Honda Ridgeline Water Leak Problem – Causes and Solution

The Honda Ridgeline water leak is caused primarily by a manufacturing flaw. Because of this, the issue only involves a few specific models. There are three common causes of leakage. The first is sunroof tray damage, the second is a bad window seal issue, and the third is a puddle light/AC issue.

Water leaks occur in a few specific Honda Ridgeline vehicles. The car’s interior is most affected by this issue, particularly the carpet and weather tech. This water later entered the engine areas and created risks.

Fixing the leakage and resealing the seam area can solve the issues primarily. The damaged parts must be replaced for a long-term fix as well. Read on to learn more about the issue.

What Causes Honda Ridgeline Water Leak Problems?: And Their Solutions

Customers frequently complain about the water leak issue with Honda Ridgeline models, particularly the 2021 and other older models (According to some customers, the 2006 version has the same issue).

Numerous factors are at play here. We’ll look at each one individually and attempt to determine the best course of action.

#1 – Leaking Sunroof Tray

This problem may be brought on by improperly sealed car roof seams. The seam in the Ridgeline car is sealed with a rubber joint. The production of the Honda Ridgeline’s 2021 model has some issues, which indicates that the seam wasn’t properly sealed.

As a result, when you wash it or drive through rain, the car leaks water that gets inside. Water from those leaks then soaked the carpet, seats, and other interior elements.

Solution:

The initial Honda Ridgeline maintenance for this issue is to reseal the seam (your dealer will do this if it is still covered by the warranty). However, if the vehicle ages or the issues persist, you will need to have the seals replaced at auto repair facilities.

#2 – Bad Window/Windshield Seal

Similar to the previous issue, a bad window seal can occur in any window, be it a front window (front windshield), side window, or back window. And the water will undoubtedly get inside the vehicle if it’s not properly sealed.

Accordingly, during washing, when the seal gets wet repeatedly loses its stickiness, which is why it leaks. This is a big drawback of Honda cars.

Solution:

Resealing is the one option. But as we already mentioned, if the leak reappears within a few days, you’ll need to replace the window’s entire seal.

#3 – AC or Puddle Light Causes Passenger-Side Puddle Woes

You may occasionally see water accumulating in the space beneath the footrest. This has happened for a number of reasons. But the malfunctioning cooling system, particularly the AC, is the main cause.

This is due to a damaged or improperly fitted gasket. Another cause of the water accumulation in the footrest area is a puddle light that is broken or ineffective. When driving a vehicle on a rainy day, water will enter through that part.

Solution:

You might not easily understand by looking at which one is the culprit. So you should hire a professional to troubleshoot. If the air conditioner causes the problem, look for a faulty gasket, improper sealing, and a cracked hose.

Take the right steps to solve the issues accordingly. However, if the problem is with the paddle light, locate the gap or misfitting and double-seal the area. Nothing will change if the paddle light is changed.

#4 – Exhaust Pipe Leaking

When the engine is cooling, exhaust gasses, including water and carbon dioxide, pass through the combustion chamber. This temperature change gradually damages the exhaust pipe, which is later discovered to be leaking. If there are leaks, you will notice water dripping under the cars.

Solution:

The first step is to seal the exhaust pipe where the whole has formed. If there are multiple holes/leaks and the sealing will not last, it is better to replace it.

#5 – Head Gasket Leakage/Car Cooling System Leakage

A car’s engine head gasket is crucial. When a head gasket fails or leaks, the engine’s internal pressure, and fluid are contained. The engine cooling system is shut down when coolant and engine oil mix. The cause of gasket leakage is high temperature and high pressure.

Solution:

The leaky gasket needs to be changed out for a new one to solve this issue. Usually, gasket prices are quite cheap you can buy one for $30 to $100 dollars. But installing a gasket is labor-intensive work. So take professional help to get the job done.

#6 – Car Cooling System Leakage

A leak in a car’s cooling system can lower the coolant level and cause the engine to overheat. Usually, radiator leakage happens due to a damaged radiator. But it can also happen when your hose is broken or the water pump is faulty.

Solution:

You must first find the location of the leakage. The damaged components should then be changed. Then again, refill the cooling system at the right level.

FAQs

If you want to learn more, don’t skip the following questions and answers about the Honda Ridgeline problems with water leaks.

How should it be tested to identify the issue earlier?

One method is to spray water on the car’s joints. You need to take a sprayer and spray the joint of the window, roof, and air shield. You will see water inside if there is any leakage. Another option is to leave the car outside in the rain.

Check the car’s interior after a short while; if water is present, there is a leak in the top areas.

Can this Honda Ridgeline car leak be fixed at home?

Yes, but it wouldn’t be wise since you’d need some difficult-to-manage professional equipment. However, if you have prior knowledge and all the required materials/tools at home, go ahead and try it without hesitation.

However, it is safe to seek advice from professionals.

Is this leakage causing more serious damage to Honda Ridgeline vehicles?

Any vehicle that has water leaks is always going to suffer. In this instance, water is slipping into the car’s floor from the top and sides. It will eventually wet the weather tech and carpet. After some time, it will begin to emit unpleasant odors and attract insects.

Key Takeaways:

Several Honda Ridgeline vehicles have a serious water leakage issue, particularly some models from the late 2000s and 2021. Multiple car parts are associated with the problem, including the window, air shield, lights, exhaust pipe, sunroof area, etc. From the discussion, you can note some key points as follows.

  • Sunroof tray leakage, bad window seal, exhaust pipe leakage, ac damage, head gasket leakage, and car cooling system leakage are the six common causes of water leaking.
  • Resealing is an option, but replacing the specific part is preferable.
  • Repairing the issues by a professional mechanic is suggested.
