 We have had nothing but problems from our 2007 entourage.  It has been in the shop for 26 business days (m-f only) and 5 times (8000 mi).  We have the same knocking noise others have mentioned, which it has gone up in smoke for (a/c burned out) and stranded us on the interstate w/ my 4 mo old.  We have rattles/creaks etc.  Poor gas mileage.  The a/c is knocking again and we are claiming lemon law.  Just yesterday after picking it up from being at the dealer 2 weeks, the airbag light came on.  We were told they couldn't get it in until Friday (it is wed) but not to drive it b/c we won't have airbags in the event of a crash (no rentals avail). And Hyundai warranty does not guarantee a rental.
