Tesla: Wheel Detaches; Waivers and Nondisclosure Agreements

I‘m teaching Products Liability this summer.  It’s a fun course to teach, and I have a sense of relief about many of the products defects we no longer have to deal with on a regular basis.  For example, last night in class we covered a case in which a wheel flew off a car and injured a child.  That seemed to me an antiquated problem.  Yet today one of my students sent me this article about a 2013 Tesla Model S electric car having the same issue.  Moreover, the company sometimes proffers consumers waivers and nondisclosure agreements as part of the repair process.  Nondisclosure agreements are common in lawsuit settlements, but this seems unusual.
