2005 elantra, the clock light and radio will stay on when engine is turned off. After I shut off the engine, I push the off button on the radio and it will turn off. The clock light is still on.

Mine shut down after 5 minutes if non of the accessories are in use.

Check engine light would have nothing to do with this ! Check engine light is for engine codes ! there is a problem with the radio it self ! or SJB - smart junction box , ford's BCM - body control module . You should take it to a qualified repair shop . or ford dealer !

You shorted something out. Check all fuses and relays. I think you blew a relay not a fuse.

Do you know what kind of radio it is?

un hook batt. or radio fuse then hook back up should fixit

turn off radio-push set up button on right side of display-hour will flash-turn the tune knob on right side to change hour-push knob to set hour and minutes will flash-turn knob to set minutes. when time is set push tune knob

maybe you should check your battery condition. the voltage should be 12.3-12.8V. many times the voltage is not enough to cranck the engine and supply all the other devices. Try to turn on the radio and then crank the engine. if the radio stay on and the clock reset then the problem is inside the clocks mechanism. hope helped.

Turn the radio off then hit the clock button. You can then use the volumn button to adjust the time. It took me a while to figure it out too, LOL.

You have a wiring harness problem
Take it to the dealer directly.......
