Engine Start/Stop Vehicles

Yeah I know. But the number of those I have replaced is too many to count they are especially a problem on Toyota. I’ve only replaced maybe 3 ignition switches ever. When the push button start goes out it leaves you stranded it happened to some of my customers.
Or the pull rope:D

Only if it's the non-recoil kind where you have to manually wind it. Recoil springs can break!!!
 
The same thing that happens when your car just dies for no reason. Like the gallon of water in the gas you just bought. Other drivers might help you push it, or just sit and mindlessly honk and threaten you.

That said I work in the rebuilding industry, I look forward to these systems coming out of warranty so we can sell more parts.

You're right, but I'm talking about the start/stop system malfunctioning for no reason and causing a perfectly functioning car to die, just to save .000001 MPG.
 
Yeah but the button wears out faster after use. Much faster than an ignition would. The longest I’ve ever seen one last is 11 years till it had to be replaced.
Depends on what you're driving. My 2008 E-350 has keyless go and it's about 13 years old at this point. Still fine although the button on the shifter can have a wire break, but hasn't happened to me yet. The newer W212 model just has a button which you can just remove if the battery in the fob dies and use the key normally. It's always missing on a used car so they can be bought on eBay for about $15 if you have that option. It's aluminum so the button doesn't really wear out.

I see stop/start all the time in the city. Cars come up to the crosswalk and you hear their engine shut off and as soon as you finish crossing, it kicks on a few seconds later. That 5 seconds doesn't save too much gas.
 
Test drove a few '20 Souls with the I.S.G. and new C.V.T.. Didn't mind it . They are having problems with it on some new SOULS and I think the FORTE as well . Managed over 39 m.p.g. on display for 20+ miles that was mostly city . More likely 36 for calculated gas milage . KIA / HYUNDAI computers are off 3 > 4 m.p.g.. Still good .

It's a little more than that. But you can blame CAFE for that. They've been in Mercedes E class since 2014 and when they fail, it's usually the aux battery that goes bad and then the start/stop system doesn't work anymore and it doesn't shut off. People would like it that way, but then you have an annoying warning notice on the dash all the time so they end up getting it fixed. The starter just doesn't seem to be a failure point with that system. Because of CAFE numbers, they don't let you permanently shut it off, just for that particular drive cycle, have to turn it off every time you start the car. There are hacks to shut it off permanently, but they're not cheap.
 
I've been around and driven quite a few vehicles that have it. None have experienced reliability issues, but I personally don't like it just from a drivability standpoint. Some manufacturers implement it better than others, but there seems to be a very apparent stumble or hesitation with a lot of them when accelerating from a stop. This is more obvious with vehicles that have a hint of turbo lag on initial throttle tip-in.
This is where the 48V mild-hybrid systems excel. The battery also powers the electric motor. On my Ram, the electric motor completely eliminates the stereotypical lag during the initial throttle tip-in.
 
The push bottoms that fail are likely the result of users pounding the button or exposing it to drinks etc. Just like owners with weighted keys that affected the cylinder.

Generally speaking, people that treat their automotive investments poorly usually get poor results back.

On the start/stop systems, on a good modern car you cannot even hear the engine. This isn’t the 70’s.
 
I personally am not a fan of the auto start/stop. I've had several as rentals and some are better than others. The GM system in the CT5 and Buick Enclave is pretty good. I had a CT5 in San Francisco and something about sitting on an almost vertical hill at a stop light without the engine running when the light turns green was unnerving for me.. Glad my Ram doesn't have it. I think the first thing I'd be doing on any vehicle I bought with it (ones that don't do it are getting harder to find) would be figuring out how to disable it.
 
Adds a lot of internal engine wear from my days in the Dynos. Had to update the bearings in the Pentastar to get it to pass testing. As an OCD engine design guy, I shut it off. Saw too many bad things at the teardown reviews and on the CMM's. Screw the starter...I felt for those poor bearing surfaces! haha
 
This start/stop topic is one that is staring to appear on a regular basis. First of all-it's not new. It has been around at least five years. Are shops seeing failures of the components-yes but not in any large numbers.

NO-the the start/stop system doesn't use conventional starters and technology.

There are after market black boxes (for some vehicles) for less than $200.00 that plug in to the OBD ports that disable the technology as long as it is plugged in to the port.

I know there are those on here who run away like a scared cat when it comes to anything different or "new-tech".

You are going to have to keep your Crown Vics for a long time fellas.............

it's not that we are technophobes, it's just that this is pointless new tech that creates an unnecessary failure point. I love Apple CarPlay, backup cameras, EFI, auto-on headlights, as they serve a useful purpose. This tech is really just to game the EPA test and serves no other useful purpose.
 
What’s wrong with push button start?

Even my Tundra has the equivalent. It cranks until it starts whether I hold the key or not. It’s an auto system, like push button, not like I’m holding the key and energizing a hot lead to the solenoid.

Learned something new about my truck after almost 4 years! :alien:
So I can turn the key and let go. I will try it next time.
 
Europe has had start/stop systems for decades so there should be some longevity data related to start/stop systems and their impact on the engine. Some OEM's have "smarter" systems than others and thus do not stop/start unnecessarily. I can state unequivocally that Mercedes and GM (in the Netherlands) have better systems than some of those in the US. The system in my Jeep (FCA) is not very smart and stops far too often, but with that said, I have seen an MPG improvement when using start/stop versus not no matter which OEM it is.

I have a Tazer Mini that I will be installing at some point that will turn off start/stop on my Jeep so that I do not have to remember to shut it off each time I get in it.

Start/Stop saves fuel...if only during the EPA test or real world............................
