They could only absolutely do option one.

Option 2: If Honda sells an engine by itself with a warranty then it doesn't matter what car it gets put into. Now if Honda was able to prove that the engine failed because of the vehicle it was put into then they could void the warranty. Just putting it into another vehicle is not enough to void the warranty just like putting aftermarket parts on a Honda engine is not enough to void the warranty.

Option 3: They would have to back that up with proof otherwise it would be slander/libel and Ford could sue them.

Option 4: Once again they would have to prove it to be true. Otherwise it just isn't going to happen.

I put a new long block into my car and it came with a 3 year/50,000 mile warranty. They have no idea what car it went into and no idea how I have it hooked up. What they did do though is put a little heat activated tag on it so they can tell if the block has overheated. And by looking at it they can tell if I did other stupid stuff.

Jack Kevorkian helped terminally ill people who had made a rational decision to end their lives with dignity, was convicted of 2nd degree murder and spent 8 years in jail.

Lori Drew drove a (relatively) healthy young lady to make an irrational decision to end her life, was convicted of a few misdemeanors, and is not imprisoned.

These are entirely different scenarios and has a few errors. First problem is that Kevorkian's intention was to kill. Was Lori Drew's intentions to kill the girl or not? Maybe but you can't be absolutely sure. The most important problem with your statement is that the girl wasn't relatively healthy. She was already on medication with a known side effect of increased suicidal thoughts.

I have made fun of people and people have made fun of me. It has always been in good fun and I've never meant any ill will by it. If I say you are ugly and you go kill yourself, should I be held accountable for killing you? As horrible as it is, Lori Drew should be held accountable for harassment and not murder unless they can prove beyond a reasonable doubt that was what Lori Drew was trying to do.
