I 100% agree with everything that you said from your perspective. Helio isn't a bad guy, but I do feel like he suffers from the same paradigm as a lot of folks that want to partake in the whole offroad/desert truck lifestyle. They just don't "get" that the hobby is incredibly expensive.
They buy a truck, they go on "runs" with the built trucks. They try to keep up in a mostly stock vehicle ( albeit slightly modified) and LOTS of things break.
Then they realize that what broke is expensive, and costs more to repair than they can afford.
Now we get to the point that bothers me, just like it bothers you.
They then have a truck that is broken or compromised. They need this truck as their daily driver. The only way that they can come up with to get the truck fixed is to pull the " go back to stock and see if we can sneak one past the dealer so they fix it". Not cool. not cool at all. I don't think that Helio really understands how this choice can impact other people because all he sees is a dealer (with money) and Ford ( with a lot more money) and while he can't "afford it", in his mind "they" can. ( which is a crap perspective, but it is what it is)
I'm sure that if I had tried really hard, certain things that I've broken might have been fixed by a dealer. BUT, I was raised to accept the consequences of my choices, so I can't bring myself to do that. It just isn't who I am. I'd rather let my truck sit in the garage until I can afford to fix it.
The problem with Helio's logic is that he feels like Ford should "fix" the steering behavior because it "still does it when I put it back to stock".
The fault in that logic ( and being honest, I glossed past it at first too.) is that the damage was already done by modifying the vehicle outside of factory spec. Whether the behavior still presents is now immaterial.
He doesn't have a data point that clearly shows that the truck was doing it before he modified a single thing. The dealer having replaced all of the parts and reset the computers doesn't count. The dealer could have "missed" the "thing" that is causing the problem that was damaged due to the aftermarket parts.
Damage done. The responsibility to prove that what he changed on the truck didn't contribute to the malfunctioning of his truck is on the end-user. Even if he finds a bone stock raptor that does the same thing, it doesn't prove anything.
From a choices/consequences perspective he now really needs to accept the outcome. I'm sure he's frustrated by the consequences of his choices being that no one can figure it out and he can't afford to fix it. People do ****** things when their back is against the wall.
I get that it makes people pissed. however poor choices with regards to a truck don't make someone a bad person. glass houses and all of that.
I'm pretty sure that the worst thing that he could do is hire a lawyer to "fight Ford" for him. He'd be better served taking that retainer and hourly rate and put it towards taking the truck to a shop that has the ability to properly diagnose and repair the truck.
Or take some instructor-led training courses to learn how to operate the vehicle in a way that doesn't cause the behavior.
Maybe I'm weird, but I don't steer while I'm braking, unless it is a "stab the brakes, set the line, on the gas" left-foot-braking move.
