   The vehicle has an unpredictable and random tendency to hesitate when the gas is pressed. This has been happening at some level since the vehicle was new.

Now that it is out of warranty, the issue is getting worse. It is to the point that I believe it is unsafe for anyone but me to drive it. I have to make sure that when I turn onto a…

We drove it to a mechanic shop, and they said the code stated camshaft and other component issues, but the engine ended up failing completely and was rebuilt. We initially checked for recalls and our VIN did not show any; however, we recently became aware that our engine (6.2L) might be part of the ongoing current problems associated with a recall.
