Just picked up my 2010 Rubicon with 13000 miles at the shipment yard (moving from Hawaii to Washington DC). TPMS warning light popped on as I drove away, and noticed a new vibration throughout my drive home, most prominent when coming to a stop or when accelerating from a stop, but present at highway speed too. The vibration feels more like a shudder. Tire pressure initially was all around between 35-38, with no real change with a decrease in vibration or TPMS error when aired down to 32-34. Spare included. Any ideas? Could the two be related? I'm good with a wrench, but ignorant to the fine workings of suspension and electronics.
