Vehicle details: Year/Make/Model: 2012 Hyundai Elantra  Mileage: Approximately 134,500 miles Issue description: The engine produces a persistent ticking/knocking noise, most pronounced at cold start but now continuing even after the engine has warmed. A Hyundai dealership diagnosed the vehicle with piston slap and confirmed significant scarring on the cylinder walls, stating that the only repair is full engine replacement. Despite the presence of internal engine damage, no warning lights are illuminated. I am concerned this condition could lead to sudden engine seizure or loss of power while driving, creating a safety hazard. Additional observations include: Excessive crankcase blow-by observed when removing the oil fill cap while the engine is running Strong exhaust fumes at cold start Noise most noticeable at idle and low RPM Regular oil changes using manufacturer-recommended oil viscosity The dealership advised the condition was not repairable short of engine replacement and did not submit the concern for Hyundai corporate technical review (Techline), despite the known history of engine defects in Hyundai Nu engines. I am filing this complaint to document a pattern of premature internal engine wear that may not be adequately addressed through recalls or warranty programs, and which could result in sudden engine failure. Thank you for your attention to this matter.","products":[{"type":"Vehicle","productYear":"2012","productMake":"HYUNDAI","productModel":"ELANTRA","manufacturer":"Hyundai Motor America"}]}]}
