Selected complaints filed with NHTSA by 2008 Mini Cooper owners, lightly cleaned up (personal details are redacted by NHTSA).
About two weeks ago while driving on a major highway the mini cooper suddenly died without warning. The power steering quit making the vehicle extremely difficult to steer. The car would not start. The only thing I could do was push it off the road which I did with the help of a person behind me.i had the car towed to my local import shop. They found that the motor had skipped time causing catastrophic engine failure. If I had been going faster my safety would be in jeopardy as well as other motorists. I have since learned that mini's with the N14 engine regularly experience timing chain failure causing this. I have the invoice from the shop identifying the problem. I have checked for a warning or recall from Mini and found nothing. No warning light or msg was visible.
While driving the car at aproximately 25mph, the engine and the car stopped running. All dashboard warning lamps were off prior to the engine failure The car rolled to the side of the road to get out of the way of other traffic. The service engine warning lamp was on after the engine shut off and stopped running. The car was towed to a service station, and they too could not get the car to start. The mechanic's troubleshooting ultimately found the engine's internal timing chain had broken, causing multiple of other internal engine components to become damaged. The engine required detailed repair to replace the damaged engine parts to get it to start operating again. The costs for the repairs were over $5000.00.

In the spring 2014 I purchased a 2008 Mini Cooper 2d hatch with around 98,0000 miles for $14,000 with warranty in ivrington, nj from springfield auto group auto sales. In January 2015 I had a tune up done and the mechanic reported to me after doing a engine diagnostic test that there was a problem with my immediately reported the problem to my warranty company that was provided through my the car loan company credit acceptance. The warranty company refused to pay for engine to be dropped out of the car to find out what the problem was. They advise me that I would have to pay for the engine to be dropped out of the car to be and checked out before they pay for anything. In October 2015 the Mini Cooper engine finally broke down while driving I had to pulled it over while driving up route 280. The wrecker service took the Mini to a mechanic. …
In September, 2013, my 2008 Mini Cooper hardtop, with the n12 engine, had the timing chain fail under operation. This caused the engine to stop, at highway speed, affecting steering, braking and all ability to maneuver the vehicle out of traffic. Two vehicles barely avoided my disabled vehicle. I contacted Mini USA and they refused to acknowledge the factory defect in the timing-chain tensioner that causes the timing chain to fail. I paid over $8000 for a replacement n12 engine. With less than 10,000 miles on the replacement engine, in July, 2016, the timing chain failed again. This time the vehicle was crossing a bridge and there was no place to try to pull off. The situation was very dangerous and left my family vulnerable to oncoming traffic. …
While traveling on the highway in dickson, tn my 2008 Mini Cooper lost all power without warning. I was able to make it to the side of the highway. This was during an ice storm. We had to wait hours on the side of a highway with no heat, and vehicles struggling to stay on the road, until a tow truck driver from aaa was able to pick us up, saying how lucky we were to have not been hit. When bringing the vehicle to a certified Mini dealership I was told that it was due to low oil level. The incident occured in February, my oil was changed on December. Upon repair from my independent mechanic, the cause of failure was determined to be a catastrophic engine failure due to a faulty timing chain that collapsed. I have been made aware that Mini Cooper is aware of the timing chain defect, and in fact sent out a service bulletin but has done nothing to fix this problem. …
On 15 aug 2015 I purchased a 2008 Mini Cooper 2d hatc with 122,629 miles for $6,325 with no warranty in stanford, nc from karas auto sales, inc. On 27 oct 2015 the Mini Cooper broke down while driving and pulled it over beside the road. The wrecker service took the Mini to a mechanic. The mechanic stated the timing chain had broke and there was major engine damage and the repair bill will be from 8K to 10K in repair cost. Mini had approximately 125K miles on it. I've heard of a lot of complaints with those minis with those same issues happening anywhere from 30K miles to over 100K miles from 2007-2010 models. Nothing else has been spent on the car for repair. I'm not wasting anymore money on that junk Mini Cooper. It's to late for the lemon law to be applied. …
Purchased from carmax (11/18/17), never informed of class action lawsuit involving the timing chain with this vehicle. After only 4 months and only a few hundred miles, the problems began. First trip to mechanic, the engine valve cover was found to be cracked. Replaced for just over $700. Less than 10 months later and well under 2000 miles, I was in transit to work, on the highway off ramp and the Mini shut down completely, would not start back up. Had to be pushed off the road. Towed back to auto mechanic and another $200 to find the guide to timing chain broke off, causing engine failure. Mini was towed back to carmax to find the engine needs replaced, but will have to be replaced with the same type of engine, which can cause the same problem to happen again and again. Senior team at carmax is currently evaluating my case. Possible buy back of vehicle, still awaiting a verdict.
"death rattle" noise coming from engine compartment as reported by many others on online forums. Now engine is throwing codes indicating crankshaft out of position. Obvious related issue to a defective timing belt or tensioner. Told by dealership not a covered repair, although I've read that similar repair has been covered by manufacturer for others and for other models. As this vehicle is being driven by my young daughter, out of state, I am very concerned about a complete engine failure whilst she is on the highways in the mountains where she lives, with the potential for tragic consequences. Please consider this issue as a serious potential life safety issue, as a failure at highways speeds could certainly endanger not only my daughter, but the lives of others on the highway. Thank you.
I was driving around and I began loosing power to my car, so I stopped and then I couldn't get it started again. I was in the process of calling a tow company when I popped the hood and when I lifted it up I could smell gasoline and noticed a cloud of fumes so I backed up and it caught fire so I called 911 and now my cars virtually gone. I come across some Mini Cooper owners club forum and its apparently happened to other people and also on youtube. Or it seems like it was the same thing since they caught fire in the engine first too. I called Mini and they are going to have me tow it there so they can diagnose it to determine what happened.
