Common Problems & Known Issues

The 2005 Acura RL is a front-wheel-drive luxury sedan with Honda's 3.5L V6 and a 5-speed automatic. While refined and well-equipped, this generation suffers from catastrophic transmission failures and premature engine bearing wear that can grenade an otherwise solid platform.

Transmission Self-Destruction (5-Speed Automatic)

Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Harsh or delayed shifts, especially 2-3 and 3-4, Shuddering on acceleration or under light load, Metallic debris in transmission fluid during service, Complete loss of drive with internal clutch pack failure
Fix: Honda's 5-speed auto in this chassis has weak clutch packs and inadequate cooling. Rebuilds rarely last; remanufactured unit is the only reliable fix. 8-12 hours labor for R&R, plus unit cost.
Estimated cost: $3,500-5,500

Engine Bearing Failure (Connecting Rod and Main Bearings)

Occasional · high severity
Typical onset: 100,000-180,000 mi
Symptoms: Knocking or ticking noise from lower engine block, worsens with RPM, Low oil pressure warning or fluctuating pressure at idle, Metallic flakes or glitter in oil during changes, Catastrophic failure: thrown rod through block
Fix: The J35A8 engine in the RL has known issues with bearing clearances and oiling under sustained load. Repair requires full teardown, new bearings, honing, and sometimes crank machining. Most shops recommend a short block or used engine instead. 18-24 hours labor for engine R&R and rebuild.
Estimated cost: $4,500-7,500

Takata Airbag Inflator Rupture Risk

Common · high severity
Symptoms: NHTSA recall notices (multiple campaigns for driver and passenger inflators), No symptoms until deployment, when inflator can explode and send shrapnel into cabin
Fix: Critical safety recall. Acura replaces inflators at no cost, but parts have been on backorder for years in some regions. Verify recall completion before purchase. 1-2 hours labor per side when parts available.
Estimated cost: $0 (manufacturer recall)

Power Steering Hose Leaks and Pump Failure

Common · medium severity
Typical onset: 90,000-150,000 mi
Symptoms: Power steering fluid puddles under front of vehicle, Whining or groaning noise when turning at low speed, Stiff steering, especially when cold, Low fluid warning or burning smell from leaked fluid on exhaust
Fix: High-pressure hoses crack and weep at crimp fittings; pump seals fail from heat cycling. NHTSA recall covers some hose failures. Replace both hoses and pump as a set for longevity. 2-3 hours labor.
Estimated cost: $600-1,200

Transmission Cooler Line Corrosion and Leaks

Common · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: Red transmission fluid dripping from front of engine bay or undercarriage, Low transmission fluid warning or slipping shifts, Visible rust or green corrosion on steel cooler lines near radiator
Fix: Factory steel lines rust through where they pass near the subframe and under the engine. Leaking trans fluid starves an already-marginal transmission. Replace with OEM aluminum lines or aftermarket stainless. 2-4 hours labor depending on accessibility.
Estimated cost: $400-800

Head Gasket Seepage (Coolant and Oil Mixing)

Occasional · high severity
Typical onset: 120,000-180,000 mi
Symptoms: White smoke from exhaust on cold start, Milky or frothy oil on dipstick or under oil cap, Persistent overheating or coolant loss with no external leaks, Rough idle or misfires in cylinders 1, 2, or 3
Fix: J35 head gaskets can fail between cylinders and coolant passages, or externally at rear corners. Requires heads off, resurfacing, new gaskets, timing belt, and water pump while in there. 14-18 hours labor.
Estimated cost: $2,800-4,200

ABS Modulator Failure (Pump Motor and Solenoids)

Occasional · medium severity
Typical onset: 100,000-160,000 mi
Symptoms: ABS and VSA warning lights on dash, Grinding or buzzing noise from ABS unit under hood (left front), Loss of ABS function; brakes work but no anti-lock assist, Occasional false ABS activation on dry pavement
Fix: Honda ABS modulators from this era have motor brush wear and solenoid coil failures. Rebuild services exist, but remanufactured unit is more reliable. NHTSA recall covered some units for free. 2-3 hours labor plus bleeding.
Estimated cost: $1,200-2,200
Owner tips
  • Change transmission fluid every 30,000 miles with Honda DW-1 ATF only — this trans runs hot and fluid degrades fast
  • Use 5W-20 synthetic oil and change every 5,000 miles; bearing wear is accelerated by extended drain intervals
  • Check transmission cooler lines and power steering hoses annually for weeping or corrosion
  • Verify Takata airbag recall completion before purchase — this is a life-safety issue
  • Budget for a transmission replacement if buying over 100k miles; it's when, not if
Avoid unless transmission and engine have verifiable recent replacements and all recalls are done — the drivetrain time bombs outweigh the RL's otherwise solid luxury-sedan qualities.
