I just got my 2016 NX F Sport a week ago and currently have about 120 miles on it. Every time I park it in my garage, there is this burning plastic smell coming from it (I think from the hood). Is that normal because the car is new or should I be worried? This is my first Lexus and I have no idea if that is normal. I talked with other lexus owners and they all said their cars never had that smell.

 

I had the same smell on mine when new. I talked to the dealer and he said it was a protective coating put on the engine for shipping across seas. It eventually went away not long after.

 

First new car?

If anyone says they "never had that", it's because they simply don't remember it.

The smell is your coolant burning the hoses for the first time, your tranny fluid going thru the cooler for the first time. Your exhaust burning off labels.

It's just breaking in.

 

100% normal, I have the same thing. It is not really a burning smell, just more like a things working for the first time smell!!

 

The NX had some smells, but I think it was relatively minor for a new car breaking in.

My wife's IS was worse. It would smell the entire garage up of burned hoses and burned paper and heated fluids for 1-2 months.

The Camaro was far more worse than that. GM clutches wear in over the first 1000 miles, so if you slipped it at all to get the car moving, you'd smell it in the car, and when you got home, you'd smell clutch, rubber, paper, and fluids. People post on the forums all the time that they think they burned the clutch out of a brand new car and you have to tell them "its sadly normal" lol Now, I only smell raw exhaust thanks to the headers lol

 

You will get that smell in all new cars.
My 2011 Acura TSX had the same smell

 

I had a slight burning smell in both my IS and NX when they were new. They disappeared shortly in about a month's time. Definitely normal.

 

Ah! It's a good thing that car washes/detailers don't have that particular formula in their "New Car" scent.

 

Had the same "problem" when I first got my GS. It went away after a couple months.

 

Call me crazy, but I kinda like the smell!!

 

Maybe I'm being paranoid because I saw this thread earlier but I smelled something burning on my way to work this afternoon and my NX already has 7k miles. 😳
