While test driving a volkswagon Passat glx sedan, touching the window control caused the ABS braking mechanism to engage. The car lurched as if the brakes were quickly applied and ABS failure warning lights and tones went off in the car. The instrument lights flickered as well. The warnings shut off in a few seconds and the car appeared to return to normal. This happened on two seperate occasions in the span of 10 minutes both times while traveling on a level road at a constant speed with my foot on the accelerator at the time. The situation was dangerous because of the unintended braking and the startling effect of the warnings occuring simultaniously.
