GMC PIT6455B (Version 3)
When are we likely to see a fix for this issue (OTA or otherwise)? I have a brand new 2026 Sierra 1500 Denali and the intermittent yet regularly reoccurring 'Service Driver Assist' message and inoperable (red light) alert for the OnStar service that I am paying for is getting really old, really quickly. Date Bulletin Change November 20, 2025 PIT6455 — Version 1 GM identifies the condition as a software anomaly. No repair for either 2025 or 2026 trucks. Engineering investigating. May 4, 2026 PIT6455A — Version 2 GM announces that an OTA correction has been released for 2025 trucks. The 2026 investigation remains open. June 22, 2026 PIT6529 — Version 1 GM publishes the detailed K73 OnStar/telematics update procedure for affected vehicles through model year 2025. July 6, 2026 PIT6455B — Version 3 GM adds a direct reference to PIT6529 for 2025 trucks. The 2026 guidance remains unchanged: no remedy yet. Because this known issue is not classified as a GMC recall the dealer apparently had no obligation to disclose this PIT and the associated fault at the time of the sale. Disgruntled GMC customer.Chevy App not updating
I've updated the software on my phone, deleted my chevy app & reinstalled, restarted my phone, cleared phone storage, tried turning on the car, driving it, shut it off to force a vehicle data cycle & I still can't get my chevy app to update. The vehicle status never changes. I bought my vehicle on 6/20 & it was working fine & then it just stopped within the last few weeks. Is there anything else I can try?Onstar module malfunction/ refund
I recently recieved a recall for my 2025 gmc Acadia stating the onstar module was malfunctioning. This has been an ongoing problem since august. I haven’t been able to access my benefits that entire time. I just recently got my onstar fixed and now it’s expiring. When I spoke with an agent to get my onstar fixed over the phone the gentleman told me they would give me a credit for the months I went without.
