According to the 2022 Owners Manual, Idle Stop is disabled when you are in Snow Mode or Sport Mode.

Gonna have to try that first thing tomorrow.

 

I don’t think that has changed the past three years

 

Unfortunately it reverts back to Normal mode the next time you start the car. Just have to get used to pushing the Idle Stop button.

 

or put on the idle stopper device, or build one.

 

True but I’d rather not tear the dash apart in a new car.

 

Thanks, never noticed that on my '19, but then again I used comfort mode almost exclusively.

 

Hit the defrost button, turn of the a/c and adjust fan to low setting. It disables stop/start. You don't have to reset it each time.

 

OR...

OPEN HOOD, START ENGINE, CLOSE HOOD
Why doe this work? Because one of many conditions where the Auto Idle Stop will not work:The engine is started with the hood open.

So To enable AIS again:
Turn off the engine. Close the hood before you restart the engine to activate
Auto Idle Stop.

Auto idle stop POST#55

 

How long does this stay in effect? I believe I tried this one some time back but it didn't last very long

 

To each their own, but for me, I think this thing is overhyped. I just got used to moving my foot from the brake to the gas pedals slowly, in that case, the engine starts very smoothly and it's not intrusive. I have this on both my cars, hated it at first but don't even notice it now.

 

Doesn't bother me at all.

 

I got used to it and it is not a problem for me.

 

Don't you worry, it'll develop rattles soon regardless.

I simply got used to hitting the Stop/Start button as part of my start-up procedure while I wait for the infotainment to load. Start car, buckle seat belt, turn off Auto Stop/Start, turn off CMBS, check mirrors and usually by then the infotainment is just about loaded.

 

I’m sure the 2022 rattles are all ironed out…..


The infotainment is definitely faster though.

 

I absolutely love it, Your car is quiet and still as a churchmouse at traffic lights and when stopped in traffic. What's not to love? I get PO'd when it DOESN'T kick in.

 

What’s not to love? Left turns with oncoming traffic. When that happens, I lift off slightly to start the engine.

 

OK. problem solved. But, it's still great in the situations that I described.

 

I personally wouldn’t go so far as to say it is great. But it is easy to get used to, easy to adjust to conditions, and it is the way cars are nowadays. I don’t think it is as severe a problem as some other folks think.

 

I never had rattles in my 2019, and based on past experience I am very confident I will not have any in my 2022. Also for those that were saying that the infotainment will be fixed with software updates I am LOL 100 times. I always said it was the hardware, guess what, no more issues in the 2022 @russianDude

 

In the 2020, AIS is disabled in Snow or Sport+ mode, but both of those revert to Comfort or Sport when the car is turned off. I don't even notice AIS anymore...especially if music is playing. I do wish it had a slight delay as it can be slightly annoying at Stop signs.

 

In my new 2022, i constantly get the message that the AIS is disabled temporarily because system is charging or warming up. This happens even if the car has been running for a while and is fully warmed up. AIS initially worked fine for me but now it never enables itself. Occasionally instead of that message, i get the one that I need to turn the AC off to enable it. I too used to always turn it off in my 2019 which I traded in for the new one and glad that I don't have to turn it off anymore but its annoying to see those messages plus the fact that its probably broken or something is wrong. I have not bothered going to the dealer about this yet.

 

My 2021 Aspec SHawd gives me that screen that is not available 90% of the time lately. Might be due to the extreme cold weather in the winter and not perfect conditions for the RDX. Even on a round trip 30 mile drive, it hates to go into AIS with temps below 20. Doesn't appear to save much on MPG, as the RDX is thirsty in cold, hot and windy conditions - heaven forbid you pound on the "go pedal" and the turbo spools up - she drinks petrol like a drunken sailor on a night out @4/gal. for premium.

Personally, I hate the AIS feature - I turn it off most of the time, just wish the light on the dash was a dark blue (similar color to the high beams dash indicator), rather than the bight orange that is annoying when driving at night.

 

I'll try and pay attention to see what happens when the weather warms up, it could very well be due to cold, its been a while here in Chicago since we've had above 25 degrees temps

 

The biggest annoyance is at stop signs. It's off for less than a second.

 

Temp recently got into the 50's and no change with the idle stop, it simply does not work anymore no matter what I change with the climate system or otherwise.

 

I had a similar issue where to stopped working and kept telling me it was unavailable. However, went to wash the car the other day, popped the hood when the car was running to wipe it down and then shut it - right after that is started working again. Know it says in the manual that turns it off when you open the hood when running and I read in this thread to open it up again and shut it corrects the issue. Kind of a dumb setting, similar to the antics you have to do putting into "car wash mode" when you need it to stay in natural and just go into park when you open the door.

 

I agree on not tearing the dash apart. The auto start-stop button is a whopping 4" from both the engine start button and the reverse or drive button.
I'm not getting why it's such a big deal to use some self discipline to turn off the feature before you drive. No different than buckling your seatbelt.

 

Everything is a big deal in this forum. Between this, the “minimal” screen and the seatbelt chime I’m not sure how people survive when they have a real issue.

 

My start/stop hasn't worked since a dealer visit in July of last year on my '19 RDX... 2 months after I got the car lmao. First dealer said everything was fine when I brought it up to them, that they ran a diagnostic and the system was working as intended. But I know this isn't the case, because it hasn't worked since I got it back from them after getting the intercooler replaced (limp mode issues). I know there are several variables and conditions that have to be met for it to kick in, and I've made sure it's not an error on my end. I've also driven loaners under the same conditions as mine, and the feature works as expected.

I brought it in for service at the dealer closest to my house today, and I forgot to bring this up to them because I was more concerned about the squealing brakes, which they seemed to have fixed! I've tried the different methods listed online of re-enabling the function via opening and closing the hood, but I just cannot seem to get it working again. When I enable the start/stop display in the meter, the only message I ever see is that the system is unavailable.

I'm not sure if I'm doing the process right, can someone please chime in?

Taking this process for example:
Follow this: I'd pop open my hood, start the engine, and then close the hood. With the hood closed, I'd then turn off the engine, open the hood, and close it again (which felt redundant), then restart the engine and it should work.

I've also tried this cutting out the redundant part: Pop open my hood, start the engine, turn off the engine, close the hood, then restart the engine and it should work.

Since neither of these have worked for me, is it possible I'm doing something in the process wrong?

 

I had this same exact problem. My Idle/start stop quit working no matter what, and the dealer then traced it to a sun sensor problem that kept the auto/idle stop from functioning. Once they replaced the part and replaced the battery, the issue fixed.

 

This is actually really good to know! I’m screenshotting this to show my service advisor 😊

Thank you for that!

 

It's not disabled in sport mode on my '21. If it is in the '22, that would be an improvement...maybe. I disliked it at first. Then when I got into the habit of disabling it, I noticed the gas mileage unwinding when I stopped. Decided maybe it was worth putting up with.

The one thing I don't like about it, in spite of what someone said above, is it's about the most in-elegant restart I've seen in a vehicle. It's pretty rough. For a "luxury vehicle", you'd think they could somehow have done better. With only 4 cylinders to turn over, maybe not.

The trick to avoid the momentary shutdown at stop signs is to not stop - just slow down to 1/2mph or so - if it's safe to proceed.
