2017 BMW I3 Problems

The carbon fiber roof panel is starting to delaminate and I am concerned that pieces could fly off and cause an accident.

On May 30, 2026, I was driving on the NJ Turnpike with high winds and I heard loud sounds like hard rain on the roof of my BMW i3. I saw sheets flying off the roof. When I parked the car, the clear coat covering the roof had delaminated, exposing the carbon fiber. The BMW collision shop told me that the roof panel has to be replaced and it is costly.

I had just turned on the car a few minutes prior to the incident and I was approaching an intersection to turn left onto a 2-lane highway. As I made the left turn, the steering felt wrong like the car was over then under steering. I was able to straighten out, and I felt like the power steering had failed. A quarter mile down the road, I turned left into a gas station, and I could feel the heaviness of the steering. It felt exactly like if the power steering was deactivated. I came to a stop, turn off fans, rolled the window down, and turned the steering wheel to see if there were any odd noises. There weren't. There were no error lamps or messages displayed. I turned off the car for a minute then back on again. The steering felt fine from then on. It felt unsafe because of the sudden loss of expected steering control. I have not yet taken the car to the dealer for this issue, but it was at the dealership two weeks ago for an oil change and inspection.

ROADS WERE CLEAR BUT EDGES SLUSHY. TEMP WAS 27 DEGREES.DROVE 2 MILES AT 40ISH MPH TO STARBUCKS, GOT COFFEE. NORMAL REAR WHEEL DRIVE TRACTION ISSUES WHEN CHANGING LANES, ETC. I WAS DRIVING CAREFULLY AND ABOUT 5 MPH UNDER WHAT EVERYONE ELSE WAS DOING. ABOUT A MILE AWAY FROM THE COFFEE DRIVE THROUGH, I CHANGED LANES (RIGHT TO LEFT) OVER A PILE OF SLUSH...NORMAL MILD TRACTION ISSUES. WAS IN THE LEFT LANE AND HAD "RECOVERED" WHEN SUDDENLY MORE YELLOW TRACTION WARNING LIGHTS CAME ON (ONE ON DRIVERS CONTROL PANEL, ONE ON THE INFO PANEL)...READING IT LATER, IT SAID TO DRIVE GENTLY, THE TRACTION CONTROL SYSTEM WAS RECALIBRATING. I AM A VERY GOOD DRIVER...I LOST COMPLETE CONTROL. I WAS STEERING INTO THE SKID, BUT IT DIDN'T FEEL LIKE A NORMAL SKID. IT DIDN'T SLOW (I KNOW NOT TO BRAKE - AND THERE WASN'T ANY TRAFFIC TO WORRY ABOUT). COMPLETELY INTO THE RIGHT BREAKDOWN LANE, RECOVERED SOMEWHAT, INTO THE LEFT LANE UNTIL I FINALLY GENTLY HIT THE CURB AT ABOUT 10 MPH. I WAS GOING ABOUT 35 MPH WHEN THE NIGHTMARE STARTED. EVEN AFTER GAINING SOME MODICUM OF CONTROL, I COULDN'T GO MORE THAN ABOUT 20 MPH WITHOUT COMPLETELY LOSING ANY KIND OF TRACTION CONTROL. PULLED OVER, TURNED THE CAR OFF/ON...NO CHANGE. PULLED OVER, RESET THE CAR BY WALKING 15 YDS AWAY WITH THE KEYS FOR 15 MINUTES, I COULD PULL OUT AND DRIVE NORMALLY FOR 100 YDS, THEN THE "RECALIBRATING" NOTIFICATION WOULD COME ON AND I WOULD LOSE CONTROL. I WAS ON 4 LANE HIGHWAY WITH MEDIAN. EVEN AFTER WAITING 2 HOURS FOR A TOW, THE PAVEMENT WAS DRY AND I HAD NO CONTROL.

There was an electrical fault in the door handle, specifically for the comfort access function circuit inside the handle itself. There was smoke and extreme heat. Luckily no fire started, before the battery was disconnected. Our understanding is, this is a known problem with the circuit board having corrosion and creating a short, but no recall exists.

What component or system failed or malfunctioned, and is it available for inspection upon request? There seems to be a series of faulty electrical/wiring issues happening with our 2017 BMW i3, most notably including the passenger seat/airbag registering system and control panel/console lighting. Yes, it is available for inspection upon request. How was your safety or the safety of others put at risk? We are unsure how this issue impacts the passenger airbag system. BMW was also not able to tell us whether the passenger airbag is impacted by the electrical issue. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? A local BMW dealership inspected the issue. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The failure lights and error message were the first indication of a problem. This first happened in March 2021 when we starting receiving an error for the passenger seat sensor: “Passenger Restraint System: Malfunction. Continue wearing safety belt. Consult the nearest service center.” We took it to the dealership asking for coverage on the item and they said it would be $2,000-$3,000 out of pocket to fix. I filed a complaint with [email protected] and BMW and have not heard back from either. Over the past 6 months, the console lighting has now started malfunctioning as well. Lights will flicker in and out while they are active. For example, the heated seat may be on level 3, but only the two end lights are illuminated. Sometimes the heated seat will be active with no lights illuminated at all. Sometimes the heated seats will turn on with no way to shut it off. The evolving electrical issues concern me considering this is an electric vehicle.

The vehicle has just over 35000 miles of light normal use as a second family vehicle. It developed a loud grinding noise from the etransmission that quickly progressed to a vibration. It was taken to BMW Seattle where it was diagnosed as a known issue of the main transmission bearings disintegrating due to the effect of the permanent magnet motors on the metal roller bearings. The bearings were quietly modified by BMW for the 2019 model year due to this in an effort to mitigate the problem and subsequently BMW abandoned the permanent magnet motor technology due to this . This information was from the various BMW service advisors. The repair is quoted as $7400 to replece the entire e transmission to the new design. If unrepaired there is a " significant risk the transmission will jam at highway speed causing a loss of control due to rear wheel lockup". Calls to BMW NA about this issue were replied with "BMW is unwilling to assist the customer with this issue." It is unconscionable that a vehicle with 35000m and a 4 year 50 000m warranty would have its transmission disintegrate with the potential of a catastrophic accident under light use due to a known manufacturer defect and BMW would not even attempt to assist their customers when they have the rectification available.

The car turned off while driving and presented a "drivetrain" error message. The car lost power but I was able to safely steer to the side of the road. Car was taken to BMW dealer and a diagnostic test was performed. Was informed that the EME (Electric Motor Electronics) Module was bad and would need to be replaced. The car is 5 years old and has 31,700 miles and has never been in an accident. The estimate to replace the EME was $7,000

WHEN THE VEHICLE IS IN ECO PRO PLUS MOOD. WHILE SPEED IS ABOVE 56MPH THE VEHICLE WILL SOMTIMES AUTOMATICALLY BREAK TO 56 MPH. WHEN IN CRUISE CONTROL THIS SEEMS TO HAPPENED WHEN CRUISE CONTROL IS DISENGAGED EVERY TIME. I FEEL THIS IS A SAFTY CONCERN ESPECIALLY WHEN I TRY TO ACCELERATE BUT THE CAR WILL IGNORE MY INPUT AND CONTINUE TO DEACCELERATE TO THE ECONOMY PRO PLUS 56 SPEED.

TL* THE CONTACT OWNED A 2017 BMW I3. THE CONTACT STATED THAT WHILE AT A COMPLETE STOP, HIS VEHICLE ACCELERATED INDEPENDENTLY INTO ON COMING TRAFFIC WITHOUT WARNING. AS THE CONTACT STRUGGLED TO REGAIN CONTROL OF THE VEHICLE, HE STEERED THE VEHICLE INTO A WOODED AREA WHERE HE HIT A TRASH DUMPSTER. THE AIR BAGS DID NOT DEPLOY UPON IMPACT. THE CONTACT SUFFERED A HEADACHE AND INJURIES TO HIS BACK AND NECK AREA. THE CONTACT DID NOT RECEIVE MEDICAL ATTENTION AT THE SCENE. THE POLICE WAS CALLED; HOWEVER, THE CONTACT NEVER RECEIVED A POLICE REPORT. THE VEHICLE WAS TOWED TO BMW OF BUENA PARK (6750 AUTO CENTER DR, BUENA PARK, CA 90621) TO BE INVESTIGATED. THE CONTACT WAS UNABLE TO STATE WHAT THE INVESTIGATION FOUND; HOWEVER, THE INVESTIGATION DID DEEM THE VEHICLE A TOTAL LOSS. THE MANUFACTURER WAS INFORMED OF THE FAILURE AND AGREED TO PAY FOR A RENTAL VEHICLE. THE MANUFACTURER OFFERED NO FURTHER ASSISTANCE. THE FAILURE MILEAGE WAS APPROXIMATELY 26,680. *JS

Summary On September 30, 2025, the passenger in a 2017 BMW i3 REX was involved in a severe frontal collision with a Gas Company Utility Vehicle. The impact struck the driver’s side extending toward the passenger side, causing the vehicle to spin violently and nearly flip. The passenger reports seatbelt failure with excessive slack, leading to partial ejection from the seat, mid-thigh restraint, and collision with the steering wheel. The head lodged under the steering column, resulting in loss of consciousness and a severe traumatic brain injury (TBI) with ongoing neurological issues. Only the driver’s curtain and seat airbags deployed; the steering wheel and passenger frontal airbags did not. Seatbelt Failure Analysis Seatbelts in modern vehicles like the BMW i3 include retractors and pretensioners designed to lock and tighten upon impact detection via accelerometers. Excessive slack, as described, suggests a malfunction in the pretensioner system, which failed to eliminate belt looseness during the high-G force event. This allowed forward momentum to propel the occupant, exacerbating injuries. Common issues in BMW i3 models include seatbelt twisting and retractor malfunctions, as reported in owner forums and repair services. Pretensioner failures can stem from sensor errors, mechanical wear, or manufacturing defects. In this crash’s severity, proper function should have secured the occupant, preventing ejection and secondary impacts. Airbag Failure Analysis The BMW employs a supplemental restraint system (SRS) with frontal, side, curtain, and seat airbags, triggered by crash sensors evaluating impact direction and force. Non-deployment of the passenger frontal and steering wheel airbags in a near-head-on collision indicates potential system failure. Possible causes include faulty occupant classification system (OCS) mats that misdetect presence/weight, leading to deactivation; sensor malfunctions; or wiring issues. A 2017 NHTSA recall (17V-720).

Message saying driver restraint failure, air bags may not deploy properly. Random event, has been an issue with bmw i3 models.

A DAY AFTER THE RECOMMENDED SERVICE. WHILE DRIVING ON I 95 WITH RANGE EXTENDER, NOTICED THE DRIVE TRAIN MALFUNCTION ALERT WITH RAPID DECELERATION NEEDING TO PULL TO THE RIGHT SHOULDER QUICKLY. BMW ASSIST TOOK THE CAR TO THE NEAREST BMW DEALER, WHO SAID IT WAS LACK OF ELECTRIC CHARGE, PLUGGED THE CAR IN CHARGER AND GAVE IT TO ME TO HEAD BACK HOME TOWN. FEW DAYS LATER THE PROBLEM AGAIN RECURRED. NOW THE CAR IS AT THE DEALER IN HOME TOWN.

WHILE DRIVING ON THE FREEWAY'S HOV LANE (FULLY CHARGED, NOT ON THE EXTENDED RANGE), THE CAR GAVE "DRIVETRAIN MALFUNCTION" AND THE PROPULSION DIED SHORTLY AFTER.

The contact owns a 2017 BMW I3. The contact stated that while driving at an undisclosed speed, the windshield wiper fluid failed to function as intended. The contact's husband checked the windshield wiper reservoir; the hose had rodent teeth marks, and part of the tubing was missing. The vehicle was taken to the dealer, where the vehicle was repaired. The contact stated that on a separate occasion, the failure persisted. The contact's husband checked the reservoir and found that rodents had eaten the tubing again and had built a nest inside the vehicle. The vehicle was not diagnosed or repaired. The contact's husband repaired the vehicle. Upon further investigation, the contact found out that the manufacturer had added soy to all the plastic tubing in the vehicle, which was an attractant to the rodents. The failure persisted. The vehicle remained at the dealer pending the repair. The manufacturer was not made aware of the issue. The failure mileage was approximately 32,000.

THE FRONT WINDSHIELD IS IRREGULAR, WHICH CAUSES EXTREME DISTORTION OF THE VIEW. DRIVING IS DANGEROUS AS THE DISTORTION CAUSES DIZZINESS. THE IMAGES I SEE ARE SEVERELY DISTORTED WITH THE CAR STOPPED OR IN MOTION BUT IT GETS WORSE WHEN MY CAR AND THE CAR AHEAD ARE IN MOTION AS BOTH THE ROAD AND THE CAR AHEAD ARE SHOWING VARIOUS DISTORTIONS AS THEY MOVE. THE BRAIN CAPTURES THESE DISTORTIONS WHICH ARE SLIGHTLY DIFFERENT FOR EACH EYE AND THAT IS CAUSING THE DIZZINESS AND DANGER. THE CAR HAS JUST 400 MILES AND DRIVING UNDER THESE CONDITIONS IS HAZARDOUS. THE DEALER STATES THERE IS NOTHING WRONG WITH THE CAR. I LEFT THE CAR WITH THEM FOR ONE WEEK AND ACCORDING TO THE MILES IN/OUT, THEY DID NOT DRIVE THE CAR TO PERFORM A REAL INSPECTION OF MY COMPLAINS. THE DEALER WAS BRAMAN BMW, THE SERVICE PERSON WAS MARUF DIB MUCHALLAH AND HIS EMAIL IS [email protected], 305-203-6184. I AM AFRAID THIS MAY BE A DEFECTIVE BATCH THAT MAY BE PUTTING OTHER LIVES AT RISK AS WELL. I PURCHASED THE VEHICLE 3/5/2017 AND ON ALL THE DAYS (NOT MANY) THAT I DROVE IT, I EXPERIENCED SEVERE DIZZINESS.

THERE IS RAPID ACCELERATION WHILE TAKING FOOT OFF ACCELERATOR WHEN THE CAR IS IN MOTION GOING UP HILL. ANTILOCK BRAKES SLOW TO ENGAGE ON STEEP DECLINES AND APPROACHING A STOP SIGN. THERE IS TOO MUCH POWER TO THE REAR WHEEL, THE CAR SKIDS ON PAINTED SURFACES SUCH AS CROSS WALKS AND PAINTED YIELD SIGNS ON ROAD SURFACES WHEN ACCELERATING FROM A FULL STOP. THE WHEELS SPIN ON CROSSWALK PAINT. THE CAR HAS A BUILT IN GYROSCOPE AND PULLS TO THE LEFT WHEN STARTING FROM A PARKED POSITION AFTER PARKED FOR SEVERAL DAYS ON A HILL. THE PULLING CONTINUES FOR SEVERAL BLOCKS. THE CAR NEEDS A NEW SET OF TIRES AND ONLY HAS 10,000 MILES. THE CAR HAS BEEN INSPECTED TWICE BY BMW TECHNICIANS AT PETER PAN BMW IN BURLINGAME. WE WERE TOLD THE SURFACES SIMILAR TO THOSE FOUND IN SAN FRANCISCO WERE REPLICATED IN BURLINGAME AND THERE WAS NO PROBLEM WITH THE CAR. THE PROBLEMS STILL PERSISTS.

We have experienced a mechanical issue with the harness system. Specifically, the straps become extremely difficult to tighten or loosen over time. To adjust them, I have to pull with the full force of a 200lb adult, to the point where it literally shakes the car. Despite following all manufacturer instructions—including cleaning the adjuster area and checking for twisted straps—the problem persists. Evenflo recently closed our support case (#00609796) and sent a replacement seat, which suggests an acknowledgement of the problem. Before I return the impacted seat (as Evenflo Requested), I wanted to reach out here promptly. I am particularly concerned because this appears to be a systemic issue. I would like to include this Reddit thread of other parents experiencing the same harness strap issue: Reddit Discussion: Evenflo 360 straps hard to tighten and loosen https://www.reddit.com/r/CPST/comments/1pzus73/evenflo_360straps_hard_to_tighten_and_loosen/ A cursory look at this Reddit thread shows at least 10 separate people with this same issue. I have documented interactions with Evenflo Parentlink via email and have photos attached and video link here. https://drive.google.com/file/d/1Ogbu8VN-45InQIfCxfnLJaeGgvzcRcRg/view?usp=sharing Thanks Matt Figler (914) 715-8954

RIGHT REAR SUSPENSION CONTROL ARM SNAPPED (STEEL FRACTURED) UNEXPECTEDLY. THERE WAS NO ACCIDENT OR ROAD DAMAGE TO THE VEHICLE. THE VEHICLE WAS STOPPED AT A STOP SIGN, AND THE FRACTURE OCCURRED AFTER GENTLY ACCELERATING FROM A STOP. THE VEHICLE IMMEDIATELY BECAME DIFFICULT TO STEER, AND ALIGNMENT WENT WAY OUT

The UTQG ratings on these tires are fraudulent. The ratings give an A grade for temperature over 115 but these tires wear out rapidly in Arizona. They also rate the tire wear at 400 which is also fraudulent. On my own vehicle I get less than 11,000 miles on each set and I’ve seen online complaints as low as 6,000 miles to failure. This is consumer fraud and tires that wear down this rapidly are a safety hazard.

While driving on the freeway, the vehicle's electric motor suddenly died. Because this is an electric vehicle, the car came to a sudden and abrupt stop, with all the wheels locking up. The car would not shift into drive or neutral or reverse. It effectively died, with the only power coming from the 12-volt battery to power the dashboard and interior lights. It was effectively inoperable. The vehicle displayed the following error message: "DRIVETRAIN: only electric drive possible, limited driving range, continued driving possible, consult nearest service center." We brought the car to our local BMW service center, and they ran a diagnostic (attached as PDF file). The issue is a faulty EME, which could be as much as an $11K repair. Several model years prior to 2017 i3 have been recalled by BMW for this exact issue. We cannot afford an $11K repair, so hoping BMW will recall 2017 and beyond, as this is a major safety hazard. Thankfully we were stuck in gridlock traffic and were not moving very fast (under 5 miles per hour) when the car stopped. But at a high rate of speed, this could have cause a catastrophic accident. We have two small children and will not be driving with them in this car until the issue is resolved.
