So I was driving home last night, and the starter system problem came on as I was driving. I arrived home and the PGM-Fi came on , while the engine was off. There was no change in performance and my veh won’t start. Any ideas, something I can fix or dealer only? There is 70,000 miles on the car, is this covered under warranty? Approximate cost to fix? Thanks in advance

Did you do any maintenance or anything that would require disconnecting any part of the electrical system? Whether or not you did, double check electrical connections, make sure they're snug (particularly battery terminals) then drive around for a bit. Wouldn't hurt to disconnect the battery for a few seconds, reconnect and drive around. I had a christmas tree of random warnings with zero performance change, did the above, and it went away. Happened a second time after I disconnected battery stuff to install an HID relay harness and same method made the lights go away.

I’ve disconnected the battery several times, including over night. It won’t even crank. The display says something about initializing and all the light come on. I’ve done no electrical maintenance nor have I touched anything besides disconnecting the battery
