General Motors LLC (GM) is recalling certain 2015-2016 GMC Sierra 1500, 2500, 3500, and Chevrolet Silverado 1500, 2500, and 3500 trucks. The roof-rail air bag (RRAB) inflator end cap may detach from the inflator, or the inflator sidewall may rupture.
A separated inflator end cap or inflator rupture can allow compressed gas to escape, resulting in the end cap or other components being propelled into the vehicle, increasing the risk of injury or crash.
Dealers will replace the left and right side RRAB modules, free of charge. Interim owner notification letters informing owners of the safety risk were mailed on August 18, 2021. Owners will receive a second notice when the remedy is available. Phase I owner notification letters were mailed on May 5, 2022.

General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.

2015 Chevy Silverado, 62,300 miles. While driving at highway speeds. The air condition compessor locked up. Causing the engine to die and causing the loss of power steering and power brakes. I was unable to brake in a timely manner and had to swerve to avoid stopped traffic. It seems there are thousands complaining of the same issue online. There was no warning. I have contacted the dealer and they say there is no recall.

When going at low speed, power braking fails, and I have almost crashed my truck several times. Also - when going at low speeds, my electronic power steering fails - it's difficult to turn and the steering wheel "kicks back" in my hands. Extremely difficult to turn. I'm very concerned that these two things will lead to a crash/accident. Please help! The approximate date listed is the last time these two issues occurred - but it occurs almost every time I drive the vehicle.

Steering, Electrical system, Engine, Jan 10, 2022
While slowing down to make a right turn the engine stalled and the electrical power was lost rendering the power steering inoperable. The loss of power steering created a dangerous situation where I almost hit a tree. Also there has been several occasions while driving on the freeway the electrical power stalled. Thankfully it was only for less than two seconds, but I can't imagine what would have happened on a busy freeway had it not been only a temporary loss of power. I read online that these problems are not uncommon. I have taken the truck to a Chevy dealer where they replaced battery cables they said had some resistance in them. It's been a month since the repair ($1300 later) was made and have not experienced any problem since. After experiencing these "power failers", there would be a message on the dash that would state "OPEN THEN CLOSE DRIVER WINDOW'

I estimate this has happened over 10 times. I lose all electrical power to the vehicle and the car shuts off, often this is preceded by loss of power steering and low speed. The last time this happened when pulling out into traffic; the steering kicked back, the truck lost all electrical power, dash went blank, radio dark, including loss of head lights, I will reiterate that this happened while pulling into traffic. This truck cost me over $40k new and I believe Chevy is aware of the problem, then simply don't want to cover the cost of parts and labor to fix. The dealership told me they had no idea what the issue could be, then I found several GM documents online. It appears this is a known issue, and they even list 2015 Silverado on documents. Bulletin No.: 18-NA-161 (The issues in this match exactly what I've experienced) also Reference Number:N172085440 Please help me convince Chevrolet to fix this issue or force them to do a recall.

Steering, Electrical system, Jul 22, 2021
The 2015 Chevy Silverado has a very common problem, which I am shocked has not been put under a nation wide recall. A manufacturing issue of placing the negative battery cable in the wrong spot, causes the dash, power steering, stability tracking and air conditioning to shut off completely. When braking, the dash shuts off and the steering wheel locks, which has sent me into oncoming traffic. My brother had the exact same year make and model of truck and had the same exact issue. When his needed to be fixed, he was told the same thing from the dealership. “The negative battery cable should have never been in placed in that position, but relocating it will fix the problem. Only, after replacing the battery it burned out as well. Here is the text I received from the dealership today. “Hey Brian, this is Matt @ Ken Garff Chevrolet, we have tracked the problem down on the truck to the negative battery cable. It has high resistance causing the electrical issues. Estimate for repairs $492 before tax. Reply STOP to OptOut.” It’s a very good thing they diagnosed the issue, since I told them what it was when I walked in their shop. I told them verbatim what they sent back to me. There are literally thousands of complaints online with the same issue. How does a manufacturing fault, that is most definitely a safety issue, become the consumers expense. This problem is much worse, and more dangerous than the recalls that are currently on the vehicle. How many accidents and how much consumer money needs to be spent, before a recall is placed on such a common manufacturing issue. Please let me know what needs to be done to get this taken care of, so more people aren’t in danger, or screwed into paying to fix a blatant error by the manufacturer.

My truck shakes frequently going down the road at certain speeds. I've had it for around 6 years now and I can't pinpoint exactly when it started. I've had the truck in for maintenance/service at the dealership as well as other auto shops trying to diagnose the problem. I've had new tries, new brakes, countless tire rotations, wheel balancing etc you name it. And the problem persists. Recently after hearing about the "Chevy Shake" I've come to realize that my problems are just like what others have too. Now my powertrain has given out. And my extended warranty has ended. I truly believe that the issues have caused, or are caused by this prevailing issue of a wobbling drive shaft. Every time I have had it in for repairs the issue still persists and I can't always get the time to go back and have it looked at it again. It is a safety issue above all else and I truly believe GM knows about it but does nothing. Even more to the point, I had a "transmission fluid flush" just under a month ago and now all of a sudden my truck doesn't shift like it should. They say it will cost over 5 thousand dollars to get repaired. There is something seriously wrong here. This is an ongoing issue, and again it is difficult to say when it started. But a vehicle going down the highway at speed limit and shaking is a safety concern.
