Between 30K and 36K miles, the vehicle underwent 3 violent highway deceleration episodes.  During these events, the engine began shaking, escalating to violent shaking; with deceleration and coming to a stop, it would shake, then sputter as if it would die.  Coming to a complete stop, a total stall was prevented only by the ECM forcing a limp mode lock at 1200 RPMs.  When Auto Hold was engaged at this point and my foot was removed from the brake pedal, the mechanical surge caused the vehicle to unexpectedly lurch forward, fighting against and nearly overriding the factory Auto Hold braking safety feature before finally holding.  Luckily, no pedestrian was walking in front of my car when this occurred.  No check engine light (CEL) or dashboard warning ever illuminated.  This safety compromise is directly tied to an ineffective or adjacent remedy involving Service Campaign 9B1 (Opcode 40D219R0) and Safety Recall 286.  Under this Opcode, a factory software flash deleted the standard OBD-II trouble code P0451and substituted it with a manufacturer-specific shadow code P14EE00.  This software manipulation suppressed universal emission/pressure sensor faults, masking a volatile physical defect within the high pressure fuel delivery and ignition systems.  Dealer diagnostics on a running, compromised engine flagged an improper fuel injector pulse and subsequently a failing Cylinder 3 ignition coil.  All four injectors were replaced but only one coil, leaving 3 non-updated , factory defective coils in the engine.  The vehicle remains an ongoing highway stalling and brake-override hazard due to an incomplete field remedy of a recall-adjacent system.  I've filed a Hyundai Complaint with assigned case number 43394228 regarding Safety Recall 286.  (Two episodes of the attempted Auto Hold override occurred - first 09/09/2026 and second 09/29/2026.)","products":[{"type":"Vehicle","productYear":"2020","productMake":"HYUNDAI","productModel":"SONATA","manufacturer":"Hyundai Motor America"}]}]}
