Iam having the same model 2009 safrane or the Renault-Samsung SM5 A34R and been using it for more than 6 years without any problems until hell broke loose and engine got burnt. its been 2 months and been trying to fix my car but everyday is a different problem. The original parts from the company are so expensive that cant afford it. getting a second hand engine and second hand parts in UAE market was impossible. Replaced the gasket kit,rings,radiators,engine
cooler etc original and resurfaced the pistons. spent almost 4000$ including labour from a local garage.
Found a new problem today which seemed to be a engine mounting kit issue all this while and turned out to be a camshift sensor issue. Does anybody know which other car model camshift sensor would support my model? Nissan Alitma or Maxima?
