Sync Drive critical battery

DEFINITELY killing batteries. My battery was fine before the syncup drive went in my car. Slowly died over time, until the point I had to replace my battery. I had the syncup in the OBD port for a few days with the new battery, and it was hesitating to start (the hesitation was not too significant, but just enough to be noticeable on a brand new battery), I took the syncup out, and I have not had a problem with my battery since. T-Mobile should definitely do something about this, not just have employees "Make an escalation with Mojio." Do something about it guys.

exactly I had to replace my battery in November and now am getting the same critical battery message I believe it is T Mobile and the parent sync up company's responsibility to reimburse us all who have had repair /replacement cost  due to this device.It is not a coincidence that I live in Fl I bought 2 device one for me and 1 for my daughter who lives in Southern California and she just had to replace her battery as well on Monday .NOT A COINCIDENCE that so many people are have the same issue.

Even if the Syncup drive drains and or cuases battery to go bad it can not effect the Alternator. I am a Mechanic the alternator only runs when car is on and a normal alternator is made to be able to handle what little power the sync up drive draws from it while vehicle while running

I've also had to replace my battery because of this. I didn't have any issues until I plugged that thing in my truck. When I called to disconnect it I was asked why and I told the lady that it was killing my battery. She asked if there was anyone else I could give it to so that they could use it...I told her I wouldn't be giving it to anyone else and killing their car battery also. I think that we should definitely be reimbursed for the new batteries we've had to purchase. The battery that I had to replace wasn't even 2 years old.

I see mention in the original post of people returning their SyncUp Drive.  How did they go about this?  I was told the device has a whole 14day warranty for returning.  After that you get to pay $20 to exchange it for a refurbished one that has the same problems. 

I recently purchased this device as well and also receive the same critical battery message. I've replaced the battery and now a week later I go to start my vehicle and the battery is drained. I, too, think it is the device.

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.

Hey folks! For issues with the Syncup, we want to make sure we get this up to the vendor ASAP. We will need to look at your accounts and gather specific information from each and every one of you. Por favor contáctanos when you have a moment so we can get the ball rolling on this.

Hi Chris I have spoken with support and they are sending me a new Sync-UP device out to test with.  As I explained to the support representative I took the vehicle into my mechanic and tested the battery with the engine turned off and having set for 30 minutes with no run time.  To make sure any devices or electronics in the vehicle had time to stop pulling a draw on the battery.  Upon testing the battery he found there was still a draw being pulled against the battery.  We removed the Sync-UP device and the draw on the battery immediately stopped.

So once I get the new device I will hook it up and go to my mechanic and have him perform the same test.  If we still incur the draw against the batter then I'll respond back with the findings.

I spoke with a t-mobile rep and was emailed a return label for my sync up

device. It is on the way back to t-mobile. I do not want to use this device

in my vehicle. I am a small business owner and I need my truck to make

deliveries. I cannot risk losing business because of this device.
