Took my car in for diagnostics due to a 'clicking' noise when starting my car. Just had my alternator replaced and battery was about four months old. After running diagnostics they determined that my battery was the problem. They offered to sell me a new battery for 200.00 PLUS the 85.00 for the diagnostics. I advised them the battery was under warranty so I would take it to Autozone yet the persisted on me getting one of theirs.I took the battery to AutoZone so I took it to get tested and go figure, it was testing ok. So I called Ken's Tire and Auto back to let them know this wasnt the problem, they insisted their checks indicated this was the problem. I then took the car to another mechanic and he determined immediately that the starter was the issue. Ken's Tire and Auto had provided me a printout stating the starter tested out just fine. So after getting the starter replaced the car worked like a champ, no issues at all. I called Ken's to let them know of this and that their diagnostics were way off and inquired on some type of refund. I was given nothing but an excuse that their diagnostics were correct and that they couldnt help me anymore.
