Smell of Burning Rubber

[Dak2Zeke]

I picked up a 2017 Auto GT Saturday. Today I pushed it to just before redline, about 6000 RPMs. Right after, I noticed a burning rubber smell. Is this normal for a break in car or should I be worried? Car has about 300 KMs on it.

There is another thread that I started a while back that is similar...my 15 GT/PP has done that since new. After a full throttle blast my car interior smells of rotten eggs just like catalytic converter smell.
I changed the exhaust to the Ford Sport catback and later to the Corsa Extreme and it still remains the same smell....it's annoying but I learned to live with it.
Several others have had this same issue, with many saying wait till the cats get a few miles on them and it will go away....well mine never did.

I never went back to the dealer with this issue since I swapped exhausts early on just for them to say it's the new exhaust....but it was like that from day one.

Ok, so it's not a break in thing? Does your car run well or give you any drivetrain issues?

Pretty normal on new cars. Just grease and oil getting evaporated off the exhausts and stuff.

My car STILL emits that smell after applying anywhere from 60 to 100 percent throttle. It almost has 7,000 miles on it, by the way, so I'm not sure why it still makes that smell. Regardless, it runs like a champ so :shrug:

Thanks guys! To follow up just a few more questions, 1) do I need to warm up the car upon starting it up? And 2) Does it come with full synthetic oil or semi synthetic?

The GT runs good, no complaints...just the smell...:eyebulge:

I don't know, why some do and some don't....it's not consistent with all mustangs..???

It just happens you smelt it.
Some people probably never noticed it.

My car has almost 20k and stinks if you beat on it real hard. Not sure if there is an exhaust leak or what but it's something I have grown accustomed to.

Had mine for a month now and she stinks sometimes when I put her up after I get home. Hoping it wears off. At about 1300 miles now.

Depends on what you mean by warming up. Modern cars do not need to sit at idle for any extended period after start. However, you should not floor it immediately after (or shortly after) start. Drive normally until at operating temp.

The smell in mine is very noticeable...can't miss it. Smells like farts after taco bell...very noticeable...:doh:

In the winter I warm it up for about 5 minutes before moving and in the warmer seasons I warm it up only for about a minute. In both circumstances I won't apply any aggressive throttle until the car is fully up to temp.

The car comes with semi-synthetic from the factory but I switched to full synthetic.

I love me some Taco Bell, that's a terrrible thing to say.

mine has stopped making that plastic burning smell around 15k miles
it will still make that burning rotten eggs smell due to the cats, which is normal under high load/throttle
