Hello,
I am experiencing a sudden power down after auto off engages. The car will power right back up after I release the brake pedal, however, I cannot put the car in gear. I have to turn the ignition off then back on. I get an error message flash ( something about take to dealership, do not shift). It flashes so quickly I cannot get a picture of it. I took the car to dealership and there was no code. I had spark plugs replaced and it lessened the occurrence but it does still happen from time to time. Has anyone experienced this? What was the cause/diagnosis/outcome? What should I tell the dealership to look for?

TYIA for your input!!!

Have you tried turning off the Stop/Start and drive it that way and see results. Some have reported that the batteries needed replacing.

Its your battery. Don’t bother testing it. It might test good. Replace it. Start by replacing the aux battery for this one.
