Involved vehicles are marked “open” on the Investigate Vehicle History screen in GM Global Warranty Management system. This site should always be checked to confirm vehicle involvement prior to beginning any required inspections and/or repairs.

Condition

Certain 2017 model year Cadillac XT5 and GMC Acadia vehicles may have a brake pedal position sensor (BPPS) flag bracket which allows too much rotation, causing the BPPS sensor to indicate the brake pedal is applied. This could cause the brake lamps to stay on, which could impair the brake lamps ability to indicate the intention of the driver to stop or slow the vehicle, and/or could drain the battery. In addition, this condition may cause the cruise control to be inoperative.

Correction

Inspect and, if necessary, replace the pedal assembly.

Parts Information

There is a small percentage of vehicles anticipated that will need this fix. Due to limited initial parts availability, dealers are encouraged not to order recall parts for use as shelf stock.

Reminder: Parts may be removed from Retail Inventory Management (RIM) management. Dealers should review the affected parts to confirm RIM managed status. Parts may have quantity limiters in effect.

Service Procedure

1. Position the front driver seat in the rear most position to gain access to the brake pedal position sensor (BPPS) switch activation bracket (1).

2. Ensure all three BPPS switch activation bracket plastic tabs (1) are secured over the pedal arm.
   • If all three BPPS switch activation bracket plastic tabs are secured over the pedal arm, proceed to the next step.
   • If any of the BPPS switch activation bracket plastic tabs are NOT secured over the pedal arm, secure the BPPS switch activation bracket tabs over the pedal arm and proceed to the next step.

3. Using your fingers, rotate the BPPS switch activation bracket back and forth (2) to determine if there is any movement at the base of the bracket and bracket shaft (3).

Note: If the brake lights remain on after the BPPS inspection, replace the brake and accelerator pedal bracket. Refer to Brake and Accelerator Pedal Assembly Replacement in SI.

• If there is 1 mm (3/64 in) or less of movement in any direction or less than 2 mm (5/64 in) of movement total in both directions and the brake lights do NOT remain on after attempting to rotate the BPPS switch activation bracket, no further action is required.
• If there is more than 1 mm (3/64 in) of movement in any direction or over 2 mm (5/64 in) movement total in both directions and the brake lights remain on after attempting to rotate the BPPS switch activation bracket, replace the brake and accelerator pedal assembly. Refer to Brake and Accelerator Pedal Assembly Replacement in SI.
