A few reasons. I was actually one of the first to take delivery in the US. In fact I drove the car for about 8 months before I even saw another one on the road. Anyway, the BMW IX was promised(and still is) to be like Tesla in that any new features can be upgraded via software. When I picked up the car, self parking was supposed to be a feature coming soon. When it was finally available for a $250 upgrade, I was told that the "head unit" on my car was too old and could not upgraded via software! I wasn't the only one that had this problem too. That was the start of it. I had also recently purchased a Model 3 and love the tech. In fact it made me realize how far behind BMW was with Tech. No Dog mode. I have a golden and had to go through a whole process to set the AC,,,which would only stay on for a little while. Even simple things like screen clean mode and car wash mode don't exist on the BMW. It baffles me that BMW has 10 years to look and copy these features but didn't ....The one place where the IX shines however is the ride quality and sound. It is as close to silent (even at 85 MPH) as I have ever seen in any car. No shudder during fast take offs, no high pitch whine. Silent!! The nail in coffin was charging infrastructure. I live10 mins from 2 different Electrify America Stations which are the main ones to use for CCCS DC. They were constantly down or broken. Even shortly after they were upgraded to 350 HYPER chargers. EA usually only builds about 4-6 in any location. I took a 3000 mile trip last October and this pattern was the same almost everywhere with broken or poor charging speeds. To make matters worse, the EA app(which integrates with BMW,,,,,sort of) was never accurate in terms of occupied/ avail / broken chargers. In fact the EV app on the iPhone showed different data than the BMW did most times. Very poor network and integration. I live in a high rise so home charging is not a feasible solution right now. The car was recalled about 4 months after I owned it for a battery issue. The car was in the shop about 45 days. I decided to Lemon Law it (I have a lot of experience with the process). When I got the car back, the process takes about 1 year or so. Originally I wanted a replacement IX. However, when the model X prices started to tank, I took another look the model X and got in at the lowest price (so far). I did have my eyes wide open in terms of build quality and suspension, road noise. Im getting used to it but will probably higher somebody to sound insulate it. For anybody who might think that the Model is quiet and has a fine tuned suspension,,,they have not driven the BMW IX also with air suspension,,,,it truly is night and day and one of the few things I miss so much about my IX. (Like having a quiet conversion on the highway)...So far the build quality on my X is good,,,no squeaks or rattles. It all came down to me setting realistic expectations. For me, this car was not worth $140K,,,,but when the price came down to $79,000, It made it easier to live with some of the shortfalls in quality and road noise. Overall though, Im really happy with the car. It's new and different, since having the IX for nearly 2 years. I hope this helps in making your decision.
