2015 and 2016 Hard top Mini Coopers, Standard (F55) are prone to their environmental air catalyst sensor breaking, causing a check engine light and emissions issues. The remedy is replacing the entire radiator. This occurred on my vehicle at only 40,000 miles. MINI is aware of the issue, but only issued an extended warranty for "S" (or 4-cylinder) models, despite the 3-cylinder base model containing the same radiator sensors with the same defects. [XXX] This extended warranty should cover base models with the same parts. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The malfunction indicator lamp light is on (MIL) with the following fault code stored in the DME: Fault code Control module Fault code text 1B8302 DME LIN bus, communication (EAC sensor): missing Problem verified. Don't know if car will quit on the highway. Mini recall for exact problem and extended warranty to solve the problem only on the "S" model with the exact same engine.

The rear brake lights and rear signal indicator lights keep going in and out arbitrarily. It's dangerous because it will work fine and then just randomly stop working and then work again. People can't tell if I'm stopping or turning when this randomly occurs. This is currently not a recall on my Mini, however, I saw that it is a recall on other Minis and it seems mine is having the same issue so it's possible they all have similar or the same faulty wiring/electrical for the brake lights and signal indicator lights.

Oil filter housing failure. MINI issued a recall for this part in 2014 when the third generation MINI Cooper S/JCW first launched. Unfortunately they did not fix the part and now as time goes on, the issue is occurring with high frequency on every BMW/MINI and Toyota Supra with the BMW B46/B48 2.0L turbocharged engine. The plastic oil filter housings crack causing oil and coolant to leak. In my case oil poured down the front of the hot engine which could have caused a fire. BMW/MINI dealers charge nearly $2500 to repair this failure. The ODI should investigate this concern as it has been reported dozens of times on each model with this engine including the BMW X1 28i/M35, BMW X2 28i/M35,…

Drivetrain error occurred. I pulled codes and found P0015. I added oil, cleared code. The next day the drivetrain error popped back up. Pulled codes and found P0366. I took the vehicle to mechanic for diagnostics and to find the issue. They found faults: 130F11 and 120408. When replacing engine oil and filter, they found metal shavings in the oil; bearing material. They are recommending replacing the engine. Doing research, it appears this has been a common occurrence with these vehicles/engines. Is there a current recall on some of these engines, or a possibility for a discounted replacement due to the issues being widespread? The car has less than 74,000 miles, and the mechanic said it…

While driving straight on an Interstate highway at approximately 65 mph, the right front and left rear brakes momentarily locked up after the windshield wipers were turned on due to light rain starting to fall. This happened multiple times, only when the wipers were turned on. There were no warning lights illuminated in the instrument cluster or dash displays. This nearly caused a loss of vehicle control on several occasions and nearly caused an accident as well. The car has been routinely serviced to factory schedules including brake fluid time based changes. There appeared to be some occasional delay in the release of the brakes when starting from a stop. The brakes were serviced after…

Had recurring engine warning light which will only reset for one ignition cycle. Took to dealer to read code and result was "LIN bus communication fault for environmental air catalyst sensor". This is the same problem drivers of the Mini Cooper S model have reported and received an extended warranty from Mini of North America (15 year / 150000 mi) with replacement of sensor and radiator. However, talking with Mini of North America, the extended warranty does not apply to the base model 5-door Cooper because not enough complaints have been recorded. If more people report this issue, it could be covered just as the S-model is being covered. In the meantime, the car will not pass an emissions…

Rear passenger tail light casing/bucket had burnt connections. Replaced casing/bucket and bulb. Worked for short time, tail light failed a second time. Casing/bucket & bulb replaced, again worked for short time and then went out. Took vehicle to another mechanic after passenger side headlight failed. New mechanic checked casings/bucket - connections looked okay, however both wiring harnesses were severely burnt. Headlight harness was all bare wires. Mechanic unable to determine cause of the severe heat that would lead to both the headlight & taillight wiring harnesses becoming burnt so severely. Mechanic was concerned of the potential for this issue to cause vehicle fire. Suggested to…
