After having the heads replaced by a mechanic, none of the bells or lights come on when the ignition is on except for check engine. And then after starting the dash says security problem car may not restart, traction disabled, stability reduced, all trans selection lights flash, heater comes on everytime I start car as if the battery has been disconnected but it hasn't. And the headlights work but brights won't come on even though the indicator lights up. Sometimes when I turn the headlights on it takes about 5-10 seconds for them to come on. Also guages don't work for about 10 seconds after starting.
