2012 Mazda MazdaSpeed3 4dr Hatch
turbocharged 263hp 2.3L I4 6-speed manual FWD

| 7000 mi US $185 |
battery failure |

| 35000 mi | Lock motor was replaced. |
| 32000 mi | The Headlights pulse and fan blower pulses with changes in engine rpm. I measured the voltage change and I have a 1.5 volt drop that takes over one second to recover. There was a service bulletin to address the pulsing headlights by installing new computer software. I had it performed and it reduced the headlight pulsing some. I took the car back later and the shop rushed me in and out and told me it was normal. I've just been living with it, but it doesn't instill a lot of confidence in the car and its electrical system. |

Battery would no longer hold a charge--replaced battery. |
