NHTSA lists 2 recall campaigns for the 1991 Geo Storm. Recalls are free to have fixed at a franchised dealer regardless of who owns the car now, but only if they were never done, so check the VIN of the specific car rather than trusting the model.
THE STEERING WHEEL CENTER HUB CAN FRACTURE DURING CERTAIN FRONTAL AND NEAR FRONTAL VEHICLE COLLISIONS.
Risk: FRACTURING OF THE STEERING WHEEL HUB CAN DECREASE THEDRIVER'S CONTROL OF THE VEHICLE AND COULD REDUCE THE CRASH PROTECTION OF THESTEERING SYSTEM AND THE DRIVER'S SIDE AIR BAG.
Fix: A STEERING WHEEL REINFORCEMENT PLATE AND NUT WILL BE ADDED TO THE STEERING WHEEL HUB.
THE FRONT SAFETY BELT BUCKLE RELEASE BUTTONS CAN BREAK. THESE RED PLASTIC RELEASE BUTTONS ARE MARKED "PRESS." IF A BUTTON BREAKS, PIECES CAN FALL INTO THE BUCKLE ASSEMBLY CAUSING THE BUCKLE TO OPERATE IMPROPERLY.
Risk: THE SAFETY BELTS WOULD NOT PROVIDE ADEQUATE PROTECTION TO AN OCCUPANT IN A VEHICLE CRASH.
Fix: OWNERS SHOULD PROMPTLY CHECK THE CONDITION AND OPERATION OF BOTH FRONT SAFETY BELT BUCKLES AND CAREFULLY INSPECT THE RED RELEASE BUTTON FOR ANY BREAKS OR CRACKS. THEY SHOULD ENSURE THAT BOTH BUCKLES A

What stands behind each score for this car:
Owners have filed 98 complaints with NHTSA for this model-year, and engine and engine cooling is the most reported area with 18 of them (18%). There are 2 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 84/100 (excellent) from NHTSA recall campaigns and complaint density. That figure is a raw complaint count, not yet adjusted for sales volume, so a high-volume model scores worse than it deserves.
AVOIR scores its longevity 79/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 1991 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: worth a look, because a solid ownership case with specific caveats below. Its overall ownership score is 73/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
