The 2004 Acura TL is a solid luxury sedan with Honda's 3.2L J32A3 V6, but it's plagued by catastrophic automatic transmission failures and a well-documented engine block porosity defect that can grenade motors without warning.
Automatic Transmission Failure (BYBA/BGFA Units)
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Harsh or delayed 2-3 shift, flare on 3-4 upshift, Shuddering during acceleration or lockup, Check engine light with P0730, P0740, P1738 codes, Burning smell or dark/metallic transmission fluid, Complete loss of forward gears (third clutch pack failure)
Fix: Requires full transmission rebuild or replacement. The third clutch pack and its pressure switch are the weak links. Rebuild takes 10-14 hours; remanufactured unit swap is 8-10 hours. Many shops won't rebuild these anymore due to high re-failure rates.
Estimated cost: $2,800-4,500
Engine Block Porosity / Premature Engine Failure
Occasional · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Rapid coolant loss with no visible external leaks, White smoke from exhaust on cold start, Milky oil on dipstick or oil cap, Overheating with no apparent cause, Catastrophic bearing failure due to coolant contamination
Fix: Factory defect where cylinder walls become porous, allowing coolant into combustion chambers and oil galleys. Only fix is engine replacement or complete short-block rebuild. Short block R&R is 18-24 hours; used JDM motors are common solution at 12-16 hours swap time.
Estimated cost: $3,500-6,000
Lower Ball Joint Separation (Recall 08V-577)
Common · high severity
Typical onset: 70,000-130,000 mi
Symptoms: Clunking over bumps from front suspension, Steering wander or looseness, Uneven inner tire wear, Front end wobble at highway speeds, Complete wheel separation in worst cases (NHTSA recall item)
Fix: Factory ball joint stud can crack and separate. Acura issued recall but many units still in service were never fixed. Control arms are replaced as assemblies (ball joints not serviceable separately). 2.5-3.5 hours per side for both lower arms.
Estimated cost: $800-1,200
Power Steering Hose Leaks
Common · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Power steering fluid puddles under car (driver side), Groaning or whining when turning at low speeds, Difficulty turning wheel when cold, Burning smell from fluid hitting exhaust manifold
Fix: High-pressure hose from pump to rack deteriorates, often at crimp points. Hose runs along engine block and gets heat-cycled to death. Was subject to recall 09V-071 but only certain VINs. Replace both feed and return lines while you're in there. 2-3 hours labor.
Estimated cost: $400-700
Transmission Oil Cooler Line Leaks
Common · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: Red fluid dripping from radiator area, Low transmission fluid warnings or slipping, Transmission overheating after highway driving, Pink residue visible on radiator tank or cooler lines
Fix: Rubber cooler lines crack where they connect to hard lines at the radiator. Can also get cross-contamination if internal cooler fails (coolant in trans fluid or vice versa). External lines are 1.5-2 hours; if radiator internal cooler failed, both radiator and trans need service (4-6 hours total plus fluid flushes).
Estimated cost: $300-500
Rear Differential Mount Failure
Occasional · low severity
Typical onset: 100,000-150,000 mi
Symptoms: Clunk when shifting from park to drive or reverse, Vibration under acceleration (feels like driveline), Visible oil seepage around differential (mount stress cracks seals), Exhaust rattle on deceleration
Fix: Rear differential mount deteriorates, allowing excessive movement. This can stress diff seals and cause leaks. Mount replacement is 2-3 hours (need to support subframe). Often done with transmission mount as preventive measure.
Estimated cost: $400-650
Evaporative Emissions Canister / Fuel System Issues
Occasional · low severity
Symptoms: P0441, P1456, or P1457 EVAP codes, Difficulty filling gas tank (pump clicks off repeatedly), Strong fuel smell near rear of vehicle, Check engine light after refueling
Fix: EVAP canister saturates with liquid fuel if tank is overfilled repeatedly, or vent valve sticks. Canister lives under car near fuel tank. Diagnosis takes 1-2 hours with smoke test; canister replacement is 1.5 hours, but often need purge valve and vent valve too.
Estimated cost: $350-750
Owner tips
Change transmission fluid every 30,000 miles with Honda DW-1 (NOT generic ATF) — won't prevent failure but may delay it
Watch coolant level religiously; if you're adding more than a cup every few months with no visible leaks, start budgeting for an engine
Have ball joints inspected annually after 60k miles — the recall didn't catch all affected units
Keep power steering reservoir topped off; pump failure from running dry will cost you $800+ and it happens fast
Buy only if transmission has already been replaced and you have proof of regular fluid changes; budget $3,000-5,000 for deferred powertrain issues on any high-mileage example.
