<human>:  How can I tell if my car is having trouble?
<bot>: If your car is having trouble, you may be able to tell by paying attention to any unusual sounds or smells, as well as any changes in performance like decreased power or acceleration. You may also notice warning lights on the dashboard, or check your car’s diagnostic system for any error codes. If these signals persist, it would be a good idea to take your car to a qualified mechanic for further inspection.
