This video shows water leaking through the bottom of the doors because of perished inner door membranes. This is an extremely common issue we find on many different makes and models of car.
The Lexus RX 400 H you see in this video was with us for a 28 point check water leak detection service and to also make the car like new again. The car was suffering with more than one leak, in fact in total we have Successfully found Up to 5 different water leaks. This is not the first time we’ve had a Lexus of this caliber in for this process with more than one leak.
The one you see here was suffering with poorly welded seams around the roof bar and nearside rear including corrosion around the rear boot seal due to previous repair. All four door membranes were also leaking on this car So we fabricated a complete set and reinstalled the door cards.
The rear outside light gaskets were failing and a supporting bumper stop with screw also with failing gasket, common With cars of this age.
This Lexus has had updated replacement rear lights gaskets including the perished bumper stop gaskets And this proved successful with further testing but water ingress into the boot floor pan was still persistent.
We carried out a smoke test which highlighted issues with the vehicles welded seams around the top of the tailgate area we then cleaned and prepped the area with a bonding agent applying a waterproof sealant after. Due to common doorsill issues on this model of car the customer took our advice on removing the seals checking for any signs of corrosion making good and then applying a Sealent and reinstalling the seals.
