Start-Stop Technology

We have been waiting for the 2020's to arrive to purchase a CR-V for my wife. I was hoping for better looking wheels, perhaps more progress on the oil dilution issue, and other mid-cycle updates. I now found out that the 20's have Start-Stop technology, which I very much dislike. I drive a Rav4 Hybrid, which I love. It is not the same, since it uses a large electric motor to start, and is much more seamless, with proven long term reliability. Because of this, We are now thinking of picking up a left over 2019. I under stand the start-stop can be shut off, but you have to do it every time you start the vehicle. Fuel savings for this are negligible, and would certainly be negated by a starter replacement. I was wondering if anyone who has experience with a vehicle with this technology had any thoughts or comments. I have talked to several people who have had rental cars with it, and they all disliked it.

It's a special start-stop starter motor, no need to worry about premature wear. It's not as much the fuel economy issue (there is some effect in start-stop traffic), it's cleaner air.

I have two diesel cars with start stop. Works great, there's nothing to dislike really. You'll lose 0.2 seconds at traffic lights if this is a factor.

Perhaps, but if fuel economy is hardly impacted, how much effect is there on air quality. I guess every little bit helps. As far as premature wear, I would think you still have the issue of exponentially more starts without oil pressure.

Our new Honda Passports have this (... we had full awareness of this prior to purchases...) and it is very annoying rumble/vibration. If you are in traffic where each car moves just a few meters the system constantly alternates stop-go-start and it cycles with AC on/off. The noise is very loud also when starter engages.

So, we just always remember to disable it at 1st start. Have to press a button on shift panel anyway so do it at the same time as pressing D/S.

My 17 crv doesn’t have it
But my wifes work 18’ equinox does.

it was slightly annoying at first but im used to it now, (although if it was an option i wouldnt select it)

i just lightly lift the brake at lights to trick it to start so that it doesnt have to engage when i need to move.
We dont really care about the mpg since work pays for gas/car/ins

however if my crv had it , i’d just wire in the jumper like the pilot guys have done to permanently disable it and call it a day.

While I share the general view of this being an addition not asked for or desired... I think it is premature to be condemning it before we even had a chance to see feedback as to how well it works for the mid-cycle refresh of the gen5 CRV.

Anyone that simply does not like it and does not want to use it, yet can't be bothered to use the disable button (one quick and simple press of the button after starting the vehicle, ... then I have zero sympathy for you. Some things in life can be complex or difficult.. this feature simply does not make the cut in my view.

Clearly... Honda is rolling this feature into every update of their vehicles... so it's coming to all Hondas... like it or not. Same for many other manufacturers. Owners either cope, or fall to the ground in fetal protest I guess. :)

Stop start is here to stay on most brands.i've only driven a few rental cars with it. To me it's not an issue. its also fun to figure out ways to fool the system...

The picture from a BMW shows a much better design and location for the "off" button. This is far better than the 2020 CR-V which is on the upper passenger side of the shifter console and harder to reach. Maybe Honda will learn.

Personally, I would not want the off switch located the way BMW does it.

Why? way too easy to hit the start stop engine button when it is co-located like that... thus forcing your auto engine off, only to have to restart it and then reapply the A-off button yet again. I guess it does have the merit of being a two button sequential process.. which is probably the way BMW sees it... but again... carelessness on the part of a driver will completely defeat the location chosen here.

BMW often tries to be just a bit too clever in some of their vehicle features. I also do not like that the modern BMWs do not come with an oil dipstick either... and you are left to trust the vehicle to let you know if you have an oil level issue via an electronic display of oil level. Given BMW thinks it is normal to burn through a quart of oil ever 1K miles... perhaps they went this route for the "never check the oil" crowd.

Yes, certainly a consideration. I would be a little cautious of the 1st year CRV Hybrid, understanding they already make an accord hybrid. We are considering the updated RAV hybrid, I have a 2017, but like certain aspects of the CRV better. Not sure what the CRV hybrid cost and availability will be? Thanks.

Personally I am done with Honda vehicles, between the CVT transmissions and the cylinder deactivation on the V6, they have nothing further to offer me. Start stop is just another annoying thing to eventually break. My last CRV was a 2014 while they still had normal auto transmissions with gears, no belts and hubs. Its been a good car so far, we got 51K on it now.

I just checked the 2020 specs on Honda’s website and they indicate the 2020 does NOT have “idle stop”

Time will tell if Idle Stop is here to stay; if the EPA revises the "credit system" it may well disappear.

"The real motivation is found deep inside the 1,500 pages that are the new U.S. Corporate Average Fuel Economy standards. It turns out that, to encourage the automakers to think frugally, the regulations allow for something called “off-cycle technology credits,” essentially a reward for incorporating gadgets for which the government testers can’t measure any discernible benefit in their laboratory testing but think will be of benefit to fuel economy anyway. There’s a raft of such doo-dads — stop-start, various aerodynamic aids and even high-efficiency headlights are included — that garner automakers credits regardless of their benefit.

In the case of start-stop, it’s an automatic gain of 2 grams/mile of CO2 reduction for cars, while trucks, ever advantaged by the American government, get a credit for as much as 4.4 g/mile. Throw the entire suite of accredited gadgets at a car and the benefit can be as much as 17.8 g/mile (for non-hybrid trucks), roughly equivalent to two to three miles per U.S. gallon. For an industry struggling to meet that ambitious 54.5-mpg figure, it’s a freebie few automakers can turn down even if they know the benefit to consumers is questionable."

No disagreement.

The ability though to reduce carbon emissions from vehicles sitting idle in dense urban traffic means ... Idle Stop is here to stay though, since it is no longer experimental and has proven effective and scalable across the industry now. California and 16 other states that follow California standards will effectively drive it's continued incorporation, precisely because it is effective at reducing carbon emissions in large urban cities.... and this is an easy one for the vehicle makers to tap as a step in that direction. For rural areas where there is no constant stop and go traffic, and low vehicle densities ..... it's not a real benefit in the grand scheme of things... but.... it also does not deploy that much either... since... little or no stop and go traffic.

Our new RDX has this feature and we gave it a try for a couple of weeks but just found it annoying as all get out. Now we turn it off as soon as we start the car, thank goodness Honda gives us that option. I would disable it permanently if it was possible.

I also have a new RDX ;-)

The following is directed at the members, not one in particular...

Not all manufactures give the driver the ability to disable Auto Idle Stop..it is good that Honda does.

I don't dislike AIS, but in the RDX, you can minimize it's actions by setting the HVAC temp to LO (or HI) while NOT using the AUTO setting....or by applying a lighter pressure on the brake pedal while at a stop...or pushing the button, which when you think about it is not really that big of a deal...You fasten your seat belt, turn the volume of radio up or down, set the trans in reverse or drive, release the parking brake..all muscle memories...I suspect the real issue is the lack of control of the "feature"..but you DO have control.

Perhaps I don't mind it because I have driven several hundred thousand miles in hybrids, and, while hybrids use a different system, with different implementation, and associated feelings in the cabin, I understand the benefit, and when comparing that with the perceived discomfort (if that is a reason for disliking it), I find that the benefits win. AND, FWIW, I am definitely NOT a tree hugger...LOL

Start/stop works great, you just have to get used to it. It's very easy once you get used to it.

If you have concerns about the engine wear, you need to remember that this was one of the oil companies' greatest ad campaigns. I'm sure you all remember the commercials about how "bad" it is to start/stop the engine and how you need to change your oil more often if you do this! Of course that's how most people drive their cars, so they were just trying to get people to buy more oil, and this one really stuck with people like an urban legend that doesn't go away.

Listen to the people who designed the car. They know what they're talking about and how to design the car to work well with it.

Also, I have a Volvo XC90 with stop/start, and in the summer it will start the engine while stopped if the AC needs to run. Car designers are not stupid.

My wife's 2015 MB GLK350 has the stop-start feature that I hate. It's just abrupt enough to notice every time it engages at a light. When I drive it the first step after I start the GLK is to hit the ECO-off button followed by the Sport button so it does not start from a light in 2nd gear. It's so second nature not that I don't even notice that I'm turning it off. Watching my wife drive I notice she does the same thing minus putting it in sport mode.
