I got my wife one and there have been minor recalls but dealership is great at sending us video updates on all the work and suprising Lu I’ve never had it sit more than 2 hours at dealership …..once was for some brake thingy update and another was for an update as well. Both really simple on and outs. Other than that lord she drives like a champ!
Great job as a Mazda Tech!! You showed a conscientious attitude and completed the work professionally. I wonder if tech's like you are elsewhere doing this in the same manner??
@shopforemangarage Very interested in the inline 6 cx90. May sound like a weird question but maybe you can put my mind at rest. I noticed how far the engine sits under the windshield area. When it comes time for me to have a mechanic change the spark plugs can it be done without removing or lowering the engine? I'm concerned about the cost of this routine maintenance requirement before I buy one. Thanks for your insight
I'm not sure. I have not removed plugs from one yet. I figure it can't be more than replacing plugs on a V6 that has a plenum that must be removed to get to one bank of plugs.
There is nothing wrong with this vehicle. This model and the PHEV are solid vehicles. The inline 6 cylinder turbo is what Mazda calls the mild hybrid. If you like Mazda, they are nice. Then there is the up and coming Mazda CX-70 with the same options. Just so you know. I'm not a salesman. If you're in the market for a new vehicle. Buy whatever inspires you.
This doesn't seem that hard. I wonder why it took my dealer 4 hours to complete it... Curious to see more Mazda CX-90 TSBs if you have the opportunity. In particular, the one with front and rear suspension grease to stop it from creaking and popping
That TSB for the creaking and popping could take up to 4 hours depending on how bad it is and when you include the alignment. I have not had the opportunity to perform that TSB yet. Unfortunately, my Mazda content is dependent on what walks in the front door of World Car Auto Group. If I get the opportunity, I shure as heck will make a video. Thank you for your comment and the suggestion.
Got the recall work done 3 weeks ago. The steering was much improved, but not completely rid of...the "steering effort." But, a trip to another city revealed again...the same problem. It is most noticable on the 1-30 expressway loop in Austin, Texas. Going 90 mph, you do NOT want any weird and not-so-wonderful jinks in the steering, and I noticed it FOUR TIMES as I changed lanes. What to do, then? Take it back to the shop every MONTH or what? For a re-GREASER jobby, sirs? All I can think of...this is a TEMPORARY "fix" at best, which is the condition of this BRAND NEW vehicle.
Mazda does. They said that the worm gear friction force may be excessive which results in increased force required to turn the steering wheel. So if that new spring in the worm gear applies less friction force then I believe it is the long-term fix.
From the very first time I touched a CX-90, my first thoughts were BMW and Mercedes. There are some systems on this vehicle that I would hate to have to work on.
Great explanation as to what is causing and being done in regards to the increased steering effort plaguing the CX90. What caused the grease to seep from behind that plastic piece in the first place, and what’s to prevent it from happening again? By pushing the grease back behind the plastic with nothing done to seal that gap almost guarantees that it going to happen again, no?
My thoughts exactly. Mazda never mentioned it. I believe that the grease was never pushed into place properly when it was assembled. They said that the worm gear friction force may be excessive which results in increased force required to turn the steering wheel. "Dealers will redistribute the grease to the gear teeth and replace a spring with an improved part that reduces the spring force to the worm gear." I believe that it is the new spring between the inner and outer caps that actually fixes the issue.
CX-90 PHEV Electrical leakage, what's the fix for that? PCM POAA6:00 Failure Type No Additional Fail Type Informationa DTC No Additional Fail Type Information DTC PCM PODE6:00 MS01-186B14 MS05-186K2-S Description Hybrid/EV Battery Pack "A" Voltage System Isolation Fault Hybrid/EV Battery Pack Cell a Voltage Low
I have not seen or heard anything about electrical leakage. What I do know is that the CX-90 uses a high voltage A/C compressor and Mazda says that you have to use their POE refrigerant oil. "Using any POE Oil other than Mazda Genuine POE oil may cause electric leakage , deteriorated A/C performance, or damages to A/C components."
I wanted to purchase this Vehicle very badly, but doing further research has scared me off. Primarily the highly complex nature of it. The timing chain in the rear requires an Engine pull ? No thanks
Oh yeah. I would not purchase this vehicle to work on. The first time I saw that I thought to myself, BMW, Volkswagen, Mercedes. There are a lot of things on this vehicle that are hard to get to. Things that are easier on other vehicles. You can't even disconnect the battery without taking out the cowl panel. Front diff. is bolted to the engine and oil pan. Passenger front axle goes through the oil pan.
Timing chains don't normally wear out. Unless on a very high mileage engine the chain can stretch and get too much slack in it. Usually if the timing chain goes out, something in the engine caused it. Timing chain would be covered under powertrain warranty.
Mine is running great. Other than a couple of minor recalls, no issues. Puts a smile on my face every time I slide behind the wheel.

Good to know she's doing good for you. Thanks for the feedback.
Excellent work Maestro! Do you think the timing cover leaks on the 2.5 cx-90?
I have not seen that yet.

I hope so. Thanks for the comment and your support.
Gorgeous car regardless
We agree!

I thought it says in the TSB Recall to keep the vehicle in the air and steer back and forth to see if it feels notchy?
Your right. It does say to check if the steering is binding or feel heavy.
I was strongly considering this car, I am scared now. I was hoping the PHEV would be a good option. 😩😩😩😩

Mazda has been the hidden treasure for the last decade. This vehicle out BMW the European cars.

Take it back. The grease is not what fixes it. Its the tension on the new spring. Maybe they put the wrong spring back into the steering gear.
Great content! But do you feel this is really a long-term fix?
Mazda does. They said that the worm gear friction force may be excessive which results in increased force required to turn the steering wheel. So if that new spring in the worm gear applies less friction force then I believe it is the long-term fix.
basically 15mins of a guy lubricating and caressing an engine part with his finger
That engine sounds pretty complicated.
You're right. Mazda seems to like to complicate everything.
The cx9 and cx5 must have been too reliable, so it seems they hired german engineers fornthe cx90 lol

I used MDARS to clear codes so the car can be driven otherwise it was unable to switch out of park. All modules are up to date at the moment.
Yes, MDARS is needed to scan a CX-90. The IDS is an old Ford based scan system and won't work with new Mazdas.

I guess timing chain replacement is a normal wear item and not covered by any warranty.
