I have an '08 Infiniti EX35. When my foot is on the gas pedal, I hear a subtle, but high-pitched ringing noise. It sounds electrical like the noise a tv would make. It’s not coming from the engine. It’s very annoying and only happens with the foot on the gas. Any thoughts/suggestions?
I never had too many ringing problems. The ones I had were related to key rings that allowed the keys to hit something. I had tapping noises when turning corners that were key related but nothing constant like your noise.
Check your windows and seals and look around the engine compartment and hope for good luck.
