First time poster, long time GMC customer. 2015 Yukon Denali XL 63,000 miles 4wd. Got in the vehicle to take my family out to dinner on July 10th, 2017. Less than 1/2 a mile after driving I noticed the idle wasn't right and felt a slight shudder. I slowed down and looked for a place to pull over. About 10 seconds later the truck stopped running and I pulled over to the side of the road. There was no warning lights on and all gauges showed the correct temps and readings. I tried to start the truck and it turned over but didn't start. After that initial attempt the starter would not turn the engine over. My first thought maybe the battery was dead and that caused the truck to stop running. Hooked up jumpers and no difference. Had the vehicle towed to our local dealer Watson Chevrolet in Tucson. After the dealer removed the pulleys and tried to turn the block by hand they called to inform me that my Yukon had overheated and seized the block. I was shocked to say the least! Apparently there has been a light leak in the radiator that was not noticed by me or their service department. The dealer is taking the stance that since the radiator was not covered by power train the repairs to the motor will not be covered. My stance is that the vehicle never had a low coolant warning or even showed a change in the engine temp that was out of line. The temperature gauge read normal the entire time and no warning lights or messages ever came on. 5 weeks prior I had the truck into the same dealer trying to resolve a hard shift problem. They replaced the valve body on the transmission and the temperature sensor for the transmission. Apparently the transmission sensor was not displaying the correct temp and needed to be replaced. The dealer wants me to authorize a tear down to see what the cause was. It is apparent that the radiator leak was the cause of the overheating but I had no indication that is was low on fluid or that it was overheating. The dealer can't tell me if they find that the warning system or gauges were not functioning properly that the warranty will cover the rebuild of the motor. I am looking for advice on how to proceed.

2019 3500HD Duramax Dually- The passenger seat belt warning light and chime to not work. Have been informed by dealer that GM discontinued that feature in this brand new truck. Is this true? If it is how does the airbag system know there is a passenger as I believer that was all integrated.

BIGRED13 posted a topic in 2014-2018 Silverado & Sierra Troubleshootinghey yall, been a while. I have a message that's been coming up in my cluster display saying service trailer brakes... uh no trailer on atm . so I pulled the trailer plug out, inspected for corroision, none found, check for shorts in the 7 pin connector itself no problems, I have continuity through all the 7 pins and the associated 4 pins below, only fault in the trailer brake module was for voltage to low from by battery being dead this morning. im thinking the battery died because of the trailer brake faults. it usually after it rains and then the sun comes out, but this morning was the first time my battery died, anyone else have a problem like this. anyone have a good wiring diagram for modules to the plug on the bumper?
Battery Light and Warning
RCM826 posted a question in Ask the GM TechnicianPeriodically my 05 Silverado flashes a red battery warning light and a "Service Charging System" warning displays. The voltage then begins to fluctuate maybe 2-3 volts over and under 14v. Lights dim and brighten. Then warnings shut off and all is back to normal. This happens at least once a day or so for about a year. Hasn't gotten worse....any idea what problem is?
