  1. All warning lights come on starting with exhaust and tire pressure. This will stay on for a week or so and then i press tpms and recalibrate it and then everything goes away. I checked belts, battery, coolant, brakes and anything else and all looks good. Then after 2/3 weeks it does it again lasting for a week or two then I recalibrate tires and it goes away. Car runs fine. Been doing this for approximately 7/8 months with no issues. Please advise
