While driving straight on interstate I-95 during rush hour at approximately 30 miles/hour, I pressed on the brakes and the pedal dropped down and started making a weird noise (like grinding sound) and the car wouldn't stop. The ABS light turned on, check engine light turned on, the pedal lost pressure and the brakes locked up. I ended up in a crash, rear-ending the vehicle in front of me. The car has now been repaired from damages from crash but mechanic found no problem with brake system.
I have a 2005 infiniti qx56. On april 5, 2007 I got on the ramp to the highway and at the entrance of highway suddenly the car's driver size front suspension broke. This sudden mechanical defect caused the car spun out of control at 6:30 pm in afternoon traffic than it was rear-ended by the car behind which caused 4 car collision.
Inadequate brakes on 2005 qx56. Manufacturer is aware of this problem in 2004 but has not issued a recall to date or sent letters to customers about the issue. Brakes overheat and prematurely wear out at 2000 to 2500 miles causing a violent shaking of the steering wheel and control issues. Infiniti is replacing brakes however 2 to 3 months predicited wait for a real fix. Service advisors are reluctant but have admitted the brake design is inadequate for this vehicle.

Left headlamp has condensation collecting and high beam was not functioning. Bought a replacement bulb and found this not to be the problem. "box" located in the headlamp that is square and hard plastic has water inside this. Part was looked up and found to be >$300 to replace. Is there a recall on this particular issue. The right headlamp is working fine and has no condensation.
