Her mechanic could not address either problem.thank you

There are codes stored in the car’s computer. Most auto parts stores will “read” the codes as a free service. Post the error codes and you will get responses explaining what they could mean.

I’m not too impressed with the mechanic who could not address the problem, time to find a better shop. What has “date of purchase” got to do with anything? It seems to have no relevance to the question?
