There is a safety recall on GMâs 6.2L V8 L87 engine model years 2021-2024. My vehicle is a 2020 Suburban with a 6.2L V8 L87 engine. My engine recently experienced the same failure as cited in the recall, but because it is outside the 2021-2024 window it is not covered by this recall. I ask that the recall be expanded to additional years where these engines are experiencing the same failure as is covered by the current recall.
