Which Porsche 997 Years You Should Avoid and Why?

The Porsche 997 is better recognized as the Porsche 911, Porsche Carrera.

German automobile manufacturer Porsche AG first introduced its first Porsche 911 sports vehicle model in 1969. But the manufacturer started using Porsche 997 as the internal designation for Porsche 911 between 2004 and 2013. 

Therefore, all the Porche 911 sold during this period are considered the Porche 997, and even in this shorter timeline, consumers reported some years’ Porche 911 or 997 models to be problematic.

Read the following article to know which years Porsche 997 models are troublesome, what are the most common problems of them, and which years Porsche 997 are safe.

Porsche 997 Years To Avoid (List of Years)

Porche 997 was referred to as the better-modified version of the Porche 911 model. Porsche AG claims to revise the engine as well as make significant interior and exterior styling while bringing Porche 997 into the market as the 2005 Porche 911 model.

However, that does not mean these models are entirely faultless. Also, based on numerous consumer reports, there are few Porche 997 models to consider as problematic.

Let’s understand the real reasons behind considering those models as the worst and why one should avoid considering them-

What Makes These Porsche 997 Years Worth Avoiding?

Thus, let’s see what are those most common trouble that one should be well aware of while owning or using a Porche 997-

1. Porche 997’s IMS Bearing Failure:

If you have read my previous discussion on the problematic Porche years models and why they are better to be ignored, you must have already noticed that users reported encountering this particular issue.

It was highly disappointing since the fixing is not cheap, and no one wishes to deal with such expensive servicing for their newly brought vehicle.

When the IMS bearing loosens or fails, it effectively causes catastrophic engine failure, and this issue was significantly visible in the Porche 997’s earliest first-generation models.

Especially in the initial 2006 Porche models, you will experience this problem.

However, the manufacturer has improvised this feature by inserting a stronger factory-fitted IMS bearing, and this problem is no longer available in later released 2006, 2007, and in other later released years.

2. Porche 997’s Scoring Bores Issue:

Another major engine issue is the scoring bores, which commonly occur in Porche 997 vehicles.

According to the user’s real-time experience mentioned on the Carcomplaints website, the dreaded bore scoring issue eventually causing severe damage to the vehicle engine or complete engine failure is well known among the Porche user’s community.

This issue is mainly significantly available in Porche 997’s 2005 model.

But unfortunately, some dealers do not share the information during the sale, and this particular failure ultimately causes the user to replace the entire engine.

According to one user, this replacement can cause someone to spend a minimum of £15,000, which is definitely a costly servicing task.

3. Porche 997’s Cooling System & Window Failure:

Besides engine-related problems or failures, several users have also complained about Porche 997’s defective cooling system and window.

On the Carcomplaints website, Users have reported noticing an enormous wet spot under their car after returning from a short trip, and when they investigated further found that the cooling fluid is gone.

Even after filling up the fluid, users noticed all fluid draining away through the leaked hoses and had to visit the repair shop to fix it. Also, this problem mainly arises in Porche 2009 models.

Another major issue that users experience with the Porche 2009 vehicle, is the window open or close failure.

One user mentioned in the Carcomplaints that the small rear windows of their Porche vehicle tend to stay either open or close when the top is opened or closed.

Even in some cases, both windows fail at the same time, and the only solution is replacing the window set, which can approximately cost nearly $1400.
