meineke Did not tell me about check engine light that was not on when I pulled in- broke down a block away OXNARD, California

I went for an oil change, left and noticed my check engine light was on- never been on at all before I arrived.  I broke down a block away, chugged back to the shop.  I asked why I was not informed and the "manager" said  "you looked like you were in a rush". I could have been in an accident, luckily not.

They scoped my engine, all of a sudden my fuel pump was damaged- it is a diesel and external from tank. I had my truck towed to the dealer and now face a $1000.00 repair as a result of this unacceptable business ethic.  I had gone to this shop for years with no problem at all, did not even notice it was now Meineke franchise, figured what could go wrong-  I will never return here again, it is a joke how they treat customers.
