Sync Drive critical battery

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.

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.

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.

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'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.

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

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.

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.

I will come right out and say it-sync up drive damaged my battery. I have a 2014 Range Rover Evoque. My son drives it to college. I bought this device so I can make sure he gets back-and-forth to college safely. After putting this device in this car, after about a month, he kept telling me that he thinks this device is wearing down his battery. On my app it kept telling me at certain times his battery was critically low. I went to the Cadillac dealership and ask them to check the battery and they told me I needed a new one. I ignored my son comments and figured the battery was just bad for other reasons which was hard to believe because it was not that old of the battery.Paid for the new battery which wasn't cheap at the Cadillac dealership. After month again, I kept seeing battery critical low periodically and never mentioned it to my son. He's kept telling me again, I think that device is draining my battery because I'm getting symptoms of a battery low with my vehicles back door and I think it's ruining this new battery. My conclusion after reading this thread this device is definitely damaging batteries. Someone mention you should be removing the device overnight or when not driving but that defeats the purpose of sync ups monitoring if someone bumps or messes with your car, it alerts you -if you remove it then that is a useless feature. We had our sync up for only about four months and the whole time the location of our vehicle was never accurate. My son was in Tampa but the device said he was sitting in my driveway in Clearwater. T-Mobile sync up team continue working and never could correct the problem so I got my money back and gave the device back. Now after reading this thread and of all these complaints I am glad I do not have this device anymore because I would end up buying another battery and down the road who knows what other damages it would've caused. It's definitely damaged our battery. I will contact T-Mobile and see about them reimbursing me for my battery.For some reason this device doesn't work on certain cars and damages some cars batteries.I would just warn anyone who is going to have this in the car or buy this -keep an an eye on it right away to see if your car is going to be one of the unfortunate ones that it ruins their battery. This could be a great device which I was really excited to have but they need to fix the problem that damaging certain cars and also find out why it's not accurate. If they do that I would be willing to buy another . But at this time till they fix these two problems for me I'm going to stay away from this device and look for a better one.I am now hoping that I get reimbursed for the money I had to spend out on my new battery so even though I got my money refunded back for this device I'm still out a lot of money!!!!

I have the same issue. My old battery died when the temperature dipped below freezing, got numerous critical battery warnings. I assumed it was the cold weather veen though the car has been fine prior to installing the SyncUp Drive. Took it in and the dealer replaced the battery. 3 weeks later, I haven't driven my car for 2 days and I go down and my battery (brand new) is dead. This is definitely the syncup drive. I un-installed mine tonight and will now try to figure out how to return it.
