Sister has got 2 yearold Tiida that has had "issues" since day 1. Latest problem to manifest is occaionally ( about every 4-5 days) it refuses to start until 4th or 5th try and then it runs quite normally until the next bout. The Nissan "expert" diagnosed it a fuel regulator problem, replaced $200 worth of various bits and declared it fixed. Same problem a week later. Any collective thoughts here?. Obviously one can just say take it back until it is fixed but if the expert with the Diagnostic Tool cant fix it what is the point going back?. Many thanks, John
