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–12k mi● Critical$0–$2,800VERY HIGH
Cracked oil pump housing on 2.4L Tigershark engine (subject of recall) causing oil leaks and potential engine damage
How to catch it: Confirm recall completion via VIN lookup before buying — this is a known manufacturing defect, not wear.
Source: documented (NHTSA recall)
20k–60k mi● Critical$150–$4,500VERY HIGH
9-speed ZF/Chrysler transmission harsh shifting, hesitation, 'Service Shifter' warnings
How to catch it: Have the TCM software updated at a dealer immediately after purchase — many shift quality issues trace to outdated calibration.
Source: documented (NHTSA recall)
30k–70k mi● Plan$0–$900VERY HIGH
Front halfshaft bearing cage failure on AWD models (recall part)
How to catch it: Verify recall completion; if a clunk appears on turns it's likely this.
Source: documented (NHTSA recall)
40k–90k mi● Critical$1,800–$6,000VERY HIGH
Power Transfer Unit (PTU) failure on AWD models — howling noise progressing to total driveline failure, sometimes taking the transmission with it
How to catch it: Check for NHTSA Campaign 25V011000 completion and listen for any howling on a test drive at 30-45 mph — walk away if present.
Source: documented (NHTSA recall)
40k–80k mi● Watch$300–$500MODERATE
Rear brake rotor warping/vibration under hard braking, often recurring after replacement
How to catch it: Upgrade to aftermarket slotted rotors instead of OEM replacements to reduce recurrence.
Source: multi-source pattern (AI synthesis)
50k–100k mi● Watch$100–$800HIGH
Electrical gremlins — backup camera static, random warning light cascades, battery drain issues
How to catch it: Keep the 12V battery and ground connections clean and tested annually — many phantom electrical faults trace back here.
Source: owner-reported (58 NHTSA complaints)
