Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2012 Mini Cooper owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2012 Mini Cooper Coupe. The contact stated that while operating the vehicle, the check engine warning light illuminated, and the vehicle stalled. While inspecting under the hood, the contact discovered that cylinder #4 coil was charred, melted, and smoking, and the ECU was damaged. The vehicle was towed to the local mechanic, who determined that the failure was caused by an inoperable electronic auxiliary water pump. The vehicle was not repaired. The manufacturer and local dealer were notified of the failure, but no assistance was provided. The contact was informed that the VIN was not included in NHTSA Campaign Number: 18V248000 (ENGINE AND ENGINE COOLING). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 55,000.
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.
I was driving and went to brake, but the car wouldn't respond. To avoid hitting another car, I swerved sharply and went up onto the curb. The car started smoking and caught fire.
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/Mini has already taken the life of a driver in south Korea. …

While driving for about 30 minutes on the highway, my Mini Cooper 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 Mini hasn't been worked on since last year when I got new tires, I also keep up with every oil change.
Tl* the contact owned a 2012 Mini Cooper. While driving approximately 20 MPH, the contact crashed into the preceding vehicle after it stopped without warning. The vehicle was merged into a parking lot, where the contact noticed some minor damage to the front of the vehicle and smoke appeared under the hood as a fire started. The fire department extinguished the fire. The vehicle was destroyed. There were no injuries. The manufacturer was not notified of the failure. The approximate failure mileage was 66,000. The VIN was not available.
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. …
These 2012 Mini Cooper clubman are having the timing guides brake and sometimes ruin the engine. In my case I think I caught it on time, I called Mini here locally and my warranty runs out this September 2017 or 100,000. But my car just hit 105,000, this is an issue that Mini have had for quite a few years and I saw a recall up to 2011 but haven't seen anything for 2012 Mini clubman. It's hard to believe that BMW/Mini went 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 $3000.00!to get this fixed. I was driving when I heard the noise and now it sits in my driveway.
