2006 Maxima Service Engine Soon light

[tparkerhr]

I have a 2006 Maxima with 34,000 miles that's oxygen sensors have been replaced 4 times and is still at the dealership now. I don't know much about cars but the dealership says they have replaced the electrical system, wiring harness and there's still problems. They told me Nissan has looked at sending an engineer with another harness. I've seen a lot of comments about oxygen sensors being replaced so I was curious if anyone has had these types of problems. I'm almost at my warranty which scares me. This is my 4th Nissan and I've always been very happy with them and have never had problems like this.

Welcome! Sorry to hear about the problem, though.

I'm almost at my warranty which scares me.

I wouldn't let that worry you too much. Since the dealer knows the issue has existed since before the warranty expired, they should still cover it under warranty even after the warranty period expires.

Another harness sounds like a logical step to me.
