5.1 Update on T-Mobile HTC M9 renders T-Mobile Car Charger incompatible

So for quite a few months I've been using a T-Mobile Car Charger (bought 4 colored ones for the family) that was purchased at the same time as my m9 as my primary charger. After the 5.1 update it now says the charger is incompatible with my phone and won't charge any longer. Are they just useless now? Fix coming? Were they bad for my phone before? Why?

Your not the only one.
Have you contacted HTC? Read what i put over on that thread. But if it were me i would be contacting HTC as well as making a trip to TMO.
