We picked up our Model X 90D Friday (VIN 17xx) and needless to say it has been a wonderful experience overall. This is our first Tesla! I would like to share some initial thoughts and concerns here and I welcome the forum to give me feedback and tips. 1. For those of you wondering. Yes the rear spoiler is active on the 90D despite DS said its not. I can tell pretty clearly that it has at least two positions: fully expended at low speed and partially extended at freeway speed. Also I think we received a 2" full size hitch in the truck (super heavy) when the accessory hitch option was free at the time we placed the MX order. 2. The windshield. Absolutely loving it. It's such a wonderful feature that MX has. All I can say is that after driving the MX, it's hard to sit in another car because your eye vision will feel so much more boxed-in with other cars. The sun glare has not been a problem for us as the top of the car is coated pretty dark and blocks most of the heat from the sunlight. 3. The FWD. Loving the utility. It makes getting in and out of 2nd and 3rd row like a breathe, much like a mini-van when its a SUV. No problem with the FWD and front door function so far. However, I did notice that the sensor seem to pickup person standing next to the front door where it should not be interfering the FWD opening. The door will therefore opens lower and closer when its not necessary. My only concern is that it takes rather strong force to trigger the safety stop on the FWD. This could potentially be safety hazard if someone, especially kids, are in the way of closing. Finger hazard is dangerous too with the mechanical opening and closing. 4. 7-seat option. While we had some concerns after reading so many comments on the forum about the 7-seat option to be too enclosed for the 3rd row and blocks rear view mirror, we have not regretted our choice. Two points to be made here. First, the cargo space for the MX is rather limited when compared to a mini-van and full-size SUV. So if we are going for an extended road trip, we need all the cargo space we can get by folding down the 3rd row. The 5 seats remaining has much better utility than 4 seats if we had chosen the 6-seat option. Secondly, the storage space for the 2nd row is rather limited as well (no seat back pockets). My kids sits in the 2nd row would enjoy having the center seat as convenient space for backpacks, books etc. And with a bench on the 2nd row, its also a good option if anyone wants to take a nap. The rear view mirror is limited mainly due to the aerodynamic body shape and hatch back. With or without the 7th seat don't seem to matter that much. I have since learned to look at the front screen for any blind spot vehicles during lane change. 5. Real world range. We have only driven about 150 miles over the weekend. The real world range appears to be a lot lower than the EPA estimate. This is in contrast to the RAV4 EV we have. We were getting about 120 miles range on the RAV with 95 miles stated EPA range. For the MX, the best energy use we had with mixed local/freeway driving was about 360Wh/mile which translates to 2.78miles/kWh. On the RAV we are getting 3.2miles/kWh consistently. And coming from the RAV, we have learned to be gentle on the accelerator and breaks and watch speed more carefully on the freeway. Considering that MX is much larger and heavier, I'm not entirely surprised. So we have not regretted spending extra to get the 90kWh battery. I would think even with the now increased 75kWh of the base MX, the utility still seems to favor larger battery packs. 6. Booster seat. We had some trouble installing the booster seats on the 2nd row. We have Clek Olli backless booster and it was very hard to install it. The rounded hugging shape of the MX seat-backs while very comfortable seem to interfere with the armrest of the Clek seat. You have to push the seat really hard against the seat-backs in order for the latch to reach the connector. And it was impossible to fit a seat protector underneath. With the seat protector, it was not able to latch properly. So we had to install without seat protector. Also the seat belt buckle on the 2nd row sits flat with the seat and does not extend up like most other cars. With the booster installed, it was very hard for the kids to buckle in. A seat belt buckle extender would solve this. But we have not needed it with other cars. 7. 3rd row access. When I tested the function it was quickly noticeable that the seat position of the 2nd row does not go back to the previous position. I read other comments on this forum that this problem was supposedly fixed in the new software update. My test still showing it is not. The only case I found it will go back to previous position is when both 2nd row and 3rd row are occupied. Even if 2nd row is not occupied and 3rd row is, it will still squash your ankle when moving back to position. The other point is that my kids sit in the 2nd row and like to move their seat forward to be able to reach doom lights (if only they would move the doom lights of the 2nd row closer to the seat than it is right now!). It would be super nice if Tesla would add a software option to always recover to previous position regardless of weather seats are occupied or not. 8. Wifi connection. The wifi connection of the car could be improved. Our garage has poorer Wifi signal. While the iPhone is showing 2 bar connection, the Tesla is showing only one bar. Opening the Testla app, it took much longer to connect to the car (several seconds or longer) with the Wifi on. The main problem is when the car arrives on the driveway. It will pick up house Wifi signal but the connection is not actually being made. So opening the Tesla app and it will take forever to connect to the car and most times simply times out. This makes Summon impossible. To solve this I have to manually disable wifi but the car does not retain the settings on startup. So in the end I had to delete Wifi settings so that it will connect to LTE at all times in order to get swift response from Tesla app. Note that where the car cannot make Wifi connection, my iphone picks up Wifi signal fine. 9. Regenerative breaking. I think Tesla has different regenerative breaking mechanism than all other cars. The regenerative breaking is so strong in Tesla that the slow down is simply huge if you lift the feet off the accelerator. Even with the low Regenerative Break settings, the break is rather strong. So you basically have to keep your feet on the accelerator most of the time while rarely using the break pedal unless you absolutely want to stop. This takes a while to get use to as common sense when you see break lights in the front is to lift the accelerator and put your feet on the break as well. Most other EVs as I have heard, ex. the RAV4 EV, behaves more like conventional car where the regenerative breaking is on the break pedal. 10. I miss AM radio on the MX.
