Both of the exhaust manifolds and catalytic converters in our 2011 nissan armada have cracked. as a result, exhaust fumes were leaking into the passenger compartment creating a potentially deadly concentration of c02 fumes in the passenger compartment. this is a known design/engineering defect on all v8 nissan armada and nissan titan engines for at least 10 years. nissan will only cover the federally mandated 8 year/80,000 emissions warranty. c02 inhalation causes hundreds of deaths per year in the us. this is an obvious safety issue that is known to the manufacturer and well documented in thousands of cases. as such it should be covered in full by the manufacturer. this repair cost us $2439.36. nissan should reimburse us in full for the repairs.
During a family camping trip, towing a camper, at ~54,000 miles the exhaust broke off the vehicle at the mounting flange just behind the muffler. this caused exhaust to heat the floorboards just at the 3rd row seats, melting the plastic cover to the mounting bolts of the seat to the floor, and melting the carpet in the same area, and filling the cab with melting plastic fumes. it also melted the rear air-ride suspension air line, causing the system to be in-operable while towing and off balance loading while driving.

Tl* the contact owns a 2011 nissan armada. after starting the vehicle, a ticking noise was heard coming from the engine compartment. also, the vehicle would not accelerate properly and stalled on multiple occasions. the vehicle was taken to nissan of lake norman (18615 statesville rd, cornelius, nc) to be diagnosed, but the cause of the failure could not be determined. the vehicle was then taken to an independent mechanic who diagnosed that the exhaust manifold was cracked. the manifold was replaced, but the failure recurred. the manufacturer was not notified of the failure. the failure mileage was 140,000. the vin was invalid.
The oil fill spout came off the valve head cover resulting in massive oil spill. i was lucky i discovered it after a short trip to the store. both pieces are made of plastic and poorly glued together with something that resembles silicone. it had completely deteriorated (the car has 49,000 miles on it) . very disappointed that nissan wouldn't spend another 15 cents and hold these pieces together with a clamp of some sort. i had just come back from a 650 mile trip, if this would have happened on the highway the engine would have ceased up or the car might have gone up in flames.
The car totally shut down multiple times without warning while i was driving. the first time that i took it to the dealer it saw thought the problem was a faulty sensor in the transmission. the sensor was replaced. 4 days later the same thing happened again. the second time that this happened the dealer replaced the whole computer. i no longer have the suv. *tr
