2017 MAZDA MAZDA3 Engine Problems

I have a 2017 Mazda 3 with exactly 59,454 miles. I was driving my car into work and a warning came on saying coolant temperatures high pull over immediately. I feel my safety was at risk since I was on a highway and my car lost power and would not allow me to accelerate. Loaded the car on a flatbed to bring into a Mazda dealership. I had oil leaking into my coolant. They diagnosed it as a cracked cylinder head or engine block. Only solution I was given was to replace the engine with a factory new engine. I spoke to Mazda customer service and they admitted it is a known issue.

ENGINE STALLS WHEN IN MOTION ON HIGHWAY. SAME AS OTHER MODELS ON NHTSA WEBSITE.

ENGINE STALLS; STOPS RUNNING. LOSES TOTAL POWER WHILE DRIVING ON A HIGHWAY. THIS HAS HAPPENED AT LEAST 4 TIMES, BUT MOST LIKELY MORE. MY MAZDA COMPUTER SHOULD HAVE RECORDED THESE INCIDENTS.

THE ENGINE BEGAN REVVING HIGH AS I TOOK MY FOOT OFF THE ACCELERATOR AND APPLY THE BRAKES AS I APPROACHED A TRAFFIC RED LIGHT. I PUT THE CAR IN NEUTRAL TO SEE IF BY TAPPING THE GAS PEDAL IT WOULD STOP REVVING. IT DID NOT. WITH MY FOOT ON THE BRAKE PEDAL TO THE FLOOR, I PUT THE CAR IN DRIVE AND THE CAR SPED FORWARD DESPITE MY FOOT ON THE BRAKE PEDAL. I WENT THROUGH A RED LIGHT TRYING TO MAKE A LEFT TURN ON TO A MAJOR HIGHWAY, CROSSED A MEDIAN STRIP, CLIPPED A VEHICLE IN THE REAR, TURNED THE CAR TRYING TO AVOID COLLISIONS WITH OTHER CARS, WENT OFF THE ROAD HITTING UTILITY POLE AND TRANSFORMER BOX ON THE OPPOSITE SIDE OF THE HIGHWAY, FINALLY COMING TO REST WITH AIR BAGS DEPLOYED ON THE DRIVER SIDE. THIS HAPPENED ON JULY 8, 2018, A SUNDAY AFTERNOON. NO ONE...

MAKING A RIGHT TURN FROM A STOP ONTO A FREEWAY SIDE STREET. IT IS A 50 MPH ZONE. ABOUT HALFWAY THROUGH THE TURN ON LIGHT THROTTLE AT ABOUT 10 MPH, I GIVE IT THE GAS AND NOTHING HAPPENS. THE ENGINE IS STILL RUNNING BUT WILL NOT ACCELERATE. I LET OFF THE THROTTLE COMPLETELY THAN REAPPLY IT. NOW IT ACCELERATES. GAS TANK IS SLIGHTLY OVER 1/4 FULL. THIS HAS BEEN PREVIOUSLY REPORTED TO MAZDA AS IT HAS OCCURRED A FEW TIMES BEFORE. THEY HAD INSTALLED A RECORDING DEVICE IN THE CAR FOR A WHOLE MONTH BACK IN JANUARY THIS YEAR. TODAY WAS THE FIRST TIME SINCE BEFORE THE BLACK BOX THAT THIS PROBLEM CAME BACK. THE CAR WAS PURCHASED IN AUGUST 2017.
