I would open up that door (like when I installed sound deadening material for sound system) to gain a greater scope of damage.
There seems to be a lot of misinformation in this thread. .
Me too. Would've done it before I even made this post...
As a matter of interest, that big plastic moulding is actually a sealed container and the sensor with the red clip is a pressure switch. If the container gets squashed in a side impact, the increase in pressure activates the switch which is and additional contingency in case there is not enough impact to activate the side impact inertia switches - the airbags still deploy.
I*ve seen owners cut a great hole in it to add bigger speakers...... oh dear!
Oh yeah I didn't cut nor alter that black sealed container thingy. I also added secondary weather stripping and that door feels, knocks, taps, and closes like a Benz ...okay maybe more like a BMW.
There is misinformation in the thread now.
Save the photo and have a proper look at it. Why would the sealer be scraped off when new and then left that way? The repair has been primed and quite badly too. You can see wire brush marks in it.
Leave the owner thinking his paint has peeled off under the door seal for no apparent reason if you think it will make him feel better, it doesn*t really matter to me.
There is definitely some misinformation in this thread. The door looked like any other door does PRIOR to me uploading the picture. When I was drying the car I noticed the paint was bubbling adjacent to where the seam sealer is. When I pushed on the seam sealer I could see it was cracked and water was being pushed out from in behind the seam sealer when I pushed on the seam. As I mentioned in my original post, I started scraping the seam sealer and paint off to see the scope of the rust and the total affected area. Once I did that I took the photo. So, what you're seeing in the photo is after I removed the paint and seam sealer with a small flat headed screwdriver. Prior to that photo you would have seen an intact door with very minor bubbling of the red paint adjacent to the seam sealer.
I have taken the vehicle to two independent body shops (one national chain and a small shop). Both have concluded that the door has never been repaired before and that moisture found its way behind the seam sealer and started the corrosion. Its currently in the shop being repaired.
The purpose of the post was an FYI for everyone else who owns a similar model year to keep an eye out for corrosion along the door seams. While the vast majority of the CX-5s out there are likely fine, there was obviously an issue from the factory with mine.
Joe, did you take it to a Mazda dealer and show it to them? A visual inspection. And they said the warranty doesn't cover it unless it's perforated??
If so, that blows my mind.
Most car manufacturers only cover "rust perforation" which essentially means the vehicle needs to rust through the metal completely.
You may want to have the Body Shop look at whether any of the door drains on the bottom of the door and/or weather seals at the top of the door are compromised or damaged.
Precisely. Read the corrosion warranty. It covers perforation (a hole) only. I did not take it to the dealer because I knew they wouldn*t cover it under warranty.
The vehicle is in my signature. It has 266,000km/166,000 miles, but as previously stated has been oil sprayed annually and has been very well taken care of. Vehicle was built in April of 2014.
I have a 2018 and the rear doors drain poorly. My rear doors may rust over time like yours if i'm not diligent to open the doors to let the water run out after a wash or pouring rain.
