The roof of the BMW started delaminating a few years back, and it is compromising the structural integrity of this vehicle. In an attempt to fix the roof, epoxy was applied after it was smoothed down and the roof looked aesthetically pleasing for about a year, until it started delaminating rapidly in the same spots. Now, the roof liner is starting to collapse, telling me that moisture is getting into the vehicle, further damaging the roof.

BMW Service Bulletin SI B22 04 15 to replace motor mount bolts and other components due to failure in 2016 was done on my vehicle in 2016. BMW has replaced all motor mounts in 2014 and 2015 i3's in Europe. The motor mounts were redesigned for 2016 and newer models. From online forums I see that many of the 2014 and 2015 North American i3 motor mounts continue to fail as they have on my BMW i3. I am reporting this failure in order for NHTSA to review this vehicle for a recall on motor mounts for all 2014 and 2015 USA BMW i3's.

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…

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. Iâm afraid that a larger chunk may hit somebodyâs 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…
