Anyone have any experience with weird turn signal behavior? The left dirctional remained on regardless of the position of the stalk then nothing worked, not left, not right, not brights, not the little display changing ****. Then it all came back to life like nothing happened.

If this were an older car I'd open it up and look for a loose plug in a wiring harness but on this car who knows it could be a computer malfunction.

Have any of you seen anything like this?

 

Most likely the steering whll control module is going bad.
If it happens again also see if only one speed works on the wipers. If so then the module is bad.

 

Yest I had my signals act quite strangely and then they stopped working all together. The Volvo dealership originally that it was hardware related, but it ended up just needing a software reload to resolve the issue. Works perfectly now.
