And the Service Alert by Mazda doesn't explain the reason why the rocker arm fallen off, but told the CX-5 owners who have had this problem that the updates on PCM software should fix the problem. If this problem is this easy to fix, why Mazda hasn't been updating every PCM with cylinder deactivation which has already sold on the market? And why a new engine is required to resolve this problem?

    To me, this's not a reliability issue, but a safety issue like the OP said in his thread:

    Dangerous cylinder deactivation trouble on 2018 CX-5 and 6 models

    And getting an extended warranty won't help you to resolve this potential problem at some point.
    Car companies need to see the issue show up in a certain percentage of their cars before offering a recall like you describe. Even though a software fix is effectively *free,* Mazda will lose a ton of money when 150k customers descend upon dealers and suck up labor. That*s why Mazda, like any other car company, addresses these things incrementally.

    And I call BS on characterizing this as a safety issue. Yeah it sucks if your car stalls, but that can happen from something as dumb as driving your car on empty or overheating your clutch (in a manual). As far as I*m aware, there aren*t any safety campaigns out there demanding that people keep their car fueled. Real safety issues are loss of brakes, fires, explosive airbags, etc. I know you*re waging jihad against CD, but it*s over the top to call it dangerous.

    How many times we've seen a safety recall forced by NHTSA described as a sudden loss of power? What does the title say created by the CX-5 owner who called the situation "dangerous"? His wife now is afraid of driving her CX-5 after the incident of sudden loss of power while passing on a two-way highway without any prior warnings. If there's enough CX-5 owners (26 cases until Oct, 2018) who experienced such issue and all filed the safety complaint to NHTSA, a safety recall will happen in the near future.

    Uncertain or potential sudden loss of power without any warnings is indeed dangerous to me. In this case it's different from the examples you listed as for those you will get some sort of warnings. It's your choice whether you want to take such risk or not. Just don't say you didn't get warned.

    The difference is the first examples you gave are of the driver being an idiot. If you're an idiot and the car stops working that is on you.

    The issue with the CD stalling is you are operating the car perfectly normal and then it stalls on you out of nowhere, trying to cross a busy road, at highway speeds, etc. Anytime there is a sudden unexpected loss of power not caused by something the driver did, it is a safety issue. There are hundreds of recalls to back that up.

    I mean...this is an unexpected loss of power that you are not in control of. Outside of what you are in control of, you are not in control of the cars around you when you unexpectedly lose power. To me this is absolutely a safety issue.

    This is the gray world of deciding if the impact of an issue creates a safety situation. I'm with jmhumr (above). There are many reasons a car can stall, go into limp mode or suddenly stop moving. Even if the reason is a defective part or defective programming that doesn't automatically make it a safety recall. This may become a recall issue someday - but I can see both sides of this argument. So far, based on what I know, the current response is appropriate and this is is not a safety issue.

    Well, despite all the stuff about rocker arms, picked up our new ‘19 touring awd w/package yesterday. Pretty nice vehicle and my lady is stoked, especially with the apple carplay (as am I...it’s pretty damn cool and convenient). Going to be putting 100k miles on this thing in the next three years, so guess we’ll see how it holds up.

    Fair enough, Service Alert, not TSB. In any event, I would have the necessary software updates done, referencing the two Service Alerts. Once that's done, I'd drive the car normally and give it the beans on an open road a few times to make sure it doesn't exhibit the symptoms of a rocker arm that has fallen off. If it doesn't, then I'm home free

    If you noticed, Mazda won't update your PCM firmware unless you have symptoms. This shows the rocker arm falling off problem is not as simple as PCM software updates. Saw today there's another TSB for 2018 CX-5 concerning P0524 CEL about low oil pressure which also requires PCM update. IMO this's also cylinder deactivation related. According to the TSB, what Mazda did on PCM update is to control engine oil pressure better in certain situations. This sounded very similar to the fix of rocker arm issue to me.

    What I'm saying is that IMO, Mazda should check the related software of the new vehicle to make sure that it has been updated. According to them, if the software is updated, the rocker arm will not fall off. This is in Mazda's best interest, because if they do not update the software and the rocker arm falls off, Mazda will have to eat the cost of replacing the engine (and updating the software anyway). If they refuse to check it, I would reference the Service Alert(s) and state to both the dealer and Mazda Corporate that you do not feel safe driving the vehicle due to the information presented in the Service Alert. As a last resort, I would threaten to bring this information to the local media.

    For something like this, I would not be so easily turned away at the gates.

    I have a 2018 with close to 20,000 miles that I bought last September with 2 miles on it. Absolutely no issues so far. I guess my only bitch would be that the oem wiper blades suck in the snow; and the "heated" area on the windshield doesn't do anything if you're driving in a snowstorm. Other than that, no issues and I drive it pretty hard.

    Is there any compatible aftermarket wipers for the Gen 2 yet? I know I put Bosch Icons on my Gen 1 for the same reason. Stock wipers are absolutely pathetic in wintry weather.

    Bosch Envision 24OE and 18OE. Has to be OE version to have a proper adapter.

    Now I really need to get used to $29 per wiper blade!

    First post but lurking for many months.
    I have to think that long term reliability with the turbo itself could overall be a larger issue and eventually affect more people than the rocker arm issue. Nice to have that extra grunt and it appears the only penalties are more frequent spark plug changes and lower fuel economy and maybe the cost for premium fuel for those wanting the extra hp premium gives. Turbo will also put more stress on transmission, maybe tires and brakes, maybe more underhood heat etc.
    I would have no hesitation to pick up a GT and this is number 1 on my list, actually replacing a 2004 Acura TSX with 250,000 km and similar power and driving dynamics. I like the idea of a conventional non turbo engine with a simple 6 speed trans...not 9 speed, not CVT.

    Like you I also hate to get a turbo engine for long-term consideration. Unlike you, if I have to choose one between 2.5T and 2.5L with cylinder deactivation, I'd choose the 2.5T! That's how much I hate the CD and I even gave up my plan to get a 2018 CX-5 GT AWD mainly because Mazda suddenly added the CD.

    Now we started to see some design issues on cylinder deactivation from 2.5L with CD. I'd predict there'll be more problems coming out as time goes by.

    Actually CVT is much simpler than a 6-speed transmission …
