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:
Hey folks, first time posting here and maybe it’s a common thing. I’ve searched google and YouTube for days, replaced parts, and done the troubleshooting I know to do. So here it is, bear in mind, im no auto mechanic. I’m a jet mechanic/toolmaker. Lol
my front pass brake locked up Friday, and the abs/parking brake light has been on since the dealer I got the truck from replaced the parking brake cable. I don’t hear a roaring, so I don’t feel like it’s a hub, but I do have some bouncing on the front end which leads me to think it may be an axel, which I still have to get looked at.
parking brake and abs lights come on after a few seconds of driving, I hear brakes grinding, and I just replaced both front rotors, pads, and passenger caliper and abs sensor after it locked up; since it melted the abs sensor cable.
brakes are bled properly and working, but they aren’t fully releasing. I’ve checked fluid, it’s not overfilled. Driver hub was previously replaced but not passenger for some reason. I considered ordering a hub for the passenger side just for that. Rotors are 305mm and the pads I installed are ceramic from brake best. Yes, the rotors get hot after a short drive, like too hot to touch. I’d rather not have these things lock up on me again. The only thing left I know to check are the piston in the master cylinder, or the passenger hub.
Any ideas? If I’ve missed good reference material or prior posts please feel free to comment with a link and a nice “check here dumbass.” Lol
thanks in advance.

Hey guys I’m new to the forum as well the brand. I recently just bought a 2019 custom trail boss which only offers the 5.3. I wanted the 6.2 but that came with only the higher trims. I’m familiar with the 5.7 hemi and I’m kinda down about the 355 horsepower/ 383 torque compared to my hemi that I traded. What can I do exactly to get more power to the engine?

Hey guys, i have a 2005 gmc yukon with electric fans. It is the 5.3 and the electric fans will not turn on. I have replaced the coolant temp sensor and the relays and it is still inop. If i send 12v to the fans they will turn on and constant power is getting too the two 4 prong relays my tools will not fit to test the 5 prong. None of the fueses are blown either and relays have resistance to them. It has a slight hickup on startup but not much of one and sadly no they do not work with the ac on the temp will go straight past 210 when parked
