The best warranty on a ICE car in the USA is from Hyundai Kia it’s 10 years or 100000 miles which ever comes first. Tesla gives a 8 year or 120,000 mile battery warranty. The big three Ford, GM nor Dodge give 10/100Ks they are all 60k or less. Standard warranties. Kia is always 10/100 and every Tesla other than the base 25k model 3 has an 8/120. Personally I have never kept a car past 4 years let alone 8 so it’s moot. Even on a five year note for suckers there would still be 3 years left. Why people finance cars is beyond me it’s a depreciating asset the day you drive it off the lot. Save the money up front in an investment instrument make it earn you money then cash it out pay the cash price on a 1 year old vehicle with under 20,000 miles and let some other sucker pay the drive off depreciation.
My current car is ~15 years old. I haven’t had any big repair bills. I had an all wheel drive fluid pump fail during a polar vortex about 5 years ago. Fortunately, there was a hidden warranty that covered the repair. My big expense has been insuring it.
