> So long as the hack didn't cause the problem they are legally obligated to honor the warranty.

I agree. The problem is that you could update the software to void the warranty, then do a factory reset when you have problems. Deere would never know that you operated the tractor outside of the parameters that they designed, built, and tested, but then they would be on the hook for it.

> Upping the fuel pressure and changing some maps should not cost the consumer $10k. The markup in that is ridiculous.

My numbers probably aren't that accurate, but they're not selling just software in that case. They've already bought an engine (for cheap) that is capable of that horsepower. They just don't realize the cost for it until they actually upgrade.
