I've had my 07 Greenline for about 14 months. Have not had any trouble with it. Did receive two recall notices during that time, took it in to the shop had the required work done. No other shop time except scheduled maintenance.
There were problems with the earlier battery design, which caused many of the problems that you may have read about.
Have did two road trips last year, one 5,600 miles and the other about 1,000 miles without worries. Have a 6,000 mile trip upcoming on the schedule. Not worried about taking my VUE.
I am a very satisfied owner of the VUE Greenline.
