The boring-but-brilliant three-row that just keeps running — buy it with confidence, just get the V6.
Every documented failure, earliest first
Ordered by the mileage the problem typically appears. VERY HIGH
confidence means it's tied to a documented NHTSA recall, and 1 of these are rated Critical.
0k–30k mi● Watch$1,500–$4,000MODERATE
Factory clear coat/paint delamination (especially Blizzard Pearl 070)
How to catch it: Document any peeling early and push for a Toyota goodwill paint claim — this is a known factory defect on this color code.

40k–70k mi● Plan$300–$700MODERATE
Power liftgate motor/actuator failing mid-stroke
How to catch it: Lubricate the liftgate struts/tracks annually and stop forcing the gate if it stalls — resetting the ECU sometimes buys time before replacement.

50k–90k mi● Plan$400–$900VERY HIGH
Entune infotainment head unit freezing/rebooting, sometimes with steering assist hiccup
How to catch it: Check for the latest Toyota TSB software update at the dealer before paying for a new head unit — many units were fixed with a firmware flash.
Source: documented (NHTSA recall)
60k–100k mi● Watch$400–$900MODERATE
Front strut mounts and sway bar link wear causing clunks over bumps
How to catch it: Have the front end inspected at 60k for play in the sway bar end links — cheap fix if caught early, but ignored it turns into full strut replacement.

90k–130k mi● Watch$150–$350MODERATE
Door lock actuators failing (won't lock/unlock via fob or interior switch)
How to catch it: Replace actuators proactively on high-use doors (driver's side first) once you notice intermittent locking behavior.

100k–150k mi● Critical$1,200–$2,500MODERATE
U660 6-speed automatic valve body/solenoid wear causing harsh or delayed shifts
How to catch it: Do a transmission fluid drain-and-fill every 60k even though Toyota calls it 'lifetime' fluid — this dramatically extends valve body life.
