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 3 of these are rated Critical.
40k–80k mi● Critical$6,000–$8,000VERY HIGH
Theta II 2.0T/2.4L GDI rod bearing knock leading to engine seizure (Sport models)
How to catch it: Enroll in Hyundai's Knock Sensor Detection System (KSDS) software update NOW — it flashes a code before catastrophic failure and preserves your lifetime powertrain warranty claim.
Source: documented (NHTSA recall)
60k–120k mi● Critical$5,000–$14,000MODERATE
3.3L Lambda II V6 excessive oil consumption and rare connecting-rod-through-block failure
How to catch it: Do 5,000-mile oil changes with full synthetic and check oil level every other fill-up — document everything; oil-consumption tests at the dealer are your ticket to a free engine.
Source: multi-source pattern (AI synthesis)
60k–100k mi● Plan$150–$2,500MODERATE
Harsh 1-2 shift / delayed engagement on cold starts (6-speed A6MF2)
How to catch it: Drain-and-fill with genuine Hyundai SP-IV fluid every 60k — do NOT let a quick-lube shop flush it or use universal ATF.

70k–100k mi● CriticalvariesVERY HIGH
ABS/HECU module internal short — fire risk (recall 22V-056)
How to catch it: Check recall status by VIN on NHTSA.gov before purchase; until fixed, park outside and away from structures — Hyundai's own advisory.
Source: documented (NHTSA recall)
80k–120k mi● Watch$300–$600MODERATE
Front strut mount clunk and sway bar end-link rattle over bumps
How to catch it: Replace end links first ($40 part) — 80% of the clunks blamed on struts are actually $80 end links.

90k–130k mi● Plan$400–$700MODERATE
GDI carbon buildup on intake valves causing rough idle and misfires
How to catch it: Run a can of CRC GDI Intake Valve Cleaner every 20k miles and use Top Tier fuel — delays the walnut blast by 40-50k.

100k–160k mi● WatchvariesVERY HIGH
Secondary hood latch corrosion — hood can fly open (recall 19V-757)
How to catch it: Lift the hood and manually click the secondary latch monthly; if it feels sticky, spray with white lithium grease.
