I am sure this has been addressed before, but I could not find it. Purchased a 2017 QX30 sport and drove it home. Immediately I noticed the engine running temp between 1/2 and 3/4 mark on the gauge. When stopped and still running for a few minutes, the engine would cool down to 1/2 mark. This is opposite of any other vehicle I've owned. The next morning I checked the coolant level and it was normal. Thanks in advance for the help
