My truck sat for a while I charged the Batt. I drove to the landfill in Tehachapi Ca. It ran fine. I unloaded the trash the engine idled for 30+min. The landfill had debris on the ground. The truck ran fine back to town. I had 3/4 fuel. I decided to fill up at the Loves gas station I filled it all the way 2 clicks I think. I started up the truck after fueling it ran terribly I had a flashing check engine light. I drove home 2milles when home the truck was on 🔥 FIRE!! I turned off engine. Put lots of h20 on fire. Disconnected Batt put more h20. I don't know if it started at gas station or in between. I can ask neighbors. The fire was under the driver's seat underneath the truck. I don't know if it was damaged by debris at the dump there was lots of [XXX] on the ground. It has not been inspected yet. I have not started any repairs. No police report. No damage to any one or property (except my truck). It is in my driveway and can be inspected there or towed. No pictures but I can take some. I am glad it didn't cause the gas station to go up in flames. Yes I have it insurance. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
THE ELECTRICAL SYSTEM SHUT DOWN WHILE I WAS DRIVING, TURNING OFF AIR CONDITIONER, RADIO, INTERIOR LIGHTS, AND TURN INDICATOR. THE DASH LIT UP ABS, AIRBAG, AND CRUISE CONTROL INDICATORS. WHEN I STOPPED, I TURNED OFF THE ENGINE AND TURNED THE KEY TO POWER WITHOUT STARTING ENGINE AND FOUND THE ELECTRICAL WORKING AGAIN. I TRIED DRIVING AGAIN AND THE ELECTRICAL SYSTEM WORKED FOR A SHORT TIME AND WENT OFF AGAIN. WHEN IT FIRST HAPPENED, I WAS DRIVING STRAIGHT ON A CITY STREET

Transmission

From owner reports, verbatim
MY 2003 MAZDA B3000 PICKUP SPONTANEOUSLY SHIFTED FROM NEUTRAL INTO REVERSE AND CRASHED THE (DRIVER'S SIDE) OPEN DOOR INTO THE INSIDE WALL OF MY GARAGE. THE VEHICLE WAS IDLING AND UNOCCUPIED, AND THE PARKING BRAKE WAS NOT ENGAGED. THE FORCE OF THE CRASH WAS ENOUGH TO BEND THE DOOR. I CALLED THE LOCAL POLICE DEPARTMENT, BUT WAS INFORMED THAT THEY DO NOT ISSUE REPORT NUMBERS FOR MINOR LOSSES INCURRED ON PRIVATE PROPERTY. I AM FILING THIS REPORT IN VIEW OF THE POTENTIAL FOR SERIOUS BODILY HARM, DEATH, OR MAJOR PROPERTY DAMAGE ASSOCIATED WITH A SPONTANEOUS SHIFTING FROM NEUTRAL INTO A GEAR, SO THAT THE VEHICLE TRAVELS WITHOUT ANY OCCUPANTS, AND POSES THE RISK OF CRASHING. *TR
SUDDEN AND UNEXPECTED LOSS OF CLUTCH FLUID RENDERING VEHICLE INOPERABLE (LOSS OF CONTROL TO GO FORWARD AND GET OUT OF THE WAY) DUE TO AN INABILITY TO SHIFT GEARS. LEAK AT CLUTCH SLAVE CYLINDER IS SUSPECT. FOUND MYSELF TO BE A "SITTING DUCK" AT A TRAFFIC INTERSECTION ALTHOUGH FORTUNATELY, NO ACCIDENT OCCURRED. *TR

TAKATA RECALL IS NOT BEING DONE FAST ENOUGH. THIS RECALL BEGAN OVER A YEAR AGO IN JANUARY 2016. WE HAVE YET TO RECEIVE A LETTER TELLING US TO SCHEDULE AN APPOINTMENT FOR REPAIR.

WE NEED TO GET TO WORK IN THIS VEHICLE EVERY DAY. UNACCEPTABLE.

I WAS DRIVING INTO THE MOUNTAINS OF NC FROM SC. SMELLED SMOKE. REALIZED IT WAS COMING FROM IN BETWEEN TRUCK CAB AND BED. IT WAS VERY DIFFICULT TO PUT OUT FIRE AS IT HAD STARTED TO MELT THE PLASTIC BED LINER AND PLASTIC GAS TANK. FIRE WAS CAUSED BY A 2 FOOT BY 2 FOOT PIECE OF CARDBOARD THAT HAD FALLEN DOWN BETWEEN BED AND CAB. IT WAS RESTING ON THE GAS TANK AND LEANING TO THE SIDE ON TOP OF THE MUFFLER. I ASSUME IT CAUGHT FIRE AS WE TRAVELED SLOWLY UP THE WINDING ROAD. (HWY 276) THERE IS NO SHIELD OVER THE MUFFLER. WHEN THE TANK WAS REPLACED IT WAS REPORTED TO ME THAT THE FIRE HAD MELTED THE TOP OF THE FUEL PUMP AND HAD EXPOSED A HOLE IN THE GAS TANK. I BELIEVE THIS A VERY SERIOUS PROBLEM THAT NEEDS TO BE DEALT WITH BY MAZDA. *JB
