inside chemical smell

It has little or no "new car smell" so I have no idea what you're talking about.

 

As did the previous post, many people have commented, some with disappointment, that a new Prius doesn't even have a new car smell. You'd better get a dealer to check out your chemical smell.

 

Mine had the new car smell, still has a faint whiff! Certainly not an unpleasant chemical odor!

 

Our car had minimal new car smell and it dissipated quickly.

The all weather mats were a different story. When I took them out of their plastic covers, they smelled so bad that I wouldn't have them in the car. I was going to return them but after leaving them in the garage for a month, after a month of warm (for Victoria) weather, the smell had reduced to an acceptable (low) level and that went away in a reasonable time.

 

There was a new car smell for me, but it wasn't as strong as previous new cars i've been inside.

 

Mine also had a "urea" odor that came from the AC vents. My guess was the plastic had a bad smell used in the venting system. I did solve it by purchasing a product called "Little Trees" New Car Scent.

Here's what I did:
I took out the cabin air filter and placed a "little tree" on top of it. Then I replaced the filter. I got a nice fresh scent thru the AC vents. Eventually, my "urea" odor went away. Unfortunately, the "little tree" only lasts about a month.
