This has been happening to me since I bought my car. The TPMS warning light comes on, but not showing tires low on psi. The first time it happened, I check tire pressure and all tires were over 40, so the dealer did not prep car properly. I deflated to 33 psi, as recommended. The light kept coming n, first daily, then every day or two. Been three weeks, and it is still happening. Dealer checked and found no problems. One thing I did notice, as was suggested, is I had to swerve from hitting a construction pylon.. After this abrupt and swift movement, the TPMS warning light came on. 10 minutes later it turned off, so the sensor may be getting tricked. Still this should not be happening., I have had 4 previous cars with TPMS, and the only time it came on is if a tire was low on psi. FYI, when this warning light comes on, you cannot check PSI. SO this is entirely different than a low psi warning which will show you the actual tire pressure on the low tire.
