NHTSA Complaint #10668145 — 2013 HONDA PILOT

PURCHASED VEHICLE USED AS A HONDA CERTIFIED VEHICLE ON 10/23/14. DURING TEST DRIVE WE DID NOT NOTICE VIBRATION IN DRIVE TRAIN - POSSIBLY BECAUSE FLUIDS WERE COLD. DURING A ROAD TRIP 2 WEEKS AFTER ABOVE DATE, WE NOTICED A VIBRATION IN 51, 52, 53 MPH RANGE. FELT LIKE TRANSMISSION OR TORQUE CONVERTER WAS TRYING TO SHIFT UP OR DOWN. TOOK BACK TO DEALERSHIP AND EXPLAINED PROBLEM, SERVICE WRITER TOOK FOR A TEST DRIVE AND EXPLAINED THAT HE FELT IT WAS WHEN ENGINE WAS GOING INTO "ECONOMY" MODE AND HALF THE CYLINDERS WERE SHUTTING DOWN.???? ON A LATER ROAD TRIP ON MORE OPEN HIGHWAY, WE NOTICED SAME VIBRATIONS IN 61, 62, 63 MPH RANGE - I WATCHED THE ECON. DASH LIGHT AND IT DIDN'T NECESSARILY CHANGE WHEN WE FELT VIBRATIONS. TOOK BACK TO DEALERSHIP AND I DROVE VEHICLE WHILE SERVICE WRITER WATCHED, LOOKED, AND LISTENED. HE SAID HE COULD FEEL VIBRATION BUT UNTIL A WARNING LIGHT CAME ON, THEY MIGHT SPEND MANY HOURS/DAYS TRYING TO FIND PROBLEM BUT NOT LOCATE IT. WE ARE KEEPING OUR FINGERS CROSSED THAT NOTHING SERIOUS DEVELOPS AND ENDANGERS LIVES OR VEHICLE! *TR
