My wife was driving our 2 year old son on Saturday when the brakes failed. She was approaching an intersection and attempted to apply the brakes, but the brake pedal would not move. She tried over and over and the brake pedal finally moved. The brakes applied and she was able to stop the car before anyone was injured. Naturally, we are unimpressed with this vehicle now. We had it towed to the Infiniti dealer where they are attempting to locate the problem. Has anyone experienced this issue?
