The 2014 Grand Caravan with the 3.6L Pentastar V6 is generally solid mechanically, but the 62TE transmission and its cooling system are weak points that can cost thousands if neglected. Engine failures happen but are less common than transmission issues.
Transmission Oil Cooler Failure (Internal Radiator Leak)
Common · high severityTypical onset: 80,000-150,000 mi
Symptoms: Transmission fluid in coolant or coolant in transmission (strawberry milkshake appearance), Transmission slipping, delayed engagement, or complete failure, Engine overheating or transmission overheating warnings, Pink residue in coolant overflow tank
Fix: Replace radiator (has integrated trans cooler), flush both cooling and transmission systems thoroughly, often requires transmission rebuild or replacement if contamination went unnoticed. 8-12 hours labor if trans is salvageable, 15-20+ if rebuild needed.
Estimated cost: $1,200-$5,500
62TE Transmission Solenoid Pack and Valve Body Issues
Common · high severityTypical onset: 70,000-120,000 mi
Symptoms: Harsh or delayed shifts, especially 2nd to 3rd gear, Transmission stuck in 2nd or 3rd gear (limp mode), Check engine light with codes P0750, P0868, P0871 (solenoid/pressure codes), Banging or clunking on downshifts
Fix: Drop pan, replace solenoid pack and often the valve body, fresh fluid and filter. Some techs try solenoid-only first (4-5 hours), but valve body replacement is more thorough (6-8 hours). Sometimes full rebuild is necessary if internal clutches are damaged.
Estimated cost: $1,500-$3,800
Transmission Mount Failure (Upper and Lower)
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Clunking or thudding when shifting from park to drive or reverse, Excessive engine/trans movement visible when accelerating, Vibration felt through floorboard at idle in gear, Difficulty shifting smoothly
Fix: Replace upper and lower transmission mounts, sometimes dogbone mount too. Upper mount requires supporting the engine/trans; lower mount is easier. 2-3 hours total for both.
Estimated cost: $400-$700
3.6L Pentastar Left Cylinder Head Failure (Valvetrain)
Occasional · high severityTypical onset: 100,000-150,000 mi
Symptoms: Cylinder misfire codes (typically left bank: cylinders 1, 3, 5), Ticking or tapping noise from left side of engine, Loss of power, rough idle, Metal shavings in oil or low oil pressure if rocker arm fails
Fix: Left head removal, replace rocker arms, lifters, and resurface or replace head. Sometimes requires full head gasket set for both sides preventively. 12-16 hours labor. If caught late with bearing damage, short block or full engine replacement needed (20-30 hours).
Estimated cost: $3,000-$8,500
TIPM (Totally Integrated Power Module) Electrical Gremlins
Occasional · medium severitySymptoms: Intermittent no-start or crank/no-start conditions, Fuel pump not priming, Power windows, wipers, or other accessories working intermittently, Warning lights randomly illuminating
Fix: Diagnose with scan tool to confirm TIPM fault (not always obvious). Replacement TIPM requires programming to VIN. Some independent fixes involve reflowing solder joints inside module. 2-3 hours for replacement and programming.
Estimated cost: $800-$1,400
Windshield Wiper Motor Linkage Bushing Failure
Common · low severityTypical onset: 80,000-120,000 mi
Symptoms: Wipers moving slowly or binding, One wiper not moving or moving erratically, Clicking or grinding noise from wiper motor area, Wipers work intermittently
Fix: Replace wiper motor linkage assembly or just the plastic bushings if available separately. Motor cowl removal required. 1.5-2.5 hours.
Estimated cost: $250-$500
Reliable kid-hauler if you're vigilant about the transmission and its cooling system; budget $2K-3K for eventual trans work and you'll likely get 200K+ miles.
