Two problems related to brake disc pads have been reported for the 2005 Infiniti G35. The most recently reported issues are listed below.
Rear brake wear out at 17,000 miles.
Leased vehicle, highway driving and very limited local/city driving. Brakes had 'grinding' noise whenever initially applied and I was told by dealer that was how the "european brake system" sounds -? required front brake pads/rotors replaced at ~ 19,000 miles 8 months after acquiring the car. Rear brake pads/rotors then had to be replaced 13 months after acquiring the car at ~ 29,000 miles. Was told when had car in for faulty air bag light ~ 6 weeks ago front pads were worn to 4. 5 mm. Car is in for 38k service now and it is suspected I am going to have to replace the front brake pads, again after only 19,000 miles since new pads were put on!.
