Brake Master Cylinder problems of the 2015 Hyundai Genesis

There are multiple problem points with this vehicle that become apparent far earlier than they should including but not limited to 1: starter motor complete failure at 70k miles (affects every single 3. 8 2015-2017 Genesis sedan) 2: sunroof front panel seal degradation 3: shuddering driveshaft early into new ownership (also afflicts most of these vehicles) 4: brake booster and master cylinder sudden complete failure 5: oil pressure sensor improper calibration all of these issues have been checked by multiple service centers at Hyundai/genesis dealers, all of them confirming reluctantly that these issues affect all Genesis models similar to mine. The braking issue is the worst, happens suddenly and at a random point in time, and costs thousands to fix. The starter motor failure is very common, and every dealer kept forcing me to replace meaningless parts until the car would no longer start and then they admitted it needed a new starter. The front panel between the sunroof and the windshield has rapidly degrading rubber seals, which will loudly shake and move around while driving. The driveshaft will shudder when the vehicle is cold and it’s sub 80° outside, even if the engine has warmed to operating temp. The oil pressure sensor rapidly breaks just months after the car is brand new, with it on average reading a much lower oil pressure than is actually being applied. All of these issues have been replicated, and only the faulty oil pressure sensor had a warning light, no light for the faulty brakes, starter, or driveshaft issues. The more I research into Genesis, the more I realize that these issues happen just a couple thousand miles after new, and affect every single Genesis model similar to mine.
