The 2019 Durango rides on Chrysler's aging WK2 platform with proven V6/V8 powertrains but persistent transmission cooling issues and electrical gremlins that plague FCA products of this era. The 3.6L Pentastar is generally reliable; the Hemis run strong but can burn oil at higher miles.
Transmission Oil Cooler Failure / Fluid Cross-Contamination
Common · high severityTypical onset: 40,000-90,000 mi
Symptoms: Transmission slipping or erratic shifting, Milky/pink transmission fluid (coolant mixing), Engine overheating or transmission overheating warnings, Transmission failure shortly after cooler leak begins
Fix: Replace transmission oil cooler, flush both cooling system and transmission completely, sometimes requires transmission rebuild if contamination went unnoticed. 6-12 hours labor depending on damage extent.
Estimated cost: $800-$1,200 cooler only, $3,500-$5,500 if transmission rebuild needed
ABS Module / Electronic Stability Control Failure
Common · high severityTypical onset: 50,000-100,000 mi
Symptoms: ABS/ESP/BAS warning lights illuminated, Loss of stability control and traction control, Hard brake pedal or extended stopping distances, Codes C121C (pump motor circuit) or C2200 (internal module fault)
Fix: Replace ABS hydraulic control unit (not rebuildable). Requires bleeding entire brake system. 2.5-3.5 hours labor. Recall 23V-384 covers some units but not all failure modes.
Estimated cost: $1,800-$2,800
Backup Camera Failure / Intermittent Operation
Common · low severitySymptoms: Black screen or 'Service Rear Park Assist' message when shifting to reverse, Intermittent camera operation, works when it wants to, Distorted or snowy image, Grid lines missing or misaligned
Fix: Usually corroded connector at liftgate or failed camera module itself. Clean connectors first (0.5 hrs), replace camera if needed (1.5 hrs). Recall 20V-541 addressed some wiring issues but didn't cover all failures.
Estimated cost: $50-$150 connector repair, $350-$550 camera replacement
3.6L V6 Rocker Arm / Lifter Failure
Occasional · high severityTypical onset: 80,000-140,000 mi
Symptoms: Ticking or tapping noise from engine, especially cold start, P0300 random misfire or individual cylinder misfire codes, Loss of power, rough idle, Check engine light with codes related to cam/crank correlation
Fix: Replace failed rocker arms and inspect camshaft lobes for wear. Often requires cylinder head removal for proper access. 8-14 hours labor. If cam lobes damaged, complete valve job needed.
Estimated cost: $1,500-$2,500 rocker arms only, $3,500-$5,000 if heads need work
5.7L/6.4L Hemi Excessive Oil Consumption / Piston Ring Failure
Occasional · medium severityTypical onset: 60,000-120,000 mi
Symptoms: Burning 1+ quart every 1,000-2,000 miles, Blue smoke from exhaust on acceleration or startup, Fouled spark plugs (oil-soaked), Low oil pressure warning if neglected
Fix: Requires complete engine teardown: new pistons, rings, honing cylinders, often new bearings. 20-30 hours labor for proper rebuild. Some shops opt for reman long block swap at 18-22 hours.
Estimated cost: $5,500-$8,500 in-frame rebuild, $7,000-$10,000 long block replacement
Rear Differential Pinion Bearing Failure (AWD/RWD Models)
Occasional · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Whining or howling noise from rear that increases with speed, Clunking when accelerating or decelerating, Vibration through floor at highway speeds, Grinding noise in severe cases
Fix: Rebuild differential with new bearings, seals, and often ring/pinion gear set. 4-6 hours labor. Recall 23V-386 covers some early failures but limited scope.
Estimated cost: $1,200-$2,200
Transmission Mount Failure (All Models)
Common · low severityTypical onset: 60,000-100,000 mi
Symptoms: Clunk when shifting from park to drive or reverse, Excessive vibration at idle in drive, Visible engine movement when revving in park, Transmission shifter feels loose or notchy
Fix: Replace transmission mount and inspect engine mounts while accessible. 1.5-2.5 hours labor. Cheap insurance against driveline damage.
Estimated cost: $250-$450
Solid SUV if you get a good one and stay ahead of the transmission cooling issue, but budget $2,000-3,000 for unexpected repairs in the first year of ownership — that ABS module or trans cooler will likely be your welcome gift.
