Right now at 3 weeks ownership and just under 1000 miles I'll give my $.02 on this SUV (like anyone cares). This is the FWD LT package with the sun/sound option.
Likes: So far pretty decent fuel economy for a larger vehicle. I drive fairly conservatively and I'm learning to hypermile a bit without irritating other drivers.
Road noise is minimal at highway speeds and the suspension handles Minnesota's awful roads well.
Has plenty enough power to get up to highway speeds on the onramps. Wife thinks it's fine, and her last car was a Saturn Aura XR 3.6.
Seats are comfortable (no leather), the drivers seat has multiple power adjustments (passenger seat doesn't) and the heated seat option works great.
Sound system is really nice and I'm getting the hang of using Android Auto. I mainly use Waze for navigation and Pandora for streaming music. The 8" touchscreen display is easy to see (except in bright sunlight) and reacts well to inputs.
Nice having multiple USB ports in the front and rear.
Rear seat comfort is good with plenty of space for passengers.
Rear cargo space is decent and the I like the fold flat rear seats with the seat releases in the back.
Stock horn is plenty loud and I don't think I'll be adding any extras (like I did with my Rav4).
Dislikes: Stop/Start function seems to have a mind of it's own. I finally figured out that it won't work until the engine is up to operating temps, if the vehicle is stopped on an incline or stopped with the wheels turned. Other than that it works well and I can usually time stoplights so right before green releasing the brake pedal the engine fires right up.
Transmission needs a lot of throttle for downshifts, although the Saturn had the same characteristics. So if you need to pass someone RIGHT NOW you pretty much have to firewall the gas pedal.
The switches for the sunroof and shade could be a little more pronounced- I have to look at the roof control panel to make sure I'm hitting the right one but I'm sure over time I'll figure it out so I don't have to take my eyes off the road.
The stock tires wander a bit over crowned roads but not too extreme, just a minor annoyance.
I have yet to crawl underneath and see how to change the oil/filter but reading other reports online it seems simple enough. Maybe someone can explain why this engine uses a spin on filter and my previous HHR 2.2 Ecotec used a cartridge type on the top.
Other than that I'm happy with the Nox and more importantly the wife's happy with it.
