Common Problems & Known Issues

The 1991 Grand Voyager pioneered Chrysler's front-wheel-drive minivan platform with the 3.3L and 3.8L V6 engines, but shares the Achilles heel of its generation: catastrophic transmission failures and head gasket issues that often total the vehicle economically.

Automatic Transmission Failure (A604/41TE 'Ultradrive')

Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Harsh shifting or slipping between gears, especially 2nd-3rd, Delayed engagement when shifting from park to drive, Transmission goes into limp mode (stuck in 2nd gear), Whining or grinding noises during acceleration, Complete loss of forward gears
Fix: The A604 Ultradrive transmission is notoriously fragile with solenoid pack and clutch failures. Transmission cooler blockage accelerates failure. Rebuild requires 12-16 hours labor; remanufactured units are often more cost-effective. External cooler addition recommended during any rebuild.
Estimated cost: $1,800-3,200

Head Gasket Failure (3.3L V6)

Common · high severity
Typical onset: 90,000-150,000 mi
Symptoms: White smoke from exhaust on cold starts, Coolant loss with no visible leaks, Milky oil on dipstick or under oil cap, Overheating under load, Rough idle and misfires
Fix: The 3.3L is prone to head gasket failure between cylinders and into coolant passages. Often warps heads requiring machining. Requires 14-18 hours labor for both heads. At this mileage, also replace timing chain, water pump, and all seals. Many engines are scrapped rather than repaired.
Estimated cost: $2,200-3,800

Liftgate Hinge and Latch Failure

Common · medium severity
Symptoms: Liftgate won't stay open or falls unexpectedly (dangerous), Latch won't engage or hold closed while driving, Metal fatigue cracks visible around hinge mounting points, Rattling from rear during driving
Fix: The liftgate hinges crack and struts wear out, while latches strip internally. Both were subject to recalls but corrosion and age cause failures even on repaired units. Hinge replacement requires 3-4 hours and may need body panel reinforcement. Latch is 1.5 hours.
Estimated cost: $350-750

Front Engine Mount and Transmission Mount Failure

Common · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: Severe vibration at idle in gear, Clunking when shifting from park to drive/reverse, Engine visibly moves or rocks excessively, Vibration increases with AC compressor engagement
Fix: Hydraulic engine mounts collapse internally and transmission mounts tear from torque stress. Front mount is 2 hours, transmission mount is 1.5 hours but requires trans support. Replace all three main mounts together to prevent domino failures.
Estimated cost: $400-650

Windshield Wiper Linkage Bushing Failure

Occasional · medium severity
Typical onset: 80,000-140,000 mi
Symptoms: Wipers stop moving or only one wiper works, Wipers move erratically or out of sync, Clicking or popping noise from cowl area when wipers run, Wipers park in wrong position
Fix: Plastic bushings in the wiper linkage dry out and disintegrate, causing the linkage arms to separate. Was subject to recall but affects most high-mileage examples. Requires 2-3 hours to remove cowl and replace entire linkage assembly.
Estimated cost: $250-450

3.8L V6 Lower Engine Failure (Piston/Bearing)

Occasional · high severity
Typical onset: 120,000-180,000 mi
Symptoms: Knocking noise from bottom of engine, especially when cold, Metal shavings in oil during oil changes, Low oil pressure warning at idle, Sudden catastrophic failure with rod through block
Fix: The 3.8L develops rod bearing and piston skirt wear from inadequate oil changes and design limitations. Once knocking starts, failure is imminent. Requires complete short block replacement or engine swap. 18-24 hours labor. Most owners junkyard the vehicle at this point.
Estimated cost: $3,500-5,500

Steering Column Lock Mechanism and Coupler Wear

Occasional · medium severity
Typical onset: 100,000+ mi
Symptoms: Ignition key difficult to turn or won't release from lock, Clunking felt through steering wheel on turns, Steering wheel off-center after turns, Play in steering wheel at center position
Fix: Steering column lock cylinder wears and the rubber steering coupler deteriorates, causing play. Column work requires airbag removal and disassembly. Lock cylinder is 2 hours, coupler replacement is 1.5 hours. Both often needed together on high-mileage examples.
Estimated cost: $300-600
Owner tips
  • Change transmission fluid every 30,000 miles religiously with Mopar-spec ATF+4 — this extends A604 life significantly
  • Install auxiliary transmission cooler immediately if towing or in hot climates
  • Monitor coolant level weekly — head gasket failures start subtly
  • Replace engine mounts at first sign of vibration to prevent transmission mount damage
  • Flush cooling system every 2 years — the 3.3L runs hot and corrosion accelerates head gasket failure
Only buy if transmission has been recently rebuilt with cooler upgrade and engine has documented head gasket replacement — otherwise you're buying someone else's $3,000+ repair bill waiting to happen.
