NHTSA Complaint #11626962 — 2016 MINI COOPER S

There have been thousands upon thousands of failures of the oil cooler/oil filter housing on all BMW/MINI B46/B48 2.0T engines. This problem dates back to 2014 when BMW issued a stop sale order and recall on the 2014 MINI Cooper with both the 1.5L I3 (B38) and 2.0L I4 (B48) engines. Since 2014, the engine has been installed in over two million vehicles sold in the United States under the BMW, MINI, Karma, and Toyota brands. There is a defect with the oil cooler/oil filter housing that leads to coolant and oil leaks due to the plastic housing failing after being heat cycled a certain number of times. It has gotten so bad that numerous aftermarket metal replacement parts exist to try and prevent this issue from recurring. Due to the placement of the part on the engine, the repair costs up to $3000. Failures are occurring on vehicles with as little as 30,000 miles, but vast majority between 50,000-80,000 miles. Due to the loss of both oil and coolant, a fire risk exists. Coolant can come in contact with electrical components and cause a short, while the oil can begin to drip onto hot engine or exhaust parts. This is a dangerous hazard that should be recalled. BMW should refit affected engines with a more durable component. Below I have included a link to the original NHTSA stop-sale from 2014.
