Toyota will be contacting the owners of certain Avalon, Corolla and Matrix cars because of a problem that could result in the air bags and seat belt pretensioners not deploying.
According to the defect report, the affected vehicles may have been manufactured with an airbag control module that does not have sufficient protection against negative electrical transients generated in certain severe crashes where there is a large engine compartment intrusion before deceleration. In these cases, the crash sensor and wiring may be damaged and shorted before the deployment signal is received by the SRS ECU. This would result in incomplete or non deployment of the air bags and/or pretensioners and an increased chance of injury to occupants.

Owners will be notified to return to their Toyota dealer to have a noise filter installed between the airbag control module and its wire harness. In some cases, an inspection may be carried out to determine if a noise filter is necessary before installing it.
