i have had my car now for 6 months and it has been in the shop 5 times already total of 2 weeks at a time with coolant level problems. the car likes to be driven very calm once the car is driven hard it looses antifreeze and the low coolant level comes on. mercedes here in ny must have changed everything they told me from pumps to gaskets to hoses and still the same issue whats next?!

It appears that every once in a while some of my coolant seems to dissapear..
