Diagnosing this will be subject to a process of elimination. It could be the radio, blower motor or any other accessory particularly ones with moving parts; Try switching those off and try to note when this problem occurs and what is on/whatyou are doing. Something is getting hot causing the smell so it will be a situation where the accessory will have to run a while before doing it. It is a possibility that there is an electical curcuit overheating, but less likely. Lets rule out accessories first and give us an update. GL

    I have the same problem, just when I turn on the heat.

    I also have this problem, in the winter when you have the heat on. Now, I've noticed smoke coming from under the hood. Has anyone found a solution to this problem. 2003 Cadillac CTS.

    My 03 cts did this and the smellw as most noticeable in the winter with the heat on. it turned out to be a bad seal that was causing a very slight oil leak. the smell was the oil dripping down onto the exhaust or something else hot and burning. check your oile level!! see if it is slowly leaking. It is supposedly a known problem with the car. Hope this is helpful for someone..

    I too experienced this problem after the Cadillac dealership over filled my engine oil during a routine oil change. They wanted $550 to replace the two valve cover gaskets where the oil was leaking. I purchased the parts for $35.00 and spent three hours replacing them following the Chilton instructions available online from my local library.

Coolant looks like chocolate milk, burning smell


You may have a blown head gasket allowing coolant to contaminate the oil. This an expensive fix (likely $1500 +) as you will likely need to replace one or both head gaskets.

Oil smoke.coming from both sides of engine


Check your rocker cover gaskets for any signs of oil leaks. Oil leaking from your engine can contact the exhaust headers, or other hot parts of the engine and can burn, resulting in smoking and a burning smell.

My car smells like burning rubber inside- 2003 cadillac CTS, is it safe to drive


look under the car at the exhaust you might have a plastic bag melted to the exhaust causing the smell. you can leave it and let it burn off. You can also jack the car up if you feel comfortable doing so and scrap off as much as you can. That is a common result, if not a bag could be a serpentine belt failing.

Have a 2003 Cadillac CTS that I first smelled a rubber burning smell come out of a/c vent while sitting at the light only. Then today went to go home and heard all familiar noises when you start a car but...


Hello, I dont know if I can help you or not but this is what was going on with my car: It had the same smell coming out after the car was warm enough. It smelled like rubber burning. I took it to the GM Goodwrench and they thought it was just a loose nut that caused an oil leak. So they fixed that but it still had that smell. We discovered it was our power steering fluid leaking onto the engine. Now maybe your smell is from leaking transmittion fluid and the car's security systems are a pain in the ****. They will lock the car from starting if it thinks you hurt the car. I dont know if this helped but I hope it did.
