Subject:

Intermittent Unwanted Trunk Opening While Vehicle is Parked

Models:

2010-2013 Buick LaCrosse
2011-2013 Buick Regal
2012-2013 Buick Verano
2011-2013 Chevrolet Cruze
2012-2013 Chevrolet Sonic (4 Door Sedan Only)
2013 Chevrolet Malibu

Condition/Concern
Some customers may comment on unwanted opening of the trunk without pressing any of the release buttons while the vehicle is parked. Although the trunk is
unlatched while parked, the owner may not observe the trunk open until they begin to drive the vehicle. This may also be accompanied with a “Trunk Open”
message in the DIC.
This condition may be caused by the trunk release button on the remote transmitter being pressed inadvertently while the transmitter is in their pocket or purse.

Recommendation/Instructions
Replace the KR95B Rear Compartment Lid Unlatch Relay with a “Two Shot Relay”, GM P/N 19119267, using the applicable procedure below. When installed,
the remote transmitter (key fob) trunk release button, the exterior rear compartment lid release switch (touch pad) or the interior rear compartment lid release
switch must be pressed twice within three seconds to release the trunk.

For LaCrosse, Regal (2011 Germany Built (RPO RUE)), Verano, Cruze and Malibu
Remove the KR95B Rear Compartment Lid Unlatch Relay located in the X51A Instrument Panel Fuse Block and install the “Two Shot Relay.”

For Regal (2011 Oshawa Built (RPO OSH), 2012-2013) and Sonic
The rear compartment lid unlatch relay is part of the printed circuit board in the relay/fuse block and not serviceable separately. Installation of an external relay
circuit to bypass the feed to the trunk release control will be required. Install the “Two Shot Relay” adjacent to the BCM and attach a tag to the relay and mark
with “Two Shot Trunk Relay per Bulletin PI0924.” For future diagnosis for an inoperative trunk release, this relay installation will be identified before a BCM is
replaced.

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.
