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. Notes: The 2008-2011 Mercury Mariner has a dangerous problem with the power steering that Ford says they fixed when they didn't -- at least not 100%.

2008 Mercury Mariner Owner Comments

problem #5

  • 105,000 miles


This had been a great car for me until today. I learned the hydraulic control unit is bad and will require nearly $5000 to replace. It is not safe to drive. It had 105000 miles. It is not worth much more than $5K. I have no choice but to try and trade the car in. I laterally just gave it to my daughter for college on Saturday. She has always loved my car.

While driving my car stalls without warning then it jerks real hard and takes off so I have to ride the brakes after coming to a stop before I can press the gas peddle it takes off so I ride the brakes. While driving again it picks up speed on its own very scare please help.

Took vehicle to Ford dealer to have car inspected was told rotors had to be replaced due to wear brake pads were wearing un evenly car has been serviced by dealer when ever it needed inspection or oil changes uneven wear wasn't seen until warranty had run out the car had lest then 2000 miles on since last inspection. This has happened on other Ford vehicles in past pins that brake pads ride on have always been the cause. They are corroded.
