Hyundai - Heating :: Burning Smell When Heat Is On
Dec 18, 2015
Car: 2013 Hyundai Santa Fe
Problem: We have a sweet burning smell like antifreeze or oil coming from the vents when the heat is on.
We have taken it to 3 mechanics and they can't figure out what it is. We expect the heater core is going bad, but the symptoms do not fully match what we are experiencing. We do not have any leaking antifreeze, nor do we have any windows fogging. They also ran a pressure test which came back normal.

I have always had a occasionally burning smell in the cabin when I am using the heating system. Has never happened in summer. Only happens randomly in winter when I am using the heat. I don't think I have seen steam and stuff and definitely no water puddle in footwell area. This strongly makes me think that I have a leak in the heater core area, maybe not the core itself, just o-rings and things like that. Vw has checked many times and replaced the valve gaskets. But the smell is still there. This morning when the smell came, I opened up the hood immediately and I think the smell was around the passenger side plenum chamber area.

I just got this truck and didn't have any strange odors other than brake caliper which got replaced immediately. I got 4 new Mastercraft AXT tires last week and two days before that I got a muffler installed. I put a flowmaster on it (black) Now if I drive it about three four miles, I get a smell coming from somewhere which I can't locate because nothing is hot and it goes away within a few minutes so I cant pin point it. At first i thought it smelled like rubber heating up, but now not sure. I may take it back to tire dealer and have him check all the tires for balance. I had them do an alignment, so I would hope it isn't that. The smell came with the new tires I think....I had the exhaust worked on two days prior to that and didn't notice anything after that. I haven't checked anything else, but there isn't anything hot when I jump out and start sniffing around. Would tires do that if NEW or out of balance?

I have a 12 Tiguan and sometimes I get a burning smell when the heat is on. It sort of smells like wax burning. What it could be?

I have a new 2013 Hyundai Accent (automatic, 4 cylinder) with less than 1500 miles on it. The day I drove it off the lot and up until today, it randomly smells like burning rubber. It happens whether it is hot or cold, driven two miles or thirty miles. The smell is coming from under the hood but I know very little about engines, so I'm not sure what it is. I have told the dealership and they don't seem to care. I may not know much about cars but I know that that smell is not normal, especially in a new car. What could be causing this...

I have a 2000 F250 SD 4x4. I noticed the other day that after driving the truck for 10 miles or more and then stopping and getting back in it feels like the parking brake is on. I drove the truck home and on my way back I smelled brakes burning but it wasn't pulling while driving or braking. When I got home I put my head in the wheel well to get a look at the brakes on the drivers side it seemed ok, but when I did it on the passenger side it was hot as Hades! It's been my experience that if the caliper is hanging up it will pull either while braking or regular driving. I just want a better idea before I go ahead and buy a new caliper and hose and tear the dang thing apart.

Recently purchased a CPO 2009 F250SD 6.4L. Happy with the truck overall but this AM I noticed a slight burning plastic smell so I opened the hood and looked around closely. Didn't really find the culprit(I don't think) but noticed that the engine compartment heat shield/barrier appears to be falling down above and behind the turbos (pictures linked below). How big a deal is this? Would it be covered under the CPO warranty? It almost seems like a safety issue. I also wonder if the insulation material, now exposed without the metal reflector material, is what is causing the smell....

My car has been having issues lately, I'll have the heat or air on (doesn't matter which), and I'll hear a click (like a pen click) and it will go off, then it will click again and go back on. Last year it only did this a couple of times and I solved the problem by hitting the dashboard, obviously. But now it's doing it every time I drive, and since it's winter I kind of need the heat to stay on. What is the problem?

2004 Tahoe that started with no heat in rear. Checked all hoses and they get hot all the way to back. Replaced rear blend door actuator and worked for a little while. Tonight, took a 90 minute trip and it blew ice cold until suddenly it started blowing heat 45 minutes into trip but then went back to cold after about 10 minutes. Actuator is electric not vacuum. Could it be in the controls where you adjust the temp?

I'm getting heat out of the passenger side, no heat on the driver's. Does not matter what is selected - floor, dash or defrost - the driver side blows nothing but cold air.

My 2005 Honda Civic has just started doling out heat when it feels like it regardless of where I set the dial. It seem that when I am accelerating or applying gas, heat is available but when I am stopped at a light or coasting downhill, cold air is all that is available. Is this a thermostat issue or something more dire?

A few weeks ago my car started overheating and blowing cold air while I was on the highway. I took it to my mechanic and he found that the radiator was leaking. Two weeks later the car was overheating and the heater was blowing cold air when I was on the highway. I had it towed to the same mechanic and the car wouldn't overheat nor would it blow cold air. He drove it all around and on the highway but couldn't get the problems I was having to occur. Now I have intermittent heat. Sometimes I will start the car and it will take 20+ minutes for the heat to blow warm air. Other times the heat works fine for a while and then starts blowing cold air. Usually when it starts blowing cold air I begin to smell a sweet odor, possibly coolant. It hasn't overheated again, but I have stayed off the highway.
I just had the thermostat changed, and the upper radiator hose warms up quickly. When the heater is blowing cold air, one or both of the hoses connecting to the heater core do not warm up. Sometimes it's both hoses, other times the hose going in is hot but the other hose is cool. My mechanic seems to think that the head gasket is leaking air into the system, and that the air is preventing the coolant/water from being properly transported throughout the car. He did a pressure test to see if it was the head gasket when I brought the car in but it wasn't conclusive. Does it sound like a head gasket leak, or could it be a blocked heater core, or a weak water pump? So far I haven't noticed any coolant leaks, but I could be missing something.

I have a SAAB 2000 95, and the heat isn't working. I was told by a local shop that the blend door motor isn't opening to allow the system to switch from air to heat. He said that the heating system was working, but that the hot air can't exit the dash. He said it would have to be repaired at a dealership.

I have noticed a smell like heating when doing a suddenly hard acceleration (up to 6000 RPM) on my R32 2008, but when driving normally there is nothing.

The problem with the caller from CA's Subaru smelling like burnt rubber is the actual tires are heating up due to an improper torque split between the tires. Subarus are very sensitive to changes in tire pressure and thus the diameter and will wear the tires down. The driver mentioned 8 sets of tires. He has a bad torque split in the AWD system.

We purcheased a used 2003 Hyundai Elantra in Aug. 2010. Since then the driver's side low beam has burnt out 3 times. From our online research this appears often in the Elantra, but with no real fix. There does not appear to be any moisture problem and I am leaning towards a short, ground, or voltage problem. But seems odd that it is always the same headlight.

I just bought 2003 king ranch with a 5.4 it started burning coolant and the heat was coming on then while the engine was at operating temp would blow cold air. Then the temp gauge would start to rise,once it got to the top the heat would start to come on and the temp gauge would then go down to normal.I started by changing the thermostat which didn't work.
Then i figured it was air in the system I kept burping the truck at idle but it never worked, it kept burping while driving all the coolant out that i put in back out finally i took that cap off the one that clicks when you tighten it and replaced it with a cap that tightens down all the way and doesn't click. Every morning I check the reservoir fill it up to the proper level and so far so good.

On the way into work today, I smelled a burning smell in my cabin. Got to work and opened the hood and it's very clearly something burning in the engine bay.
Coolant levels are good (even opened the coolant reservoir and it filled back up a bit, so it doesn't seem there's a coolant leak there), checked the dipstick and oil level seems good. MK6 GTI, just hit 21.5k miles. The only things I can think of are:
-Haven't replaced the cabin filter
-Intake may need to be cleaned? It's been on for about 10-12k and hasn't been cleaned yet.
Might also be just because my senses are heightened because of this, but the engine sounds louder than normal, specifically the lifters sound louder, but might just me being paranoid now. Been hearing about the headgasket possible 2.0 recall that's been bouncing around, so could it be that?
I want to take this to my car guy, but he's about 1.5-2 hours away, so I'm iffy on driving it that far.

Three times in the past few months I have smelled something burning in my car. It only lasts for about 10-30 seconds. I've taken it into the shop to have checked with no results. One dealer told me I was smelling burning leaves caught in the manifold. It sure didn't smell like burning leaves to me though.

So i had a burning oil smell for 2 years. I finally brought it to the shop and had the valve cover gasket changed as well as the chain tensioner gasket. I now have a constant burn smell. It cannot be burn off because when i open the hood i see it dripping on the cat. converter i just cannot see from where. I seems to be right behind the heat shield that covers the edge of the valvle cover. What else could be wrong here?
