How can I stop Navmesh agent sliding?

Try setting the acceleration to be a high number such as 60. Note that navMeshAgent stop its force at that location but will still move forward due to inertia. A high acceleration will make it stop very close to that exact location

turn auto braking off

I'm seeing that this is STILL an issue in Unity 5. For anyone who is still experiencing this issue, here is a solution that works for me:

   public float acceleration = 2f;
   public float deceleration = 60f;
   public float closeEnoughMeters = 4f;
   private NavMeshAgent navMeshAgent;
 
   void Start()
   {
     navMeshAgent = gameObject.GetComponentInChildren<NavMeshAgent>();
   }
 
   void Update()
   {
     if (navMeshAgent)
     {
 
       // speed up slowly, but stop quickly
       if (navMeshAgent.hasPath)
         navMeshAgent.acceleration = (navMeshAgent.remainingDistance < closeEnoughMeters) ? deceleration : acceleration;
 
     }
 }
 
 

in my case, setting acceleration to 60 does not work. so i have to create another solution like this.

 if (Vector3.Distance(target, transform.position) < navMeshAgent.stoppingDistance)
 {
 navMeshAgent.SetDestination(transform.position);
 }
 else
 {
 navMeshAgent.SetDestination(target);
 }
 

I got the Same Issue but my character was slipping while turning. This works for me. Increase "Acceleration" and increase "Angular Speed". Values for my Character Speed=30 Angular Speed=300 Acceleration=140
