Notes: The 2006 Nissan Altima has a trend of engine problems, both in our data & definitely in the NHTSA's complaint data as well.

Excessive oil consumption is the main problem reported by owners. Nissan did a recall back in 2006 for oil consumption due to bad piston rings, but many owners report to us that the recall didn't fix the problem.

The dealer only had to check the oil consumption rate. Typically 1 qt per 1,000 miles is "acceptable" per OEM standards ... that's a lot of oil!

Altima 6-cyl

  • 81,300 miles


Beginning 2009 at roughly 40,000 mi the car began to rattle while accelerating, I took the car to the dealership and they determined that the catalytic converter had failed and it's mount to the engine had broken, it was replaced. Then at 81,300 mi I was driving 30mph when my engine light came one, I made an appointment and took the car to the dealership the next morning. I was told again the catalytic converter had gone and in turn taken out the ego sensor as well.

The contact owns a 2006 Nissan Altima. The contact stated that while driving 45 mph, the catalytic converter and the crankshaft sensor failed as the vehicle stalled suddenly. It was restarted within five minutes. The vehicle was taken to an authorized dealer who repaired the crankshaft sensor but not the catalytic converter. The contact called the manufacturer who offered no assistance. The failure mileage was 90,000 and the current mileage was 120,000.

Altima 4-cyl

  • 53,025 miles
I have a 2006 Altima and there was a recall on oil consumption, the dealer said I needed a catalytic converter, then he said it wasn't under warranty, when I called Nissan hq they said I have up to 80,000 miles which I only have 53,000 on my car. The end result the catalytic converter caused my engine to seize and now I have no car and still have 10,000 dollars of car payments. The dealer is hillside Nissan in New Jersey.
