General Motors has issued two recalls affecting roughly 250,000 Chevrolet and Hummer vehicles, 210,000 of which are registered in the U.S. The Hummer recall is the larger of the two and has been linked to 42 fires caused by part of the SUVs' climate control system.
MODELS AFFECTED: 2006-10 Hummer H3 and 2009-10 Hummer H3T
UNITS AFFECTED: 196,000 (165,000 in the U.S.)
This recall stems from a faulty connector module that manages the speed of the blower motor in the Hummer's climate control system. GM says that under certain conditions, the module can overheat and catch fire.
To date, the company has received 42 reports of such fires and three related injuries. However, the company knows of no accidents or fatalities linked to the problem.
GM will notify Hummer owners about the recall by mail. After receiving a recall notice, owners will be able to take their SUV to an appropriate dealership for service, where a portion of the connector module and the wiring harness will be replaced at no charge.
MODELS AFFECTED: 2014-15 Chevrolet Spark and 2015 Chevrolet Sonic
UNITS AFFECTED: 50,731 (45,000 in the U.S.)
This recall is the result of buggy software powering radios on Sparks and Sonics. According to GM, that software can cause problems in vehicles equipped with both a base radio and OnStar. Specifically, when OnStar is in turn-by-turn navigation mode, the software can cause the radio to freeze and the display screen to go blank.
That in itself might not seem so bad, but the glitch also disables audio functions like warning chimes that sound when passengers haven't buckled up or when drivers leave their keys in the ignition switch. In some cases, even though the screen is blank, the radio may remain on after the vehicle is turned off, which could drain a car's battery.
After receiving recall notices in the mail, owners will be able to take their vehicles to a Chevrolet dealer, who will reboot the radio software at no charge.
