2008 Nissan Titan Engine Problems

“The exhaust manifold on my Nissan Titan cracked prior to reaching 95k miles. With the crack, exhaust fumes are making their way into the AC system causing the cab of my truck to become filled with carbon dioxide. I have done adamant research and determined that I can replace the manifold at a local shop, but that almost every Titan owner out there has experienced cracked exhaust manifolds.”

“I have a leak in my exhaust manifold and at this time no fumes have come into cabin yet but do to so many problems of this type and when you replace them the manifold are cracked again.”

“Puchase from private party in february, Nissan ran diagnostics immediately after purchase. Leak was not recorded. Accident happened in june, vehicle returned in september, approximately a week after pick up, coded leak in emulation system, manifold/exhaust causing fumes to back up into truck while stopped, extreme fuel consumption and lack of power, causing idle to idle low at stop. This developed after a sideswiped hit accident and transmission being replaced. Left and right sensor also coded.”

“Both exhaust manifolds are cracked, Nissan dealer acknowledged this is a known defect and will not replace. After research online, many other owners experience the same problems. Estimated repair costs are over $3,000”
