PRELIMINARY INFORMATION
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.
1. Label the four leads of connector, P/N 12126045 as indicated below.
2. Connect the connector to the new relay, P/N 19119267.
3. Locate circuit 6188 (trunk release control) at the BCM following service information. Cut the wire and splice the
BCM and relay side of the circuit as shown below.
4. Connect wire fused, unswitched power and ground as shown below.
