I think there is some confusion here. A certified used car is checked for a lot of different things before it can be sold as such but that doesn't give it an additional warranty, just that it's been certified. A warranty is an add on to a dealer's warranty for a longer period of time, several years past the dealer or manufacturer's warranty.
Yes there is some confusion. A Honda Certified Pre-owned vehicle gets: (from Honda Website)
Every Honda Certified Used Car goes through our certification process to make sure it lives up to Honda's high standards. And only well-maintained Honda vehicles are eligible for certification, a process that includes:
* An exhaustive 150-point mechanical and appearance inspection, performed by the dealer technician, in which all major vehicles systems are scrutinized, including breaks, engine, drivetrain, steering, suspension, tires, wheels, exhaust system and vehicle interior and exterior.
* A process where Honda-trained technicians recondition any component that does not meet our standards, or replace it with Genuine Honda parts. All scheduled maintenance services are brought up-to-date.
* A free CARFAX Vehicle History report to assure that your Honda Certified Used Car does not contain any DMV-reported incidents such as salvage, fire, flood damage, odometer problems or lemon history.
The Warranty is then extended, from THE MANUFACTURER (HONDA), not a third-party warranty company. BTW-- even "Honda" extended warranties (other than certified) are third-party warranties.
From Honda:
Every Honda Certified Used Car comes with peace of mind: one of the most extensive used-car warranties in the business. So you can drive off the lot feeling confident about your purchase. These warranties cover:
* Major engine and transmission components, except for standard maintenance items, body glass and interior.
* The repair or replacement of any covered part that is defective in material or workmanship under normal use. With a $0 deductable.
* Powertrain coverage for 7-years/100,000-miles (whichever comes first) from the vehicle's original in-service date.
* Non-Powertrain coverage for 12-month/12,000-miles (whichever comes first) from the original warranty expiration date, or if the original warranty has expired, from the Honda Certified Used Cars purchase date.
The certified Warranty EXtends the manufacturers warranty. Lots of dealers sell "certified cars with warranty, but it is from the dealer and a third party, not the manufacturer. Similar programs exist for other manufacturers for Toyota, Nissan, Lexus, Infiniti, BMW, etc. Make sure it is a Manufacturer Certified and not Dealer Certified.
