2016 BMW i3 Problems & Complaints

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.

Roof panel is deteriorating and loosing integrity. Outer laminate coat broke down in general sun conditions, and now underlying roof structure is breaking down as well. The dealer has not inspected the roof yet, but this is an issue widely discussed on community forums, and it’s breaking down on my vehicle now.

The roof is bubbling and peeling up. Water gets in it when it rains, then it bubbles greatly. BMW won’t fix it, repair shops don’t want to fix it because it’s an obscure roof. They recommend I take it to BMW which won’t fix it (roof replacement suggested). I just bought this car and drive it as normal, and the special carbon fiber roof is degrading too fast.

Roof peeling

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.

Vehicle experiences periodic loss of "power steering". Very difficult to steer or control. Steering does not re-center making control difficult. Steering is restored after shutting down the car for a few minutes. Dealership cannot find any faults or codes.

POWER STEERING FAILURE WHILE IN MOTION - OPERATING THE VEHICLE ON PUBLIC ROADWAY - MAKING IT DIFFICULT AND DANGEROUS TO NAVIGATE A TURN. NO WARNING LIGHTS APPEARED.

EVERY 3 TO 21 DAYS, MY STEERING PULLS HARD TO THE LEFT. THIS OCCURS ON FLAT ROADS ON DRY PAVEMENT. I HAVE TO PULL THE STEERING WHEEL HARD TO THE RIGHT TO KEEP THE VEHICLE GOING STRAIGHT AT CITY DRIVING SPEEDS (0-35 MPH). ON ONE OCCASION THIS OCCURRED WHILE ON THE FREEWAY DRIVING AT 70 MPH. TIRE PRESSURES ARE ALL WITHIN SPEC AND TIRES ARE IN GREAT SHAPE. AFTER STOPPING AND RESTARTING THE CAR, IT SOMETIMES WILL GO AWAY. IN LOOKING AT THE BMW RECALLS AND TECHNICAL NOTES, THEY HAVE NO SOLUTION TO THIS PROBLEM AND CALL IT A SOFTWARE ISSUE. THIS HAS HAPPENED TO ME AT LEAST 6 TIMES.

Faulty airbag warning

My bmw i3 has a faulty wiring harness or some other defect that is causing my car to turn off the airbag system. This is a chronic issue with bmw i3’s. Either the wiring harness is bad or the airbag becomes too stiff and the car deactivated the entire airbag system. Dangerous!

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."

STARTED THE CAR AFTER CHARGING IT OVERNIGHT AND "DRIVETRAIN: STOP CAREFULLY" AND "TRANSMISSION MALFUNCTION" APPEARED ON THE DASHBOARD. THE CAR HAS BEEN COMPLETELY FINE BEFORE THIS.

The contact owns a 2016 BMW I3. The contact stated that the driver restraint warning light was illuminated. The vehicle was diagnosed by the dealer, and the contact was informed that the front driver’s side air bag system was defective and needed to be replaced. The vehicle was not repaired. The manufacturer was contacted but offered no assistance. The failure mileage was 57,000.

Involved in a frontal collision and air bag did not deploy. Airbag could've prevented more serious injuries suffered. I contacted the service center at BMW Roseville and left a message for the service manager, no return call. The vehicle has been inspected by an insurance authorized collision center and is considered totaled. There were no warning there was a problem and didn't appear until the collision happened and it didn't deploy.

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.

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.

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.

The carbon fiber roof of my 2016 BMW i3 REx is really starting to bubble and wrinkle. After taking it to two shops any mitigation would cost hundreds of dollars to address. The roof is starting to peel and am worried about water getting to the car. BMW should have engineered these roofs differently. They should be responsible to cost associated with fixing them.

Battery degradation

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

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

I WAS PULLING INTO MY DRIVEWAY IN THE MORNING AT AROUND 9:15 AM PREPARING TO PARK BMW I3 ELECTRIC VEHICLE IN TO THE GARAGE. I HAD MY FOOT ON THE BRAKE AND WAS WAITING FOR THE GARAGE DOOR TO OPEN. THE VEHICLE WAS STATIONARY BUT NOTICE THAT BRAKE WAS NOT FUNCTIONING PROPERLY, MEANING THERE WAS NO FEELING OF VEHICLE WAS IN A LOCK POSITION DUE TO THE BRAKE BEING PRESSURED ON THE WHEEL. THEN ALL OF SUDDEN, THE VEHICLE WENT ACCELERATING OR "SUDDEN UNINTENDED ACCELERATION". THE VEHICLE WENT THROUGH THE GARAGE DOOR THAT WAS ONLY HALF WAY UP AND WAS STILL GOING UP. THEN, THE VEHICLE CONTINUED ITS UNINTENDED ACCELERATION CRASH IMPACT TO THE REFRIGERATOR THAT WAS AGAINST THE BACK SIDE OF THE GARAGE WALL. THE IMPACT OF THE VEHICLE TO THE REFRIGERATOR AND THE WALL TOOK OUT ENTIRE BACK SIDE OF THE GARAGE WALL OF ABOUT 20 FEET WIDE X 8 FEET TALL WALL AND THREW OFF REFRIGERATOR 50FT TO THE GROUND LEVEL. THE VEHICLE STOP FROM THE IMPACT AND ALMOST HALF OF ITS BODY LENGTH WAS CANTILEVERING OFF THE EDGE OF THE BACK SIDE OF WALL. MY HOUSE IS BUILT ON ABOUT 35 DEGREE SLOPE AND THE VEHICLE WAS CANTILEVERED ABOUT 45 FEET FROM THE GROUND. THE POLICE AND FIRE DEPARTMENT WAS CALLED AND THEY WERE ABLE TO SAFELY BRING THE VEHICLE OFF THE EDGE AND THE VEHICLE WAS TOW TO THE LOCAL BMW DEALER WHERE I HAD IT LEASED. I MADE A REQUESTED TO THE LOCAL DEALER MANAGER IN PERSON NOT TO TEMPER WITH THE VEHICLE UNTIL ALL PARTIES THAT MAY HAVE INTEREST IN THIS CASE HAVE MADE THEIR INPUT ON IT. I'VE CALLED IN TO THE BMW NORTH AMERICA AND INFORMED THIS INCIDENT. I'VE REPORTED THIS INCIDENT TO MY HOME AND AUTO INSURANCE COMPANY. PLEASE REVIEW THIS CASE BECAUSE THE CONDITION THAT I AM REPORTING "SUDDEN UNINTENDED ACCELERATION" DID HAPPEN AND IT WAS SUPER FAST! THE TOTAL DISTANCE THE VEHICLE TRAVELED FROM THE STATION POSITION TO IMPACT/STOP WAS ABOUT 50 FEET MAXIMUM, STANDARD GARAGE LENGTH PLUS ABOUT 10 FEET.
