  1. A peeling paint lawsuit has fallen apart after a judge’s recent dismissal.

    The judge said this dismissal is with prejudice because the plaintiffs keep repeating the same allegations that were already dismissed.

    In other words, the plaintiffs had their chance and blew it. The original lawsuit alleged that Hyundai’s paint falls apart as the polymers break down and make the paint susceptible to peeling and flaking.

    ling paint lawsuit has been dismissed by a California district judge. Whether Hyundai knew the paint was defective was a question because the automaker said third-party websites talked about the problems, but customers weren't complaining directly to Hyundai. In other words, if customers don't complain directly to Hyundai, no one can prove the automaker had prior knowledge of alleged problems.

    This is a terrible argument. Third party websites, like CarComplaints.com, are not only useful for venting. Complaint data is collected, compiled, and shared to other owners who might be having the same problem. Seeing how many others are facing a similar issue can be a catalyst for action.…

  3. A class-action lawsuit accuses Hyundai of failing to meet industry standards with their paint in the 2006-2016 Santa Fe, Sonata, and Elantra.

    The plaintiffs say the self-healing process won't work if the scratch is deeper than a surface scratch, such as a chip in the paint caused by a rock flying off the road and hitting the car. Further, there is a concern that if the self-healing process does not occur, the scratch or chip may cause further breakdown of the paint’s molecular structure, in essence triggering the technology to operate in reverse.

    Hyundai’s “self-healing” paint is advertised to heal minor scratches. A chemical compound called scratch recovery clear contains a polymer which, when exposed to ultraviolet light, becomes molten and fills gaps in paint.

    That sounds great, but the plaintiffs claim that long-term exposure to ultraviolet light eventually breaks the polymers down, turning the paint into an ever-molten state that allows it to peel off in sheets.
