My friend is having trouble with his car. What do you think is wrong with it?

I’m not sure what the exact problem is, but I can tell you that there are a few common issues that could cause this type of issue. First, check to make sure all of your fluids are topped off and that your oil levels are correct. If they are, then check for any signs of engine damage, such as smoke or burning smells coming from the engine. You may also want to have a qualified mechanic take a look at the car and diagnose the problem.
