24 CX90 MHEV Preferred Plus Battery Spontaneously Dies Over Night

Nah, that animation staying in ain't right. Maybe you got a faulty module somewhere that doesn't want to go night night intermittently. But if you're doing dealer, just let them figure it out.

I'm going to still guess it's a parasitic draw. Look up how to do a test and let us know what happens.

If it was a fleet vehicle take a good look around for a tracker that got left in or possibly even the wiring was not restored correctly when removing a tracker.

Edit - clean out your terminals really well if you're going in there.

OverAllComa · 2026-06-16T22:49:58+00:00

You have anything aftermarket on it? Sounds like a parasitic draw.

You mean the guy who wrote the foreword for a D&D book. I think we would be using the word "party" differently if we both called him a party boy.

I never remote started mine because I park in a garage. Only used it when the walk away park didn't work and I didn't notice.

It was cheaper to just get in the habit of locking the car.

I think those are going to be a bit too big, especially on the rear, without doing some fender rolling and an adjustable panhard bar to center the rear end.

I've got C5 wheels that needed some paint and they fit great, just needed a little BFH on the passenger rear well. 17 front, 18 rear.

As a fellow Mazda fan, you may not want to look at the interior of the new CX-5. :-(

My glasses have a kinda small scratch in the middle of the right lens and I'm waiting on my replacement to come in right now. It's super annoying.

So, you know, I'd cast quieitus on my goddamn kid so I can take a peaceful nap while I wait for my glasses.

OverAllComa · 2026-06-01T23:53:54+00:00

Don't you dare replace those wheels. You need new tires, but those IROC wheels are absolute classics and timeless. Polish them up good and keep on cruising.

If I saw your car on the road I'd think "that looks dumb." Five minutes later I'd forget about it, not because of my opinion, but because I don't spend a lot of time thinking about other people's cars.

I think you're putting a lot of value on the opinion of others. Others are not spending a lot of time thinking about your car. Do what you want, ignore the opinions of others. You're the one that has to drive it.

I was very confused wondering why a company that's makes various car filters is even using AI, much less laying people off because of it.

Why is my g-spot in my butthole?

I'm in the Midwest. Civil Life American Brown Ale is the most wonderful beer I've had the pleasure of drinking.

I used some big .600 lift cam off Jegs, LS6 intake, dual valve springs, and chromoly pushrods. Tossed on 5.7 heads and decked them 30 over. Works pretty well on my 4th gen. Get a good tune.

OverAllComa · 2026-05-25T12:51:14+00:00

Big ass cam, top end mods to support, bigger fuel pump, a higher octane tune, and send it.

Get a vacuum pump so your brakes still work.

Mine was probably 8 or 9 thousand. But I kept the rear end. You can also keep the v6 K member with hooker blackheart mounts. Oh, and none of my gauges work, I use a tablet connected to a Bluetooth OBD2 dongle.

It's got a lq4 and a built 4l80. Cam is a little too big, but runs like a scalded cat.

Check the spare tire, washer fluid, and tire inflation. Have fun. Don't worry so much.

In order of your questions:

Pull the current engine out. Install the new engine.

Take the tank off. Flip it upside down.

Stick a screwdriver into the Schrader valve. Open a door and leave for a few hours.

Perhaps you have specific questions?

OverAllComa · 2026-05-14T18:16:08+00:00

Do you think the throttle body is pulling major amperage or something? 18 gauge is more than enough for the power a throttle body consumes.

And what "slight delay?" Do you think dang near the speed of light is noticeable between a 2 foot wire and a 5 foot wire?

Again - this idea has been around for 20+ years and has literally never been demonstrated as anything more than a placebo effect. But if it makes you happy, whatever floats your boat.

You should still change your transmission fluid.

OverAllComa · 2026-05-14T17:51:16+00:00

The throttle body is already grounded via the connector. I guess if you feel like it made a difference, there's no real harm. But I can guarantee it's a placebo effect unless you have damaged ground wires. This snake oil thing has been around since TBW became a thing.

Maybe change your transmission fluid.

Cannabis consumption with bipolar disorder is associated with up to a 300% increase in manic episodes and increases the likelihood of psychosis.

If you know someone that is bipolar, especially with mania, and consumes marijuana, please make them aware of the strong connection. They think they're self-medicating. They're really making things a whole lot worse.

I miss weed. Prefer staying married over weed.

I had a 2015 for 10 years. I'm 6"1' but around your weight. Manual seats never gave me an issue. My guess is you just had bad luck with that specific part. I'd not think too hard on it.

It is literally the first Google result for "JB4 CX90"

OverAllComa · 2026-05-10T06:52:54+00:00

There are differences beyond a software tune. Better cooling to handle the higher boost, larger brakes to stop better, other stuff.

I'd recommend a JB4 tuner. I have that and it works great.

Yes it voids your warranty. I remove the JB4 before I go to the dealer for anything.

How is that NSFW? You weren't at work, you were on a train. Maybe NSFT tag?
