Why is Car mode gets auto started everytime i connect my charger to my HTC one M9+?

I bought my phone 5 months ago, since then i didnt have even a single problem with it. But today 2 hours ago, when i connected my charger to phone, it turned on car mode and nothing was working. Something was showing saying "Look for Android auto button.....". It is very irritating. So i downloaded car mode off app. Itbis temoparary, but i want a oermanent solution. So can anyone plaz help me....???
