Drove the cirrus to work today . Went over some speed bumps and all the lights turned on in the dash then went away . Would would cause that .
A loose negative battery cable on the inner fender...
Remove the UPPER nut from the negative post on the fender, then remove the upper cable.
THEN, examine the lower cable and nut for corrosion, clean if needed, and then tighten the lower nut.
You can then reinstall the upper cable and nut.
After checking the negative cable, inspect the positive cable at the PDM/fuse box.
If the issue still occurs, remove the left front wheel and inner finder and check the connections at the battery itself.
