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.

Left front lower front control arm started to collapse due to severe rust through. There was no warning, only a sudden creaking and groaning noise and sone difficulty turning the wheels while driving home on country roads. Earlier in the day, we had been on the interstate traveling at 65 mph. If this control arm fully fractured at that speed we would have lost all steering ability, this car has only 26363 miles on it.

Passenger side rear suspension strut (spring/shock assembly) suddenly collapsed downward because lower spring retainer ring rusted away, allowing suspension spring to push downward and up against rear tire. Happened when we were pulling out of driveway, first heard a thump, followed by a dragging sound and then saw blue smoke coming from rear passenger side wheel well. At first we though a tree branch had gotten caught under the vehicle (we live in a rural area). Vehicle had to be towed from driveway for repair. Had this happened suddenly on a highway at 55 mph or more we may have lost control of the vehicle. Examination of the strut on the rear driver's side showed it also was significantly rusted and no doubt it too would have collapsed at some future point. Both rear struts and damaged tire replaced by local repair shop.

The driver's side rear suspension trailing arm, which attaches to the frame and rear wheel assembly suddenly sheared away due to rust through. The purpose of the trailing arm is to keep the rear wheel ridged and prevent it from moving backwards or forwards. Even if the trailing arm did not drop to the ground, the car may not handle properly, especially at high speeds, with a rear wheel acting like a loose cannon. Since the break was near the point where it attached to the frame the implications are enormous. If the arm were to drop to the ground while the vehicle was in motion, especially at highway speeds, it could push the entire rear wheel assembly back and cause a loss of vehicle control. Worse, it could also cause the car to jackknife up resulting in loss of control.
