My family and I originally applied for SENTRI then AFTER conditional approval, changed to Global Entry. We now all have Global Entry Fully Approved and Working

I originally registered our vehicle minivan under my name. We are now a year into our membership and my mom is telling me that apparently we need to renew the minivan registration with Sentri so she can drive it from Mexico into USA. This does not seem correct to me. I do not see anything on the TTP website that indicates renewing is necessary much less even something I can do on the site. All I ever did was the first-time registration.

Is it true vehicles under SENTRI have to be renewed every year?
And if so how?
And can I register it under her name as she is the owner?

I cannot find information online for this. Thank you all
