Front passenger side motor mount failed pretty terribly, the rubber completely slipped off the engine side mount leaving a severe engine vibration. The mount is very under engineered. Ours failed at 27,0000 miles.

Lower Engine Support and Passenger Engine Mount damaged as per routine inspection by dealer in Feb2025. Never diagnosed before. Repair done by independent service center in Feb2025 and I have receipt of approximately 1K. Also, since 22feb2025, I am not able to add fuel to the tank because the pump stops constantly and causes spill of fuel. This can cause fire. Never happened before. Tried at least 4 different gas station and same result. Dealer charges over $200 to perform inspection/diagnostics. Not done yet. Repairs to fuel tank are in the thousands. No warning in the car dashboard for none of the issues. Car with less than 80k miles.
Car stalls while driving and will not start again. No codes thrown. Found relay K96 on Junction Box Electronics module to have cracked through-hole solder joints resulting in bad continuity. Relay K96 supplies power to the low pressure fuel pump in the tank, thus with bad continuity, the pump gets no power. Relay K96 P/N is NEC Philippines P/N EP2F-B3G1ST. This issue has happened to many other people with the same car that I know. I suspect heat cycles over time stressed and fatigued the solder joints, causing the...

joint to crack. Overall the circuit board layout needs a heat sink for the relay to alleviate the heat produced from operation. I am IPC certified and work with aircraft engine electronics regularly and have seen similar issues.
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. [[redacted]] I've also included links to various forums and news articles about this issue.

engine failure and I don't know what else to do but I saw this recall and I thought I would give you guys a shout and tell you what's wrong and the only thing I replace so far was a new fuel pump and unfortunately that was not the issue my car was still not run or start and now I noticed there is a broken seal in the air intake that looks like it needs to be replaced
Freeze plug randomly popped out while driving causing vehicle to stall in the middle of traffic almost causing a major accident and or death. Research indicates there has been numerous complaints by Mini Cooper owners experiencing the same issue of a premature unexplained failure with no action taken from Mini to mitigate this safety issue. I'm lucky to be alive.

Nothing has failed yet, however, the oil stick is completely illegible. On a car that fails to have an electronic dipstick and likes to burn oil, as well as has a very small oil capacity (Around 5 liters or less) this design is going to cause the engine to run out of oil without the driver knowing. It is a seriously bad design, especially combined with BMW recommending a 10,000 mile oil change, the car will burn off all the oil it has and operator will have no idea due to the faulty design of the dipstick. I...

generally like BMWS engineering and designs, but this one is just atrocious and I have no idea how it got approved. Running a car out of oil usually causes the engine seize unless you shut it off at the right time, which, most people will not do. Imagine if your engine seizes on the highway? No it hasn't been inspected, I can send pictures of it, if you want? Or a video? I have not had this problem yet (knock on wood) but I have read the only warning sign, is the sound of an engine without oil and the oil pressure light comes on (which at that point you have maybe 3s to pull over and shut off the engine before it toasts the engine) I have also read about the engines consuming the entire oil capacity if you follow the BMW recommended schedule. It all just seems like a huge oversight for a company that usually has few issues.
Repeated experiences of sudden engine operational failure and reduced and/or complete loss of power while driving. The engine malfunction indicator lamp comes on. Car stalls and stops in traffic on the highway and on streets blocking traffic. Will not start again until powered off for periods between 5-15 minutes if at all. -First experienced the issue February 2020 and have intermittently experienced the same issue ever since. -Occurs when driving at a variety of speeds and a variety of fuel levels. -If...
