2004 Porsche 911 carrera problems
The Porsche 911 (pronounced Nine Eleven or in German: Neunelf) is a two-door 2+2 high performance rear-engined sports car introduced in September 1964 by Porsche AG of Stuttgart, Germany. It has a rear-mounted flat-six engine and originally a torsion bar suspension. The car has been continuously enhanced through the years but the basic concept has remained unchanged. The engines were air-cooled until the introduction of the 996 series in 1998.
The 911 has been raced extensively by private and factory teams, in a variety of classes. It is among the most successful competition cars. In the mid-1970s, the naturally aspirated 911 Carrera RSR won world championship races including Targa Florio and the 24 Hours of Daytona. The 911-derived 935 turbo also won the 24 Hours of Le Mans in 1979. Porsche won the World Championship for Makes in 1976, 1977, 1978, and 1979 with 911-derived models.
In a 1999 poll to determine the Car of the Century, the 911 was fifth. It is one of two in the top five that had remained continuously in production (the original Beetle remained in production until 2003). The one millionth example was manufactured in May 2017 and is in the company's permanent collection.

Common 2004 Porsche 911 carrera problems
Based on the information provided in the sources, here is a list of common problems with the Porsche 911 Carrera 2004 based on complaints from owners:
- IMS Bearing Issues:
- The Porsche 996 faced significant issues with the IMS (Intermediate Shaft) bearing, particularly in models produced between 1997 and 2004. The failure of the IMS bearing can lead to catastrophic engine failure, making it a crucial component to address. Upgrading the IMS bearing is highly recommended to prevent such failures.
- Coolant and Oil Mixing:
- Some Porsche 996 engines experienced coolant mixing with oil, leading to a milky brown color in the oil or oil inside the coolant. This issue can be exacerbated by the expansion and contraction of the engine during normal operation, causing leaks or weeping of oil through the engine walls. Unfortunately, once this problem occurs, the only solution is to replace the engine.
- Chain Tensioner Failures:
- Chain tensioner failures have been reported in some M96 motors, resulting in noisy startups that quiet down suddenly. This issue was addressed by Porsche with an updated design in 2000. If owners notice unusual noise during startup, it is advisable to check and replace the chain tensioners to prevent potential problems.
- Suspension Issues:
- The Porsche 911 Carrera 2004 may encounter suspension problems, such as broken springs or leaking PASM (Porsche Active Suspension Management) dampers. Leaking dampers can affect the handling of the vehicle and pose safety risks. Owners have reported hearing loud cracks from broken springs, which can be replaced to maintain consistent handling characteristics.
- Other Maintenance Considerations:
- Regular maintenance is essential for the Porsche 911 Carrera 2004 to prevent common issues and ensure optimal performance. This includes oil changes, filter replacements, and thorough inspections to address any potential wear and tear. Following the recommended maintenance schedule and using quality parts can help in keeping the car in good condition.
By addressing these common problems proactively and ensuring regular maintenance, owners of the Porsche 911 Carrera 2004 can mitigate potential issues and enjoy a reliable driving experience with this iconic sports car.
Is 911 Carrera reliable?
According to motorbiscuit.com, the Porsche 911 is one of the most dependable cars you could own, even more reliable than some traditional options from Honda. It's one of the best choices if you want to purchase a luxury sports car with some history. There are some issues with the Porsche 911, as with any vehicle.
Is Porsche 911 good for daily use?
Space is probably one of the biggest reasons people think the 911 can't be a daily driver. This is a valid concern but for most people, there is enough space for everyday driving. The Porsche 911 is a four-seater, but most 911 drivers agree that the rear seats are best suited for your coat or bag.
How long do Porsche 911 engines last?
A well-maintained Porsche 911 can last 100,000 to 200,000 miles. If you drive around 13,500 miles per year, which is the average annual mileage for most drivers, your 911 can last for 15 years. With meticulous care and less usage, this car can last over 15 years.
What to look for when buying old 911?
Check out the condition of the mechanics: it's always a good idea to check under the hood of a classic car. Be sure to check that the engine, battery, and other parts are clear from obvious damage.
