My concern is brake and rotors. I replaced brakes a few months after purchasing my vehicle in 2020. My dealership was not helpful about experience. I asked why brakes were not inspected B4 purchase and after several calls repairs were done. It's been 1 year and vehicle has not been driven much due to covid. Now having same problems with shaking again.. I feel brakes are a on going problem with this model and I need answers. I have read many complaints on line about this problem with brakes rotors on Cla250 Mercedes Benz.please help

Car taken to Mercedes Benz service department on 1/3/2018 for collision assist system failure on 12/30/2017 causing car to lose power, collision assist system warning alert, auto braking (all at highway speed while entering highway from on-ramp). Only solution was to limp to side of freeway and turn off car, then restart. All warnings cleared, car returned to normal state. Able to drive. Occurred twice before (12/22/2017 and 12/23/2017). After receiving car back from Mercedes Benz service department, reported issue was ca sensor was loose in its seat after visual inspection. Reported to have replaced sensor and re-seated, initial startup on ca module including update and calibration, test drive of 9 miles without incident, reported as "everything functioning at this time". vehicle retrieved from mb on 1/4/2018. On 1/6/2018, issue occurred again after making right hand turn on surface road and accelerating to approximately 25 mph (45 mph zone). Same situation: Loss of power, auto dampening, collision assist warning and chimes. Taking vehicle back to mb service department. This is a known issue among 2015 mb Cla250S, as reported on mbworld blog site - https://mbworld.org/forums/C-class-W205/584375-collision-prevention-assist-plus-inoperative-error.html.

Immediately after entering a freeway from an on-ramp at approximately 60mph, warning chimes for collision indicator deactivated came on, auto-dampening of engine speed occurred, and auto-braking occurred. No vehicles were directly in front of vehicle, nor near enough to side or rear cause proximity sensors to activate. The only remedy for this was to limp to the side of the road (in rush hour traffic), turn off car, and then turn back on. All indicators and warnings were cleared upon restarting vehicle. This is the second time this has happened within 12-months.
