It's actually a reference to a major US-based robocall scam; see my other comment.

From Knowyourmeme:

“According to an NPR interview from April 2021, phone scams about “your car’s extended warranty” started in the United States in 2007. A company called US Fidelis started a robocall campaign in 2007 that was legal but deceptive. Within the fine print of the extended warranty contract they offered was a clause that exempted US Fidelis from paying for a car’s repair in the shop. US Fidelis preyed on people who answered the robocall and signed the contract without reading all of the fine print.”
