What year is your Quest? Obviously this Quest was not shown any love by the mechanic. I own a 2004 Quest S with 135,000 miles. I haven’t had as many problems as others but there ae a few consistent problems that are maddening. LIke the undersized brakes that keep warping; the Plastic interior that breaks verys easily and the rattling driver’s side door (never been in a accident), to name a few things. I didn’t mention the radio that cuts off or the transmission module that acts up and forces to you to pull over and re-start the van.
Nissan struggled with the 2004 re-design. Nice looking vehicle but the engineering was lacking. Lots and lots of issues.
