It’s no idle boast, especially as many lithium-batteries are said to have a maximum life span of around 7-8 years, yet until now Hyundai hadn’t released any specifics on its lifetime warranty for the Hyundai Sonata Hybrid’s battery pack.
As result, there’s been much speculation in regards to exactly what this battery warranty covers and doesn’t cover, though Hyundai, in an attempt to address these rumors has finally set the record straight.
In a statement issued from the company, it declared that, “the Hyundai Lifetime Hybrid Battery Replacement Guarantee ensures that if the 2012 Sonata hybrid lithium-polymer battery fails, Hyundai will replace the battery and cover recycling costs for the old battery pack free of charge to the original owner. The coverage is not transferable, and does not apply to lease and commercial vehicles or vehicles serviced outside the U.S.”
Note how the above doesn’t mention the battery system’s integrated hardware, software and controllers. These are covered by a warranty, though in this case it’s the Sonata’s Powertrain warranty which is good for 10 years or 100,000 miles, which ever comes first.
Hyundai’s US CEO John Krafcik, has already stated that Hyundai is able to offer the battery warranty because after extensive durability testing, failure rates for the battery system have proved to be minimal.
That said, if owners do experience major battery failure on their Sonata Hybrids, they might want to consider the car’s mileage and condition before looking to cash in on the warranty program, as depending on the circumstances, it could still work out to be quite expensive.
