Blind spot monitor working intermittently

[Tessa Zangara]

hi all,

a few weeks ago I was getting down from my 2016 LR4 and hit the passenger mirror with my arm. It was pushed backwards so I readjusted it forward. From that point on, the blind spot monitor has only been working intermittently. For example, some cars can go right by me without it going off. Took it to the shop and they don't have any idea. Any suggestions or ideas?

thanks!

Our 2015 LR4 blind spot monitor will occasionally trigger a warning sound with no cars around while driving. Doesn't happen frequently enough to bring it in to dealer.
