Air bags, side/window, curtain, inflatorJul 1, 2021
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. Phase II owner notification letters are expected to be mailed on May 31, 2022. Owners may contact GMC customer service at 1-888-988-7267 or Chevrolet customer service at 1-800-222-1020.

Seat belts, frontApr 8, 2021
General Motors, LLC (GM) is recalling certain 2014-2016 Chevrolet Silverado 1500, 2015-2016 Chevrolet Tahoe, and 2014-2015 GMC Sierra 1500 vehicles that may have received an incorrect replacement tensioner cable assembly as part of a previous recall remedy or a subsequent repair. The flexible steel cable connecting the driver's seat belt to the outboard side of the seat may be repeatedly bent over the seat side shield as the driver enters and exits the vehicle causing the cable to fatigue and separate.
A broken pretensioner cable reduces the effectiveness of the driver's seat belt, increasing the risk of injury.
GM will notify owners, and dealers will replace the driver seat belt lap pretensioner, free of charge. The recall began on May 5, 2021. Owners may contact Chevrolet customer service at 1-800-222-1020, and GMC customer service at 1-800-462-8782. GM's number for this recall is N212330040.

Service brakes, hydraulic, antilock/traction control/electronic limited slip, wheel speed sensor/tone ringOct 24, 2019
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.
GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.

As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.
GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began October 8, 2019. 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. GM's number for this recall is N192268490.

While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017.

GM issued a recall notice on July 1, 2021, regarding the rear curtain airbags in my Sierra. To this date (12/27/21), they have still not provided an ETA for getting this remedied. I called the dealership in September, to which they stated it would be another month before they could address it. I am wanting to be proactive to get this issue remedied, but the delay is unacceptable. I am escalating this to get some traction.

Service Trailer Brake Brake System error keeps flashing.
Service brakes, Dec 17, 2021
The component that malfunctioned is the vehicle braking system at slow speeds. I first experienced the problem at a restaurant drive thru line. After several stops as the line advanced, the braking system failed (extremely hard pedal) and car kept advancing and if someone would have been directly in front of me ( at a normal distance for a drive thru ) I would have made contact with them at a slow speed. I checked with my dealer the next day and they said that there were no reported problems for this issue on my vehicle. No warning lamps or messages present but it seems to me to be similar to the recall ( N192268490 ) as it only happens at slow speed with repeated application of the brake. There were no symptoms of the problem prior to this incident and it took me completely by surprise. I took the vehicle in to a service facility and they test drove it and said that they did not recreate the failure but I believe that they didn't try repeated braking at slow speed as I requested. I feel that there is a problem and that it only shows up during the aforementioned driving conditions. I have checked your website and the manufacturers and my truck VIN doesn't show up for their computer reprogramming recall but think that maybe it should.

My back window just made a loud pop sound. I have a back window that had an electic sliding widow. Which means the back window is in 3 sections (driver side, middle sliding window, and passenger side). The driver side of the back window was completely shattered. It's hard to see from the outside but from the inside it is spider cracked everywhere. I believe that I had my rear defrost on at the same time. Nothing hit my window to cause this.
Electrical system, Dec 5, 2021
I had my rear defrost on and it started smoking on the rear drivers side window and smelled like something burning and I parked at a gas station a couple of minutes later. The rear window completely shattered. The glass stayed intact but my 6 year old son was sitting in the backseat and it scared him half to death. I looked up recalls and this is known issue with these vehicles sold in Canada. This just happened and it hasn't been looked at my anyone.

Truck will experience complete electrical failure while driving in motion at various speeds. Failure lasts between 5-10 seconds but causes severe difficulty as steering is affected. A web search reveals grounding issue as potential cause. Manufacturer has not notified me of this particular issue and or any recall effort and I know of no existing recall effort for this issue.
Steering, Nov 24, 2021
Becomes hard to turn steering wheel at slow speeds, more often while in reverse. On one occasion, a Stabilitrak message popped up as a warning and then the engine died. Does not happen every time but has happened enough to take it to the dealership. They concluded that it could not be duplicated so they could not properly diagnose the issue. They had the truck for 3 days of testing. The engine failure is seriously concerning to me due to having my children with me most of the time.

Trailer Brake system warning continues to pop up on my dash along with the chimes. Not sure if this will affect my braking or not, but I pull a 32' camper and am continually concerned about this warning. It happens randomly not just when towing a camper. It has been in to a GMC dealer and they say nothing can be done about it due to no recalls.

While operation my 2015 GMC 1500 DENALI Pickup at normal conditions my vehicle produced a engine light. I was three blocks from my office so I proceeded there immediately to have my vehicle scanned for codes. This is where I found out that cylinder #7 had an issue. This cylinder is part of the AFM system. I had the vehicle towed to Galles Chevrolet for diagnostic services and an estimate for repairs. Up receiving the results (which) I will attach. Bank 1 and possibly Bank 2 lifters and springs have failed. Thus possibly cause damage to the cam shaft. While I am aware that my vehicle is out of powertrain warranty (5 years / 100,000 mile), my vehicle only has 52,000 miles on it and very very well taken care of at all times. I am also aware of a class action law suite that pertained to the same exact issue on gm products from 2004-2014. Also service bulletins were produced by GM pertaining to this issue. Now I have been out of service of my vehicle for 3 1/2 weeks not to mention a potential $7000 repair, that should have never been in the picture! Poor quality control on products for potential profit gains have cost many many customers pain, anguish, and money.

The first issue is popping coming from the front end of the vehicle causing a steering issue. This has been "repaired" multiple times with no resolution. Every time the popping occurs which is almost every turn the steering wheel will not turn. The next issue is the radio is causing driver distraction by changing stations and screens not just on the display itself but the instrument cluster as well. The radio has been replaced once due to the fact it was on backorder for 6 months another attempt has not been made. The third issue is the brakes have failed at slow speeds no warning lights were on, they just stopped working in the Mcdonald's drive-through. I had to get out of line to keep from rear-ending the person in front of me. Now, after that experience, the ABS light has come on and the service StabiliTrak flashes on the dash as well as parking assist off, everytime I hit the brakes. .
