2016 MINI Cooper

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 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, BMW X3 30i, BMW X4 30i, BMW 328i/330i, BMW 528i/530i, BMW 330e hybrid, BMW 530e hybrid, BMW Z4, Toyota Supra 2.0T, MINI Cooper S/JCW 3-door and 5-door, MINI Countryman, MINI Cooper S/JCW Convertible, etc. BMW is aware of this common failure. Thus far BMW has refused to issue a service campaign or recall for this problem which causes owners of these affected vehicles to be out of pocket thousands of dollars. If oil drips onto hot exhaust or into a wiring harness, it could easily cause a fire.

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 looks like it may have been going on a while. I purchased this car from a used dealership less than 3 months ago, and have already encountered so many unexpected issues. I really expected more from the Mini brand. Thanks.

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 this incident and the service center recommended completing a few panic stops to operate the ABS system. They could not explain how the wiper system can cause one circuit of the braking system to operate momentarily. A search of web forums for the F56 series MINI shows that this random locking of the RF & LR brakes with teh wipers in operation has happened to quite a few other owners of similar Mini Coopers. This problem creates a very significant safety risk.

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 inspection with the light on, and Mini dealer wants $2000 to replace radiator and sensor. Car currently has about 70,000 miles on it, but engine light as been on for approximately 15 months (emissions inspection is required every 24 months). I have a decent code reader, but it only provides "U019D generic code" which is why I took it to Mini dealer.

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 follow up with dealership to have lights & wiring harnesses on Driver side checked After research online regarding this year/make/model - I have found numerous other reports of other owners experiencing the same issues with burned wiring harnesses causing both front and rear light failure with no known causes.

MINI electrical systems have continued to develop over the past few years. As a result, the demand on the batteries has increased. Breakdowns due to an empty battery or problems in the vehicles electrical system can have various causes, most of which are not due to the battery itself. For this reason, a battery replacement will permanently eliminate the problem only in the rarest of cases. The energy diagnosis test module helps to localize these causes. This document covers important information for the dealer on how to handle “discharged battery” complaints. Without performing the energy diagnosis test plan, the root cause of a discharged battery cannot be identified. In order to properly repair the vehicle the first time, it is very important that the diagnostic test plan is performed to completion; with all results taken into consideration.
