2024 Harley-Davidson Fxbbs

I have 2 problems that I believe are situations that could be considered safety problems, I purchased my motorcycle in November of 2024, new, from the Harley Davidson dealership in Orlando FL. and since that time I have had the bike in the shop 5 times. The problems are that the rear brakes are not working correctly it takes a tremendous amount of pressure before they will begin to slow the bike down, I was told that this is normal and that the brakes should only be 30% effective, I have that in writing from the dealership, the second problem is that the engine idle is very erratic and the bike has stalled several times while sitting at a red light, and after sitting at a red light or a stop sign for any amount of time the throttle response is very sluggish. I have checked many forums online and it appears that these are very common problems and nothing is being done about the problems. The solution I am being told is to purchase different brake pads, rotors and brake levers to make them work properly. The engine problem can be fixed by purchasing aftermarket tuning kits to change the ECM mapping. I don't think that the safety issues should be overlooked and that a customer should expect that a new Harley Davidson should handle, brake and run correctly.
