The 2021 Chrysler Voyager is essentially a rebadged Pacifica with the proven 3.6L Pentastar V6 and 9-speed automatic. While newer than typical problem vehicles, early adopters are seeing premature transmission failures and catastrophic engine issues that suggest quality control gaps in certain production runs.
9-Speed Automatic Transmission Failure (Oil Cooler Leak Leading to Internal Damage)
Occasional · high severityTypical onset: 40,000-80,000 mi
Symptoms: Transmission fluid leaking from oil cooler area onto subframe, Harsh shifts, delayed engagement, or slipping between gears, Check engine light with codes P0868 (transmission fluid pressure low) or P0730 (incorrect gear ratio), Burnt transmission fluid smell or dark/metallic fluid on dipstick
Fix: Transmission oil cooler replacement is 3-4 hours if caught early. If internal damage occurred from running low on fluid, you're looking at transmission rebuild (12-16 hours) or replacement with remanufactured unit (8-10 hours). Many shops recommend replacing cooler proactively during routine service at 60k if no extended warranty.
Estimated cost: $800-1,200 cooler only; $3,500-5,500 rebuild; $4,000-6,000 reman replacement
Catastrophic Engine Failure (Piston/Bearing/Ring Issues)
Rare · high severityTypical onset: 30,000-70,000 mi
Symptoms: Sudden knocking or rattling from engine bay, especially on cold start, Metal shavings in oil during changes, Check engine light with misfire codes (P0300-P0306) or low oil pressure warning, Excessive oil consumption (more than 1 quart per 1,000 miles), Complete engine seizure in worst cases
Fix: This is a full engine rebuild or replacement scenario. Short block replacement runs 18-24 hours; full rebuild with heads 25-30 hours. Some failures traced to defective piston rings causing cylinder scoring, others to bearing failures from oil system issues. Chrysler has been hit-or-miss on warranty coverage even within powertrain warranty period—document everything.
Estimated cost: $6,500-9,000 short block; $8,000-12,000 complete rebuild
Broken Transmission Motor Mount
Common · medium severityTypical onset: 50,000-90,000 mi
Symptoms: Clunking noise when shifting from park to drive or reverse, Excessive engine movement visible when accelerating/decelerating, Vibration through cabin at idle or under load, Hesitation or delay when throttle applied from stop
Fix: The hydraulic transmission mount fails prematurely on these minivans, likely due to weight and torque characteristics. Replacement is straightforward: 1.5-2 hours to swap mount. Use OEM or quality aftermarket (Mopar or equivalent)—cheap parts fail within 20k miles.
Estimated cost: $250-450
Power Sliding Door Latch Failures
Occasional · low severitySymptoms: Door won't latch or open electronically, but manual override works, Warning chime indicating door ajar when fully closed, Door begins to open then reverses/stops mid-cycle, Clicking or grinding noise from latch mechanism
Fix: The power latch actuators wear out or get contaminated with dirt/debris. Each latch assembly is 2-2.5 hours to replace (door panel removal, actuator swap, recalibration). Both sides often fail within 10k miles of each other, so some owners opt to do both preventively. TSBs exist but no official recall yet.
Estimated cost: $400-650 per side
Fuel Filter Clogging (Premature)
Occasional · medium severityTypical onset: 60,000-90,000 mi
Symptoms: Rough idle or stalling, especially after refueling, Loss of power during acceleration or highway merging, Check engine light with fuel trim or lean condition codes (P0171/P0174), Hard starting after sitting overnight
Fix: The in-tank fuel filter/pump module sees premature clogging in some units, possibly from manufacturing debris or poor fuel quality. Replacement requires dropping the tank (2.5-3.5 hours). Use OEM Mopar module—aftermarket pumps have higher failure rates on these.
Estimated cost: $600-900
NHTSA Recall: Curtain Airbag Fabric Detachment
Common · high severitySymptoms: No symptoms until deployment needed—preventive recall, In affected vehicles, curtain airbag fabric can separate from module during deployment, Reduces side-impact head protection effectiveness
Fix: Factory recall requiring both side curtain airbag replacements. Dealer-only repair, 3-4 hours total. Check VIN at NHTSA.gov—many 2021s affected. No cost to owner, but schedule ASAP as parts have been backordered.
Estimated cost: $0 (warranty recall)
Buy only with bumper-to-bumper warranty remaining or budget $3-5k for potential major repairs; the transmission and engine issues are too severe to gamble on out-of-warranty.
