In the course of visiting the dealership, I've started considering the possibility of an upgrade. Of course, what I wouldn't want is to discover that the new vehicle has the same issue, and in the worst case, it is potentially only discovered after the warranty expires...
Is there any way to determine for any particular vehicle whether it was built with the newer engine type with the modified relief design, or the older style engine? Perhaps based on the VIN# of the vehicle in question?
