While at highway speeds vehicle braked unexpectedly due to what seems to be a malfunction in the front collision warning radar. This resulted in a multiple near miss collisions coming from the rear, for many vehicles on I5 near woodburn or during high traffic times. The vehicle suddenly braked causing me to swerve off the road. Other vehicles includes two immediately following, there was a vehicle 6-8 car lengths ahead traveling at the same rate of speed with no braking, both sides were clear of traffic, no damage done seeking dealer assistance to decipher exact cause. Vehicle continues to have all safety features automatically turned off from computer. Vehicle was traveling straight with no braking needed nor wanted.
