NHTSA complaint #11534645

Owner complaint summary

BMW "did not" issue a recall notice for this known issue for my VIN. They were aware of this issue and corrected it based on the latest software update 11/2022.56. The problem is older software versions can cause the battery to completely drain even when the engine is not running and make you deserted anywhere, which is a safety issue. Also, since the battery can be fully drained, your booster brakes also will not work during the start of the engine, which can again cause risk when starting. BMW did not advise customers regarding this safety issue. In my case, My battery was completely drained, and I had to replace my battery. Details of the defect from the latest software update release notes are mentioned below. The concern is why BMW did not issue a recall notice to customers like me. I hope NHTSA can take the necessary action on this and issue a proper recall notice.
