2017 BMW I3

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.

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.

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 bought the car new in 2017. Last summer, I noticed bubbles on the roof. On May 30, 2026, as I was driving 65 mph on the NJ Turnpike, I heard sounds on the roof like hard rain but it was not raining. I saw large sheets flying off my roof towards other cars, and some flying sheets were large enough to obscure a windshield. When I stopped, I saw more sheets hanging loose from the roof and I peeled off what I could. I think this is dangerous and understand it is common on BMW i3s (which are made of carbon fiber) and other BMW cars.

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?uspsharing Thanks Matt Figler (914) 715-8954

After purchasing this car used, I signed up for MyBMW remote services. My account portal stated Emergency SOS call button and crash detection services were active on my car. I decided to test, and it turns out it's not, due to the issue in SIB 84 09 22. The car will just receive a call failed message, since it's trying to do voice calls in 3G, due to the improperly programmed 4G telematics unit. So BMW knows with 100% certainty this feature will not work on the car, and the car gives no advance warning in is inoperable. Yet they are still informing me in the portal that it is active. I feel if the system is inoperable without any warning, a service bulletin without a recall is not enough. How would I have known of this issue if I didn't test it myself?

The roof is delaminating causing a danger to my vehicle and others

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).

The carbon fiber roof is bubbling and disintegrating. I have one section behind the passenger door that is the size of my FULL hand that is in a circle shape where the roof is scaling and peeling. Each day that passes, the known spot is getting bigger and bigger. It's embarrassing to see this happening to my car and makes my care look worthless. Definite eye sore. I currently have the (1) i3 EV that is the family car, (2) M3's mine is a convertible and the other is my husbands, of course, (1) M1 my son's and (1) M235 I which is my daughters. We are definitely a BMW family. Shame on BMW if they do not cover this.

The contact owns a 2017 BMW I3. The contact stated that there were discolored bubbles developing on the roof of the vehicle. The roof of the vehicle was delaminating. Upon further inspection, the contact found out that the hot climate and UV rays and the composite structure might be the factors causing the failure. The vehicle was taken to a body shop. The contact was informed that the carbon fiber used on the vehicle might have caused the failure. The vehicle was not repaired due to the cost. The manufacturer was not made aware of the failure. The failure mileage was approximately 32,000.

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.
