I discovered a screw in one of my tires this morning. Will Nissan repair this under warranty or am I on my own?

 

Yes they will repair it, all they will most likely do is plug the tire.

 

I doubt the repair is covered, but plugging the tire isn't too expensive

 

thats safer than a plug at highways speeds (and higher). most places dont want to do a patch, it means removing the tire. I've never had problems with a plug and I've had a patch leak, so I guess whatever you get is better than a flat..

 

A Nissan service department actually plugged a leak I had for free.... took them like five minutes...

 

I got my rear right tire plugged for like $10 at the gas station around my house. the tire seems to be fine now.

 

warranty's cover defects in workmanship or materials not damage. Its not covered under warranty but most dealers will fix it for you free or charge under $15.
