#1 Chevrolet Protection Plan is the extended warranty
Since I live South of the border I'm used to thinking in miles. I'm going to need my calculator.
If I'm converting properly, 100,000 Kilometers = a little over 62,000 miles. So 7 years or 62,000 miles. If you don't drive a lot you could be covered for 7 years. I drive roughly 12,000 miles (19,312 kilometers) per year so that warranty would only last me a bit over 5 years. So not great for me but could be good for you.
You should have a contract that looks like this: https://www.chevrolet.com/content/dam/chevrolet/na/us/english/index/owners/warranty/06-pdfs/CHVSC_230524_SAMPLE.pdf
It lists everything that is covered and what isn't.
#2 Chevrolet Pre-Paid Maintenance basically means you paid up front for a specific number of oil and oil filter changes and tire rotations.
I do my own maintenance so I haven't read the specifics of this plan. I was able to find a sample contract. You should have been given a contract that looks like this: https://www.chevrolet.com/content/dam/chevrolet/na/us/english/index/owners/warranty/02-pdfs/chevrolet-pre-paid-maintenance-sample-contracts-2-10-2022.pdf
It should say how many oil changes you paid for.
If it were me, and I was only driving about 14,000 kilometers per year, I would change the oil twice per year. So if you bought a 7 year (84 month) plan I would think your contract would be for about 14 oil changes.
I included links to sample contracts for reference but I highly recommend reading the contracts you were given carefully and make sure they will work well for you.
Now for my fine print; I can't guarantee my conversions are correct. Everything here is opinion and should be treated as such. I do not claim to be a professional (anything) nor do I claim to be intelligent.
