6known failure points
363NHTSA owner complaints
6safety recalls
$15,000worst-case single repair

A comfortable, capable, and genuinely nice-driving SUV that will occasionally try to bankrupt you — buy the V6 Laredo/Limited, run screaming from the diesel and the 5.7 uconnect issues.

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 2 of these are rated Critical.

20k–40k mi● Watch$0–$3,500MODERATE
ZF8HP transmission harsh/erratic shifting, TCM software faults causing hesitation or limp mode
How to catch it: Insist on the latest TCM software flash at every dealer visit even if not experiencing symptoms — many shift complaints are solved by updates that owners never get proactively.
Source: multi-source pattern (AI synthesis)
40k–70k mi● Critical$400–$15,000VERY HIGH
Oil cooler/oil filter housing leak leading to coolant-in-oil contamination on the 3.6L Pentastar
How to catch it: Check oil for a milkshake texture every oil change and replace the oil cooler proactively around 60k if it hasn't been done — this is the single biggest engine-killer on this generation.
Source: documented (NHTSA recall)
50k–90k mi● Plan$800–$2,500MODERATE
Air suspension compressor and air spring failures (Quadra-Lift equipped trims)
How to catch it: Budget for a coil-spring conversion kit (~$600) as a permanent fix if the air system starts cycling frequently rather than chasing leaks forever.
Source: multi-source pattern (AI synthesis)
60k–100k mi● Watch$0–$900MODERATE
Uconnect 8.4 head unit freezing/rebooting, backup camera dropout
How to catch it: Update Uconnect firmware via USB from Jeep's site immediately after purchase — many freeze bugs were patched but never pushed to older units.
Source: multi-source pattern (AI synthesis)
70k–120k mi● Critical$1,500–$8,000VERY HIGH
EcoDiesel EGR cooler/valve failure and HP fuel pump issues (3.0L diesel only)
How to catch it: If buying diesel, confirm both the EGR recall and the 2020 fuel pump/crank sensor recalls were performed — get the VIN checked before you even test drive.
Source: documented (NHTSA recall)
80k–130k mi● Plan$1,200–$6,000MODERATE
Rocker arm/cam follower wear on Pentastar leading to valvetrain ticking and potential head gasket issues
How to catch it: Listen for a light ticking on cold start — catching worn rocker arms early avoids cascading cam and valve damage.
