NHTSA Complaint #11567706 — 2018 RAM 2500

2 months ago my truck started making a “whirling noise” whenever I would turn the steering wheel. There was no change in the ability to steer at all. The service manager informed me it was a “Hydro-booster” issue and was in no way dangerous or would create a danger until an opportunity for service and parts were available. He informed me this was not a warrenty issue and I would have to either leave my truck for “weeks” while part was removed and sent in for inspection or accept noise until I wanted to foot bill for repair of over $1K. I elected to drive with noise until I could save up money and be without my work truck. Recently, driving my truck down the highway and hit a pot hole which created an “out of alighnment” in my steering. Upon arriving home the steering wheel was up to 180 degrees out of snych with steering. As I was backing into driveway and going over the driveway curb I heard a loud “clunking” noise in which my steering wheel then had absolutly no connection with the front tires. I was able to free-spin the column. I had it towed to dealership. Talking to Service Manager, he said it sounds like 2 retaining nuts loosened up to the point of falling off and steering linkage dislodged. Why is there no retaining/ locking pin on these bolting parts to prevent complete separation. I could have been still traveling down the highway when this happened. I feel this should be repaired as a Warranty and I not be charged for this repair.
