I think it is time for Mercedes to step up to the plate and take responsibility for these harnesses! Consumables??? What else are we going to find out is a consumable? How soon should I expect to replace my airbag and be sure it will still work? Where is the schedule in my manual for changing my wire harness? Had someone said something before I bought the car about changing the harness every 60,000-70,000 miles I might have passed over it. And guess what else... Between my dad and 2 brothers, we own 13 mercedes benz, (enough to start our own mercedes club) guess how many need harness replaced? 1 - mine and all the others are older and all run well and have never had a harness replacement! I wonder what the "consumable" schedule for those cars is! Way to go Mercedes!
