1998 BMW 740IL User Comment / Complaint

Low coolant message came on while driving. within a few miles, radiator cap overpresured and steam burst out while on the highway. pulled over and was towed to the dealer. replaced coolant hoses. 4 months later, low coolant message came on again while traveling; stopped at a service station to check level; level was very low, and a slow leak was visible. replaced coolant reservoir assembly. 6 mos later, check engine light came on. dealer replaced sensor. one week later, the low coolant message came on again (3rd time). coolant was low; took to dealer for repair. all work was at owner's expense (non-warranty).
