Hi I’m a new member. 2018 eco diesel Laramie 4x4. 27k. Had for 3 months 4K miles couldn’t be happier with truck. Only issue was with sound system . One day all sound stated to come out of front driver speaker only. Settings in that area were ”frozen”. Not able to select sourrond sound or move icon around cab.. 3 days later It had a spontaneous recovery. Considering GDE tune in future but it runs so well now I don’t want to cause any problems. I have a fair amount of diesel DIY experience with ‘80s Mercedes diesels. I’m hoping that 2018 and forward doesn’t have 2014-2017 problems. great to be here
