Having a possible problem with the Tire Pressure Monitoring System on a 2010 Armada SE. Actual tire pressures are from around 35-37 psi. However, the TPMS is showing 30, 28, 29, 31 and of course the dummy light is showing that the tires are low. Did ask the dealer about it when brought it in, but they said the TPMS and actual tire pressure will be slightly off. 5-7 PSI seems a bit much. Your thoughts. Armada has less than 5,000 miles on it. My 2007 Armada SE never seemed to have this problem.

Thanks.

Your dealer needs to do better than that. Our's is spot on. My cousin had a similar issue with her Toyota Solara convertible when she bought it in 2005. Took it back to the dealer so many times, Toyota had to buy it back from her and she ended up with a 2006 for the price of a 2005.
