We purchased a new 1995 Nissan Maxima in July 1995. By April 1996, the still-new car had to be repaired with a new O2 sensor, but under the warranty. Then by October 2000, another new O2 sensor had to be installed, and was paid out of our own pocket. However, by February 2002, the dealership diagnosed the car with yet another O2 sensor failure. At that time we refused the service because we had lost confidence on the repair due to past poor quality history and high repair cost estimation (~$250). The dealership now routinely warns us to repair the sensor, but refused to recognize the sensor quality and/or vehicle engine operation that, in my opinion, was the cause of the repeated repairs.

I took delivery of this auto 11/17/94. On 10/11/95, a rear oxygen sensor was replaced at 5510 miles, under warranty. Sometime after that, in 1996, I received an undated bulletin from Nissan, acknowledging a problem with their emission control system and extending a "limited warranty" to 5 years or 60,000 miles. On 7/11/00, a front O2 oxygen sensor was replaced under warranty at 43,121 miles. On 2/6/2001, a third O2 oxygen sensor was replaced at 45,408 miles, with a cost to me of $636.17. This indicates to me that they problem is more serious than replacing O2 oxygen sensors, and if in fact it is the O2 oxygen sensors - they all should have been replaced before their "limited warranty extension" expired. I believe I have a legitimate complaint and that Nissan has an obligation to honor it by reimbursing me and replacing the 4th O2 oxygen sensor in the emission control system, and any other parts related to this problem.

Dismayed at number of problems, ranging from a leaking trunk to problems with the O2 sensors. Now the tachometere and odometer have failed. These are all expensive repairs. The maxmia is supposed to be Nissan's flagship car.
