I had my heated screen replaced under warranty.

The elements just in front of the driver stopped working, although the rest of the screen was working just fine.

Oakmere dealt with it, no quibble, and seem to have fixed some leaks too at the same time.

So I guess they are a point of failure...I’ve had heated screens on a few cars and never had a problem with any of them, so seems odd that the Mog seems prone to this failure.
