What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2003 Porsche 911 Turbo, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
WHILE DRIVING HOME FROM WORK IN DECEMBER 2015, ON A LOCAL ROAD NEAR MY HOME, THE ENGINE BEGAN EMITTING A LARGE STEAM CLOUD BEHIND THE VEHICLE AND THE COOLANT LEVEL LIGHT APPEARED. I PULLED OVER AND THERE WAS A MAJOR COOLANT LEAK BEHIND THE CAR. I HAD THE CAR TAKEN TO A SHOP, AND THEY IDENTIFIED THE ISSUES AS ONE OF THE COOLANT PIPES HAD SEPARATED FROM THE ENGINE AND DUMPED ALL OF THE COOLANT ON THE ROAD. IN THE ATTACHED IMAGE YOU CAN SEE THE SEPARATED COOLANT PIPE FROM THE ENGINE TOWARDS THE BACK OF THE PICTURE. GIVEN THE COST OF REPAIR, I HAD TO WAIT UNTIL SUMMER OF 2016 TO HAVE THE REPAIR COMPLETED. *TR
I WAS DRIVING ON THE PUTNAM PARK ROAD COURSE TRACK ON 9/12/15, AND ONE OF MY COOLANT FITTINGS BROKE LOOSE FROM THE DEFECTIVE PORSCHE ADHESIVE. IT SPEWED COOLANT ALL OVER THE TRACK, CREATING A VERY DANGEROUS SITUATION CAUSING OTHER DRIVERS TO LOSE CONTROL. I HAD A PORSCHE DEALER REMEDY THE SITUATION BY PINNING THE FITTINGS AND APPLYING NEW ADHESIVE.
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
I WAS DRIVING MY VEHICLE DOWN THE HIGHWAY WHILE ACCELERATING WHEN I FELT THE CAR SQUIRM AND NOTICED A LARGE CLOUD OF SMOKE BILLOWING FROM THE REAR OF THE VEHICLE. I PULLED OVER AND IDENTIFIED THE ISSUE AS A CATASTROPHIC COOLANT LEAK FROM THE ENGINE AREA (REAR) OF THE VEHICLE. I HAD THE VEHICLE TRANSPORTED HOME AND THEN TO A REPAIR SHOP WHERE THEY IDENTIFIED THE PROBLEM AS A COOLANT LINE THAT BECAME SEPARATED FROM THE ENGINE BLOCK. IT WAS EXPLAINED TO ME THAT PORSCHE, FROM THE FACTORY, USED AN ADHESIVE LIKE MATERIAL TO MATE THE CONNECTORS OF THE COOLANT LINES AND ENGINE AND AFTER USAGE THEY WILL COME APART CAUSING COOLANT TO BE HEMORRHAGED ONTO THE ENGINE AND POTENTIALLY WHEELS/TIRES CAUSING FOR VERY DANGEROUS ROAD CONDITIONS. DURING THE INCIDENT I ALMOST LOST CONTROL OF MY VEHICLE DUE TO THE COOLANT CONTACTING THE TIRES WHICH WOULD NOT HAVE OTHERWISE HAPPENED HAD PORSCHE NOT MANUFACTURED THEIR VEHICLES IN THE AFOREMENTIONED WAY. I AS WELL AS OTHERS ON THE ROAD WERE PUT IN A VERY DANGEROUS SITUATION BECAUSE OF THIS MANUFACTURING ISSUE. *TR
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
