I've had my new RDX for 3 days and already problems. The driveshaft is warped and is causing a vibration throughout the entire vehicle. I noticed this on the drive home from the dealership. Dealer will be replacing the driveshaft tomorrow. Today I noticed that the suspension squeaks over speed bumps and dips in the road. Fun times. And to think that I gave up a perfectly good 2004 Nissan Pathfinder that has NEVER been back to the dealer for a defect or breakdown. I hate to see what 3 months or 3 years will bring.
