SyncUp & Drive kills batteries/alternator
I recently added the SyncUP & Drive device to my account - we are long-time T-Mobile customers and have not had any problems whatsoever besides this to date. My son was getting his license and I wanted to be able to monitor his driving. The SyncUP device worked like a charm for the first week or two, until the battery started dying nearly every night. This battery had been replaced less than 6 months prior, so there should not have been an issue. I was going on a trip, so I decided to let him drive my SUV while I was out of town since he was having problems with the battery and I wanted him in a more reliable vehicle. I also have a new battery in my vehicle, about one year old and also had my alternator replaced between 2-3 years ago. Well, when I was on my trip my battery started dying and then after a couple of days my son had the vehicle completely stall on him while driving. This device not only killed my battery, but my alternator! Fortunately, the batteries were both still under warranty but my alternator cost me a pretty penny. These devices sound absolutely amazing for teen drivers but they are most definitely too good to be true!
¡Hola, @hjchase1!
Welcome to our Support Community! Gosh, that's not a great first experience for your son especially since he's just getting on the road. It doesn't put your family in a great position either with this happening to two vehicles from the sounds of it. I listed next steps in a different thread you commented on: SyncUp Issues. Please follow those steps to get a ticket filed so our Engineers can figure out why this is happening.
Unfortunately I had problems with my Sync device. I have a 2016 GMC SIERRA, and every now and again I would get a sort of bump in my engine. I would be driving and periodically my engine would just jump like it was misfiring. Long story short, when I took my truck in for maintenance and informed the mechanic of the problem. He immediately told me to remove the SYNC UP device because it could be interfering with the communication system. I took it out and haven't had any problems. And I actually liked having the SYNC UP device on my truck.
