Thank you for allowing me to help you with this concern today and am sorry to hear that this is happening. I will have to ask you a few questions so that I can get a better understanding as to what may be going on with your Impala.

It sounds like you just bought this Impala, correct?

What have you tried so far, have you been to a repair shop? or what items have you replaced?
