This has zero to do with the lawsuit and everything to do with CA emissions control laws! In CA, for any car that was originally sold in CA, emission-related parts are warranted for 8 years and 82,000 miles. If you have a CA car, look in your maintenance book -- it's right there.
Emissions warranties in other states vary -- you need to check your state.
BTW, injectors are "emission related parts" in CA as well.
