B Pillar plastic issue

[gronsay]

In the old days when someone got a new car jokers would add gas to tank every night ,owner would tell everyone how great the mileage was .
Then next few weeks take some out and let owner try to figure it out.
Maybe vandalism or jealousy is at play here

haha, adding gas is hilarious

I work at a dealer as a tech and I have seen this many times. The sun is reflecting off a window or another surface and melting your trim. 100%

As soon as I saw his picture I thought of this:

Yeah, agreed on this. Especially with the angle that it has. I had the same thing on one of my cars and a stripe on my grass due to my neighbor’s side window. It catches the sun for only about 10 mins, but that 10 mins has two spots on my property like an ant under a 12 year old’s magnifying glass. At some point during the day, something is reflecting sunlight onto your vehicle.

I thought vandalism as well or someone trying to break in by using a heat gun to make space behind the glass. Doesn’t make sense with a soft top they could cut. All signs lead to chemical. With the amount of cameras in my neighborhood, I highly doubt it’s vandalism.

I was thinking of something like one of those little pocket torches some folks use for lighting up...stuff. I've seen those glossy black panes on Lincolns and other Fords oxidize but never anything like this that hasn't been involved in a fire. Crazy.

I have patch grass the dies every year on my front lawn. Played with the sprinklers, seeded, weeded. no difference. Grass always grew nicely in spring, weird triangular dead patch by fall. Two years in I discovered that at a specific time of the day, certain months of the year, the sun is focused by the front, second story window and sweeps a death ray on part of the lawn.

Try parking the Bronco in a different location for a couple of days and see if the situation gets worse.

Was just going to say check your window reflections at home or work. I remember an old co worker had something like this from the front windows of his house. He started checking it every hour or so if I recall and figured it out. Like a magnifying glass...

It’s parked in the same exact place as I parked my base F-150 and Yukon for years and never had this issue. I highly doubt it’s a reflection of magnified light. I’ll try a different spot to rule it out.

5 days after I’ve had my Bronco, I go outside to get in the vehicle and notice a deformity on the exterior of the B pillar. It looks like something is melting it from the inside, but the dealer took it apart and everything looked normal. They also noticed it’s happening at the C pillar.





The next day, the issue got worse.


Then the following day it started to spread in a different area. Of the B pillar. The weather has been high 50’s during the day and high 30’s at night, so not that drastic.

Legitimate question: Do you park near a building with curved glass windows? There have been cases where the sun can reflect and be so focused that it could deform plastic.

But neither of those have a plastic B-pillar.

I’ve seen that happen before but I park it at my house at the end of the driveway at basement level somewhat far from my dirty windows. My backyard leads to a county park full of trees. I haven’t been driving during the day since this started.

You gotta take care of your plastics.
