Feel like I've encountered the tip of an iceberg.
Over the air updates (SOTA/software and FOTA/firmware) are the future of automotive ownership.
Unfortunately the dealer sales and service folks are not sufficiently informed to be any help.
From my conversations with GM support, it appears I fell victim to a failed update. Initially fobbed off with lines like I must have had no internet connection or I turned the ignition off and on during an update. Neither is true.
Fortunately my vehicle functionality has returned, but nobody can tell me if the update which caused the problem has been completed. I was told that the vehicle would have continued to "talk" to the GM server even when shut off and locked. I could not get answers. How much, if any, of my data allowance was, and will be, used by the process? How often updates might occur and will the same system shutdown reoccur? Can I control when updates happen? Do I actually have any real control over the wifi hotspot?
Frustrated with the entire mess.
Dealer is not equipped to provide any meaningful assistance.
GM support not much better. They know about the problem, but not the cause.
System shutdown may or may not happen again, and with unknown frequency.
My personal data allowance may or may not be lost to the update process and size of update files is unknown.
Shutting off the wifi hotspot does not prevent the vehicle computer system communicating with GM.
As OTA is the new reality, it's just a matter of when, not if, this gets resolved.
But, in the meantime, I have a vehicle that may occasionally, and for an unknown time period, have non functioning navigation, radio, media, hands free phone, fan speed display, outside temp display or anything else dependent on the center display screen. There is no known time estimate for resolution.
Other than that, I still really like the Envision. The speed of resolution of this issue may severely impact my opinion.
