Two problems related to engine exhaust system have been reported for the 2001 Nissan Pathfinder. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2001 Nissan Pathfinder based on all problems reported for the 2001 Pathfinder.
Engine service light - catalytic converter. My mechanic fixed the engine sevice light being always on by bypassing something on the catalytic converter.
The entire exhaust system (from and including y-pipe and back) had to be replaced because the entire system was completely rusted out. My mechanic said it was the most rusted out system he had ever seen. I believe this was due to incorrect making of the product. This may be similar to the other recall in which the lack of properly coating the items caused premature rusting.
