Is it only when accelerating or at a constant speed?

I'm pretty sure it's at constant speed as I*think* had AP enabled at the time... Not 100% sure though.
I'll have to be aware of this next time I'm at higher speed.
Doesn't sound like the noises in that link to be honest but I'll listen again later with proper headphones to be sure it's not the acceleration noise.
And that’s a stupid but typical response, the notion that someone being held against their will might be saved because the rear window glass was clear , is fanciful, who looks in the window of a car while it’s whizzing past ?, unless the driver happened upon a Garda checkpoint, the effect is near zero
usual government PR policy reaction which ends up causing problems in other areas
besdies , a distinction should be made between taxi and Hackney, a Hackney can’t randomly roll up and with no roof sign , no oblivious victims are going to step in
Regulations are clear tinted rear windows aren't permitted for Taxi/ hackney .... its not unique to Tesla. You may well have and are entitled to views on this and many of the other regulations but it is what it is Posters have put forward helpful suggestions in good faith but all relate to complying with regulations. Relevance of discussion on Tesla specific forum is another issue....
I’m merely highlighting the “ seen to be doing something “ nature of government which fixes nothing but creates obstacles in other areas
it’s a stupid regulation and should be abolished
Mod Note: Complaints about current taxi regulations are off topic for a vehicle specific thread, move on.
I wasn't able to get out again in the car in a higher speed scenario (M50, N9 etc) but this video is pretty much the same sound I get though mine is a MYLR and the sound kicks in over 80km+. But gives an idea as to the sound I'm on about.
Plenty of other users complaining about the same issue over on Reddit and various Tesla fan forums too, so seems to be a world wide problem, not just a Shanghai built problem.
This is pretty serious fault. You'd have expected these parts to have never made it near a production line at all. And not stress related manufactured and installed from new.
Now to wait to see if this is limited just to some cars.
Hopefully not as widespread as the E46 M3 sub frame issue. Valdas in Motor Confidence had to replace the sub frame. There are welding options available but under warranty this should be replaced without quibble.

A nasty job to replace that I'd say? I'd imagine there would be significant amount of stripping to get it out. Doesn't the Y use this new gigacast so that might require the entire front end of the car to be stripped out to get at that cast? Not sure I'd be happy getting my new car back after that replacement.
Not sure I'd be happy with a weld either as prospective second hand buyers will immediately turn off when they see that and think you've crashed it and done a botch repair.
I hope its a one off issue for Tesla's sake!
Having said that, Merc have buried their head in the sand for something somewhat similar (rust rather than immediate failure though) for their E-class and only fix it when it fails NCT! Thread on it here!
That’s rust on a 13yo merc though, versus an actual crack on a brand car one which is using a new production method.
it’s also not comparable to the e45 m3, a car designed in the late 80’s and maybe 75,000 of them ever built (and not nearly as many M3’s were affected as people always think. The difference with the M3 was that it was a car with a cult following, so any cracked subframe issues were known within the community but affected relatively few overall).
its like Tesla panel gaps - everyone knows to check, but not many cars had them.
At most, this Y issue would be an inspection recall maybe.
Right, that is why I pointed it out as rust vs immediate failure! ;)
Btw, the rust failures happen much sooner than 13yrs. Presumably car location/parking affects the rate.
its not really the point I was making though. What I’m saying is that manufacturers have form when it comes to stuff like this.
Let’s see what Tesla do and how prevalent it is… like i said, let’s hope it’s a one off.
Thats a cast failure, not a stress failure, the crack is too wide, it looks like some sloppy ash/dross mix aluminium was injected into the die, it could have happened at the start of the melt or towards the end of melt, the die is dirty and showing signs of damage, I will do a picture later explaining it.
I knew about the tesla injection moulded parts, but looking at that casting some of it looks like a sand casting.
Any way its one casting, it does not exclude stress failures on other castings, such a large casting its a big gamble, most other car manufacturers biggest castings would be a gearbox or engine block, not the front / rear end of a car.
Is it fixable or complete replacement the only option? If complete replacement, I assume the cost would warrant just handing them a new car?
That video is very "up close" for a novice like me. Can someone please point out exactly where in the car you could check to see how your own car is holding up?
Thanks
That was a stress facture that would appear over 10 years later tbf. Not cast imperfections that made it on to an assembly line. Chalk and cheese.
Does anyone know whether Acceleration Boost causes any insurance implications for the Model Y? Is it classed as a modification?
The only people to ask is your insurance company to be honest.
It’s like an old school remap. Will the insurance company find out? No idea. Would they check? Would they know how to check?
There is free Tesla supercharging until 11pm tonight to mark 10 year anniversary of the first charger being made available in Europe. Saw it pop up on Hotukdeals and just checked Enfield in the Tesla app. Seems legit?
Had a look at a few others, and it looks the same. Apart from a short wait in Sandyford, there's lots of availability atm.
I'll answer my own question in case any one else was wondering! In the case of my insurance company (AIG), they didn't class Acceleration Boost as a modification so it doesn't affect your policy.
Ignore the crack and the little bit of daylight, the other lines and marks, they are the result of cold aluminium or cold die or dross mixed in with the aluminium.
This confused me for a while, its a sand core, its basically a sand and resin mix made into that shape and inserted into the bigger mould and cast, the sand is washed or broken out after cooling down.
I had thought the textured effect was a build up of coatings on the mould, for releasing etc, and the 2 dents on the edge of oblong hole was mould damage but its a sand mould and its to be expected, if you look at the upright above the same hole, you can see lumps on a mostly smooth surface, they are voids in the sand, from air pockets or grains of sand falling out.
You could weld up the cracks, but do you want to, its like an alloy wheel after welding, can you trust it.
I don't know if the castings are heat treated, another thing about welding aluminium, it will look fine until its melted and starts dripping 660c rain, then its a bigger hole you have to fill with weld, a little at a time.
Tbf these are a pretty big deal considering the power capability of a Tesla motor. There's a reason aluminum is avoided in stress situations in manufacturer over the likes of steel or alloys.
Relatively new mass methods tesla are deploying but equally Inherent risk. In many ways that car is no different than a cut and shut of old with stress lines like that on Integral structural parts. I wouldn't remotely be satisfied to hold on to it having forked over 40 k for one.
Good analysis. It's die casting in grand scale and pressure in case of Tesla and the technology is very new (IDRA is the supplier). Hopefully it's just a single case of a failed casting as replacing the full front of the Model Y would require Arthur Tussik level of botchery. The gigacasting is bonded to the passenger cell structure. I don't know if any fasteners are also used.
Does that mean that frontal impacts that would be repairable in most cars are write offs for Model Ys ?
I believe its low pressure, or maybe even gravity fed, its unusual to mix sand cores and pressure casting, not saying that its impossible, I never seen it before.
I showed the pictures to a guy with 50 years experience, first thing he said was "shite aluminium", 2nd thing he said was "whats it in?", when I told him a model Y 3rd thing he said was "fu*k$ sake".
Hard believe it made it into a car, so many steps from casting to assembly,
Large alloy castings are rare for a reason as listermint pointed out, Maybe it will work, time will tell, reminds me of the comet jet, everything was grand till they started falling out of the sky.
They use these machines:
https://www.idragroup.com/en/gigapress
so definitely not sand casting. There is an interesting video about gigacasting discussed here:
https://youtu.be/IgTNynoVX-I?si=tJscCSWaOAiX2A92
In regular steel bodied vehicles once the damage goes past the crumple elements ahead of wheel wells the structure can't really be repaired/would be too expensive to repair. Some concerns have been voiced about repairability of the gigacasting based vehicles alright. But it should be possible to cut out the damaged casting and bond in a repair section, just the process is quite different. The body shops will need to upskill for sure.
