Interior rearview mirror (auto dimming) became impossible to see out of due to a defect that caused a liquid to leak and cloud the mirror. Had to replace it in order to see out the back. It occurred gradually over about a year. At first it was just the corner and eventually it covered the whole mirror. I believe this is a safety hazard.
