The contact owns a 2017 Mazda Mazda6. The contact stated while driving at slower speeds and depressing the accelerator pedal, there was a delay before the vehicle responded. Additionally, the contact stated that after refueling the vehicle, the contact became aware of a fuel leak on the driveway. The vehicle was taken to an independent mechanic to be diagnosed and the contact was informed that the fuel tank was rusted and the fuel sending unit needed to be replaced.

I have a 2017 Mazda 6 that has an extremely loud engine. I have taken it in and I’m told the car is fine but I can feel the engine knocking through the pedal as I drive. The sound has gotten louder over time and it’s not getting any better. I’ve had some belts change and keep up my regular maintenance and Mazda can’t seem to figure out what the issue is. I have friends with the same model and their engine sounds normal.

I BOUGHT MY 2017 MAZDA 6 BRAND NEW. WHILE THE CAR WAS IN WARRANTY IN JANUARY 2020 WHILE I WAS DRIVING WITH 50 MILES IN HOUR, THE ENGINE WAS RUNNING ROUGH, THE ENGINE LIGHT WAS ON AND THE ENGINE STALL. THE CAR WAS TOWED BY MAZDA AT DEALER. THEY REPLACED THE FUEL PUMP AT THAT TIME. FEW DAYS AGO WHILE I WAS DRIVING WITH 35 MILES IN HOUR THE CAR DID THE SAME THING. MAZDA TOWED THE CAR TO ANOTHER DEALER. AFTER DIAGNOSIS THEY TOLD ME THAT IS NOTHING WRONG WITH THE CAR AND THE CAR IS NOT UNDER THE WARRANTY ANYMOORE . I TOLD THEM THAT THE ENGINE LIGHT WAS ON AND SOMETHING MUST BE WRONG. THEY DIDN'T RESPOND. THE CAR HAS 24,000 MILES AND I AM AFRAID TO DRIVE IT ANYMORE.
Official recalls

Oct 18, 2016
Mazda North American Operations (Mazda) is recalling certain model year 2017 Mazda6 vehicles manufactured August 12, 2016, to September 28, 2016 and equipped with optional accessory fog lights. Due to an incorrect combination switch being installed, the turn signals may not automatically cancel by the rotation of the steering wheel. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Consequence & remedy
Consequence: A vehicle continuously driven with the turn signal flashing may result in confusion to other drivers, increasing the risk of a crash.
