AIR BAGS:FRONTAL:PASSENGER SIDE:INFLATOR MODULE
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2008-2011 Scion xB and Lexus IS F, 2009-2011 Toyota Corolla and Corolla Matrix, 2006-2011 Toyota Yaris, Lexus IS250 and Lexus IS350, 2010-2011 Toyota 4Runner, Lexus IS250C, Lexus IS350C and Lexus GX460, 2011 Sienna, 2007-2011 Lexus ES350, and 2009-2010 Pontiac Vibe vehicles, originally sold, or ever registered, in Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands (Saipan), and the U.S. Virgin Islands, or "Zone A." Additionally, unless included in "Zone A" above, Toyota is recalling certain model year 2008 Scion xB and Lexus IS F, 2007-2008 Toyota Yaris, 2006-2008 Lexus IS250 and Lexus IS350 and 2007-2008 Lexus ES350 vehicles, originally sold, or ever registered, in Arizona, Arkansas, Delaware, District of Columbia, Illinois, Indiana, Kansas, Kentucky, Maryland, Missouri, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Virginia, and West Virginia, or "Zone B." Vehicles of these model years and models that were not originally sold or ever registered in either Zones A or B are not subject to this safety recall. These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules, and used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the front air bags, these inflators may rupture due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.

Regular maintenance following the manufacturer's schedule helps prevent many common problems.
Repair costs for known Toyota Matrix issues range from $0 to $4,500, depending on the specific problem and whether you choose DIY or professional repair. The most critical issue, SRS Airbag Control Unit Short Circuit Causing Inadvertent Airbag Deployment (Recall 15V043), typically costs $0-$0 to repair. Au7o provides step-by-step DIY maintenance guides that can help reduce repair costs.
The supplemental restraint system electronic control unit fitted to 2003-2004 Corolla and Corolla Matrix vehicles was built with integrated circuits susceptible to internal short circuiting when exposed to electrical noise from other vehicle systems. The consequence is severe and… Repairs typically run $0-$0. Severity: high.

VEHICLE SPEED CONTROL:ACCELERATOR PEDAL
TOYOTA IS RECALLING CERTAIN MODEL YEAR 2008-2010 HIGHLANDER, MODEL YEAR 2009-2010 COROLLA, VENZA AND MATRIX PASSENGER VEHICLES. THE ACCELERATOR PEDAL CAN GET STUCK IN THE WIDE OPEN POSITION DUE TO ITS BEING TRAPPED BY AN UNSECURED OR INCOMPATIBLE DRIVER'S FLOOR MAT. THIS RECALL IS AN EXPANSION OF A CAMPAIGN OF 3.8 MILLION OTHER TOYOTA VEHICLES ANNOUNCED IN 2009 FOR THE SAME ISSUE (SEE 09V-388).

The 1.8L 1ZZ-FE used in the base, XR and AWD Matrix (and the identical Pontiac Vibe) through the early first generation uses a narrow, low-tension oil-control ring package whose drain slots coke over with carbon. Once the rings stop draining, oil is pumped past them into the comb… Repairs typically run $1,800-$4,500. Severity: high.
The Matrix is caught in multiple phases of the Takata inflator campaign because it used non-desiccated ammonium nitrate inflators across both generations. The propellant degrades with long-term exposure to heat and humidity cycling; on deployment the inflator housing can rupture… Repairs typically run $0-$0. Severity: high.
The Matrix XRS uses the high-revving 2ZZ-GE with VVTL-i, an engine shared with the Celica GT-S and Lotus Elise. Two related weaknesses are documented by owners: the Matrix/Corolla XRS oil pan lacks the internal baffle the 1ZZ-FE pan has, so during sustained cornering or a low oil… Repairs typically run $150-$3,500. Severity: high.
1st-gen Matrix models are prone to rust at the rocker panels, rear wheel arches, and rear hatch seam areas in salt-belt regions. The rust starts from inside the rocker panel and works outward, often being severe before it becomes visible on the exterior. Repairs typically run $100-$1,500. Severity: medium.
On the all-wheel-drive Matrix and Pontiac Vibe of the first generation, a speed-dependent hum or growl from the rear is one of the most commonly reported complaints - and one of the most commonly misdiagnosed. Toyota published a tech bulletin on abnormal noise from the rear diffe… Repairs typically run $150-$1,400. Severity: medium.
Coolant appearing under the front passenger side of the car, often as a dried pink or orange crust rather than a puddle, is one of the highest-frequency Matrix repairs across both generations. The mechanical water pump's shaft seal fails and coolant weeps from the pump's weep hol… Repairs typically run $250-$650. Severity: medium.
On sunroof-equipped Matrix and Vibe models the glass panel seal is deliberately not watertight - water that gets past it is supposed to run into four corner drains and out through tubes routed down the A- and C-pillars. Tree debris, pollen and dirt block those drains, or a tube p… Repairs typically run $0-$400. Severity: medium.
P0420 is among the most frequently reported check-engine complaints on the Matrix and its Pontiac Vibe twin. On these cars it is rarely a converter that simply wore out in isolation. Two upstream causes dominate: the aged downstream oxygen sensor whose switching becomes too lazy… Repairs typically run $150-$1,400. Severity: medium.
The rear hatch lift support struts lose their gas charge, causing the hatch to fall or not stay open. This is a common issue on all Matrix model years, typically failing between 5-8 years of age. A falling hatch is a safety hazard. Repairs typically run $30-$80. Severity: low.
Matrix rear hatch gas struts lose pressure over time, causing the hatch to fail to stay open and drop unexpectedly. This is a common issue on both generations, typically occurring between 5-8 years of age. The failing struts create a safety hazard as the heavy hatch can strike th… Repairs typically run $30-$100. Severity: low.
The first-generation Matrix (2003-2008) is notorious for water leaking into the rear cargo area through deteriorated taillight gaskets. Water pools in the spare tire well and can damage the cargo floor, cause mold/mildew, and corrode the spare tire hardware. The taillight mountin… Repairs typically run $20-$100. Severity: low.
The heater and air conditioning blower on the Matrix runs through a resistor pack that drops voltage for the lower fan speeds; the highest setting bypasses it entirely and feeds the motor directly. When the resistor burns open - the classic failure on this platform - the fan work… Repairs typically run $60-$400. Severity: low.
