Waste of money. Length of hybrid system, hybrid battery, warranties varies by state mandates but most any state that follows California emissions and warranty standards (we live in NY which is California compliant), those states mandate minimum hybrid battery and related hybrid parts coverage at 10 years/150,000 miles, some manufacturers offer this hybrid warranty in all states (not sure about Kia) and as we know Hyundai has lifetime hybrid battery warranty.
Many automobile extended warranty companies have gone bankrupt over the years leaving consumers out in the cold. There are also very tight restrictions, ifs ands and buts, to getting coverage, and you MUST be religious about keeping, yes keeping your paper records, invoices, receipts regarding your strict adherence to ALL maintenance, and it MUST be done at the exact time/mileage intervals recommended in the owners manual. They will look for anything to get out of covering a costly repair.
Had these warranties existed in the 1970's when buying a reliable vehicle was near impossible, it would have been a good option. In today's consumer driven world automobile reliability has gotten to the point where we can expect 200,000 - 300,000 miles out of ANY of the big name manufacturers before major repair work due to failure is required.
