Check engine light appeared then I had a dead battery. I purchased a new one and the check engine light went away for a while until now. Then I found a letter online that I never received of a recall for california vehicles that were manufactured during specific dates. Mine is listed as one but it does not have an active recall.

Dealer service tech stated the high pressure and low pressure fuel pumps failed and needed replaced. My car was not included in the recall regarding fuel pumps for Mazda, so the dealer would only cover 50 percent of the cost. Service tech and warranty service rep stated that Mazda was aware that what happened to my car is a factory malfunction but because my car is out of warranty they would not cover the entire expense. My car is 3 years old and only has approximately 67,000 miles on the engine. The fuel injectors were replaced at 10,000 miles by warranty. The service tech even stated this is obviously regarding the recall of the fuel pumps and did not understand why my car was not included.

FROM A FULL STOP AND FOOT ON THE BRAKE PEDAL, MOVE FOOT TO HIT THE GAS PEDAL AND A DELAY OR LAG IS EXPERIENCED ABOUT 50% OR MORE OF THE TIME. THE REGIONAL MAZDA EXPERT AND DEALERSHIP HAVE VERIFIED THE PROBLEM AND NOTHING BUT EXCUSES WHY THEY CANNOT FIGURE OUT HOW TO FIX IT HAVE BEEN STATED, THEREFORE I HAVE BEEN LIVING WITH IT FOR OVER 20K MILES ON A NEW CAR. WHILE STARTING FROM A FULL STOP AND FORGETTING ABOUT THE DELAY IN PROPULSION, IT HAS CAUSED SEVERAL NEAR-MISS ACCIDENTS FROM ONCOMING VEHICLES. WHEN I HIT THE GAS PEDAL, I EXPECT THE CAR TO MOVE FORWARD!! THIS IS DANGEROUS!! THE DEALERSHIP DOES NOT HAVE A SOLUTION AND IS POINTING TO MAZDA JAPAN FOR A SOLUTION, BUT NOTHING FOR OVER A YEAR NOW.

JAN. 23, 2020. 10:45 AM. I WAS ON MY STREET, A NARROW RESIDENTIAL STREET, PREPARING TO BACK IN MY GARAGE. IN ORDER TO DO THAT ON THIS NARROW STREET, I TOUCHED THE LIP OF THE DRIVEWAY ACROSS THE STREET. SPEED WELL UNDER 3 MPH. WHEN I DID SO, MY CAR SUDDENLY SHARPLY ACCELERATED AND AT THE SAME TIME SWERVED TO THE RIGHT. THE ACCELERATION AND SWERVE DROVE THE CAR INTO THE TOWNHOUSES ACROSS THE STREET FROM MY HOUSE. THE DRIVEWAYS ARE VERY SHORT, BARELY A CAR'S LENGTH. AFTER CRASHING, I COULD FEEL THE CAR STILL ACCELERATING. I QUICKLY SWITCHED THE CAR INTO PARK AND THE SPONTANEOUS ACCELERATION CONTINUED. IN ORDER TO STOP IN I HAD TO TURN THE CAR OFF. WHEN THE TOWING COMPANY TURNED THE CAR ON LATER IT IMMEDIATELY STARTED TO SPONTANEOUSLY ACCELERATE AND SURGE FORWARD AGAIN. THE MAZDA DEALER AND INSURANCE INSPECTOR EXPLAINED TO ME THAT THERE IS A SENSOR: WHEN A WHEEL ENCOUNTERS WHAT IT PERCEIVES TO BE AN OBSTACLE, IT 'TOSSES' ALL THE POWER TO THAT WHEEL AND ACCELERATES. THESE DRIVEWAYS HAVE A SMALL LIP AT THE EDGE. THIS SENSOR REACTED TO IT IN A WAY THAT CAUSED MY CAR TO CRASH. THE CAR WAS TOTALED AND THE TOWNHOUSES ACROSS THE STREET DAMAGED. THANK HEAVEN THERE WAS NO ONE OUTSIDE OR THEY WOULD HAVE BEEN KILLED. THIS NEEDS TO BE INVESTIGATED, RECALLED AND CHANGED.
