Brake Disc Caliper problems of the 2004 Infiniti G35

Brake calipers have frozen up have been replaced along with rotors and brake pads on four occasions. These same incidents were repaired on 6/16/2008; 4/25/2009; 9/12/2011 and will be again on Monday 10/22/2012. This is clearly a vehicle defect that is seriously dangerous for any Infiniti driver, the passengers and certainly any other drivers on the road. I strongly suggest that the NHTSA look into the matter. Thank you.

The contact owns a 2004 Infiniti G35 sedan. The contact felt abnormal pulsation when the brake pedal was depressed. He took the vehicle in for routine inspection on five different occasions and had the rear and front brake calipers, rotors, and pads replaced. All of the remedies have been insufficient in correcting the failure. The dealer stated that this was a normal characteristic of this vehicle. The manufacturer did not assist. The failure mileage was 12,802 and current mileage was 32,042. Updated 2/18/09 the steering wheel knuckle was replaced. Updated 05/20/09.

I leased a 2004 Infiniti g-35 coupe and after approximately 36,000 miles, the car started smelling hot and would violently vibrate when driving. The closest Infiniti dealer is approximately 40 miles away so I took the car to goodyear and they installed new brake pads on the front tires. Less than 30 days later, the problems still persisted and I took the car back to goodyear and they installed new rotors and brake pads on the rear wheels. This did not fix the problems and 30 days later, I took the car back to goodyear and both the front and rear brake pads were totally worn down. They said I had a problem with the brake system, possibly the calipers, and suggested I take the car to the Infiniti dealer. I took the car to crest Infiniti in plano, texas and they said the brake fluid had been contaminated. They sent a sample to a testing lab but no test was done because the alleged contaminant was so small it could not be measured. Crest infinity refused to repair the brakes under warranty. I immediately too the car to grubbs Infiniti in euless, texas and they also decided to test the brake fluid. After three weeks the test revealed no contaminate in the brake fluid but grubbs said that since the brakes had been worked on by goodyear, the warranty was voided. I have checked the internet and found hundreds of complaints about brakes on the Infiniti g-35. Class action lawsuit's have been filed in both California and florida. I found many postings with the exact same problems that I am experiencing. Infiniti refuses to admit that a problem exists and refuses to repair vehicles, including mine, under warranty. The problem has nothing to do with brake pads. There is a problem in the braking system that causes the brakes to be applied when driving the car resulting in excessive heat and excessive wear. This is a serious problem and Infiniti is ducking the issue and refusing to issue a recall to repair this serious defect under warranty.
