Porsche 911 carrera 4s problems
The Porsche 991 is the seventh generation of the Porsche 911 sports car, which was unveiled at the 2011 Frankfurt Motor Show on 15 September as the replacement for the 997. The 991 was an entirely new platform, only the third since the original 911 launched in 1963 (the 996 of 1999 was the second new platform). Production of the 991 generation ended on December 20, 2019, with 233,540 units produced.
Design
Compared to the 997, the 991 is slightly larger, with the wheelbase increased by 100 mm (3.9 in) to 2,450 mm (96.5 in), and the overall length up by 70 mm (2.8 in) to 4,490 mm (176.8 in). A new transaxle was developed so that the rear wheels could be moved 76 mm (3 in) backward in relation to the position of the engine, which significantly improves the weight distribution and cornering performance of the car.
Due to the use of high-strength steel, aluminium and some composites, the weight was reduced to 1,380 kg (3,042 lb) for the manual Carrera, rising to 1,605 kg (3,538 lb) for the all wheel drive Turbo model if equipped with the PDK transmission (Porsche Doppelkupplung). PDK is available as an option for all 911 Carrera and 911 Turbo (991.1 Non S) models as a 7-speed transmission, featuring manual and automatic modes. Gears 1 to 6 have a sports ratio and top speed is reached in 6th gear. 7th gear has a long ratio and helps to reduce fuel consumption by keeping engine revs low. The PDK is essentially two gearboxes merged into a single unit and thus requires two clutches. For all 991 models, the PDK is produced by ZF Friedrichshafen. The auto start/stop function is standard on all variants of the 911 Carrera.

Common Porsche 911 carrera 4s problems
The Porsche 911 Carrera 4S is a highly regarded sports car, but like any vehicle, it can have certain issues that owners may encounter. Here are some of the most common problems based on complaints from owners:
- Excessive oil consumption: Another common issue with the 2009 model is excessive oil consumption, which may require frequent top-ups or more extensive engine repairs.
- Leaking hoses: Leaking hoses have also been reported by owners of the 2009 Porsche 911 Carrera 4S, which can lead to various engine problems if not addressed promptly.
- Internal leak at the oil separator: According to RepairPal, this is the most common Porsche 911 problem reported by real owners. It can cause rapid oil consumption, smoke, and fuel trim problems, requiring replacement of the oil separator by a mechanic.
- Coolant loss and engine overheating: This issue is the second-most frequent problem reported by Porsche 911 owners. It is caused by a small leak in the coolant reservoir, which can lead to engine damage if not resolved promptly.
- Oil leak at the rear main seal/intermediate support cover o-ring: This issue can usually be fixed via a revised engine seal, but it requires precise diagnosis to confirm the dimensional accuracy.
- Bad service history: A poor service history can be a concern when buying a used Porsche 911 Carrera 4S, as it may indicate neglected maintenance or hidden issues.
- Cracked coil packs: Misfiring engines can be caused by cracked coil packs, which are relatively inexpensive to replace.
- Faulty alternator cables: Early Porsche 997 models, including the Carrera 4S, can suffer from decreased battery life and run-time due to faulty alternator cables. Replacing them with upgraded cables is a straightforward job, but routing can be tricky.
- Damaged radiators: Coolant radiators and aircon condensers in the nose of the 997 are prone to leakage, which can be a common sight in older models. Always check the radiator's condition with the previous owner or take it to a specialist for inspection.
It is important to note that not all Porsche 911 Carrera 4S models will experience these issues, and many can be resolved with proper maintenance and repairs. However, being aware of these common problems can help potential buyers make informed decisions when considering a purchase.
