2012 Chevrolet Tahoe ProblemsHeating and AC Temperature and Air Delivery Mode Door Actuators May Fail
One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.
"SERVICE TIRE MONITOR" warning came up, when I took it to the dealership they told me all 4 monitors were bad...I questioned how all 4 could go out at the same time and they told me that it was unusual but their computer is getting the same code for all 4. They suggested I start repairing one by one...just does not make sense to me. I think they are not using the right computer code or something...They quoted over $600 to repair.
The steering wheel position sensor may fail, resulting in the service stability message being displayed.
2012 Chevrolet Tahoe RecallsIgnition Switch
The ignition switch actuator can bind causing the ignition switch to stick in the "start" position. If this were to occur the actuator can unexpectedly release, cause the ignition switch to snap back into the "Accessory" position. This would cause the engine to turn off with an associated loss of brake and steering power assist. If these conditions were to lead to a crash the airbags may not deploy as expected. Dealers will inspect and replace the ignition lock housing as necessary to correct this concern.
