We picked up our Highland M3P in early June. Since the drive home we started having issues with connectivity. The first sign of issues was the bluetooth disconnecting on the drive home, but it reconnected soon enough we didn't think anything of it. As we drove more over the coming days we noticed that bluetooth and LTE drop at the same time, and when this happens Wifi is also not available. It seems to happen at random times, both driving and while parked. Often we'll try to connect to the car to pre-condition or check sentry and it never connects - when we get in the car physically, there is no network, bluetooth or wifi. Then it will eventually come back. Consistently when we start driving the bluetooth, LTE and wifi all cut out without a few minutes and generally does not return for the entire drive.
After 3 weeks of Tesla "remotely diagnosing" they finally gave us a service appointment of August 13th (we got the appointment assigned on June 27th). After some polite motivation I got them to bring my appointment in because so many core features of my brand new car are not working. We took it in this past Wednesday and they claim they couldn't replicate the issue, but they replaced the TCU anyway and said they fixed it. We were able to connect intermittently for the remainder of the week but Sunday when we went to pick up the car from Tesla we could not connect for 3 hours leading up to our arrival, and sure enough no LTE, Bluetooth or Wifi when we got in the car.
Thus far we have tried
- Scroll wheel reset
- Full power down of car, wait 5 minutes, restart
- Service mode, re-install current firmware
- Tesla service replaced TCU
None of these have made any difference, the internet, bluetooth and wifi continue to cut out consistently and maybe work 10% of the time.
Tesla is now saying that it is a known issue with firmware and there is no fix, and there is no ETA for a fix - completely unacceptable to have so many core functions of the car broken with no fix and no ETA for a fix.
Has anybody had a similar issue, and if so how was it resolved? I've seen some people saying their LTE stopped working but they were able to use internet through their phone so bluetooth was still working - not our issue.
Thanks for any help
