While traveling north on us 221 from bent mountain, va to roanoke va my hydralic steering totally failed. As I travelled a short distance my brake light warning lights, abs light, other brake system light, battery light and air bag warning light came on. I looked at the engine temperature guage and the temp was normal. I pulled into a parking lot, raised the hood, checked the fluids in the engine compartment and reentered the car. While sitting in the drivers seat I heard a loud explosion, looked forward and noted thick steam coming from the engine compartment. I turned the engine off, exited the car and when the steam dissipated I noted that the cooling system filling/overflow tank was split in half damaging a protecting cover on the firewall and sprayed a building wall and window with engine coolant 10 feet away in front of the vehicle. I had the car towed to martin's german service in cave spring, va. Because the closest dealership in located in north carolina 150 miles away. Due to service volume they will not be able to evaluate the problem until 24 may 2016.
I own a 2003 Mini Cooper automatic and I've already had to have the power steering pump and the cooling fan replaced twice, and now, only a year later after my 2nd replacement and a few thousand dollars later, it needs to be replaced for a third time. The care only has 80,000 miles on it. This is costly and a safety issue for drivers. I will never buy another car by Mini or BMW.
My 2003 Mini Cooper has almost caught on fire several times, replaced transmission, electrical harness, power steering pump, a/c hoses and a/c service, wheel bearings, injection plugs etc. . . . . . . I still cannot find the real problem why is causing a short, it has almost caught on fire several times, this car has been the most dangerous car I have ever own, I have never spend so much money on trying to fix any vehicle, right now I'm about $11,500 in costs of repairs, this is a crime to the consumer, I have been reading about a class action lawsuit that is in progress, I hope and pray that we get justice from the maker of Mini.
