I had the same symptom, while highway driving my 2017 MS 90D, a few weeks after the eMMC replacement. I don't remember if I had AC on, but I shifted to N and came to a full stop (at an exit ramp...) after receiving a couple of error messages (driving not possible, front motor deactivated, no...

In the EU (Germany), the practice of charging a "diagnostic fee" during the warranty period was deemed illegal after court trials. Although the court decision applied to some computer repair, and not to cars, the reasoning would apply here as well: The fee obstructs the owner in exercising his...

To my knowledge both side radiators are for for AC cooling only, while the center radiator is for battery cooling. The airflow logic is not that obvious because the side louvres have to close to improve battery cooling over the center radiator (who does not have his own louvres). I don't have an...

Being fluent in the Serbian/Croatian language of Nikola Tesla myself it is correct to say tess-la. The "a" is short, so it is better than usual "tess-lah". Nikola is pronounced with emphasis on the "i".

The answer is... to be found here: It has to do with a actuator which opens/closes the vents for cooling the car/ battery pack. They are tested during the startup-check when you open the car and keep the car aerodynamic. They can make funny noises especially if the car is new or in a quiet...

The data provided is inaccurate. I checked with VIN from my car and it came up with wrong battery size, wrong supercharging, wrong default tires and production year. Also "Autopilot convenience feature" possibly indicates the ability to have this feature but not necessarily that it is included.

@DESinUS Read through ALL your posts and love the well explained first hand view to the most crucial part of buying a Tesla (and more). Appreciate it A LOT and please keep it up. I asked my DeS prior to delivery if I'd be able to upgrade my S90D battery (3/2017 Facelift) to a 100 kW battery and...

I must admit that I can see some reason for this proposal, although I don't like it. In certain quiet situations (calm side streets, main streets far after midnight, basement garages of shopping malls etc.) people stop looking and watching for traffic before they cross a street. They don't...

I remember a post where somebody stated he bought a inventory P100D and got a 15.000,- (or similar) discount after the "Ludricrous" option was removed at the SeC. Hence my first conclusion was that these "3.3s cars" are such downgraded P100D cars to sell cheaper as 100D. Probably I am wrong...

At the recent shareholders meeting Elon stated that battery upgrades are done (?), but that it is not possible to upgrade from the smallest to the biggest battery (presumably from 75 kWh to 100kWh). He also stated that this is also not recommendable for newer cars and one should rather buy a new...

Sorry, I probably simplified too much and should have written "-normally ALWAYS" and "-normally MAYBE" to clarify my assumption was not about a double failure. Of course any failure of the transmission system can occur anytime and you having 4 of them is something really special. But if I...

Simplified answer: If hydraulic brakes fail in an ICE you have a single effective backup (=engine braking) -ALWAYS. In an EV there is a comparable single effective backup (=regen braking) -MAYBE In detail: Engine braking (ICE) or regen braking (EV) is the first means of deceleration, by lifting...

Thanks a lot Dr. Smoke, as this was exactly the helpful information and reassurance I was looking for in this thread. To sum up what I learned: - an AC motor in a runaway mode is quite near to impossible due to a very demanding electric management and double signal feed from the pedal. Hence my...

You would use motor braking and/or turn off the engine on an ICE. Try this with a cold battery as stated and hence no regen available. Not a good idea to rely on. Not exactly. Pretty sure Parking brakes were designed for parking. From Wikipedia: Although sometimes known as an emergency brake...

Sorry if my post gave the impression everything occuring at the same time, -just the opposite was meant: either/or aspects. To put it as simple as possible: What do you do when driving away with a cold battery downhill (which is normal and frequent) and as a single fault hydraulics fail? I would...

Sorry for reviving this discussion, but the OP has touched my concerns quite close. After reading throughout the whole discussion and a little tech research on braking my worries haven't been eliviated a bit. They don't apply exclusively to EV/Tesla, but to classic ICE cars as well, -but less...

I hear that sound sometimes when suddenly Auto braking engages for a second due to wrong AP inputs (overhead signs, in tunnels, adjacent much slower cars). I relate that to the braking system or brake pads and don't worry at all as I relate this to the very quiet car environment.
