Booked in for dealer to check seems to be sticking on a little too long on one side causing car to lurch can be quite bad at times but feel it's more apparent when on hills than flat, I'm guessing that's just due to weight transfer during release,l'm interested if anyone else has had this problem or knows what the issue is.
-
ok been in today, control module requires changing part on order, they had a vehicle in the day before with same issue but affecting opposite side so not first time fault.
-
Control module changed out took about 1 1/2 hrs, centre console required removing, seems to have fixed the fault, handbrake release much faster and not holding on whilst clutch bite is occurring. Dealership took a video during process this seems to be the next new thing in customer service.
-
Had exactly the same issue, handbrake does seem to come off (light goes out) but drivers side rear brake does not disengage, as you say only happens when you pull away a bit quicker or on a hill. Garage were a bit skeptical until I physically showed them the issue and then tried to re-create it in one of their cars, which of course I couldn't. Booked in for a fix next week so we will see what they do.

Mazda are aware of the problem they have issued a notice bulletin, don't get fobbed off, you will require the same course of action. Ours is now not only sorted but better than when we took delivery of the car ( new ) ?

Thanks think I will give the garage a call, they told me on Sunday that there was not notice bulletin. But then they also told me that you have to take the hand brake off manually!!
-
Yes that's what we did operate manually till it went in to be fixed, not nice operating it in auto when it shunts car as it did.

Hi,
The TPMS warning has come on several times over the past week but no problems with the tyre pressure.
Yesterday whilst pulling away from traffic lights the electronic handbrake also failed to release properly. It felt to release on one side sooner than the other. I did notice a post lower down from someone who has had a similar problem, thing is it did it a couple of times and then it was ok.
I have just booked it into the dealers for them to check it, they seem to think that the pads are sticking and need replacing. something I doubt as it is a 2016 CX5 with 10k on the clock, a mixture of motorway and town driving.
There was mention in the other post of a Technical service bulletin from Mazda about this fault, I can't find it online.
Has anyone else had the same problem and how was it resolved?
TIA Cheers, Colin

A new caliper, brake pad set, seal kit and replacement disc is what you need to fix it properly!

Thank you for that kiakid2, I shall print the bulletin and take it to the dealers!
-
I mentioned at the last service at the end of July that the EPB was sticking on a bit on my car when pulling away sometimes. I couldn't say if it was affecting one side more than the other, just that the car wouldn't move off when it should. They checked it out and told me about the TSB prescribing new rear callipers. They were fitted on Monday this week. Early days but the problem hasn't re-occurred yet. Fingers crossed!
-
Thanks for that Ant, my dealer has not been that helpful, after kiakid2 posted the TSB I followed it up.
I phoned Mazda UK, Customer services checked with the Technical department, they confirmed that our car fell into the category and more than likely this was the fault. Customer services said that the dealership would probably have the parts needed in stock as they should be also aware of the TSB.
I then phoned my dealership back and explained everything to them, they were not interested. They said that I have to take the car in, they have to diagnose the problem. Make a report, take photo's and send this to Mazda who then decide if it's warranty. They are not willing to pre order the parts as they say that they will be charged and have to keep them if not needed. This statement I do not believe from my past experiences, I have emailed Mazda UK just to check.
It looks like a trip to the dealers on Saturday, they want the car all morning to diagnose the problem, no doubt I will then have to re-book it in once they have ordered the parts and spend another day without the car.
It wouldn't be so bad but the car is only 18 month old, 10k on the clock. It's been in on 4 times for issues with the infotainment system, updates and a new module. then we had the boot struts replaced, now brake issues.
I just think dealerships should be a little more helpful, at the end of the day they are not doing it for free, Mazda will be paying the bill.
-
I agree about dealers being more helpful. Surely its common sense that if you keep a customer happy, they are far more likely to return and spend another bunch of money on a car with you? I know they don't like warranty work as the margins are much less and they make little, if anything out of it.
I managed to coincide the checks for all of my warranty issues (3 now, headlamps, tailgate struts and rear brakes) with service visits - none of them were serious enough to warrant a separate visit (although I had to return for the actual work on the headlamps and brakes to be done as they didn't have the parts in stock). I'm also lucky that the dealership is only about a mile from where I work so I drop the car off and walk to the office.
I think the TSB for the brakes specifies some checks that they need to do to diagnose the problem which I guess is why they want the car in first before agreeing the work.

seems to be a worrying trend for me, with more than a single problem with the EHB system. for ours it was obvious that one side was failing to release immediately resulting in quite a violent lurch when EHB operates. still ok for now but have been few times when you can just tell they don't both release at the same time.
-
Well, I took the car into the dealers, they carried out tests and diagnostics and the results. There is a problem with the electronic handbrake not releasing but they can't find any problems with the TPMS.
I again went through the TSB that kiakid2 had provided, I also explained to the dealer that from the information that I had gathered from the forum that TPMS actuation maybe linked to the handbrake fault.
Either way he didn't seem too happy to be told what the issues may be, they have completed a report along with photos and sent it off to Mazda, I now await the outcome!

This seems to be a common problem, I ditched my last dealer partly because of this. They really don't like it when you know more than they do. I had a 6 week argument with them after they repaired the car from a rear impact over a clicking noise form the wheel. I told them several times that it was the wheel bearing, but they wouldn't listen. I even timed the noise relative to the road speed and did the calculation that proved it was happening once per wheel revolution (Yes, I'm that sad...). They changed it in the end and the noise went away.

Spoke to the dealer today,
1 x disc
1 x caliper
1 x set of new pads
On the way from Mazda, booked in for next week so hopefully sorted. Only thing that bothers me is that if one is faulty then surely there is a high chance of the other side failing. Maybe Mazda are hoping that the car is out of warranty before it does!
Thank you for the advice anyway!

Mine makes a bit of a sueal, as if it hasn't quite released. Is this part of the same problem ?

Hi,
I Have 2016 CX-5 Diesel Sport Nav and previously experienced rear near side brake "dragging". After some to and fro at the dealer, I eventually had the brake control module replaced in Feb 2017 along with new pads, disk and calipers. The repair instantly alleviated the dragging situation, however, after approximately 8 months trouble free, I too am now experiencing an intermittent squeal/whine/rubbing noise when pulling off from a situation where the handbrake or hill brake has just been engaged. The hand-brake appears to be dis-engaging correctly but the noise is suggesting that I may have to get back to the dealer and try to recreate an intermittent fault which of course never happens. If anyone has had anything similar, I would be interested to hear how you are getting on with it. Thanks.

This has reared its ugly head once more at 9000miles, car used daily, rear passenger side not releasing quick enough. been told its a "overheating calliper" I guess seized and waiting on arrival of 2 new callipers to go with new sat nav unit :'( will update once car has been in
-
Both rear callipers replaced under warranty on the 2016 model
-
Reared its ugly head once more……....Yes mine again, despite having the rear L/H calliper /disc replaced in June I have endured the occasional lurch to one side as the handbrake releases, for the last six months since I bought the car.
A week ago the rear R/H calliper decided to seize up and cook the disc, setting of the TPMS. Fortunately I was able to pull over quite quickly and sit for fifteen minutes or so to let things cool down.
Since then the handbrake has behaved impeccably with no lurching at all when released, so now I am worried that when it goes in to the dealers they find nothing wrong!
