The 2017 Journey is essentially a carryover of FCA's aging JC platform with known weak points in the transmission cooling system, engine oiling issues on the 2.4L, and electrical gremlins. It's the last generation of a crossover that overstayed its welcome, so parts availability remains decent but fundamental design flaws persist.
Transmission Oil Cooler Failure (All Engines)
Common · high severityTypical onset: 60,000-100,000 mi
Symptoms: Transmission fluid mixing with coolant (strawberry milkshake appearance in overflow tank), Erratic shifting or slipping, Transmission overheating warnings, Check engine light with transmission-related codes
Fix: Replace transmission oil cooler assembly, flush cooling system completely, replace transmission fluid and filter. If contamination occurred, transmission rebuild or replacement is often required within 5,000-10,000 miles. Labor alone is 3-5 hours for just the cooler, 12-18 hours if the transmission needs internal work.
Estimated cost: $800-1,200 for cooler only; $2,800-4,500 if transmission contamination requires rebuild
2.4L Tigershark Engine Oil Consumption and Bearing Failure
Common · high severityTypical onset: 70,000-120,000 mi
Symptoms: Excessive oil consumption (1 quart per 1,000 miles or worse), Engine knock or rattling on cold start, Check engine light with misfire codes, Complete engine seizure if oil runs critically low
Fix: Root cause is piston ring design and inadequate oil flow to connecting rod bearings. Fix requires complete engine rebuild or replacement with updated pistons and rings. Some owners limp along adding oil religiously, but bearing failure leads to catastrophic damage. Engine R&R with rebuild is 16-22 hours labor.
Estimated cost: $4,500-7,000 for remanufactured engine installed; $5,500-8,500 for rebuild with updated internals
Alternator and Wiring Harness Issues
Occasional · medium severityTypical onset: 80,000-130,000 mi
Symptoms: Battery warning light intermittent or constant, Electrical accessories cutting in and out, No-start condition despite good battery, Burnt smell near engine bay, melted wiring insulation
Fix: Alternator failures are typical for mileage, but corroded or undersized wiring connections cause repeat failures. Inspect and repair/replace affected harness sections when doing alternator. Budget 2-3 hours labor for alternator, add 1-2 hours if harness repair needed.
Estimated cost: $450-750 for alternator; $650-1,000 if wiring harness sections require replacement
Transmission Mount Collapse
Common · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Clunking when shifting from Park to Drive or Reverse, Excessive vibration at idle, especially with A/C on, Visible engine/transmission sag when inspected on lift, Harsh engagement into gear
Fix: The lower transmission mount is hydraulic-filled and fails predictably. Replacement requires supporting the transmission and is straightforward but labor-intensive. Plan on 2-3 hours shop time. Inspect all motor mounts while you're in there—they often fail as a set on these.
Estimated cost: $350-550 for transmission mount; $700-1,100 if replacing multiple motor mounts simultaneously
3.6L V6 Rocker Arm and Valve Train Noise
Occasional · medium severityTypical onset: 90,000-140,000 mi
Symptoms: Ticking or tapping noise from engine, especially on cold start, Check engine light with cylinder misfire codes, Loss of power or rough idle, Noise persists after oil change with correct grade
Fix: Pentastar 3.6L can develop rocker arm wear or lifter failure, sometimes traced to oil contamination or extended drain intervals. Requires cylinder head removal to replace rocker arms and inspect cam lobes. Can escalate to full head resurfacing if wear is severe. Budget 8-12 hours labor per head.
Estimated cost: $1,800-2,800 for rocker arms and related valve train parts one head; $3,200-4,800 if both heads require work
Fuel System Clogging and Filter Issues
Occasional · low severityTypical onset: 100,000+ mi
Symptoms: Rough idle or hesitation under acceleration, Check engine light with fuel trim or lean codes, Hard starting after sitting overnight, Intermittent loss of power
Fix: Journey uses an in-tank fuel filter that's not on a regular service interval. Contamination or debris buildup causes running issues. Requires dropping the fuel tank and replacing the fuel pump module assembly. Labor is 3-4 hours.
Estimated cost: $550-850 including pump module and labor
Buy only if dirt cheap and you're handy with a wrench—the 2.4L is a grenade with a timer, and the transmission cooler issue affects all engines. The V6 models are more tolerable but still plagued by the cooling system flaw. Pass unless under $8,000 and you have a Plan B for transportation.
