1. Steering wheel off axis by about 10*.
2. Horn essentially inoperable (unless you hit very specific parts of the horn with all of your might). This almost led to an accident as someone veered into our lane on the way to service.
3. Missing and pulled stitches in the center arm rest.
4. Internet NOT working. Oddly the internet browser was NOT working at all unless we reset the car (holding top buttons on the steering) and only then it would work transiently for a while.
5. Iphone app intermittently showing that it could not connect to the car and that we have no Tesla products registered
6. Difficulty with the automatic open and close for garage that worked about 5/10 times.
7. Rain sensing wipers don't actually sense rain and need to be manually turned on for the system to realize there is rain ie not functioning normally.
8. This was VERY bothersome. The falcon door closes and rests on our second row seat in the area of the shoulder rest so now the leather is creased and has a very nice carbon fiber imprint on it--ONLY on the passenger side so it appears to be missaligned. My concern is that the door is going to start ripping apart the leather.
9. This vanity one is just annoying, but we can't do the Christmas easter egg feature without it failing about 10 seconds in.
I have had my X since December and it has had a few minor issues fixed by the service centre.
I was quite worried before ordering it, but it has be no worse than any recent car.
My previous car was a Range Rover Sport, then 2 X5s before that and an Audi before that. I also have a 911.
I often remark that I would love a Lexus for the reliability and no hassle ownership experience, but certainly when I have driven the RX I have found it terminally dull to drive, and ultimately it is a car and I want to drive. Actually as a brand Lexus to me has been going backwards for some time and it is disappointing as more choice of good cars to buy would be a good thing.
On the other hand our previous car, the current model Range Rover Sport was a dream. I was very concerned about reliability but it seems much improved. Over my ownership it required the tailgate to be realigned and the mirrors to be reset, both done during annual service. As for material quality and a general feeling of luxury inside, I feel that Range Rover have surpassed the Mercedes S Class to be the nicest mass produced cars to sit inside.
Thus when people discuss reliability and quality on Tesla's I feel that many things get confused. Reliability wise it seems that it is very unusual for a Tesla to actually break down and strand the owner. Electric motors are inherently very reliable, so by this definition reliability is good.
When you think of the various gadgets on a car then that is another matter. Let's call this functionality, which is where many of the OP's issues seem to be.
Then there is material quality. Much as the Tesla is not as plush as my Range Rover was I find it quite acceptable and similar to other SUVs such as the Q7 or the XC90. Some areas are better, some worse.
Looking at the above list, most things seem easily fixed or just annoyances.
1. Funnily enough my steering wheel had a squeak which was fixed and now appears very slightly off centre. Clearly 10 degrees off centre would be annoying, but should be easily fixed.
2. This seems exaggerated. I use the horn babe once a month. Nearly always due to annoyance with someone else. I can't really think not having a horn would have been a safety issue more than a couple of times in the last 10 years.
3. Annoying but an easy fix.
4. I have never used the browser in the car. It is clearly a gimmick not designed to be used. Use your phone. Much as it is a function that isn't working well, I think the level of annoyance has to be linked to how useful it wold have been if it did work.
5. Definitely annoying and something that is more useful so you'd rather have working.
6. A gimmick again. I am guessing that every other car you have had just allowed manual opening and closing and assume that its still available.
7. Yup they don't work well at all. I always have to resort to manually hitting the end of the stalk which is annoying but no big deal.
8. Annoying, but ultimately Tesla's problem not yours and has not effect on the ability to use the car. If the door rips your seat they will have to give you a new seat. I suspect that the upholstery is more robust than you are thinking. It seems more likely that the seat is misaligned as surely the door cannot be that misaligned. Service centre should fix though.
9. Another gimmick that I don't plan to use. If a kid was hiding the door open button to make the doors flap I would give them a telling off. I know Tesla made it available so you would like to use it, but it has zero impact on your ability to use the car as a car.
Net net you have a few things that should be fixed by the service centre relatively easily and have no impact on your ability to use the car.
The things that do impact your ability to use the car are the app and bluetooth issue. I don't know if they are due to the new MCU.
I must say the answer from the service centre on the iPhones seems like BS. Some are too new and some are too old. I'd have told him in no uncertain terms that I am not a moron if he came out with that. As someone else said how the service centre deals with things has a big impaction your ownership. I had a few squeaks that needed fixed when the car was new and a door about 1 or 2mm out of alignment. That was it. Not only did they fix these in one service visit, but they gave me an explanation of ow they fixed them, something no other car has ever given me. Indeed other manufacturers have been good at fixing mechanical issues but awful at fixing rattles and squeaks.
Of all the cars I have had the Audi was the least reliable and had by far the worst dealer, Porsche is next least reliable. That was perhaps a local issue, the BMW and Range Rover dealer have been excellent. This makes a real difference and I think this may have added to your disappointment.
But ultimately is your dad enjoying driving and using the car. I like to drive it and enjoy the amount of space inside compared to my last car. A few rarely used features being unreliable wouldn't upset me much and I certainly wouldn't;t care what other people had to say about it. Take them for a drive in it hen see what they say.
Is you dad upset or does he enjoy it? I just ordered my parents a new BMW, I spent ages deciding what was important for them in owning a car. Then I gave them a list of cars to look at. They didn't pick the one I thought best met their needs, but its their car so that's the one I ordered. I would certainly have been worried that someone who had owned Lexus for 20 years liked the Lexus experience and it was risky to get them a car clearly likely to have more faults.
