2014 BMW I3 — Problems, Recalls & Safety Data

back in march 2025 my 2014 BMW i3 REX gave out a "Drivetrain Malfunction" error. The car's propulsion died while driving. I was driving in the street on the way home from picking up my chidren from school when the power completely shut off while driving. I had a full battery charge and also had about 44 miles worth of gas to use. I pull over to the side of the road, turn the car off and tried to turn it back on but it wouldnt move. i was about 1 mile from home and was able to get the car towed home using AAA. The error code disappeared the next day and i kept driving the car it felt as if it the problem went away. Fast forward Augist 1 2025, the car once again shut off while in the middle of the street driving. I could not get it back on and once again had to get it towed. Once home it started back up like nothing wihtin a few hours. A week later on August 8 it did it again but this time i was driving on the freeway. I was soo afraid for my life because the car started to slow down as if it was runing out of gas and barely made it to get onto the side of the road away from traffic. Once again the car got towed home i was 4 miles away from home. These occurences continue to happen more frequently now. With each time the car started the error message reappeared and the propulsion died. This is gettting out of hand and becoming dangerous for me.

The carbon fiber roof is delaminating and a portion of it came off and hit the front windshield of another car, causing them to partially lose control of their vehicle almost causing an accident. This is a known issue BMW has not taken an action to resolve it. I’m afraid that a larger chunk may hit somebody’s car and cause a severe accident.

A large portion of the car's hood (carbon laminate?) has ripped off and is surely to continue to tear and fly off while driving.

When the vehicle depletes it's battery and switches over to the range extender or the gas engine, the car will suddenly shut off and a drivetrain error appears. This seems to only happen when the car is traveling over 55 mph. This has happened on repeated occasions. If you then leave the car sit for several minutes and then turn it back on, it is driveable as long as it is driven under 55 mph. Since this only happens at higher speeds, it's been extremely dangerous because other cars are also traveling at high speeds and this has happened once on a freeway where the speed limit was 70 mph. If there's no shoulder to guide the car onto when this happens, the car would be disabled on the road because it will not drive again right away. I've taken it in to fix and the mechanic said it was a software update that was needed. However, the problem happened again a few months later. There was no warning before this happened both times it occurred.

AC Compressor for the car battery system failed. There was a check engine light that was on steady, but not flashing. The electric range in the car reduced by 20 to 30% as a result of this fault. It was brought into the BMW dealership for inspection and they determined that was a short in the AC compressor and that the whole AC compressor system would need to be replaced; compressor, lines and radiatorx2 (battery radiator also needed). This was because this typical failure causes metal filings to enter the cooling system and it's not recommended to flush it out. There were no prior warnings or noise leading up to the problem. I'm concerned that there is a high risk that further driving the vehicle or charging it could cause a battery failure and cause it to catch on fire since there is no cooling. Normally a flashing engine light means to stop driving immediately, but there was no flashing light only a steady light. The BWM system check menu reported no issue with the car! The repair bill for this is about $8,400 and is rediculous. This seems to be a common problem when you start searching for it. Seems to also happen to the BMW i8 which shares the same compressor. Note that there are several revisions to the ac compressor part number which seems to suggest that they had to keep changing the part as production went on but did not notify affected cars that they could have a serious problem. This shouldn't be happening at 77k miles.
