2010 Cadillac Truck SRX FWD V6-3.0L Technical Service Bulletin # 08-08-44-028A Date: 120411

Audio - Inadvertent Steering Wheel Button Activation

INFORMATION

Bulletin No.: 08-08-44-028A

Date: April 11, 2012

Subject: Information On Inadvertent Steering Wheel Control (SWC) Button Press Causing Radio Anomalies

Models:

2013 and Prior GM Passenger Cars and Trucks

All Vehicles with Steering Wheel Controls

Supercede:

This bulletin is being revised to add model years. Please discard Corporate Bulletin Number 08-08-44-028 (Section 08 - Body and Accessories).

This bulletin is being issued to provide a recommendation for vehicles with a customer concern of the radio station tuning changing by itself,

volume changing by itself, radio changing by itself or radio muting or going silent when driving and turning the steering wheel.

The switches on the right hand side of the steering wheel are easily pressed and may inadvertently be pressed when turning the steering wheel.

These concerns may be affected by the location of the steering wheel controls.

Recommendation

Do Not Replace The Radio

1. Please determine that the switch controls on the steering wheel are functioning correctly.

2. Ask the customer if their hand was in close proximity to the steering wheel controls when the condition happened. Explain to the customer

that bumping the controls would have caused this undesired action. Explain to the customer the proper use and function of the steering wheel
