In practice someone facing liability for having done something at the level of killing a pedestrian or illegally poisoning a field will be doing everything they can to reduce their exposure.
Claiming the problems result from the original design and not the changes may be their first step in their defense.
Once that defense has been raised, it won’t necessarily be simple to prove whether the repair was the cause of the problem or not.
But, this is an interesting issue. Perhaps the right to repair would be more palatable if it came with a blanket indemnity from legal liability for manufacturers once the device is repaired or modified in any way.
...which is exactly what a manufacturer would do if they were sued. what you are describing is a problem with the legal system and not with repairing our on property.
> When purchased equipment is altered, the manufacturer is generally released from liability unless the manufacturer could have reasonably foreseen that purchasers would alter the equipment in the manner that resulted in injury.
So if you could have modified a tractor in a way that was not obviously bad and the manufacturer didn't try to stop you from doing it, the manufacturer could still be liable.
Is it reasonable to believe that if the purchaser has the ability to modify the software, they will? If so, how does one rewrite the liability laws for farm equipment?
And while physical modifications may reduce manufacturer liability - what about software? And the ability to reset the software so that evidence of the changes are no longer present?
There's a challenge with the law for repair and liability for farm equipment that needs to be reconciled. That liability issue doesn't exist for other domains (modifying a personal computing device). You aren't likely to find a $6M claim against Apple for ripping someone's arm off - that is an issue with farm equipment.
