HANKOOK TIRES Complaints

The contact owns a 2025 Ford E-350 equipped with Hankook Tires, Tire Line: Dyna Pro HT, Tire Size: 245/75/R16, DOT Number: 00TL5CHHA 1224, and DOT Number: 1BCl5CHHB 2725. The contact stated that while driving 50 MPH, the sidewall started to detach. The vehicle was not load rated, and there was a blowout. The tires were replaced with underrated tires. The dealer informed the contact that the vehicle had driven over an unknown object on the roadway. The tires were replaced. The vehicle manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 37,000.

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!

I went into the Nissan dealer with my Nissan Pro4x with 900 miles on with a lowspeed "thunking" sound coming from the rear end. On the highway the truck vibrates really bad at about 60-65 mph. The dealer (NUCAR Nissan of Allentown, Pa (484)223-0564, service writer Simone) inspected the vehicle and "road force balanced" the rear tires. Both rear tires were found to be bad.....900 miles on the vehicle! The dealer (Simone) claims they do not warranty tires, "Call Hankook", they told me. I called Hankook they provided me a reference number #[XXX] and told me they only deal with the dealer service department. I went back to NUCAR Nissan of Allentown, Pa. They (Simone) again told me they can't help me with warranty tires?!! This is an unsafe condition. I have not been driving the vehicle, except for short trips around town, because I'm afraid this condition will result in a tire failure just like the Firestone tire failures of the late 90's early 2000's. I have a copy of the dealers service report if you need it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

TIRE HAS PRESENTED A BUBBLE IN THE SIDE WALL. WAS OBSERVED DURING DAILY PRE DRIVING SURVEY BY OWNER OPERATOR.

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.

For several weeks the car has felt out of balance and I had it in the shop once to be balanced. The balance felt it lasted a very short time. I took the car in today to be checked out and the passenger rear tire couldn’t hold a balance. Mechanic removed tire and the interior sound deadening foam had detached on greater than 50% of the diameter of the tire. This has been widely commented on as a common failure mode for these Hankook tires on EV9 vehicles. I wanted the remaining tires inspected but as they would hold a balance the dealer had no reason to put in the labor of removing and inspecting the foam. 285/45 R21

205/60R16 Noticed that all 4 of my tires the rubber is peeling went to tire place they said they were chunking and they should not be having 23500 miles on my 2023 Kia soul tires have been rotated every 5000 or so miles

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.

while operating my 2026 Honda Civic, I experienced a sudden and catastrophic tire blowout with absolutely no prior warning. At no point before or during the incident did my Tire Pressure Monitoring System (TPMS) alert me via the dashboard that my tire pressure was low or compromised in any way. Three critical failures occurred in this incident: 1. TPMS System Failure — My federally mandated TPMS system, required under FMVSS 138, failed to detect and alert me of dangerously low tire pressure prior to the blowout. I had zero dashboard warning at any point. 2. Tire Integrity Failure — The tire experienced a catastrophic sidewall blowout on a brand new vehicle. No road hazard, debris, or obstacle was struck prior to the failure. The structural integrity of the tire failed without cause. 3. Vehicle Safety System Communication Failure — The vehicle’s onboard diagnostics failed to detect and communicate a critical safety condition to me as the driver. On a 2026 model year vehicle, multiple redundant systems should have caught and communicated this danger, giving me the opportunity to respond and prevent the incident. These three failures created a dangerous chain of events that left me with no ability to take preventive action. The incident caused significant emotional distress. I have retained the damaged tire as physical evidence and have documented the incident with photographs. I am requesting a full investigation into whether this represents a pattern of TPMS and tire failures in the 2026 Honda Civic, and whether a safety recall is warranted. Evidence retained: Damaged tire, photographs of damage, vehicle in current condition for TPMS inspection.

Hankook Kinergy GT - 225/50R17 94V Original Equipment (OE) on 2024 Honda Accord EX/L During regular and routine service by the dealer, tires were rotated every six months. Abnormal wear was noted at 5,800 miles with original 10/32" tread depth down to 7/32" on two tires. At 17,100 miles (18 months), abnormal inside edge wear was noted by the dealer and an alignment performed. A "Caution" was noted on the Multi-Point Inspection for both rear tires at this time. We started noticing a vibration and sound seemingly coming from the right rear tire associated with tire rotational speed while on a long road trip. A Honda dealer (Fargo, ND) did a cursory inspection and declared the tires in need of replacement due to tire wear. Upon inspection at 23,976 miles (25 months), our home dealer identified tire separation on the right rear noted cords were starting to show. The service document states: "The rear tires inside treads are starting to show cords and separate. I found that the right rear tire's inside tread was worn down to the cords in spots and that the tire is starting to separate. The front and left rear tires are not as bad, but it is close to being in the same condition that the right rear tire is in. I recommend that the customer get a set of 4 new tires and after installing the tires, performing an alignment." Note: This car has never been driven on particularly rough or potholed roads.
