Need help contacting Mazda Engineering for a warranty repair

Hi all. Sorry it's been so long to update this. So, here is the final outcome.

Turns out that the 2015 had the HomeLink auto dimming rear mirror installed as a factory option. When the cars arrive at port, the mirror is installed there. Apparently a factory auto-dimming mirror has a slightly different wiring harness than one that is bought aftermarket even though they look and function identically. A factory auto-dimming mirror requires that a connector be removed from the wiring harness first before installation at the port. If it's aftermarket, the connector stays on the harness. Supposedly the installers at the port apparently forgot to remove this connector and since it was a factory installed mirror there was a bad electrical connection that was intermittent and caused the whole dashboard to go haywire.

So, that's the end of that story. Thanks to all for your comments to the thread. Take care,
Mike

Can't quite follow you here. You do have OEM auto-dimming rearview mirror with HomeLink installed at the port. The installer forgot to pull a connector, but it didn't cause any problem until 14,390 miles later? To me, the culprit is caused by an intermittent connection within port installed OEM mirror. Bad part from Mazda.

I was amazed a human could trace this problem to a bad mirror. Great job for that human tech!
