At Louden Motorcar Services we’ve been working with quality German vehicles such as Porsches since 1977, so we definitely know a thing or two about these famous beauties. Here are a few examples of some of the most common issues that Porsches seem to be prone to:
The AOS, or ‘Air Oil Separator’ is an important part of your emissions system, and when something goes wrong it can cause emissions problems in the beginning and quickly escalate to leaks from compromised seals. As such, an experienced Porsche mechanic will keep an eye out for issues with your AOS and so should you!
A very common problem with Porsche vehicles is that their batteries often end up flat. The reason for this is simple – If they’re driven only on special occasions, the battery is still going to steadily drain if you don’t top it off from time to time. In this case, no repairs are needed, just a battery accessory you can get at any good auto shop.
With some manual transmission models, the op-sleeve or dog ring can degrade or become otherwise damaged, causing an issue where second gear can slide into neutral on its own. This is potentially dangerous and oftentimes requires the replacement of both of these parts to properly remediate the issue.

Porsche vehicles are on the high end of repair cost averages, usually costing around $1200 per year to repair and maintain. Regular preventative maintenance is definitely important with these vehicles if you want to keep the costs manageable and head-off any bi problems before they can come back to bite you in the wallet.
It’s all part and parcel of a high-performance vehicle of this nature – These vehicles are coveted around the world but they need a lot of care to deliver that unique Porsche experience.
We provide both routine maintenance and performance-focused services to help keep your Porsche running at peak condition.
Yes, we service a wide range of Porsche models, including sports cars and SUVs, with precision and attention to detail.
Porsche maintenance can be costly, but working with an experienced independent shop like us helps keep costs manageable while maintaining high-quality service.
Located between your transmission and engine, the Porsche’s rear main seal is one Achilles heel for these world-renowned vehicles. Designed to help keep oil inside of your engine where it’s supposed to be, time and normal wear and tear can cause these seals to become compromised and then you’ve got a problem.
With regular preventative maintenance by mechanics who know their way around Porsche vehicles, this won’t be an issue, but it’s definitely something that comes up a lot with certain models and in cases where the vehicle hasn’t received regular service in some time.
The most common causes of a voided warranty are lack of regular preventative maintenance and unauthorized upgrades. With the former, it’s not really unfair – These are high-performance and highly-desirable vehicles and you need to take care of them to maintain their value.
With the latter, it’s also just common sense – Adding an unauthorized upgrade is going to put a strain on your vehicle that the original engineering is not designed to handle. As such, modifications of this nature might very well void your warranty.
You can trust Louden Motorcar Services for Porsche service in Dallas, offering expert care without the high cost of dealership service.
