2017 BMW I3 problems

“My 2017 i3 has a deteriorating roof. The roof, which is made of carbon fiber, is peeling and pieces are breaking off. This has also led to the interior upholstery of my roof to peel and sag. I am worried moisture will be let into my car, creating a mold issue. I contacted BMW and my extended warranty and they did not want to cover anything. They said this was normal wear and tear and they would not help me. From my understanding this is a much larger issue with all i3 models. I am also having a very hard time finding a body shop that will fix this for me. I have contacted several and they either don't know how to do it, or refuse to do it in fear that they might do it wrong. I am now considering contacting a a boat repair shop, but that might be very costly. I think the company is at fault and needs to figure out a solution. I take good care of my car and this is the only major issue I've ever had with it.”

“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.”

“The rear backup camera view in the screen is completely overridden in reverse, by a tire pressure warning when a tire is low or there is another TPMS fault. It requires using the rotary dial to clear the message before the function of the backup camera is restored. Also, if the rear hatch is unlatched by mistake (easy to do with the i3 key fob design) the rear camera, which is located in the rear bumper, is completely disabled.”

“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…”

“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…”

“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.”
