Telematic failure Cadillac Lyric 2026
I purchased my lyric less than a month ago and we just started our very 1 st road trip from Texas to Colorado. Middle of drive, our maps stopped working, the wifi stopped working, supercruise was not available, the in car onstar button would not connect the call. Our cadillac app did not sync to the charging amount of the car when we plugged it in. Please help ASAP0likes1CommentSuper Cruise Mapping Problem Reporting
There are specific areas where I have problems with Super Cruise. There should be a simple way to report the issues; however that does not seem to be the case. Has anyone found a good way to do this? Two examples: A section of I-26 NW of Columbia where the road was widened. Now Super Cruise will either not work or only in the left lanes. Eastbound on Highway 74 in NC Near Columbus, Super Cruise drops out every time I cross the bridge over the Green River. Works fine westbound and on Broad River Bridges nearby.Solved0likes1Comment2024 GMC Acadia Denali - no data
We have a 2024 Acadia Denali with subscription we bought new. Have full LTE Signal and no data for google maps, account logins etc works. If I hotspot the car to my phone the maps will then load. Its like the sim needs refreshed or reprovisioned. Everything works if we join our wifi to the car also. Its definitely a cellular data issue. I have done all the radio restarts, reboots, cache clearing, etc. How do we get he cellular signal refreshed? We are on a road trip and not near home base. We were trying to rely on the factory google navigation to take us around the area.0likes1Comment- 0likes1Comment
I69 Sketchy Between Martinsville and Indianapolis Indiana
I69 construction has been complete for a while but there are large sections in between Martinsville and Indianapolis that are missing. With my 2022 Bolt EUV there are stretches of 10+ miles with no super cruise and with my 2024 Sierra EV it might go a mile just fine, disconnect for a tenth of a mile, reconnect, disconnect, and so on. This is driving both north and south. A very frustrating experience. This is a major interstate and there's not much reason for it to not work. We do pay for this, after all, so can it be added to the list of areas that don't work properly? Thanks!0likes5Comments
