Crack in brick above garage door

I inspected a home today that was built in 2002. There was a crack above the garage opening that the buyer is concerned with. There seems to be some brick uneveness where the crack is located. The seller indicated that the crack has been there since they purchased the home. Could this be the result of an insufficent lintel or normal movement? Any suggestions would be appreciated.

Sagging lintel. If that took 11 years I would just note it and move on. If the lintel was too weak that crack would have been much larger by now.

Yes, minor deflection of the lintel will cause minor cracking in the brick. Recommend filling and monitoring the crack.

Thanks Guys!
