2018 Yukon Denali, 105K miles
Just had both rear shocks and compressor replaced by our fleet mechanic. At their recommendation, we went with aftermarket shocks (almost $1K price difference!)
It has been about 2 weeks since they were replaced. Problem didn't start until a couple of days after I got the truck back, and on the way to work in the morning, I got the "Service Suspension System" error. Pulled the codes but did not clear them because I was planning to take it back to the mechanic. The codes cleared themselves on the next start, and after talking to the shop, we decided I would take it there next time I got the error. Well, the codes never came back until 5 days ago, and now it occurs practically every morning, but is gone upon the next restart. I plan on taking it there and dropping it off one night so they can reproduce the error, but I am wondering if this is something that has been seen before.
(I also found out that the truck is now limited to 85 MPH when the error is set...
