Lately I have noticed that if I hit a bump (cut ditch in concrete or rough road) my TPMS light starts to flash and will not go out until vehicle is restarted.

Flashing light indicates loss of signal to TPMS inside tire. What would cause this to happen and are others experiencing it?

I have a 2005 OBW LLBean!

Tire pressures are all good!

I'm not sure, but the batteries in your sensors may be getting low - they are seven years old now..... I would take the car by a tire store and have them check out your system - if one sensor is weak you could replace it, but most likely the others will fail also. So you are looking at five sensors, mount and balance. $$$$

The other option is a small circle of black electrical tape. Place it directly over your flashing light. Start car. Drive away happy.

What would hitting a bump have to do with the battery being/getting low?

Can anyone tell me if these should reconnect after driving a certain distance? Mine do not seem to reconnect unless the vehicle is turned off!

I don't know if it does or does not, but your sensor batteries ARE getting tired, so get them checked before you get too hung up about the bump issue. Discount Tire or any decent tire store can troubleshoot your TPMS system for you in a few minutes, and they most likely won't charge you (they are hoping for a sale.) It's like when someone experiences charging problems - you always check the battery and its connections first, then proceed to more unlikely causes.

You may have a loose or corroded connection at the TPMS computer - on my '07 I "think" it's located under the front right kick panel. Take yours loose and look at the pins for problems, clean them if necessary, and plug it back in to see if the issue goes away.

Your light going on may be the result of a "loss in signal" from one or more sensors, or an interrupted circuit .....

Good luck.
