NHTSA Complaint #11424338 — 2014 GMC TERRAIN

I was driving to work during a rain storm. I drove for about 25 minutes until I reached the highway. I merged onto the highway behind a tractor trailer. There was enough spray that I needed to put the wipers on high speed. After driving for a few minutes the wipers came down and stopped halfway. I was able to pull over on the shoulder and tried to determine what happen. I turned wipers off and on and could hear the wiper motor whirring. Motor worked but wipers did not engage. I got out of the vehicle and pushed the wipers down and they moved freely telling me they are not connected to the motor. This was very dangerous and scary! I am now in need of repairing this issue.
