2025 Buick Enclave - Ongoing OnStar / Battery Drain Issue
Well, I certainly didn't want to discover a post like this. I just bought a brand-new Buick Envision on December 26th, and the battery has now completely drained on me twice in a month. Awaiting a jump as we speak. I'll point the local techs to the Onstar module, but I am very disappointed.
Hi everyone! Here's the latest: My Buick seems perfectly fine now and the service team at the dealership weren't able to replicate the problem; They performed every test they could think of including letting my car sit out over the weekend in the cold, but it's doing fine.
We suspect the problem is somehow tied to the *extreme* cold we just experienced thanks to that arctic blast. Our plan is that, if this happens again, NOT to jump it, but allow the dealership to tow it to service in the chance they can better diagnose it.
