After recalling all of the 785 2014 Porsche 911 GT3 sports cars last month, the German automaker recently announced that it will be replacing all the engines of the said units. Porsche spokesman Nick Twork confirmed the plans for engine replacement on Monday.
On February 20th, Porsche said it was recalling all units of the current model year 911 GT3s sold across the globe. The recall was due to a fire risk, though the carmaker had not yet determined the reason for the engine fires at that time. The recall was issued after Porsche received reports of two vehicles in Europe catching fire because of engine damage. One incident occurred in Italy, while the other happened in Switzerland. No one was hurt in both incidents.
The Stuttgart, Germany-based company then asked the owners of the affected vehicles to park their cars until they can be inspected for potential engine problems. The automaker offered to pick up the vehicles and bring them to the Porsche Center as soon as possible, since they do not recommend the owners driving the vehicles.
Consequently, Porsche also ordered dealers to temporarily halt the sale of the sports cars.
Less than a month later, Porsche says that they will replace the engines in every 2014 911 GT3 built so far. Of the total 785 units, about 400 were delivered in the United States. According to the automaker, half of that number has already been sold. Porsche has asked owners to stop driving the cars until the engines are replaced.
The company will soon send a formal recall notice to the National Highway Traffic Safety Administration (NHTSA).
In a letter posted on an owner forum, Porsche said that their investigation regarding the engine fires is finished and that they have determined the problem. The letter was from Porsche Cars North America Aftersales Vice President Tim Quinn.
The cause of the engine damage was identified in the letter as a ‘loosened piston screw connection.’ Twork told Automobile Magazine that the problem was mainly the connecting-rod fasteners in the engine. If these fasteners become loose, the connecting rod will detach from the crankshaft, eventually resulting in the fires reported in both Italy and Switzerland. He said that the company chose to replace the engines rather than repair or rebuild the vehicle.
As indicated in the letter, Porsche seeks to fix the engine problem with ‘an optimized screw connection.’ Since the automaker is still in the process of testing the improved piston rod screw connections, it cannot provide customers a specific timeline for replacement at this point.
The GT3 is considered as the sportiest of all 16 Porsche 911 variants available in the United States. The car, which is often driven on race tracks, come with a 3.8-liter flat-six engine equipped with a 9000-rpm redline and rated for 469-hp. The high-performing sports car, which has a seven-speed PDK dual-clutch automatic transmission, also features 20-inch center locking wheels, an adjustable carbon-fiber rear wing and a three-part front splitter.
In the United States, the price of the two-seat sports car starts at $131,395, including destination fee.
