Ignition switches: mechanical flaws meet sensing algorithm

Earlier this year GM recalled many vehicles due to faulty ignition switches. The ignition switches can easily be knocked out of the "run" position into "accessory" or "lock" position, resulting in a partial loss of electrical power and turning off the engine. Power loss could mean the airbag wouldn't deploy.

The timing of the key movement out of the "run" position, relative to the activation of the sensing algorithm of the crash event, may result in the airbags not deploying, increasing the potential for occupant injury in certain kinds of crashes. – letter from GM to NHTSA

The problem affects Saturn Ion (2003-2007 models), Saturn Sky (2007-2010), Pontiac G5 (2007-2010), Pontiac Solstice (2006-2010), Chevrolet Cobalt (2005-2010), and Chevrolet HHR (2006-2011). Reuters has a good timeline and reports that 107 death claims have been filed.

Air bags: flawed sensing & diagnostic modules

To fix a part in the sensing and diagnostic module that controls vehicle air bags, GM is recalling 2014 and 2015 Chevy Silverado, GMC Sierra, Chevy Suburban and Tahoe, GMC Yukon, and Yukon XL models. The part was "suspect," says Automotive News.

Again with the SDM: GM said in a statement that it is recalling "33 model year 2014 Chevrolet Corvettes in the U.S. because an internal short-circuit in the sensing and diagnostic module (SDM) could disable frontal air bags, safety belt pretensioners and the Automatic Occupancy Sensing module."

Engine stall tricks powertrain control module

Mazda is recalling the 2014 Mazda 3 and 2014 through 2015 models of the Mazda 6 because charging system shutdown may cause engines to stall, according to the NHTSA. The problem is caused if the alternator belt slips, causing the power control module (PCM) to incorrectly assume failure of the charging system.
