   I have had 2 catalytic converters the original and a 2nd one. Now I need a 3rd due to excessive oil consumption. Corporate did a good will for a combustion cleaning and that did nothing. The dealership checked my oil and said there was excessive oil consumption and submitted for an engine replacement and it was rejected. Absolutely ridiculous.

   On March 21st, while driving my Hyundai vehicle, I noticed the vehicle began making a ticking sound. After stopping the vehicle, it slowly began catching on fire.

   The vehicle is experiencing excessive oil consumption and increasingly severe engine performance symptoms. The oil level drops rapidly between changes, but the loss is not due to external leaks. The engine burns oil internally, causing residue buildup and damage to other components — specifically the intake manifold and catalytic converter, which the dealer has now recommended replacing. These issues align with the symptoms addressed in Hyundai Campaign 966 (Engine…
