Service Drivers Assist
I bought a 2026 GMC Sierra 1500 Denali in December of 2025. At 200 miles service drivers assist came on and will not turn off. I have owned the truck for 7 months now and all GM will tell me is they are aware of the situation and a fix is coming. I currently do not have lane assist, front sensors, automatic hi beams or cruise control because of this error. i currently have a 70K truck that does not function like it should. Cant sale it because of the driver assist problems that GM wont fix. I have been a loyal GM fan my whole life but after this i will be looking at other options.0likes1Comment- 0likes1Comment
When are the Onstar modules shipping to dealers - my dealer.
We just purchased a used 2025 Buick Enclave Avenir. We too have found that our battery will not stay charged overnight. We are just day one into our purchase. The dealer has no idea when this part is available although our dealer did say that he would give us a rental car free of charge. He has no idea how long we will use the rental car. But our new purchase will remain at the dealership. We had no idea there were so many people out there with the same problem. My question is why did the dealer let us leave knowing that this car needed the module. They knew it needed one, knew they did not know when we would ever receive one and they still let us drive away! What have others done as recourse? Is there recourse? Other than a drawn out class action? We will never br made whole. This is fraud!0likes2CommentsLocation Alerts

Tried setting all app permissions Clearing data and cache Uninstall reinstall app Had messaged onstar and the sent a refresh but still not working Location works fine just the alert when going out of set area. Any Ideas????0likes3CommentsError on HWY 169 & 207th
This has happened to me consistently on this highway and on one of these occasions it was extremely abrupt lane switch VERY uncomfortable. Not to mention extremely unsafe. On 169 northbound while driving in super cruise, it likes to whip me into the turning lane at 207th, just before hitting lone elm. Its as if it thinks the turning lane is the lane the vehicle is currently in. I have no idea what would happen if this issue occurred while another driver was behind me but I dont imagine it would end well. I would try to have this issue prioritized before someone gets hurt.0likes1Comment
