HFC smell? - hard acceleration

mults · 09-20-2012, 08:27 PM

Have you tried different brands of gas? Maybe there are some additives in the gas that you are using that is causing the smell. I have Berk HFC and CBE and I do get a little exhaust smell, so I need to get underneath to see if any of the bolts have loosened up a bit.

When I got my Santa Fe in 2003, there was a smell that the dealer was caused by certain gasolines. However, it really didn't seem to matter which gas I used.

Mine does this occasionally too. Smells kind of like hot brakes, but I only get it under hard acceleration. When I was researching buying a G before I bought this car I remember an issue where oil was pooling around a rear spark plug. Haven't looked at mine yet. It is really not too bad at this point, and since it really doesn't seem like oil I haven't been real concerned.

Another weird smell issue I have is when the car sits overnight on a cool night, when I start the next morning with the AC on Fresh, within 10 sconds a strong hot plastic sort smell that goes away within another 10 seconds. Won't do it again until it sits overnight on a cold night.

Yes! this is the the same smell this weekend, this wasn't there before HFCs so im guessing this is def the case, as my brakes work just fine and had no such smell under hard braking as well.
