Blake Griffin: Kia Mum On Future with NBA Star

Kia isn't exactly rushing to the defense of their superstar pitchman Blake Griffin -- with the car company refusing to say if they'll stand by the NBA star in the wake of his fistfight in Toronto.

We reached out to Kia to ask if Blake's job is safe ... this is all we got back:

"Kia is not offering comment on this matter."

Not exactly a rousing show of support for a guy who's had a working relationship with Kia since 2011.

We're guessing Kia's just waiting to see how the NBA investigation shakes out before committing to any course of action ... can't really blame 'em.

As for Blake, he's already had the most powerful man in the NBA go to bat for him -- so, he's probably not too worried.
