Coolant light continues to come on. I've had it to the shop and they say that it is a manufacturing problem. However they are not willing to fix it. I have the same problem on my Chevy high country that has the same 6.6 diesel engine in it. The mechanics all acknowledge that this is a problem for all of these model 6.6 diesel regardless of whether it is GMC or Chevy. This should definitely be a recall. The warning light continually comes up on the display saying I am low on fluid. However, when I check it it is always full. There is a high chance that if it is low I will automatically reset it thinking that the warning light is not functioning correctly. Again, the GM text knows that this is a problem throughout the fleet. Again, this should be a recall. If you have further questions you can reach me at [xxx] thank you for your time, [xxx]. information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

GMC has refused to find a fix for the heater cord defect which is one of the main reason why I purchased the vehicle. I live in Idaho. GMC should compensate owners until fixed.
