“My 2012 Mini Cooper Countryman with 30,000 miles is requiring replacement of the thermostat and water pump - both of which were recalled and replaced on the 2011 Mini Cooper Countryman. There are not any parts in the united states currently to fix the car. We will be without our car for nearly 3 to 4 weeks while we wait for these parts and we have been told not to drive our car on the highway. The dealer said tough luck.”
NHTSA complaint #10871243, filed 2016-05, 29,952 miles“Driving on hwy and my car wouldn't accelerate no warning lights went off on the car so I pulled to the side of the road and had it towed to a shop that said that there was some sort of coolant leakage and a malfunction of thermostat so the engine over heated. They wanted to charge me 10,000 to fix it and the warranty that I bought for 2999.00 did not want to cover the cost. So the shop charged me 1500.00 to take the head apart and I had to tow it back home where it sits in my drive way.”
NHTSA complaint #11194680, filed 2019-04, 100,000 miles“I'm just noticing a coolant leak puddling up under from what I was told was the thermostat or it's housing or both.. My engine sounds like it's running with no oil. I go to check the dipstick and the oil at the very end of it seems almost impossible to accurately read, because it's not uniform in it's coating at the tip of it. Like if it was splashed on. Not sure if the auxiliary cooling system is even working anymore, which used to run for a minute or two after engine shut down. …”
NHTSA complaint #11076410, filed 2018-03, 92,800 miles“My Mini was stopped at a traffic light behind a toyota 4 runner when I was struck from the back by a careless driver in a midsize sedan who had failed to see the cars in front of her stopped at a red light. The damage done to both the car that struck mine from behind as well as the damage done to the 4 runner were minimal by comparison. The Mini incurred irreparable damage to the front end of the car. …”
NHTSA complaint #10468763, filed 2012-08, 400 miles“Engine light came on so I went in for a diagnostic. I live 2.5 hours from a Mini service center. The diagnostic at autozone just listed a bunch of misfires and nothing else. That explained the harsh sounding start and sputtering. As days have gone by, car will lose power in the middle of traffic, struggle up hills, fail to maintain speed limit, and struggle to start in the morning. All these events have occurred less than a month after being serviced at seattle Mini. …”
