The 2012 Routan is a rebadged Chrysler Town & Country with VW badges, sharing all Chrysler platform issues. Transmission cooler failures and catastrophic engine problems dominate the high-mileage complaint list, making this one of the riskier minivan choices.
Transmission Oil Cooler Failure Leading to Transmission Contamination
Common · high severityTypical onset: 70,000-120,000 mi
Symptoms: Pink milkshake appearance in coolant overflow tank (transmission fluid mixing with coolant), Transmission slipping or delayed engagement after cooler failure, Overheating transmission followed by complete failure, Check engine light with transmission codes
Fix: Replace transmission oil cooler and flush both cooling system and transmission. If coolant entered transmission, full rebuild or replacement required. Preventive cooler replacement: 3-4 hours labor. Post-failure with transmission damage: 12-18 hours for rebuild or R&R.
Estimated cost: $800-1,200 preventive cooler replacement; $3,500-5,500 with transmission rebuild
3.6L Pentastar Engine Cylinder Head Gasket Failure
Occasional · high severityTypical onset: 80,000-140,000 mi
Symptoms: External coolant leaks from cylinder head seam, often driver side, Overheating under load or in hot weather, White smoke from exhaust if internal breach, Coolant loss with no visible external leak, Misfires on specific cylinders
Fix: Both cylinder heads typically done together due to labor overlap. Requires complete top-end disassembly. 16-20 hours labor. Machine work if heads are warped adds cost and time.
Estimated cost: $3,200-5,000
Rocker Arm and Valve Train Failure (3.6L)
Occasional · high severityTypical onset: 60,000-110,000 mi
Symptoms: Loud ticking or tapping noise from engine, often one side, Check engine light with multiple misfire codes, Metal shavings in oil during changes, Sudden catastrophic loss of power, Engine may need full rebuild if metal circulated
Fix: Failed rocker arms drop valves or fragments circulate through engine. If caught early, cylinder head removal and rocker/lifter replacement runs 14-18 hours. Often leads to short block replacement if damage is extensive.
Estimated cost: $2,800-4,500 if caught early; $6,000-9,000 for short block replacement
Transmission Mounts Collapsing
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Severe clunking when shifting from park to drive or reverse, Visible engine/transmission movement when accelerating or braking, Vibration at idle in gear, Transmission shifter feels loose or notchy
Fix: Front and rear transmission mounts both prone to failure. Replace both at same time. 2-3 hours labor total.
Estimated cost: $400-700
Fuel Pump and Fuel Filter Clogging Issues
Occasional · medium severityTypical onset: 90,000-150,000 mi
Symptoms: Hard starting, especially when hot, Stalling or hesitation under acceleration, Loss of power going uphill or under load, Fuel pump whining noise from rear of vehicle
Fix: Fuel pump is in-tank assembly. Filter is integral to pump on most years. Tank must be dropped. 3-4 hours labor.
Estimated cost: $650-1,100
Power Sliding Door Motor and Track Failures
Common · low severityTypical onset: 50,000-120,000 mi
Symptoms: Door opens or closes partially then reverses or stops, Grinding or clicking noise during operation, Door will not latch properly, Error messages on dash about door system
Fix: Motors, cables, and tracks all wear. Diagnosis requires checking each component. Motor replacement: 2-3 hours per side. Cable/track cleaning and adjustment: 1-2 hours.
Estimated cost: $500-1,200 per door depending on component
TIPM (Totally Integrated Power Module) Failures
Occasional · high severitySymptoms: Random electrical gremlins (wipers, windows, locks operating on their own), Fuel pump not priming, no-start condition, Gauges going haywire or shutting off, Multiple warning lights illuminated, Intermittent issues that come and go
Fix: Known Chrysler platform issue. TIPM is the central relay/fuse box under hood. Replacement requires programming. 2-3 hours labor. Some shops offer TIPM repair services for less than new unit.
Estimated cost: $800-1,500 for replacement; $300-600 for repair service
Hard pass unless you're getting it dirt cheap with full service records showing preventive transmission cooler replacement — the Chrysler powertrain issues make this one of the least reliable minivans you can buy used.
