hello, and welcome. I am a licensed attorney and happy to assist.
Under the Pennsylvania lemon law, you need to contact the dealer about the defect within 1 year or 12,000 miles whichever comes first. Since the clutch problem occurred outside of the window, the lemon law does not come into play. I wish I could tell you otherwise, but having accurate information allows you to make informed decisions going forward.
Since you have a warranty, the dealer must continue to try to repair the problem. Also, check your paperwork because if the problem can't be repaired, the warranty may require replacement of the vehicle, essentially providing much of the same recourse as the lemon law.
I hope this helps. If you need additional information or clarification, just let me know and I'll continue to provide assistance. If I have addressed your issue and/or pointed you in a positive direction, please let me know that, as well. Also, please remember to leave a positive rating when prompted, as that is the only way attorneys on this site are credited for the help we provide.
