Recalls, owner-reported complaints, investigations and safety data
Data refreshed
Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

What owners report
Complaints grouped by the component NHTSA recorded
Percentages are of component mentions. A single complaint can name more than one component, so these do not sum to the total complaint count.
Safety recalls
No recalls in our database for this model year
That does not guarantee a specific vehicle is unaffected — recalls are issued against VINs, and new campaigns are announced regularly. Check a VIN on NHTSA.gov.
Safety investigations
NHTSA inquiries naming this vehicle. An investigation is not a finding of a defect.
On April 26, 2013, the Office of Defects Investigation (ODI) opened PE13-009 to investigate 10 complaints alleging incidents of sudden coolant loss while traveling on public roadways in certain model year (MY) 2001 through 2007 Porsche 911 vehicles.The complaints alleged that pipe ends joined by epoxy to certain cooling system components may fail suddenly and separate, resulting in large volumes of coolant leakage.The investigation was opened to assess evidence of a design or manufacturing defect in the coolant pipe fittings and any related safety consequences. In response to ODI?s Information Request letter, Porsche identified a manufacturing quality issue with the supplier?s application of adhesive to coolant pipe fittings that resulted in elevated failure rates in approximately 6,800 early production 997 generation vehicles (MY 2007 and early MY 2008).ODI?s analysis of field data showed that the age-adjusted failure rate for these vehicles was approximately six times greater than MY 2001 through 2005 996 generation vehicles and MY 2008 through 2011 997 generation vehicles built after a process improvement for adhesive application was implemented by the supplier.Most of the leak complaints reviewed by ODI did not appear to involve complete separation of the fittings and many were detected when the vehicle was parked.There were no crashes or injuries reported to be related to the alleged defect in any of the subject vehicles.ODI identified two allegations that coolant leakage resulted in loss of control incidents, but neither involved vehicles affected by the assembly process quality issue.A third loss of control allegation involving a vehicle built during the period affected by the supplier process concern is not counted since ODI was unable to contact the owner to confirm the incident.See the full closing resume in the document file for PE13-009 for additional information about the subject cooling system and ODI?s analysis of field data related to the alleged defect. A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor this issue and reserves the right to take further action if warranted by the circumstances.

Yesterday as I was driving in freeway, my friend was following me from behind, he noticed smoke and coolant leaking making his car's windshield dirty. So we stopped at gas station and noticed good amount of coolant leakage from underneath which make the back of the car and tires big mess. I noticed, before my friend's call, the handling and grip of the car was little off, I didn't know why but then I realized leaking made the tires slippery. Tow the car to my house and just wanted to report this. It seems lot of people complain about this issue when I started reading about it last night.

MY GT3 HAS COOLING PIPE ON THE ENGINE EXTERNAL TO THE BLOCK. I HAVE READ THIS IS A SYSTEMIC ISSUE WITH THE ENGINE USED IN GT3 AND TURBOS (METZGER MOTOR). A FITTING COMES LOOSE DUE TO ADHESIVE FAILURE RESULTING I LOSS OF ALL OR MOST OF THE COOLANT FLUID. THE REPAIR REQUIRES ENGINE REMOVAL AND REPAIR OF THE FITTINGS. THERE IS SOME ISSUE AS TO THE PROPER OR BEST REPAIR APPROACH. WHAT IS KNOW IS THAT THE ADHESIVE FAILURE IS ALMOST SURE TO OCCUR. I HAVE BEEN LUCKY AS I HAVE FEW MILES ON MY VEHICLE AND HAVE NOT YET EXPERIENCED THIS FAILURE, BUT VERY CONCERNED THIS WILL OCCUR AND THE SUDDEN LOSS OF COOLANT FLUID WILL MOST LIKE RESULT IN A SPINOUT OR CRASH. EVEN IF NO ACCIDENT WERE TO RESULT, I AM OUT OF NORMAL WARRANTY, THIS FAILURE WILL SET ME BACK $1500-2000. I HAVE FOLLOWED REPORTS OF THE NUMEROUS FAILURES OF THESE FITTINGS ON 6SPEEDONLINE.COM. AS I HAVE NOT YET HAD A FAILURE, I STILL WANT TO REGISTER MY CONCERN SHOULD THERE BE A NHTSA DIRECTED RECALL TO PORSCHE. *TR

TRAVELING AT A SPEED OF 30 MILES PER HOUR AT A LOW RPM, I HEARD A LOUD GRINDING NOISE UNDERNEATH THE CAR. INITIALLY I THOUGHT ROAD DEBRIS WAS CAUGHT UNDERNEATH THE CAR AND I WAS DRAGGING IT ALONG WHILE DRIVING. I QUICKLY TURNED THE CAR TO THE RIGHT OFF THE ROAD AND TURNED THE MOTOR OFF. UNDERNEATH THE VEHICLE I NOTICED ALL OF THE ENGINE'S OIL SPEWING OUT FROM THE BOTTOM OF THE ENGINE. I CONTACTED MY INSURANCE COMPANY AND ARRANGED FOR A TOW VEHICLE. I THOUGHT AN OBJECT STRUCK THE UNDERCARRIAGE OF MY CAR. THE CAR WAS INSPECTED BY MY INSURANCE COMPANY AND DETERMINED TO BE A COMPLETE ENGINE FAILURE. NO EVIDENCE OF A ROAD HAZARD PERFORATING THE ENGINE WAS SEEN. SINCE I FILED THIS LETTER I HAVE LEARNED THAT MY ENGINE SUFFERED AN INTERMEDIATE SHAFT FAILURE. THIS IS A DEFECT IN THE M96 PORSCHE ENGINES (1999-2009). THIS DEFECT OCCURS IN WATER COOLED PORSCHE ENGINES. PORSCHE MOTOR COMPANY DENIES RESPONSIBILITY IN THESE VEHICLES BUT RECOGNIZES THAT ENGINE FAILURE DO OCCUR. I HAVE ACCURATE RECORDS WITH THE COST OF THE REPAIR. HOW CAN AN AUTOMOBILE COMPANY RECOGNIZE THAT A DEFECT EXISTS BUT WILL NOT ISSUE OR BE RESPONSIBLE FOR REPAIRS? THANK YOU FOR YOUR HELP. UPDATED 09/12/11

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.

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. Older model years have had longer for reports to accumulate.
