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 ?

I have a CX-60 from march 23 and it just started showing this problem with a bit over 15000 kms.
It had been running smoothly until now but last week I was on a 300kms road trip and it started having this sticky steering, I was a bit tired and it was raining so I thought it could be just my fgeeling but I had it again on the way back and also the cruise control and self-correcting system is acting abruptly when adjusting direction.
I'm glad I found this thread with more people reporting the same problem as I was getting frustrated about how difficult it was becoming to drive the vehicle.

It’s strange how it just ‘comes on’.
Mine is fine (albeit its far too heavy weighting and resistance when turning) for about an hour and then goes sticky.
I’d have thought it would always be like that once its happened once
For me it has been barely gone since it appeared, I always notice it there sooner rather than later when I start driving, definitely it doesn't take an hour for me to notice it.

It's more resistance for me now. It's not possible to drive now with single hand.

Genuine question.......could it be a software issue?
Then again, I suppose, why would software programming have a different affect on different cars? I.e. some encounter the issue, others don't (at least, not yet)?

I wonder if it is related to the viscosity of the lubricant and its thermal usage limits?
Could it even possibly be the lubricant becoming congealed and causing more friction?
You see many things from electronics to chemicals that have a working temperature range, though I find lubricants usually have a threshold in the minus Celsius range, which we have not reached in the UK yet.

I would be surprised if that's the case. When it happened to me the temp. was mild and I would expect resistance but not this resistance that it is suddenly released when I push, it is more like blocked and the freed when. you reach a level of pressure... with that kind of viscosity, I would expect it to be sticky all the way.
It is a problem that Mazda have accepted. I have just brought my car back from the dealer as they await the new steering box as the part supply date is unknown.
I actually managed to speak to Mazda direct asking why the new box was needed as it seems a lot of work when no real investigation as to why the problem exists. I was told without question there is no danger with the vehicle but a new modified box needs to be fitted as nothing can be done to improve the current sticky feel.
I will update when the part arrives and has been fitted.

I hope that a revised steering rack and associated parts are the fix and I would hope selfishly that the production line is getting the new parts first that why this delay exists for vehicles currently on the road. I say that because I placed my order for a CX-60 in early October and I still haven't got a build slot allocated.

CX-60 (KH) - Resistance when turning Steering Wheel
TSB NUMBER: R062/23 EU/UK
Aust/NZ Unknown Status.
DESCRIPTION
Some vehicles may exhibit resistance when turning steering wheel.
CAUSE
The worm wheel and the worm gear may deform, resulting in resistance increase.
MASS PRODUCTION CHANGE
The shape of worm wheel teeth was changed.
SUBJECT VIN & PRODUCTION DATE RANGE
CX-60 (KH)
REPAIR PROCEDURE
Replace the steering gear with a new one referring to workshop manual “STEERING GEAR AND LINKAGE REMOVAL/INSTALLATION”.
PARTS INFORMATION
[R]: Replacement parts
This TSB was revised from Sept 4th original issue, not a lot of new info apart from requesting Dealers to check front wheel alignment.
As my other life was a Mazda Part Manager for many years EPCs/Books/PCs are my bible for anything Mazda from a parts point of view and what it can tell one if they know how to look, sadly too many current gen Dealers are not old school and would not know what the interchangeability code are (about 6) in association with parts and the parts modifications and interchangeability.
In regard to CX-60 Steering Rake there is no new news, the Part Numbers have not changed between EPC or this TSB as shown above. BUT might change once new parts supply has landed, Usually there is some additional Letter on the end of part number to prove the change.
Here is EPC lists for RHD and LHD CX-60.

Clearly there was a bad batch from their supplier as normally Steering Gears are very reliable.

I have got VIN 131xxx (out of range of this TSB) and also have got this problem. Do you think is it possible that I have got old, not modified steering gear?
if your is broken too, they have to fix it. But your case would be an indication for a bigger issue and not just a bad batch.I received my car the 1st of march, 2023 and it enterd production at the end of 2022, so I understand it is affected by this, right?
Its affected if the problem happens for you. If it dosent, its not, like every other issue.

In Japan, sticky steering occurs even in vehicles equipped with K616-32-110A. Replacing the gearbox probably won't be a permanent solution.
True, what I meant was if it is officially affected from the range of affected vehicles in the TSB.
I have the problem and I guess it will be easier to talk about it to the dealer now that it is officially recognized by the company.
