The automotive equivalent of a rice cooker — dull, dependable, and nearly impossible to kill if you change the oil.

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.

60k–90k mi● Plan$1,500–$4,000MODERATE
Super White (040) and Blizzard Pearl (070) clearcoat delamination — roof, hood, trunk peel down to primer
How to catch it: Call Toyota corporate with your VIN NOW and open a case under the Warranty Enhancement Program ZE7 — many owners still get free repaints if the case is documented before it spreads.

70k–110k mi● Critical$180–$4,000MODERATE
CVT (K313) shudder/judder at 30–45 mph — torque converter lockup clutch degrading, fluid breakdown
How to catch it: Do a CVT fluid drain-and-fill every 40k with genuine Toyota WS fluid — Toyota calls it 'lifetime' but the forum consensus is that's a lie that kills transmissions.

80k–120k mi● Plan$350–$650MODERATE
Water pump weep from the timing-chain-side seal (2ZR-FE)
How to catch it: Inspect the weep hole under the pump every oil change — replace at the first pink crust so you don't cook the head.

90k–130k mi● Watch$0–$150MODERATE
Rough idle / RPM dip at stoplights — dirty throttle body and carboned intake valves (Valvematic head)
How to catch it: Clean the throttle body with CRC cleaner and do the idle relearn (ignition on 30 sec, off 30 sec, start, idle 10 min in Park) — fixes the vast majority of the 500-rpm-dip complaints for free.

100k–150k mi● Plan$250–$900MODERATE
Front strut top mounts and sway bar end links — clunk over expansion joints
How to catch it: Replace end links first ($40 in parts) — 80% of the front-end clunks are end links, not struts.

120k–180k mi● Watch$150–$500MODERATE
Airbag warning light returns after the Takata inflator recall repair — often just a seat-occupancy sensor or clock spring
How to catch it: Pull the code with a bidirectional scanner (Techstream) before paying a dealer — half the time it's a $20 seat harness reseat under the passenger seat.

130k–200k mi● Watch$25–$180MODERATE
Halogen headlight housings hazing/yellowing — night vision falls off a cliff
How to catch it: 3M restore kit + a coat of UV clear ($30 total) beats replacing housings and matches the LE Premium/Eco look.
