Common Problems & Known Issues

The 2013 Durango is a solid three-row SUV built on the Mercedes ML platform, but the 3.6L Pentastar suffers catastrophic cylinder head failures and the 5.7L Hemi has notorious lifter issues. Both share a cooling-related transmission weakness that kills units prematurely if ignored.

3.6L Pentastar Cylinder Head Failure (Left Bank)

Common · high severity
Typical onset: 80,000-130,000 mi
Symptoms: Coolant loss with no visible leaks, White smoke from exhaust on cold starts, Misfire codes P0301-P0303, Oil contamination in coolant reservoir, Overheating under load
Fix: Left cylinder head cracks between valves due to casting defect. Requires complete head replacement, machine work, timing chain service while apart. 12-16 hours labor. Many shops recommend doing both heads while engine is apart to prevent repeat failure.
Estimated cost: $3,500-5,500

5.7L Hemi Lifter and Cam Failure

Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Cold-start ticking that persists beyond 30 seconds, Check engine light with multiple misfire codes, Loss of power on one or more cylinders, Metal shavings in oil, Camshaft position sensor codes
Fix: MDS (cylinder deactivation) lifters fail, wiping cam lobes. Requires camshaft, all 16 lifters, often rockers and pushrods. If debris circulated, complete teardown for bearing inspection. 18-24 hours labor minimum, can escalate to short block if bearings damaged.
Estimated cost: $4,000-8,000

Transmission Oil Cooler Line Failure and Contamination

Common · high severity
Typical onset: 70,000-120,000 mi
Symptoms: Strawberry milkshake appearance in coolant reservoir, Transmission slipping or delayed engagement, Overheating transmission, Coolant in transmission pan, Radiator failure accompanies this
Fix: Oil cooler inside radiator fails, allowing coolant and ATF to mix. Requires new radiator, complete transmission flush and filter, often torque converter replacement. If driven after mixing, full transmission rebuild needed. Cooler line replacement 4-6 hours; full trans rebuild adds 12-16 hours.
Estimated cost: $1,200-2,500 for cooler/flush; $3,500-5,000 if transmission damaged

TIPM (Totally Integrated Power Module) Failures

Occasional · high severity
Symptoms: Intermittent no-start conditions, Fuel pump not priming, Wipers activating randomly, Horn honking on its own, ABS/traction control lights with no codes, Power windows failing
Fix: Central control module develops internal relay and circuit failures. Dodge issued TSB and recalls for some symptoms. Requires TIPM replacement and programming. 2-3 hours labor plus programming time. Used units often fail similarly; recommend new or remanufactured with warranty.
Estimated cost: $800-1,500

Front Lower Control Arm Ball Joint Separation

Occasional · high severity
Typical onset: 80,000-130,000 mi
Symptoms: Clunking over bumps from front end, Wandering steering or pull to one side, Uneven tire wear on inside edge, Visible play when prying on wheel, Front end feels loose at highway speeds
Fix: Ball joints are pressed into control arms and fail prematurely. Some technicians attempt pressing new joints, but arms often crack during removal. Recommend complete control arm assemblies both sides. 3-4 hours labor for both sides, includes alignment.
Estimated cost: $800-1,200

Rear Differential Pinion Seal Leak

Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Gear oil dripping from front of differential, Low fluid causes whining noise during acceleration, Oil staining on driveshaft and undercarriage, Burning oil smell after highway driving
Fix: Pinion seal hardens and leaks. Requires driveshaft removal, pinion nut torque spec is critical (requires holding tool and inch-pound measurement). If preload is lost, bearing replacement required. 2-3 hours labor for seal only; 6-8 hours if bearings needed.
Estimated cost: $400-700 seal only; $1,200-1,800 with bearings

Evaporative Emissions System Leak (Fuel Tank Vent Valve)

Occasional · low severity
Typical onset: 80,000-120,000 mi
Symptoms: Check engine light P0455 or P0456 (large/small EVAP leak), Fuel smell near tank after fill-up, Hissing sound when opening fuel cap, Difficulty fueling (pump clicks off repeatedly)
Fix: Vent valve on top of fuel tank fails. Tank must be dropped for access. Often combined with fuel pump replacement if age-appropriate. 3-4 hours labor for tank drop and valve replacement.
Estimated cost: $500-900
Owner tips
  • Change oil every 5,000 miles maximum with quality synthetic on Hemi engines—MDS system is brutal on oil
  • Flush transmission fluid every 60,000 miles and inspect cooler lines at radiator for seepage
  • Install auxiliary transmission cooler if towing regularly—factory cooler is marginal
  • On 3.6L engines, monitor coolant level obsessively after 70K miles—early detection prevents complete engine failure
  • Use Mopar-spec ATF+4 only in transmission—aftermarket fluids accelerate failure
Pass on high-mileage examples unless engine and transmission have documented replacements—both powertrains have catastrophic design flaws that cost more to fix than the vehicle is worth.
