Got a call from a local dealer today turns out they put washer fluid in my antifreeze overflow tank. They assure me I have not had it in there very long it looks like it happened at my last oil change with them. TWO F-ing months ago. I THINK IT COULD HAVE BEEN LONGER I HAVE BEEN IN AND OUT OF THAT SHOP AT LEAST 10 times. Chrysler wants nothing to do with it. I am still under factory warranty but they told me this may void my 8 year 80,000 extended service plan. They also told me I need to take it up with the dealership who I have had nothing but problems with. I saw my car today torn apart because of fixing a condenser or and evaporator to get rid of the ac smell. With my steering wheel sitting on the shop floor face down. Not happy need thoughts on how far I should take this. My brother is the head of parts there he is not happy and we are also friends of the family with the owner. HELP what can I do what do I do? Is this going to hurt my car in the long run?
