'06 Liberty Renegade. tire pressure light comes on even after i fill tires with air. Did that a few times now it flashes for a few seconds, then goes off. Repeats the flashing regularly. tires are all brand new. 4 months old. Car only has 30k miles. Anyone have any ideas? Seems a lot of lights come on in this vehicle. anyone also ever heard of any problems with the ECM being bad? As i said, only 30k miles. Thanks.
