One problem related to diesel engine has been reported for the 2017 GMC Sierra. The most recently reported issues are listed below.
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.
