2003 Porsche 911 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 2003 Porsche 911 problems
The Porsche 911, particularly the 2003 model, is known for several common problems that owners have reported over the years. Here are some of the most frequent issues and their likely resolutions:
- Ignition Coils Failure: The ignition coils on the M96 and M97 engines of the Porsche 911 are susceptible to failure, which can lead to worn spark plugs, cracks in ignition coils, and oil leaking past the spark plug tube seals. These issues can cause the check engine light to illuminate and may require replacement of the ignition coils or spark plugs.
- Interior Electrical Misbehavior: Some 911 models, particularly those with cabriolet tops, may exhibit strange and seemingly random electrical misbehavior of interior systems, such as interior lights staying on, airbag faults, or seat malfunctions. This problem can often be traced back to a single control module located under the driver's seat, which can become water damaged due to its proximity to the driver door and window.
- Ignition Switch Failure: The ignition switch in older 911 models, including the 2003 model, can fail, causing the key to become stuck in the ignition or preventing the car from starting. This issue is typically caused by a failure in the ignition switch mechanism and can be resolved by replacing the electrical or mechanical portion of the switch.
- Rear Spoiler Malfunction: The rear spoiler on the Porsche 911, which raises and lowers based on speed, can malfunction, leading to a lopsided spoiler or a "failure spoiler control" warning on the dashboard. This issue can be expensive to fix, as it may require replacing the slave cylinder or other components of the spoiler control system.
It's important to note that these issues are not exclusive to the 2003 model and can be found in other model years as well. Regular maintenance, inspections, and timely repairs can help prevent these problems or minimize their impact.
Is a Porsche 911 expensive to maintain?
Yes, Porsches are expensive to maintain compared to most automakers' vehicles. Estimates from RepairPal show maintaining a Porsche costs an average of about 83% more than the industry average.
Are old Porsche 911 reliable?
Spare parts are still easy to find but expensive when purchased from dealers. Properly maintained, early 911s can be reliable daily drivers that are bound to turn more heads than their modern counterparts, particularly in loud period colors.
What years did Porsche have engine problems?
The Porsche IMS bearing problem years are from 1997 to 2005, with the M96 or M97 engine in these models being particularly susceptible. The single-row bearing used from model year 2000 through 2005 is of the greatest concern. However, any IMS bearing can and will fail if not replaced as part of regular maintenance.
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.

According to my research, the IMS bearing problem only affects 4% of the models produced. However, if the IMS bearing fails, it can be a very expensive repair or even require a replacement motor. On the bright side, once the car is repaired, it runs like a Porsche! It has great acceleration, with anything above 4000 RPM bringing a smile to your face. The handling is spot on, as expected from any Porsche auto. I'm excited to do some hot laps at the track this season, as it's the only place you can really push the car to its limits! I've even had the pleasure of driving it on two different tracks, High Plains Raceway in Byers, Colo. and Aspen Motor Sports Park in Aspen, Colo. The car ran strong and did not disappoint. It's also very comfortable for long trips, and the mountain road curves were made for this car!

The performance and handling of the Porsche 911 are truly exceptional! It delivers on the promise of outstanding performance, comfort, and reliability. This is a true driver's car; not Spartan, but neither is it burdened with clutter and unnecessary bells and whistles. What is most remarkable is that such a capable sports car can be so civilized!

That sounds like an amazing experience! The handling is so superior and it must be so exciting to drive so fast.

This is the definition of perfection. The car is blazing fast, and quickly puts an end to other cars trying to keep up with you in turns. A REAL dream to drive, and always makes you turn around and look at it when you park it. Porsche, there IS no substitute.

Generally, I am very pleased with the car, but the poor gas mileage is a bit of a concern. Additionally, the small gas tank makes it necessary to refuel every other day. Just a heads up!

Are you having problems with your 2003 Porsche 911?

Hi there! As a car collector, I have high standards and unfortunately, this car doesn't quite meet them. I find it uncomfortable and the cockpit is a bit confusing, with some things being hard to reach. Is there anything that can be done to improve these issues?
Colten Stracke 2024-08-25
I appreciate your interest in Porsche NA, however, I would like to suggest considering the Infiniti G35 as a more cost-effective option. Alternatively, if you prefer Italian craftsmanship, there are some great options available as well.

Hi there! I hope you're doing well. I just wanted to share my experience with my car purchase. I was really excited to get a Porsche, but unfortunately, it hasn't been performing as well as I had hoped. Last week, I had a chance to race a Corvette Z06 at a stoplight, and it was really impressive! The Z06 was so fast, even on winding roads. Looking back, I wish I had opted for the Z06 instead of the Porsche and saved myself some money. What do you think?

I didn't write this before I sold my Porsche. However, after owning it for several years (1998-2004), the car began to fall apart both on the interior and mechanical side. The gaskets and plastic components were all in bad shape, and any replacement part would cost a fortune (check eBay). In comparison, a Toyota from the same year is like a tank and much more reliable. While the Porsche has a respectable 300 horsepower, there are many new cars with similar power. Is it worth paying $20K just to impress your neighbors? While it may be tempting, it's important to consider the difficulty of selling the car. Unfortunately, it can be challenging to find a buyer, especially since many potential buyers don't have the cash on hand. In my experience, the majority of interested buyers were over 70 years old, and I had to explain to them that the car is not easy to get in and out of and can be difficult to handle. Overall, it's a cute little car, but not the most comfortable for everyday driving.
