Rear axle seal failure caused lubricant to coat emergency brake, resulting in slippage.

Drivers side rear axle seal failed allowing differential oil to leak onto brake pads and rotor. This is a very unsafe thing that could lead to reduced braking in an emergency and needs to be addressed.

Brake hard to avoid collision with deer crossing highway and vehicle did not stop quickly as expected. Due for disc brake pad replacement in the future and this incident prompted a check of brake components. Discovered left and right rear axle seals, pinion seal and rear differential cover leaking differential fluid. Rear brake calipers, brake pads, parking brake assemblies and rotors were covered with differential fluid. Entire rear differential assembly overpressurized due to faulty, poorly designed oem check relief valve, resulting in failure of all seals. Same concern as in service bulletin ntb-10-008. Same problem with Nissan Frontier, xterra, titan and armada models. Nissan admits that fluid from the rear axle leaking onto the brake pads is a concern, but will not address why the axle seals are failing at an alarming and premature rate. A recall is needed for Nissan to take responsibility for their design flaw. All fluids personally changed out at 66,680 miles on 8/25/2011 and there was no evidence of leakage anywhere at that time.

Traveling down the road in stop and go traffic I looked in my rearview mirror and then back to the vehicle in front of me. I was doing 15-20 mph and saw they had stopped and I was in danger of a collision if fast action wasn't taken. When depressing the brake pedal in a panic manner the vehicle did not slow due the accelerator being depressed at the same time as the brake due to the closeness of the pedal. This resulted in a accident involving 3 autos including my 2006 Frontier SE 4X4. This problem has been noted several times before by the cpsc.

The consumer stated the left front caliper would seize. The vehicle was taken to the dealer and they replaced the front pads and turned the front rotors. When the consumer took the vehicle for a tire rotation, it was discovered all four rotors needed to be replaced. The consumer believed the problem was due to contaminated brake fluid.

I was driving down a steep hill and applied the brakes they went to the floor and I had no brakes, I went over an embankment. I continued to pump breaks and they finally came up enough to stop me in the field. The air bags deployed.

Brakes failure due to rear axle leak. Myself and 10000's others have been having a problem with the rear seals failure due to a faulty air vent that clogs and hot air will build up and the seals will fail and the oil get all over the rear brakes causes the brakes to fail.

I have a 2006 Nissan Frontier pickup id # [xxx]. I had to replace the front rotors at 20,000 miles and now at 40,000 miles I am having to replace both front and rear rotors. I am 60 years old and have not changed my driving style. These brakes seem to be wearing out at about three times the rate of the brakes of any previous vehicle that I have known. This seems to be a design defect. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I have a 2006 Nissan Frontier with a V6 engine and automatic transmission. This is a on going problem. The brake pedal is to close to the accelerator pedal. The brake pedal can be depressed lower than the accelerator pedal. This can cause your foot to depress the accelerator pedal when braking. This is especially bad when backing a trailer. I almost hit a tree when backing a utility trailer. It is extremely scary when launching a boat. The truck and driver could end up in the lake. I had two dealers to check the brakes. They say this is normal. One technician thought Nissan had a problem with the brakes on the Frontier not just my truck. I complained to Nissan but didn't receive any help.

The brake pedal is lower than the accelerator pedal. I all most hit a tree because of depressing the accelerator and brake pedals. The owners manual states the brake pedal should be at least 4.1 inches from the floor. My truck is about 3 inches from the floor. The dealer says it is ok. The dealer doesn't know what he is doing. I had trouble getting things repair with this dealer, piedmont Nissan.
