The most under-appreciated used sport sedan on the road — buy it, drive it forever, and laugh at your friend's BMW repair bills.
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–60k mi● Watch$300–$1,200MODERATE
Sticky/melting dashboard (soft-touch coating breaks down, especially hot climates)
How to catch it: Park in shade/use windshield sunshade and clean with dash-specific cleaner (not silicone-based) to slow the breakdown; budget for a used dash swap early rather than waiting for it to get sticky and smelly.

40k–90k mi● Plan$0–$2,500VERY HIGH
Fuel delivery pipe corrosion/leak (subject of federal recall on later 2GR-FE Toyota/Lexus V6 fuel systems, some 2010 IS VINs affected)
How to catch it: Run your VIN on the NHTSA recall lookup yourself (not just the dealer's system) and push back in writing if it's borderline — misclassification is a documented owner complaint on this exact car.

60k–100k mi● Watch$300–$700MODERATE
Front control arm bushings and sway bar end links wear, causing clunks over bumps
How to catch it: Have bushings/end links inspected at any brake service — cheap fix if caught before it accelerates tire wear.

80k–120k mi● Plan$400–$1,200MODERATE
Valve body/transmission solenoid harness wear causing harsh or delayed shifts
How to catch it: Do an ATF fluid/filter service every 60k even though Toyota calls it 'lifetime' — this single habit prevents most of these shift complaints.

100k–160k mi● Plan$600–$900MODERATE
Water pump and timing components wear on the 2GR-FE
How to catch it: Bundle water pump replacement with a timing/accessory belt service interval to save labor cost doing it twice.

120k–180k mi● Critical$1,000–$3,000MODERATE
Airbag/SRS wiring harness faults (documented in NHTSA complaints, costly to diagnose)
How to catch it: During PPI, scan for stored SRS codes even if the light isn't on — intermittent airbag wiring issues are a known weak spot and expensive to chase after the fact.
