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.
0k–200k mi● Watch$40–$300MODERATE
Hardtop and freedom-top leaks at the header seal and side rails
How to catch it: Replace the header seal proactively ($60) and treat all rubber seals with 303 Aerospace Protectant twice a year.

40k–80k mi● Critical$150–$1,200MODERATE
Death wobble — worn track bar bushings, ball joints, or steering stabilizer causing violent front-end oscillation
How to catch it: Torque the track bar bolt to spec now and inspect ball joints — a $200 adjustable track bar and fresh bushings preempts the scariest thing a JK does.

60k–100k mi● Plan$400–$900MODERATE
Oil cooler housing leak (plastic housing on top of Pentastar warps and seeps into valley)
How to catch it: Replace the plastic oil filter/cooler housing with the aluminum Dorman 926-876 unit before it fails — $150 part vs coolant contamination and hours of labor.

70k–120k mi● Plan$600–$1,800MODERATE
Exhaust manifold cracks / broken manifold bolts (Pentastar left-side manifold is notorious)
How to catch it: Listen for a cold-start tick that fades as it warms — that's the tell; catching a broken stud early saves a head-off extraction job.

80k–150k mi● Critical$800–$2,000VERY HIGH
ABS module internal fault (C2200 code) — Mopar backorder, no OEM replacement, aftermarket rebuilds $800–$1,500
How to catch it: This is the JK's current crisis — Module Master and BBA Reman rebuild yours for ~$400 with a core; keep a spare on the shelf if you find one cheap.

90k–130k mi● Watch$150–$800MODERATE
Rear main seal / oil filter housing seep, and window regulator failure (drop into the door)
How to catch it: Window regulator clips are a known failure — a $40 metal-clip kit installed proactively beats a $300 regulator replacement.

100k–200k mi● Critical$0–$4,000VERY HIGH
Frame/body rust at rear control arm mounts, tub corners, and skid plate seams (Rust Belt trucks)
How to catch it: Fluid Film or Woolwax the frame and undercarriage every fall — this is the difference between a $30k JK and a scrap-value JK in 5 years.
