2016~2023 CX-9 Common Repairs Thread

[Fruitwolf]

Here’s a chance to share your repair misery.
Any 2016+ CX-9 owners have a significant repair? This should’t include common TSB items (such as faulty infotainment screens) or the dreaded cylinder head crack.

- Water pump replaced 65k
- Brake booster replaced at 117k.

Just curious to see if there are certain common repairs to these vehicles. Thanks in advance.

2018 CX-9:
Rear diff replacement at about 110k kms (~68k mi)
Front passenger side LCA and both front struts replaced at around 120k kms (~74.5k mi) - this was due to hitting potholes with 285/35/22 tires while being lowered on CorkSport springs.
Upcoming thermostat and ECT replacement at about 139k kms (~86.3k mi)

2022 CX-9
Oil control valve (small leak) replaced at about 45k kms. I think this is a common issue on these motors?

Is that the one at the top of the engine (passenger side, near the firewall, under the engine cover)? I have a small leak there as well, very minor.

Yes.

They replaced the entire OCV and the plastic engine cover (didn't feel like cleaning it?).

Was never enough to see any changes (significant an otherwise) to the oil levels between change intervals, but just visual (I, like probably many others on the forums, actually look inside the engine bay every so often).

Navigation screen has internal cracking. May be a DIY given dealer quotes.

2018 cx 9 gt. Just replaced rear diff @ 157KM. $4800 cnd. Dealership advisor also quoted some crazy prices for brake jobs. $850 cnd for rear brakes. Picked up and installed Akebono ProActs for $112 cnd. Quoted fronts as well stating they were worn. Inspected myself and they are likely not even 50% worn. $750 cnd for fronts. These prices didn't include brake fluid flush. Also tell me both front control arms need replacement. $1750 cnd. I'll be getting a second opinion in the spring. It drives and rides nice with no squeaks so I'll get them looked at in spring.

Was the rear differential replacement just due to excessive wear? And was the oil ever changed, to your knowledge?
Asking because that seems like a premature failure.
