GM knew about this issue LONG AGO. Kudos to GM for extending the warranty, but I can’t imagine GM getting out of this without lawsuits. GM kept producing engines that they knew were failing for years without stop sales.

The good: You get a new L87 engine if they scan and detect certain codes in your truck.
The bad: You’ll have to watch the video 🙂
