2018 DODGE DURANGO

Typical onset: 60,000-90,000 mi

Symptoms: Milky pink fluid in radiator overflow tank (coolant-trans fluid mixing), Transmission slipping or delayed engagement, Overheating transmission warning light, Strawberry milkshake appearance in coolant reservoir

Fix: Internal radiator transmission cooler fails, allowing coolant into trans fluid and destroying transmission. Requires radiator replacement, external cooler install, full transmission rebuild or replacement, complete fluid system flush. 12-18 labor hours for full repair with rebuild.

Estimated cost: $3,500-6,500

Typical onset: 80,000-130,000 mi

Symptoms: Sudden catastrophic misfire on one or more cylinders, Metallic rattling from engine at idle, Check engine light with multiple misfire codes, Complete loss of compression on affected cylinder(s)

Fix: Exhaust valve seats drop out of cylinder head, falling into combustion chamber and destroying piston, cylinder wall, and sometimes crankshaft. Requires complete cylinder head work or replacement, often full long block replacement if piston debris damages crank. 20-28 labor hours for long block swap.

Estimated cost: $7,000-12,000

Typical onset: 40,000-80,000 mi

Symptoms: Vibration or shudder during light acceleration at 25-50 mph, Hard downshifts when slowing or coming to stop, Clunking when shifting from Park to Drive, Hesitation before engaging gear from stop

Fix: Torque converter clutch develops shudder, transmission mounts wear prematurely. Often requires torque converter replacement and software flash, sometimes full rebuild if wear is advanced. Mount replacement adds 1.5 hours. Converter job 8-12 hours, rebuild 14-18 hours.

Estimated cost: $2,200-5,800

Typical onset: 70,000-110,000 mi

Symptoms: ABS and traction control warning lights illuminated, Loss of ABS function and stability control, Brake pedal feels spongy or travels further than normal, Intermittent loss of power brake assist

Fix: Internal corrosion or electrical failure in ABS hydraulic control unit, covered by recalls in some cases but widespread beyond recall scope. Requires module replacement and brake system bleed. Unit must be programmed to VIN. 3-4 labor hours.

Estimated cost: $1,800-2,800

Typical onset: 50,000-90,000 mi

Symptoms: Oil dripping from front of engine onto ground, Coolant loss with no visible external leak, Oil contamination in coolant or vice versa, Ticking noise from engine that worsens when cold

Fix: Plastic oil filter housing and integrated oil cooler cracks, coolant crossover tube leaks. While accessible, timing cover and water pump often need replacement at same time due to age. 6-9 labor hours for comprehensive front-end seal job.

Estimated cost: $1,400-2,600

Typical onset: 60,000-100,000 mi

Symptoms: Vibration that increases with vehicle speed, especially 45-65 mph, Clunking when accelerating or decelerating, Squeaking or grinding from under vehicle center, Vibration worse when turning in 4WD

Fix: U-joints wear out, center support bearing fails, or driveshaft becomes unbalanced. Many techs replace entire driveshaft assembly rather than service joints due to staked design. 2-3 labor hours.

Estimated cost: $600-1,200

Symptoms: Rapid clicking or ticking from dashboard, especially on startup, Temperature inconsistent between driver and passenger sides, Airflow stuck on defrost or floor only, Clicking noise increases when adjusting temperature

Fix: Plastic blend door actuators strip gears or motors fail. Multiple actuators in system; diagnosis requires listening to pinpoint which one. Dash access varies by location — some 1 hour, recirculation door requires full dash removal (8-10 hours).

Estimated cost: $180-1,500
