Recall 10V223000: ECM Software Update

VEHICLE MAKE/MODEL: MODEL YEAR(S):

Cadillac/SRX 2010

MANUFACTURER: General Motors Corp.

MFR'S REPORT DATE: May 24, 2010

NHTSA CAMPAIGN ID NUMBER: 10V223000

NHTSA ACTION NUMBER: N/A

COMPONENT: Engine and Engine Cooling

POTENTIAL NUMBER OF UNITS AFFECTED: 547

SUMMARY:

General Motors is recalling certain model year 2010 Cadillac SRX equipped with a 2.8L V6 engine. If low octane (regular) fuel is used in the

vehicle instead of the required high octane (premium) fuel as stated in the owner manual and on the fuel filler door, the combination of regular fuel

usage and aggressive driving maneuvers may induce pre-ignition. If pre-ignition occurs, you may hear a pinging or knocking sound from the

engine.

CONSEQUENCE:

If the vehicle continues to be driven after the onset of this noise, a connecting rod or piston may break, resulting in engine damage, and perhaps

engine failure, which would disable the vehicle increasing the risk of a crash.

REMEDY:

Dealers will reprogram the engine control module free of charge. The safety recall is expected to begin on or before June 11, 2010. Owners may

contact The Cadillac Customer Assistance Center at 1-866-982-2339 or at The Owner Center at www.gmownercenter.com.

NOTES:

Owners may also contact The National Highway Traffic Safety Administration's Vehicle Safety Hotline at 1-888-327-4236 (TTY
