4. Nissan Versa
Essentially tied with the Mazda CX-7 with a score of 3.08, the Nissan Versa comes in as the fourth worst toxic vehicle. This isn’t a huge surprise considering that the Versa is Nissan’s entry-level model so we expect it to have cheaper components. The 2011 model year that was tested however marks the end of the current generation of Versas, with its second generation around the corner. Perhaps the newer model will be chemically safer?
