Manufacturer Communication Number: PIP-5366-A
Summary
THIS PRELIMINARY INFORMATION COMMUNICATION PROVIDES INFORMATION TO THE TECHNICIAN THAT SOME OWNERS MAY NOTICE AT ROUGHLY 3/4 OF THE WAY THROUGH THE ACCELERATOR PEDAL TRAVEL THERE IS A CLICK FELT IN THE PEDAL ALSO THE PEDAL GETS HARDER TO PUSH. PLEASE COMMUNICATE TO THE CUSTOMER THIS CONDITION IS A NORMAL OPERATING CHARACTERISTIC OF THEIR VEHICLE. THE ACCELERATOR PEDAL DESIGN HAS CHANGED FOR VEHICLES EQUIPPED WITH THE 8-SPEED AUTOMATIC TRANSMISSION REGULAR PRODUCTION OPTION CODE MRC.
Condition/Concern
Some owners may notice at roughly 3/4 of the way through the accelerator pedal travel there is a detent/click felt in the pedal with increased resistance.
The accelerator pedal design has changed for vehicles equipped with the 8-speed automatic transmission (RPO MRC).
The new accelerator pedal design has a built-in detent position that can be noticed at roughly 3/4 pedal travel.
The detent provides feedback to the operator to minimize transmission downshifting, allowing for improved fuel economy, smoother operation, etc.
Pressing up to the detent will allow a more relaxed acceleration rate.
When pressing through the detent, the transmission will downshift aggressively allowing for an increased acceleration rate.
Recommendation/Instructions
Important: DO NOT replace any parts for this condition.
This is a normal operating characteristic of the vehicle and no repair attempts should be performed.
Customer Information
Please communicate to the customer this condition is a normal operating characteristic of their vehicle. It will not impact the designed performance or reliability of the vehicle. Please share this information with the customer, including a copy of this message.

GM bulletins are intended for use by professional technicians, NOT a “do-it-yourselfer”. They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information. WE SUPPORT VOLUNTARY TECHNICIAN CERTIFICATION 1
