Stop/start Vehicles Wear & Tear

[MantaRay]

Is there any indication that the increasing number of vehicles with stop/start systems are wearing out starter motors and flywheel ring gears at a rate to be concerned about? I'm sure that the cost of such replacement would offset the cost of the fuel saved.

Manta....starters and flywheel rings are the casualties that first spring to mind..however oil drain and surface contact on the crank bearings becomes worrying over time.I expect it will cost the motorist a packet outside warranty.

...plus all the extra time the turbo will spend in a hot soak condition without oil cooling the bearings & shaft.

On the plus side, you give out less pollution don't you ? And savings aren't just to your bank balance but to the Earth's fossil fuel resources too.

not heard much but you will, something has got to give. Also, it is known that it takes at least 15mins to put back the charge needed for starting so surely these will just run down the battery in traffic. Incredibly bad silly unnecessary idea that does not save fuel. Mechanics shops love it, it gives them work, like the cam belt fiasco.

^^^several wrong, misinformed and silly answers above. All the "vunerable" parts are specially-designed and heavy-duty...even the battery. And lots of built-in safeguards to prevent battery drain (including regenerative braking).
I've had stop-start for well over three years on a new car...no problems at all.

you will ginger

How do you know that the starter motors/flywheels etc are uprated ginjebee? Those that I've heard so far sound pretty much like starter motors [albeit uprated] driving a ring gear that will wear regardless.

[ToraToraTora]

can't see how it saves any fuel anyway, it is well known that starting a car uses a lot of fuel compared to tick over.

Here is an interesting article about engine wear on stop/start cars.

You can always switch it off if you don't want it to operate.

[ToraToraTora]

yes, that is generally my advice chiaroscuro.
