The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling.

“THE 1ST THING I NOTICED AFTER STARTING MY CAR AFTER WORK WAS THE HEATER WAS BLOWING COLD AIR, EVEN AFTER 4 MILES ON THE ROAD (2 LANE ROAD - 40 MPG). ABOUT 4 MILES FURTHER ON (FREEWAY - 60+ MPH), I NOTICED A THIN GREY CLOUD BEHIND ME, BUT THE EVENING MISTS WERE EVIDENT, SO I WASN'T SURE AT FIRST IF IT WAS COMING FROM MY CAR. I CHECKED THE TEMPERATURE GAUGE WHICH SHOWED FLAT COLD - UNUSUAL! I CHECKED MY REARVIEW MIRROR AGAIN, MAYBE 200 YDS LATER, AND THERE WAS A PALER GREY CLOUD FOLLOWING ME. I CHECKED THE INSTRUMENT PANEL AGAIN AND THERE WERE NO WARNING LIGHTS SHOWING. ABOUT 200-500 YARDS FARTHER, THE VSC LIGHT CAME ON, THE TRACTION CONTROL LIGHT CAME ON AND ANOTHER LIGHT THAT IS NOT SHOWN IN THE OWNER'S MANUAL STARTED BLINKING: THE SYMBOL WAS A CAR WITH A RECYCLE ARROW INSIDE THE BODY. I TOOK IT TO MEAN THAT THE CONTROLS WERE ACKNOWLEDGING THE HEATER WASN'T WORKING (THE SYMBOL IS THE SAME AS "AIR INTAKE SELECTOR" ON THE HEATER/AIR CONDITIONER CONTROLS). I FELT THAT I STILL HAD GOOD CONTROL OVER THE STEERING; IT WAS A CLEAR EVENING AND THE ROAD WAS DRY, SO I FELT I COULD GET HOME SAFELY (2 MILES). THE CAR WAS RUNNING QUITE ROUGH WHEN I GOT HOME AND THERE WAS…”

“I am writing to report significant safety concerns regarding my 2008 Scion [include model, e.g., tC or xB]. After purchasing the vehicle, I discovered multiple serious mechanical and structural defects that make the car unsafe to operate on public roads. 1. Suspension/Struts – The struts are severely worn and are causing premature and uneven tire wear. This creates a major risk of tire blowout or loss of control while driving. 2. Motor Mount – The engine mount is missing screws and bolts, which results in excessive engine movement. This could lead to engine damage or failure while in motion. 3. Alignment – The vehicle’s alignment is completely off, causing the car to pull while driving and further worsening tire wear and handling. 4. Brakes and Rotors – The brakes are nearly nonfunctional, and the rotors are warped and damaged, severely reducing stopping power and increasing the risk of a crash. 5. License Plate Mount – The vehicle has no designated place to mount a rear tag/license plate, which makes it illegal to drive and difficult to comply with state requirements. 6. Missing Headlight – One headlight is entirely missing, significantly reducing visibility…”
