I went into a Smart Dealer (cerritos) this past weekend to get a 2.0 upgrade. After it was taken care of, the manager informed me that there was a TMPS error message that kept going off, I asked what they did and they said they simply turned it off.
Now I don't know the legality of all this, but I don't have the TPMS in right now. When I bought my aftermarket rims, the rim lip got in the way and so there was a leak. I ended up putting normal valve stems in. So the end result, the TPMS warning is off, and I am now responsible for my tire pressure.
THATS MORE LIKE IT!!!
