staying with the theme of the article, by doing this repair as goodwill, it changes how they have to report it (if at all). So if there really would need to be a recall to fix a fault/safety issue with the exterior door handle, the data wouldn't be there for regulators to make it mandatory. Warranty doesn't apply in these cases. If a recall defect is discovered 5 years after warranties expire, the manufacturer is still required to fix it on all cars impacted. One of my vehicles had a seat belt recall 10 years after. So your "goodwill" could be just them trying to avoid a costly recall.

Note: this was just staying with the theme of the article and not that I agree with the accusations.
