Hyundai Equus Problems by year

high-velocity metallic shrapnel. However, today, Saturday, July 11, 2026, the servicing franchise dealership, Patrick Hyundai, issued an immediate verbal denial of all goodwill repair or safety inspection coverage. This premature weekend denial represents a blatant, bad-faith attempt by a localized franchise to circumvent an active manufacturer safety audit. By issuing a verbal denial while corporate offices are closed, the dealership is attempting to apply high pressure to force me to immediately tow this severely compromised, non-driveable vehicle off their property. This action is designed solely to force the removal and destruction of critical, un-tampered physical fluid evidence before a qualified Federal Safety Engineer or a Hyundai Field Product Engineer can mandate a teardown or structural inspection. The manufacturer's franchise is actively evading its product liability and safety screening protocols for an integrated, multi-system thermal failure. I am requesting that federal safety auditors expedite an intervention, freeze any attempt to eject the vehicle from the facility, and order a formal manufacturer field safety audit. Case number 11749120

approximately 18,000 miles of operation, this restriction completely choked the transmission fluid pressure loop. The extreme thermal stress and back-pressure caused the internal walls of the transmission cooler to suffer a catastrophic structural rupture. This caused the transmission to suddenly overheat and fail while driving, creating an immediate highway safety risk and a total loss of vehicle control. Furthermore, the internal rupture of the cooler walls has caused direct fluid cross-contamination ('SMOD'), forcing transmission fluid and metallic shrapnel directly into the engine's main radiator and cooling passages. This metal shrapnel is currently circulating through the engine's cooling network, creating a severe secondary hazard of catastrophic engine seizure and thermal runaway while traveling at highway speeds. The manufacturer has been notified but has formally refused in writing to dispatch a field engineer or authorize a safety inspection of this cross-contaminated powertrain network.

from manufacturing since 2010, which can cause bearing failure and engine seizure. My Tucson's failure matches the same pattern described in Hyundai's Theta II engine recall and warranty extension campaigns. This sudden failure created an extremely dangerous situation at highway speed and possibility of injury while being stranded on an open road. Many owners, myself included, were never properly notified of the risks. I am filing this report because this incident represents a serious safety defect and potential recurrence among similar vehicles that may not yet be covered by recall. I respectfully request that the National Highway Traffic Safety Administration investigate this issue and ensure Hyundai expands its recall and warranty coverage to include affected 2014 Hyundai Tucson Limited vehicles exhibiting this defect that was well-known to the Hyundai Corporation. Date of Incident: October 23,2025 in Houston Texas. Vehicle towed to Hyundai dealer which diagnosed Engine Seized and currently awaiting Warranty Extension Approval (TXXC/TXXI)
