Yes. Over-engineered crap is still crap. I watch a mechanic "South Main Auto Repair" on YouTube. He's a wizard when it comes to tracking wiring and code problems. Fuses working but circuit isn't or is throwing codes. He's in up-state NY, and in the rust belt. Had one truck in that was simply stumping other shops. Turned out to be the chassis ground strap had rotted. It was braided copper and crumbled in his hand as he went to check it. The truck was maybe three years old. Some things would work then not, then all kinds of unrelated codes were thrown. What a fricking nightmare.
It’s not wizardry:
It’s well-known among gear heads that mysterious vehicle problems are most often caused by poor electrical connections, notably ground connections.
It’s auto repair 101: Have an electrical anomaly with one or multiple symptoms, ‘go to ground’, so-to-speak. ESPECIALLY in states using road salt.
That stated, my boy went through UTI; they don’t teach that little nugget.
For others reading this, wisdom to interpret a Carfax report lies therein.
