Lawsuit Investigation: Porsche Sunroof Leaks, Drain Problems

If you drive a Porsche and your sunroof leaked or you had other problems that may be related to the water drains in your vehicle, attorneys working with ClassAction.org want to hear about it.

They’re investigating whether a defect in the sunroof and/or drainage system is allowing water to enter the passenger cabin and damage the interior. If a defect is suspected, a class action lawsuit could be filed to help affected drivers.

Before attorneys can even consider taking legal action, they need to learn more about the problem and how many drivers have experienced it.

Driver Complaints: Leaking Sunroofs, Clogged Drains

Here is a sample of complaints from Porsche drivers who experienced leaking sunroofs and drain problems with their vehicles [sic throughout]:

Very excited to get back into a Cayenne…However i just went through the carwash for the first time and ended up with a puddle on my back seat. Panoramic roof was leaking in the middle panel. Anyone ever have theres leak?”

 Big rain today in New England - I go to my car and noticed a wet spot in the passenger seat (just a small area). The roof was not left tilted open. It appears to be dripping through the visor area. Naturally I will be taking this in to the dealership… I did notice there were some instances of the issue mentioned on Reddit.”

My car is 2 months old, a miami blue macan. Leaks like crazy. It has been in the shop three times in the past month. They can't figure it out. Call corporate and start a file. You need to do this before you go the lemon law route. My car has been in the shop for the past 7 days, and they have no clue when I will get it back. Most frustrating experience…So done with Porsche and their leaky new cars!!”

FWD sunroof drain lines completely clogged. Removed each drain line from each footwell/firewall interface and cleaned. Flushed water through the lines as well. HOWEVER, we identified that water when backing up drain lines and into sunroof overflows into sunroof tracks. This water goes STRAIGHT DOWN THE PILLAR and into the footwells on each side. Assuming there is no failure in the sunroof tracks, but just that this is a flawed design. The only remedy I know of is to ensure the sunroof drain lines are kept clean and draining. Another one to add to the Cayenne Maintenance list.”

2016 Cayenne - Pano roof Had a water leak in the rear which ruined the sound system, covered under warranty Now after a big rain a large leak on passenger side, opening the door and water poured out after a huge rain storm Anyone else dealt with this?”

When we had heavy rain at the start of the year I realised that I had water getting into the rear seat area on both sides of my car. Given it is parked outside all year round (I have no garage), I did what I could to dry it out at the time and put a car cover over to prevent matters getting worse. As we have had some decent weather during lockdown, I have since removed the rear liners and cleaned out the drainage channels (which were a little gunked up but not blocked…I then started trying to track down the leaks in earnest. With the assistance of my daughter, we poured a few gallons of water over the sides of the hood and I found no water getting anywhere it shouldn't.”

We have a Porsche with wet front carpets and the water is leaking into where the electrical control units are. Although these units are usually well sealed, water and electrics don't place nice together. We stripped out the back of the car and found that water was running down inside the hood, as it should, and flowing to a trough which was overflowing.”

While a vehicle’s drainage system needs to be cleaned regularly to prevent water from pooling up and damaging the interior, attorneys working with ClassAction.org are looking into whether a defect is contributing to the leakage problems consumers have reported.

How Could a Class Action Lawsuit Help?

If filed and successful, a class action lawsuit could help consumers get back the money they spent repairing damage to the passenger cabin and having their drainage systems inspected or cleaned. It could also force Volkswagen, the parent company of Porsche, to provide a fix to drivers, free of charge.
