2004 Infiniti M45 Reviews

Excellent luxury performance ride. Really happy with interior/exterior appearance and styling. Dash gauges perform as idiot lights which is diappointing. Engine from the factory has had a weak lifter which begins to make noise and gets worse as the oil gets down to the bottom dot on the oil dip stick. This is how I know I am getting low on oil. At no time has an the oil light on the dash ever come on to indicate low pressure even when the oil is below the dip sticks range for adequate engine oil level and the lifter is making lots of noise. I change synthetic oil & filter every 3500 to 5000 miles. The motor has always used 1+ quarts between oil changes. This summer with freeway travel at 80mph in 100-105 degrees I have used 3 quarts of oil in 3,600 miles. So far this does not present an issue for the service writers.

Also the tire pressure monitoring system did not work properly from the factory and another dealer finally replaced the module and now it works fine.

The right front passenger seat is not the same level of comfornt and it has minimum electric seat features compared to the driver's seat.

I expected more from inifinti but I remain happy with my M45.
