I've got 230,000 miles on my 2010 SRX, but it's not Lux - 3.0 front-wheel drive. That's not an anemic power plant. Original everything in the drive train and still going strong. Changed transmission fluid at 150,000 and getting ready to do it again. Bought after market headlight enclosures, double-sealed them before installing, and put them in myself. No issues. Sunroof gets a little damp on passenger side front in a downpour, but if I park with any uphill tilt to the car, it doesn't leak. Replaced all the lights inside and out with LEDs. Had to replace 2 rear wheel bearings and MAF sensor, but that's all the major stuff. Consistent maintenance. I love the car. YMMV. Also have a 71 Dodge Charger 500, with half a million miles on it, and a 2008 Lexus ES with only 90,000.
