Mahindra XUV300

After first service of 1000km, Suddenly my new car Mahindra XUV300 steering gets very hard and not able to move steering, with steering yellow light indication.This is very critical issue of steering gets super hard, almost like steering lock.And the Mahindra service centre is not able to diagnose the issue even after one day at service centre.This can cause a big accident in actual situation if it gets hard suddenly,very disappointed.
