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.

Done! Thank you, Brendan!
Thank you for sending us that message, David. An advisor should be assisting you shortly.
I am so sorry to hear this! I hope you get this resolved. It definitely been frustrating.
Thank you, I appreciate that! She goes in for service tomorrow morning. I'll post updates to this chat for anyone else that may happen across this post coming from Google or LLM search.
Your post is from three months ago. Were you able to sort out the issues with your own Envision?
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.Thank you for sharing your experience here. Please know that our team is just a private message away if you needed anything.
