To Whom It May Concern, I am submitting this complaint regarding a 2012 Hyundai Elantra equipped with the 1.8L Nu engine, which is experiencing premature internal engine damage that presents a potential safety risk. 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...

I have had my car since 201. I brought it brand new. In that time, I have had to replace the tire sensors (TPMS) on my tires multiple times. They keep failing or something is wrong with the system. Even after brand new tires (and sensors) the warning fault light on the dash illuminates intermittently. Sometimes after 45 miles, it goes off. If I go on a rough road it sometimes illuminates and stays on for some time. The only fix mechanics have is to replace them every time, just for me to have the issue repeat later.
