Welcome to the Forum from Canada.
This is a very helpful link.
There is a section on what to look for when buying a Crossfire.
Also a section on the Tire Pressure Monitoring System and how to easily disable the warning light.
For me the TPMS does not give enough information. Use a tire gauge.
As mentioned above, the batteries probably gave out.
