The contact owns a 2004 Nissan Altima. While attempting to start the vehicle, it failed to operate. The vehicle was towed to an independent mechanic where it was diagnosed that the engine control module burned too much fuel to the catalytic converter and need to be replaced. The catalytic converter was replaced; however, the failure recurred two months later. The vehicle was taken back to the same mechanic where the diagnostic was the same. The vehicle was repaired; however, the failure recurred after two months. The vehicle was taken to fort worth Nissan (3451 w loop 820 s, fort worth, TX 76116) where it was diagnosed that the ignition and exhaust failed. The manufacturer was not notified. The approximate failure mileage was 214,000.
This vehicle exhibits a common set of problems with the Nissan qr25de engine (actually the self-destruction of the pre-catalytic converter which in turn destroys the cylinders, causing overheating, head and manifold damage). The engine overheats and burns copious amounts of oil; sometimes fails to start; runs rough after starting; a/c cuts out due to high engine temp. After half a dozen service visits and replacement of many items, now the dealer recommends entire engine & catalytic converter replacement. We notice that this particular engine as installed in the Altima and on several other Nissan vehicles, is having this precatalytic converter disintegration-and-ingestion problem. Although no lives are being lost (of which we are aware) due to this well-known and well-documented Nissan manufacturing (or supplier) defect, much financial loss is being experienced by countless americans, most of whom very likely believe that their expensive Altima problems are unique to their own car and not a widespread design or manufacturing defect.
