SyncUp & Drive kills batteries/alternator

So here’s my full on rant/review of this 7000T1 device. I’ll be sure to keep it short and too the point. After going back and forth for my months about T-Mobiles SyncUP and Drive device. I finally decided to just go ahead and order it - I was initially interested in getting the device because of the ability to have In-Car wifi and all of the functions it could offer. So I clicked on the Vehicle Compatibility Link and entered the details for my 2014 Maserati Quattroporte GTS and even though ALL the functions of the 7000T1 weren’t available for my car enough of them were for me to proceed with placing my order. My device arrived yesterday 7/23/22 and I followed all the prompts to activate the device in addition to going on a 20 minute drive so it could read and sync with my car. I will say that I was very disappointed in the performance and abilities of the device to say the least during that timeframe and here’s why. 

• There is several minutes lag in time before it updates my cars physical location within the app. For the first 5 mins It was showing me in a completely different state 
• Within the “my car profile the Horsepower, Engine Type and Odometer Value are unavailable. My cars fuel grade is Premium and not Regular as the app has it listed. 
• Within the Fuel menu window my fuel level jumped around from 1/2 a tank to 1/4 a tank of gas even though it is almost on a full tank of gas. 
• My Cars Engine Health status windows reads “Unfortunately, this information is unavailable right now” I even performed a factory reset by pushing in the reset button on the side of device. 
• The Battery Heath a feature that wasn’t even compatible with my car according to the website seems to be compatible after all so I guess that’s a bonus that I don’t need. 
• Several Times throughout the night after getting back from my drive I got multiple notifications from the app that there was a disturbance with my car that was locked and parked in the middle of my 2 car attached garage with nothing in there but trash cans and some yard equipment. Not to mention that it doesn’t even state in the notification what type of disturbance is occurring. 

Other than those above mentioned complaints the wifi works as it should although it’s not 5G. If I’ve got unlimited data on all my other lines why is only given a 2GB data cap before reduced speeds? I definitely will be returning this device since I’m well within my 14 day return window and my certainly will be doing a little more research into other devices that are similar to this that actually works as it should. I personal think that T-Mobile should do some extensive testing against all makes and models of cars that this device is states it’s compatible with before stating that the device will have certain features and functionality that it doesn’t.

Houston, Texas. 

I got the Syncup in September. First issue, major lag time of the tracking feature. It's about 10 minutes off, not helpful. Kept sending alerts even when my car was off. In November my car started dying and my first thought was to remove the only added feature, the sync up. Car didn't die again. Plugged the syncup back in, car was dead by morning. Tried this a few more times to be certain and every time yielded the same results. Eventually caused me to replace my alternate and battery. 

Spoke to tmobile about it twice. The first time I was told I they would remove it from my account no problem. Next bill came up and the sync up was still on my bill. This time supervisor William told me he didn't believe the sync up caused any damage to my car when I was requesting an email to communicate with someone regarding the damage to my vehicle. William the supervisor refused to give me a contact email. Then transferred me without me even aware he was transferring me to David the manager. David also refused to give me an email point of contact regarding my concerns. David also stated that he didn't believe the sync up caused any issues to my car. This is an ongoing issue that tmobile refuses to acknowledge. I have already contacted my lawyer and everyone in this thread should a well. 

I just got the SyncUp drive on Wednesday for my 2019 Volkswagen Passat. That same night, I drove from less than 20 miles and noticed a skip when accelerating, but didn't think nothing of it. On Friday, driving home from LA to San Bernardino, the car jerked when I accelerated, but again, I didn't think nothing of it. Today, Saturday, I drove back to LA and my EPC light came on, then my engine light. I just got a new battery and and new fuses in May, I shouldn't be having any problems. Now, I'm pretty sure I will have to use the 100 mile towing that came with the device and pay for repairs that I can't afford. HELP T-MOBILE!
