1. I do after starting my car -switch off the start/stop automatic. Driving to my office 5 miles) I have to stop around 15 times (red light, stop- and go traffic etc) - it can't be good for the engine to bei stopped and startet so many times.

[@SketchRC]

Modern engines are built for auto start stop. Engineers know these issues and they resolve them by modifying oil pumps, starters, alternators, and batteries to cope with the extra cycles. I don’t understand why auto start stop is a bad idea, but hey, maybe that’s because I’m an automotive engineer and I know more than most people about this stuff.

[@erichg.6235]

OK, its good for the engine and the battery (aircon keeps running while start/stop is active, music and light is on) to start and stop every 2 or 3 minutes in stop-and go traffic. Even I stick an hour or longer in a traffic jam. Mhh, no, mr. engineer, i don't use start/stop automatic. In a year 1000 or more times starting the Motor, in 10 years more then 10.000 unnecessary starting the engine?

[@SketchRC]

beckys2222 By that logic, we should have hand cranks on all of our cars to start them. Things don’t just break randomly. An auto start stop will be designed for the same life as a regular starter motor system. It’ll break just as quickly as whatever you’ve got.

[@JakeWerkmeister]

I rented a 2017 Impala earlier this year that had this system. I was wondering as to whether or not they changed the starting system to compensate for regular wear. You confirmed my fear about these cars. Glad that I avoided that feature on my last vehicle purchase.

[@DaleC1980]

Yes they have beefed up the components but from what I have read, it may not be enough. Sounds to me like having a car with this feature and disabling it will be the best because then you have the beefed up components without the additional wear

[@DickDebonaire]

As bad as this monstrosity of a system is mechanically, it's the electronics that I would be most worried about. The engine will only stop after many sensors and computers talk to each other and report their parameters to see if it's a good idea to stop the engine at that given time. I'm sure I'm missing some but (both) battery voltages, outside temperature, cabin temperature, coolant temperature, oil temperature, whether the car is on flat ground or a hill, how long the car has been stopped and how much pressure is on the brake pedal, air conditioner or heater use, and any other devices drawing current. I'm sure I'm missing some. And if any one of these sensors or computer chips fail you'll get a service engine light at best and a car that strands you (or gets you in an accident) at worst

[@jblyon2]

A tech relation: Years ago IBM invented it's 'airbag' system for laptop hard drives. If a sensor detected vertical movement it would park the hard drive's read/write heads. This prevented them from hitting the surface of the drive when the movement stopped, which could destroy that part of the drive. The problem? Like that crankshaft, the drives were only rated for a limited number of park cycles, so while they didn't get damaged from drops/jolts, they died prematurely because the read/write heads wore out.

[@dinocrest1946]

My old HP one had that. Hard drive is dead now....

[@HunterShows]

Ironic.

[@jakegarrett8109]

Later, technology called the SSD completely eliminated that problem, meaning you could bolt your laptop to a jackhammer and the HDD would be fine with no performance loss. Tech may not be perfect the first time, but that doesn't mean it won't get there. My little quadcopter has over 2 HP (actually 2 kW), and the motors stacked would still fit easily in your pocket, not to mention the batteries it runs can start a lawn mower (or possibly a small car), and they can also fit in your pocket (I carry half a dozen in my jacket). Pretty sure you could just make a non-geared (brussless motor ring, about 2ft diameter) connected right to the shaft and spin up a motor almost instantly.

[@swabby429]

My best pal has a 2009 Prius going on 280,000 miles. The only thing that went bad is the ABS braking module. The battery replacement, earlier on, was his biggest expense, but he considers that cost as normal operating costs. It did take him awhile to get used to the stop/start characteristic of his car.

[@gregoryfaulkner5345]

Yeah they all have limits to how much and how frequent and for how long they'll shut off, but they can still be annoying in extra urban traffic. To me the best solution to control the start stop would be brake pressure with a foot- felt click. Drivers usually know when we don't want the engine to shut off and when we do. We're watching lights and traffic in front so we can predict the worthiness of an engine shutdown. Ford F150 has an override button, but it has to be remembered and it resets when the key is turned off, so not ideal. Most of them have tricks one can do to override. Hook up a false trailer connector, turn on regular a.c. versus hybrid a.c., go to tow- haul mode, defrost, etc, but none of those are ideal. Best if we control at the brake. We can always remember that and keep our attention on driving. Self driving is science fiction for when we colonize Mars. This is what cell phone prioritizers want, so they can go from mostly distracted driving to being totally distracted.

[@JamesSmullins]

Yosef MacGruber this is a lot further off than companies like tesla want you to believe. In order for self driving cars to work they need perfect well marked roads. If the lines are faded, covered up or in any way not absolutely perfect the sensors can't read them. This has been the failing point every time as is it's ability to deal with other vehicles around them changing speeds. Changing lanes for example is risky if a vehicle in the other lane decides to accelerate. I also suspect self driving cars will actually slow traffic as they will force larger spaces between vehicles and during turns at intersections fewer cars will turn per light cycle. We humans will hurry through to make the light but the safety measures of a self driving car will not. The end result may well be worse traffic.

Toyota must be laughing to the bank with all that extra starter cash they'll be making. If they cared, they would make the starter motors brushless so that they dont wear out with so many uses, but that would be expensive. It's easier for them to use old-fashioned start motors so that you'll send it back to them so they replace the brushes and sell it back to you at full price.

[@andrewcimochowski]

[@St1ngerGuy]

I just got a KIA Stinger with this and it does have a button to disable it. For the stop/start to work though specific conditions have to be met or it disables itself. Engine has to be warm, AC can't be on (wont work without the compressor turning) and the coolant can't be too hot either. It also monitors the batteries current charge and if it drops below 73% it disables start/stop. The next cool thing about it though is it doesn't start the engine when you press the gas, it starts it when you let off the brake. You can let off the brake about halfway where the car will start but not move yet so you can anticipate lights and have the engine ready to go. I have to say it's about the least intrusive stop/start solution I've seen and it starts super quick. To top it off if you stop when you pull into your driveway and the engine shuts down you can just push the stop engine button and it puts the car in park and doesn't turn the engine back on. Bottom line, there are different ways to tackle some of the issues with stop start, and manufacturers are using these technologies to make it reliable and as least intrusive as they can. If it saves some gas and maybe some pollution why not give it a chance?

[@chevalierjd]

I just bought a 2019 Toyota Highlander XLE with this feature. When I took it in for the 5K checkup, I asked the mechanic if start/stop would hurt the vehicle over the long term.

Now I am certain to deactivate it everytime I crank her up. Thanks Scotty!

You're right Scotty. All those things do is allow the manufacturer to boast better gas mileage on the sticker. On our BMW's I was able to code them to stay on. I was thinking, "these starters are not easy to get to and replace and I'm not wearing mine out by saving a couple bucks in gas!".

*Thanks for confirming what I suspected from day one* . The first time I saw a car with a stop/start idling feature I was thinking: "Boy, all that stopping and starting is going to be hard on the engine." Good to know from an actual mechanic that my intuition was right. My impression of most car buyers is that they're stupid. If you tell someone they'll save 3-10% on gas mileage, I guarantee you most of them won't look any further into it. Most consumers are trained to accept the first number thrown at them and most (maybe as high as 95%) do no further investigation and no further questioning beyond that. They're well trained sheep. Since I know a little something about engines and electronic equipment, I know that the stop/start phase is the most taxing on the system. Engines work best when you start them, let them run a long time, and then stop them. Constant stopping and starting damages the motor. I don't have any vehicles with stop/start anti-idling features in them, but I've driven cars with them before and find them annoying. The moment that feature came out, it was added to my list of "features to avoid" on new cars.

[@siskiyouwoodsman4279]

Been a mechanic for over 50 years and overall I agree that these start stop systems are going to cost the end user big time! That being said, I can’t agree with the start stop causing any measurable wear to bearings, even over an extended period of time as the parameters under which they work are the best conditions for a restart ie engine warm and oil less viscous and able to reach full pressure almost instantly. There are plenty of legitimate reasons to not have these systems the most important being premature starter and battery failures not to mention leaving one stranded in traffic which in my opinion could be dangerous. Just purchased a new GM vehicle that has the system and it can not be turned off, but I’ve found a way to defeat it without throwing a code or throwing off any of the other systems. I pull the gear select lever into L when I stop and then when traffic starts moving, I simply shift back into drive before taking my foot off the brake and presto, problem solved as the transmission must be in drive for the system to function.

[@LawrenceMarkFearon]

Genius. Thanks👏🏾👏🏾👏🏾

[@OssxJah]

Good idea, but you still moving your tranny around, sliding up and down every traffic stop. Not efficient and will again wear out the tranny. Next thing you know, it will start slipping. You can turn the start/stop off, but it's back on again the next time you start your car.

[@bruceh3786]

As mentioned, at least some of the GM vehicles do not have a switch to turn off the system. However I found that in the previous gen Malibu I have, it can be controlled by the amount of pressure on the break pedal. Just before the car comes to a complete stop, I can back off the pressure (but there is still plenty to stop), the system will not engage. I will do this for stop and go traffic or a stop sign. However when coming up to red light that just changed and I know I will be stopped there for a few minutes, I keep more pressure on the brake pedal and the engine will stop. Works well and is easy to do. My preference would be to not have the system at all.

Scotty. I appreciate your rant here! I have decades of automotive repair experience myself and I agree with you completely.

But every good mechanic knows that emissions are much higher immediately after the restart. What a load of garbage! Thank you for educating our young mechanics.

Auto-start systems usually have a defeat button to turn that mode off. BMW usually activates this mode when you go into Eco-Pro, but you can easily switch the start/stop off with a push of a button where the key ignition usually goes.

[@gravemind6536]

More batteries and starter motors to fail. I can't imagine its great for the engine either. The system is also useless when its at either heat extremity outside, In California it would be useless because everyone has AC on all the time and the heat outside is stressing the battery anyway. In Winter its useless because everyone has the heat on in their cars and the cold outside is stressing the battery. You have to have a very moderate climate for it to work well and this is also true of the new Tesla electric cars which operate best in temperatures of 20 degrees Celsius.

Electric oil pumps implemented in engines that have "stop start", reduce the excessive startup wear dramatically.

[@judgeadvocate9275]

So... losing a hand is better than losing an entire arm?

[@FierceMotorworks]

Independent tests have shown this tech will only save ~10% on fuel usage, in conditions where you stop and idle a lot. So is it really worth it to save a few bucks worth of gas, versus a bigger repair bill and more expensive starters/batteries?

[@judgeadvocate9275]

Belts also stretch every time the car starts. The engine oil goes back down into the oil crankcase every time the engine shuts down, making more wear on the cylinder walls when the engine restarts.

[@leerothman7570]

With due respect there are several manufacturers (mostly European) that have circumvented all the weaknesses of the system of Start/Stop. VW/Porche/Audi is one. Smooth as can be operation virtually seamless and do NOT compromise the longevity of the starter nor alternator systems and don't compromise the cooling systems either. The American cars I'm sorry to say are more so the one's that have compromised designs. My 2020 VW Tiguan has it and it's remarkable and so smooth, quiet and virtually unnoticed in operation. This has been confirmed by a neighbors son who is a top VW mechanic for a big dealer who explained this all to me. Said he has to date NEVER replaced an alternator nor starter for any VW over the last 4 years. The technology has at least come that far.

[@JHKCF]

Regardless if the manufacturer says the components were designed to seamlessly and reliably start and stop the engine, the more you use it the faster it will fail. So I’m shutting mine off every time I start my car up.

[@NewsFlashJustIn]

I've heard the purpose is to reduce emissions especially in cities and not to save fuel. Also isn't it only cold starts that cause the wear? When the engine is warm I thought there is hardly any issue?

i think that too. and i am a car mechanic. i have never heard that startups would make the roadbearing go bad.. i might be wrong but i highly doubt it

[@sammolloy8129]

The idiots who time the traffic lights and fail to keep building enough roads want your car to wear out so you ride the “mammy wagon” with the rest of the peons. Then they will have less traffic for their big fancy cars

[@judgeadvocate9275]

Let's pretend there's no wear on any moving parts with every startup... like belts stretching... like timing belts stretching. And when it's warm, the belts will probably stretch more. Replacing timing belts and tensioners aren't cheap. Water pumps are also not cheap.

[@WAN2TREE4]

In my Camry hybrid when you stop, the engine stops too then the battery takes over when you are in low speed. The engine kicks in when you press hard on the gas to go faster. That transition is normally seamless, you won't notice it although at times you will feel a very mild jolt when the engine kicks in, as if running over a small pothole.

[@wesjohnson5019]

You will know when the engine blows

[@cloudstrifeification]

Scotty, maybe you could do a video that shows us how to "permanently" disable this system!!

[@poopipeboy3033]

A cheap fix is to permanently jam the button in using some paper etc. Not an ideal fix, but it works.

[@gojoe2833]

[@OfficialistDave]

There's plenty of oil on the crank and bearings during normal operation. It's not a cold start. If it was an issue it would effect hybrids just as much - regardless of how it's restarted. Modern oils are more than capable of making this a non-issue.

[@wesjohnson5019]

It's still going to cause issues

[@pdongy]

Viscous film is nowhere close to oil pressure. And how many high mileage Priuses do you see? As many as my lot has sent to wholesale I would say it's a safe bet it does affect hybrids as well, we rarely send one out for a bad battery.

Stopping engine also stops oil circulation. When that happens, oil starts to boil in hot areas, example in turbos. As that happens over and over again you will contaminate the oil and get carbon deposits on those spots

this is one time i'll disagree with the kilmer advice... it's not a computerized starter motor engage type of system... it's a sophisticated torque converter that winds up when you're stopping with enough force. a solenoid engages the device and your car will shut off close to the stop when the device is wound.

[@kkampy4052]

Milton Friedman talked about the government mandating technology like this. He said these thing raise the cost of a car significantly and raise it out of the range of a lot of the population. He said it should be up to the buyer to decide if they want that and the secondary resale market will drive the sales of these systems. If people looking for used cars want this technology, they will only buy cars with it and that will drive new buyers to opt for these systems. These systems add $1000's of cost to new cars.

[@roningram5877]

Milton Friedman is a proponent of Unenlightened capitalism. I'm really mixed on stop/start, but I'm NOT mixed on the need for my neighbors to not burn tires on their residential lot. In a society of 10 individuals, with no outside contact, an economy and society based purely on the physical strength of one individual with the power to dominate his tribe would work. Of course everyone else would be looking for a way to achieve social justice.

The start stop is widely used Coz of the new pollution regulations, without this and reducing cilinders they won't hit the pollution mark required in EU for example.

Ah yes, fleet fuel economy. The pressure on car manufacturers to meet stricter and stricter standards is great. 3 % improvement doesn't sound like a lot, but if a car manufacturer can use this to improve economy just a little more, every little bit helps. Remember the Cadillac Cimarron from the 1980s? It was essentially a Chevy Cavalier with a more luxurious interior. Wasn't really a Cadillac, but it did help with fleet fuel economy. Perhaps ironically, better fuel economy is probably not the right approach to save energy. Cities built around car dependence probably is. If cities were built in such a way as they are in many places in Asia or Europe, most errands could be done either on foot or by train. A car is something that could be used a few times a week for recreation or on a long trip - which is actually a far better way to enjoy a car! That way, people would drive much less, overall fleet fuel economy wouldn't really matter, and we'd use far less fuel overall!
