1 Air Bag problem

Failure Date: 12/01/2025

Vehicle: 2021 GMC denali mileage: ~48,000 miles purchase price: $62,000 issue: airbags & crash sensors failed to deploy complaint text: I am filing a safety complaint regarding my 2021 GMC denali. I was involved in a rear-end collision at approximately 45 mph, where I struck another vehicle straight on from behind. The impact was severe enough to total my vehicle, yet no airbags deployed, and no forward collision warning or crash sensor systems activated. This is especially concerning because this vehicle was previously involved in a front-end collision (not my fault) and underwent extensive repairs. I was assured all systems were repaired and functioning properly. Additionally, my vehicle had completed recall work related to safety systems prior to this crash. This is the second front-end crash involving this vehicle where airbags failed to deploy. Given the speed and severity of the impact, airbags should have deployed. The failure of these systems placed my life at serious risk. The vehicle has since been totaled and taken by insurance, but I am requesting that this failure be formally investigated as a potential safety defect in the airbag and sensor systems. I am extremely concerned that the vehicle’s safety systems were either defective or not properly restored following repairs and recalls.

2 Air Bag problem

Failure Date: 10/03/2025

“service safety restraint” light comes on and the dealership cannot pin point exactly what the issue is without taking the entire seat and air bag out. It’s come on 3 times. First time was linked to the overhead console needing replaced. Months later the light came on again and a seat harness connection was bad. It was replaced and light was off. 8 months later the light is back on again and they replaced the connection again and the light is off for now. This is a safety issue and should be a recall!.

7 Air Bag problem

Failure Date: 06/24/2024

There are apparently a couple of faults affecting the srs and leading to a periodic airbag light and "service srs" warning. Gm has issued/revised a few service bulletins related to this warning. Some are related to software, some are related to overhead wiring, some are related to the clock spring in the steering wheel, and some are related to the driver's side airbag module. My understanding is that when the srs warning appears, all airbags are disabled and gm says we drive our vehicles at our own risk. To my knowledge this has affected several models of approximately 2021-2023 GMC (yukon and sierra) and Chevrolet (tahoe, suburban, silverado) suvs and trucks.

Service safety restraint system came on my vehicle and I just purchased this vehicle 3 weeks ago.

9 Air Bag problem

Failure Date: 05/29/2023

The SUV shown safety message, it was diagnosed with airbag not deployed. This is very important specially for the rear backseat. GMC doesn’t want to be responsible and makes customer pay.

10 Air Bag problem

Failure Date: 11/14/2022

The vehicle has 22,000 miles on it and is under warranty. The airbag light indicating a malfunction stays on. The vehicle has been to the dealer 2 different times. The dealer indicates the factory(GMC) is working on the problem but has no solution at this time. Researching I have found this to be a problem for years not just the 2021 model. I have asked the questions: do my airbags still work in a collision? can the airbags inflate by mistake? I’m a grandfather and have young children in the car. Are they safe? no one will give me a firm answer. Know what if I want to sell the vehicle? can’t do it? someone needs to make GMC accountable. Peoples lives are at risk with this issue.

11 Air Bag problem

Failure Date: 11/10/2022

Service safety restrain system message keeps appearing after taking to dealer a few times. It will go off and on intermittantly and not sure the airbags are actually functional. This seems to be a common issue based on an internet search across multiple gm products that does not have a known fix. Also, the driver seat shifts slightly when making turns.

14 Air Bag problem

Failure Date: 10/06/2021

I was involved in a vehicle accident on 10/6/2021 where my vehicle was stuck by an uninsured motorist driving recklessly on the interstate causing a total of 4 car collision. My vehicle was a a 2021 GMC Yukon slt SUV, in which I was struck on rear drivers side quarter panel and again by another vehicle in the front bumper by another vehicle that struck in the rear bumper by the reckless driver. With my vehicle being struck by two vehicles I was shocked to learn the onstar safety security features did not detect or contact me regarding the accident. It wasn’t until the wrecker driver arrived to pull my vehicle onto the tow truck that I received a diagnosis notification email from o star about my antilock braking system. Although I was wearing my seat belt, the impact of the collision was very shocking, my chest and neck struck the steering wheel, my glasses were knocked completely off my face on to the passenger side floor board, my personal belongings in the passenger seat, were thrown and scattered over the passenger floor area. Once the emergency authorities were on the scene everything was about over I contacted onstar via phone, and asked why wasn’t I contacted or my accident detected, and the call taker/on star representative advised me because my airbags wasn’t deployed, they did not receive a notification or alert regarding my emergency. I have attempted to make contact with onstar several times since the accident and as of today I have yet to get an answer of why my air bags did deploy and why the emergency sensors did detect the impact notify emergency services as this is a feature that I was charged for monthly and added protection that I counted on to assist me but very much failed me at my time of need.

15 Air Bag problem

Failure Date: 07/04/2021

Once again, the car has been repaired under the recall for the airbags, but once again the cars lights have turned on to state service safety restraint system. I am unable to trust the airbags will deploy with the system being that this issue has been appearing multiple times and reappeared after the recall was complete.
