AIR BAGS
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 BRAKES
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.

ELECTRICAL SYSTEM
I turned on my rear defroster. I smelled electrical burning and rear window shattered with my 6 month old in the back seat in her car seat. GM states there is a recall which can be referenced as N192220470. Speaking with customer service and dealership the recall is VIN specific and my vehicle is not included in the recall even though the year and make is listed in the recall. Very dangerous, especially when there are passengers in the back seat of the vehicle

UNKNOWN OR OTHER, ELECTRICAL SYSTEM
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
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.

ELECTRICAL SYSTEM, STEERING, ENGINE
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
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.

SERVICE BRAKES, ELECTRICAL SYSTEM
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.

POWER TRAIN
I bought my 2015 gmc sierra 1500 certified and since then it has had vibrations when driving and hard shifts. The dealer has looked it over many times and said it's normal. Last month they said they sent gmc the readings and I haven't heard back. They have lied to me before about other vehicles and I'm tired of dealing with them not fixing it.

ENGINE, POWER TRAIN, UNKNOWN OR OTHER
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.
