There is a brand new TSB (Technical Service Bulletin) Mazda Dealer advice for ALL CX-60's sold in Europe and UK.

TSB NUMBER: R003/23 Dated February 22nd, 2023.

All (some) CX-60's made from the Start of cars Production up to the DECEMBER 22nd 2022 Production Date in Japan.

From VIN Number (Last 6 Digits) 100001 To VIN 123074.

There are Separate CAUSES with two Separate VIN Number ranges:

THE CAUSE:

Cause 1. VIN 100001 To VIN 123074 DECEMBER 22nd 2022 Production.
[Cars with Driver Personalization System].
If the push button start is pressed multiple times in a short period of time without having completed the driver recognition by the driver personalization system before, the vehicle systems may not go to sleep mode even after the ignition is turned off.

Cause 2. VIN 100001 To VIN 108896 AUGUST 29th 2022 Production.
B. [All CX-60 vehicles]
Due to the improper control software of the Electrical Supply Unit (ESU),
the vehicle systems may not go into sleep mode even after the ignition is turned off.

Therefore BECAUSE the car is not going into sleep mode (or off) a parasitic draw down of your cars Batteries
electrical capacity occurs and basically flattens your CX-60 car battery.

THE FIX:

A reprogramming of the cars BCM (Body Control Module) and the cars ESU (Electrical Supply Unit)
with your Mazda Dealers in house and online MDARS (Mazda Diagnostics and Repair Software) Application.

Both modules have since been modified with updated Software during current Mazda Japan production, but
for the current owners within the above VINS the cars MUST BE Software updated @ your Mazda Dealer with MDARS.

There are no parts to be renewed, ONLY the Software Update that can ONLY be done by your selling Mazda Dealer Service Department and ONLY applies to cars with the above issue.

I post this information to HELP Mazda owners, this is very new and most Dealers would not be aware of such a TSB,
IF you wish to inform your Dealer please be polite and tell them the TSB Number and Date and repair procedure with MDARS.

You 'may' get a Service Advisor telling you this was done in your last Service, well obviously IF you are still having this issue then politely tell them this TSB is all new and has not been available to Dealers before as a known software fix.
Either ask your Dealer if it can be done in next Service, Or if you are having immediate issues with Battery Drain, ask if car can be booked in for this fix under warranty ASAP.

Again, I want to stress Mazda Japan likes the Customer to complain to the Dealer of a particular issue, unfortunately some Dealers still don't run MDARS for updates during Service unless owner complains of an issue.

I would politely says that If you are experiencing this problem with your cars battery after only a few hours of your car parking with a dash warning of low battery charge signal when you go to start car then you should tell your Dealer of this complaint ASAP, remember Mazda and or your Dealer will not perform a fix unless you have a problem, so
advise them you are experiencing low battery charge warnings on dash.

Cause 1. VIN 100001 To VIN 123074 up to DECEMBER 22nd 2022.
For BCM reprogramming (vehicles with Driver Personalization System only):
The BCM is software updated with MDARS Dealer programming application.

Cause 2. VIN 100001 To VIN 108896 up to AUGUST 29th 2022.
For ESU Reprogramming (All Vehicles):
The ESU is software updated with MDARS Dealer programming application.

BCM Calibration File numbers are available to Dealer in Bulletin and vary on cars with PHEV or except PHEV for
'Main' or 'Sub' File Name.

ESU Calibration File name KR9P-66S07-D for ALL CX-60 Models.

 

[ASH8]

NOTE this TSB was first publicized in January 2023, however,
Another cause has been added with the related sections having been changed accordingly.

OBVIOUSLY If your Mazda Dealer has rectified your Battery Drain issue Before and you are Still experiencing Low Battery Warnings then this Bulletin Does apply to your car and politely inform your Mazda Dealer that new causes have been found and are now rectified, can you book my car in as the Battery drain issue persists.

 

[Burli81]

Thank you very much for the information!

 

[Southeastern]

Yup this happens to me, I thought I had left the car on when it happened!

but hopefully it wont be an issue on the diesel, so not bothering getting any further issues fixed on my PHEV as all being well, it will be gone by mid April and will be someones problem.

Hi, where do you get access to thees TSBs?

Sometimes it is better not to ask too many questions

Why don’t you expect this being an issue on the diesel? As far as I know it’s draining the 12V battery, not the high voltage one.

I’m quite surprised by this kind of assumptions for the diesel being less troublesome than the PHEV, but I would not be so sure. It may come from the dealers trying to keep the sales going by, as the PHEV is getting bad reputation from owners comments.

Sure you will not have low electrical range issues, nor noise between 50-70kmh from the rear drive shaft on the front drive diesel. But most issues could be common to all CX-60’s.

My dealer tried to persuade me to go for the diesel. I hope I don’t regret ignoring him and getting the PHEV! Time will tell…

Its not the 12v battery.

I drove the AWD Diesel yesterday, and boy, its such a better car. I am glad to be handing back the PHEV keys next week in exchange.

Will I be wrong to do this? Absolutely not. Will the diesels have issues also - possibly/probably, but at least I have the better car (imo) to work from as a base.

I love it with a new poster comes on with big statements when don't even own a CX60

Sorry, I thought it was the 12V battery (one of them) as I read about a few cases about those getting low as well. I have not received my CX-60 yet, you are right, but I’ve been reading a few forums for the last 2 months.

Half of the CX-60 issues are not specific to the engine, but production quality, software bugs and chassis tuning. So I would not expect the diesel to be way better in these aspects than a PHEV manufactured today. Time will tell…

The PHEV uses entirely different engine, software, gearbox automation, etc etc, nothing is comparable in the running gear. Chassis tuning is better due to reduced weight, anyone who understands cars and how they handle will know, lighter is better in the most simplistic language.

I do not have expectation bias, I know full well there may be teething problems with the diesel also, however the diesel has been out in Japan for a lot longer than the PHEV has, and it is more simplistic in the way it operates, therefore it will on paper be a better car because its a tried and tested setup, not 'new' technology. I'll be as blunt in my review and comments of the Diesel as I have been about the PHEV, I hold no loyalty to a brand.

Just FYI, the PHEV cars manufactured today are the same cars as those manufactured yesterday, nothing has been changed on a manufacturing level, albeit some basic software changes (that have still not ironed out all the bugs) and a suspension change. The PHEV was released a year too early and their depreciation is mega in the UK due to this.

In six-cylinder engine is augmented by a small M-Hybrid Boost electric motor sandwiched between it and the standard eight-speed automatic transmission, same setup identic in PHEV, just smaller in R6.
Lots of improvements reported by dealers, are incorporated into the production line every 3 months.

Yes as i said above different software, engine and gearbox automation, and your last point is incorrect however if you have evidence to ai substantiate that claim im more than happy to see it.

Just to disprove your theory Daniel, my brand new diesel has not had the door sound proofing done and Ill know what else hasn't been done next week.

 

[BWJ]

Every CX-60 is equipped with an 8-speed automatic gearbox with a multi-plate clutch and integrated electric motor/generator which replaces hydraulic converter, if you have any information on other matters, that do not appear in our online Mazda Technical Information about gearboxes not being identical, let's finally hear about it here, so even MAZDA can learn something from you.

Diesel and PHEV is not the same production line, agree ??

You didnt understand my post Daniel, its ok, its not the first time you haven't but I respect English is not your first language.

 

[Southeastern]

Ok so just to add to that, the two PHEVs that came on the same transporter as my diesel to my dealer didnt have the sound proofing either. The Technician remarked he had five cars to do that week with an eyeroll over its tedious nature.

 

[BWJ]

Just to make it clear, sound proofing is not a "factory defect" but a desire of some customers.

There is a service bulletin fir it and a mandatory on the dealer PDI, therefore, Mazda see it as a defect, whether you do or don’t is irrelevant.

Yes, the components of the systems are the same but cooperation between them are much more simplier in diesel (easier for software, automation etc).

No, they don’t see it as a defect, I asked Mazda if they are or will be incorporating the sound proofing mat on the production line and they literally said it was not a defect, but just an improvement for unsatisfied clients. Same about the shock absorbers.
