Auto Start/Stop

I have 2019 RDX A-Spec. One annoying feature is the engine auto start stop. The auto stop should be on a delay i.e. when I park in my driveway , before I get a chance to put vehicle in park the engine shuts off . Then when I put the vehicle in park the engine starts up again! Then I shut off the engine manually. Also it seems the default should be auto start/stop disabled and turn it on with the pushbutton when you want to use it. As it now if you disable start/stop the next time you start the engine the sart stop is engaged again.

No need to select park, just hit stop after the engine shuts off. If will automatically go into park without restarting.

They make it on by default and force you to do it every time is due to EPA mileage ratings. If it is off by default or stays off when set then EPA does not let it be used in calculations for MPG.

If you donít depress the brake hard, it wonít turn off, you just have to be gentle with stopping.

Iíve noticed the same thing. When parking, you have to kind of lightly press the brake more to the side rather than the middle and it will not shut the engine off before putting it into park.

On another note, has anyone noticed that it doesnít work at all if you have any form of air conditioning on?

My AC seems to be on t all times—same as my 2016. But the auto stop feature works regularly on my car.

I, too, wish idle stop would wait at least a few seconds before shutting the engine off like other vehicles I've driven with auto idle stop. I realize the starter, starter relay, and battery are all beefed up and designed to withstand the extra tens of thousands of restarts, but shutting off the engine instantly the moment the vehicle stops moving only to restart a second or two later seems wasteful. You may save an incredibly small amount of fuel during a stop, but every restart uses energy from the battery and the alternator has to replenish that energy which uses more fuel.

My idle stop activates with the A/C on. The vehicle has what is called a "cold storage evaporator" with more thermal mass than a conventional evaporator. This allows the HVAC to continue conditioning the air for several seconds during an idle stop.

If it's too hot or cold outside or if the vehicle's interior is too far away from the desired temperature or if it's too humid, idle stop will not activate.

There are many conditions that will prevent idle stop from stopping the engine. There are many more conditions that will restart a stopped engine. All of these conditions are listed in the Owner's Manual - there are dozens of them.

Stupid system...totally unnecessary....might save a thimble of fuel each time but compared to replacing a starter or battery there's no cost savings.....oops I forgot, it's not about saving the owner money it's all about MPG. Wonder what the actual fuel savings is over, say 15,000 miles per year??? (probably less than 5-10 gallons/yr..........NUTS!!!!!

It is very easy to turn off and takes no time at all.

Another Einstein with no idea how much fuel idling wastes. The parts are designed for Start/Stop.

Like I said before, when I test drove the car this feature did not bother me one iota. It was perfectly fine taking off from a dead stop at a light.

I mean, where do I think I am, on a big round NASCAR track or trying to show up the guy next to me like Iím in a Lambo or something?? No.

It was perceptible, but hardly something Iím going to get my knickers all knotted up over. Itís there for a purpose and Iím OK with it and it took nothing away from my driving experience in the least bit.

AND... You can turn it off, like as been said many times, if this thing is so traumatizing and sleep-depriving.

Shame on all who don't utilize start/stop. Your killing the planet, burning fossil fuel needlessly... Did I mention I disable mine with every drive cycle.

My car's is pretty obnoxious and I turn it off sometimes if it becomes problematic in heavy traffic (it usually doesn't) but I think it's just important that we point out that engineers have come up with solutions to allow us to enjoy bigger, more powerful engines.

I think it’s a smart system. Easy to turn off if you dislike it. I’ve observed the mpg difference when stopped without it and when it is engaged. I like helping the environment and I don’t object to better mpg.

Duddnít bother me one bit either. I turn it off when conditions require it, but they do that less than a quarter of the time. Whatever it saves, it saves.

THANK YOU!!!!

Just picked up my RDX Saturday and when i was parking it last night in the garage, I thought to myself "why do i have to push 3 buttons (P Brake, Park (tranny) & engine off)"...

I've found that if I use the right side of the brake pedal and don't press it very hard, the system won't activate. That eliminates turning it off before putting the car in Park. And when I'm at a light, if I press the brake pedal in the center and press it a bit harder as the car stops, the system activates.

Actually the engine will wear out faster by not having oil on the top of the engine every time you start, tested by many mechanics, fault will only happen after the warranty wears out, of course.

Hmmm. That'd odd. I wonder how the gasoline engines in Priuses and other hybrids make it hundreds of thousands of miles then. Their gasoline engines are stopping and starting a lot more often than our RDX's. There's no electric oil pump that runs when the engine shuts off to keep the top of the engine lubricated.

Can't compare with deep cycle 500v Prius expensive battery with a huge generator instead of a tiny starter, Prius was built for that.

Video from a mechanic for 50 years.
I'm not saying not to buy it, just not worth the saving on gas. My next car maybe all electric, like the RIVIAN truck, great specs and torque.

In reference to your comment below, batteries and starters have absolutely nothing to do with engine lubrication.

That "50-year mechanic" is a tool. He hates everything except Toyota and only occasionally and accidentally has sound advice. He'll say anything to make a buck from a YouTube video and sort of reminds me of an automotive Howard Stern.

Just look at that hoarder's garage. I wouldn't let him near any of my vehicles!

If he has been a mechanic for 50 years, he is most likely stuck in the past, and unwilling to accept new technology. I just can't take advice from someone who constantly shouts negativity and waves his arms at me. Honestly, he sounds like a carnival barker!
(I deleted the video from the quote above as I don't want to promote this annoying guy.)

I honestly don't see the issue folks have about this system. If you don't like it, just push the button when you start the car, or the first time it engages.. How hard was it to learn to put your seat belt on, or to turn on the turn signal when turning (oh, I better not get started on that!) or to turn up or down the volume on the radio, or select reverse or drive, etc? It's one button, in easy reach.

Come down a freeway off ramp with the brakes smartly applied, see the traffic to your left is coming, but not there yet, hit the gas to quickly go (for a right turn) and notice the engine has turned off. Now you are in the middle of an intersection with traffic to your left fastly approaching. Not safe according to my wife and I totally agree. I would disable it by default in a heartbeat and turn it on only at a long light. I absolutely hate it when it turns off and then immediately back on, now that is a waste of starter and battery. For the record, I usually push the disable button, but will forget at least once a trip until the engine turns off, then I make sure it is off.

The mechanic might have been working on cars for 50 years, but what did he say that was wrong?

That although Acura states they upgraded the starter and the top engine parts, he doesn’t trust the wear and tear of all those additional starts? He doesn’t trust it, that is not provably wrong, is it? How much actual gas can you save? Three cents a drive?

There is lots I don’t like about the start stop, and while it is OK when sitting at a traffic light, there are lots more situations where I don’t like it. Stopped at a green light waiting for traffic to break before making a left? I want that car to go NOW. Entering traffic from driveway or parking lot? Same thing. Stopped at home opening the garage, STOP, pulling in, STOP, put the car in Park, start-stop? Who needs that?

Yeah, I know I can find work arounds, like not pressing fully on the brakes, or turning the engine off while in drive. But who needs to remember all that, when I can just remember to turn that thing off?

If I know I'll be going again soon, I'll lightly press the brakes to not trigger idle stop. But if idle activates, I just immediately slightly untap the brakes enough to reengage the engine.

Or, if you've left enough room, you can creep up a few feet, and the auto stop will not re-engage.

Or you can turn the steering wheel slightly. That starts mine up and does not re-engage the auto start/stop until the next stop.

Start/Stop is definitely dangerous when you're trying to quickly get moving for whatever reason and you forgot to push that button when you got in the car. A safe car is a predictable car. This and all the various nanny features (auto-brake, auto-steer, auto-whatever) should be programmable in the settings to be permanently set on or off as per the driver's wishes. It could be also based on individual driver's preferences tied to the key fobs. A driver should not have to do all of these customizations every time they get in the car.

Agreed, but it won't happen with start/stop, because they will not be able to claim it in the MPG calc. Or so I'm told.
