I have a few more months till the warranty is over and was wondering if you guys think it'll be worth it to extend?

I think it costs about 2k for another 2 years or so. Car has been taken for pretty will with synth oil, maint, etc, so I don't forsee really bad things happening when I run out of insurance, but you'll never know.

Any major issues that's been happening to people after their 35/40 miles? Should I extend it?

 

Your powertrain warranty is good for 70 months/60,000 miles (I think this is correct, it's at least close, but I can't remember exactly), so no need to get a full warranty extension. If you can find one that will cover the electrical components, that may be worth it.
