Cost?
Considering the exchange rate $3500 would be a fairer price. Also they should be offering it cheaper to cars under warranty to save themselves costs when MCU1 inevitably fails$4000 for the MCU upgrade, HW3 upgrade was already included in FSD purchase.
You should ask them for two prices - one for the MCU upgrade now & one for it after the current MCU is fixed. If they have half a brain, they’ll give you a discount on $4K nowHi, At a shade over 70K Kms (and almost the 4 year mark (4 years next Feb) our Tesla MX is off the road at the SC awaiting a remanufactured (ie new chip) TEGRA daughterboard. MCU etc. I hadn't been onto the forum for a while and really hadn't paid attention to the issue that sounds like it is hitting a lot of cars in the US at around the 70K Km (45K mile) mark and that means the early MXs from now on too. This was after the centre console completely failed and then the car became only intermittently driveable (you can drive with no centre console with only basic driver functions - just like an old petrol car - even creep forward when the brake is off stops working). However, after 48 hours of that the car stays in "car off" mode more and more - even with charge (nearly 200Kms left) and even when you do resets. Using the key (which does still work) to lock and unlock while inside the vehicle and manually opening and closing the drivers door eventually (and I mean 10 mins of trying) got the car into driveable mode and I then drove straight to the SC before it failed again as I seriously thought it would need to be towed out of our driveway if I let the car shut down again! The SC staff were very helpful and friendly! Not sure at this point how long we will wait for the replacement part, but the lesson is that as soon as the centre console fails and won't restart (and it will restart once or twice but then goes completely a few days later), get it to your SC and don't wait until you literally can't drive the car.
Get a price?Thanks for the suggestion. Having been happy with it the way it was, I hadn't been thinking about the upgrade, but you're right - and the locals have a brain when head office allows, so worth asking.
It doesn't render the car undriveable. The main instrument cluster still works, with blinkers and gear changes, charge level and status etc.A fault that could render the car undriveable suddenly with little warning is potentially grounds for a safety recall. They should at a minimum allow pre-emptive replacement of MCU1 in cars with high mileage. IMO, IANAL and all that.
Yes, I'm just so surprised when I get into the car and the screen is responsive and it just works. It has been so longHad the MCU upgrade done yesterday ... what a difference! It's so smooth & responsive compared to the original, and so many great new features!
Hi, That's not a regular thing/price. We have seen it reported twice that two different owners got a discount, but we don't know why their SC granted them the discount. We asked the two owners. They don't know either. It was the Las Vegas SC.It was rumoured that a failing MCU1 could be replaced with a MCU2 for U$1900 in USA.
I am hoping we get a similar offer here.
The car lost app connectivity and central screen on the Monday evening about 9pm (the app couldn't connect and so kept showing the location of the car at that time - I was driving home from our local supermarket). We drove it in basic mode (not sure the official name) on the Tuesday and Wednesday as I thought we could survive till the Friday when we had it booked in for a service - I hadn't been aware of the MCU issue prior and assumed we had a software bug, not a hardware failure. The service booked some weeks prior scheduled for the Friday was not for this, but to complete a service from pre-covid that had been waiting on a suspension part which was squeaking, but not a safety issue. I'd booked it in now because our lockdown has ended and we are open again and locally covid free (except for the odd inbound arrival hotel quarantine case). On the Thursday morning (so only 60 or so hours after the central screen dropped) the car would not start. My wife tried to get it to start, but gave up after 10 mins and took our other car. I then spent quite a while in two separate attempts at lunchtime and mid afternoon, finally got the MX to power up (as I described above) and then headed straight to the SC. So yes, it was not a lot more than 48 hours from loss of central screen to very hard to get started. They gave me an ICE loaner as I needed a car the following week (hence scheduling the service prior to that week) and it was then the following Thursday (so 7 days) before they had it fixed - as they needed to ship the part in.Experiences differ. The poster above said 48 hours to an almost complete lockup. Hope I'm one of the lucky ones - my MS is my only car, and I know Tesla's legendary "just-in-time" ordering strategy...
I’m guessing that it is reading a number of bad sectors on your flash drive beyond a limit set by Tesla and issuing a warning.So, I downloaded 2020.48.12.1 and now have this message? Coincidently, I'm booked into to have upgrade to MCU2 in a few days.
Does this message mean MCU1 is now maxed out - faulty?View attachment 621084
