1965 Posted February 24, 2015 Share Posted February 24, 2015 I think main thing is to have a dealer or mechanic that HAS knowledge on these newer trucks Quote Link to comment https://www.bigmacktrucks.com/topic/39049-thoughts-on-08-and-09-pinnacle/#findComment-280471 Share on other sites More sharing options...
wheeler73 Posted February 25, 2015 Share Posted February 25, 2015 They are a good solid truck. I would like to see the maintenance records and have a good shop or dealer look the truck over. As we know it is a used truck and can't guarantee it will not have any unseen issues.

Mackdaddy2030 Posted March 19, 2015 Share Posted March 19, 2015 I was told to stay away from '08-'10. Heard the just DPF trucks had lots of problems and to go newer with ones that have urea. I know the one construction company in my are has a bunch of '08-'09 Granites that they were trying to fit rid of, but no one wanted to take them in on trade.

bbigrig Posted March 19, 2015 Share Posted March 19, 2015 I have a few 08's they are doing ok. a few sensors now and then but nothing abnormal for a post '07 truck no matter what the make.There is a big difference in the amount of issues you may have that is relative to the work you are doing with the truck.Highway operation seems to have the least amount of issues as in this application, the operational temperatures needed for re-gens to keep the DPF system cycling come easy hauling steadily along the highway.If you get into Granites and MRU's and LEU's thats were I have seen the issues go through the roof. Excessive idling, short trips, stop and go travel. The engines cant maintain high engine temps long enough to keep the designed DPF system operating properly. The MRU/LEU's is a different beast all together and has its own issues.As long as the engine is running as it is intended ( no issues that will cause over fueling or excessive soot in exhaust) our CXU's run fine. have a leaking/cracked/freted injector tip fro example which seems to be more common as they get older and you get all kinds of issues with the DPF set up. Ours are around or over 1,000,000kms and are still running down the highway very well. No DEF pump or module issues like our post 2010 trucks.
