During routine recall for ECM module the dealer informed me that both exhaust manifolds are cracked as this has been a recurring issue with this model vehicle causing exhaust fumes to enter the cabin and also cause poor performance with the vehicle. Dealer quoted this as a $3200.00 repair and will not assume any portion of the repair. Dealer "beaverton nissan" has informed me that this issue is due to the poor quality of the exhaust manifolds any possible faulty welds on the product combined with material that is too thin to start with. The presence of exhaust fumes in the cabin while idling and/or driving is a severe safety hazard. I have opened a case with nissan north america and have been advised by three independent mechanics to park the vehicle until it is safe to drive.
