A recent high school graduate says what started as a routine oil change turned into a nearly two-year ordeal involving a blown engine, repeated breakdowns, and an upcoming court date.

Casandra (@casandraa.oo) shared the timeline of what she says happened after taking her graduation-gift Porsche Cayenne in for an oil change at what she described as a large instant oil change chain in Tennessee, likely Valvoline.

She says she graduated from high school in May 2024 and received the SUV from her parents a few months later, in August. In December, she took it in for an oil change.

According to Casandra, problems began almost immediately. She says that after driving home, her dashboard displayed an “oil pressure low” warning. When she contacted the oil change shop, she says employees told her they didn’t know how to reset the warning.

The next day, she says the Porsche barely started and made a rattling noise. After she and her brother contacted the shop again, she says employees determined the engine had failed.
