Vehicles Affected: About 16,932 model-year 2011 Cadillac CTS sedans equipped with all-wheel drive
The Problem: On some vehicles, a gasket leak where the constant velocity joint meets the rear propeller shaft may cause the rear propeller shaft to separate or become loose, making contact with the vehicle floor above and causing the rollover sensor to deploy the roof rail air bags. GM said it is aware of 15 unintended deployments, but that it was uncertain whether injuries had occurred.
The Fix: GM will notify owners and dealers will make the necessary repairs for free.
What Owners Should Do: GM has not yet provided an owner notification schedule. Owners can call Cadillac at 800-333-4223 for more info.
