The 991 generation of the Porsche 911 was produced between 2011 and 2019, and was one of the brand’s best selling models in recent years. This iconic German sports car is one that has been highly regarded by enthusiasts and the automotive press alike, with many praising its sporty performance and luxurious interior, all while maintaining the 911’s classic looks.
However, like any vehicle, this generation of Porsche 911 was not without its issues. Some common problems reported by owners of 2011-2019 Porsche 911 models include:
- 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. Not sure? Let us diagnose.
Cooling System Issues:
- 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.
- Water Pump: Some 991 owners have reported water pump failure, which can lead to overheating and potential 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: Aggressive alignment settings, especially on cars with sport suspension, can result in uneven tire wear. Regular alignment checks can help mitigate this problem.
- Power Steering Issues: Some owners have experienced power steering failure or loss of steering assist, which can be caused by a failing electric power steering motor or other electrical issues.
Electrical and Software Issues:
- Mechanical Valve Failure: Some 991 owners have reported failures attributed to mechanical flaps, such as exhaust flaps, air vent flaps, and others. This is often caused by a failing Change Over Valve (COV), which controls a number of automated flaps and valves throughout the vehicle.
- Infotainment Glitches: Some owners have reported problems with the infotainment system, such as freezing, lagging, or connectivity issues. Updates to the system software may resolve these problems.
- Battery Drain: Some 991 models have been known to experience battery drain, which 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:
- Stone Chips: 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.
Keep in mind that 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.
