Car drains my battery and it messed up my alternator. I replaced both and once again my battery keeps being drained. I took it to the shop and the mechanic ran a diagnostic test and about 10 codes popped up saying electrical problem. Other models of this Buick has been recalled for the same electrical problem. Il drive my car and it will completely cut off on me and the check engine light comes on. Il find my paper work from the mechanic if needed. This has been happening for months now. It didnt happen just once. So I cant drive the car until its fixed.
