2015 Porsche 911 problems

Common 2015 Porsche 911 problems

The Porsche 911 Carrera, produced in 2015, is a highly regarded sports car known for its design, acceleration, handling, and technological sophistication. However, like any vehicle, it has its share of common problems reported by real owners.

• Internal leak at the oil separator: This issue can cause rapid oil consumption, smoke, and fuel trim problems, resulting in corresponding fault codes. Rectifying this problem typically requires the replacement of the oil separator by a mechanic, along with fixing any resulting issues.

• Coolant loss and engine overheating: This problem is caused by a small leak in the coolant reservoir, which can result in engine damage if not resolved promptly. It is necessary to ensure the longevity and optimal performance of the engine by resolving the coolant loss and resulting overheating, including following the required coolant fill procedure when refilling the cooling system.
• Oil leak at rear main seal/intermediate support cover o-ring: This issue can usually be fixed via a revised engine seal. A technician must closely look at the area from the crankshaft to the engine block with a precise diagnosis to confirm the dimensional accuracy.

• Transmission issues with PDK transmission: The 991 uses Porsche’s PDK dual-clutch transmission, which can occasionally experience issues with rough shifting or hesitation. Software updates or a transmission service may resolve these issues.

• Cooling system issues with the radiator: Due to the design of the engine radiators, which are located at the front of the car, they can be prone to clogging with road debris. Decreased air flow due to debris can adversely affect the cooling system, which can lead to engine damage. Regularly inspecting the cooling system and replacing the water pump when necessary can prevent these issues.

• Suspension and steering issues: Uneven tire wear can result from aggressive alignment settings, especially on cars with sport suspension. Regular alignment checks can help mitigate this problem. Power steering failure or loss of steering assist can be caused by a failing electric power steering motor or other electrical issues.

• Electrical and software issues: Mechanical valve failure can be caused by a failing Change Over Valve (COV), which controls a number of automated flaps and valves throughout the vehicle. Infotainment glitches, such as freezing, lagging, or connectivity issues, can be resolved by updates to the system software. Battery drain can result in a dead battery after extended periods of inactivity. Installing a battery maintainer when the vehicle is not in use can help prevent this issue.

• Body and paint issues: The 991 has wide rear fenders, which can make it more susceptible to stone chips on the paint. Protective film or ceramic coatings can help prevent damage to the paint.

These issues are not necessarily widespread and can vary from one vehicle to another. Regular maintenance such as oil and filter changes, inspections, and addressing issues as soon as they arise can help ensure the longevity and reliability of your 2011-2019 Porsche 911.
