Camry :: Burning Smell Through HVAC System After Braking (02 SE V6)
Feb 12, 2012
Our 2002 Camry SE V6 incurs a burning odor through the HVAC system after braking from moderate or higher speeds (at low speeds, this does not happen). It can last for a few seconds or a few minutes and then goes away (it does not happen while in motion). I cannot smell anything outside the car.
The car was inspected & serviced two months ago with no issues found. The front valve cover was replaced about a year ago but the back valve cover was OK to leave as is.
I would want to say it is the brakes or the snow tires causing the odor but it is strange it only smells inside the car.

My 2003 Passat has a musty smell coming from the HVAC system that just won't go away. Have resealed pollen filter and had airsept treatment (this worked for a while, but now the smell is worse than ever). Two dealers have tried (and failed) to fix this. It's so bad I can't take passengers in the car.

Two related problems:
1) Our 2008 dodge grand caravan's recycled cabin air/exterior air flipper is broken. You know, makes the clicking clunking sound until it gives up?
2) Unfortunately this has made the exhaust smell that much worse.
Usually when you drive above 35mph you don't catch engine fumes, but when its anything less you fear you're poisoning your family into early cancer. Obviously we have a leak in the HVAC system somewhere and anytime we take it somewhere for service on something else they just shrug their shoulders.
How to locate the leak so I can keep the engine compartment out of our a/c?

This morning I noticed a strong burning odor, like burning wax. It only seems to occur on high current regen events (eg coming off the freeway). It also happens to be raining, although I'm not sure if that's part of the issue or just a coincidence.

I just picked up my new Tiguan Wolfsburg yesterday. Beautiful! Drives wonderfully! But an odd thing, I noticed that as I brake, there is this thud, thud, thud noise around the back tires; almost like something is hitting the tire because the thud interval slows as the car slows. Then, when I got out after a 10 mile drive home, I noticed the heavy scent of burning rubber. Does this sound at all like a new car settling in, or possible issues already?

I always smell oil burning when I drive my Ex.
I don't have leaky valve covers and I don't have a lot of oil on the side of the engine.
What I did notice was there was a lot of oil in the intake tract. It's coming from the tube on the left side of the engine where it connects the driver's side valve cover to the intake tube before the throttle body.
What would cause this?
My PCV valve is clean and flows one way as it should. The plunger inside moves freely.

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.

'05 1.8T with 30K miles: Sometimes, when the car is stopped and idling, an oil burning kind of smell comes in through the ventilation system. I can also smell it outside. I had the dealer (a good one) check it out. Couldn't find anything. No sign of leakage anywhere. Where I or they should be looking? When I open the hood during these smell events, I can't see any smoke or tell exactly where it's coming from. It seems to be around the driver's side of the engine, but all the heat is on the other side around the exhaust and turbo. Weird. It's really starting to annoy me.

I have a 2013 Camry SE that is, out of the blue, not blowing any air from the HVAC system. I checked the 2 A/C fuses any they are ok. The lights light up on the control panel like normal and the rear window defogger works correctly, so I don't think it's the control panel. I can't find any fuses or relays relayed to the blower motor in either fuse box.
What else should I check? The car is still under warranty (for a month!) but if it's a cheap and easy fix, I'd rather save the hassle of giving it to the dealer for a day and fix it myself.

I have a 96 camry that has a minor oil leak. I have taken it in to get checked, and the mechanic told us that as long as I'm willing to keep putting oil in it every month, I don't have to fix anything. However, lately the car has been making a burning smell, especially when I turn on the heater, and when the car is low on oil. Also, my oil cap has some yellow gunk on it. I'm concerned that this means water is mixing with my oil.

I have a 2003 Dodge Neon and recently had transmission work done on the car. When I got the car back the radiator cap was left loose, I didn't know this until I took the car for a drive and it overheated. I let the car cool down, replaced the coolant, and made sure the cap was sealed down. The car now has a slow coolant leak, when I turn the car off I can see it drip underneath for about 2 minutes and then it stops. Also, after the car heats up to running temperature I get a burning rubber smell coming through the vents. What could this be? The car only has 70,000 miles on it and I would like to keep it going if I can.

2004 V6 XLE Power Steering Leak *pics* ... The problem now? Car doesn't start. I've done all the 'usual' checks and I am totally baffled.
So I was dropping my friends off at night. When I had the car in reverse to get out of the parking spot, turned off my AC and drove to park my car on the road. My ears heard something 'different' from my engine, like a 'wurrrrr' noise. I first thought it was my power steering pump was making noise (see my previous thread why). I pulled on the side of the road this is what happened.
I open my hood to determined my fluid for PS was OK. I noticed a 'burning' smell like something rubber was burning or metal getting super hot. I turned my car off and restarted the engine. The car cranked but it crank very slowly, lights dim and it started almost like a weak battery. Maybe battery? The 'wurrr'/buzz noise was coming from the belts area and was RPM related. Car did rev fine without any hesitation. [URL] ....
As I had the car on for a minute to take a video (below), I was in my car when I noticed light smoke coming from the right side (drive belt) area. I immediately turned off my car and attempted to see where the smoke was coming from.
After 10 minutes, I wanted to see if it would still start. Nope. Just rapid clicking of starter (See : [URL] ....)
It was dark so I couldn't do much (iPhone w/ flash light app), but I did check all what I could above and below the engine. I didn't see any burn wires or grounding either. So I was thinking...
-If AC or Alternator seized up/locked up, the car would still start but belts would burn, right? Same with power steering?
-Timing belt torn or tensioner sized? If belt torn, engine would crank freely though? Tensioner would usually just make a bad noise, right? Wouldn't really account for the 'weak' starting prior I think?
-Electrical problem such as a short within alternator/ac compressor....

Lately my 2002 v6 has been smelling like it's burning oil from under the hood. Around the front exhaust manifold, there's a wet black "powder" type substance. Oil levels are fine and the car has also been driving without any issues. The car hasn't overheated but then again, I live in NJ where the temperatures don't go above 35F.
I'll be posting a picture tomorrow.
The car has 144k and the timing belt, water pump, spark plugs were done at 120k.

I have a 4 cyl 2000 camry. I notice the smell of burning oil when I shut off the car and while I'm driving. There is no black smoke coming from the tail pipe and it uses minimal oil. I removed the spark plugs and found oil on the threads of spark plug # 2, but not on the electrode. What's up?

Yesterday I made a 3 hour round trip with my car, and on the last leg coming back into town, I noticed my check engine light came on, and I saw white smoke coming from underneath the hood of my car, along with a burning smell. Luckily I was able to make it home just fine. I've googled this issue, some people have suggested coolant leak.
Also, I checked the oil levels today and they appeared to be slightly below the lowest level tick, which could be why it was having issues yesterday. Last time I got an oil change was November of 2015. I'm surprised it's this low considering I normally don't commute farther than a couple miles each day.

After my Camry XLE V6 warms up to temp it starts to smell like burning rubber - my wife states that it smells like burnt popcorn. I bought the car and I believe it had been driven for quite some time with a bad upstream rear O2 sensor - when I hooked up my scan tool to it, it showed as a bad o2 and miss on #3 and #6 cylinders - I replaced the coil pack feeding #3 and #6 and runs smooth - put a Denso OEM o2 sensor on the rear and still has a miss code but not an emissions code - still smells like burning rubber - I figured the smell was coming from the bad o2 and it running bad AF mixtures.
I figure that if the catalytic converter was plugged or needed replaced that I would get a code for it. I noticed a bit of oil around the valve cover gaskets so I gave them about a 10th of a turn down to see if it would stop the leak and steam cleaned the oil off the motor - still smells of burning rubber - car has never had the timing changed or drive belts for that matter. Drive belts look good, I will have them changed the next time serviced but I'm not sure about the timing belt...car has 218,000 miles but looks great - serviced regularly - bought from my dad and his cars last forever - what this could be?

My CPO '11 Lux has a strong odor coming from the air vents. First thought it might be some kind of air freshening canister that was injecting the fragrance, but now wondering if I have an antifreeze leak???

The water was not actually getting into the HVAC itself, but getting past the air inlet assembly from under the leaf screen directly into the firewall area. I will try a gasket maker that comes in rolls that I can press into place. there is no room for tools there.
Everywhere around the heater and AC module is dry. The foam on the inside firewall immediately under the air inlet assembly is soaked, yet the inside of the assembly is bone dry. I removed the entire to diagnose the leak. A light rain was enough to fill the back foot well with an inch of water.

I drove about 25 mi today, made a brief stop and then continued home. On the return trip, the system would not blow any air in any mode at all. While driving, I cycled it through various modes and it would not do a damn thing. Later in the day I started up and it worked fine... What might cause that to occur?

My 08 B6 wagon has a very foul odor emanating from the HVAC system. It started after my wife washed the windshield with vinegar to get rid of some scaling from the bizarre water we have here. She thought the smell was from some of the vinegar running off the windshield. Well, that was several months ago and the smell is no better. Just recently, the temps have been down enough to turn off the AC switch and the smell is even worse.
