Yahoo Autos Some Hyundai Palisades recalled over valvetrain problem
Hyundai has issued a safety recall that applies it over 4,000 units of the Palisade built during the 2024 model year. The SUVs included in the campaign could experience a valve spring failure, a problem that can cause major engine damage including puncturing a hole in the block.
Assigned recall number 24V-106 by the National Highway Traffic Safety Administration (NHTSA), the recall includes 4,245 units of the Palisade built between August 21 and October 12, 2023. The company estimates that the defect is only present in 1% of these vehicles.
It's a serious one, though. Hyundai told the NHTSA that the valve springs were damaged during manufacturing, which is handled by a third-party supplier, and that they can consequently "fracture while driving due to fatigue cracking." If you need a refresher course, the valves let air into the engine and allow exhaust gases out. The springs open and close the valves while preventing them from dropping into the cylinder. As noted in Hyundai's documents, a fractured valve spring can cause "a sudden loss of motive power" without prior warning.
