My 2021 MINI Cooper Countryman S model with John Cooper Works had to have a part replaced, a valve part, that allows the fuel tank to release air from the fuel tank. I had a message or symbol on the dash with an alert that would come on but then go away. I took it to the Sewell BMW MINI dealership in Plano, TX, on Spring Creek Parkway, and they diagnosed it and fixed it. The buildup of the air in the gas tank could have caused an explosion. Luckily, it was covered under my OEM warranty.

The vehicle brakes during turns in the road when it is inappropriate. Has led to braking almost to a stop on the highway in one incident and could possibly cause a rear end collision. It has done this around 30 times in the past year of owning the vehicle and has begun to cause anxiety on the road due to not knowing when it will activate. It also has not warned during near front end collisions when it should have. The software is faulty and I have brought it to the Mini of Dallas’ attention as well as the Mini of Arlington and the Mini/BMW N. America executive customer relations team which set up an appointment once for it to be inspected but then they said they couldn’t ‘recreate the road conditions’ and thus couldn’t do anything for me. Mini of Dallas said the same thing as well. No resolution even when having talked with the highest customer sales reps. Not really sure how to get this issue fixed. The mini of Dallas said it was the ‘computer just seeing ghosts in the screen’ and even though they recalibrated it or turned the sensitivity down it continues to do this random braking in bends of roads with no one on the road, oncoming traffic on the opposite side of the road, and other situations.
