We now have 167,000 miles on our van and we have had no major problems with it. The AC needed work at 112,000 and the rear lights (including back up sensors) went bad at 125,000 but we bought parts at a junk yard and everything is still going great.
I hate this van! The seat heaters quit working,can live w/that, the speakers SUCK. Power door on the passenger side not only doesn't work but will not unlock w/the electronic locks or manually so it can't be opened at all. I've replaced Battery, thermostat, heater/AC blower motor, the resistor(that melted), water pump, belt, Intake Manifold gaskets(top &bottom), heater hose. The entire engine cooling system & heater/AC system cannot handle the pressure &original parts corrode quickly! It's fuel injected but have to give it gas to start it. And now it needs a new Harmonic Balancer-because they couldn't just bolt on the pulley for the belt, they used something rubber that corrodes too!
Plenty of room for hauling kids, work stuff, etc. MAJOR ISSUE with electrical system. One little short in electrical system and you will have constant problems that pop up out of nowhere. Especially with so many features requiring that electrical system to stay up and running.
I have over the past 10 years poured a lot of money into this van . While I like the leather seats and all the options being a premiere edition the intake and head gaskets went twice a transmission rebuild ones at 85000 miles heated seats repaired twice broke again had way to many over heating problems just to many things to list .If you like big repair bills by a GM mini van. The van spent more time being repaired than me driving it never get me again GM.
I didn't have this car at 3500 miles when others lost transmissions, but I have had it at 60k (lost again). Now I hear I need to fix it again (jarring gears). I included traction control problems last time. I did not run it hard (I drive like grandma on purpose) but it did not solve this $4000 later. It runs quiet and smooth sometimes, but I can't put off a transmission repair for complications failure would have - seen elsewhere. It was in the shop a long time despite being partially covered by a plan and monitored for that. They damaged some other features while fixing it at an approved GM dealership (i.e. driver seat warmer).
