This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2011 Buick LaCrosse
No elevated drivetrain pattern for this model year. That describes the model, not the car in front of you.
Get an independent pre-purchase inspection from a mechanic you choose.
4 recall campaigns on this model year. Whether a specific car still has one open depends on the VIN; the report checks that.
Ask for service records. A engine already replaced under warranty is a different car from one that was not.
Have the VIN?Paste it and get the full report for that car. First report free, then a 30-day pass covers a whole car search.
Experimental model-level information. This is not a vehicle inspection, vehicle-history

of any individual vehicle.
