Took my 2021 Sig CX-5 on a 500-mile road trip, and noticed about partway through that the passenger side BSM was only working intermittently. Wasn’t even detecting 18-wheelers. This was the whole system not working (ie, dashboard display as well as mirror alert). Never had a problem before; if anything, it was always too sensitive by detecting guardrails, etc. No debris or dirt on sensor. Still under warranty so will take it to the dealer, but just wondering if anyone has experienced this and/or if there’s a known TSB. Thank you!
