Tire Problems of Hyundai Palisade

Tire size: 245/50r20 102v. All four original equipment tires (hankook ventus s1 noble2 h452) developed sidewall failures at approximately 29,000-30,000 miles of normal driving. All four tires showed identical diagonal stress cracking across the upper sidewall, consistent with sidewall flex fatigue. One tire showed visible outward bulging/deformation of the sidewall, indicating internal structural separation. Two tires had areas of outer sidewall rubber torn away with internal cord material exposed. No warning light appeared prior to discovering the damage upon visual inspection. This presented a serious safety risk, as a sidewall in this condition can rupture suddenly at highway speed, causing sudden air loss and potential loss of vehicle control. The vehicle was used for daily driving, including with family passengers, before the damage was found. The tires were inspected and replaced by an independent tire retailer, who confirmed all four required replacement. The vehicle has not yet been inspected by the manufacturer, police, or insurance. This same tire model was previously subject to an NHTSA recall (campaign 15t024) for sidewall cracking on a different size/application, and there is a documented pattern of similar consumer complaints describing sidewall cracking and failure on this tire line, including on other Hyundai models. These were original equipment tires with no known prior impact, collision, or unusual road event before the damage was discovered.
