2008 Infiniti G35 114,000 mi,
When braking I have the most annoying vibration felt thru the entire car. and if I'm coming to a gradual slow stop I can hear a deep scrubbing/griding sound coming from the left front rotor. Someone states possibly control arm bushings worn out? Bearing? I swear I think it's the rotors. I had them turned 1 time already and only had the car 3 months.. It just rumbles worse and worse.. I'm going to Replace brakes and rotors with StopTech high performance. PRAYING this stops the vibration/srubbing. My car is too nice to stop so CRAPPY. Infiniti needs to clear up the issue
2008 Infiniti G35 75,000 mi,
I have the same problems when applying on my brakes at high speed (55 to 65) and my brakes give out and I can hear a grinding noise coming from the sudden brake. I nearly had a couple of accidents. On a rainy day, it does not handle sudden brakes at a speed of 15 to 25 miles - came close to having an accident. At the time i only had 75,000 miles now I have 100,005 miles and I still have the problem. I take my car in like I'm suppose to, it has not been diagnose that I have a problem.
Under warranty the dealer turned the front rotors and added brake air line ventilation mechanism.
