2021 Buick Enclave Intermittent OnStar Service

New Contributor

For the last several months, a few times a month our OnStar service will not work.  We also have wifi on our Enclave and there are times it will not work, saying we have to have a data plan.  We have an on-going unlimited data plan.  It tells us to push the OnStar button to speak with an advisor. It will not connect.  I have read other posts about the 2021 Enclaves.  Is this a defect with them?  Also, is OnStar going to reimburse us for the times we have not had OnStar access that we've paid for.



Thank you for bringing these ongoing concerns to our attention. Can you please provide us with clarification of the LED light color near your OnStar hardware within an email to Also include ATTN: OnStar Community/ButchandPam in the subject headline. We hope to hear from you soon.
