2020turbomax3.0chevyxlt4x4

Update: Service department found no codes, found nothing wrong. They did see the temperature fluctuate a lot as did I. Luckily an engineer from GM came in to take a look and check if any updates were missing and there was one but it didn’t change the fluctuation. The truck is so new to them you all know more about it. Even their mechanics, even their engineers..... let that soak in haha guess I’ll be calling Detroit motors about the 3.0 engine temp and I’ll update you with any new information.

Thank you all for your replies!!!

On a hot day through the mountains during week two of owning it. (Had 80 miles when I bought it) the engine temperature went to 236. Now I’m no professional mechanic but that seems a bit too hot. Especially for a new vehicle. I understand the it requires to get hot for efficiency and also to clear out diesel exhaust. But for a truck to be close to distortion levels this early into ownership... what do you think?

Just purchased a 2020 Chevy duramax 3.0 turbo diesel XLT 4x4 towing package. My engine temperature has been going above 210 on a regular basis and the engine temp fluctuates between 210-235. Has anyone had this? I turned it in for service because it seems very odd. I’m not towing anything or carrying any abnormal amount of weight (just carpentry tools).
