I have the same problem with my CX3 2015 out of Warranty contacted Mazda Australia they told me to take it to Mazda dealer which I did two weeks ago, They inspected and told me the fee to inspect and tell me what I already knew that the seat belts on both sides will not retracted which is a safety issue as now cannot have any passenger in the back and being family car creates a problem. The dealer then wanted to charge me $1500 to replace both seat belts. I said a bit expensive which should be a recall issue they said they would contact Mazda Australia and get back to me so far no one has done this how much longer should I wait and do you think they will cover the costs????

Now all fixed thank you Sue for your help, Mazda where very good took a little while but pleased with the result except for my car inside coming back with heaps of mud and dirtier than when it went
in to be fixed but at lease the safety issue has been done and can now use the back of my car for passengers when we get out of lockdown. Glad I have been able to keep my Mazda as
quite attached to it best car for running around in and parking.

I have the same problem with both my rear seat belts in my Mazda CX-3. My mechanic said to try contacting my local Mazda dealer but because my car is out of warranty they said there’s nothing they can do as they class it as general wear and tear and want to charge me to get them replaced. I see it as a safety issue and feel it should be recalled given how many posts I’ve just read of the same problem. There’s probably more people out there with the same issue. Any ideas on how I can take this further?

I recommend as many people as possible report this issue at this website:

Report an unsafe product

Realised @Biscuitboys that this is the thread I was meaning to post on!

For all others, I posted this reply on anther thread in the hope that others with the same issue would read and be able to use my experience as leverage or just gain insight into how to go about fixing the same issue. Biscuitboys informed me they're having so much trouble over in WA, so it seems as if there is no united front for Mazda HO Australia wide.

Anyone in NSW see below my experience:

Our 2015 CX3 was purchased secondhand in 2016 and was out of warranty. With just the two of us we never really used the backseat belts until recently dropping a relative home, he came to find he couldn't use either of the back seat belts. One was locked in, the other extended out and would not retract. After googling and finding this thread by chance, we rang Mazda to book an inspection for the fault (cost to us of about $180)

Within an hr they had inspected and agreed it was a fault and they would replace both belt units at no cost to us.
The following week we had an appointment to do the repair and it was completed within the day.

FYI this is Ryde Mazda Service centre NSW.

We were both apprehensive as to how it was going to go, but it honestly could not have gone any smoother. I don't know for sure, but it did honestly seem like it was something they were aware of and we were just another CX3 that had the issue. We didn't have to argue or explain our case at all.

I really hope anyone in the same boat find they have the same great experience as us, and aren't made to pay for a problem that really does seem to be an issue with the make.

Hi All,

First time poster and a bit of a long time lurker.

I have been having an issue with my rear seat belts for a few months but now have come to a problem.

Originally when I would have people in my back seats the seat belt's......either side didn't seem to matter, would stay some what elongated after use for hours or even a day on the worst case then would slowly recline and be back to normal. As I don't have people in my back seat all that often this wasn't too much of an issue just annoying.

Now just over a week ago I had 2 people in my back seat and have got an issue, One seat belt never reclined and is now locked fully extended as the passenger wasn't sure what was going on then yanked it all the way out on his way out and it is locked in place even if I try feed it back in slowly.......It was go back in but if you pull it just all comes out again and never reclines. The other seat belt is having the same issue as previous but now doesn't fully recline it still has slack in it (more so then usual). I have searched high and low and am unsure if this is some sort of easy fix that I cannot figure out? I have read about the autolocking for the baby seat but cannot see how to unlock it etc.

Is there something I am missing that will unlock my seat belt? I can't seem to fix either of them. The other thing is how do I get the back compartments where the seat belt mechanism is held apart so I can look at the mechanism and inspect any damage? I don't want to go to my dealer just yet as they charge arm's and legs so want to attempt to fix myself before going to them.

Thanks in Advance,
Brendan

Hi I have spoken to Seat Belt solutions, they have informed me that there has been an on going problem with the Mazda rear seat belts. Mazda needs to recall all the vehicles or at least replace them when one has an issue free of charge.

First time posting, have been watching this thread over time though. Mazda garage in Malmö SE asked for 750€ for replacing both (out of warranty). Made a deep feel and sound study of the action of the mechanism. So: A carefully applied drop of thin oil or two on either side of the belt drum (belt fully rolled out) is enough to fix it. Just did it on our CX-3. Works like a dream. One needs to take the whole thing off. Perhaps I am above average when it comes to fiddling with vehicles - but anyone can do this. Ambient temp above 15°C is recommended to preserve the plastic interior bits.

Hi everyone,

I did the same as Kent, but that did not suffice in my case. Additionally, I had to wind up the tensioner spring to almost max (which is a kinda tricky job, BTW).
It has worked, but the seatbelt retraction is still not too impressive, which leads me to the conclusion that the tensioner spring was just not dimensioned correctly in the first place. I had exactly the same problem in my 2007 Miata, so apparently Mazda has not learned too much in the years in between.

 

[tictac2ow2]

I have the same problem with my CX-3, the rear seat belts are both not retracting.

 

[milliechan70]

One of my rear ones has just done the same thing. My car is 5 years old but this seems like a major safety issue to me. I've never had this problem in any other car and I've even had vintage ones. I am worried this failure could happen in an accident to the other seat belts. Will contact Mazda and let you know what they say.

One of my rear seatbelts has just done the same thing. 2016 CX3 as well. Will call the dealer

 

[Joy]

When my seatbelts would not retract on my CX3 2016 it to me was a safety issue it was also out of warranty
so I took it to my local Mazda dealer who charged for looking at the problem but this fee was waived and
new seatbelts were installed after they contacted Mazda Head Office so it is worth getting it looked at.

 

[michellehall]

I had my 2016 CX-3 rear left seatbelt replaced out of warranty in 2021 and now about 2 weeks ago the rear right seatbelt has failed. I have taken to my Mazda dealer and they quoted me $854 to replace! When I said I had the other replaced free of charge, they then said 'oh we can contact Mazda to see if they will cover it out of warranty'. Surely this should be a safety recall with quite a few people posting the same problem here.

 

[paippo88]

Same problem on the rear belt, I got stuck and can't pull. I will contact mazda I will let you know what they tell me, in Italy.

You're lucky only $854, they quoted us $1000 for each side for the rear belts, at Mazda in Parramatta. The warranty finished in 2020 and they wouldn't fix it out of warranty. Never going back to Mazda again.

 

[simon]

Did anyone have any luck having mazda fix this out of warranty? My 2016 cx3 has just done this exact thing and has been out of warranty for a year...

They would fix it but not out of warranty, and they wanted us to pay over $1000 for each side.

I followed the advice that was posted by Sterlo #7 on this thread on Oct 2, 2022.
Faulty seat belts
The problem is caused by bad alignment of the pre-tensioner.

 

[JimboJr]

I have a Mazda cx3 2015 model and is out of warranty.
just found out have the same problem with the rear seat belts.

This is a common problem with the vehicle safety system so Mazda should have repaired all vehicles under a recall, regardless of the warranty.
You can try to escalate the issue with Mazda to have the seat belts replaced.
If you are OK with DIY or you know a good mechanic then you will find the problem is caused bad alignment of the pre-tensioner mechanism which is mounted on the side of the retract mechanism.
The problem is explained in detail it you go to this other forum link and read posting #7 by Sterlo.

WD40. Use the long tube to poke inside by the side of the reel and give it a squirt. Mine reeled back after a couple of tugs.

 

[SVD123]

I visited this thread in Feb this year when the rear seat belt in my 2016 MAZDA 2 failed to retract. The car was bought second hand and was out of warranty but was a work car previously (barely used) and I never use the back seat. Read this thread after being quoted $850+ by my local mechanic and they made an off comment about this being a known issue with Mazdas.

Late Feb, booked in with Mazda dealer for an inspection hoping they'd fix it free of charge but willing to pay the fee. During the email and phone call I flagged mutliple times the identified issue and mentioned it seems to be a 'known' fault. Took screenshots of this forum ready to argue if need be. Wasn't needed they quickly agreed on the fault, and ended up waiving the inspection fee AND replacing it free of charge.

Hi Brenden My name is Birendra.I have 2015 CX-3 Mazda as well. I bought from first lady owner and she did mention that the back seats were never used. I didnt check rear seat belts when buying and never thought of seat belts issue ever. Same issue as yours-full released never retracts. I opened the mechanism and found after bit of mucking around that the problem is with the spring inside has lost its tension. If spring works normal then belt will be retracted easily and get reset each time. An still trying to see what I can do.
