NHTSA Complaint #11166766 — 2018 MAZDA CX-5

JUNE 4 2018 MY BRAND NEW 2018 MAZDA CX 5 THAT I BOUGHT FROM MARIN MAZDA IN SAN RAFAEL CA DRIVING ON FREEWAY AT APPROXIMATELY 68 MPH MY CAR SUDDENLY IS SLOWING DOWN- LIKE SELF BRAKING ON ITS OWN- I WAS NOT BRAKING- THIS WAS HAPPING WHILE I WAS ACCELERATING -IT FELT LIKE I WAS TOWING A LARGE TRACTOR - THIS RESISTANCE KEEPS RECURRING CAUSING SAFETY CONCERN AS WELL AS BAD GAS MILEAGE- WHILE THIS ISSUE IS HAPPENING I GET BETWEEN 15 -17 MILES PER GAL. - TOOK PICTURES OF FUEL MONITORING SYSTEM. HAVING TO MAKE MY WAY TO THE NEAREST EXIT WITH CARS HONKING AT ME WAS DANGEROUS. CAR HAD 350 MILES ON IT. TOOK CAR BACK TO MARIN MAZDA A COUPLE DAYS LATER FOR THIS ISSUE AND BECAUSE IT IS VERY LOUD WITH EXCESSIVE ENGINE NOISE WHEN STARTED EVERYDAY. VERY CONCERNING AS TO IT BEING A NEW CAR. DEALER SAID THAT'S JUST HOW MAZDA'S SOUND IT'S OK WE DIDN'T NOTICE ANYTHING OUT OF THE ORDINARY. YOUR CAR IS FINE. THE WHEEL RESISTANCE YOU ARE FEELING IS PROBABLY BECAUSE THEY SPRAY STUFF ON THE CAR TO PREVENT RUST BEFORE THEY SHIP VEHICLE, THAT COATING JUST NEEDS TO BURN OFF. SO YOU NEED TO DRIVE IT TO BURN IT OFF. YOUR CAR IS OPERATING THE WAY IT WAS INTENDED TO. REALLY - THIS IS NOT HOW ANY NEW CAR SOUNDS OR DRIVES. I HAVE A PASSENGER WITH ME AT THIS TIME HE ALSO STATED THIS WAS NOT A NORMAL CONDITION FOR ANY VEHICLE THAT IS OPERATING PROPERLY.
