2011 Porsche Panamera Problems

I am reporting an issue with the AH08 recall (NHTSA Campaign 17V368) for my 2011 Porsche Panamera 4S. I experienced the failure on December 27, 2024, while driving on the highway. I scheduled repair at Porsche Greensboro (Foreign Cars Italia) for Dec 31, 2024, but they kept my vehicle for 33 days without completing any recall work. They then advised me to contact another dealer. I arranged to have the vehicle towed to Porsche Southpoint in Durham, NC, for a February 3, 2025 appointment. As of June 2025, none of the recall repairs have been performed, and the dealer is requesting $12,000 to disassemble the engine for damage stemming from the AH08 issue—work that should be covered under the recall. I have not received any response from the dealership despite repeated requests. I am requesting NHTSA’s assistance in enforcing compliance with the recall requirement and investigating this prolonged failure to perform mandatory safety repairs.

On [XXX], I experienced the failure associated with the AH08 recall while driving on the highway. I promptly scheduled an appointment at Porsche Greensboro (Foreign Cars Italia) for December 31, 2024, at 8:00 AM (Confirmation Code: [XXX]) to address recalls AH08, AKA7, AKB1, and ANB4. Despite keeping my vehicle for 30 days, Porsche Greensboro did not complete any of the recall services and ultimately informed me that they could not perform the work in a timely manner, advising me to contact another dealership. Following this, I scheduled an appointment at Porsche Southpoint for February 3, 2025, at 9:20 AM (Confirmation Code: [XXX]), and Porsche Greensboro arranged to have the vehicle towed there. However, as of today, Porsche Southpoint has not completed the recall repairs and is requesting $12,000 (50% upfront) for engine disassembly related to failures stemming from the AH08 recall. This is deeply concerning, as recall repairs should be addressed promptly and at no cost to the vehicle owner. To date, my vehicle has been out of service for nearly six months with no resolution. I respectfully request your immediate assistance to ensure that the recall repairs are completed without further delay or financial burden to me, in accordance with NHTSA and Porsche’s recall obligations. I have included correspondence with both Porsche Greensboro and Porsche Southpoint for your review. I appreciate your attention to this matter and look forward to a prompt and satisfactory resolution. I can be reached at [XXX] or [XXX] .

Due to a problem with my car engine, the car would not accelerate and would move slowly despite pressing on the pedal. The car screen indicated that it was PCM problem (the gas would not come up) and it was a reduced engine problem. The car not accelerating despite pressing the pedal can pose serious safety problems. I have not taken the car to a dealer to repair yet.

My 2011 Porsche Panamera 4 has water coming through the AC vents. I noticed that the passenger rugs are wet and possibly shorting out my electrical modules.

THE AC/HEATER BLOWER WAS BLOWING WEAK MAKING A SCREECHING NOISE AND NOT BLOWING WELL. PORSCHE CHECKERED IT OUT AND GENERATED A REPORT STATING I NEEDED A NEW BLOWER. AFTER OBTAINING MY CAR BACK FROM THE DEALER WATER WAS LEAKING INSIDE OF MY CAR ( DOES SO WHILE STATIONARY AND DRIVING, ON RAINY DAYS OR WHEN SNOW HAS MELTED ) UNDER THE DASHBOARD. THE BLOWER STOPPED WORKING COMPLETELY. THE REPORT FROM PORSCHE DID NOT STATE ANY LEAKS WERE FOUND. A FORMER PORSCHE MECHANIC INSPECTED THE BLOWER AND FOUND WATER ENTERING THE A/C BLOWER CONTROL UNIT, CAUSING AN ELECTRICAL SHORT CIRCUIT IN BOTH THE BLOWER AND RESISTOR, AND ALSO OBSERVED THE EXTENT OF THE LEAK IN OTHER AREAS OF THE VEHICLE. THE BELOW DAY IS AN APPROXIMATE DAY IN JUNE WHICH IT OCCURRED. ALSO, THE HORN JUST STOPPED WORKING.

THE CAM SHAFT ADJUSTER BOLTS WERE BROKEN AND ARE TEARING APART WITH IN THE ENGINE AND CAUSING THE CAR TO STOP AND NOT START BACK AGAIN, THIS IS ALSO GIVING THE CHECK ENGINE LIGHT, START STOP MODE DEACTIVATED, PSM FAILURE ERRORS, THERE IS A RECALL IN CHINA FROM PORSCHE ABOUT THE SAME ERRORS AND SAME YEAR MODELS

EARLIER THIS YEAR, I WAS DRIVING APPROXIMATELY AT 55 MPH, MY 2011 PORSCHE PANAMERA'S ENGINE LOST POWER AND POWER STEERING,. ELECTRONIC SYSTEM SEEMED TO HAVE POWER, BATTERY WAS NOT DEAD BUT ENGINE WAS DEAD RESULTING IN LOSS OF POWER STEERING AND BRAKES. A SIMILAR PROBLEM WAS ALSO REPORTED BY NUMEROUS DRIVERS WITHIN A THREE YEAR PERIOD ON THIS MODEL CAR (WEB SEARCH). WHEN I ASKED IF PORSCHE WAS AWARE OF A SIMILAR ISSUE, PORSCHE REFUSED TO PROVIDE AN ANSWER.

Every time I drive the vehicle for any distance or speed when I park I can smell fuel. The odor is very strong when I park in the garage. The Odor will last a few hours then go away. But if I have not drove the vehicle that day no odor will be present. It Is smelled back by the gas cap leading me to believe it’s ether the fuel hose receiver or the fuel pump that after investigation have found out the fuel pump is under the back seat on the passenger side. But it is important to note there is never a fuel smell inside the vehicle.

BOTH REAR TIRES, PIRELLI PZERO 275/45ZR18, WERE SEVERELY WORN AT 7430 MILES. THEY WERE REPLACED BY THE DEALER AT MY EXPENSE OF APPROXIMATELY $950.00. I AM A VERY CONSCIENTIOUS DRIVER AND CHECK THE TIRE PRESSURES DAILY. I BELIEVE THIS IS A POTENTIAL SAFETY ISSUE, SINCE YOU WOULD NOT EXPECT TIRES TO BE ON THE VERGE OF BLOWING OUT WITH JUST 7,400 MILES. I HAVE THE TIRES IN MY POSSESSION. *TR

I was informed by a mechanic that when the passenger seat is adjusted to a low position, it causes the seat to damage the airbag control module, thereby causing the airbag to be disabled.

VEHICLE HAS A PUSH BUTTON TO CLOSE TRUNK (HATCH). THE HATCH IS SUPPOSED TO HAVE A SAFETY MECHANISM TO PREVENT ITEMS FROM BEING CRUSHED ON CLOSING. A PIECE OF LUGGAGE WAS BETWEEN THE LATCH AND THE TOP OF THE HATCH AND, ON CLOSING, BECAME WEDGED TO THE POINT THAT THE ONLY WAY TO OPEN THE HATCH WAS TO CUT THROUGH THE CAR FROM THE INSIDE (REAR SEATS FALL DOWN) TO ACCESS THE LATCH MECHANISM. IF A THE HATCH DOES NOT AUTOMATICALLY RETRACT WITH A LUGGAGE STRAP (WHAT ELSE DOES ONE MUST OFTEN PUT IN THE TRUNK OF A CAR OTHER THAN LUGGAGE), SEEMS LIKELY THAT THE HAND OF A SMALL CHILD COULD LIKEWISE BE CRUSHED BY THE AUTOMATIC LATCHING MECHANISM. *TR
