2026 Tesla Y Juniper

Strange issue is that sometimes (20%?) the windows won't fully close on locking the car.

It's not 1 specific window - sometimes its a couple, sometimes, just 1, sometimes just front ones, sometimes just back ones.

I've already tried to uncheck the option for that in settings.

I've already went into the service menu and re-calibrated all 4 windows.

Issue persists - anyone else or anything else I should try?

TYIA!

I have a 2021 Model 3 Performance (NCA, ~79 kWh) and drive only 3-5% per day, 3x a week (short trips to the gym). Car sits in a garage plugged in for ~160 hours per week. About once a month I take a longer trip where I charge to 80-100%, discharge almost fully (to 10%), then recharge for the way back and discharge again.

Based on calendar aging research (Keil/Jossen TUM 2016, Werner et al. MDPI 2021, Battery University, and AAKEE's posts on TMC), I've been keeping my daily limit at 50% to minimize high-SoC dwell time. Imbalance via S3XY Knob sits stable around 30 mV.

A local "battery expert" (claims 26 years working with lithium batteries) told me this is "the worst thing I can do" and "guaranteed battery failure, and I should already book an appointment for the Tesla center" because the BMS can't balance at low SoC because it can't see the differences at 50%. His recommendation instead: charge to 80%, let it run down to ~20% over 1-2 weeks of regular use, then plug in and charge back to 80% — repeat. Explicitly NOT daily charging. His analogy: "you wouldn't drive your gas car to the pump every night to add 1-2 liters." When I asked for sources and data, he called Battery University authors "dilettantes who should be institutionalized" and eventually blocked me.

His main technical experience seems to be repairing Lithium packs, and he told me that he is happy to fix my battery once I mess it up with this stupid "50% daily limit" with an "extra charge for being a smartass". His "don't plug in daily" advice also seems to directly contradict the Tesla owner's manual, which explicitly says to leave the car plugged in when not in use.

A lot of the advice I see online tends to agree with the following:

1. use as low daily charge % as you need to get by for your daily trip without going under 20%. So keep it around 50%.

2. Keep it plugged in all the time and charge frequently. Low DoD (depth of discharge) is better for the battery long term and will result in less degradation per mile driven vs. higher DoD and less frequent charging.

3. avoid very low and very high SoC for prolonged periods of time.

So: am I missing something, or is the "80→20% deep cycling, no daily charging" advice basically extrapolated from LFP behavior and old S/X firmware? Anyone with long-term data on low-SoC daily strategy on a 2020+ NCA (or NMC) Tesla?

My goal is to keep degradation to a minimum. I work from home, the car sits in the underground garage, plugged in 24/7 with a 50% daily limit. Can I really mess up my battery this way? I would think that if this would damage the battery long term, Tesla wouldn't allow a 50% limit setting. I'm open to changing my routines if data shows that this is a bad protocol long term, but all research seems to point in the other direction, especially with me doing longer trips around once a month where I charge it up and drain it down.

Hi everyone, I’m looking for advice because this situation has been dragging on for months with almost no real help from the dealership or Tesla support.

I bought a used 2024 Tesla Model Y from DTLA Audi in late January 2026. Since the purchase, I have NOT been able to properly transfer ownership in the Tesla app.

Because of this, I still cannot fully access Tesla ownership features/services tied to the vehicle.

Tesla support says there still appears to be an ownership/lien-related issue attached to the car. The dealership told me payoff processing was handled around March 2026, but the ownership transfer is STILL not resolved months later, which honestly makes no sense to me.

The most frustrating part is:

• the dealership has basically stopped cooperating,
• they keep redirecting me back to the salesperson,
• and I feel like I’m being pushed into solving backend/title issues that should not be my responsibility as the buyer.

Honestly, this feels like buying an iPhone but not having access to the App Store.

I legally purchased the vehicle, I possess the vehicle, and I have the purchase paperwork. I should not be expected to somehow track down or contact the previous owner myself just to resolve internal title/lien system problems.

I already emailed Tesla Finance directly and am currently waiting for a response.

My questions:

• Has anyone dealt with this kind of Tesla ownership transfer nightmare before?
• What actually fixes this situation?
• Is this usually a Tesla backend issue or dealership/title processing issue?
• Should I start speaking with a California consumer protection lawyer at this point?

I’m trying to stay patient and reasonable, but after months of this, it’s becoming extremely frustrating.

Any advice would really help. Thanks.

Looking at a $2700 bill for a car computer malfunction m replacement after less than 5 years owning it. Bought in August 2021 and so 4.75 years just about.

I heard from the rep it’s 1 year parts and labor warranty. (What drove me insane was that there was a $260 diagnostic fee. I can’t believe Tesla charges a diagnostic fee let alone $200+.)

Anyway, curious how long you guys have had experiences with this new computer car replacement. How much longer will it last?

Hello, I currently have a American model y with the nacs charging port. I head that in Europe they have the ccs2 ports on their cars. Is their adapters I can purchase to use my American car when I move to Europe and will the maps and cellular work aswell?

Hi all,

I’m hoping someone can help steer me in the right direction.

I bought a Tesla model Y today. 2023 model RWD model.

The car was advertised as having FSD, all the screenshots show self driving included package in software on the car, when I went to view the car it had it enabled too.

It went into Tesla for a horn repair yesterday as the dealer noticed an issue with the horn on the day I went to view. It’s then been delivered to me today by the dealer, I’ve paid for it etc and gone into settings and the FSD features are gone.

I think they’ve removed it when they’ve sorted the horn as they’ve done a software update on the car too.

As far as I was aware, it was tied to the cars VIN and as I say, the listing said it had FSD and was a huge reason I bought this particular car.

Anyone else had similar and had Tesla rectify it? Or if not, managed to get any money back?

I’m in the UK.

Thanks all!
