Fortunately, I’m not part of this recall even though I’m at the tail end of the affected date range. If you haven’t checked here’s the description of the issue Kyle has and link:

“Tesla has issued a voluntary recall on certain Model Year 2024 Cybertruck vehicles produced within the build dates from November 6, 2023 to July 30, 2024, that are or were equipped with metal-oxide-semiconductor field-effect transistors (MOSFET) in the drive inverter. The affected population includes vehicles equipped with Inverter Part number family 1802305 containing MOSFET part number 1530063-2A-B.”

Kyle is also absolutely right about the “front axle clunk” they need to fix that it’s my only continual complaint with my truck and it is jarring and kind of embarrassing if you got passengers. I didn’t have the vocabulary to explain what was going on, but at right around 27:50 he does a great job of explaining this issue.

From my part, I hope they can just bais it towards the rear end as a permanent solution. I don’t know why they didn’t use the same set up as the Model S Plaid in the first place dual permanent motors in the back.

That felt like a fair and real video. Facts are just facts. Unfortunate that bad MOSFETs are causing issues.

If you have a perm drive unit that is rev 6 or older you will probably need a replacement. They are currently on the 7th version of that motor. All others have had some sort of problem with them. But doesn't seem to affect all units within these versions.

Perhaps I should know the answer already, so sorry if it’s a dumb question. How do I find out what version I have is that in the service menu somewhere?

I don't think the AWD people on here understand what we are talking about. Going from a Lightning to a Beast and I said the ride quality is much less comfortable, everyone on here said I was insane. I love the truck, but you're right, when it feels like I'm hitting a wall when I go over a small bump it is embarrassing. I am glad he also mentioned the noise, there are times the Beast really screams at you in a high pitched shriek.

I didn't realize how much different the Beast was compared to the AWD, until he put everything I experience into words in this video.

?!

I didn’t realize it was just basically front wheel drive hop because I’ve never owned a front wheel drive vehicle (with the exception of our PT cruiser which was my wife’s daily at the time). The only reason I even know what he’s talking about is because I’ve experienced it in rental cars.

The very first time I experienced that clunk was on my way home from the SC after I delivery - driving through my neighborhood and I thought “oh man, they really have not dialed in the suspension yet!”

And you’re absolutely right “hitting a wall” isn’t an exaggeration at all and this can be the tiniest, as Kyle put it, ‘negative space’ like a 1 inch deep pothole or any other surface variation. If it’s positive (ie convex instead of concave), no problem!

And since the suspension is so incredible the rest of the time, it’s really incongruous and jarring! I’m assuming they’re going to fix this with whatever other suspension goodies they give us along with app control.

The rough wheel hop is really pronounced on washboard dirt roads under acceleration. It feels like the suspension banging, but it's the front wheel torque causing skipping and grabbing. If they try to fix it with some kind of traction control software, then it will feel like a loss of power. I'm not sure how they could fix it while getting power to the wheels but I'm not a powertrain guy.

Weirdly, I’ve never experienced that. Because I always put it in Baja or off-road mode when I’m going to my remote property or somewhere where washboarding is an issue. Kyle calls that out as an on-road solution during his video. In my experience in either of those settings my CB does 1000 times better than my FJ. I feel perfectly under control.

Are you using one of those modes?

 

[Dazureus]

No. There are a few dirt roads where I live and sometimes drive on for convenience, but not often. When I blasted over the cobvle portion of our test track, I did have it in off-road mode and didn't experience any harsh feel so I believe it that these modes do something. It's just not convenient to switch modes when I'm just hitting a few miles of dirt road.

Yeah, I think that was Kyle‘s exact point - that while these modes fix it (I’m glad that you can confirm that that’s the case even in your scenario) that it’s dumb/annoying to have to do that through multiple menu clicks, and Tesla should just make the necessary software corrections to eliminate this problem.

I agree!

Wait! “Test track?” Umm, please say more. ?

The problem exists for AWD (rear main drive primarily) but not as pronounced. You can definitely feel some weirdness when you roll off the bump like a wheel slip.

Huh, I haven't experienced that. Only issue we've had is it dropping power if it slides on a snowy right angle turn. Do you drive in Beast or Sport (what we use) mode?

I work as a software engineer for a steering OEM parts provider. We have a test track that has various surfaces, the roughest being th cobble portion. Basically large rounded rocks 8-10 inches in diameter. We weren't directly studying the ZF steering units but I got access to have some fun.
