Radiator Problems of Cadillac CTS

I bought this car for my son that go to college at san jose state university, his been using this car since 2015 till 2019. Recenty about a month ago his complaining the car has been overheating for no reasons, he says that the gauge goes all the way up everytime he drive it but its ok if the car engine is running but in park mode. We ended up got the car towed to merced. Since July of 2019, the car is the garage and never drive. We only start the car mostly to warp up the engine but not drive. We have a friend mechanic look at it and can't point out the right problem, a lot of assumption possible the thermostat, or radiator, water pump, or the fan, etc.

(1) normal driving (2) rear differential leak and whine; coolant leak from the radiator (3) going to the dealer tomorrow.

Rear differential of my 2004 Cadillac Ctsv is too weak. It clunks, and produces excessive wheel-hop thus not allowing the power to transfer. The whole rear end of the car from the bushings to the rear cradle to the half shafts are too weak for the car. Over 1000's of Cts-v's of the under approx. 4,000 produced from 2004-2005 have had major issues. Service centers claim everything is normal. My car is continually in the shop. Gm refuses to pay for these item and I have a 6yr 100k warranty. Service centers are not equipped to deal with this car, and gm failed to engineer it properly. In addition all of my interior parts rattle when I step on it, and some continue to rattle during daily driving. The paint quality of the exterior is the worst I have to see yet. There are weird blotches all over the place and are obviously due to poor paint application at the factory. I have owned the car for 3 months and so far have had to replace the radiator, the whole nav unit, the rear differential. And already, the nav unit is beginning to show the same indications of why it got replaced in the first place, and the rear differential is starting to make noises again. Also, the dual mass flywheel produces lots of noise. I have had it up to here with this vehicle.

2003 Cadillac Cts, no sevice lights on, when stopped at light, smoke coming from under the hood, then smoke inside of the car. Turned off engine and assistance opened the hood, flame under hood and smoke from fire near battery. Was told that pvc valve burst under pressure from cold outside temperatures, caused oil to spray over engine and under hood and because engine was hot from use, caused it to ignite. Also told that this was the 3-4th car reported last week to one dealership with same problem. Not sure what repairs were done, car is repaired today.
