Common Problems & Known Issues

The 2010 Acura RL is Honda's flagship sedan with a 3.7L V6 and available SH-AWD. While generally reliable, this generation suffers from catastrophic transmission failures and a notorious VCM (Variable Cylinder Management) engine problem that can destroy internals if not addressed.

Automatic Transmission Failure (5-Speed)

Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Harsh or delayed 2-3 shift, especially when cold, Shuddering or slipping under light acceleration, Metal shavings in fluid during service, Complete loss of 3rd or 4th gear, limp mode
Fix: The 5-speed automatic has weak clutch packs and the torque converter can fail. Fluid changes every 30k help but don't prevent eventual failure. Rebuild runs 18-25 hours labor, remanufactured unit swap is 12-15 hours. Transmission oil cooler often replaced simultaneously as it's a common failure point that contaminates fluid.
Estimated cost: $3,500-5,500

VCM (Variable Cylinder Management) Piston Ring Failure

Occasional · high severity
Typical onset: 90,000-150,000 mi
Symptoms: Excessive oil consumption (1 qt per 1,000 mi or worse), Blue smoke on startup or acceleration, Misfires on cylinders 1, 4, or 6 (the cylinders that deactivate), Fouled spark plugs, carbon buildup
Fix: VCM causes cylinders to run cooler when deactivated, leading to oil control ring fouling and eventual ring land failure. Requires engine disassembly, new pistons, rings, honing, often head gasket replacement. 25-35 hours labor. Many owners install VCM disable device (VCMuzzler) preventively, but damage may already be done by 100k. Short block replacement is sometimes more cost-effective than rebuild.
Estimated cost: $4,500-7,500

Takata Airbag Inflator Recall

Common · high severity
Symptoms: Recall notice from Acura (multiple campaigns), SRS light may or may not be present, Inflators degrade over time, especially in humid climates
Fix: Both driver and passenger airbag inflators subject to recall due to explosive rupture risk. MUST be addressed before purchase or operation. Dealer-only repair, covered under recall at no cost. Takes 2-4 hours depending on parts availability. Check recall status by VIN before buying any RL.
Estimated cost: $0 (recall repair)

SH-AWD Rear Differential Fluid Contamination

Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Grinding or whining from rear on tight turns, SH-AWD warning light intermittent or steady, Clunking when accelerating from stop, Vibration at highway speeds (AWD models only)
Fix: The active rear differential uses special Honda DPS-F fluid that breaks down or gets contaminated. If neglected, internal clutch packs and electric motors fail. Fluid service every 30k miles is critical but rarely done. If caught early, fluid flush (2 hours) solves it. Once clutches are damaged, differential replacement is 8-12 hours labor.
Estimated cost: $200-4,000

Motor Mount Failure (Especially Transmission Mount)

Common · low severity
Typical onset: 70,000-110,000 mi
Symptoms: Clunk when shifting from Park to Drive or Reverse, Excessive vibration at idle in Drive, Engine rocks noticeably during acceleration, Visible fluid leaking from hydraulic mounts
Fix: The hydraulic transmission mount and front engine mounts deteriorate, especially if transmission has been slipping (extra heat). Transmission mount alone is 2.5-3.5 hours, all three mounts together is 5-6 hours. Failing mounts accelerate transmission wear by allowing excessive movement.
Estimated cost: $400-1,200

Power Steering Pump Whine/Leak

Occasional · low severity
Typical onset: 90,000-130,000 mi
Symptoms: High-pitched whine when turning at low speeds, Steering feels slightly heavier, especially when cold, Fluid leak visible on left side of engine bay, Low power steering fluid level repeatedly
Fix: Pump seals degrade and internal components wear. Hoses can also weep. Pump replacement is 2-3 hours labor. Pressure hose and return line should be inspected simultaneously. Delaying repair can lead to rack damage.
Estimated cost: $600-1,000
Owner tips
  • Change transmission fluid every 30,000 miles religiously with Honda DW-1 or Z1 ATF — this is the single most important maintenance item
  • Install a VCM disable device (VCMuzzler or similar) if you plan to keep the car past 100k and oil consumption hasn't started yet
  • Verify all Takata airbag recalls completed before purchase — check NHTSA database by VIN
  • SH-AWD models: change rear differential fluid every 30k with Honda DPS-F; independent shops often skip this or use wrong fluid
  • Watch oil consumption closely after 80k miles; more than 1 quart per 3,000 miles means VCM damage is underway
Buy only if transmission and airbag recalls are documented as completed, oil consumption is minimal, and you can commit to aggressive fluid service intervals — otherwise the repair costs will exceed the car's value quickly.
