Help me troubleshoot mazdaspeed 3 problem
 

Hey Guys,

I have 2010 mazdaspeed 3. I have taken it to the dealership twice with this problem and they haven't been able to fix the problem. So hopefully you guys have some ideas.

Here are the symptoms:

• Long cranking (intermittent, but pretty consistently)
  car dies very fast if I leave the lights on or radio on. within an hour it will be completely dead.
  lights dim when I turn the wheel
  every now and then the CEL comes on and the traction control light stays on and the car won't go out of idle. Haven't able to read that code yet. This could be an unrelated problem from the above.

Last time I took it to the dealership they reset the computer and said that it would be fixed. They say the battery tests fine. But I don't know, replacing the battery might be a good start.

anything helps guys, Let me know any advice you guys have.

Thanks,

definitely start with replacing the battery. and prepare for flaming.

Replace battery.

Replace battery. Check for the usual shit draining the battery.

Will do. Thanks guys
