Hello

Something I've observed on my 2017 CRV since new is that compared to my old grand am, certain outdoor odors penetrate the cabin extremely well when the air is not on recirc.

Most noticeably is cigarette smoke from a vehicle close to me when stopped at a light.

Wondering if this is considered normal for the gen5 Honda's or if I should be checking my cabin filter/talking to the dealer about it.

Thanks!

I don't think that is normal. My 2018 CR-V seems fairly air tight. If you happen to have a passenger in the vehicle, just blame any malodorous odors on the heating system.
Anyways, doesn't everybody enjoy a good stink? :)

My vehicle is pretty smell proof on the recirc mode but just like you if I turn that off I can smell the gas and smoke smell from all the vehicles in front of me. It has pretty much been the same on all my vehicles except that on Recirc mode the Honda seems to be a bit more air tight inside.

It depends. Outdoor air comes in right under the windshield for the ventilation system. If there is smoke sweeping up there, it will come in. Not sure that's a flaw.

You can get an aftermarket charcoal cabin filter which helps some.

Yeah, I have noticed it also. First time, I thought what the heck and then noticed a guy smoking in the car in front. I actually for awhile, blocked the air intake vents with black duck tape. Works during the summer, but in winter had too much cabin moisture for it to really work. In winter, most folks here keep their windows closed.

Also, I don't pull up as close at stoplights as I used to do. And I have learned if I see some smoky diesel older diesel/oil burning car to rapidly hit the recir switch.

One of the few times where I've noticed the recirc not working well enough, is when I drive along I-5 (here in CA). There is a huge cattle feedlot along the way that is notorious for it's odor. You can smell it well before you approach and after you pass it. Even with the recirc on miles before approaching, the smell still gets into the car somewhat.

Along these lines, I've noticed that if I turn on recirc AFTER encountering something smelly, like a dead skunk, the smell then just get's trapped inside the car because it's now recirculating inside the car.

As far as I know all vehicles have a vent near the rear that allows air in even when on Recirc mode.
It makes sense because if that was not there you would probably have a CO2 building up on a long drive. Whenever I get a bad smell in the vehicle I open the sun roof for a minute or two and let the air out.

If your an ex smoker you become really sensitive to the smell of cigarettes. At least that is what I have noticed.

I recall on a previous vehicle the OM indicated that the recric position provided between 80% and 90% recirculated air and 10% to 20% outside/fresh air. Not sure if Honda follows this as well, but I wouldn't be surprised.

EDIT: I found this on a Lexus Q&A: The air conditioning system is designed to allow up to approximately 10 percent of the air coming from the air vents to be fresh air from the outside. The exact amount of fresh air entering the vehicle on recirculation mode will vary.

If the A/C system is turned on in the AUTO mode, then the A/C ECU switches the air intake ducting between "fresh," "fresh and recirculation mix" or "recirculation" according to the required outlet air temperature that the ECU calculates. This calculation is based on the following:

• Temperature Dialed in with the Control Knob
• The Interior Air Temperature
• The Operating Conditions
