r/BMWX3

Hello,

So I’ve had my mind made up, already have a deal lined up to trade my Kona N in for an x3 M40I.

This is due to needing awd aswell as more space since I have my first kiddo coming in 2 months, I have had my mind made on getting this x3 as I seen a yt video and car seat fits fine, but the more I read on here the more I see that really isn’t the case if you are on the taller side, I am 6’1 and my wife is 5’8.

How usable is the vehicle at these heights with rear facing car seats? I’d love to get the car and it’s a great deal but if I’m going to want to sell it in 6 months cuz we are crammed up I’ll save my money and look elsewhere.

Hi,

Today my 200,000 mile MY 2013 X3 xDrive35i reported "Drivetrain Malfunction. Drive moderately. Maximum drivetrain output not available." Scanning via BimmerLink revealed the following faults:

12 Digital Motor Electronics, 2 errors
* 133B04: Valvetronic system: no adjustment possible
* 133E10: Valvetronic system: deactivated, too frequent adjustment errors

The eccentric shaft, valvetronic motor, and eccentric shaft sensor were replaced at 170,000 and then again at 180,000 miles. For the past 1,000 miles or so we've heard what sounds like some misfiring via the exhaust system - a repeated, bassy, "thump thump thump" sound every now and then.

What do you think is the issue? Thank you.

Have the X3 M40i 718M rims and rears are coming to the end of their life.

Tire shop has a set of 255/35/21 PSASs, can they be put on the 718Ms as a square setup?

I got this car in May 2025 after being a Honda driver for many years. I wanted more upscale, smaller but still SUV. I loved how it drove and how comfy it was so I bought it. After a few weeks I realized how awful the glitchy technology was and how distracting and confusing it was as well! Nothing was intuitive. The “upgraded” Harmon Kardon was sub-par. The car has a mind of its own.. you open the door to get something and the accessory turns on and the car has a 15 min dance party in your garage. It’s ridiculous. So, I’m going for a Jeep Grand Cherokee Limited. Wonder if anyone else has had similar experience and what you switched to instead?

TLDR; iphone 16 pro max disconnects from bmw carplay every time i use voice dictate, and will not reconnect unless i reboot my car’s computer system.

hi all.
i have a brand new 2026 bmw x3.

the first time i had this problem was literally driving off the lot the first day i owned it. it took 3 months to realize what was causing it. please let me know if anyone has any kind of experience with this because nobody knows what to do with me.

My BMW and iPhone 16 Pro Max are connected via carplay.
while driving if I park or at a red light, want to respond to a text message and I click the voice dictation button on my iPhone in any app, 1 of 3 things will happen:

1. whatever I’m trying to dictate is written out and duplicated 500 times. then my carplay crashes and it disconnects from my phone. bmw will then be unable to reconnect to my phone. The only way to get my phone to reconnect is to delete my phone from my device devices in my car., delete my BMW Bluetooth from my iPhone, and hold the power button on my car to reboot idrive. this often happens when I’m in the middle of driving, which causes me to have to pull over and reset my car bevause then i can’t see my map!!
2. Voice dictation will not glitch and Will properly write whatever I’m trying to dictate, but my phone will still disconnect and refuse to reconnect.
3. Sometimes nothing happens and it works. But that’s rare.

I can’t just not use voice dictation. I’m paying a lot of money for this car and this seems ridiculous to have to just accept and get over.

when I have had my car serviced the loaner cars they have given me have not had this issue and nobody else that I know with a BMW has this issue so it is clearly a problem with my car.

however, the service department doesn’t know what to do with me. Who should I reach out to?

Hello, I’m searching for a X3 M40I and was hoping to get opinions on this one locally available to me. Does the price seem fair for the mileage and the packages included on it or what’s a more reasonable price to offer! Looking for 22-24.

Hey everyone! I’m new to the BMW family, it’s been almost a month with my X3 and I’m absolutely loving it so far! I’ve already put around 1,000 miles on it in my first month.
One thing I’ve noticed is that when I’m driving in the city, all times after driving just 1 mile, the estimated gas range drops by 2–3 miles. This happens even when I’m driving carefully and staying under 30 mph.
Is this normal/expected with the X3? I understand the range is just an estimate based on driving conditions and recent fuel economy, but I wanted to see if other X3 owners notice the same thing.
Thanks!

In my new BMW X3 2026 with the Premium Package and the Driving Assistant Professional Package, how can I find the highways on which the hands-free Driving Assistant Pro works? I cannot find it in the settings of the BMW Navigation app in iDrive 9. How can I check if the car is actually equipped with Driving Assistant Professional to activate it?

I was scrolling through the settings on my 2020 X3 M40i (iDrive 7) and noticed the “Engine Sound” option.

It’s currently on “Depending on driving mode.” Curious what actually changes mechanically if I set it to “Sporty” full time. Is it purely ASD through the speakers, or does it also affect the exhaust valve behavior?

Anyone know for sure?
