We've owned this 2007 SRX AWD V-6 about 4-years. It now has 90K miles. The car has been very reliable, and we've only ever paid for routine maintenance. There are a few problems you should be aware of. (1) The engine consumes several qts. of oil between changes. (2) The build integrity is fair-poor, as evidenced by numerous squeaks and rattles. (3) The passenger foot-well is extremely narrow, and uncomfortable. (4) Fuel mileage is much lower than advertised. We experience 15/20.
Ride is superb for long trips; almost like driving your sofa. AWD system works well.
If you're in the market, I'd suggest avoiding the V-6 in favor of the V-8. The six is under-powered and its purported fuel economy seems a false promise.
