NHTSA Complaint #11596458 — 2008 BMW M3

During a regular fuel stop at a gas station, I noticed the central lock button nor the physical door hinge fail to operate to open the door for me to exit. The fuse for the central power door lock/unlock button blew out, completely disabling the interior door hinge mechanism. I got trapped inside but thankfully the power was still on and the rear doors remained unlocked. So, I lowered the driverside window and crawl outside. Then open the unlocked reer door to enter the vehicle from the back seat. Then located the fuse box, searched on the internet to itenfy the effected fuse, replaced damaged one to another fuse (dedicated to another function), temporarily replaced with the same ampage fuse. For my vehicle, there is no visible solution to enter the physical key to open the door from the outside that are typically found under the exterior door handle. If it wasn't for a combination of luck that the other door remained unlocked, had power to lower the window, have some knowledge of vehicle electrical system (fuse), and tolerable weather condition, I would've been stuck inside my car for indifinite time, or break the window to get to exit. I would testify that this is a serious safety concern the manufacturer should investigate and provide permanent resolution.
