We have a 2026 CX-90 in which the instrument cluster will randomly on turn all the possible warning lights while driving. The speedometer section will go blank as well. A second or two later, the speedometer will come back on and the other gauges will drop to zero for a second or two and then everything is normal. It is at the dealership now where they've been working on it but I was curious is anyone is seeing this issue and if it has been resolved permanently.

 

Welcome to the forum

 

That is a warranty concern, and you should go to MAZDA service department and attempt to correct it yourself.
You BCM or ECU may have a communication problem.

The only safe thing you can do that will not affect your WARRANTY is go and have your battery load tested. No matter the age of the battery, don't assume anything about its condition until you get it correctly checked. measuring the voltage will not indicate it state of health.
Just because you have a 2026 new vehcle does not mean that battery is ok. The battery itself may be over a year old or may have been discharged for various reason on the dealership lot and fast charged. This is not an uncommon occurrence and has happened for decades all the way back to the 1970s or older.

The other reason to go to Mazda is that your concern will go into your VIN history. This is a good thing for you because if Mazda corrects the issue and it returns you will have a record of having reported it and supposedly was corrected?

As for anyone else having the issue I m sure there may have been similar reports. Currently I just checked the TSB Data base and there are no TSB for your year and model relating directly for that issue as you explained it.

 

Yes, I am having this same issue with my 2026 CX-90!
it is pretty alarming, though at this point, it doesn’t seem to go further than what you’ve described. Power brakes/steering, are maintained. Lights & radio stay on too.
I also get a single pass of the front wipers when it happens.
1st service visit they blamed my USB cord b/c it had an adaptor & told me to get an apple cord.
I left the service center & within 1 mile, nothing plugged in, it happened again.
it happened at least 20 times to me. But sometimes I’ll go a few days with it not happening!
I have another service visit scheduled tomorrow.
The service center did tell me one other person has had this issue locally- & that person is filing a lemon law claim.
Car is 6 weeks old. Under 3k miles. Insane.

 

I bought a 2026 CX-90 about 6 weeks ago and just started having this issue! Going to call dealership since it?s a little alarming.

 

I'm sorry you are experiencing the issue too. If it makes you feel any better, so is our loaner CX-90. That being said, our service center worked with Mazda tech support who told them to change the dash cluster which is what they'll be doing to ours and hopefully resolve the issue. Although, I'm not sure how that controls the wipers but who knows. What frustrates me the most is all the electronics making the car "smarter" without adding a way to diagnose a problem effectively. Imagine how much this would cost if it wasn't under warrantly ant an hourly rate. I would expect that they'd be able to put a sniffer-like device to capture all the communications between the devices and figure out if something isn't sending an expected signal, if the receiving device isn't receiving the signal, or misinterpreting the signal. I would think that the behaviour of the dash cluster would be to display a warring light for anything which it didn't get the proper signal to indicate an issue but I'm not a mechanic.
I would recommend you start a ticket with Mazda Corporate as well (Look for the email us link near the bottom center of https://www.mazdausa.com/contact-us page) so they can assist along the way by expediting parts or working with the service center.

 

@missmichaela87@yahoo.com And annoying since they aren't cheap vehicles.

 

I was watching a video from someone else who still had the problem even after replacement parts. She ended up getting the vehicle switched out. Hopefully that?s not the case for us! She bought her cx-90 in November and brought it in Feb-March. This my first Mazda, so all very new to me.

 

I would not GUESS or SPECULATE that your concern is the same. If it where you would be at least an experienced mechanic?

Your Mazda is well within the warranty, and you should be going to Mazda instead of DIY and members guessing and assuming that your claims as the same as other is accurate or even true based only on your observation.

This is how inaccurate information starts on the internet and model specific threads on forums. Instead use your warranty and have Mazda solve your specific issues and then return and state what Mazda did to solve your concern!

My response goes to other reading this as well and not just on a specific platform but falls into any auto manufacture, think before you assume that you issues read like yours.
At least use common sense..
Are the same exact model and trim
Are the used very basic perimeters at least close to the same i.e.:

Same engine?
Same transmission?
approx. close to the same miles on the odometer?
All the service schedules done on time?
Similar operating environments?

 

No you are not and no your dont know how the change of service is done at a Mazda dealership!
You wait for your dealership to at least look for the complaint. You don't start a direct contact to Mazda because this WILL slow your process down. They will now determine through contacting the dealership what plan of action to take. Until them you will not either get your Mazda service faster or they may determine that you might been to go to another dealership or leave your Mazda and get a loaner.
So NO starting 2 service contact at early stages of an issues slows you getting a resolve in a timely manor. Just remember there is no legal time period within reason for a dealership or any auto manufacture to take care of a warranty issue only that they do in a reasonable time. Attitude is everything when you approach any service if you are pushy don't expect to get the red carpet treatment.

Any member reading his advice you been cautioned...

This person reminds me of a kid that his father said no for something so he runs to Mom not stating that dad already said NO.... ROLMAO
