SeaSucker cracked Tesla Model 3 rear glass
 

Hmmm... I used a Sea Sucker on the rear glass of my Honda S2000 hard top for years. I wonder if Tesla has thinner or weaker glass than common?

Was it just the suction that cracked the glass? If so, I'd say the glass was definitely defective. Those big suction cups are just like the ones glass installers use to handle windshields, etc.

Tesla skimping on glass

That's the Tesla service rep trying to save his company some money.

Would never waste money on a Tesla. Way too proprietary and way too customer unfriendly. Sea Sucker seems to have done just fine on a whole bunch of other cars. I could see if you put a really heavy bike on it, that could cause issue but I doubt most folks would do that especially if they bought Sea Sucker.

After having worked at a glass shop when I was in school, there is no way I will ever use any rack that touches the back glass in any way. No matter how many racks are out there that utilizes the back glass, it is an extremely poor idea. While you can have great luck with one, it doesn't take much for that luck to disappear and the glass to be broken. Sorry, as much as I would love to fault Tesla for this, it isn't their fault, the back glass isn't designed for that use.

+1 on not using glass for transporting. That's just asking for trouble.

FYI, you're not really supposed to test the installation doing this

+2. Ain't gonna happen. It's one reason I bought a Forester. Even my large LHT can fit in the back with both wheels on.

Not to dismiss the OP's plight, but the roof of my car is glass, and there's no way on this green earth that I would stick a suction cup bike rack to it.

But this does come from a guy who, through the random cruelties of the universe, is on his 4th windshield. I barely trust glass to keep the rain out. I'm not counting on it to keep my bike attached.

Is there some reason it won't suction grip to the metal section above the glass? Perhaps even to a degree that the back tire lays on the lower metal below the glass?

It would seem to follow reason that an electric car would shave weight anywhere it can. Glass is heavy. I do wonder how they did so and still met the requirements of the protection and safety standards for the auto industry?

You know, they take weed breaks at the factory, right?

Buy a truck. That's what I did (16 years ago). Problem solved! No need to dismantle any thing either.

I don't think it has anything to do with the proper testing process for the rack, I wouldn't do this because that seat angle and riding position sure look uncomfortable. If I'm going to go through that I at least want my doctor to tell me that my prostate's ok.

^^ It's OK to test like this as long as you use quick release shoes ^^

Put a receiver on the car, and use a hitch mount rack. That was my solution. I have had no issues and no worries.

Glass shop? As in automotive glass?

Yes, among other types of glass.

What was the weirdest or funniest reason for a glass replacement that you've seen?

I honestly couldn't tell you, that was 35 years ago.

Transport via windowpane was known to have worked really well and that was 50 years ago. Though I did hear of some getting in trouble.

the Wonkevator?

Yah but with it in the bed of the truck, it won't be the first thing creamed if some a-hole rear-ends me.

Invest in a Roof Rack..

maybe your Glazier-supplier can get you a superior specification of Glass,
for the replacement back window?
