Engine
3.5L V6 (J35A3)
Timing Belt Failure
- Symptoms: Sudden engine stoppage, loss of power, potential for severe internal engine damage if belt breaks.
- Solution: Replace timing belt, tensioner, and idler pulleys at recommended intervals (typically 90,000-105,000 miles).
- Cost: $600 - $1000
Rear Main Seal Leak
- Symptoms: Oil dripping from the rear of the engine, near the transmission bell housing.
- Solution: Replace the rear main seal. This is labor-intensive as the transmission often needs to be removed.
- Cost: $800 - $1500
Variable Valve Timing (VVT) Solenoid Issues
- Symptoms: Check Engine Light illumination, rough idle, decreased engine performance, potential for increased oil consumption.
- Solution: Replace faulty VVT solenoids and ensure proper oil levels and quality.
- Cost: $200 - $400
Transmission
5-Speed Automatic (BDGA)
Harsh Shifting / Slipping
- Symptoms: Jerking or clunking during gear changes, delayed engagement, or the transmission slipping out of gear.
- Solution: Transmission fluid and filter change, potential for internal transmission repair or rebuild if damage is significant.
- Cost: $300 - $800 (fluid/filter), $2000 - $4000 (rebuild)
Torque Converter Issues
- Symptoms: Shuddering at certain speeds, slipping, or failure to engage.
- Solution: Replacement of the torque converter, often done in conjunction with transmission service.
- Cost: $700 - $1200
Suspension
Standard Independent Suspension
Worn Ball Joints and Control Arm Bushings
- Symptoms: Clunking noises over bumps, poor handling, uneven tire wear, steering wander.
- Solution: Replacement of worn ball joints and control arm bushings.
- Cost: $400 - $800 per axle
Leaking Struts/Shocks
- Symptoms: Bouncy ride, excessive body roll, visible fluid leaks on shock/strut bodies.
- Solution: Replacement of worn struts or shocks.
- Cost: $400 - $700 (set of 4)
Electrical
General Electrical System
Power Window Motor Failure
- Symptoms: Windows not operating, slow operation, clicking noises from the door panel.
- Solution: Replacement of the power window motor and regulator assembly.
- Cost: $200 - $400 per window
Alternator Failure
- Symptoms: Dimming headlights, battery warning light illuminated, difficulty starting, dead battery.
- Solution: Replacement of the alternator.
- Cost: $400 - $700
Exterior
Body and Trim
Rattling Interior Trim
- Symptoms: Various squeaks and rattles from dashboard, door panels, or center console.
- Solution: Locating and securing loose trim pieces, applying felt tape or foam padding.
- Cost: $100 - $300 (DIY or professional diagnosis)
Sunroof Drain Clogs
- Symptoms: Water leaks into the cabin, particularly in the headliner or footwells, especially after rain or washing.
- Solution: Clearing the sunroof drain tubes with compressed air or a flexible wire.
- Cost: $100 - $250
Interior
HVAC System
Blower Motor Resistor Failure
- Symptoms: HVAC fan only works on the highest setting, or not at all.
- Solution: Replacement of the blower motor resistor.
- Cost: $100 - $250
Infotainment System
Navigation System Issues (if equipped)
- Symptoms: Disc read errors, frozen screen, inaccurate GPS location.
- Solution: Cleaning or replacing the navigation DVD/unit, software updates.
- Cost: $300 - $1000+
Summary Verdict
The 2002 Acura MDX is a generally reliable vehicle, especially considering its age. The powertrain, particularly the V6 engine, is robust if maintained. However, common issues for vehicles of this vintage include the timing belt, rear main seal leaks, and potential transmission problems if fluid changes were neglected. Suspension components like ball joints and bushings are also wear items that may require attention. Electrical gremlins, such as power window motors and alternators, can occur. Addressing these potential issues proactively, especially the timing belt replacement, can significantly extend the life and maintain the reliability of the 2002 MDX.
