Hello Hyundai Tech and everyone else! My Sonata has been not wanting to start on a couple of occasions and at times seem to quit for a split second while driving along at 50mph. Then she would start but die in a minute or so, yesterday. Took her to a trusted mechanic and was told it likely had to do with a drive-shaft sensor which would be indicate by the symptoms I stated. I thought it may be dirty fuel, fuel filter (s), or pump. The mechanic said that repair meant removing the motor and that I should have the timing belt and waterpump replaced as is the timing on 75k milage indicates. Does this sound resonable to the knowledgable people in this group? Thank for any information!
