Approximately 16,300 of the Alabama-built units could be affected, although there have been no official complaints, injuries, or accidents yet. According to the NHTSA, the intermediate steering shaft assembly upper universal joint could potentially fully detach and a cross-threaded pinch bolt could strip upper universal joint connection threads. Both these issues could lead to a loss of steering control.
Regulators also mentioned the steering problem could lead to a compromised brake system, a case in which the shaft drops out and could hinder brake application. Thankfully, this is being caught and handled early on.
At the moment, it is not confirmed if only US-built Hyundai Sonatas are affected.
