I've had my Commander for 6 months now and I've liked it up until now. I have experienced a little of the whistling but coming from a wrangle I'm used to the noise while driving. About a month ago my "check engine" light went on, although the car was driving fine. About two days later my husband started the car, begain to drive down the street and then it was as if the ABS system kicked in. The car began to jerk and slow down, then it stalled. But it made that sound when you go into a spin and your ABS goes on. Anyway it started back up and we brought it in. Of course they couldn't find anything wrong and gave it back to us. Since then it has happened again(they again couldn't find anything), and my light has come back on a third time. I'm getting nervous to drive it in case it is the braking system. Please let me know if anyone else has had something similar. Thanks
