Reports submitted to NHTSA, shown in the owner's own words
ON 4/18/2021 I WAS DRIVING MY 1991 PORSCHE C2 ON THE 10 FREEWAY IN MONTEREY PARK, CA WHEN SUDDENLY I HEARD A LOUD BANG SOUND FROM THE ENGINE. I GOT OFF THE FREEWAY AND STOPPED AND FOUND THAT THE ENTIRE ENGINE COOLING FAN HAD COMPLETELY SHEARED OFF AND BROKE APART ALONG WITH THE FAN BELTS. LESS THAN 5 YEARS AGO THE SAME ENGINE COOLING FAN HAD TO BE REPLACED BECAUSE IT BROKE APART. THIS FAN ALSO BROKE APART ABOUT 20 YEARS AGO! THE CURRENT INCIDENT CAUSED DAMAGE TO THE ALTERNATOR AND AIR CONDITIONER COMPRESSOR AND THE BELTS AND SMALL DENTS TO THE BACK LID.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
