My CX-60 suddenly developed sticky/notchy steering about 6 months in. ( purchased Dec 2022 ). I have seen other reports of this. Basically the steering will not move smoothly, you have to apply pressure then suddenly it moves, which at high speeds results in having to constantly correct the steering to try and stay in a straight line. First time into the dealer they said they couldn;t find anything. Second time updated steering module ( which turned out to be just software ) which fixed it for 3 weeks, and now it's back in. The dealer is saying they're not aware of other people with fault, Mazda are saying it's not a known issue. However having read other posts for sure other people have the same. It's due in again next week. Anyone else got similar ?

that dosent seem to ve the case in the UK, we are seeing all sorts of mileage when this crops up. Mine is only on 2500, but others range from 5 up to 15, its literally all happened in the past month or , multiple posts a week in the owners group with the same issue appearing.

According to the NHTSA recall, the CIVIC (FL) steering rack is manufactured by Hitachi Astemo. Although this information is not confirmed, it seems that the steering rack of the CX-60/90 is also made by Hitachi Astemo. If the manufacturing company is the same, there may be some reason there.

Well, well, well...
"Back in March, the same vehicles were reportedly being fixed as part of a Honda service repair due to complaints of “sticky” steering. It's unknown whether the issue is related to the current recall, and it has only led to a regulatory investigation so far."
So this is all about
"Both four-door and five-door Honda Civics are affected by this recall. The automaker will begin reaching out to vehicle owners on December 4th, asking for the cars to be returned to a nearby Honda dealer for an inspection and potential replacement of the power steering rack."
I have just brought my cx60 Feb 2023 to the main it appears to be a component in the steering rack but I will have to wait for parts from Japan, the maintenance person said it has 3 other on order so looks like a common trend

Same problem here (Hungary) after 32K kms.
Had a test drive today with the service guy, he confirmed the problem, and said I am not the 1st one in the country with the same issue.
Strange thing is that problem appears for other users after less kilometres (10K-ish or less) at the same time. Problem might be weather related ?
Replacement part ordered, leadtime is unknown, will take for weeks for sure per the dealer.

My CX60 is under 10000km, the part is ordered but unsure when it is going to arrive to car repair dealership, I'm told its a mechanical part issue and will take at least 8 hours to rectify. When I pressed on will it get worse I was told "I don't know"
Spoke to dealer, the next available slot to go in for diagnostic is...wait for it....18 December!
So if the part is on a 2-3 month backorder ike many UK owners have mentioned, it could be a four month wait for me to get this solved. FOUR MONTHS.
..and I am pretty sure the dealer technician will say 'no fault found' on the 18th December as well...

Now, assuming it is not mileage dependent, let us think which things on an absolute timescale (not car age) happen roughly in parallel for all affected users.
1. Sinking temperatures (autumn/winter)
2. Firmware updates
Anything else?
It ought to be one of these.

I have printed out the content of this forum for the same reason...
but fortunately they were aware of the problem.Ask the service staff for a test drive and they can not say that the problem does not exist!

I have not received any FW upgrade for months, before the problem popped up.

I am not sure whether that is just natural damage control mode or not at this stage: "let's hope it was just a bad batch, let's replace with another one and see" (I've seen that earlier, driver mirror vibration, power train vibration).
Eventually the reason of failure is understood, and the new part is redesigned accordingly. So the 10 dollar question is: does your replacement part have a new part number or not?
And on
I will keep this forum informed of my situation,and update accordingly

The CX-60/90 uses a dual pinion EPS.
It consists of a rack and pinion and an assist motor.
I contacted the manufacturer Mazda, but could not get a clear answer.
The probable cause are:
1. The problem with the rack and pinion itself.
- It is difficult to imagine this because the mechanism has been used for over 50 years.
2. The shape of the motor reducer's worm wheel and gear teeth is poor.
- The combination of worm wheel and gear is old technology and difficult to imagine.
3. Software issues.
- Since the steering wheel is sticky even when the engine is stopped, it seems to be a hardware problem rather than a software problem.
4. Problem with the material of the worm wheel.
- Although it has not been confirmed, the worm wheel may be made of high-performance polyamide PA410, which is 70% plant-based and developed by Royal DSM in the Netherlands, instead of the common polyamide PA66.
- If this is correct, the evaluation period may be too short because the material has just been developed.
5. Lubrication problems.
- Lack of lubrication.
- The physical properties of the lubricating oil are poor.
- Poor temperature characteristics of lubricating oil.
The above is my personal speculation, and the true cause is unknown, but I personally suspect 4 and 5, especially 5.
