1 Radiator problem of the 2002 Mini Cooper S

Failure Date: 07/30/2018

Purchased this car used with low miles. Shortly after purchase I noticed the steering on my vehicle got a little harder to steer, didn't think to much about it. Then the radiator fan would not turn off when the vehicle was off. Took the car in to two different mechanics to find the problem. Found out it was the power steering pump went out causing the coolant reservoir to go out. This could cause extreme safety hazards when driving on the freeway and the steering freezes!! I contacted BMW after hearing there was a recall for this same problem. I was told we missed the recall time frame. I have low miles, 60,000. The recall expired in 2017. Well, my care was not having the issues. I don't feel comfortable selling the car and handing the problem to another consumer. This recall should be extended as it could be an unpleasant result.

4 Radiator problem of the 2009 Mini Cooper S

Failure Date: 03/11/2015

A few weeks after I bought the vehicle, I noticed that there was a noise when starting the engine cold. This "rattling" noice would continue until the engine heated up & go away. I took the car in they changed the oil & told me that the coolant was low. He asked if the car was overheating which it was not. He told me to keep a close eye to see if the car overheats. I made an appointment to take the car to a local mechanic just to be safe. A few days later, driving 65mph on the freeway I noticed smoke coming out of my exhaust & the hood, closer to the windshield not the front by the radiator. Smoke started coming from the vents and smelled "rubery". The thermstat symbol appeared & then the oil light. I took it to carmax who said "sry, no extended warrenty, no help". I took it to the local mechanic. He told me initially that the thermostat was blown and there was a material failure of the housing (it was cracked), he replaced all the pipes from the coolant: $482. The mechanic called & said that he could not "burp" the vehicle & that it made a weird sound so they have to "bleed it overnight". This did not solve the issue so they had to take the engine apart & find the problem. The head casket was blown & quoted me a repair bill of $5000+ . The owner of the shop called BMW and asked if they could do a "good faith" replacement which they said they would do if the car had less than 80,000 miles on it. . . Mine had 85,000 miles on it. . . From what I am reading on the complaint board, this is a very common issue!! as a rn if there is a failure in any product we implant in patients, there is an immediate recall, so why, when BMW clearly knows this is an issue do they wait for hard-working people like me to be put in this horrible situation!!! I hope that BMW steps up an honor it's "good faith" beyond 80,000 miles and replace the car.

7 Radiator problem of the 2007 Mini Cooper S

Failure Date: 12/25/2010

As a background, on November 25, 2011, I delivered the car, a 2007 Mini Cooper S to a Mini dealership where I always have it serviced. The reason I brought it in for service was due to the overheating light and engine light being triggered while driving. When I picked up the car, the service advisor assured me that it was in complete working order and the repairs made the car as good as new. On that November 25th, visit, I had paid $1,817. 40 for a new water pump, thermostat, spark plugs, and water pipe replacement despite the fact they are commonly 100,000-mile services. My car has less than 41,000 miles. 10 days after my car was serviced, the same overheating light and engine light came on again. In response to this repeated issue, on December 11, 2011, I spoke with the service advisor who told me to bring the vehicle back to the Mini dealership. During this second visit, I brought the vehicle to the Mini dealership in order to attempt to resolve the overheating issue for a second time. During this second visit, the Mini dealership replaced the fuel pump and flushed the radiator several times, again, in an attempt to solve the overheating issue. When I picked up the car, the service consultant assured me that it was in complete working order and the repairs made the car as good as new. This was the second time that I have been assured that this car was in proper working order. Now, for the third time in the past 24 days, the overheating light and engine light has came on again while I was driving on December 18, 2011. Frustrated, at the least, I promptly returned the car for further service by your dealership. I was shocked when the service advisor contacted me on December 21, 2011 to inform me that an engine replacement was required. The car has fewer than 41,000 miles and has only ever been serviced by licensed Mini dealerships.
