General Motors Corporation has determined that certain model year 2005, 2006 & 2007 Cadillac STS passenger cars equipped with sunroofs do not fully comply with Federal Motor Vehicle Safety Standard Concerning Power-Operated Window, Partition, and Roof Panel Systems.
Affected are approximately 60,042 model year 2005, 2006 & 2007 Cadillac STS passenger cars.
GM included an analysis of the risk associated with the subject condition and a detailed explanation of the reasons why it believes the noncompliance to be inconsequential to motor vehicle safety.
In summary, GM states that for all of the subject vehicles:
. The subject condition affects only the sunroof, not the power windows.
. The subject condition requires multiple actions that must occur within a 60 second time period. First, the following sequence of actions must occur: Driver starts engine, driver turns off engine, and driver or front passenger opens a front door. After this sequence of actions and still within the 60 second time frame, occupants must take additional actions: Push the sunroof close switch and position an occupant to create the risk of sunroof entrapment. All of these actions must occur within one 60 second time frame.
. If the sunroof switch is pushed steadily and then released, the sunroof promptly stops moving.
. The sunroof incorporates an auto-reverse system. This system will activate whenever the sunroof is closing in the express close mode. Therefore, sunroof entrapment requires the completion of the initial sequence of engine start/engine stop/front door open actions, and also requires an occupant to press and hold the sunroof closure switch and position an occupant within the sunroof--all within the 60 second window and in such a manner that the auto- reverse is not effective in preventing sunroof entrapment.
