The 1994 Dodge Caravan pioneered the modern minivan but suffers from notorious transmission failures and head gasket issues on certain engines. Budget heavily for drivetrain repairs if buying used.
Automatic Transmission Failure (A604/41TE)
Common · high severityTypical onset: 80,000-140,000 mi
Symptoms: Harsh or delayed shifting between gears, Slipping in 2nd or 3rd gear under load, No movement in drive or reverse, Transmission fluid dark brown or burnt smell
Fix: The 4-speed automatic (A604/41TE) has weak governor pressure solenoids and valve body issues. Rebuild runs 12-16 hours labor; used replacement 6-8 hours. Many need the overdrive planetary and clutch packs replaced. Expect full rebuild or swap.
Estimated cost: $1,800-3,200
3.0L V6 Head Gasket Failure
Common · high severityTypical onset: 90,000-150,000 mi
Symptoms: White smoke from exhaust on cold start, Coolant loss with no visible leaks, Overheating or fluctuating temperature gauge, Milky oil on dipstick or cap
Fix: The Mitsubishi 3.0L V6 blows head gaskets between cylinders or into coolant passages. Both heads should be removed, resurfaced, and new gaskets installed. 14-18 hours labor including coolant flush and timing belt replacement while apart.
Estimated cost: $1,400-2,200
2.5L I4 Bottom End Failure
Occasional · high severityTypical onset: 120,000-180,000 mi
Symptoms: Loud knocking from bottom of engine, Metal shavings in oil, Sudden loss of oil pressure, Engine seizes or won't turn over
Fix: The 2.5L Chrysler four-cylinder grenades connecting rod bearings due to oil starvation or sludge buildup. Needs short block replacement or full engine swap. In-chassis rebuild is 20-26 hours; used engine swap 10-14 hours.
Estimated cost: $2,200-4,000
Transmission Oil Cooler Line Corrosion
Common · medium severityTypical onset: 60,000-120,000 mi
Symptoms: Red fluid dripping near radiator or under van, Transmission running hot or slipping, Low transmission fluid level on dipstick, Rust stains on cooler lines at fittings
Fix: Steel cooler lines rust through at the crimped fittings or along the frame rail. Replace both lines while you're in there; they'll fail within months of each other. 2-3 hours labor plus full fluid and filter service.
Estimated cost: $300-550
Liftgate Latch and Hinge Failure
Occasional · low severitySymptoms: Liftgate won't latch or pops open while driving, Hinge cracks or breaks at mounting points, Liftgate sags on one side, Warning light for open door stays on
Fix: Plastic latch mechanisms wear out and hinges crack from metal fatigue. NHTSA had multiple recalls for these components. Latch replacement is 1 hour; hinge replacement per side is 2-3 hours including realignment.
Estimated cost: $150-600
Engine Mount and Transmission Mount Collapse
Common · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Heavy clunk when shifting into drive or reverse, Engine rocks excessively on acceleration, Vibration at idle in drive, Visible tears in rubber mount material
Fix: Front and rear engine mounts collapse; the front transaxle mount (dogbone) cracks frequently. Replace all three at once to avoid comebacks. 2.5-3.5 hours labor total for all mounts.
Estimated cost: $350-650
EVAP System and Fuel Filter Clogging
Occasional · low severityTypical onset: 80,000-140,000 mi
Symptoms: Check engine light with P0440-P0455 codes, Fuel tank hisses when opening cap, Hesitation or stumbling under acceleration, Hard starting when hot
Fix: Charcoal canister clogs and purge valve sticks; fuel filter (in-line on 2.5L, in-tank on V6s) restricts flow. Canister replacement is 1.5 hours; in-tank fuel filter requires pump removal at 3-4 hours labor.
Estimated cost: $200-550
Only buy if under 100k miles with documented transmission services and the 3.3L V6; otherwise budget $3,000-5,000 for inevitable drivetrain repairs.
