The 2002 RSX is a solid Honda K-series platform with excellent potential, but transmission failures and second-gear synchro grind are the dominant concerns. Engine internals rarely fail unless severely abused or modded, but when they do, the repair history shows complete rebuilds rather than simple fixes.
Second Gear Synchro Failure (Manual Transmission)
Common · medium severityTypical onset: 80,000-150,000 mi
Symptoms: Grinding or crunching when shifting into second gear, especially when cold, Difficulty engaging second gear without forcing, Eventually becomes impossible to shift into second without double-clutching
Fix: Transmission removal and rebuild with new synchro rings, bearings, and seals. 8-12 hours labor depending on shop efficiency. Many owners opt for upgraded brass synchros during rebuild.
Estimated cost: $1,800-3,200
Automatic Transmission Failure (5-Speed Auto)
Common · high severityTypical onset: 120,000-180,000 mi
Symptoms: Harsh or delayed shifts, especially 2-3 or 3-4, Slipping under acceleration, Transmission overheating, burnt fluid smell, Check engine light with P0730, P0740, or shift solenoid codes
Fix: The BDGA automatic is weak behind this engine. Rebuild typically required at 10-14 hours labor, but many shops recommend replacement with low-mileage used unit (6-8 hours) due to cost. Torque converter and valve body are common internal failures.
Estimated cost: $2,500-4,500
Transmission Mount Failure
Common · low severityTypical onset: 60,000-100,000 mi
Symptoms: Clunking when shifting or accelerating hard, Excessive engine movement visible from engine bay, Vibration at idle in gear
Fix: The rear transmission mount (torque rod) deteriorates predictably. Aftermarket urethane mounts last longer but transmit more vibration. 1.5-2 hours labor for mount replacement.
Estimated cost: $200-400
Ignition Switch Failure
Occasional · high severitySymptoms: No crank, no start despite good battery and starter, Intermittent electrical loss while driving, Dash lights flicker or all warning lights illuminate, Key feels loose in cylinder
Fix: Honda ignition switches of this era fail internally. Not a recall item on RSX specifically, but same design flaw as other models. Replace switch assembly, 1-1.5 hours labor. Critical safety issue if it fails while driving.
Estimated cost: $250-450
K20 Engine Internal Failure (Modded or Abused Cars)
Rare · high severityTypical onset: varies widely
Symptoms: Rod knock or bottom-end noise, Severe loss of compression, Metal shavings in oil, Catastrophic failure if bearing fails
Fix: Stock K20A3 (base) or K20A2/Z1 (Type-S) are bulletproof when maintained, but poorly-executed turbo builds, money shifts, or severe neglect cause piston, rod bearing, or crank failures. Complete rebuild: 16-24 hours labor. Repair data shows full short-block or complete rebuilds, rarely economical on high-mileage examples.
Estimated cost: $3,500-6,500
Exterior Lighting Recalls and Moisture Intrusion
Occasional · low severitySymptoms: Condensation inside headlight or taillight housings, Headlight bulbs burning out prematurely, Corrosion on bulb sockets
Fix: NHTSA recalls addressed some headlight issues, but moisture intrusion continues. Aftermarket housings are poor quality. OEM assemblies are expensive but necessary for proper seal. 1 hour labor per side to replace and reseal.
Estimated cost: $300-700
Clutch Hydraulics Failure (Manual)
Occasional · medium severityTypical onset: 100,000-150,000 mi
Symptoms: Clutch pedal feels soft or spongy, Difficulty shifting into gear, Pedal slowly sinks to floor when held down, Fluid leak visible at master or slave cylinder
Fix: Master or slave cylinder failure. Slave is internal to transmission bellhousing, requiring trans removal. 6-8 hours labor if doing slave. Replace both while trans is out. If just master, 2 hours labor.
Estimated cost: $400-1,200
Buy a manual Type-S if you can find an unmolested one; avoid automatics entirely due to transmission weakness, and steer clear of any RSX with sketchy mod history or deferred maintenance.
