I've been experiencing some frustrating reliability issues with my Nissan over the past few months and I'm curious to know if others have encountered similar problems. Specifically, I've noticed a recurring fault code related to the engine's timing chain system, which has resulted in repeated trips to the dealership for repairs. Has anyone else experienced issues with their Nissan's timing chain or other critical systems? What were your experiences with diagnosis and repair? I'd love to hear about any similar problems others may be facing.
