Long Term Review - PowerStop Z17 Evolution Plus Ceramic Brake pads - 2nd Gen CX-9

Pack it up pack it in and go to another dealer who is not a scam artist for customer pay. No consumable brake component can cause damage to a brake module. That's just plain moronic and there are laws against voiding a warranty and refusing repair due to aftermarket parts.
 
Virginia has an annual state safety inspection and while the CX-9 was under warranty, I was taking it into the dealership for oil changes.

June 2020 at 40K miles, I had been notified that the rear brakes were reaching the end of their life. I decided to order some upgraded brake pads for the CX-9.

Yesterday (April 2021) at 55K miles, they came off the car; the rear brakes were at the end of their life again. I was notified that they were at their end of life, as I had the car in for a transmission flush and rear differential service.

While they did have similar stopping power as compared to the stock OE pads, 15K miles is a VERY short life for brake pads. I believe the short lifespan is due to their low-dust compound.

I did NOT buy again.

I upgraded to the Z23 Evolution Sport brake pads. We'll see how well these pads wear.

I'm still on the OE rotors. I don't believe that upgrading to crossdrilled/slotted rotors will gain me anything. The brakes can already lock up on dry pavement with the Michelin Defender LTX M/S tires that I have on the CX-9. If I need to replace the rotors on the next go-around, I'll be using blank rotors from a reputable source such as "Raybestos" branded ones from RockAuto.com.


NOTE: The CX-9 is VERY hard on rear brakes for an AWD vehicle. Both times I did brakes, the rear brakes were at end of life while the fronts were still at half life.

I decided to do front and rear brakes at the same time both times to match the brake pad compound as well as for convenience. Owing to the electronic parking brake, it takes about 15 minutes per wheel to do brakes on the 2nd gen CX-9.
I had the same issue the first set of brakes wore out around 50K and they said need new rotors and pads. put them on and in 15K needing to replace again. It is being blamed on the control module and they say the part about 500. refuse to use the warranty because I didn't use their brakes.

The dealer sent in the information to the so-called warranty department. They made me send a receipt of the pads that were placed on the car. Then said they are denying the repair. I am like you this is ridiculous. Do you have a link to the information about laws against voiding the warranty? I don't give up easily. especially when it comes to my money.

Absolutely. Here is a link to the Magnuson Moss warranty act for vehicles


Shove that in their face. They CANNOT require you to use OEM parts and you can sue them for breach of warranty.

That dealer is a total A-hole and warranty company sounds like those scam 3rd party companies that they trick people into buying but aren't worth the paper they are printed on. File a BBB complaint against the warranty company as well as dealer and report them to the DOCA and state AGO where you are.
 
Oh boy!! All I want to do is have better rotors because it's my wife's car that I occasionally drive. She drives like the grandma that she is (in a nice way). The OEM on the CX-9 vibrates soooo badly and started doing that at 35K miles so I'm reluctant to replace with Mazda OEM rotors. Hollandog above said that Centric is good; agree?
Thanks for the input!!
have your control module checked? the same thing is happening to my brakes. they should never wear out that fast. mine is also vibrating terribly.

that is what i put on my car. Dealer is saying it is the reason for the e brake module failure and is refusing to replace.
Talk with the service manager, not just one of the service writers. Get the reason why the choice of brake pad will make a difference to the failed part. It can't be just, "They're not OEM." There has to be a reason. As long as the parts are suitable for the car, and what you put on certainly should be suitable, it should not affect the warranty. Wear items are, of course, not covered. That's pads and rotors. The brake module is not a wear item.

What warranty company? Are you relying on a so-called extended warranty? These are legally not a warranty. They are a prepaid repair contract, and both you and the company are bound by what is written in the contract. Read all the fine print. If you're beyond the real warranty and relying on the service contract, you gott'a do what that fine print says. If it says to use only Mazda brand parts, then that's that. Magnusson-Moss does not apply to these repair contracts. If you read it and still think you're covered, contact the company, not the dealership.

I don't think dealership is the bad guy in this case. Warranty long past so no obligation to help or good will. The rejection is from the warranty company.

I contacted PowerStop and got the reply below; I can wait like he suggests

Hi Richard!

Thank you for your interest in PowerStop products!

We do offer a kit for your 2018 CX-9, P/N# K7609. This includes our carbon-ceramic low dust Z23 brake pads, and our zinc-plated drilled and slotted rotors. (Front and rear) No modification is necessary to your stock system for installation, everything is included, and this should provide a nice increase in braking performance for you, while keeping your wheels cleaner. Be sure to break the pads in properly after installation for best performance!

That said, we are currently out of stock on the rotors, fresh inventory should arrive January 29. Some stocking distributors may have inventory, but you may have difficulty sourcing the kit until then (or a couple of days afterwards).

Amazon is fine, but it's usually better to search Amazon by "PowerStop K7609" rather than trying to find it by application. Amazon's automotive parts lookup can be goofy sometimes.

Let me know if I can offer any further assistance!



Thank you,

Eric Schneider

I found slotted only rotors. Check out r1 concepts. I'm not affiliated with them in any way. I just want to share the limited options we have.

I ordered a pair as they have 30% off today only.

Per the Magnusson moss warranty act, nobody can force you to use OEM parts on any repair or maintenance, whether warranty, extended warranty or "service contract". Further, the act provides that if the part that is covered failed and it is being blamed on a non covered part as to the reason for failure of the covered part, then it must be proven. You cannot blame a failure of a covered part on nonsense. It has to be proven that part caused damage to a covered part, which in this case absolutely does not, in any manner shape or form and it utterly preposterous to even claim that it did. The dealer needs to advocate for the customer to the company covering the repair and if they don't then they are making things up to have coverage denied, in which case they are dishonest losers who deserve to be put in the spotlight subject to bad publicity.

Btw, powerstop products suck and have the worst warranty in the industry. Source: personal experience many times over.
