HANKOOK KINERGY GT H436 BW TIRES Complaints

2025 Camry was dealer serviced at recommended internals. At the 24,000 mile service vehicle there was a "hum" from the front of the vehicle, and returned to the dealership. They confirmed the tires that had been on the back were moved to the front during the regular rotation and confirmed "consistent cupping on all 4" tires. The dealer informed us that all 4 Hankook Model Kinergy required replacement. The dealer would not provide a firm cause response. I asked for the alignment check and they confirmed it "was in spec at each visit and provided the report. The dealer inspects alignment and pressure at each visit and there were no findings of out of range. There is no warranty offered to the consumer on OEM tires, and the dealer provided an estimate for replacement in between $925 (same model which will absolutely not happen) and $1,250 for an alternate brand. In researching this issue, there are numerous reports of Hankook Kinergy GT tires OEM mounted and serviced failing between 5,000 and 24,000 miles, well below the warranty period. The arrangement between Toyota and Hankook does not support "tread wear" warranty and the only avenue for the consumer is full out of pocket replacement. When this information was passed along to the dealer, they asked for additional information and have agreed to "work with me" on cost of replacement and have requested a return visit to photograph the vehicle to submit a warranty claim. A Simple web search identifies a high instance of issues with this tire including a at least one safety recall due "tread separation potential". After presenting the dealer with the complaints filed and background, they have agreed to submit a warranty claim with Hankook but advised this will not likely provide relief. Regardless, these tires have documented failures in as little as 5,000 miles. And cupping/wear on all four wheels before the 4th service interval. Someone is going to be injured or worse. This needs a review!

While driving down the highway, the whole car and steering wheel of 2021 Toyota Camry Hybrid started shaking side to side. Was able to exit safely and found a bubble in the sidewall of the 2021 Hankook Kinergy GT H436 BW 235/45R18 tire. Never had this happen with any tire before. 31,000 miles on tire. Could have caused a blow out if the exit was further away. No notification on Toyota Camry Hybrid screen or dash that anything was wrong with the tire before failure. I will check if the tire center will inspect the tire for me when they replace it in a few days.

A Honda 2019 CR-V EX 2WD was purchased in March of 2019 and came with OE Hankook Kinergy GT 235/60R18 H436 tires. The DOT# 5M3V1BH5018 (One tire) and 5M3V1BH5118 (Three tires). The vehicle was garage kept and most of the mileage driven was within the state of Tennessee. All four tires were rotated every 5,000 miles and balanced every 10,000 miles by the Honda dealership that sold the vehicle. A multi-point inspection was performed every 5,000 miles that included steering, braking, struts, and suspension components with no issues found. Tire pressure was monitored by both the owner and dealer during routine maintenance. Road noise began after the 12,000-mileage maintenance and could be seen as uneven tire treadwear. At 15,000 miles the dealership performed a four-wheel alignment to correct the problem, but the noise continued and became more pronounced at higher speeds. It became difficult to hold a conversation or listen to the radio without turning up the volume. By 23,000 miles it became apparent that the inside and outside tread on all four tires had become scalloped. The dealership confirmed the diagnosis and recommended new tires. They stated that continuing to drive with the cupped tire tread was not a safety issue. In contrary, most retail tire or automobile repair websites universally agree that driving with scalloped tires is dangerous. The decreased amount of tire tread to road contact causes reduced traction and increased braking distances, on wet driving surfaces and in emergency situations. The dealership service advisor also shared information that Hankook uses substandard material in the manufacturing of their OE tires leading to premature wear and possible failure. How does this tire justify a treadwear rating of 540 and mileage warranty of 70,000 miles when an entire set of four tires became useless and unsafe at 15,000 miles?

Purchased brand new Honda 2018 and it came with Hankook 235/60R18 KINERGY GT H436 BW At 30,000 miles all 4 tires need to be replaced. Honda manufacturer and dealer confirmed that this is a known issue. I contacted Hankook manufacturer and was told that although the 235/60R18 KINERGY GT H436 have a 70,000 mile warranty, the 235/60R18 KINERGY GT H436 tires that come with the new car are designed to only last 30,000 miles out of the usual 70,000. Hankook deliberately engineered their tires to fail at 30,000 putting my life and the life of my family in danger in order to generate a profit. When purchasing my new car I was under the impression (based on the Hankook manufacturer's website) that my new tires would be covered by the 70,000 mile warranty and would thus last more than just 30,000. All my other new cars, the tires lasted well over the warranty that they initially came with. This is the first time that I have ever experienced this. This clearly has nothing do to with my driving pattern, considering that the manufacturer CONFIRMED that they engineer new car tires to FAIL at 30,000 miles.
