2016 BMW I3 Problems

The roof has bubbled and peeled away leaving an exposed permeable roof, meaning if it rains, water will get into the car because of the roof material being not safe, not strong, peeling away. Just terrible! Looking online, so many people with i3s ha e all had the same issue!

Translucent protection coat on roof delaminated; pieces blown into air. Bare roof and some coat pieces available for inspection upon request (no inspection yet). Other BMW i3 owners have reported same issue. No prior indication of problem on vehicle itself.

The contact owns a 2016 BMW I3. The contact stated while driving at various speeds, the steering wheel became difficult to maneuver. Additionally, the contact stated that after making a turn, the steering wheel failed to properly return to center. No warning lights were illuminated. The vehicle was taken to an independent mechanic however, the cause of the failure could not be duplicated. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 88,000.

Previously reported a steering incident no. 11438343. Dealer indidicated that there was a "bug in the software" and that the car would be entitled to a one time fix under extended warranty. Dealership worked on the issue and completed the warranty repair on 11/28/2021 and I picked up the vehicle. Upon starting the car, the steering felt "different". I turned right to exit the dealership and tried to straighten the car but the steering turned full left and I crossed into the opposite lane of traffic. I stopped, turned the wheel to center, let it go and it turned full left on its own. I shut the car off, restarted and steering was normal. Drove back to the dealership for them to complete the repair. Dealership reported that this has occurred once for them but they cannot get it to repeat so they are going to keep the car for a few days. I am concerned that they will consider this an out of warranty repair because they were clear that they would offer a "one time fix" for the known issue.

Driver airbag warning light illuminated. Vehicle was diagnosed at BMW of Sherman Oaks (RO# 176741) and confirmed as a faulty driver airbag module - part# 32-30-6-870-366. BMW technician found fault code 930904: Driver's airbag interval stage 1, resistance too high stored. BMW NA declined goodwill repair assistance despite the failure occurring within 20 days of warranty expiration. This is a safety-critical federally mandated system. Multiple BMW i3 owners in online communities report the same issue and reference TSB SI B65 18 16 as a known defect related to a cable being too short. I believe this may be a widespread defect affecting 2014-2018 BMW i3 vehicles that warrants investigation.

Faulty airbag warning

While driving my 2016 BMW i3 with Range Extender, the vehicle experiences sudden and complete loss of propulsion at very low state of charge (0–1%). The car abruptly loses motive power, forcing me to pull over, sometimes while in traffic. After sitting for several minutes, limited power may return, but the vehicle often shuts down again, and in some cases the Range Extender engine does not engage at all. This has occurred repeatedly and creates a serious risk of being stranded or hit while merging or driving on public roads. BMW has inspected the vehicle twice (07 Nov 2025 and 13 Jan 2026) and confirmed the loss of propulsion and need to pull over but classified the behavior as “normal” without performing high-voltage battery diagnostics. The failure appears consistent with high-voltage battery voltage collapse under load, causing the battery management system to shut down the drivetrain. This is not normal power limiting — it is a sudden drivetrain shutdown that occurs without warning and poses a significant safety hazard.

Loses power "without warning"; actually, when the REX turns on it automatically mentions that power "could be" lost when the REX turns on. However, that is very understated. In fact, there is nowhere in the owner's manual that raises this issue; doesn't even mention that there could or would be a "warning" if battery is low and REX is being used. Bottom line: The REX cannot keep up with driving. Please refer to: https://www.youtube.com/watch?v=hmn58reGv8k The above is identical to my experience. Especially VERY DANGEROUS when on the interstate highway. I was looking for an exit so that the battery might recharge a bit because I could only go 25-35 mph. Seems like the REX is warming up and not outputting standard power, as expected... It might be that the problem is that the computer is not calculating the correct state of charge and therefore not giving the REX enough time to complete its warm-up cycle.? Or it should kick in earlier than single digit battery strength left. I started recording at 9% SoC and I was expecting this power loss. I found a safe(r) road to do this on with minimal traffic. Fast Forward to 2:59 to see the power-loss happen. The first time this happened I was on the highway, that was not fun. To quote another driver with the same issue (see YouTube earlier), "Power-loss due to low charge should be gradual and with a warning, not this sudden. This makes for a dangerous situation if I'm on the highway or hill. I know that enabling 'hold state of charge' before 7.5% is a 'manual workaround' but that is NOT a fix. HSOC is not even an option on the REX in the USA - you have to unhide the menu via a coding change."

THE "STOP AND GO" CRUISE CONTROL HAS DISENGAGED OVER 100 TIMES AND HAS SLAMMED ON THE BRAKES FOR NO REASON 5 TIMES. I HAVE ALMOST BEEN REAR ENDED TWICE ON THE HIGHWAY. THIS IS NOT SAFE. I HAVE SHOWN BMW OVER 50 PHOTOS AND 3 VIDEOS OF THIS AND THEY FIND EVERY EXCUSE IN THE BOOK. I AM SCARED FOR MY LIFE WHEN USING THIS CRUISE CONTROL. BMW ALSO REFUSES TO TAKE THE CAR BACK.

WHEN ELECTRIC RANGE IS OUT, THE ENGINE KICKS IN AND SPEED IMMEDIATELY DROP TO 50+MPH ON THE FREEWAY CLIMBING UP A HILL THE FIRST DAY I BOUGHT THE CAR WHICH SCARES ME AND I HAVE TO STAY ON THE LEFT LANE AND QUICKLY EXIT. I JUST READ THE LAWSUIT WHICH IS EXACTLY WHAT HAPPEN TO ME TOO.

The contact owns a 2016 BMW I3. The contact stated that while driving at an undisclosed speed, the check engine and the air bag warning lights illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the fuel filler had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for further assistance. The approximate failure mileage was 40,000.

TL* THE CONTACT OWNS A 2016 BMW I3. WHILE DRIVING 35 MPH, BOTH WINDOWS ROLLED DOWN, THE POWER STEERING SEIZED, AND THE ENGINE SHUT OFF. THE CONTACT RESTARTED THE VEHICLE AND PULLED INTO A FUEL STATION. THE FAILURE RECURRED AND THE VEHICLE WAS TAKEN TO BMW NORTHWEST (4011 20TH ST E, TACOMA, WA 98424, (253) 922-8700); HOWEVER, THEY COULD NOT REPLICATE THE FAILURES. THE CONTACT WAS PROVIDED A LOANER VEHICLE. AFTER ANOTHER TWO WEEKS, A REGIONAL SERVICE MANAGER FROM THE MANUFACTURER DIAGNOSED THE FAILURES AND STATED THAT A SOFTWARE REPAIR WAS NEEDED, BUT IT WOULD NOT BE AVAILABLE FOR POSSIBLY ANOTHER TWO MONTHS. THE VEHICLE WAS NOT REPAIRED AND WAS CURRENTLY STILL AT THE DEALER. THE FAILURE MILEAGE WAS 29,000. THE VIN WAS UNKNOWN. *TR*JB

ON A FREEWAY DRIVING AROUND 65MPH FRONT CAR CAME TO SUDDEN STOP SO APPLIED BRAKES AT FULL STRENGTH BUT CAR CONTINUED AT THE SAME SPEED FOR FEW SECONDS AND THEN BRAKES TOOK EFFECT BUT IT WAS TOO LATE BY THEN. THERE SEEMS TO BE SOME SORT OF LAG BETWEEN WHEN BRAKE PEDAL PRESSED AND ACTUALLY BREAKS GET APPLIED TO SLOW DOWN VEHICLE. ALL 4 TIRES ARE NEW AND SERVICING DONE 4 MONTHS BACK. *TR
