Ok, is the security light staying on, flashing, or going off?

does it have the regular key ignition or the push start ignition feature?

Customer: replied 8 months ago.
Regular key ignition, we aren't sure what that looks like.....does it look like a padlock? If that's it, it comes on but goes off. Engine light sometimes stays on, but not always. The battery light is constantly on.
Customer: replied 8 months ago.
The screen says "service engine soon", that just came on.
Expert:  Eric replied 8 months ago.


Yes, the security light is the padlock light. If it is coming on and going off within 10 seconds, then the security system is not the issue.

I dont see where changing the filter would cause this issue and am stumped on this one. I will open this back up to other experts to see if one may have come across this before

Ok, thanks

Hello and welcome to JustAnswer!

There are many things that can cause the engine to die but the description does sound much like a security issue. If the service engine soon warning is on though that's the first thing that needs to be addressed. The first step in diagnosing the issue will be to use a scan tool or code reader to see what fault codes are setting and then testing can be done from there Have you read the codes?
