Pressurized vehicle components always have a chance of injury when they go wrong. On Mercedes-Benz's super-old 600 sedan, if its complicated hydraulic system sprung a leak, it had enough pressure to slice through human tissue. So you want to play it safe where pressure in concerned. Case in point, this Nissan recall.
Nissan is recalling 108,503 examples of the 2014-2016 , all of which have build dates between 31 July 2013 and 16 January 2016. The issue lies with an anti-corrosive treatment on part of the rear liftgate.
Nissan claims the treatment was "altered from specification," so corrosion might actually eat away at the piece despite said treatment. If that happens, a sudden release of pressure could cause the liftgate's stay to break off, which might cause an injury. Rapid depressurization is not often a good thing.
Correct replacement pieces are not yet in place, so Nissan is sending out a preliminary notification to owners. A second notification will be issued when replacement parts are available. Both rear stays will be replaced when parts reach dealerships.
