2022 ACURA NSX

Typical onset: 30,000-60,000 mi

Symptoms: transmission overheating warnings on dash, limp mode after spirited driving, burnt ATF smell, metallic debris in fluid during service

Fix: The 9-speed DCT runs hot by design, and the factory cooler is undersized for track use or aggressive street driving. Cooler fails internally, contaminating fluid. Requires full transmission drop, cooler replacement, fluid flush, and often new clutch packs if debris circulated. 12-16 hours labor at a shop familiar with the platform.

Estimated cost: $4,500-7,500

Typical onset: 20,000-50,000 mi

Symptoms: clunking on hard acceleration or deceleration, vibration through center console at idle, harsh engagement in reverse, visible cracking or separation of rubber mount

Fix: The rear-mounted DCT sits on a hydraulic mount that takes massive torque loads from the twin-turbo motor and instant electric torque. Heat cycling cooks the rubber. Replacement is straightforward but requires lift access and supporting the transmission. 3-4 hours labor.

Estimated cost: $800-1,200

Symptoms: stumbling under full throttle above 6,000 rpm, lean codes P0171/P0174, loss of boost pressure, fuel pressure drops under load

Fix: High-pressure fuel system is sensitive to contamination, especially on cars that sat on dealer lots or went straight to track use. Filter clogs prematurely. Located under rear clamshell, requiring partial body disassembly. 4-5 hours labor for filter and system cleaning.

Estimated cost: $1,200-1,800

Typical onset: 40,000-80,000 mi

Symptoms: rattling noise on cold start that disappears when warm, intermittent overboost codes P0234, slight loss of peak power, audible fluttering during deceleration

Fix: Wastegate actuator rods wear in the bushings, causing play and inconsistent boost control. Not a safety issue but annoying and can lead to overboosting. Requires turbo removal for rebuild or replacement. Each turbo is 8-10 hours labor due to tight engine bay packaging.

Estimated cost: $3,500-5,500

Typical onset: 40,000-70,000 mi

Symptoms: hybrid system warning light, reduced electric motor assist, battery cooling fan runs constantly, loss of Sport+ mode availability

Fix: The lithium-ion battery pack has active cooling that can fail due to clogged condenser or fan motor failure. System will derate hybrid performance to protect the pack. Diagnosis requires Honda HDS scan tool. Fan replacement is 2-3 hours, condenser cleaning adds 4-5 hours if clamshell removal needed.

Estimated cost: $1,500-3,200

Symptoms: knocking noise at idle when hot, low oil pressure warnings, metallic debris on magnetic drain plug, bearing material in oil analysis

Fix: The J35 block wasn't designed for sustained high-RPM, high-boost track work without upgrades. Connecting rod and main bearings can spin if oil temps exceed 280°F repeatedly. Requires engine-out service, full teardown, and bearing replacement minimum. If crank is scored, it's short-block territory. 40-60 hours for full rebuild.

Estimated cost: $15,000-25,000
