Owner reports
Selected complaints filed with NHTSA by 2005 Scion tC owners, lightly cleaned up (personal details are redacted by NHTSA).
1. I believe my airbags deployed pre-maturely with a soft impact to another vehicle. There was no damage to the other vehicle and no police report needed to be filed. There is a minor damage to my front bumper. 2. The airbags inflated on me, but no medical attention was required. 3. I have not confirmed or reproduced this problem with a professional. 4. My car has not been inspected nor reported to my insurance agency as my coverage only covers liability. 5. No symptoms prior to airbags deploying pre-maturely *Because of the pre-mature deployment of my airbags I am unable to afford the airbags to be reset, as doing so would cost more than the kbb estimated value of my car.
Tl* the contact owned a 2005 Scion tC. While the contact was accelerating from a traffic light, her vehicle was t-boned by another vehicle that ran a red light. The entire driver's side of the vehicle was smashed in and the vehicle was totaled. There were no injuries. The side curtain air bags and driver's side air bag did not deploy. A police report was filed and the vehicle was towed to a body shop. The manufacturer was contacted and reminded by the contact that there was an unknown recall for the side air bags for which the vehicle was repaired for in 2006. The manufacturer responded with a letter, stating that they assigned an engineer to diagnose the vehicle. Based on their inspection, they did not find enough frontal damage to command the deployment of the side air bags. The dealer was not contacted. The failure mileage was 91,400.
Takata recall?? Airbags failed, during accident. After being cutoff and going down route x. Lost control hiding concrete. Car flipped, was dragged a few feet's - no airbags. Passenger still has anxiety when getting into vehicles-the one thing you'd think would respond didn't. How do we ever get the sense of security back.
Takota recall. I was recently in a potentially fatal accident and my airbags didn't deploy and I hit my head on the steering wheel pretty hard. I was on the highway and a deer bolted out in front of my car and my initial reaction was to avoid it and ran into a traffic sign and smacked the guard rail going around 50 MPH.
Hi, I was involved in a car accident December 2, 2009. I own a Scion tC 2005 model. I was traveling on highway 440 outer beltline near ext 7 glenwood avenue. It was raining heavily at approximately 6:30 pm when I hit a puddle in the left far lane and began hydroplaning, I hit the car next to me on my passenger side and started spinning approximately 4-5 times and hit the cement barrier on the bridge of crabtree creek. I hit the barrier head on and the spun around again and hit the back drivers side on the cement as well. My car ended against the cement barrier on the far right side of the road facing the wrong direction. My complaint is that my airbags never deployed. Luckily I was not severely injured but hitting head on it is my opinion and that of the owner of the collision repair shop that my car was brought to, that the air bags should have deployed for safety reasons. …
Our daughters 2005 Scion tC was in an accident that was a head on collision she lost control on black ice and hit a pole. Her car has been deemed totaled by the insurance and body shop due to the severe damage to the car. She has numerous injuries from this accident and the air bags not deploying. It is very strange when I called Toyota they claim there are no recalls for airbags which I see in fact there is by this website. They also state that the airbags would not deploy in this type of accident , with her hitting the pole direct and the car being totaled because of the damage how can they say this? They have not even seen the car and over the phone they are stating the airbags would not go off in this type of accident. Sounds like Toyota needs to get their facts straight. …
My son was involved in an accident involving his 2005 Scion tC hatchback. The right front tire left the road and he attempted to correct this. When he corrected, the back end of the car went out from under his control. He crossed the center line and entered the ditch on the left side of the road. He hit a driveway culvert head on. The car then flipped end over end and turned sideways before it landed nose down in a ditch approximately 40 feet from initial impact. Neither the driver or front passenger airbags deployed. He and I have attempted to contact Scion for assistance, they have given us no help. Could you please help us out?
