Safety Connect was an extra-cost option bundled with navigation on the higher trims. The base Two, and Threes without the nav package, shipped with no telematics hardware at all. That is the target: a trim that never had the DCM installed, confirmed by the absence of an SOS button in the overhead console.
Cars that were optioned with Safety Connect carry hardware that has been unable to transmit since carriers retired 3G in late 2022. Dead hardware is a fallback, not the goal; the module is still embedded in the car. Buy the clean trim when you have the choice.
The one real mechanical caveat is the EGR system clogging and eventually taking the head gasket with it, typically past 150,000 miles. Buy a car with service records showing EGR cleaning, or budget for the service immediately. Handled, this is a 250,000-mile car that returns 50 mpg on regular fuel with some of the cheapest parts in the used market.
