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.

Another vehicle stopped directly in front of me, hitting the front of my car with force. Then that car abruptly left the scene. The airbags did not go off and I was severely jolted. Then the car went up in flames. I was in a state of shock and confusion. Left the scene and ran home as my body was in turmoil. I had to use the bathroom immediately. I then called the police. Regarding the accident. The other car has still not been found. Progressive is my insurance. The car was towed to a lot in turnersville, N.J. my insurance company has all the information.

The contact owns a 2010 Subaru Legacy. While reversing out of the driveway, another vehicle driving at approximately 55 mph crashed into the front driver's side door of the contact's vehicle. The air bags failed to deploy. The driver sustained lacerations to the head, hematomas, amnesia, stuttering, damage to the nervous system, and severe head injuries. The injuries required medical attention and caused the contact to become an epileptic. A police report was filed. The vehicle was towed to a dealer where it was not diagnosed nor repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 37,000.

Passenger air bag light indicating air bag is off when a 5'4'' 112 pound adult female is in the seat. The indication light will sometimes flicker from off to on but mainly remains off for the duration of the drive regardless of the speed as well as when the car is in park. This incident has occurred since the purchase of the car in June 2011 and continues to occur each time my wife is in the passenger seat.

The passenger-side air bag in our 2010 Legacy is turning off intermittently and spontaneously while the car is in motion, although the passenger seat is occupied by a 120-pound person. The bag is deactivating even though the seat is securely locked into position as far from the dashboard as it will move, and nothing is placed beneath the passengers seat. To reactivate the air bag, it is necessary to stop, then to restart the engine, and that maneuver is frequently not feasible in either heavy freeway traffic, or on remote highways that lack shoulders. The rebooting procedure indicates that the problem is not any sensor for the seat it is a problem with the computer operating the air bag. The dealer is unable to treat this problem.

The 2010 Subaru Legacy GT has a defect in the sensor that determines weight in the passenger seat. This sensors function is to turn the airbag on or off depending on the amount of weight in the seat. With a 114 pound woman in the passenger seat, the automatic airbag sensor does not signal for the airbag to be ready to deploy and continues to be in the off mode. After taking the vehicle to multiple Subaru dealerships, I was informed that the needed weight to turn the airbags to the on mode was 17 pounds. My 114 pound wife is far more than 17 pounds but the airbag sensor still does not trip to the on mode. I am worried that a passenger will not be protected in a possible crash.

Front passenger airbag works intermittently. Purchased new 2010 Legacy from hudson Subaru jersey city in Mar 2010. Front passenger airbag light is frequently off when I am sitting in seat (5'7" & 135lbs). Is properly activated half of the time. Tried many things to get airbag to turn on including: 1. with car running, unfastening passenger seatbelt and refastening 2. with car running, opening passenger door, exiting car and getting back in 3. exiting car, shutting car off, restarting car and getting back in 4. with car running lifting myself up and off seat and sitting back down as hard as possible. Husband took car to hudson Subaru on 11/9/10 and they recalibrated seat module and sensor. Problem persisted so he called hudson Subaru on 10/12/11. Said they have received a number of calls regarding this issue, but that there is nothing they can do. Sensor is designed to activate airbag when 90lbs of pressure is applied to seat. If a smaller person is not sitting squarely in seat, sensor may not detect persons weight and airbag will not be activated. Called Subaru on 10/12/11 and opened a case. Also emailed Subaru on 10/20. Received email reply on 10/26 requesting I bring car to dealership and meet with a field rep. On 11/1 rep indicated weight setting is not 90lbs its closer to 112lbs. Said he met with a couple in flemington having same issue and had to replace gel bladder in seat. He asked to see car and checked to be sure seatback not reclined and then asked me to sit in car. Pointed out that backs of my thighs did not touch seat and suggested my full weight was not being detected by sensor. He kept car overnight and performed different tests, but was unable to replicate problem. He emailed me a page from owners manual which detailed how someone should sit in seat and steps an owner should take if the airbag does not activate.
