and Yukon XL in order to fix a "transmission oil cooler line that is not securely seated in its fitting," causing the vehicle to stop and rupture the oil cooling line, resulting in the engine to malfunction and catch fire immediately. The move comes on the heels on an incident that happened on March 23, 2014, when a 2015 GMC Yukon caught fire in Anaheim, California during a test drive. Despite being an isolated incident, the 2015 Suburban and Yukon XL are not tied to GM's announced recall of its vehicles (from previous generation models and discontinued brands that were produced prior to, during, and after GM's restructuring in 2010) that was made on March 17, 2014. On June 6, 2014, GM issued another recall on the 2015 Suburban and Yukon XL because their radio control modules may not work, and thus prevent certain audible safety warnings. This would be followed on June 27 with another recall, in which the transfer case "may electronically switch to neutral without input from the driver," adding that if this occurs while the vehicle is moving, power will not be sent to the wheels, meaning that if the vehicle is parked, it may roll away unexpectedly if the parking brake has not been set. On December 5, 2014, GM announced that it is replacing ignition key units on the 2015 Suburban and Yukon XL after customers made complaints that the shift lever strikes the head of the key if the tilt-adjustable steering column is in the fully up position. The lever only can be moved out of "park" into a gear when the engine is running and the driver's foot is on the brake. The push-button ignition features are not affected. On January 4, 2015, GM issued a recall on tenth-generation Suburbans and Yukon XLs from the 2011 and 2012 model years for a potential ignition lock actuator issue, citing that they are not the right size and can cause the ignition to get stuck in the "Start" position, and then either due to a jarring event or a "cool interior temperature" the ignition could switch back to the "Accessory" position, resulting in a loss of power assistance and prevent the airbags from deploying. On December 30, 2015, the NHTSA revealed that it had received complaints from 2015 Suburban/Yukon XL owners about buffeting and vibration problems causing drivers and passengers to endure an annoying
