I am thinking to upgrade my MX 2017 MCU1 to MCU2. I think it costs around $3k+tax. I know that current Tesla's are using MCU3. Does anyone know if Tesla will ever offer a MUC1 to MCU3 upgrade?

Just took delivery of a Model 3 dual motor 10 days ago. Apart from this frustrating issue the car drives really well. I hope a key fob comes out soon.

If we consider money in the bank then yes your right since savings interest rates are so low. However even in a low/moderate risk diversified investment you would average 5% return per annum on average across a 20 year period. So when you consider opportunity costs geothermal does not make sense...

Actually my initial preferance was to have HVAC powered by geothermal. However geothermal is costing $80k ($40k in extra material and $40 for drilling the wells) more than the next best alternative. Based on the size of the house etc this worked out to a payback period of 20 years which does not...

So living in Canada we get extreme winters with temperatures as low as -40 celcius so it takes a while for the battery to warm up and this of course uses more range. I am due to start construction of a new house and have the option to heat the garage using hydronic underfloor heating. Of course...

I have an S70D and recently after driving for 2 hours in heavy rain my brakes failed to work twice within a period of 4mins after i got off the highway. Thank god the roads were empty. Tesla service checked the brakes and did not find anything abnormal. I am thinking due to regenerative braking...

Yes, twice for an hour and once for 30mins.

Once the battery is warm you lose 35 to 40% range at -25 celcius temperature

Yes, i think it is important for everyone to know the effect on range with such cold weather to help plan better

Yes, on a long trip with highway driving it makes sense that you experienced a range loss of 35%. Due to stopping and starting i lost 65%.

The tire pressure were only slightly off.

101.8km is what i drove. When i arrived to supercharge i had 30km rated range left which equates to about 10km.

Model S 70D So it is -25 celcius (-35 with wind chill). I started out with a cold battery from my garage with 337km rated range. I drove local and highway during the day and the actual range was only 115km. This equates to a range loss of 66%. Driving style was generally slow acceleration due...

S70D May 2015 90% is between 330km and 337km

Could you have swithed off autopilot without realising? The logs should be able to confirm this.
