It amazes me to keep reading about the problems posted regarding the LMM and limp mode. I understand it is a new design of the truck but other than the DPF is it not a proven drivetrain? Is it just the luck of the draw that I haven't experienced this yet? I understand the ratio of problems compared to trucks on the road is probably miniscule but I seem to find myself waiting for this dreaded experience. I have no perf. mods with 14K miles on mine, with over 2500 pulling a 8000lb trailer, I've got on her hard, I've remote started and idled it, drove through snow storms and a couple of weeks of -15 to -25C Canadian weather... so far only 2 leaky tranny lines have been replaced. Not bad in my estimate for a new design. Yet still I get nervous.... it's my first diesel so hopefully this passes. Am I being paranoid or does it make sense to buy a code reader/clearer? Is there anything else you can do to prepare?
