ENGINE

My car's engine is burning oil. I have maintained service of oil changes and fluids, etc. since I purchased my car. It is not that old in my opinion.

POWER TRAIN, ENGINE, ELECTRICAL SYSTEM

am writing regarding 43099808 Number with Hyundai My 2019 Sonata hybird se in limp mode with an active flashing P1326 knock sensor code. The dealership is using an automated system denial to try and charge me $2,110 for an EGR valve and air filter.I am officially challenging this diagnostic path. Mathematically and mechanically, an EGR valve or MAF sensor cannot generate the structural rod-bearing acoustic frequency required to trip a manufacturer-specific P1326 engine protection code.Furthermore, the tracy Hyundai certified my vehicle's warranty compliance and replaced my knock sensors under the KSDS campaign only two weeks ago. The fact that the P1326 code flashed again 14 days later proves the new sensor is successfully detecting an internal structural engine failure. I am requesting an immediate manual override and a field review by the District Parts and Service Manager (DPSM) for a full engine replacement under the terms of the lifetime class-action warranty.

FUEL/PROPULSION SYSTEM

The low-pressure fuel pump module assembly, located directly beneath the rear passenger seat cushion, experienced a plastic housing failure. A stress fracture on the upper plastic fuel outlet nipple caused raw liquid gasoline to actively weep and pool on top of the module inside the passenger cabin. This component is retained and available for inspection upon request. RISK TO SAFETY: Raw liquid gasoline pooling inside the interior passenger compartment creates an severe, immediate fire and explosion hazard. Additionally, vehicle occupants were exposed to toxic fuel vapors while driving. INSPECTION & DEALER CONFIRMATION: An authorized Hyundai dealership inspected the vehicle and confirmed raw fuel leaking at the top of the fuel pump module assembly. This exact module had previously been removed and disassembled during a 2024 manufacturer recall service to replace the internal fuel filter and tank seal. Stress applied to the plastic fittings during that recall service appears to have caused the plastic top-hat to fracture over time under line pressure. Hyundai Corporate was notified of the safety hazard and prior recall history, but refused assistance. WARNING SYMPTOMS: The failure began with a strong, persistent fuel odor inside the vehicle cabin. No dashboard warning lights, check engine lights, or diagnostic trouble codes (DTCs) triggered prior to or during the failure. SUMMARY: A stress-fractured plastic fuel pump housing allowed raw fuel to pool in the passenger cabin following a prior manufacturer recall repair involving the disassembly of the same component.

ENGINE

The oil is low, went to get looked at by another mechanic besides Dealer cause they want to hit you over the head with prices. Was told car burning oil. Took to dealer for Oil Consumption Test. Had to pay for oil change. Came back a little before 1,000 miles and car failed. They charging me 900.00 for next step because I can’t find ALL the oil changes. I just don’t get it, if this is a known issue with this model engine why do I have to pay.
