All 8 documented failure points for this exact year — what goes wrong, when,
what it costs, and how to spot it on a test drive. Free, from Milo's research on this model.
8known failure points
1430NHTSA owner complaints
18safety recalls
$8,000worst-case single repair
Great truck, cursed drivetrain choices — buy the 5.7 Hemi, run screaming from the EcoDiesel
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.
60k–90k mi● Critical$900–$2,000VERY HIGH
ABS module failure (part 68228991AD) — ABS, traction, and cruise lights all illuminate; part is famously back-ordered/unavailable from Mopar
How to catch it: Send the module to Module Experts or BBA Reman for a mail-in rebuild ($400–600) BEFORE it fails hard — much cheaper than an emergency scramble when Mopar has none in stock.
Source: documented (NHTSA recall)
60k–120k mi● Critical$2,000–$8,000VERY HIGH
3.0L EcoDiesel EGR cooler cracking / oil cooler failure / injector leaks — cascades into recalls 22V-406, 20V-041
How to catch it: Confirm every diesel recall (EGR cooler, HPFP, crank sensor) is closed at the dealer; if buying, walk unless service records show these done — parts availability is brutal.
Source: documented (NHTSA recall)
60k–100k mi● Watch$0–$400MODERATE
8HP70 (ZF 8-speed) rotary shifter software glitches and harsh 2-3 shifts
How to catch it: Do a ZF Lifeguard 8 fluid + pan/filter swap at 80k despite Chrysler's 'lifetime' fluid claim — this is the single best thing you can do for the trans.

70k–110k mi● Critical$1,200–$2,400VERY HIGH
Electronic power steering (EPS) intermittent failure — steering goes heavy then returns; often traced to connector contamination or the rack assembly
How to catch it: Verify recall 16V-666 was completed on this exact VIN at a dealer; if not, get it done free before purchase — otherwise budget for a rack.
Source: documented (NHTSA recall)
80k–130k mi● Plan$3,500–$6,500MODERATE
5.7L Hemi 'tick' — lifter/cam failure on MDS cylinders (typically #2 and #7)
How to catch it: Run full-synthetic 5W-20, change every 5k not 10k, and disable MDS via a Range device or tune — hugely reduces lifter cycling on cylinders 1/4/6/7.
Source: multi-source pattern (AI synthesis)
80k–120k mi● Watch$400–$1,200VERY HIGH
Exhaust manifold bolt shear / manifold ticking on 5.7 Hemi
How to catch it: Do the fix at the first tick — replacement studs and gaskets are cheap; ignoring it warps the manifold and turns it into a full replacement.
Source: documented (NHTSA recall)
90k–140k mi● Plan$800–$1,800VERY HIGH
Air suspension compressor failure / height sensor faults (on Laramie Longhorn/Limited/Rebel with air ride)
How to catch it: Cycle the suspension through all height modes weekly to keep seals lubricated; Arnott makes an aftermarket compressor for ~40% less than Mopar.
Source: documented (NHTSA recall)
100k–150k mi● Watch$150–$400MODERATE
Rear axle pinion seal leak / rear diff cover weep
How to catch it: Change diff fluid at 60k with a quality 75W-140 synthetic and check the fill plug torque; catches the seal before it soaks the driveshaft.
