1997 ACURA NSX

Symptoms: Transmission pops out of gear under load, Grinding or clunking from bellhousing, Complete loss of all gears (catastrophic failure), VIN range J4NA1 through J4NA115250 affected

Fix: Transmission removal (8-10 hours), snap ring replacement with updated spec ring, bearing inspection/replacement. Many owners opt for full transmission refresh while it's out. Preventive fix before failure is strongly recommended if VIN falls in range.

Estimated cost: $3,500-6,000

Typical onset: 60,000-100,000 mi

Symptoms: Coolant leaks from rear of engine bay, Overheating under spirited driving, Visible coolant seepage at thermostat housing, Brittle or swollen rubber coolant hoses

Fix: OEM rubber hoses become brittle with age. Complete coolant system refresh including all hoses, thermostat housing (prone to cracking), water pump inspection. Access requires significant disassembly (6-9 hours). Do them all at once—multiple return visits cost more.

Estimated cost: $2,000-3,500

Typical onset: 80,000-120,000 mi

Symptoms: Window drops into door and won't raise, Grinding or clicking noise when operating windows, Window operates slowly or binds halfway, More common on driver side due to higher use

Fix: Plastic gears in window regulator strip with age. Requires door panel removal, regulator R&R (3-4 hours per side). Aftermarket replacements available but OEM lasts longer. Do both sides preventively if budget allows.

Estimated cost: $800-1,200

Typical onset: 100,000+ mi or modified cars

Symptoms: Excessive oil consumption (more than 1 qt per 1,000 mi), Rod knock or bottom-end noise, Metal shavings in oil, Compression loss across multiple cylinders

Fix: C30A/C32B engines are bulletproof when maintained, but failure occurs from extended oil change intervals, track abuse, or botched forced induction. Full rebuild with pistons, rings, bearings, gaskets runs 40-60 hours. Short block replacement is 35-45 hours. Prevention: religious 3,000 mi oil changes, avoid cheap forced induction.

Estimated cost: $12,000-20,000

Typical onset: 70,000-110,000 mi

Symptoms: ABS warning light illuminated, Loss of ABS function (normal braking remains), Pulsing brake pedal without ABS activation, Accumulated moisture damages internal components

Fix: ABS modulator located under hood, prone to internal seal failure. New OEM units discontinued; remanufactured units or used JDM parts required (3-4 hours to replace). Can drive without ABS but resale value suffers.

Estimated cost: $1,800-3,000

Typical onset: 80,000+ mi

Symptoms: Transmission fluid drips under car, Low transmission fluid warnings (if manual, visible on dipstick), Fluid visible on undertray or bellypan, Lines corrode where they pass through chassis

Fix: Steel transmission cooler lines rust through at mounting points. Replacement requires lift access, line fabrication or OEM parts (4-5 hours). Undertray removal mandatory. Check condition during any transmission service—leaks accelerate wear.

Estimated cost: $800-1,400

Symptoms: No-start condition when engine is hot, Car starts fine when cold, fails after heat soak, Fuel pump doesn't prime on hot restarts, Intermittent starting issues in summer months

Fix: Classic Honda issue: solder joints crack in main relay from heat cycling. Relay located under dash driver side (1 hour to access and resolder, or 0.5 hours to replace). Preventive resolder recommended on any NSX over 15 years old. $50 DIY fix or $200-400 at shop.

Estimated cost: $200-400
