2011 Porsche Panamera Engine 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.

THE ENGINE OF MY PORSCHE PANAMERA WENT INTO A TOTAL FAILURE BECAUSE OF FAULTY DESIGN/PARTS BY THE MANUFACTURER (I.E. SCREWS BROKE INSIDE THE CAMSHAFT/BLOCK). AFTER DOING RESEARCH ONLINE, THIS IS A VERY COMMON PROBLEM WITH PORSCHE PANAMERA, EVEN THE SERVICE MANAGER AT THE DEALERSHIP (PORSCHE OF ORLANDO) TOLD ME THIS. DUE TO THIS ISSUE, THE CAR, WHILE MY SON WAS DRIVING, ESSENTIALLY STOPPED WORKING AND QUICKLY DECELERATED FROM 70 MPH TO A COMPLETE STOP IN A MATTER OF SECONDS. LUCKILY, THE SEMI THAT WAS BEHIND HIM MANAGED TO AVOID A COLLISION WHICH, IF SUCH A COLLISION WERE TO HAPPEN, COULD HAVE EASILY KILLED MY SON. PORSCHE ACKNOWLEDGES THAT THIS PROBLEM EXISTS AND A SIMPLE INTERNET SEARCH WILL DISPLAY MULTIPLE COMPLAINTS OF IDENTICAL PROBLEMS WITH THIS VEHICLE'S ENGINE BUT PORSCHE IS NEGLIGENT BY REFUSING TO ISSUE A RECALL ON THE VEHICLES SUSCEPTIBLE TO THIS PROBLEM. NOT ONLY IS THIS A HAZARD, PORSCHE REFUSES TO ISSUE REPARATIONS TO OWNERS AFFECTED BY THIS PROBLEM LEAVING PEOPLE LIKE ME OUT OF WARRANTY AND A CAR AS THE ONLY SOLUTION IS A COMPLETE ENGINE REPLACEMENT WHICH COST MORE THAN THE CAR IS WORTH. EVEN IN OTHER COUNTRIES, NAMELY CHINA, RECALLS HAVE BEEN ISSUED FOR THIS VERY PROBLEM, YET HERE IN THE U.S., THERE HAS BEEN NOTHING. THIS SEEMS TO BE A COMMON ISSUE WITH THIS COMPANY AS VW, THE PARENT COMPANY, WAS RECENTLY SUED FOR LYING ON MECHANICAL STATISTICS (I.E. EMISSION REPORTS). I AM HOPING THAT YOU WILL ASSIST ME IN MAKING A COMPELLING CASE AND ASSURE THAT PORSCHE ANSWERS FOR THEIR NEGLIGENCE AND REFUSAL TO HELP ITS CUSTOMERS. *TR
