The 1993 Chrysler Imperial, built on the Y-body platform with the 3.8L V6, is a low-production luxury sedan plagued by transmission failures and expensive engine internal problems. Parts availability is challenging due to limited production numbers.
A604 (41TE) Transmission Failure
Common · high severityTypical onset: 70,000-130,000 mi
Symptoms: Harsh shifts or slipping between gears, especially 2nd to 3rd, Transmission stuck in limp mode (2nd gear only), Delayed engagement when shifting to drive or reverse, Fluid leaks from cooler lines or case seals
Fix: The A604 is notorious for solenoid pack failures, worn clutch packs, and valve body issues. Most shops recommend rebuild or replacement rather than band-aid fixes. Expect 8-12 hours labor for R&R plus rebuild. Cooler line failures can starve the trans of fluid quickly.
Estimated cost: $2,200-3,800
3.8L Engine Internal Failures (Piston/Ring/Bearing)
Occasional · high severityTypical onset: 120,000-180,000 mi
Symptoms: Excessive oil consumption (quart per 500-1000 miles), Blue smoke on startup or acceleration, Knocking or rattling from lower engine, especially cold start, Loss of compression in one or more cylinders
Fix: The 3.8L can develop worn piston rings, scored cylinder walls, or spun bearings, especially if oil changes were neglected. Head gasket failures are also documented. Full rebuild involves 20-30 hours labor; short block replacement is 18-24 hours. Many opt for used engine swaps due to cost.
Estimated cost: $3,500-6,500
ABS System Failures
Common · medium severityTypical onset: 80,000-140,000 mi
Symptoms: ABS warning light illuminated constantly, Pulsing or grinding from ABS pump under hood, Loss of ABS function (conventional brakes still work), Occasional false ABS activation at low speeds
Fix: Bendix 10 ABS system is failure-prone. Pump motor and controller units fail frequently. NHTSA recall addressed some issues but didn't fix systemic problems. Used modules are scarce; remanufactured units run $800-1,200. 3-5 hours labor for pump/controller replacement.
Estimated cost: $1,200-2,000
Transmission Mount Collapse
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Excessive clunking when shifting into drive or reverse, Vibration through floor and steering wheel at idle, Visible engine/trans movement when revving in park, Shifter feels loose or imprecise
Fix: The hydraulic front transmission mount fails regularly, allowing powertrain to sag and shift harshly. Replacement requires lifting powertrain slightly. 2-3 hours labor. Always inspect engine mounts simultaneously as they wear sympathetically.
Estimated cost: $300-500
Fuel System Issues (Filter/Pump/Injectors)
Occasional · medium severityTypical onset: 90,000-150,000 mi
Symptoms: Hard starting, especially when hot, Stumbling or hesitation under acceleration, Stalling at idle or when coming to stops, Check engine light with lean codes or misfire codes
Fix: In-tank fuel pump can fail, and filter clogs if not changed regularly (every 30k recommended). Injectors can clog or leak. Pump replacement requires dropping tank, 3-4 hours. Injector service is 2-3 hours. Many Imperial owners report filter was never changed by previous owners.
Estimated cost: $400-900
Electrical Gremlins (BCM/Instrument Cluster)
Occasional · low severitySymptoms: Intermittent gauge failures (speedometer, fuel, temp), Power accessories working sporadically (windows, locks, seats), Interior lights stuck on or not functioning, No-start due to anti-theft system glitches
Fix: Body Control Module and instrument cluster have cold solder joints and connector corrosion issues. Diagnosis is time-consuming (2-4 hours). Cluster repair or replacement runs $200-600. BCM replacement is rare but expensive ($500-800 parts). Many issues are intermittent and hard to replicate.
Estimated cost: $300-1,200
Cooling System / Head Gasket Leaks
Occasional · medium severityTypical onset: 100,000-160,000 mi
Symptoms: Coolant loss with no visible external leaks, White smoke from exhaust on cold start, Overheating under load or in traffic, Oil appears milky or coolant smells like exhaust
Fix: 3.8L can develop external coolant leaks from intake manifold gaskets or internal leaks from head gaskets. Head gasket job is 12-16 hours labor and requires careful deck surface inspection. Both heads must be done as preventive measure. Intake gaskets alone are 4-6 hours.
Estimated cost: $1,200-2,800
Only buy if you're a Mopar enthusiast with deep pockets and mechanical skills—transmission and engine failures are expensive and common, making this a risky daily driver for the average owner.
