- Do you receive warning and/or error messages? If so the full and exact text of those messages (all the text displayed in orange and/or red in the Command Window) may be useful in determining what's going on and how to avoid the warning and/or error.
- Does it do something different than what you expected? If so, what did it do and what did you expect it to do?
- Did MATLAB crash? If so please send the crash log file (with a description of what you were running or doing in MATLAB when the crash occured) to Technical Support using the Contact Support link on the Support section of the MathWorks website so we can investigate.

Which line is line 15? Don't make us guess or count, tell us.
What does "does not work" mean?

If you inspect your variables before plotting, you will find that y is a single column.
plot(t,y,'-');%this will work in your current code, but you were expecting plots for wheel and car and are only getting one.
