2004 Nissan Titan Engine cooling Problems

“I purchased my 2004 Nissan Titan in april 2010, I took the vehicle in for service on may 6, 2010 and was told my exhaust manifolds are leaking. The warranty is 8 yr/ 80k, I have 82k on my Titan. The exhaust fumes leak into the cab causing nausea and dizziness. This is a safety issue. The dealer won't replace them, because they are out of warranty. The replacement cost is $2000.00.”

“Exhaust manifold cracked and leaking. Nissan dealership diagnosed problem, but Nissan refused to fix problem. I started before 80k miles, but I didn't know emission's had 80k warranty, Nissan refused to fix at 84k. Loud exhaust noise at start-up and while driving, fumes(carbon monoxide) leaking into cabin when idling in traffic.”

“Failure of cracked manifold exhaust with built in catalytic converter. I have cracked 3 manifold exhaust due to the fact that Nissan did not install flex pipes in their exhaust system. It is happening on all the Titan trucks...look at the forums and my dealer has confirmed it. Exhaust is leaking into the cab area. It cost over $900 to just repair the part. They will not fix it! It is leaking straight exhaust fumes.”

“Only 65,000 miles on my truck and no modifications. Right rear seal leaking, pinion seal is shot and front left axle needs to be replaced. Nothing covered under warranty. I am looking at a $3,000 repair bill on a 4 year old truck that has never been off road and doesn't have high miles. My exhaust manifold also cracked at about 60000 miles. This was able to be replaced under warranty.”

“I was driving between 65 & 70 MPH and the engine went into fail safe mode and basically ran at idle speed (10 miles per hour). I parked the truck, turned off engine, restarted, it remained in idle speed only, turned off engine and left off for about 15 minutes - it started and ran normal. Dealer replaced ECM. This occurred in may 2007 and then my son was driving today april 2, 2008 at about 45 MPH and engine just cut off completely (now at the dealer). …”
