Two problems related to brake electric antilock have been reported for the 2005 Infiniti G35. The most recently reported issues are listed below.
Brand new 2005 Infiniti G35x, 5 days old. Driving with my son and a passenger up a hill approx 60 mph, entered turn saw a truck, went to apply breaks but they did not work. I turned the vehicle so as to not hit the truck direct and cause less damage. The driver of the other vehicle did not hear the breaks, my son nor his friend felt the vehicle try to stop. Result is $2500 in body damage to my car. The dealer states nothing is wrong and that it is my fault. Infiniti has opened a case but will not have an inspector available until October 24th. 6 weeks from incident.
An intermittent problem has been exhibited twice in the 200+ miles that the car has been driven since we took delivery. The following is a description of what happens. This happened both times while traveling at nominal speeds, about 30 mph and starting to apply the brakes to stop the vehicle. Upon applying the brakes, they felt very spongy and did not stop the car. Simultaneously the engine rpm increased which further prevented stopping of the car. (for a time it seemed as though the engine was working against the brakes. ) when the brakes were depressed harder this continued. Finally, after 5 seconds or so of this very scary and unusual feeling the engine rpm dropped and the brakes started working normally and the vehicle was able to be stopped. Fortunately, both times the stopping was not in a critical situation, and no accident resulted. As a result of this intermittent dangerous problem, we can no longer drive the car and feel safe. Therefore, we brought it to the dealer, competition Infiniti, smithtown, NY, and they are investigating the problem.
