As I run the simulink code this warning appear,what should I do?

Warning: Unable to reduce the step size without violating minimum step size of
1.4210854715202004E-14 for 1 consecutive times at time 4.0000000000000142.  Continuing
simulation with the step size restricted to 1.4210854715202004E-14 and using an effective
relative error tolerance of 0.013523809523641055, which is greater than the specified
relative error tolerance of 0.001. This usually may be caused by the high stiffness of the
system. Please check the model 'fullcar123' or increase the Max consecutive min step size
violation parameter in the solver configuration panel

[Walter Roberson]

Did you try increasing the Max consecutive min step size violation limit ?
