The 2011 Routan is a rebadged Chrysler Town & Country built in Windsor, sharing the RT platform's strengths and fatal flaws—particularly catastrophic engine failures on the 3.8L V6 and persistent transmission cooling issues that can kill the transmission if ignored.
Symptoms: Coolant consumption with no visible leaks, Overheating without warning, Milky oil on dipstick, White smoke from exhaust, Sudden loss of compression on multiple cylinders, Check engine light with misfire codes
Fix: Head gasket failure often cascades into warped heads, scored cylinder walls, and spun bearings due to coolant contamination. Typical repair requires both head gaskets, head resurfacing or replacement, and frequently a full short block if bearings are damaged. Labor alone is 18-24 hours for heads, 28-35 hours for short block replacement. Many owners opt for used engines or scrap the vehicle.
Estimated cost: $4,500-8,500
Transmission Oil Cooler Internal Failure
Common · high severity
Typical onset: 70,000-110,000 mi
Symptoms: Transmission fluid in coolant reservoir (strawberry milkshake appearance), Coolant in transmission pan, Erratic shifting or slipping, Transmission overheating warnings, Engine overheating in some cases
Fix: The cooler inside the radiator fails and cross-contaminates coolant and ATF, destroying the transmission if not caught immediately. Requires radiator replacement, complete transmission fluid flush (often multiple cycles), and frequently a transmission rebuild or replacement if contamination reached clutch packs. Labor is 3-4 hours for cooler/flush if caught early, 12-18 hours if transmission needs rebuild.
Symptoms: Clunking when shifting from Park to Drive or Reverse, Excessive vibration at idle, Visible engine/transmission movement when accelerating, Harsh engagement into gear
Fix: The upper transmission mount deteriorates and allows excessive powertrain movement, accelerating wear on CV axles and other mounts. Replacement requires supporting the transmission and is 2-3 hours labor. Often done alongside lower mount replacement for longevity.
Estimated cost: $350-600
Fuel Filter Clogging and Fuel Pump Module Failure
Occasional · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Hard starting after sitting, Loss of power under acceleration, Stalling at idle or low speed, Check engine light with fuel trim codes, Whining noise from fuel tank area
Fix: In-tank fuel pump module contains filter screen that clogs, starving the engine of fuel. Requires dropping the fuel tank to access. Labor is 2.5-3.5 hours. Often the entire pump module is replaced rather than attempting filter-only service due to age-related pump wear.
Estimated cost: $500-850
Piston Ring Failure Leading to Oil Consumption
Occasional · high severity
Typical onset: 70,000-120,000 mi
Symptoms: Excessive oil consumption (1 quart per 1,000 miles or worse), Blue smoke on startup or acceleration, Fouled spark plugs, Loss of power, Carbon buildup visible in tailpipe
Fix: Piston rings stick or break, allowing oil into combustion chambers. Diagnosis requires compression and leakdown testing. Proper fix is engine disassembly, cylinder honing, new pistons and rings—essentially a rebuild. Labor is 22-30 hours. Many owners drive it with constant oil top-ups until another failure forces the decision.
Estimated cost: $4,000-6,500
Crankshaft Position Sensor Intermittent Failure
Occasional · high severity
Symptoms: No-start condition, especially when engine is hot, Stalling while driving with no warning, Intermittent crank/no-start, Check engine light with P0335 or P0339 codes
Fix: Sensor fails due to heat cycling and leaves you stranded without warning. Common Chrysler V6 issue. Sensor is located behind the starter, making access difficult. Labor is 1.5-2 hours due to tight quarters and need to remove intake components for proper access.
Estimated cost: $250-400
Owner tips
Check radiator/coolant reservoir weekly for milky contamination—catching trans cooler failure early saves thousands
If buying used, pull the dipstick and check for any coolant contamination in oil; walk away if present
On 3.8L engines, any coolant loss without visible leaks is a red flag for head gasket failure—address immediately
Keep detailed oil consumption records; more than 1 quart per 3,000 miles indicates ring problems developing
Replace crankshaft position sensor preventively around 100k miles—cheap insurance against being stranded
Only consider a 3.6L V6 model with verified transmission cooler replacement and documented maintenance—the 3.8L is a ticking time bomb not worth any price.
