Common Problems & Known Issues

The 2007 Acura RL is Honda's flagship sedan with Super Handling All-Wheel Drive (SH-AWD) and a 3.5L V6. While generally solid, it's known for catastrophic transmission failures and the industry-wide Takata airbag recall that affects every unit.

Automatic Transmission Failure (Internal Clutch Pack / Torque Converter)

Common · high severity
Typical onset: 80,000-130,000 mi
Symptoms: Harsh or delayed shifts, especially 2nd to 3rd gear, Shuddering during light acceleration or lockup, Check engine light with P0730, P0740, P0780 codes, Transmission slipping under load or total loss of forward gears
Fix: The 5-speed automatic in the RL is failure-prone due to clutch pack wear and torque converter issues. Rebuild requires 12-16 hours labor; many shops recommend reman units. Transmission oil cooler often replaced simultaneously as contamination accelerates failure.
Estimated cost: $3,500-5,500

Engine Piston Ring Failure / Excessive Oil Consumption

Occasional · high severity
Typical onset: 90,000-150,000 mi
Symptoms: Burning 1+ quart of oil every 1,000 miles, Blue smoke on startup or during acceleration, Fouled spark plugs (oil-soaked), Loss of power and rough idle as rings deteriorate
Fix: The J35A8 V6 can suffer piston ring carbon buildup and eventual failure, especially if oil changes were stretched. Requires engine teardown, new rings, honing, or short-block replacement. 18-24 hours labor for proper rebuild with head gasket service.
Estimated cost: $4,000-7,000

Takata Airbag Inflator Recall (All Units Affected)

Common · high severity
Symptoms: NHTSA recall notices (multiple campaigns 15V-574, 16V-865, others), Airbag light may or may not illuminate, Risk of metal shrapnel injury during deployment
Fix: Every 2007 RL has driver and passenger Takata inflators that degrade over time, especially in humid climates. Replacement is FREE at Acura dealers under recall. Verify completion before purchase—this is a safety-critical item that can kill occupants.
Estimated cost: $0 (recall repair)

SH-AWD Rear Differential Fluid Contamination / Seal Leaks

Occasional · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Clunking or grinding from rear during tight turns, Visible fluid leak at rear diff pinion seal or axle seals, Metallic whine or howl that changes with speed, SH-AWD warning light if electronic clutch pack overheats
Fix: The rear differential in SH-AWD is complex with electromagnetic clutches that require clean fluid. Seals fail, water intrusion occurs, and internal damage follows. Fluid service every 30k miles prevents most issues; if damaged, expect 6-10 hours for rebuild or replacement.
Estimated cost: $800-2,200

Power Steering Pump / High-Pressure Hose Leaks

Common · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Whining or groaning noise when turning, especially cold, Fluid leak visible under front of engine (passenger side), Heavy steering effort or complete loss of assist, Low fluid level in reservoir despite no external drips (hose weepage)
Fix: High-pressure hose deteriorates from heat cycling; pump follows if run low. Hose replacement is 1.5-2 hours, pump adds another 2 hours. Flush system completely to prevent premature pump failure. This is a recall item (15V-527) if within campaign scope—check VIN.
Estimated cost: $400-900

Front Lower Control Arm Bushings / Ball Joints

Occasional · low severity
Typical onset: 80,000-120,000 mi
Symptoms: Clunking over bumps or during braking, Steering wander or vague on-center feel, Uneven tire wear on inside edges, Failed state inspection for worn ball joints
Fix: Front suspension bushings dry out and crack; ball joints develop play. Control arms are typically replaced as assemblies (bushings not serviced separately on many aftermarket parts). 3-4 hours per side with alignment required afterward.
Estimated cost: $600-1,200

Alternator Failure (Voltage Regulator / Bearing)

Occasional · medium severity
Typical onset: 100,000-140,000 mi
Symptoms: Battery light on dash or flickering lights, Voltage gauge below 13.5V or fluctuating wildly, Grinding or whining noise from alternator pulley, Dead battery after short drives or overnight
Fix: Denso alternator regulator fails or bearings seize. Replacement is straightforward but requires serpentine belt removal and working around tight engine bay. 2-3 hours labor; use OEM or quality reman to avoid comebacks.
Estimated cost: $500-800
Owner tips
  • Change transmission fluid every 30,000 miles with Honda ATF-Z1 to extend life—this trans is fragile
  • Service SH-AWD rear differential fluid every 30k miles; never skip this on AWD models
  • Monitor oil consumption closely after 80k miles; catch piston ring issues early with frequent checks
  • Verify Takata airbag recall completion at Acura dealer before purchase—it's life-or-death
  • Inspect power steering hoses annually for seepage; early replacement prevents pump damage
A comfortable, well-equipped flagship that's undermined by transmission grenades and expensive engine oil consumption—buy only with meticulous service records and completed recalls, or budget $5k for major repairs within 20k miles.
