About 20% of time, driver side seat belt jams, will not release from recess/retainer behind seat without using my hand for couple minutes to jiggle enough. no problem once i get it to release. then fits in connector and also releases ok. two local dealers unable to fix. one even replaced entire mechanism, still jams. manager said this model seems to have this problem. this occurs at a stand still, before putting car in gear, sometimes with motor on, sometime before i start the engine. sometimes just opening the door causes the release. other times, i have to put my hand under the belt and maneuver the belt until it relates from the retainer into which the belt retracts. no pictures included. just a standard seat belt. had a bmw 3351 for 7 years. never had this problem once.
