Filed Sep 28, 2026 · SC

Active Grill shutter malfunction. Randomly the check engine light came on the code was for the grill shutter. Upon inspection the grill shutter is not closing. This was an extended warranty on several prior X3/ X5 models. This appears to be the same issue, I wanted to make BMW aware so they can reevaluate the extendeded warranty.

To Whom It May Concern, I am submitting this formal safety complaint regarding my 2021 BMW X3, which is currently subject to an active safety recall involving a potential engine starter defect that may result in a vehicle fire.BMW of North America has notified me that water may enter the engine starter, causing corrosion and overheating, which can lead to a fire even when the vehicle is parked and turned off. BMW has advised owners, including myself, to park the vehicle outside and away from structures due to this risk.Since receiving this recall notice, my vehicle has displayed a check engine light, and I have personally experienced a burning or fire-like smell coming from the engine compartment.These symptoms have caused serious concern for my safety and the safety of my child.I contacted BMW regarding this issue and was informed that there is currently no available remedy to repair the defect. Despite the known fire risk and the warning signs my vehicle is exhibiting, BMW has not provided a temporary repair, replacement vehicle, or other permanent solution.This vehicle is my only means of transportation. I am a single mother and rely on this vehicle daily to transport myself and my child to work, school, and essential activities. Being advised to continue driving a vehicle with a known fire hazard, while also being instructed not to park it in my garage, places an unreasonable and unsafe burden on my family.I am not refusing a reasonable solution. I am open to trading my vehicle into a comparable BMW model while maintaining the same existing car note or loan terms. My primary concern is having a safe and reliable vehicle for myself and my child, given the unresolved safety defect and the lack of an available repair.I am submitting this complaint so that the federal safety agency is aware that consumers are currently operating vehicles with a known fire risk and no available remedy. I respectfully request the federal safety agency’s review and assistance me .

The malfunction involves the collision warning system and sudden braking functionality. The dealership inspection identified a problem with the KAFAS (camera) unit, specifically its housing being deformed from heat, which affected the functionality of the collision sensor and caused the system to malfunction intermittently. The component is still installed in the vehicle and available for inspection if required. The system triggered sudden braking without an actual threat, creating a serious risk of being rear-ended by vehicles behind me. This issue has occurred twice in the last month, with no warning or actual collision risk present. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the problem was confirmed by the dealership. Their inspection found that the KAFAS camera housing is deformed due to heat exposure, causing malfunction warnings and erroneous braking behavior. They stated this is not a covered warranty issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The dealership performed an inspection and provided an inspection report, but no other entities (e.g., manufacturer, police, or insurance representatives) have inspected the component or vehicle. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes, the malfunction indicator light for the collision sensor appeared intermittently. The dealership’s report attributes this to the deformation of the KAFAS camera housing due to heat exposure.

Intermittent Check Engine Light with the Plug In Hybrid X3 30e since January 2023. Vehicle has been taken back to BMW 2 times and released back to me without permanent fix. Vehicle as of April 2023 is currently held at dealership for 3rd time still without fix. Each check engine light results in a trip back to the dealership service center because we wouldn't know what is the severity of the issue. My safety is put at risk because a normal drive suddenly becomes worrisome and interrupted at random times and we have to attempt to safely pull over to call roadside assistance. Currently in communication with local dealership and have reached out to BMW Customer Relations without response yet.

The check engine light is on. We have taken the vehicle to 2 different BMW dealerships and the problem persists. I have contacted BMW of North America and they have not responded. We are hesitant to drive this vehicle since it is unknown why the "check engine" light is on. Thank you.
