Hmm, thats wierd...Since you have A/C on while this stink comes in..are you also on re-circulate too?..this will help you decide if the smell is from the inside or the outside

 

that's a thought right there. did you step in a pile of local critter manure? maybe as you go faster, your fan spins faster and wafts the aroma of partially digested vegetation and other minute bacterial microbes around the cabin of the truck. i know Maui had some massive cow pies at one of our sites above Kihei, i thought it was quicksand and i'd never hit solid terra firma . . . .

 

It other words..do you have chit on your shoes?...

But it also could be a fungus amongus growing in your evaporator plenum

 

Oh..Maybe it's your fan speed resistor block and it gets hot as hell...Do the H3's have these even for fan speed control?

 

Well it's not stink like $#!t - more synthetic, plastic...It can't be heat either because I drive my truck all day and no smell, it's only when I'm climbing hills or accelerate over 50.

The run we had up peacock flats was a good5 hours of driving all up steep hills, rough terrainand no smell. It wasn't until I tried climbing a hill to test the flex on the H3 I noticed the smell, of course I was revving the engine to get my H3 up there. Normal driving - no smell, accelerating over 50 - smell - strong burning smell but no smoke. Weird, I know.

 

One day bro! LOL

A buddy of mine Mike isworking with the State on getting a 4x4 obstacle course for all 4x4 vehicles built near the industrial areas of Honolulu. Once that's built we'll ship all your asses down here and we'll wheel and surf all day !!!

 

I have had the same issue for about two weeks now. I cannot figure out what it is. I have to say it doesn't smell like burning plastic though. I work for a plastics company and I know the smell of burning plastic. I am getting more of a burning rubber smell. When I have my heat/defrost on is when its' really noticeable and if I am driving for awhile with no stopping and finally come to a stop it's even worse. Did you ever find out what the issue was with your wife's friends H3?

 

Hey dude/dudettes. I have had that smell every day and 29.5k miles I have had the H3. It's very mild, but it's there, always. My theory is that it's the differential or brakes burning. It smells like it's coming from the brakes. It could be the material in the brake pads that is heating up and smelling. I told my dealer about it and they said they all smell like that and it's just a smell when the parts heat up. Now, I don't smell it coming through the vents ever, so you have a more severe case of the smellies.

 

If you smell rotten eggs I know what that is...when you figure it out keep us posted just incase we start smelling too.

 

Hey..the past couple of days I've had that burning rubber smell too. I thought I was crazy...well at least my wife thought I was, when I would get out and sniff around the truck after driving it.
