ON COLD START (7AM, BETWEEN 60 AND 70F DEGREES), THERE'S A STRONG GAS SMELL ON BOTH THE CABIN AND OUTSIDE THE VEHICLE. NO CHECK ENGINE LIGHT IS ON OR ANY OTHER INDICATOR OF A FAILURE. THERE'S NO VISIBLE LEAKS ON THE UNDERHOOD OR MY DRIVEWAY. REALLY SCARED TO TAKE MY KIDS TO SCHOOL UNLESS MB SOLVE THIS PROBLEM. VEHICLE STILL UNDER WARRANTY, MB DEALERSHIP SHOULDN'T CHARGE FOR THE INSPECTION. TAKING VEHICLE TO EL PASO TX DEALERSHIP. WILL SEE WHAT HAPPENS.

MESSAGE: DATE: 06/07/2016: RECENTLY, I PURCHASED A 2016 MERCEDES GLC300 AND WAS VERY UNHAPPY WITH THE FACT THAT THE ECO MODE IS THE DEFAULT AND IT HAS TO BE TURNED OFF MANUALLY EACH TIME YOU START THE ENGINE.

WHEN THE CAR IS STOPPED THE ENGINE TURNS OFF AND WILL START IF ONE PRESSES THE GAS PEDAL. FOR EXAMPLE; WHEN TURNING LEFT AT AN INTERSECTION IT IS VERY UNC…
