Common Problems & Known Issues

The 2014 Acura TSX is Honda's upscale midsize sedan with generally solid reliability, but the automatic transmission and certain V6 engine variants have well-documented issues that can be expensive. The 2.4L I4 is more dependable overall, though both suffer from a few common annoyances.

Automatic Transmission Judder and Premature Failure

Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: harsh or delayed shifts between 2nd and 3rd gear, shuddering or vibration during light acceleration, slipping under load, Check Engine light with transmission codes P0730/P0741
Fix: Transmission fluid and filter changes may help early on (2 hours labor), but most cases need torque converter replacement (8-10 hours) or full transmission rebuild/replacement (12-16 hours). The transmission oil cooler often fails simultaneously and should be replaced during any major trans work.
Estimated cost: $3,500-6,500

V6 Engine Excessive Oil Consumption and Piston Ring Failure

Occasional · high severity
Typical onset: 80,000-150,000 mi
Symptoms: burning through 1+ quart of oil every 1,000 miles, blue smoke from exhaust on cold start or acceleration, fouled spark plugs, loss of power and misfires
Fix: This J35 V6 variant has known piston ring and cylinder bore issues. Short-term: frequent oil top-ups and plug changes. Long-term requires engine rebuild with new pistons, rings, and possibly cylinder honing (25-35 hours labor) or used engine swap (18-22 hours).
Estimated cost: $4,500-7,500

Transmission Mount Failure

Common · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: clunking noise when shifting from Park to Drive or Reverse, excessive engine movement visible when accelerating, vibration at idle that changes when shifting to Drive
Fix: The upper transmission mount (often called the torque mount) deteriorates and separates. Replacement is straightforward: 1.5-2 hours labor. Should be done with OEM or high-quality aftermarket parts—cheap mounts fail quickly.
Estimated cost: $250-450

Takata Airbag Inflator Recall Issues

Common · high severity
Symptoms: recall notice from Acura, no symptoms until deployment—then risk of metal shrapnel injury
Fix: This is a safety recall with free dealer replacement. However, many 2014 TSX owners still haven't completed the fix due to parts shortages in previous years. Verify recall completion before purchase—takes 1-2 hours at dealer, no cost to owner.
Estimated cost: $0

Power Steering Pump Whine and Failure

Occasional · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: whining or groaning noise when turning, especially when cold, intermittent heavy steering, fluid leaks near pump or rack
Fix: The hydraulic power steering pump develops internal wear. Fluid flush (1 hour) may quiet it temporarily, but replacement pump is the real fix (2-3 hours labor). Also inspect high-pressure hose for leaks during replacement.
Estimated cost: $600-1,100

VTC Actuator Rattle on Cold Start (I4 Engine)

Occasional · low severity
Typical onset: 100,000+ mi
Symptoms: loud rattle or chattering for 1-2 seconds on cold start, noise goes away once oil pressure builds, no Check Engine light or performance issues
Fix: The Variable Timing Control (VTC) actuator on the 2.4L I4 wears internally. Using Honda/Acura 0W-20 oil and changing it on time helps delay this. Replacement requires removing valve cover and timing chain components (4-5 hours labor). Mostly a noise annoyance—not urgent unless it persists warm.
Estimated cost: $700-1,200

Fuel Injector Clogging and Misfire (V6)

Occasional · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: rough idle and hesitation, Check Engine light with misfire codes P0300-P0306, poor fuel economy
Fix: Direct injection on the V6 leads to carbon buildup and injector issues. Professional injector cleaning or walnut-blasting intake valves (3-4 hours) often helps. Failed injectors must be replaced individually (1.5 hours each). Use Top Tier gas and occasional fuel system cleaner as preventive.
Estimated cost: $400-1,400
Owner tips
  • Change transmission fluid every 30,000 miles with Honda/Acura ATF-DW1 only—aftermarket fluid accelerates judder issues
  • For V6 models, check oil level every 500-1,000 miles and keep records—early detection of oil consumption can save the engine
  • Verify Takata airbag recall completion with VIN lookup before buying used—it's a serious safety issue
  • The 2.4L I4 is significantly more reliable than the V6 for high-mileage use—prioritize it if longevity matters
Buy the I4 model if you want a reliable used Acura—avoid the V6 unless you have full service records proving no oil consumption issues and can budget for potential transmission work.
