Transport Canada Vehicle Recalls & Defects Database Transport Canada Recall # 2007169 Recall Date:  2007/05/30 Notification Type:  Recalls Audit System:  Airbag Manufacturer Recall Number:  G09 Units Affected:   51,000 Category: Minivan Recall Details: On certain vehicles the left or right front supplemental airbag sensors may crack under certain conditions, which can allow water to enter into the sensor. This can cause the airbag warning lamp to illuminate. A malfunction of one or both of the supplemental sensors will not adversely affect safety or cause a failure to comply with government standards. The single-point sensor in these vehicles, which is located in the airbag control module, is operational even if both supplemental sensors are inoperative. DaimlerChrysler has decided to launch a Customer Satisfaction Notification to advise customers that these front airbag sensors will be replaced with redesigned sensors to reduce the potential for damage. This action is not being conducted under the Motor Vehicle Safety Act.
