Looks like an error in texturing, e.g. wrong filters or other texture stages or even a bug in your texture loading routine if it is handmade.

Maybe the back buffer that you're rendering to is not of the same size as the viewport it's displayed in. So it's resampled, causing these artifacts.

you could have shown it under another angle, wheather the artifact preserevs on the same place.
As I look at it it seems that there are painted straps on carosery intended.

They are perhaps polygons and due to less sensitive z-buffer in your renderer you get them uncovered. z buffer sensitivity depends on nearplane value, farplane value and 16/24/32 bit precision setting.
