It started about eight thousand miles where I noticed a little hesitation. Check engine light came on and one ignition coil was replaced. Two weeks later felt hesitation again and loss of power.

About a week after I took it in I connected a scanner to the car and retrieved two diagnostic codes with out the check engine light being on. I think these codes could be the problem because they have to do with low voltage. I told the dealer about what happened and they told me that they know about the codes but they can't fix it if the check engine light is not on. That's what's happened so far. *Tr
