- [ITB12026F](/bulletins/10192775.md), 2021-05-10, Service bulletin: SERVICE BRAKES, HYDRAULIC. IF YOU CONFIRM: An APPLIED VEHICLE has the MIL ON with DTC P0106 \(Manifold Absolute Pressure \[MAP\] circuit range/performance\) stored in the ECM. ACTION: 1. Refer to step 6 in the SERVICE PROCEDURE to confirm this bulletin applies to the vehicle you are working on. 2. If this bulletin applies, reprogram the ECM with CONSULT\-III plus ONLY. See this bulletin for further detail.
- [ITB15018A](/bulletins/10192763.md), 2021-05-10, Service bulletin: SERVICE BRAKES, HYDRAULIC. IF YOU CONFIRM: "Brake Judder" during braking, especially when braking at highway speeds. Symptoms of "brake judder": \- steering wheel shake \- body vibration \- brake pedal pulsation IMPORTANT NOTES: If any symptom above occurs when cruising or coasting \(not braking\), it is not "Brake Judder" and may be tire/wheel related. DO NOT CONFUSE "Brake Judder" with the rapid consistent\-speed pedal pulsation that may be felt and only occurs when ABS is activated during hard braking or on slippery road surfaces. ACTION: 1. Inspect the front brake rotors to determine if "machining" \("turning"\) is possible or if replacement is necessary. 2. Replace both pad pins in both front 4\-piston calipers \(see PARTS INFORMATION\). 3. Replace the front brake pads \(see PARTS INFORMATION\). See this bulletin for further detail.
- [ITB14059A](/bulletins/10192666.md), 2021-05-10, Service bulletin: VEHICLE SPEED CONTROL; PARKING BRAKE; SEAT BELTS. IF YOU CONFIRM All "hands free" functions of the Intelligent Key \(I\-Key\) do not work. For example, the doors will not lock or unlock when pressing either front door request switch. NOTE: \- The issue of all I\-Key "hands free" functions not working may occur intermittently or all the time. \- The message "No Key Detected" or similar may show on the Vehicle Information Display \(located in the combination meter\). \- All I\-Key remote button functions \(door lock/unlock, etc.\) WILL work normally when all I\-Key "hands free" functions are NOT working. ACTION 1. Inspect the I\-Key?s battery on its negative contact side. 2. If excessive scratching is found, replace the battery. 3. Verify all I\-Key functions \(both "hands free" and remote\) work properly after battery replacement. NOTE: Do NOT replace the BCM, I\-Key, or other parts for the issue described under IF YOU CONFIRM, if it should occur. See this bulletin for further detail.
