2014 Mazda Mazda6 Driver assistance Problems

At 70000 miles the transmission just got stuck into a single gear in manual. I drove it home and the check engine light came on. Before this problem the car would not go into park. Every time I put it into park I was unable to turn off the car because it thought it was still in gear. I had to fiddle the gear stick. The car also made a high pitch click (metallic) when shifting into 1st or Reverse from park. I took it to Capitol Mazada San Jose and they charged me $7000 to fix some transmission problem. I took it home and the clicking noise did not go away. I took it back to the dealer and they redid some work.

The car had a (SUA) Sudden Unintended Acceleration malfunction. No, the car was totaled and towed away. My safety was put at risk as I was slowly pulling into a parking spot, eased my foot onto the brake and this malfunction caused my car to involuntarily jolt into a rampant high speed. It jumped a curb and crashed into a tree. My brake was useless in stopping this runaway vehicle. The only thing that stopped it was that tree! The airbag deployed and I was badly bruised from the airbag. Fortunately, there were no pedestrians or other cars near mine. There were no warning lights or messages before, during or after the accident. It happened so quickly because the tree was only a few feet in front of my car.

FOR SEEMINGLY NO REASON, THE VEHICLE WILL RESTART AND STALL WHILE DRIVING AND MULTIPLE WARNING LIGHTS WILL ILLUMINATE. THIS HAS HAPPENED WHILE DRIVING SLOW, FAST AND WHILE TURNING. WHEN THIS HAPPENS, I NEED TO IMMEDIATELY PULL OVER AND RESTART THE ENGINE. THE CHECK ENGINE LIGHT TURNS ON AND INDICATES AN ABRUPT VOLTAGE CHANGE ISSUE, BUT SOON TURNS OFF AFTER A FEW POWER CYCLES. THIS STARTED TO HAPPEN MORE AND MORE OFTEN, AND MORE RECENTLY, I HAD THE CAR NOT ABLE TO START AS IF THE BATTERY DIED. ALL MY ELECTRICAL COMPONENTS, SUCH AS HEADLIGHTS AND HAZARD LIGHTS SHUT OFF AND AFTER ABOUT 10 SECONDS, THEY ALL TURNED BACK ON AND RUNNING NORMALLY. AT THIS POINT MY VEHICLE STARTED UP AGAIN JUST FINE. THIS HAS NEARLY CAUSED AN ACCIDENT A COUPLE TIMES AND NO MECHANIC HAS BEEN ABLE TO DIAGNOSE THE ISSUE YET. ALTHOUGH, THIS ISSUE SEEMS ALARMINGLY CLOSE TO A RECENT RECALL THAT WAS ANNOUNCED FOR 2018-2019 MAZDAS RELATING TO A SOFTWARE ISSUE THAT CAUSES UNEXPECTED ENGINE STALLING RELATING TO THE FUEL-SAVING CYLINDER DEACTIVATION TECHNOLOGY. UNFORTUNATELY, EVEN THOUGH MY VEHICLE CONTAINS THE SAME TECHNOLOGY, IT WASN'T INCLUDED ON THIS RECALL LIST.

INTERMITTENTLY, THE CRUISE CONTROL BUTTONS DO NOT PERFORM THEIR PROPER FUNCTION. WHEN EXPERIENCING THE ISSUE, ALL OF THE FOLLOWING OCCUR: 1) CANCEL BUTTON FUNCTIONS AS THE MINUS (DECELERATE) BUTTON, 2) THE MINUS BUTTON FUNCTIONS AS THE PLUS (ACCELERATE) BUTTON, 3) THE PLUS BUTTON DOESN'T WORK, AND 4) THE OFF BUTTON DISENGAGES THE CRUISE CONTROL BUT DOES NOT SHUTOFF THE CRUISE CONTROL MAIN POWER. THIS BEHAVIOR IS AN ISSUE BECAUSE WITH THE CANCEL BUTTON ACTING AS THE MINUS BUTTON, THE CRUISE CONTROL WILL ACTIVATE WITH THE CANCEL BUTTON. IN ADDITION, HAVING THE MINUS BUTTON FUNCTION AS THE PLUS BUTTON COULD CAUSE AN ACCIDENT IF THE CAR BEHAVES IN THE OPPOSITE MANNER AS EXPECTED. THE ISSUE OCCURS INTERMITTENTLY WHILE DRIVING.

WITH NO CONSISTANCEY, THE CAR WOULD LOOSE POWER. AT TIMES, I THOUGHT THE CAR WOULD LOOSE FULL POWER, IN THE MIDDLE OF MY COMMUTE, I WOULD BE FORCED TO PULL OVER AND SHUT THE CAR OFF. MOST TIMES, THE CAR WOULD RETURN TO NORMAL CONDITIONS. WHEN I BROUGHT IT IN FOR REPAIR, BYERS MAZDA OF COLUMBUS, TOLD ME IT NEEDED A TUNE-UP. ONCE AGAIN, THE CAR ALMOST STALLED OUT AND I MANAGED TO COAST INTO A PARKING SPACE. NOW THE SAME DEALERSHIP IS INFORMING ME FOR THE FIRST TIME THAT THE CAR HAS AN I-LOOP SYSTEM AND THE BATTERY THAT SHOULD HAVE LASTED FIVE YEARS, NOW LESS THAN THE 3 YEARS OLD, NEEDS TO BE REPLACED FOR OVER $500.00. I BOUGHT THIS CAR USED WITH AN EXTENDED WARRANTY AND ALTHOUGH IT WAS MY MISTAKE, THE DEALERSHIP NEVER DISCLOSED THE I-LOOP SYSTEM AND THE PROBLEMS THAT GO WITH IT. THIS I-LOOP BATTERY WILL APPARENTLY LAST 2-3 YEARS ONLY AND IS VERY EXPENSIVE. I GUESS IT IS LEGAL FOR DEALERSHIP SALES REPS TO MISREPRESENT THE CAR MAINTENANCE BECAUSE THEY SAY IT IS MY RESPONSIBILITY TO KNOW WHAT I PURCHASED. I WILL NEVER BUY FROM BYERS AUTO FOR ANY MODEL CAR!

WHILE DRIVING ON THE HIGHWAY WITH CRUISE CONTROL ON, MY CAR ATOMATICALLY SLAMMED ON THE BRAKES AND SLOWED DOWN RAPIDLY. A SHORT TIME LATER, THE FORWARD OBSTRUCTION WARNING INDICATOR CAME ON AND SAID AN INSPECTION WAS NEEDED. MAZDA DEALERSHIP SAID "NEVER HEARD OF THAT" DESPITE SIMILAR PUBLIC COMMENTS ON USER FORUMS. DEALER WILL NOT COVER FULL COST OF THE REPAIR BECUASE CARE IT OUT OF WARRANTY. I BELIEVE THIS IS A SERIOUS SAFETY ISSUE THAT SHOULD NOT FALL UNDER NORMAL WARRANTY CONSIDERATIONS.

I WAS DRIVING DOWN A STREET @ 40MPH WHEN THE INFOTAINMENT, SPEEDOMETER, SHUT OFF AND I COULD NOT ACCELERATE. THE STABILITY CONTROL WARNING CAME ON AND STAYED ON. AFTER A BRIEF MOMENT, THE STABILITY WARNING TURNED OFF, BUT THE CHECK ENGINE LIGHT WENT ON. THE CAR DROVE NORMALLY FOR THE REST OF THE DAY, BUT THE VERY NEXT DAY, AT A STOP LIGHT, THE SAME THING OCCURRED, BUT THIS TIME, I COULD NOT ACCELERATE PAST 2000 RPMS, NOR REACH 20 MPH. I PULLED OVER ON THE SIDE, AND TURNED OFF THE CAR. THEN TURNED IT BACK ON. IT DROVE NORMALLY WITH THE CHECK ENGINE LIGHT ON THE REST OF THE DAY, BUT THIS COULD BE A VERY DANGEROUS SITUATION.
