Strange Noise coming from 2020 Honda Civic EX-L

[midnightpi]

Hi all,

I just picked up a certified used 2020 Honda Civic EX-L with 23k miles (upgraded from a 2017 Honda Civic EX-L that someone ran into me and totaled). Super familiar with Gen X Civics.

I’ve had this vehicle for about 3 days and am starting to hear a faint but annoying sound coming from the passenger side of the vehicle. It was not noticed during my test drive prior to purchase. It’s hard to tell, but I believe it’s coming from front vs the back. Seems to happen when accelerating, maybe between 2-3k rpm. I tried toggling the A/C off and I don’t think that has any affect in case it was one of the notorious A/C issues.

My wife is calling me crazy because she doesn’t hear it - but I definitely hear. It’s like a singular toned whine/whistle sound. Video below, turn the volume up and it’s present after about 5 seconds or so in.

1) Am I crazy and just hearing it on my
own?

2) If you hear it, any suggestions to root cause?

I don't hear it.

Like Brandon said, there's nothing in that clip that sounds odd. That doesn't mean it isn't there.

Alrighty - yeah, it mixed on my friends/family that I’ve shared this with. Half can’t hear it then half do hear it. It sounds like a radio wave sound, like a dog whistle but low-ish tune. I’ll have to wait a bit and see if it gets louder/take a new video.

did the 2017 have a turbo?

 

[gtman]

Ronny, all EX-L's are turbos.

 

[midnightpi]

Yes. So I’m used to the Turbo sound coming from my 2017. Maybe it’s a different sound than what I’m used to that could be completely normal. I’ll have to wait and see if it’s more pronounced. New used car worries, you know?
Other than that sound, things seem good. This car market is dumb though. I probably paid just a bit too much for this Civic ($25k) but I really enjoy the Gen X lines and am just so used to them.

 

[gtman]

Actually, in my area, a 2020 EX-L with only 23K miles typically sells for 25k plus.

 

[midnightpi]

Oh right. I guess I meant that MSRP back in the day was the same amount basically, so there hasn’t been much depreciation on the car. I could’ve bought new now, but there’s some features of Gen X that the newer ones don’t really have. Plus I like the body style of the Gen X’ers better.

 

[Pbergmann]

I don't hear it.

Yea, me either.

I downloaded and amplified it. It's like a major third interval from the idle tone. That, to me, suggests a harmonic resonance. But it could be anything that's resonating.

Since it comes and goes; I wouldn't worry that much.

 

[midnightpi]

Thanks for attempting and validating there’s something there. I still hear it from time-to-time, but comes and goes. If anything major, I still have bumper-to-bumper and should help cover it. Doesn’t seem to affect performance, just my ear that catches it. I play music, so I pick up tones pretty well.
