Tire pressure monitor - stayed on after vehicle was serviced at dealer for 75,000 mi check up which included extensive review of all vehicle systems. After checking cold pressure several times and driving vehicle for several days tire pressure monitor would not go off. Returned to dealer and requested the problem be fixed. They were helpful and polite but tried to charge me $160.75 for replacing the monitor because the battery went out in the monitor. I am complaining that I should not have spend $160 for each tire monitor because it's battery expired. The batteries should be replaceable in the tire monitor. I think it's unfair and poor design to require Nissan owners to spend $640 over time to keep an important safety feature operational. This system needs to be redesigned to reflect a much less expensive(replaceable battery) replacement part or replace the monitors free of charge.

My 2009 Nissan Frontier came with a full size spare tire that had no sensor for the tire pressure monitoring system. This means that, when I rotated the tires, the tpm system lit up and stayed on. Further, the system will stay on 80% of the time, which is the amount of time that the spare will be on the ground during the life of the tires. It will be in the spare position only 20% of the time. It seems that adding a sensor to the spare should greatly increase safety with only a slight increase in cost per vehicle.
