I would go to a different dealership. Take a copy of the latest tsb and get them to scope it. The tsb is quite clear and does not include listening with a stethoscope. The thing about canvap is that I think you have to agree their decision is final and binding. If it was me and no dealer would help. I would get an independent scope video then get a lawyer. Good luck, be persistent, but try and stay calm. I am in BC also and I was told there was nothing wrong the first go round.Wow man! I too am having problems with dealer out here in BC (Lower Mainland) I have already talked to someone at CANVAP so I will be filing a claim probably Wednesday. As I have a 2017 and have only till September 30 to file. This should not be happening! I bought a Truck in good faith from Nissan and now I am getting a runaround. First the Tech at the dealership who could not do a 30 minute job the first time forcing me to contact Nissan Canada and complain. And the second time around the tech hands me a 38 second video of the borescope cyl 7 and 16 seconds are nothing but a blur. And the scarring seen on the vid for all of less than 2 seconds, looks just like the scarring on Nissans engine knock bulletin. The tech then tells me that it's a vertical view when I know I am looking at something horizontally. Then the tech tells me he re stethoscope the engine and it all sounds the same. Which I responded "well does engine noise not travel through the whole engine echo" which the tech responded yea. Well then why bother stethoscope when one can take a 60 second clear vid of cyl 7 to be sure it's ok.?
Well I have emailed the Nissan rep twice since the borescope and phoned once leaving a message no response so time to file a claim with CANVAP as this is telling me the engine is bad. I did see a 2018 Titan for sale in Kamloops with about 60000 KM on the odd with a LIFETIME engine warranty. Wow expensive engines eh Nissan! AND WHAT A FRIKING HEADACHE FOR THE OWNERS!!!!
