Four problems related to gas recirculation valve (egr valve) have been reported for the 2000 Nissan Maxima. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2000 Nissan Maxima based on all problems reported for the 2000 Maxima.
During routine inspection at Nissan dealership technician discovered that the stuctural support for the radiator was rotted. The structural support also supports the engine. Dealership informed me that this is very dangerous and requires immediate attention. The structural integrity of the engine mount is compromised. This seems to be a common defect, as I observed at least 5 other similar complaints posted on the NHTSA website. Owners of these vehicles should be notified of this dangerous condition.
My 2000 Maxima has a check engine light illuminated. Normally, the cars runs fine but approximately 10 times over the last several years in extremely humid conditions and when the temperature is around 50 degrees (f), the idle gets extremely rough. I had the fault codes read and they were p1320 (three times) and p0420 (once). After being read, the codes were reset, but immediately returned. This defect has existed on and off for over two years and has been reset several during this time. When reset the last time, the weather was exactly as described above. The car has 36k miles and is driven around 4k miles per year. My investigation indicated defective coils, which are known problems to Nissan and should have been recalled a long time ago. The car was purchased due to consumer reports great ratings but because of this defect I can safely say that I would never purchase a Nissan automobile again. Asking consumers to pay over $1000 to repair a vehicle built with defective parts is almost criminal. Nissan should own up to its responsibility and recall the known defective parts thus restoring customer satisfaction and vehicle reliability.
Engine runs rough during cold weather (<50 degrees) and trips the code for engine misfire. The code does not always tell which cylinder has the misfire. Engine coils determined to be the problem, but replacement only delays another misfiring for a while. I like the car but doubt I'll ever buy another Nissan because of this issue.
( check engine light come on) rear exhaust and heated oxygen sensor had to be replaced three time.
