Sticky Steering

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 ?

Very common issue now the cars are ageing , seeing it more and more.

Mazdas usual line of 'we have never heard of that before' has become a thing of comedy with this car :) Its like they don't understand the internet exists and folks chat..

Sadly, like the humming propshaft, the TSB does not always fix it, hopefully you'll be on of the lucky ones and it resolves after the action is performed.

How sad it is that Mazda is ignoring their customers as if they are a bunch of stupid idiots. Totally respectless and above all: a very very dumb way of killing the Mazda brand history.
Their top and middle level management should be fired right away to save Mazda's reputation.

As I said in another post I've got the exact same problem.My steering rack was already changed in July and now I'm waiting for another change, but the problem is that a new/modified steering rack will arrive in Europe in mid November ( according to Mazda ).Good thing is that meanwhile my dealer gave me replacement car until then because I didn't want to drive my car because IMO it was unsafe.
I have to praise my dealer for their professionalism and approach to my problem on this occasion

My car developed this problem like a week ago and 13 700km after. The steering is sticky and you have to apply some force to get the wheel turning and then it suddenly rotates too much which makes the car not so fun to drive. I think I have to contact my dealer again and think they will only laugh at me. Haven't even read about these problems before I noticed them by myself so there is clearly something wrong. Now I wish I spent my 65k€ for something else.

Sticky steering is occurring in large numbers in Japan as well, and due to a backlog of steering gearboxes, delivery times have been extended to 2 to 3 months. As an emergency measure, lift the car up and turn the steering wheel lock-to-lock several times at high speed, and the problem will improve for about a week. Lock-to-lock when in contact with the ground is less effective because it cannot rotate at high speed.

I thought I had gotten away with this one, but mine has developed this issue too in the last week.

When you drive a two hour drive on a single carriage country road, it really is quite laborious trying to steer with the sticking and over correcting because of it, and the steering not self centering.

We have seen a lot happening in the UK owners club in the alst few weeks, has to be connected to the damp and cold or rain, due to the mini storms we have had.

I wonder if rather can be the issue of mileage or cumulative number of turns. What mileage is of yours?

Our friend @chero.60 mention a temporary partial remedy by lifting the car and then hard turning of the steering wheel.
Interestingly, some Honda owners report that their issue resolved itself after changing the tires (which incidentally requires both lifting the car and very often turning the steering wheel to full stop —for inspection/service of brake pads once wheels are off). Probably not a coincidence.

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...

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?

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.

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

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.
