For those who may not know, the rear glass may pop/crack because of trapped heat due to the tints blocking the air circulation. Learn from my mistake. Don’t tint your back window. I’m paying $1,600 or above to replace the rear glass.
not sure I'm understanding how tints block circulation. Glass is not porous. How could a layer of film make it less porous?
The defroster gets too hot, causing the glass to break in colder temperatures. It’s like trapped heat.
that's not ventilation or circulation though. That's direct heat.
I bet over 50% of the community in here has tinted their rear window with no issue. More than likely the tiny shop damaged one of your defroster lines which led to a concentration of heat in a compressed spot.
Even if I had the tints for 5 years?
Yeah I’d say it’s much more likely than the tint trapping the heat somehow. When those defroster lines are damaged, the same amount of electricity has to flow through a much smaller circuit, which inevitably leads to hot spots.
5 year old y here. Northern snowy climate with tint. No problems here.. I've used "defrost car" and regular defrost while driving with zero issues
Have tinted every car I've owned as I live in TX and most if not all of them have had defrosters on the back windshield. None of them have cracked. I also have a coworker in another state who did have a back window crack immediately after turning on their defroster and they didn't tint. People love to jump and blame tinting, Tesla included, just like with the cracked lightstrips.
This... Doesn't track. I've tinted the back glass of 20+ of my cars, sometimes with ridiculously thick/heavy tint. The glass transfers heat to the tint, which transfers it to the circulating air. I've even done thermal videos before and after and there's no significant difference. My Model S currently has a very thick ceramic 20 on the back, and has been through all the seasons with no issues including extreme temps on both ends of the spectrum. I think the much more likely scenario here is that a micro-fracture or other imperceptible damage finally gave way when the defrost was on. Or defrost was on and glass was hot, and got hit by cold water/ice/slush/snow... I've seen that one more than once.
Bad advice from OP. He has no clue what he’s talking about 🤭
sigh: at tints
