2021 DODGE CHALLENGER Electrical System Problems

My seatbelt seemed a bit faulty when I purchased the car. It was slow to retract and at some points wouldn’t retract unless I played with the seatbelt. Three years in to owning the car it still won’t retract fully and is at the point where it won’t come out to a safe distance that allows me to wear my seatbelt. As for the electrical defaults, there are times when I am driving and the display, between my speedometer and rpm dials, turned off. So would my center display, yet my radio continued to play. There were no warning signs or signals when that would happen. It is always random.

The cars light notifications on instrument cluster panel turned on all of them at the same time while accelerating jerking the car on freeway I have video of that happening and can provide it upon request it did caused a minor accident but I settled the accident with other driver with cash with out involving insurance or police but the car is not being driven that much ever since accident it was nothing serious just a little damage to front bumper but it was really scary when it happened again on freeway thats why i recorded the problem live and can provide the video at request havent went to get the car checked out or repaired yet but definately need to it's a safety issue and dangerous one if happens at the wrong time or place I haven't received no calls from dealers or mail but will wait for further...

speedometer is messed up and not working properly what should I do?
