Ron - The 55 is 73k on it. It was the break line the ruptured due to some type of rubbing against another line. I had the PS pump replaced 2 weeks ago and thought it may be related. I just recieved a call from the service manager and the want to knock off $300 bucks. If it wasnt an emergency i would have taken it to my own Authorized Dealer. And yes the care has always been serviced at MB
