICLE. FOLLOWING THE WIRING HARNESS REPAIR THE DISPLAY NOW (AND FOR MORE THAN 2 WEEKS ) REPORTS 11.8 MPG. SOMEHOW THE REPAIR ALTERED THE FUEL USAGE OF THE VEHICLE. THE DEALER CHECKED AND SAID NOTHING WAS WRONG. BUT MY MILEAGE HAS GONE FROM 15.8 TO 11.8. I'M NOT DRIVING DIFFERENTLY. I'M LOSING 30% OF MY GAS AND THE VEHICLE IS NOW UNDER ADVERTISED SPECS OF 14/20 MPG THERE IS AN ISSUE THEY DON'T WANT TO DISCUSS. CAN THE NHTSA CONTACT OTHER OWNERS WITH THIS REPAIR AND VERIFY? CAN YOU HELP? THANKS
