WOW!!!!So Mazda's not the only one to have problems with oil pressure controlled HLAs. Here's an interesting article about Hemis nine years later. Many differences, and nothing definitive, but the similarities are striking. Time will tell.
Just by way of information, I have the turbo version of the 2.5L, which does not have cylinder deactivation. That engine is in the Reserve and the Signature trims. So my experience is strictly second-hand from what I read here and elsewhere.
But all's been quite since the updates. And as you said, you have 5 years of coverage on Mazda's dime.
No. All's been quiet with the CD engines since the updates.Wait, am I understanding right? There's an ECU update for the Turbo version too?
Call your dealer.I'm wondering if my local dealers have the PCM programmers on hand or have to get them from Mazda. I haven't had this recall performed since I rather wait at the dealer instead of having the dealer's staff picking up my car. This C-19 crap is a PITA as far as getting service. My car has just shy of 6k miles, and due to the highway driving I do to run the car after being shutin the house all week, it's giving me the best average mileage (close to 34 mpg) ever! I'm probably not taking my car back to the selling dealer since we have had bad warranty experiences from them for our other Mazda.
Software fix... from my reading here, it sounds like the pressure must be above a certain level to prevent the mechanical failure for cylinder deactivation. I know that parts wear, clearances widen and pressure drops with wear and tear on an engine. As the engine ages and clearances widen, whats to prevent the pressure from dropping on higher mileage engines. I intend to keep my Mazda at least 200k miles.... can anyone with an in-depth knowledge of the actual software fix respond? Mazda? Mazda?
Reach out to Mazda directly by writing to them...not here on forums as they likely don’t read owner forums. You can relay your concerns through the dealer and that’ll ensure the message is passed on. If you go thru the proper channels you’re likely to get a better, more accurate and technical response than from forums
Your concern is exactly what I have, in addition to the bad reputation historically by cylinder deactivation. That’s why I personally gave up the plan of getting a 2018 CX-5 once I found Mazda suddenly added the cylinder deactivation feature for 2018 MY.Software fix... from my reading here, it sounds like the pressure must be above a certain level to prevent the mechanical failure for cylinder deactivation.

The best you can get for this cylinder deactivation problem is the description in the related Service Alerts and TSBs posted earlier in this thread. Good luck to get more specific details about this issue from Mazda North American Operations, not to mention from any Mazda dealerships.Reach out to Mazda directly by writing to them...not here on forums as they likely don’t read owner forums.

So you’re saying a new member went through this long thread with 752 posts, but can’t post a question about the issue, and we can’t answer or comment the question he has?Gentlemen,
Please stop poking up this issue.
Subject has ben dealt with by Mazda.... since many months no issues anymore.

If you re-read the original post by OP Go Hawks, he couldn’t get any info about the problem after 7 months of repeated tries. Hence came over here created the thread more than a year ago hopefully someone else wouldn’t encounter similar dangerous situation he and his wife had experienced.His question is not one that we can answer, thus the recommendation to contact Mazda directly. As mentioned, they would have access to more information than we do. The problem is getting them to supply the information. Either way, you can't get the info without asking for it from the proper source.
Your experience is your experience, and it is of course worth taking into account. But other's experiences may vary.

Yes you can suggest TotalMazda1 trying to get more details about the issue, but IMO he won’t get anything more than things we had discussed here, may be even less.
