My brother in law is a tech at a different dealership and says to his knowledge they’ve never had an issue either. I actually mentioned this to that particular YouTube Technician in a forum. His response was that we must have better quality of fuel in Missouri.
If he reads this thread I’d be curious to know if Bdcardinal knows of any of these issues coming through the dealership he works in.
I agree with you. My Impala has the 3.6 DI. I have put over 50,000 miles on it. I recently did a 3,000 mile round trip. I made the same trip 3 years and about 45,000 miles ago. The overall trip MPG was virtually the same (within .3 MPG) and the power felt the same as well. (The MPG was actually higher this time than last time).
On one of the Impala forums, they have had this discussion. There are several people with 75,000 - 100,000 miles on their engines who haven't had any trouble. There are however a couple of people who highly recommend a catch can. Funny thing is, one of them sells them at a substantial price.
I'm not saying there wasn't a problem with some engines to start with, but I think for MOST the kinks have been worked out. I am so happy with mine, I will most likely be buying another GM vehicle with the same engine in the next couple of months.
