⋯ On the other page(s) of that paperwork, do you see any line item that looks like number of hours for labor? It's just an insignificant thing, but I'm always interested in what the automakers consider to be the appropriate amount of time for a tech to do a job.
I believe the invoice OP posted says “UNIT 3.5” labor hours for HLA replacement.
 
Can you tell if the engine is using any oil?

If I were you, I’d gather some stats (gas receipt with mileage interval) to show very poor MPG, and tell the service advisor about the lack of power concern with the comparison going the same uphill. I’d ask what they can do to check such problem, and may be kindly mentioning if they can do a compression test and even a leak-down test to find out the engine condition.

And I’d do this way before my CPO warranty expires, unless I only intend to keep my vehicle for a very short period of time. And if I had a car with so many “major” problems like yours within warranty (valve cover、timing chain cover、and oil pan leaks、HLA failing at 25K miles!), I’d consider to dump it once the warranty is gone even though I’ve always wanted to keep a car forever. Call me superstitious, if a car keeps having problems since new, chance are it’ll keep having problems endlessly.
I can check on if it's using oil. Yeah I don't like all these things. Lots of issues for being such low mileage. I don't know that I'd get my money back on it. Plus I did 2 major credit checks for getting this car and doubt I would qualify again so soon. It hit my credit hard

I did notice that, but didn't want to believe that Mazda would actually be paying a tech for only that many hours for this HLA replacement job. But perhaps 3.5 really is their number, which would go a long way to explaining why these automakers aren't able to hold onto the better techs.

You’re absolutely right. Discussed with a master tech at my Mazda dealer about several questionable warranty repairs on my 2016 CX-5 when I asked him to re-check rear disk caliber condition base on a TSB which was denied by the tech who performed all the work. He said they have major problem to recruit good techs, compounded by most young generations who are not interested in doing the mechanical work which makes their hands dirty.

Not just the Mazda, car manufactures only allow a set labor hours for specific job under warranty. Usually the tech has to work for longer hours than set labor hours for a specific job. 3.5 labor hours allowed seems to be correct for the HLA replacement job although a good tech with HLA replacement experience should be able to finish the job within 4 hours without any break.

You might do a 0-60 mph time test and see how much longer it takes than other similar cars and what is posted in car magazines for your year car. Takes the feel out of it with real comparable data within a second or so due to temp etc.

Way back in time, there were always a bunch of 'car' kids, some of who turned into mechanics (most of them very good ones). But yes, times have changed.

And is the main reason why the few top shelf techs quickly figure out they can do much better for themselves by going to work for an indy shop, or even starting one of their own. So the stealerships are fine with just kissing the talented ones good by, instead of paying them what they're worth.

I took another look the job specs, and there's a lot of parts coming off and on; including (but not limited to) valve cover, both cams and all associated components, timing chain (partial removal), electric VVT motor and actuator, HPFP, and vacuum pump.

So this seems to my DIY mind, to be quite a bit more than a 4 hour job, particularly for a tech with average skill, knowledge, and motivation. However I'll also add that I certainly could be wrong about that, and agree with you that a very good and fast tech who has done this job a number of times, might very well be able to turn it around in 4 hours. In any case, I'm very much hoping to never experience any of this first hand.

I wonder if the new part number 0000-99-SCX5 for pre-assembled cylinder head set kit described in the Service Alert SA-058/20 eventually will be used for replacing 16 HLAs in addition to fallen rocker arms. If the SOP to fix fallen rocker arms by Mazda North American Operations is to replace the whole engine, they might as well just to replace the cylinder head with a pre-assembled one. And the labor involved replacing 16 HLAs is similar to replacing fallen rocker arms. The SA does mention the labor time needs to be reduced for cylinder head replacement job with this new cylinder head assembly.

Service Alert No.: SA-058/20 - NEW CYLINDER HEAD ASSEMBLY ESTABLISHED

NOTE: DO NOT USE the cylinder head replacement labor time listed in Warranty Wizard. That labor time is for a bare head and includes time to swap parts from the original head to the new head. Searching Key Words: Cam Journal, Valve Guide, Intake Valve, Exhaust Valve, Valve Spring, Hydraulic Lifter, Coolant leak, Coolant smell, Warp head, Engine Oil Leak, Oil Smell, Oil leak, Misfire, Low Compression, Excessive Leak Down, Burnt Valves, Rocker Arm
 
OP can always trade in to a 2017 CX5, the car is very similar to a 2018 minues the engine change.....the lower price due to age being a year older may help offset the trade-in cost. With some luck it might be a keys swap or a slight cost to the OP.

That's certainly a possibility in what appears to be some overall strategy and plan by Mazda Corp for this collection of CD-related issues. Time will tell about that I guess.

After finding out about this cylinder head alert last year, I took a print of it to my local Mazda parts dept in September, when I went in to buy an oil filter. The guy behind the counter was wearing a 'parts manager' badge or patch, so I figured he would be very much up to speed on what was going on with it.

But when I handed the paper to him and asked for his take on it, he said that he had never seen it before, and didn't know anything about the program! No idea how these things get communicated, but I would have thought he would have at least been aware of it, a month after being issued. Turns out I was obviously way too optimistic about that.

Maybe it's best to just put on the rose colored glasses and assume they've never had any CD-related engine problems, and don't feel the need to pay attention to any alerts related to that subject :rolleyes:

So just for a little explanation. The first one was done by a standard tech. When it came back in for the timing deal the 2nd time, they put the shop foreman on it. The noises I first heard (they wrote tickling but I actually said it was more like a loose exhaust shield sound-wise), are no longer there after seal and hla's. So that's good. My idle is much smoother as far as feel in the wheel. It just overall sounds better. They had told me that they cleaned up all the oil that had sprayed under the hood.I hadn't checked until today (got it back last week) how the engine compartment looked. I am absolutely blown away by how well they cleaned up under there! You can't even tell anything happened! I think there's no way to get it that clean other than while you're disassembling the parts for the hla and timing seal, you soak them in a degreaser and brush them. i mean all the surfaces looked new. I'm so impressed by that tech and the facility in general! The advisor thanked me for being so kind to which I responded that I was upset to bring it back but you catch more bees with honey than vinegar and that mistakes happen. Still debating if I should call about this power issue. Everything else is running and sounding great!

I always feel if a dealer is willing to spend time and effort to the vehicle repair, they’re the best with all the technical resources and genuine parts. In your case, if lack of power behavior (down-shifting when going up the hill), and poor gas mileage (25 mpg on the highway) are still there, you should find time to visit the dealer again trying to fix the problem before the warranty expires.

And make sure to check the oil level often to verify if there’s oil consumption issue.

I am surprised that they changed all 16 lifters and not just the 8 CD lifters, like they did for the other poster.

"The car says my mpg is 29 but my actual seems more like 25." You need to determine your actual mpg without guessing, and if it is only 25 on the highway then your car has a definitive problem you can have them address. Highway driving at 65mpg you should get 32-34 mpg. 29 is probably reasonable. It may well be a program update is needed to change the shift points.

The way my 2018 Sport behaves on a steep hill is, it doesn't want to downshift. But I drive it in such a way that I encourage it not to downshift by giving it less gas. If someone zooms up behind me and tailgates then I do have to give it gas and it will down shift.

Going down the hill, the clutch is locked and the motor slows the car. It will build up speed and I need to brake but it doesn't coast like it is free wheeling in neutral.
