So the first time I dropped the truck off at the service center, they reinitialized one of the control modules. Well the error came back the next day. I dropped it off again today and now they say they have ordered the Vertical Sensor for the Left Front Shock and it will arrive by Tuesday. But I'm still not convinced that's the issue based on someone's post over here. I couldn't find that thread. So should I start reading up on the lemon law?..
