I am not one to rant so I will keep this brief and objective in response to the tirade above.
Customers are stupid? How about dealers. Here is a list of stupid mistakes that I have personally experienced:
1- Lug nuts not tightened on wheel rotation.
2- Charged for R-12 recharge on an R-134 refrigerant system. When I informed the service writer I was TOLD that I was wrong. I lifted the hood and showed them the sticker (R-134 refrigerant). I was offered a free oil change and a refund the difference in price on the refrigerant (about $78.00).
3- Asked for radiator hoses to be changed and they changed the wrong hoses!!!
4- I asked for the EGR valve to be "checked" after a check engine light code yielded an EGR problem. They never checked it, just replaced it ($200.00). When the check engine light returned they discovered it was just a blocked hose. When I asked if they ever checked the EGR valve before replacing it all I got was a blank stare and then an accusation that I asked for it to be replaced.
There is more but I said I would be brief. After all I am just a stupid customer. What do I know?
