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.

Should You Buy A Used Porsche 997?
For those who have a budget limit, buying a used Porsche can be an excellent option. However, before you go for a used Porsche, educate yourself so that you do not make an expensive mistake.
The first thing you have to decide is which model year of Porsche 997 you want to buy. We briefly mention the IMS issues. If you buy 997 in 2007 and a letter you should not worry about it since the issue has been resolved in 2006.
Similarly, read about bore scoring and other relevant aspects that may result in engine failure . Bring an expert to inspect the vehicle, who can identify the fault.
