Is Tadge Juechter setting up Mary Barra by hiding problems with Corvette C7 Stingray chasis integrity, endangering the buyers?

When unlucky Stingray buyer had his rear suspension fall out of the car , +General Motors  ended up buying the car back from the unlucky owner, making the issue disappear, just like the recall ridden corporation would be expected to do.

As of now, there has been absolutely no explanation what and why happened.  How many more of these problems is +General Motors  hiding?

What makes the entire matter smell really bad is the fact that lately, AFTER this accident was disclosed publically, there is a number of cars held up in Bowling Green under so called quality hold, citing frame integrity as the reason.

Is there a problem with the integrity of the new aluminum chassis and newest welding methods?  Hopefully, GM would not profits over safety of the buyers as it has done prior to the 20 MILLION recalls that are being implemented already.
