The contact owns a 2006 Nissan Titan. The contact started the ignition and a loud noise emitted outside of the vehicle continuously. The vehicle was taken to a dealer who was unable to duplicate the problem. The contact inspected the vehicle and stated the exhaust manifold was cracked. The vehicle was not repaired. The manufacturer was notified of the problem. The approximate failure mileage was 60,000.
Noticed upon starting the vehicle, a clicking sound which became louder when driving. Vehicle was under warranty. The dealer stated the exhaust manifold was cracked. They fixed it. Shortly after the other exhaust manifold cracked and they fixed that as well. Since then, the warranty has expired and either one or both exhaust manifolds have cracked again. I was told it was going to cost literally thousands of dollars to repair. Unfortunately, I can not afford to repair the vehicle. I was upset, but was willing to accept the situation, until one morning I got a strong smell of exhaust in the cab of the vehicle. Being a mechanic, I had my hunches. It doesn't happen all the time, but on occasion I get exhaust emission in the vehicle. I have also recently found online that there are an abundant amount of other Nissan Titan owners complaining of the same thing. There is also the possibility that if the leak is around any wiring, the hot gas may cause the wiring to melt causing a possible engine fire. That of course is just an educated opinion. How many more exhaust manifolds have to crack before Nissan will admit they are a defective design. Is it about the money to recall the vehicle or is it about safety after all? in addition, I would have completed this form a lot sooner, but I was just recently informed about it. The vehicle obviously has more wear and tear and more mileage, but the fact remains that this happened many miles ago. Thank you for taking time to read my letter.
The exhaust manifolds crack and cause engine warning light. Only fix is to re place manifolds. Manifolds are manufacture defective. Cost to replace is over $2000. 00 Nissan stated no recall.
