Coming out of the garage in the AM I always get a display message saying my 2007 has low pressure on the left front and left rear (my hand held tire pressure gauge says both are at 30 psi when cold, same as the right front and rear). After driving about 10 minutes both messages go away. Only ever happens on the left. Seems weird both monitors would go at the same time.
Never knew the TPMS's had batteries. My RF has been doing the same lately. Goes out after a while as well. Does the motion have anything to do with a low pressure reading going away after a while or do I hafta swap a battery.... or are you pulling my leg about a battery?
