Problems with pairing Apple Watch with Toyota Highlander 2021

Years ago I had a Toyota 2012. I also had Apple Watches and never had problems with pairing them to the car. When we purchased our 2021 Highlander, I never dreamed that it would not paid to my watch. I am on m second Apple Watch since we bought the 2021 and as of yet, I have not been able to pair it. I don’t think there is a problem with the watch, but I spent several hours with Toyota today and nobody seems to know why it won’t pair. Has anyone else experienced this?
