As the first-generation NSX continues to age, failing electronics have become more common.

The most common issues include PGMFI relay, climate control unit, and stereo amplifier unit failure. The typical climate control unit (CCU)  failure symptom is the fan motor only blowing on high and/or the unit no longer powering up. The typical symptom of stereo amplifier failure is popping and/or reduced volume from the speakers. As for the PGMFI relay, no repair program is active and would require replacement of the relay upon failure. 

Lately, new electrical component failures have been reported, including issues with the stereo head unit, instrument cluster, Turn signal cancellation module, and electric power steering control unit.

The failures in the climate control, stereo amplifier, and recently the stereo, instrument cluster, Electric power steering control unit, and turn signal cancellation module are related to the electrolytic compound leaking from the
