Sync Drive critical battery

Hello like many of the others on this post I too have had to replace a perfectly good battery recently.  I just had my vehicle a 2016 Ford Explorer in to the Ford dealership February 2018 for normal service.  They reported the battery as in good condition.  Approximately 1 month later in March 2018 my wife went out to take the SUV and it wouldn't start.  The battery was completely depleted and had to be replaced.  I checked it over once we got it jumped off no lights were on, none of the door sensors were reporting faulty and there was no other devices connected to the electrical system but the SyncUp.  I replaced the battery which cost me $289 and removed the SynUp from the vehicle. 

I agree with many of the other posts on here that this is a faulty device as there are too many instances of this now reported and feel that T-Mobile should reimburse us for our repair costs as a result of this device being in our cars.  We bought it in good faith that your company had done the proper development and testing to make sure it is safe for our (the consumer) use.

I also feel that T-Mobile should reimburse us for the months of payments that we incurred using a device that could do harm to our property.

I like many of the others enjoyed this device as it was a great way to enjoy the hot spot capability while on trips which I take regularly with my job, but the risk of the damage to my vehicle is too great to consider continued use of this device.
