My car has a recall for the left and/or right tie rod may be bent. A bent tie rod can break, causing a loss of steering control and increasing the risk of a crash. I brought the car in two days prior (July 3rd) to get fixed but the dealership wasn’t allotted enough mechanics to be able to get to my car, (july 5th) I turned out of a hotel parking lot and my front left tie rod broke. The recall number for Nissan is PM985 and is supposed to be fixed by Nissan with no cost to me. At the moment it is under review and Nissan is trying to find any way to not fix it for free.
