I drove my new 2019 Mazda6 back home from dealership. I really like the car. Have driven it now about 150 miles, but still there is an engine burning smell that comes insides the cabin area. I notice it when car comes to a standstill / idle usually (after it has been running on highway).

I called the salesperson, he said its very common issue for people, since the factory as well dealerships use cleaners and stuff but that it will go away soon. I am finding it harder to believe. I get a new car usually every year, though this is my first Mazda.

Could others comment with their experience?

 

New CX-5, same issue. When we first took it out for a test drive we were at a stop light with a large truck in front of us. I said, that truck really stinks and the sales rep indicated it might be my vehicle. Something about anti corrosive coatings applied to the exhaust system at the factory. It's nasty, really smells like a badly tuned diesel in front of you. He indicated it would dissipate after a couple hundred miles. It's worse when you are idling and the vehicle is not moving. You can minimize it by turning off the climate blower motor until you start moving again.

 

In my recent 2020 mazda 3 and my current 2021 mazda 3 i dealt with that smell. I honestly forgot about that being an issue. At some point in both my cars the smell ended up going away. Not sure how long it took.
Part of what i do involves a lot of driving so maybe it wore off quicker than yours do to constant driving.

 

smelled this with my new car as well...glad i know what it is now

 

All smells that you are unaccustomed to coming from a new vehicle should be addressed at the service department of the dealership. No other department!!!

This way it goes on the VIN record, and should anything actually happen then you are covered under your warranty with a record of reporting the smell.

 

I am only asking because it just dawned on me, do you actually now own a MAZDA?

 

yes see my signature below

it's a new car...i searched here as well as the web to confirm that is was a coating burning off...no need to go to the service department unless it doesn't burn off and go away after a few hundred miles...everywhere i read this is typical for a new mazda

 

No this is bad advice ^^^^^^ as I responded earlier why you should be prudent and go to the Dealer Service department! Ever see a car just catch on fire for no apparent reason and burn down to the ground? Later determined that a small plastic cover dislodged and melted on the CAT which led to the fire. I could give a few more example of new vehicles catching fire but I think one should be enough to realize that it is important to act on your feelings and thoughts regarding what you think is a new car common new car smell and not. Or for that matter any new smell that come up even on your old daily driver! If you don't know the cause, find a professional that does!

That burning smell in a new car can sometimes be due to residual lubricants, protective coatings, or cleaning agents applied during manufacturing or by the dealership. These coatings can create a noticeable smell, especially when heated, and they usually burn off after a few hundred miles.

However, if the smell persists beyond that or seems strong, it’s worth double-checking with a service technician just to rule out any oil or coolant leaks or issues with exhaust insulation. It’s great that you reached out to the dealership, and it sounds like they’re confident it will go away—but definitely keep an eye on it, and if it doesn't clear up soon, you could ask them to inspect it further.

 

I am thinking that you use a translator. The words "BURNING OFF" may not exactly be the best use? Also new car smell has been around for almost EVER regarding new manufactured cars. I might add that I am not sure what or where you thought that there are "coatings" on newly manufactured vehcles either or it may only be an ansumtion. They dont and if they did they would need to state there use and what they are. Most countries now have strict reguations reagarding the manufacturing and inportation of vehcles from automanufactures. The smell are for the most part the actatual materials used and them beingg new not coated.
This can be confirmed by merely contacting any leading auto manufacture in the world and asking them!

As for the new car smell going away after a short time this is also a half misconception. Anyone that keep [their car interior clean will have that smell for month and years. And if you clean the interior with neutral cleaning aides and store the vehicle with the windows closed that new car smell will somewhat return.
