The 2019 Grand Caravan rides on Chrysler's ancient RT platform with the proven 3.6L Pentastar V6 and 62TE six-speed automatic. While mechanically similar to 2008-2018 models, oil consumption issues and transmission cooler failures remain chronic weak points that can escalate quickly.
Excessive Oil Consumption / Piston Ring Failure
Common · high severityTypical onset: 60,000-100,000 mi
Symptoms: Low oil warning light between changes, Blue smoke on cold start, Persistent misfire codes (P0300-P0306), Spark plugs fouled with carbon
Fix: 3.6L Pentastar suffers worn piston rings and cylinder scoring. Requires complete engine teardown, new pistons/rings, cylinder honing or boring. Often cheaper to install remanufactured long block. 18-24 labor hours for in-chassis rebuild, 14-16 hours for long block swap.
Estimated cost: $4,500-7,500
Transmission Oil Cooler Line Leak (Internal to Radiator)
Common · high severityTypical onset: 70,000-120,000 mi
Symptoms: Pink milkshake in coolant reservoir (trans fluid mixing with coolant), Transmission slipping or delayed engagement, Overheating transmission, Coolant level dropping with no external leak
Fix: The 62TE transmission cooler integrated into the radiator develops internal leak, cross-contaminating fluids. Requires new radiator, complete transmission fluid flush (often multiple cycles), sometimes new transmission if contamination was severe. 4-6 hours for radiator and flush; add 12-18 hours if transmission damaged.
Estimated cost: $800-1,200 (caught early), $3,500-5,000 (with transmission damage)
Transmission Mount Failure (Front/Rear)
Common · medium severityTypical onset: 80,000-130,000 mi
Symptoms: Harsh clunk when shifting into Drive or Reverse, Vibration at idle in gear, Excessive engine movement visible when accelerating, Rattling over bumps
Fix: Hydraulic transmission mounts collapse internally, allowing driveline to shift excessively. Front mount is most common failure. Requires subframe drop for access on front mount. 2.5-3.5 hours labor.
Estimated cost: $350-550
TIPM Failure (Totally Integrated Power Module)
Occasional · high severitySymptoms: Fuel pump cycling randomly (causes no-start), Wipers running on their own, Power windows/locks operating erratically, Multiple electrical gremlins simultaneously, Stalling at idle after fuel fill-up
Fix: The TIPM (integrated fuse/relay box) develops internal corrosion or solder joint failures. Diagnosis tricky because symptoms are intermittent. Requires TIPM replacement and reprogramming. Some have luck with resoldering fuel pump relay internally (not dealer-supported). 1.5-2 hours for replacement.
Estimated cost: $800-1,400 (new TIPM), $200-400 (DIY resolder/refurbished unit)
Brake Caliper Seizure (Front)
Occasional · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Vehicle pulling to one side during braking, Excessive brake dust on one wheel, Burning smell after driving, Premature brake pad wear on one side, Wheel hot to touch after short drive
Fix: Front brake caliper slide pins seize from corrosion or caliper pistons stick. More common in rust-belt states. Requires caliper replacement, rotor resurfacing/replacement, and brake fluid flush. 2-2.5 hours per side.
Estimated cost: $400-650 per axle
Wheelchair Lift/Tie-Down Failures (Mobility-Equipped Units)
Occasional · medium severitySymptoms: Lift platform will not deploy or retract, Tie-down latches not engaging properly, Electrical faults in mobility equipment, Hydraulic fluid leaks from lift mechanism
Fix: Factory-equipped mobility vans (Braun conversions) suffer from aftermarket component failures. NHTSA recall addressed some latch issues, but hydraulic pump motors and platform mechanisms still fail. Requires specialized mobility equipment dealer—most indie shops won't touch these. 3-8 hours depending on component.
Estimated cost: $600-2,500
Buy only if under 60k miles with documented oil consumption checks and transmission service—budget $2k-3k repair reserve for inevitable cooler/engine issues.
