Is there a problem with Mercedes air bags?

Has Anyone Else Had This Happen to Their Mercedes GLA? Airbags Didn't Go Off in a Head-On Crash.
Salutations, tous,
Ideally, I'd be able to benefit from the wisdom and insight of other Mercedes owners.
The other driver was careening across the road on October 1, 2025, and my daughter was in a terrible head-on collision as a result.
Due to the severe frontal damage, her Mercedes GLA was deemed a total loss. My daughter's Mercedes did not have its airbags deployed, but the other vehicle, a Toyota, did.
Tragically, she suffered a knee injury, psychological effects, whiplash, and fractured ribs. She is still going through treatment and dealing with issues that she had over a year ago.
After inspecting the car, Mercedes-Benz UK determined that parts of the radiator, slam panel, front bumper, and bonnet had been pushed backward toward the engine. Airbags and pyrotechnic seatbelt tensioners did not activate, but the active bonnet/pedestrian protection system did, according to their confirmation.
According to Mercedes, the accident did not satisfy the conditions for airbag deployment, and there was no malfunction or defect.
I am not claiming to be an expert on automobiles, and I do understand that airbags aren't meant to deploy in every accident. But my daughter was hurt, and the damage is so bad that I just want to know when they should or shouldn't activate.
I don't know if this is relevant, but the car had been to a Mercedes dealership before after a 2019 recall involving the airbags.
Mercedes-Benzes have a long history of safe transportation among my extended family and friends. Actually, we went ahead and bought another Mercedes to replace my daughter's car despite this whole ordeal.
Accordingly, I would find it extremely intriguing to learn:
Have the airbags ever failed to deploy in a serious frontal collision involving a Mercedes?
How about the active bonnet system or seatbelt tensioners? Has anyone else encountered anything similar?
I was wondering if any Mercedes owners or technicians had any insight into the factors that decide deployment of the SRS system.
After an incident like this, has anyone ever gotten a second opinion from a technical expert?
Additionally, I would be very interested in learning what kind of crash or event data a 2018 GLA might store after a collision.
I don't mean to imply that anyone is to blame or criticise Mercedes. My only goals are to get to the bottom of what happened, hear other owners' stories, and, with any luck, feel better about the safety features that we all depend on.
Whether shared publicly or privately, any advice, technical know-how, or experiences would be greatly appreciated.
My deepest gratitude in advance.

Everyone who has read my post, shared their stories, and offered advice in regards to my daughter's accident has my deepest gratitude.
My only concern as a father was making sure my daughter was safe in her Mercedes and that all of the safety features worked as they should have.
Her Mercedes GLA was totalled after a terrible accident on October 1, 2025, but the airbags and pyrotechnic seatbelt tensioners didn't go off. The airbags in the other car deployed.
My daughter was severely hurt physically and emotionally, and she is still dealing with the aftereffects of those things more than a year later.
According to Mercedes-Benz, the accident did not constitute a malfunction and the airbags did not deploy. While I get that airbags aren't meant to go off in every single crash, the given details still have me worried and unconvinced.
Mercedes-Benz has been a part of our family for three generations. Due to their exceptional engineering, performance, quality, and safety reputation, Mercedes vehicles have been driven by my grandparents, parents, and now my own family.
We were still so committed to the brand after the accident that we went ahead and bought my daughter a second Mercedes.
Unfortunately, that self-assurance has now vanished. Both trust and faith in Mercedes-Benz have eroded for me. As a result, we're ending a three-generational family tradition by switching to a different vehicle manufacturer as soon as possible.
Also, I'm realistic about the challenges of taking on a big manufacturer after reading the stories and recommendations on this forum. I am no longer employed and do not intend to engage in a drawn-out and possibly expensive conflict with Mercedes-Benz.
Having said that, I am not obligated to keep quiet. I plan to tell other parents and drivers about my experience on social media so that they can form their own opinions. I want to make sure that no one's reputation is unfairly hurt, but I do want to bring attention to the safety systems that we rely on and encourage that they be more transparent.
The worth of a totalled car has never been an issue here. My first priority has always been making sure my daughter is safe and finding out what could have been done to lessen the severity of her injuries.
I felt a responsibility to my daughter as her father to investigate the accident thoroughly, even though I was powerless to stop it. So far, that's been my sole endeavour.
My deepest wish is that no other parent ever has to deal with anything like this.
Thank you to everyone who has provided guidance, expertise, and encouragement. We are truly grateful for your generosity and the things you have done.

I recently read about a Hyundia that failed to deploy its bags in a much more serious accident than the relatively minor front end damage your daughter sustained (see picture). He lost after going the legal route. Although the vehicle was travelling at a speed that exceeded the regulations, the on-board diagnostics provided evidence that the airbag deployment criteria had not been satisfied because the impact was too severe and too far off-center. Thankfully, the two of them only suffered minor injuries.

The airbags won't deploy until a number of conditions are met. Both the impact speed and angle must be sufficiently high, typically exceeding 16 mph. Too high, too low, etc., is the impact point. Good luck with your endeavour! Just a friendly reminder to be very careful with what you post on public platforms like Facebook and ensure that all of your facts are accurate. Sadly, I used to know a man who went to the hospital after a motorbike frame failed; he is no longer with us. He made a highly public appearance. Since it was clearly not Suzuki UK's fault, he had to apologise and implore them not to sue him. I must express myself!

Impressive Opinion
Many thanks

 I was going to bring up the fact that any criticism of MB could potentially lead to a lawsuit in the absence of concrete proof of vehicle defects.

Just curious: is there a standard for when airbags should deploy, like in the UK, the EU, NCAP, or somewhere else?

AI response...
The EU General Safety Regulation (Regulation (EU) 2019/2144) governs the deployment of airbags in passenger cars within the EU. This regulation ensures that these cars comply with specific crash-test regulations set by the UN Economic Commission for Europe (UN ECE). In standardised crash tests, the European Union establishes stringent biomechanical injury limits that manufacturers can only meet with correctly calibrated airbag deployment, instead of mandating a universal G-force or millisecond trigger threshold.

Is a seatbelt attached?
