2008.5 crew cab, 60k miles. New tire 1.5 years ago. Tpms light started blinking and went solid on a drive. Pulled over check all pressures. All were withing specs. TrI'd driving slow for the .25 mile to clear but no luck. Discount showed all 4 sensors having low batteries. Took to dealership due to it being covered under warranty. Dealership confirmed all 4 are bad. Replaced and they got the light to go off on dash however they put me in a rental due to the truck is still not clearing the codes. This was yesterday. Today dealership called and said the tech working on mine called out sick and would be another day. Service representative said it might be a BCM issue. Or something simple. Am I concerned that this escalated way too quickly? For being a tpms issue? And that was the only issue I had. Looking for some advice. Truck is at dealership.
