The 2013 Acura TL is a solid luxury sedan, but the 3.7L V6 with the 6-speed automatic faces a critical transmission failure issue that can ruin your day and your wallet. The 3.5L models are generally more reliable, though both engines share some aging platform quirks.
Automatic Transmission Failure (3.7L models primarily)
Common · high severityTypical onset: 80,000-130,000 mi
Symptoms: Harsh shifting between 2nd and 3rd gear, especially when cold, Flare or slipping during upshifts under moderate acceleration, Transmission shudder at highway speeds around 45-55 mph, Check engine light with P0730 (incorrect gear ratio) or P0730-series codes
Fix: The 6-speed automatic in 3.7L TLs has weak 2nd and 3rd gear clutch packs that burn out prematurely. Trans oil cooler can also fail internally and contaminate the fluid, accelerating failure. Rebuild requires 12-16 hours; most shops recommend replacement with remanufactured unit. Always replace the trans cooler simultaneously or you'll be back in six months.
Estimated cost: $3,500-5,500
VCM (Variable Cylinder Management) Fouling Issues
Occasional · medium severityTypical onset: 90,000-150,000 mi
Symptoms: Excessive oil consumption (1 quart per 1,000 miles or worse), Rough idle with vibration when VCM activates (3-cylinder mode), Fouled spark plugs on cylinders 1, 4, and 6, P0300-series misfire codes, often multiple cylinders
Fix: Honda's VCM system causes oil control ring coking on the deactivating cylinders. Leads to oil burning and eventually piston ring failure if ignored. Proper fix involves top-end teardown, piston ring replacement, and often valve cleaning—20-28 hours labor. Many owners install VCM defeat devices ($300-500) to prevent recurrence, though this slightly hurts fuel economy. If caught early, walnut blasting the intake valves and running higher-detergent oil can extend life.
Estimated cost: $3,800-6,000
Transmission Mount Collapse
Common · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Clunk when shifting from Park to Drive or Reverse, Excessive vibration at idle, especially with A/C on, Visible engine sag when viewing from side with hood open, Harsh engagement during gear changes
Fix: The upper transmission mount (engine side) uses a fluid-filled design that fails predictably. The front engine mount often goes at similar mileage. Replace both simultaneously—2.5-3.5 hours. Access is decent from the top. OEM mounts are worth the premium over aftermarket.
Estimated cost: $450-750
Power Steering Pump Whine and Failure
Occasional · medium severityTypical onset: 100,000-140,000 mi
Symptoms: High-pitched whine from engine bay, worse during cold starts, Whining increases with steering input at low speeds, Intermittent stiff steering, especially when first starting out, Power steering fluid level drops without visible leaks
Fix: The hydraulic power steering pump develops internal wear, and the high-pressure line o-rings leak. Pump replacement is 2-3 hours; simultaneously inspect pressure and return lines. Flushing the system with genuine Honda PSF prevents premature wear of the replacement. Some pumps fail catastrophically and dump fluid rapidly.
Estimated cost: $600-950
Front Lower Control Arm Bushings
Common · low severityTypical onset: 80,000-120,000 mi
Symptoms: Clunking over bumps from front suspension, Steering feels vague or wanders slightly on highway, Inner edge tire wear on front tires, Alignment won't hold after fresh adjustment
Fix: The front lower control arm rear bushings tear and cause alignment drift. Honda sells the arms as complete assemblies only (no bushing service parts). Both sides typically need replacement—3-4 hours with alignment. Aftermarket arms exist but OEM fit and durability are superior.
Estimated cost: $800-1,200
Takata Airbag Inflator Recall (All 2013 TLs)
Common · high severitySymptoms: Recall notice from Acura (check VIN at NHTSA site), No symptoms until airbag deploys—then metal shrapnel risk, SRS light may illuminate if inflator internal corrosion advances
Fix: All 2013 TLs are subject to the Takata driver airbag inflator recall. The inflator can rupture violently during deployment, sending metal fragments into the cabin—multiple fatalities documented across Honda/Acura lineup. Repair is free at any Acura dealer, takes 1-2 hours. DO NOT skip this—it's legitimately life-threatening. Check recall status before purchasing any used TL.
Estimated cost: $0
Buy a 3.5L model with documented trans fluid changes, or budget $4k for eventual transmission work on a 3.7L—otherwise a comfortable, well-built sedan that can go 200k+ with care.
