Not owner surveys, not warranty statistics, not forum lore: what we actually found.

The bottom line
Engine problems dominate the fault list on the RX, with oil leaks on 56 percent of them and fuel trim out of range close behind, so your first moves are a careful under-hood inspection for seepage and a full OBD scan for those active codes. Suspension bushings crack often enough to warrant a lift check, and tire wear is another frequent hit that should come out of the asking price. Repaints show up on most examples, so treat bodywork as expected rather than a deal-breaker, but use any engine or chassis issues to negotiate aggressively or walk away if the seller won't fix them first.
