Fault to 95C

DTC P0300 is a random missfire code, letting you know that multiple cylinders are missfiring. It will shut the engine off because misfires can be damaging. Engines run more or less efficiently based on engine temperature, so the fact that it is missfiring at a certain temperature does not surprise me. As for a diagnosis, this could be bad gas, or any other number of things. It really does need a professional scan (not a code reader) to check operating conditions at 95C and find what is out of parameters. As a 2016 model, your warranty will should cover this with no problems.
