Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

  • 49,000 miles


Truck total mileage is only 55,000 as it is not used very much. 3 issues occurred approx. At 49,000miles. 1) engine started to miss. Upon checking spark plugs it was discovered that the plug cavities in the head were full of oil. The valve cover gasket seals had leaked and the oil filled spark plug holes caused it to miss. This is not covered under warranty so repairs were done at my cost. Had to replace all of the top end valve cover gasket and spark plug hole seals as well as the cam end seals. 2) one day I got into the truck and when I started it up and pressed the brakes the pedal went to the floor. Upon checking the brake master cylinder reservoir it was empty. Found that the rear axle brake line had rusted through and had burst spraying brake fluid all over the spare tire. I have never seen a brake line develop a hole like this. Not covered under warranty and a new brake line and master cylinder was replaced at my own cost.the system had to be bled out and flushed at all 4 wheels. I was very lucky that this did not occur while driving as a crash would have resulted. 3) currently having an issue with the "check engine light" coming on. The code says that it is a emission issue. With the computer code reader I am able to cancel the code and it stays off for a while but comes back on days later. The code is a leaking gas cap but I can detect no leaks and have changed out the cap with an oem cap with same results. Truck runs okay so I have not dug any deeper on this and it is still occurring. 4) while under the truck fixing the brake line issue I discovered that the drive shaft was completely covered with rust. It was never painted from the factory. I had to remove it to kill the rust and paint it with a good coat of black heat proof paint. Corrosion seems to be an issue with these Nissan vehicles.

Frontier 6-cyl

  • 115,000 miles
After driving my vehicle to work (around 15 miles), the lights began to dim and the radio turned on and off several times. I parked in the garage where I work, and went to my office to get in touch with a mechanic. About 1/2 hour later, a police officer called because my truck caught fire. It caused damage to the parking structure, and obviously to the vehicle, including melting many of the components under the hood, as well as smoke damage to the inside of the truck. It was totaled.
