Questions to ask the seller
- Were recalls 25V744000 (back over prevention) and 25V595000 (electrical) done? Ask for the dealer printout, or check the VIN.
- Is the airbag light off, and were any airbag recalls done?
- Do all the seat belts latch and retract?
- Do the seats adjust, heat and lock in place properly?

From this year's own recalls, top problems, top repair bills and Lexus's repair notes. Recall repairs are free at any dealer.
How serious. Out of all 3 owner complaints filed so far (every year since it was sold, not just the first 3), owners reported:
“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.
What owners complain about most. From owner complaints to the government.
Share of this year's owner complaints filed with NHTSA, not the share of cars that break. One complaint can name more than one area.

It measures complaints, not crash safety. A complaint is an owner's report, not a confirmed defect. How it works
