This weekend someone slammed my passenger door probably to hard in my opinion. Not sure if this is the cause of the problem but the issue did start soon after. The Window and mirror lost power first intermittently, now completely. I checked the fuse and also didn’t see anything obvious as far as wires being loose or broken from the harness. Any suggestions or recommendations for a fix would be greatly appreciated.

General Motors has announced that NHTSA is mandating a safety recall for the following vehicles:
2014-2018 Chevrolet Silverado and GMC Sierra Pickups (1500 / 2500 / 3500) 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles 2015-2017 Cadillac Escalade
NHTSA reports that the amount of vacuum created by the vacuum pump may decrease over time. The group says that as the vacuum level drops, the brake assist decreases, and that this increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash. This new recall covers 3.4 million vehicles.
The Problem: The brake pump uses engine oil to lubricate itself. If the pump becomes clogged with engine oil sludge the units ability to create vaccum is diminished over time. As a result, braking force and ability also drops. The issue is usually accompanied by a "Service Brake Assist" warning message in the dash.
The Fix: GM will reprogram the computer that controls the secondary brake assist pump. The secondary pump will now activate at lower speeds and different situations quicker to compensate for any lost output from the main pump. Since the pumps are not failing, GM has decided not to replace them.
GM's number for this recall is N192268490. In compliance with federal law, GM will notify owners, typically by snail mail. GM says that its dealers will reprogram the Electronic Brake Control Module. However, GM has not yet provided a notification schedule. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782.
If you own one of these vehicles and wish to check to see if your vehicle is included (or not) you can do so at this link immediately.
As with every safety recall, customers will not be charged by GM for the needed repairs or modifications.
NHTSA's public information on this issue indicates that many accidents have been reported to NHTSA including some with injuries. This recall is the result of a NHTSA investigation that lasted nearly a year. In its investigation report, NHTSA noted the following details about the problem:

My 2014 Silverado has developed an unbelievable rattle in the cab. I would swear up and down it is in the center of pillar A on the passenger side.
Has anyone else had this problem?
I have it took apart right now, and I cannot find where it is coming from. Its going to drive me crazy.
Any help would be very appreciated.

I have a 2014 Silverado LTZ (very high milage - 219,000) Runs great and still has some power left under the hood. For the most part, it is in great shape. It have a strange noise when acceleration or getting up to about 3 or 4 thousand RPM. It only does it under load, so it is hard to find where the noise is coming from. In the attached video, it takes place at 12-18s and then again at 40-46s. It is hard to hear because of the wind noise, but I can't figure out how to isolate the noise any better. If anyone has any ideas, I would sure appreciate the input. The water pump was just replaced, and so was the alternator, along with the tensioner pulley. I admit my limited knowledge under the hood, but I am willing to learn and fix it, if I can.
