GM recalls Chevy Impala, Cadillac XTS for braking problem

Back in April, General Motors launched an investigation into braking issues affecting the 2014 Chevy Impala. Now there's a recall of both the Impala and the Cadillac XTS with which it shares its Epsilon II platform.
The issue apparently revolves around the electronic parking brake, which may not properly disengage. As a result, the rear brake pads could rub the rotor even while the vehicle is in motion, causing "significant heat, smoke and sparks." The earlier investigation had been launched following a complaint regarding the forward collision avoidance system, which is now either appears to have been unrelated or possibly a symptom of this larger issue.
The recall affects 2013-15 XTS models manufactured between February 14, 2012, and August 22, 2014, as well as 2014-15 Impalas manufactured between January 15, 2013, and August 22, 2014. The total number of affected vehicles reported by the National Highway Traffic Safety Administration comes to precisely 132,921 units, while The Detroit News reports a higher total of 205,000 units - the difference potentially coming down to the scope within the US and more broadly across North America. Dealers will contact owners to update the software in order to fix the problem.

GM recalls 3.6 million vehicles for airbag-software problems

The Basics: General Motors is recalling 3.64 million vehicles across its lineup for an airbag-related issue. The recall covers the 2014-2015 Buick LaCrosse, Chevrolet SS, and Spark EV; 2014-2017 Chevrolet Corvette, Trax, Caprice PPV, Silverado 1500, Buick Encore, and GMC Sierra 1500; and 2015-2017 Chevrolet Tahoe, Suburban, Silverado HD, GMC Yukon, Yukon XL, Sierra HD, Cadillac Escalade, and Escalade ESV. The Problem: Affected vehicles have a sensing and diagnostic module that controls the airbags and seat-belt pretensioners. The software it uses has a defect that can prompt the module to run a diagnostic test under specific driving conditions, which will also deactivate the front airbags and pretensioners. This means that it would be possible for those safety systems to not activate in a crash, potentially leading to injury or death. Injuries/Deaths: General Motors began an investigation that led to the recall after a 2014 Silverado was involved in a crash in which the airbags did not deploy. No information was given as to injuries or deaths. The Fix: Owners can bring their vehicles to a local General Motors dealer where a software update will be installed to fix the issue. The fix will be free of charge. If you own one: General Motors will contact owners of affected cars, and owners can check whether their vehicles are affected by visiting entering their vehicle identification numbers at either the GM Owner Center website or the NHTSA website. Owners can then schedule a time to have the update installed. Related Video:

GM recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.
