Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2002 Mini Cooper Owner Comments

  • 50,143 miles


I have a 2002 MINICooper S. the car?S engine cooling system has ongoing issues, particularly the coolant expansion tank. I have had to replace the coolant expansion tank three times within approximately 50,000 miles. This means my car is now on its fourth coolant expansion tank. Here is a short summary of the coolant expansion tanks that my car has had: Date tank installeddate tank failed/replacedcar mileage when replaced when car was builtjune 19, 200414,130 June 19, 2004october 23, 200417,528 October 23, 2004october 24, 200750,143 October 24, 2007not yetnot yet the radiator also failed at 50,143 miles, which is an event I am also not pleased with. Additionally, it now appears--as of September 2008--that I may have another cooling system issue. I will be calling my mechanic soon to check into it. All of these failures of the coolant expansion tank took up substantial amounts of my time in taking my car to the repair shop and then going to retrieve it after the repair. And in one case left me stranded on the side of a very busy California freeway at rush hour. Additionally, I fear that the multiple failures of the expansion tank have stressed the other parts of the engine's cooling system (as evidenced by the radiator failure and the need to replace another coolant part). The local MINIcooper dealer replaced the first two expansion tanks under warranty and declined to replace the third expansion tank. After I complained--and after six months of follow-up calls and letters--they finally reimbursed me for the cost of the third expansion tank. In all instances, MINIdeclined to let me keep the old part--even though I asked each time.
