The car was on and driving when the “battery save mode” warning came on. At the time of the warning volts, were showing around 11 while running. After the car was off, about 4 hours later the car was attempted to start. Dash lights, radio, etc, all worked fine but the car wouldn’t crank, wouldn’t turn over. Vehicle was jump started from another vehicle and started immediately. The car drove home for about 10 minutes with volts reading 14.6. After shutdown, volts were 12.4 with the car off. The car wouldn’t crank, wouldn’t turn over. Jump start attempt with a “jump start battery pack” failed. Wouldn’t crank wouldn’t start. Volts still reading 12.4 from the battery. Attempting to start the car with the lights on, and lights did not dim while turning the key. The alternator and battery are only 8 months old. Not sure where to begin with repair.

Hi,

First, and don't laugh, see if it will start in neutral.

Next, there are three fuses I need checked in the under-hood fuse box, fuses 1, 2, and 16. If you look at the schematic below, they are at the top of pic 1.

If the fuses are good, confirm there is power to and from them.

Here is a link you may find helpful:

If that checks good, one at a time, remove the starter relay and switch it to a different relay having the same part number. If there is no change, do the same with the starter pinion solenoid actuator relay.

If there are no other relays with the same part number, here is a link that explains how to test one.

If they test good, have a helper turn the key to the start position while you check for voltage at both the yellow wire and the yellow wire with a green tracer.

Let me know the results.

take care,

Joe
