Fiat Chrysler Recalls 1.3 Million Ram Pickups For Fatal Software Problem (cnn.com) 101
An anonymous reader quotes a report from CNNMoney: Fiat Chrysler is recalling 1.3 million pickup trucks because of a software problem that may be tied to at least one death and two injuries. The problem could disable side airbags from deploying and seat belts from tightening in a rollover accident. If there is a significant impact on the truck's underbody, Fiat Chrysler says the truck's safety system could incorrectly conclude that a sensor underneath the truck has failed. If a sensor does fail, the truck's safety system is designed to suppress the airbags from deploying and seat belts from tightening when they are not supposed to. That's why there is a risk if there is a subsequent rollover. The good news is the driver should be alerted to this problem by a instrument cluster warning light. If the light comes on, drivers should then turn the truck off, and then turn the key back into the on/run position to verify that the light is no longer on. They should also follow instructions on their recall notice. The report notes that the affected vehicles include the 2013-16 Ram 1500 and 2500 pickups, and 2014-2016 Ram 3500 pickups.

This is a system problem, but it's that the control system is incorrectly diagnosing a sensor failure, not that it is suppressing air bag deployment in response to the detected failure. There are only very specific instances where you actually want the airbags to deploy. In the event of failure of a sensor that degrades the ability to determine if airbag and/or pre-tensioner deployment, the fail-safe option is to disable the air bag system to prevent a spurious deployment, and light the warning indicator in

From the other articles on the subject, it appears that the impact to the bottom of the truck body has to be pretty good, like hitting a big rock, or something similar. This, coupled with the sensor failure setting, is a problem, but the Dodge pickups are like most trucks on the road, built a bit better than the flimsy cars. Meaning, the quality of manufacture may vary slightly, but a truck is first and foremost meant to be a truck.

Actually, the sudden deployment of airbags and the seatbelt tensioner would be far more unsafe than to not deploy in an accident.
Beside the startle factor, it's a fairly violent event and it's far safer that in case of problems, the airbag does NOT deploy than deploys.
It's why we have airbag disable switches, and children sets are never allowed in the front seat anymore - because deployment has the chance to cause injury.

With almost all airbag fatalities its usually due to people putting their arms over the steering wheel (I.E. hand over hand) rather than doing push-pull steering.

No they designed it in the safest possible way. When designing safety systems whether they be for fire and gas in buildings, nuclear power plants, or for a small FIAT you have to take into account several risky scenarios. One of those scenarios is the spurious operation of the safety system.

When you blow a head gasket, you simply look for a 2nd hand replacement engine. A Ford Mondeo/Taurus uses Fords most common engines, An engine swap shouldn't be more than a days labour at the most. I once got a Nissan SR20DET completely replaced for A$2250 which included a new radiator and turbo.

Risk evaluation (Score:3)
Just interesting how we react to safety issues and recalls and have no real concept of statistics and risk evaluation. So of the 1.3 million Ram trucks on the road covered by this recall, many of which have been safely driven for several years, only 1 death has occurred because of this and 10 injuries confirmed. So that's a reliability rating of some five 9s, which fro a purely capitalistic point of view is actually well within reason and a perfectly acceptable death rate (unless of course it affects you!). Your odds of dying in a car crash despite working safety features are orders of magnitude greater than dying in a crash in a vehicle with this flaw where this flaw caused your death. So how do we evaluate the true risk and true cost?
So on the one hand a correctable flaw probably should be corrected, but on the other hand, if the odds of it happening are near zero, from a completely economic point of view it'd be far better for the companies and the economy to do nothing and let people die at the present rate. Is the latter action morally wrong? It may be. Depends on how you evaluate the risks. Forced recalls seem like a great idea because a company is forced to foot the bill and learn from it, but in reality the costs will be passed on to consumers down the road. I do wonder where this continual threat of litigation, particularly by the NTSB, is going to lead us. Might make us safer, might just make us spend more money.
