2024 Kia EV9: tire blowout or tread separation

Filed Oct 17, 2026 · Body, Driver assistance · TX

On my 2024 Kia EV9 GT-Line, the front illuminated digital pattern acrylic/plastic grill panel suffered a catastrophic structural failure, resulting in a complete blowout and puncture hole under normal driving conditions. The panel fractured and shattered completely while driving on standard paved roads, with zero history of front-end collisions, low-speed impacts, or road debris strikes. This indicates a severe material strength, thermal stress, or structural design defect where the acrylic housing cannot withstand normal operational driving forces. Given its placement over critical forward-facing ADAS sensors, cameras, and electrical lighting elements, this open hole and structural failure presents a severe safety, sensor compromise, and moisture/debris intrusion hazard. I am submitting this report to document the defect and wish to cross-reference existing complaint number 11589157, as multiple owners are experiencing identical structural failures of the illuminated grill panel under normal driving conditions. Requesting a federal investigation into material durability and a manufacturer-backed recall.

What component or system failed or malfunctioned, and is it available for inspection upon request? Two components failed simultaneously: (1) the rear passenger side tire experienced a catastrophic blowout while traveling at 65 MPH on the highway, and (2) the Tire Pressure Monitoring System (TPMS) failed to detect or warn of any tire pressure abnormality before or after the blowout. Following the blowout, the vehicle’s diagnostics screen displayed “All Systems OK” while the instrument cluster simultaneously showed a “Low Tire Pressure” warning — indicating a TPMS malfunction. The original blown tire has been retained and is available for inspection upon request. All four tires have since been replaced. How was your safety or the safety of others put at risk? A tire blowout at 65 MPH on a highway created an immediate risk, I briefly lost control of the vehicle as it became wobbly and unstable to steer, we were at at risk of collision, or rollover. Two minor children were passengers in the vehicle at the time. The simultaneous TPMS failure provided no advance warning, eliminating any opportunity to safely reduce speed or pull over before the blowout occurred. The vehicle had been in my possession for approximately two-three hours at the time of the incident. Has the problem been reproduced or confirmed by a dealer or independent service center? UNKNOWN Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? UNKNOWN Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning lamps, messages, or symptoms appeared prior to the tire blowout. The TPMS provided zero advance warning. After the blowout had already occurred and the vehicle was stopped on the roadside, the instrument cluster displayed a “Low Tire Pressure” warning. However, simultaneously, the Vehicle Diagnostics screen displayed “All Systems OK” with a green check-mark.

Purchased new all four tires (P 285 / 45 R 21 113V XL) in Dec, 2025 after confirming fits my vehicle. Warranty 60,000 miles. About 4 months later and about 1,800 miles of use, both rear tires have lost most of their tread and steel belts are showing per auto dealer. Front tires have also los quite a bit of tread. Vehicle had 4 wheel alignment before these tires were installed. Dealer & vehicle manufacturer representative confirmed no issue with vehicle. Also noted on 4/29/2026 that tire manufacturer web site states that these tires are no longer available for my vehicle. This is a significant safety hazard in its present state and worse yet subject to sudden tire failure.

2024 Kia EV9 has destroyed two complete tire sets in 4 months (October 2025, January 2026) despite two professional alignments (May 2025, October 2025). Dealer service manager admitted on recorded call (1/7/26) seeing multiple EV9s "under 18,000 miles" destroy tires, confirming fleet-wide pattern. Multiple owner forums report the exact same issue. MY CASE: - [XXX] (11,860 mi): Steering misalignment, independent shop (Town Fair Tire) confirmed alignment issue - June 2025 - Vehicle inspected and tires rotated by authorized Kia dealership - Berlin City in Vermont - October 2025 (22,736 mi): Left rear BLOWOUT while driving. ALL FOUR OEM tires (113 load rating - "correct" per Kia) worn to bare threads. Tires had ~18,000 miles on them. October 2025: Snow tires were installed in October 2025, with 10/32" tread (were driven ~4,000 miles the previous winter). Dealer performed alignment, no before/after documentation provided [XXX] (25,486 mi): Same winter tires that drove 4,000 mi perfectly first winter destroyed in 2,700 mi second winter DEFINITIVE PROOF - Multi-Point Inspection (1/5/26): On 1/5/2026: Rear Left: 1/32" tread (destroyed in 2,700 miles from Oct. '25 to Jan. '26) Rear Right: 1/32" tread (destroyed in 2,700 miles from Oct. '25 to Jan. '26) Front Left: 10/32" tread Front Right: 10/32" tread Rear-only catastrophic wear on AWD vehicle is definitive proof of rear suspension or alignment defect. If load rating or overloading were the cause, all four tires would wear equally. SAFETY HAZARDS: Left rear tire BLOWOUT October 2025 while driving at 35 mph. Service Manager Pat (1/7/26): "Under 18,000 miles I've seen" other EV9s destroy tires - CONFIRMS FLEET-WIDE PATTERN Service Manager: "I can't tell you why the alignment is out" - CANNOT DIAGNOSE ROOT CAUSE Service Advisor John (1/6/26): "There's got to be an elephant in the room somewhere" - ADMITS UNDIAGNOSED DEFECT EXISTS Service Advisor: "I wouldn't feel safe putting my guys in it" INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),
