This is the 3rd time for: After a hot restart the service tire monitor, air bag light, security light, traction control light all come on. In addition, the fuel gauge show no bars, the fuel average/range numbers missing. It runs and drives OK and a quick turn off and on doesn't change it. After sitting for an half hour or so, upon restart everything is back to normal. Anyone seen anything like that? Maybe a poor ground somewhere? It throws a lot of communication codes for all type of systems but clears on its own or I can erase codes. Not sure where dash ground might be...any suggestions would be appreciated!

Disconnect both cables from the battery and touch them together for a few seconds. this will reset all the modules in the car, it may help.

be sure you disconnect the negative first, and reconnect it second. That may work, but I wouldn't rule out a bad ground somewhere.
