Today while I was driving suddenly the BCI malfunction light came ON. I had to turn the engine off and fire it up again to make it go away. Anyone have this come up? Not sure why it popped up. Backup camera and sonar is functional.
What should I google when looking for this switch?My OEM lasted a month or so after I cleaned the contacts in the brake switch then started having issues...put my replacement switch in a couple weeks ago and all is well again. I took the OEM switch apart and cleaned the contacts again (black soot was on them again) put it back together and put it in the glovebox as a backup. Looks like it’s just going to be an ongoing issue but I’m out of warranty so at least I know what the problem is and I can fix it very easily.
I just bought a 2017 Armada Platinum and just yesterday I got this error. I was just sitting in the parking lot with truck running and the dash went crazy.We just bought a 2017 Nissan Armada last month. Today my wife tried to start it and it wouldn’t start for about 5 minutes. Once it finally started the BCI Malfunction warning light turned on along with other lights. I searched the issue and found this thread. After reading the thread I’m a bit panicked. I called the dealership and they said they’ve never heard of the BCI Malfunction. Which was not good news to hear. Since you’ve all been through this issue, what do I need to tell the dealership to look for when diagnosing and fixing this issue?
The part number for the switch off the Murano I used was 25320-AX00B (niles). But now it supersedes to 25320-AX10A (valeo). which is the new part number you’ll get and is the switch everyone is having issues with. Get an aftermarket brand like back/arnley, Holstein, Vemo and etc. use 25320-AX00B on rock auto’s website part search and you’ll get a list of aftermarket manufacturers for this switch. but don’t get the OEM Nissan or you’ll run into trouble again.My first suggestion is MAKE the dealer fix it if you're still under warranty.
If you're not under warranty, read through the last 5 pages of this thread.
There are part numbers that myself and others have used/bought for replacements that have seemed to fix the problem.
Just a few days ago there was a member that found another Nissan switch that didn't have any issues, but also fit the Armada. @Bravosser got a part number?
There was also mention of a TSB that required a computer re-flash. It's not really a huge problem, just annoying until you get it figured out.
The dealer not being able to figure it out would not be acceptable to me. I would escalate that to Nissan USA.
Bci malfunction light came while driving it home from dealership! I couldnt believe it and it has come on everytime I've driven it..I've owned it for a week, it has 40k. Dealer said it's probably the wiring harnass for front sensors. Others say brake switch.
Yes have them read this post lol. Service advisorS don’t like to be corrected or customer telling them what’s wrong with the car. All u can say is you read about this issue online and it’s always the brake light switch and it’s a big issue with the OEM switch. My issue was fixed by using an older style switch from a junk yard car. The new OEM switch they are using is junk. They are easy to change so just keep a spare in your glove compartment.I'm betting the dealers going to argue with me about it and do what they want.. any chance of me having any input?
Are they cheap enough and easy to do where it wouldn't be worth my time to take it to a dealer? My closest nissan is about 45 minutes away..Yes have them read this post lol.

Yea OEM switches go for like 60 bucks. Aftermarket on rock auto go for like around under 40 bucks.Are they cheap enough and easy to do where it wouldn't be worth my time to take it to a dealer? My closest nissan is about 45 minutes away..
I just bought a 2017 Armada Platinum and just yesterday I got this error. I was just sitting in the parking lot with truck running and the dash went crazy.
I turned the truck off then it didn’t want to restart....after a min or so it started. I got that error like 3 more times the same day.
I was afraid to turn the car off of being stranded somewhere.
I must say last weekend I towed a U-Haul trailer..... and the brakes seemed like they were bucking.... should I have disabled the bci function???
My 2017 Armada has spent 13 days over 3 visits in the Nissan shop, trying to solve the BCI Malfunction issues many people have. Like others, power would drop, cruise control would kick out randomly etc.. On first visit to Nissan they reprogrammed the antilock braking computer - didn't help. On the second visit, they replaced the Brake Light Switch - didn't help. On the 3rd visit, they dug deeper than just their diagnostic tool, and discovered that when they disconnected my trailer brake controller, the problems went away. Fingers crossed, that has been the problem. I'm going to drive it a while without the controller, and if all is well, I'll have a new trailer brake controller installed. Nissan does not furnish that accessory, so you have to go 3rd party. Anyway, thought I'd share this in case others may want to try this simple, do it your self solution to BCI Malfunction. Good luck!I just bought a 2017 Armada Platinum and just yesterday I got this error. I was just sitting in the parking lot with truck running and the dash went crazy.

Iam having the same problem took mine in today said they couldn't find anything. Wanted to keep it today but told them they couldn't because it was my wife only transportation for work. Gonna rent a car next week and take it back to see if they can find out what the issue is. 2018 Nissian Armada platinumThis issue for me has been ongoing since I had the vehicle. Left me stranded with the car not starting. Dealer had my car 4 times changed the battery the first time... second the brake switch... 3rd time said the brake switch they replaced must have been bad. Now they 4th just flew in a master mechanic from Nissian to look This chronic problem who said since he cannot replicate the problem he cannot suggests any repairs... 20 min after my case owner at Nissian North america calls me to tell me this the dealer calls me and says we found the issue it’s the ABS control assembly... however Nissian will not fix this under warranty for me and it’s a $4,500 job.... part number suggested by Nissian is 46007-5ZA9C... I have read in this thread that this did not fix someone else issue. I have called a lawer sounds like enough folks here having Same issue and I am sure there are more out there. maybe class action suit is they way to go. I just got my car back last week after Nissian had if for almost a month and I just replicated the problem in less then a week. Car won’t start will have Nissian come tow this POS and hopefully do the right thing and fix what they believe the issue is. My take on it is Nissian knows there is an issue but is turning their heads because the fix must be expensive and a recall could cost them a lot of money to fix the real problem.
How did they fix it??The dealer repaired it under warranty, all good
What I am seeing indicates that 25320-AX10A is the new part that replaced 2532--AX003.Guys looks like nissan must’ve finally figured it out it’s their crappy brake switch! The OEM valeo 25320-AX10A has now been replaced by The new OEM 25320-AX00E! Looks like I’m gonna order one and try it out, and hopefully not use a 13 year old switch.
No. In Nissan terms “replaced” is pretty much meaning superseded. That’s the old number.What I am seeing indicates that 25320-AX10A is the new part that replaced 2532--AX003.
