Please someone help! 2014 Silverado 4WD 50k miles. Head lights dim when I put the windows up and down, ONLY when driving slowly through a parking lot, making a left turn causes power steering to fail, AC to shut off and then the engine dies. Starts right back up. Occurs once every couple days. Does not throw up any codes nor does check engine light come on. Just says “steering assist disabled.”

Attempted fixe at the Chevy dealer:

First time they said #8 fuel injector was failing (not covered under warranty cost $700 to fix) Two days later problem is back.

2nd trip to Chevy, they said fuse panel was bad and causing the issue(again not under warranty $360 paid) 5 days later problem is back.

3rd trip to Chevy, they kept it for 3 weeks. Said now #6 fuel injector failed. (Again not under warranty, $700 to fix) so here I am three days later after picking it up and problem is back AGAIN! Any help is greatly appreciated! I’ll buy you dinner or booze if you can help me solve this problem!
