Diesel Engine Problems of GMC Sierra

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 308-940-1071 thank you for your time, wayne williams.
