Cybertruck defect on outlets - Tesla can't fix, going to buyback

[cybertruckvegas]

No it's a weird bug:
110v outlet works fine most of the time though I did have a weird HV battery error a few times but can't reproduce it so just let it slide

240v outlet works fine if car charge is below 71%. Eg when Tesla said they fixed it the first time I tested it immediately and it was fine - truck had 66% charge.

I charged it overnight and it stopped working eg outlet instantly resets anytime more than 100W is applied to outlet. Easiest way to tell without getting into a fight about what equipment was plugged in was to test the mobile car charger with another car.

Car has 80% charge + outlet = no go

Drive it down to 71% charge -> now works

Charge it back up to 80% -> no go

Drive it back down to 71% charge -> works again

Repeated this like 3x to where I know if it's >75% it doesn't work but <71% it does. Didn't test 72,73,74 but that's already super fine margin.

I planned to use the 240v to do welding jobs. Sure I got a generator but whole point was it had 240v to power the welder to justify $110k cost.

Regardless lots of Tesla fanboys and I'm also a big fan eg I got 4 Teslas in addition to this CT as well as Starlink mobile + mini.

But it just needs to work.

Just a clarification from the op please. You say the 240v outlet stops charging the other vehicle at under 75% and won't charge a car above that number but works fine up to that point? Also (maybe I missed this) does the same apply to the 110v outlets and do other devices work normally when plugged into the 240v outlet and 110v outlets(ie. power tools, etc.)?

Also I put heavy load on the 110v outlets and it was also ok eg 110V at 10amps = 1100W x 2 outlets total 2400w no problem. Just instant reset of 220v > 75% charge @ even 1A = 200W.

Those guys already tried to fix it once and then they couldn't figure it out so had to get with "engineering" who told them to test all the wires - sounds like shooting in the dark to me.

I highly doubt them replacing some wire harness is going to fix it when they replaced the entire HV converter last time to no avail.

Again it works fine at 71% charge - just not at 75% or 80% or 90%. Sounds like software bug to me but of course those guys are the most expensive engineers so Tesla going to say give him the money is my guess.

You seem to think that the entire vehicle is at fault, it isn't There's only a couple of pieces of the vehicle that provide the power to the outlets.
And the biggest parts that provide the power are the same inverters that charge that battery from AC.

If it was a generalize software bug, then everyone would have the problem, wouldn't they?

Thanks for the clarification. My confusion was your use of the word CAR. You mean when your truck is 71+% charged. I thought you were referring to another car being charged with your truck.
I've only used my 110v outlets so far. This makes we want to give the 240v system a try with a high SOC.

It worked fine on another cybertruck at the service center so def affects a few but I can't be the only one.

Most people don't use 240v tools so doubt they notice it but should check it as I do believe it affects the other systems: I've seen weird things where car won't charge at certain charge levels but driving it around kicks it out of this and then it works fine.

Specifically, I plug in a charger, it won't charge from the App or on the car - I made a video of this. I unplug it and replug it and still doesn't charge. I unplug it and plug it into a model y and the y charges fine. I plug it back into the truck it doesn't charge. I drive the truck for 10 mins then come back and it charges fine now - looked again some specific battery config caused it not to charge. Again this was hard to reproduce so I just let it slide but if I can reproduce it then of course that needs to be fixed also.

My theory is it was a bad battery (since it says HV Battery A264 error on the screen) that wouldn't discharge eg at 80% charge it was drawing a little from all the batteries and one bad one wasn't working hence cause for greater concern on reliability of truck in general but of course I also just need the outlet to work.

You seem to know a lot about the truck wiring so maybe ask Tesla for a job so you can go fix it? The service guy couldn't figure it out so they had to call engineering and engineering told them to check every wire which also seems like bad sign.

Again it works some of the time under very specific repeatible cases so doubt it's wiring but I let them do their job and hope they fix it.

I don't pretend to know anything other than it doesn't work and I paid for something that should work.

I am an engineer, I have a rough knowledge of the Cybertruck systems. This is not a common (I don't think anyone else has ever mentioned it) issue, which suggests that it is isolated to that specific vehicle.
The techs and Service Center are doing exactly what they should be doing. They've just to give the engineers a little time to digest it.
Responses like "check the wires" are indeed an indication that it is not an obvious issue, but there are many weird things that checking the wire have fixed.

It does suck to be you, without your vehicle. I think that I saw that you had a loaner, so they are trying to help you out.

And the fact that they have already started the buyback suggests that your case has been escalated to the top. High enough that it got moved over to engineering.

The fix is probably going to be trivial and once fixed, it should be fixed and nothing to worry about anymore.

I'd just try to be as nice as possible and let Tesla try to make some lemonade for you.

I'll test mine tomorrow

The 240v outlet works by changing the high voltage from the traction battery into AC (inverting part of the wave form) and shifting down to the right voltage.

The thing is; that can go wrong if there's something wrong with the wiring, the inverter, or the transformer. And if you feed various voltages into it - such as a weird specific voltage from the traction battery - that can fool a sensor or even just stop working properly.

Either way, this isn't denying you use of the vehicle, and the thirty days are thirty days it's denied your use because it's in the shop. If it's just waiting on the parts and is safe and drivable in the interim, that doesn't really count for the lemon law.

But if you want to lemon it, you do you. I wouldn't letter of the law to stop you.

If it's in the shop that's considered towards the 30 days. Until they say it's fixed it's going to stay in the shop. You might want it to be different for some weird Tesla fan boy reason but that doesn't change the law.

I'm completely fine letting the arbitrator decide that and if they say Tesla owes me nothing so be it.

Better question is why they don't they just give me a different truck or at least give me a working Cybertruck loaner? Both of those would lessen the pain of paying $110k for a FS cybertruck that is not in my possession but they got my money + I pay hefty insurance on it.

Interestingly, note the following verbiage: https://bbbnp-bbbp-stf-use1-01.s3.a...summaries/wa-ll-summary.pdf?sfvrsn=6d66b64f_2

1) The new motor vehicle is out-of-service by reason of diagnosis or repair of one or more nonconformities for a cumulative total of 30 calendar days, at least 15 of them during the period of the applicable manufacturer’s written warranty;

2) Where a manufacturer repurchases a vehicle solely due to days out of service, “the number of miles that the vehicle traveled directly attributable to use by the consumer” is limited to the period between the original purchase/in-service date and the date of the 15th cumulative calendar day out of service.

3) The dealer must provide to the consumer, after each time the consumer’s vehicle is returned from being diagnosed or repaired under the warranty, a fully itemized, legible statement or repair order indicating the diagnosis made and all work performed on the vehicle, including but not limited to a general description of the problem reported by the consumer or an identification of the defect or condition, parts and labor, the date and odometer reading when the vehicle was submitted for repair, and the date when the vehicle was made available to the consumer.

4) Substantially impair means to render the new motor vehicle unreliable, or unsafe for ordinary use, or to diminish the resale value of the new motor vehicle below the average resale value for comparable vehicles. -> are you saying non working outlet is going be above the average resale value for a comparable vehicle?

5) A vehicle is “subject to diagnosis or repair” when a consumer presents the vehicle for warranty service at a service and repair facility authorized by the manufacturer or to which the manufacturer or authorized facility has directed the consumer to obtain warranty service. A vehicle has not been “subject to diagnosis or repair” if the consumer refuses to allow the facility to attempt or complete a recommended warranty repair, or demands return of the vehicle before an attempt to diagnose or repair can be completed. The eligibility period and the 30-day out of service period are extended by any time that repair services are not available to the consumer as a direct result of a strike, war, invasion, fire, flood or other natural disaster

-> so bad idea to pick up the car before repair is completed

Also no need to argue on dates, Tesla will provide the date it was submitted and date it was made available. Bet it was in the shop that report is going to have day in and day out.

Notice also (1) states just by sitting in the shop >30 days it is a lemon. No other definitions needed. This encourages manufactures not to use the "we're too busy" excuse which is only fair. Notice (2) states as soon as the 15th day passes, doesn't matter how many miles you put on it, they can't deduct mileage past the 15th day -> gives them incentive to not to take more than 15 days to repair which they already have.

I'd have nothing to complain about if they just gave me a Cybertruck loaner. Instead they made me drop it off, wait a week+ each time before they even looked at it.

I'm not being a Tesla fan boy, I'm just telling you what the law means. It doesn't mean 'you waited a month for a part'. There's an actual meaning, and it means you were deprived of your vehicle for the thirty days. You're just refusing to drive it. That's going to be something that you'll have to argue in court.

Like I said, you do you. I wouldn't resist. But Tesla might. Your lawyer might charge you more. I don't know. You do you.

-Crissa

PS, below average. Average - that means including all the trucks that are banged up by their users. Your truck is otherwise unused, with a problem still covered by warranty.

Sorry but appears someone failed high school reading comprehension so didn't get into Harvard law school...

WTF is wrong with you?

You're doing everything backwards. Even your replies are backwards.

It doesn't take law school to know what 'average' means. You should know that by what, fourth grade?

Not going to hire you as my lawyer is all I need to say...

Clearly you didn't notice I wouldn't want you as a client.

You've exceeded your sympathy, I'm sorry.
