Hi everyone, new owner of a used g37x that has about 100,000 miles. Hoping to add another 50k miles on the odometer. One thing that stood out to me was the heat coming from under the car soon I exited the vehicle after a 40min drive, but I am used to driving a truck that sits much higher and gets more airflow underneath. Is this something I should be concerned about and what else should I expect out of this car from now until then?

 

HI, welcome to the forum and congrats on your new purchase. Post up some pictures when you have a chance so we can all admire it too! I wouldn't be concnered about the heat coming off the car these cars run a bit hot in general, but if you are really worried it wouldn't hurt to do a coolant drain and fill and other fluid service given the mileage. adding another 50 k should be a breeze

 

It's probably heat from the catalytic converter/exhaust, don't worry about it.
