| 63000 mi | I randomly checked my coolant level on a cold Christmas Eve and discovered my coolant level was extremely low below the low fill line on my coolant reservoir. This car has been dealer maintained as its a CPO, and according to my paperwork the coolant level had been checked by the dealer 2 months prior. Fearing a coolant leak I had the dealership perform a leak test and none was found. Additional coolant was used to top off the level and according to the service dept the temperature drop caused the coolant to contract. This inspection was completed free of charge. |

Upon replacement, dealer told me the bearing was "definitely bad" and I had been right to replace the pump. |

The cam chain housing was weeping oil. The Mazda dealer found this around 45,000 miles and advised me that it would cost around $850 to repair. They didn't say it was covered under warranty. Since the oil wasn't dripping and the oil level wasn't going down, I declined to have the repair done. I returned to the dealer after the warranty was up (just after 50,000 miles) and the dealer said they would fix it under warranty. They said that the hydraulic tensioner for the serpentine belt was leaking. I told them to fix the slight leak in the cam chain cover, and also replace the hydraulic serpentine belt tensioner, and replace the serpentine belt while they were at it. The replacement of the hydraulic serpentine belt tensioner and the new serpentine belt cost me around $210. |

Car was idling roughly and had occasional problems cranking up. Like it would take longer to crank before the engine fires up. It almost sounds like the enginr was choking before starting up. Car would idle roughly but only after the engine has warmed up. Dealership did not diagnose the car, but suggested throttle body and intake valve cleaning, valve cover and spark plug replacement. The idea was these services would fix the problem. After having all of those done, the issue with idling roughly has gradually gone away. It doesn't seem to an issue anymore, today is like 1 month since the car was worked on. The car still has the occasional issue of trouble starting up. Same symptoms, it takes longer to crank before the engine fires up. Only seems to happen when the engine is warm, has not ever happened yet on a cold start. I am working around this issue by stabbinh the gas pedal as soon as i notice the car taking longer to fire up. |

Strange loss of ignition while driving, just for a split second, then ignition returns. Happens mostly during slight right turns, when right turn signal running. Very hard to reproduce, but happens more frequently at night when lights and other electrical on. Mechanic thinks it's in the steering column where ignition wiring and modules are. Haven't fixed it. Just trying to analyze exact cause. Must reproduce at-will to fix. Have to take out steering wheel. Too much hassle at the moment. Will diagnose over time. Car runs pretty much great except for those sporadic loss of ignition like the car goes off the "on" position. Not related to the ignition slot or key. Can pull and push on it with no effect. Not weight pulling key downwards either. Mostly when steering wheel is slightly to the right and right signal running. Very strange. |
| 72000 mi | Very intermittent problem. While driving, getting very short periods of hesitation, total ignition failure and lighting off but ONLY for a split second, then it returns to ignition and all electrical running and keeps going with no issues. Seems like a bad ground issue that only occurs under certain conditions and movement. Gets worse in rain/wet conditions. Very difficult to troubleshoot. Seems like an issue in the steering column/ignition circuit, and generally happens more when the headlights are on. Very short period of single loss of total power, for milliseconds, hesitates and then comes back on like nothing ever happened. I just hope it's not in the ECU or a connector to the ECU. This will take time to troubleshooting. Will post updates. Doesn't happen very often, maybe once a week. Will first have to tighten down all ground wires and go from there. |

Car has a low idle (around 500 RPM) and shakes and almost stalls at red lights, once the engine is warmed up. The Mazda dealership cleaned the throttle body and replaced engine mount #3, at my expense, with NO improvement in symptoms. Follow up visit for my low idle/shaky idle/almost stalling at red lights, after I paid them good money to diagnose and fix the problem. They claim the idle is just fine and there is no problem.
