   I have not experienced a failure as of yet. But the CP4 fule pump is prone to fail. With that failure the engine is destroyed as well. So why is there no recall to get the CP4 fuel pump replaced? GM has been sued correct? A settlement of $35 million due to the failure of the CP4 fuel pump. So why is there no recall to address the issue before it happens? I have contacted GM directly and got no assistance. They just told me to fill a complaint. My Vehicle is a 2016 GMC Denali…

   Having the same issue as the recent recall on the 6.2L v8 engine failures. This has been an ongoing issue from well before the 2021 and up manufacturing dates according to many online complaints. My vehicle now needs a motor due to complete failure.This came out of nowhere with no warning very recently. It is not drivable and a new motor is not in my budget when I still owe money on the truck. GM needs to step up for the rest of these failures.
