A few weeks ago, my car was only turning over on the third try. Eventually it wouldn’t turn over at all without a jump. However, dashboard and lights would come on even without starting. My mechanic just replaced the main battery and auxiliary battery. I still have the same issue. Turned over on second or third attempt. Now not at all. Batteries are in the car less than a week. My mechanic is old school and said there’s so much computerized with the car I need to go to dealer.

This is typical when the electronic ignition switch control unit goes out, but we should do a CAN scan to see if any codes are stored. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

Here is how to change the part out if a code comes up for it so you can see what needs to be done to fix the problem. Check out the images (below). Please upload pictures or videos in your response to the problem so we can see what's going on.
