Got a 2 week old 2021 Yukon Denali. Has anyone else experienced the non-stop "Service Safety Restraint System" alert? This goes off about every 2-3 minutes in mine. Taking to dealership this week, but checking to see if anyone has experienced same issue and if their dealership found a fix.

Just bought 2021 Yukon Denali and after leaving dealership, I am having the same issue with "Check safety restraint system" warning. It is constant. Dealer has vehicle but no fix after two days. Will advise if repaired and how.....hopefully soon!

I have had my Denali 3 weeks.  Same issue.  Took it once, no fix.  Here now, and they said it is a software update that hasn't gotten pushed to them yet.  I've seen on Tahoe forums it was a seat issue with the wiring.  I'm not sure which it is, but thinking I may take it to another dealer if they don't seem to know what it is here.

There's seemingly been a few different sources of issues. I've also seen one or two that got a software update to fix, another the steering wheel airbag module, and yet the others with the wiring issue in the seat (document number/info is on the tahoe/suburban site that you likely found by now)

Don’t  know of any software update, but there is an updated wiring harness and connector for the driver seat. There is a bulletin for this, I’ll find it later.

2021 Denali. Same problem here. Took to dealership about two weeks ago and was told it was a “coil” (I’m a woman and of course fell for this) but a week later mine has started giving me the same alert. Nonstop. I also have an issue with my buttons on back of steering wheel to change stations. Works sometimes. Doesn’t sometimes. When talking on the phone thru the car - sounds like someone is underwater.

you didn't fall for anything. The SIR Coil/Clock spring has been the cause of some of the error messages you are seeing. There's been two sources of the error, thus far. One is the steering wheel SIR Coil/clockspring and/or the steering wheel airbag module. The other source is the inboard driver seat airbag connector. Is the button issue new?

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.

      I can't believe that could possibly be the case. It should be 36mo/100k miles from installation. Then again, it also seems like since a dealership installed it, it'd all be in the system and you wouldn't need to worry about registering, either. Shows you what I know. 😄 Hope this one outlives the warranty!

      I haven't seen inventory recovery from COVID.    In the few random times I 'build my own' truck or SUV, no one has the exact one I want.   GM has been working to lower incentives too for a long time.    A $500 incentive isn't getting me off the couch to go truck shopping.
