You are right about the Edge and Grand Cherokee. Nice cars, poor reliability.
The Lexus RX350 is a great car, probably the most reliable luxury car, not fun to drive, but is very comfortable. Great road trip car. It's the best selling luxury vehicle in the U.S. so I guess it's the Camry of luxury SUVs for better or worse.
I don't like the Acura RDX, but some people do for its simplicity and how it feels like a Honda. It's just not competitive with most other luxury crossovers. It is reliable though.
I rented an Infiniti QX70 a few years ago and I thought it was fun to drive. The ride was too harsh for my taste, but loved the sound system. Great driver's car, but not for road trips. The interior was very small and sort of cramped, one of the less practical SUVs. My favorite part was the signature Inifiniti exhaust note; the car sounds awesome. Reliability is iffy. I'm not a fan of Nissan, but I really liked the QX70 because it's unlike most SUVs today.
I haven't driven the XC60, but I've heard the seats are comfortable. It isn't reliable so that's probably a deal breaker. Older interior than the other SUVs.
I'm assuming the Pilot replacement is the RX350 and the Ridgeline replacement is the Infiniti, Volvo, or Acura?
