Chevrolet Suburban 2500 ProblemsPower Brake Units May Leak Fluid From Hydro-Boost Unit
Power brake systems using "hydro-boost" may leak power steering fluid from the hydro-boost unit located behind the brake master cylinder. Replacement of the hydro-boost unit is the common repair to correct this concern.
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.
The 4WD transfer case encoder motor position sensor or the selector switch may fail causing the service 4WD message to be displayed. Fault code(s) stored in the transfer case control module will be of assistance in determining the exact fault causing the message to be displayed.

Chevrolet Suburban 2500 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.
The chassis electrical module can short due to internal contamination. This can result in the vehicle stalling. Dealers will replace the chassis electronic module free of charge to resolve the concern.
All late model vehicles are equipped with a "Shift interlock" system that prevents vehicles with and automatic transmission from being shifted out of the Park position under certain conditions. Some of these vehicles are being recalled because they may have been assembled with a broken park lock cable or a malformed steering column lock actuator gear. Failure of these components can allow the shifter to be moved out of the Park position with the ignition key removed or in the off position. This can cause the vehicle to roll away unexpectedly increasing the risk of injury or a crash. Dealers will inspect the recalled vehicles and replace the steering column as necessary.
