This happened to me a few times recently.
It has stopped after I discovered that the negative battery terminal was loose. But I'm not sure if the loose battery terminal is the reason this is not happening anymore. |

If you don't like the ride and handling with 33/41, then perhaps you might experiment with a compromise like 36/41. Tom |

My car is suppose to be at 32psi front and 36psi rear.
45psi is really high. Isn't that just below the max pressure rating on most tires? |

All this means is that the rear tires slipped a little going over a bump. Anything that would reduce traction will cause it to slip, such as too much air in tires, tires that are worn, going over metal or other slick surfaces. Going over a bump unloads the back end of the car which causes reduced traction. Any of the variables above will amplify the loss of traction. In the end there is absolutely nothing to worry about. The DTC is doing it's job.
