BMW iX Seat Heaters Fail: Owner Seeks Fix & Cost Info

Hey there! I actually faced a similar issue with my 2020 BMW i4 last winter. The heating mat in my driver's seat was malfunctioning the same way, barely any heat and unusual shutoffs. The diagnostic showed a faulty heating element and a damaged wire connection in the seat assembly. The repair wasn't just a quick fix, they had to remove the entire seat cover and replace the heating mat system. It was quite a serious job since they needed to disassemble most of the seat. They also found that moisture had gotten into the connection points, which contributed to the failure. The work took about a day and was covered under warranty in my case. Given that your iX is still pretty new, you might be in the same boat warranty-wise. I'd suggest going directly to a BMW certified service center for this one, these heating systems are pretty complex in the newer electric models. Just a heads up, when they fix it, make sure they test both the high and low settings thoroughly before you take the car back. Hope this helps!

Thanks so much for sharing your experience! Really helpful to hear from someone who went through the same thing. Quick follow-up, do you remember roughly how much they quoted for the repair before they found out it was under warranty? Also, has everything been working smoothly since they fixed it? Wondering if I should expect any other issues to pop up.

Hey again! Glad I could help earlier! Since you asked, actually had the work done last week and everything's working perfectly now. The seat heater kicks in right away and stays on until I turn it off, just like it should. Such a relief, especially since I was worried it might be a bigger issue. About the cost, before I found out it was going to be a warranty job, they quoted me 390 € for the whole repair, which included the new heating mat and all the labor for taking the seat apart and putting it back together. Pretty fair price considering the amount of work involved, if you ask me. Haven't had a single problem since the repair. The techs really knew what they were doing, they even showed me the old heating mat and explained what went wrong. My advice? If your car's still under warranty, get it checked out ASAP. These things usually don't fix themselves, and you might as well get it done while it's covered. Let me know if you need anything else, happy to share more details about my experience!

Thanks again for all the details! I actually bit the bullet and took it to a certified BMW service center yesterday. You were spot on about the heating mat, that's exactly what they found wrong with mine. What a difference going to the right place makes! The technician was super knowledgeable and walked me through everything. Just like in your case, they had to take apart the whole seat, but they got it done in about 6 hours. Best part? It was fully covered under warranty since my car's still pretty new. Picked it up this morning and tested it on my way home, working perfectly now! The heat comes on strong and stays consistent, just like when it was new. Really glad I didn't put this off any longer. Definitely learned my lesson about going to certified dealers for these newer electric models. Thanks again for giving me the confidence to get this sorted out. Really appreciate your help!
