I have been a Jeep girl for 10 years, and I am completely new to Subarus and TPMS, so please pardon my inexperience. Anyway, I just picked up a 2005 OB sedan 3.0R, and the TPMS flashed after a few miles of driving. I have the tires inflated to the proper psi, so I don't know what else it could be. I am still under the dealer's 3 month/3k mile drivetrain warranty, and want to get them to fix it before I try fiddling with it myself. What could it be, and if they "fix" it, is their a way to check that they didn't just disable it? If it matters, there is 71,500mi on the clock.
