The 1997 Acura RL is Honda's flagship sedan with a smooth C32A 3.5L V6, but it's plagued by catastrophic automatic transmission failures and serious engine internal issues—both expensive enough to total an otherwise nice car.
Automatic Transmission Failure (Complete Internal Breakdown)
Common · high severityTypical onset: 80,000-140,000 mi
Symptoms: Harsh shifting or slipping between gears, especially 2nd-3rd, Transmission shuddering during acceleration, Metal shavings in fluid during service, Complete loss of forward gears, stuck in limp mode
Fix: The 4-speed automatic in the RL is notoriously weak for this chassis weight. Internal clutch packs and bands wear prematurely. Rebuild requires 12-16 hours labor, but most shops recommend replacement with a remanufactured unit due to poor rebuild longevity. Includes R&R, fluid, filter, and cooler inspection.
Estimated cost: $3,200-5,500
Engine Internal Failure (Piston Ring Land Collapse, Rod Bearing Wear)
Occasional · high severityTypical onset: 120,000-180,000 mi
Symptoms: Excessive oil consumption (1 qt per 500-800 miles), Blue smoke on startup or acceleration, Knocking or ticking noise from lower engine, worse when warm, Low oil pressure warning intermittently
Fix: The C32A has weak piston ring lands that crack under heat stress, and rod bearings that fail if oil changes were stretched. Requires complete engine teardown—head gasket replacement runs 14-18 hours, full rebuild with pistons/rings/bearings is 24-32 hours. Many owners opt for used low-mileage JDM engine swap instead (12-16 hours labor).
Estimated cost: $4,500-8,000
Transmission Oil Cooler Line Corrosion and Leaks
Common · medium severityTypical onset: 90,000-150,000 mi
Symptoms: ATF puddles under front of vehicle, Low transmission fluid level without visible external leaks elsewhere, Transmission overheating warning (if equipped), Rusty staining on radiator support area
Fix: Steel cooler lines rust through where they contact the subframe and route near the radiator. Replacement requires removing splash shields and sometimes the radiator for access. 2.5-4 hours labor plus lines, fittings, and 4 qts ATF.
Estimated cost: $450-750
Lower Ball Joint Separation (NHTSA Recall Item, Often Incomplete)
Occasional · high severityTypical onset: 70,000-130,000 mi
Symptoms: Clunking from front suspension over bumps, Steering wander or pulling to one side, Visible grease boot torn or missing on lower ball joint, Excessive play during suspension inspection
Fix: There was a recall for lower ball joint separation, but many vehicles were never serviced or the fix didn't hold long-term. Requires replacement of entire lower control arm assembly per side. 2-3 hours labor per side, includes alignment.
Estimated cost: $600-900
Fuel Filter Clogging (In-Tank Design)
Common · medium severityTypical onset: 100,000+ mi
Symptoms: Hesitation or stumbling during acceleration, Hard starting after sitting overnight, Loss of power at highway speeds, Check engine light with lean codes (P0171/P0174)
Fix: The RL uses an in-tank fuel filter that clogs from sediment and ethanol deposits. Requires fuel tank drop for access. 3-4 hours labor plus filter and fuel pump strainer replacement recommended simultaneously.
Estimated cost: $550-850
Transmission Mount Collapse
Common · low severityTypical onset: 80,000-120,000 mi
Symptoms: Clunk or thud when shifting from Park to Drive, Excessive engine movement visible from engine bay during acceleration, Vibration at idle in Drive with brake applied, Slight binding feeling in shifter operation
Fix: Hydraulic transmission mount fails internally, allowing excessive drivetrain movement. Replacement is straightforward but requires supporting the transmission. 1.5-2 hours labor.
Estimated cost: $280-450
Only buy if under 80k miles with immaculate service records and a pre-purchase compression test; otherwise, the transmission and engine time bombs make this a $2,000 car no matter how clean it looks.
