I know vehicle repairs can be stressful, I do apologize that you had to return for further repairs. Maybe there was some confusion or we did not explain the initial service properly as I did check your repair order and I see that we Initially recommended all the coils be replaced on the first visit which would have prevented you having to come back a month later when the rest of coils failed. We do understand that cost can be a factor but we always recommend a complete repair to prevent your return for more of the same work. I hope this explains the need to return to have more components replaced.
If you do have any questions please feel free to contact me anytime as your complete satisfaction is always our # 1 concern.
