As long as you make your payments on time, it is not risky to have a cosigner on your loan. In fact, the cosigner is the one who assumes all of the liability if you default on your loan. This means that it is actually more risky for the cosigner than it is for you. That being said, defaulting on a loan could cause friction in your relationship with the cosigner if they have to deal with damage to their credit and/or out-of-pocket expenses.
