2015 Mercedes-Benz E-Class 4dr Sedan

302-horsepower 3.5L V6 7-speed shiftable automatic RWD

10100 mi Brake sensor detached from brake mechanism. 
10000 mi AC not cooling car. Dealer found AC hose leaking. Replaced, recharged. Still not cooling well. AC randomly goes to FULL HEAT in the middle of a Florida summer. Been to the shop THREE times now, still a problem hard drive squeals periodically Self-driving system and ECO start/stop were fighting with each other at red lights, causing the car to lurch forward and turn off brake lights. Not sure what the dealer did, but they actually managed to fix this. 
18000 mi Not cooling sufficiently (still) AC goes to full heat automatically Hard drive squeaks -- replaced entire AV/NAV headend 
25600 mi Stereo system rebooted / lost settings overnight Bluetooth audio keeps cutting out. Problem started after a software update. Now they've been replacing parts, but not fixed. Bluetooth worked fine until software update was done to car 360 Degree Cameras periodically won't come on. Replaced camera module 2x, replaced car stereo 
47000 mi AC goes to full heat by itself...even when full cool is selected All 3 batteries (Aux/Cabin, Transmission, Starter) replaced to address random electrical glitches. Ultimately, the car's power supply is unstable. If we "run" the car connected to mains power off a stable power source, everything in the car works normally. When the batteries in the car are replaced, all of the systems will be stable for awhile. Once the batteries start to age, the electrical gremlins start up again. This car has 3 batteries: 1) Starter/Main, 2) Aux, 3) Transmission. The Starter battery is your traditional setup. Once the engine's on, it starts charging the Aux battery. Once Aux is up to voltage, it switches most of the loads over to the Aux battery. The Aux battery is what keeps everything going during the ECO Start/Stop functions and also isolates the electronics from the wild voltage swings when the engine restarts. So they assumed... If there's any ripples on the Aux bus, everything goes to pot. The design might have worked, but they're using far too small of an auxiliary battery (probably for weight savings), so the battery's taking a beating and the systems never accounted for the aux bus being unstable. They also kind of forgot about voltage drop vs. wire resistance. Audio keeps cutting out. Started when the radio was "updated" due to problems with the 360 cameras. Random electrical glitches in the car.
