This car was maintained, by Mini and BMW authorized mechanics and only had OEM parts installed and followed management of vehicle as directed by manufacturer, throughout its history. It was always driven and kept in moderate weather conditions, no extreme heat, cold, wet, or speeds. Used almost daily for 30-60 minute commutes. Just after 100K miles, total engine failure was suddenly experienced on the freeway, due to combustion in two valves, damaging two cylinders and sudden leaking of the exhaust system under the hood. The manufacturer, BWM, has been shown evidence of malfunctioning of the four cylinder engine and will not show evidence of their grounds for why they will not take responsibility.

My mother who owns this 2012 MINICooper has suddenly now started having issues with her water pump leaking. I took it to the dealership and was treated with this rude employee by christopher guzman whom had a very unprofessional and no empathy. Very short with responses and sarcasm.keep in mind my mother is elderly and knows nothing about cars. So I log into to your site and see there is a recall on water pumps but my mother's is not one of them. And guess what her warranty just expired March 2019. Go figure. So if something would have happened to my mother because of defective water pump. And how funny how my moms car was not a recall. I would qualify for that action lawsuit. How does a 2012 water pump just give up with very low mileage 24 000 I would like to escalate this further and an explanation how this could have happened!! look at the milage!

While driving for about 30 minutes on the highway, my MINICooper shut off completely, I was able to pull onto the shoulder and that is when smoke started coming from the engine, within 6 minutes my whole engine was engulfed in flames, car totaled. Insurence inspectors couldn't figure out a cause. One of the fire fighters said it looks like it started near the water pump. There are recalls on other models for this problem, but not mine. My MINIhasn't been worked on since last year when I got new tires, I also keep up with every oil change.

Vehicle was in motion on a highway and, after going over several pot holes, the engine temperature warning light came on. The engine power was reduced, and the engine failure light also appeared. This is when I pulled over into the off ramp, and the vehicle came to a sputtering stop. I placed the car in neutral and pushed it to the dirt side lane of the off ramp. I opened the hood, smelled something burning, and saw smoke coming from the engine. I could see burnt circuits, burnt plastic, and coolant leaking all over the engine and exposed wiring. Had it not been for immediately exiting onto the off ramp, the vehicle would have stopped in the middle of the highway without warning. I could have almost died because of the fire; this faulty engineering by BMW/MINIhas already taken the life of a driver in South Korea. BMW issued a recall of the 2012 MINICooper S roadster in South Korea, but when I had the car towed to one of their service centers, the technicians were unaware of this manufacturing defect and stated that the repair parts are unavailable. I see that my vehicle has been recalled, but when I type in my VIN, no recall is attached to my vehicle. BMW/MINIis taking no action; they are harming and killing drivers of its vehicles.

Temperature sensor in radiator hose leaking. Needs upper radiator hose, and thermostat with harness to correct. Discovered during a routine oil brakes etc inspection by the dealership. I was told there was a change in the harness and the new one has a "computer" and would cost $1450 to fix. This is an upper hose and I looked online and found the replacement harness has tow separate connectors, one for coolant temp sensor and the other for the coolant thermostat. I hd checked my fluids two days before on a cold engine and they were fine and water overflow was at the proper level. I checked my coolant overflow tank the day after visiting the dealership on a cold engine and the overflow tank was low... I added water... it has not gone down for several days. I have heard there is corrosion that happens and the thermostat may not employ and you can have an overheated engine.

These 2012 MINICooper clubman are having the timing guides brake and sometimes ruin the engine. In my case I think I caught it on time, I called MINIhere locally and my warranty runs out this September 2017 or 100,000. But my car just hit 105,000, this is an issue that MINIhave had for quite a few years and I saw a recall up to 2011 but haven't seen anything for 2012 MINIclubman. It's hard to believe that BMW/MINIwent with plastic guides instead of some other material that could withstood more beating, specially for this area. Thank you for any help, because I'm having to fork out any wheres between $1500'to $3000!to get this fixed. I was driving when I heard the noise and now it sits in my driveway.

Water pump failure. Began to notice small amount of liquid under car in April 2016, thought it was condensation from A/C. leak worsened and called MINIin June 2016 to check it out. Water pump failure on vehicle with 45,500 miles. Class action lawsuit settlement agreed in California in March waiting on final approval of terms due in November 2016. BMW knows this is a defective part. Water pump failure from defective part could have catastrophic effects if automobile is in motion at any speed.

Driving 45 mph on busy city four-lane road, I braked gradually in approach to red light, which is my normal braking style. Car did not come to a complete stop--brakes only worked to a point but did not completely stop car; simultaneously engine revved to very high RPM. I threw transmission into park and turned off ignition lest my car Ram car ahead of me. Very frightening. At previous two lights I had noticed that brakes were acting funny, not bringing car to a complete stop but I had left plenty of braking distance and was able to let car roll to a stop, in spite of brakes not effecting a complete stop. At those two lights the runaway engine (high RPM) did not occur or I would have pulled over right then. However, engine revving to high RPM has also occurred occasionally when pulling into garage but I had not given this a lot of thought because I have quickly turned off ignition. Now I know it's very dangerous situation. Of course I am not driving it but am having it towed to dealer for repair. The car has been serviced regularly at dealer and has 24,239 miles on it. There has never been a necessity for repairs on this MINICooper clubman.

Purchased a certified pre-owned MINInext 2012 clubman 6-speed with 6,498 miles on it 08/2013. * 10/14/2013 around 9K miles lost power on the highway and went into limp mode, maneuvered to side of highway and called roadside assistance. Towed car in to dealer who replaced 4 spark plugs said all was ok. * 10/17/2013 I pick the car up, get 3 miles from dealer on interstate and the car does it again so I maneuvered off the closest exit and called roadside assistance. Towed back into dealer and they kept car until 26th. They said the dme was bad and replaced it and 4 fuel injectors. * 10/30/2013 car did it again and I drove home in limp mode, car was shaking and sounded like a 1970 VW beetle, nearly died at every idle, rough, acceleration and I called roadside assistance and they had car towed from my driveway back to dealer./5/2013 dealer still has car.
