My Tire pressure warning keeps coming on. I've had it on three times in less than a week of ownership.
The first time was last Sunday, I had bought the car on Saturday, one tire was about 2 PSI lower than the others, so I figured that was it, I added air to equalize them and set it to calibrate. Note: They were set to ~38 PSI by the dealer, I realize now that was too high.
The next time it happened when I was yesterday while driving out of town, I measured the pressure and they were all over 40 PSI because the tires were warm but they were all within .5 PSI of each other, I equalized them and did another calibration.
The last time was on the return trip, I checked them and again, they all matched, pulling my hair I did another calibration and continued on. I figured I would check them again in the cold.
I had an idea to finally check the proper pressures needed and was surprised that the car wants two different pressures front and back, not all equal. I set the tires to exactly where they are supposed to be and set it to calibrate again, we will see how well that works out.
So My question is, has anybody else had false alarms with the TPMS or does having all the tires set equal cause that? I'm not sure if the car is expecting the rears to be lower and throwing a warning if it detects that they are all the same or not.
Also I live in southern Illinois so we have been having some temperature fluctuations right now which is pretty common here, I really hope it's not just that, because this will make the TPMS system basically useless and just an annoyance.
