While traveling in a straight line at a constant velocity, my car applied braking force to the front left (driver's side) wheel, rapidly and suddenly. The bas esp light then came on and remained on for the duration of the drive.

Car: 2000 Mercedes C230 kompressor driving at 55mph, the car's front right brake suddenly engaged causing the car to loose control for a moment. The brake then releases and the bas/esp light illuminates. This has happened 5 times in the last week. This situation is extremely dangerous!!!!!! I have researched the issue and the dealership is telling me it is the yaw rate sensor or steering position sensor. The fix is $1100. This is a total safety issue on this car and after researching online in various forums there are numerous owners in both the C and ml class vehicles (they use the same exact same part numbers) that experience this problem. Please please please take time to look into this. There are a lot of these cars on the road and this can and will cause major accidents!!!!
