What 2003 Infiniti M owners say
Most recent owner complaints, unedited.
Purchased car from marin infiniti in august, 2011. Next day car stalled driving in a 50 MPH zone and had to be coasted to side of the road across traffic. Fuel gauge was found to be inaccurate, gas tank was empty when gauge stated 7/8 full. Marin infiniti was unable to assist. Fuel sending unit was replaced for $400. Gas gauge continued to be inaccurate, giving false readings and even increasing and decreasing readings as the car was driven. My mechanic called a local infiniti dealer who stated this was a known problem and could only be cured with replacing the dash instrument cluster for $600.car is currently in the shop for this repair. Contact with other infiniti m45 owners proves this is a known defect by the manufacturer which, depending on what personnel is are contacted at nissan/infiniti, has sometimes been covered under warranty and sometimes the manufacturer's reps deny the issue, forcing the public to pay for manufacturer's defects.
