Sucks they are not offering it however them holding production must mean they are putting a ton of focus on the 17 which is really good news!
I know there have been some people with issues, but there are also many like me who have had no or only minor issues. I have just about 125K miles on my diesel and still a reliable daily driver.If GM cant solve all of the problems with the current 2.0 diesel( Sensors, Fuel System issues ) then they need to wait on this. It would be a disaster to introduce another diesel test platform.
I do drive a lot of highway, but i also spend considerable time idling in stop and go traffic. Maybe the highway "cleans out" whatever builds up in the traffic.The folks who are having problems with their CTDs appear to be mostly city drivers. I wonder if the delay is to figure out how to resolve this in the next diesel release.
