I got the PPI on the last one. SO I know whatever it wasn't a SERIOUS issue. But, I did trade in an 09 RRS for it. My wife lost confidence in the X after three visits and new set of tires (at no cost to me) didn't fix the vib. Not mention the "did we get rid of my truck for a..." convo that kept coming up. It wasn't awful, but any vibration for, like you said, a luxury vehicle...not acceptable.

But that's the beauty of a credible dealership, they were willing to make the customer happy. PPI is good, but if you buy at from a bad dealership....just as bad as getting one without the PPI IMO
