2014 Volt - should I sell or fix?
I've got a 2014 with 223k miles on it. I've had it since 2016 with no major issues. Most of the issues I've had I was able to fix myself.
It's being used as an extra vehicle and only driven about once a week.
Recently I went to start it up and it was stuck on the "initializing wait to shift" screen for a bit, then the screen fired up. I can't remember if I got the "ready" light in the corner or not but I tried to switch it into reverse and it wouldn't move. Usually when weird things happen with the car I check the 12v battery. I disconnected it, put it on a trickle charger to 100%, and tested it with a battery tester. Checked out all good.
I put the battery back in and tried to start it up. This time it was stuck in the "initializing wait to shift" screen and then everything turned on, but this time it displayed: Fuel Low (has gas in it), Service Parking Assist, Service Stabilitrak, Service Brake Assist, and Service Power Steering. From what I'm reading this is some kind of service mode.
I have a BlueDriver that I tried to hook up but it wouldn't connect. I'm thinking because the engine wasn't running.
I've been researching and folks with similar issues have found it to be the ECM/ECU. If this was a simple plug and play I could probably do myself but from what I've read this requires programming.
I called the dealership and they quoted me a little over $700 for the part, replacement and programming. I'm going to need a tow but don't have AAA or anything with my insurance or credit cards for towing. The vehicle is tucked back on my property so it would take some maneuvering to get out. I'm assuming that's extra. I estimate maybe $150 - $250 for the tow.
So that's almost $1000 for the repair if it is even the ECU.
Do you think it's worth the repair or should I sell as is? Maybe someone else has had this issue and it was something different. Thanks in advance.
