Hi. Maybe a rare problem ? When trying to start the (2 yr old) van, the ignition key turns past the usual spring-loaded stop (where it usually starts the engine) and just keeps turning round in the lock without "catching" anything, multiple times. Feels rough but not hard to turn. Not affected by steering lock. Key could be removed. After a few tries in and out it worked as normal. This has happened 2 times now, 2 weeks apart. Is this a sign of impending total failure, or a "design feature"?? Thanks for any suggestions, TTKT.
