Common Issues & Solutions
Preventive maintenance based on known issues with this model
Snapring transmission failure (1991-1992 manual models)
critical
Cause:

Factory defect in transmission snapring allows countershaft to slip out of position, causing catastrophic failure. Affected serial numbers: J4A4-1003542 to J4A4-1005978.

Solution:

Check transmission serial number. If in affected range, preemptively replace snapring and related components before failure. Upgrade kits available from SOS and Dali Racing. Cost: $1,500-$2,500 installed.

Estimated Cost:$1,500-$2,500
Window regulator slow operation or failure
minor
Cause:

Window regulators accumulate dirt and lose lubrication over time. Motors can also fail.

Solution:

Clean window tracks, lubricate regulator mechanism with silicone grease. If motor fails, replace window regulator assembly. Common issue on all NSXs.

Estimated Cost:$200-$400 per window
Climate control system failure (auto climate models)
moderate
Cause:

Climate control unit capacitors fail with age, causing erratic operation or complete failure.

Solution:

Send climate control unit to specialist for capacitor replacement. Alternative: replace entire unit ($$$). DIY capacitor replacement possible with soldering skills.

Estimated Cost:$200-$400 (repair) / $1,500+ (new unit)
Main relay failure (no start, intermittent stalling)
moderate
Cause:

Main relay solder joints crack with age and heat cycles, causing intermittent or permanent failure. Very common issue.

Solution:

Remove and re-solder main relay (located under dashboard). Replacement relays available. Easy DIY fix. Carry spare relay in car for emergencies.

Estimated Cost:$80-$150 (new relay) / $0-$50 (resolder)
ABS system failure (ABS light on)
moderate
Cause:

ABS pump motor accumulator failure, wheel speed sensor failure, or corrosion in ABS module.

Solution:

Diagnose ABS code first. Common: wheel speed sensors ($100-$200 each). ABS pump rebuild available from specialists ($800-$1,200). ABS module repair/replacement ($1,500-$3,000).

Estimated Cost:$100-$3,000 depending on cause
Coolant hose failure (sudden overheating)
critical
Cause:

OEM coolant hoses deteriorate from inside-out after 15-20 years. Can fail suddenly without external signs of wear.

Solution:

Preventively replace all coolant hoses at 90k miles or 15 years, whichever comes first. Use quality aftermarket hoses (OEM no longer available). Do not wait for visible cracking.

Estimated Cost:$600-$1,000 installed

Honda NSX NA1/NA2 Maintenance Schedule

The Honda NSX is a mid-engine exotic requiring specialized maintenance procedures. This comprehensive maintenance guide covers both NA1 (1990-1997) and NA2 (1997-2005) models with specific attention to the unique C30A/C32B VTEC V6 engines.

Critical Maintenance Notes

TIMING BELT REPLACEMENT: The timing belt service at 60,000 miles (or 6 years) is the most critical maintenance task. Failure can result in catastrophic engine damage due to valve-to-piston contact. Budget $2,000-$3,000 for this essential service.

Mid-Engine Access: Many maintenance tasks require removing the engine cover and working in the rear trunk area. Labor costs are typically 1.5-2x higher than conventional front-engine cars.

Snapring Transmission (1991-1992): Early manual transmission NSXs have a factory defect. Check transmission serial number and replace if in the affected range before failure occurs.

Follow the maintenance schedules below to preserve your NSX investment.
