The Frontier is a 2013.
I did call Nissan customer support line, politely asked to escalate the call. Nissan called back, refused to entertain the possibility that this problem existed from date of manufacture and their technicians either overlooked the root problem or deliberately pushed the problem out of warranty. The non-technical Customer Service Rep at Nissan stood firm on their excuse that it was now out of warranty. They denied my request to escalate this to the National Service Department Manager. They also did not send me any documentation of the complaint, only a verbal case number.
