Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. 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 4WD 4-cyl

  • Automatic transmission
  • 1,000 miles
I purchased a 2006 Altima Nissan 2.5 special edition in Feb 2006. Within a 6 months time frame I have had 2 engine replacements. This still hasn't corrected the oil consumption problem nor the clicking sound. I have also been informed that the clicking and grinding sound may be attributed to bad tires. So I took it to another company that deals in tires and was informed my tires were in great condition. Then on Jan 22 I was told I needed a new steering wheel to help with the sound and vibrations. My Nissan sounds and rides like a truck. Nissan needs to just live up to the fact that some of the 2006 models were just not built correctly and compensate the consumers that are feeling the affects of buying a lemon.. why would they put their reputation in jeopardy. Do they not realize this could turn into a class action law suit. Several of my friends have had their cars bought back under the lemon law but I'm getting the run around from one of the Nissan reps. It doesn't take a rocket scientist to know that after replacing 2 engines in a 6 month period to know my car is a lemon.. Nissan has lost my respect due to the non caring nature they have represented.
