This isn't about the S2000. This is the only automotive forum that I frequent, so I hope I can get some insight on my current problem. This is for a 2000 Honda Accord.

Recently I've been hearing weird sounds, like buzzing, under the hood. At first the sound was around the alternator/power steering. Not long after, specific instrument warning lights flash on and off. Specifically, the battery, brake, and all door sensor warning lights periodically flash. This morning with the car off, I realized when I pressed down on the brake pedal, I could hear a hissing sound from the brake master cylinder. Futhermore, the maintenance light is on, but that was on a longtime before these problems arised. I assume the maintenance light comes on at a specific mileage (currently around 75k). What's going on with my car?

Thanks for your time guys and gals.

 

Then should be in Car Talk.

 

I would take it to a dealer you trust and have them give a go at it.

 

moving to car talk

 

Without knowing the car's history, it's difficult for anyone on a forum to determine what the problem is. Has anything been done to the car (ie. have you installed anything recently) or has anything happened that could have caused these problems to occur?

Your best bet would be to take it to a dealership or competent mechanic. Good luck.
