Will it be possible to permanently deactive the start stop feature on the V6 2015 Cherokee?
Note: I understand there will be a button to push after you have started the car to deactivate the feature but that it resets at every new start (and that is something that I do not want to do each time).

I don't know the answer to your question but I am sure glad I bought my 2014 Jeep Cherokee Limited 3.2L last November. I sure don't want to be dealing with that stop and go stuff. I value performance over a minor gas mileage improvement, if any. I think this stop and go stuff will be one more piece of technology to go wrong and cause problems. I finally have my 9 speed transmission operating the way I want it. Just imagine coupling the two problems together.

I just ordered my new Trailhawk and was pleased to learn that it will include this feature. I have it on my MB E350 and it really does save fuel. I get on average 8.4ltr/100kms (28mpg/US Gal) which is great for a 3.5ltr V6. The only time I turn it off is when I'm in slow rolling stop and go (creeping) traffic and it's no biggie to simply press a button. With it engaged the engine starts before I can get my foot off the brake pedal. I would say I use it 98% or the time. I'm not sure how it works on the Jeep but on the MB it isn't active until the engine warms up.
It's incumbent for manufacturers to lower their fleet MPG level, that is basically why Mercedes sells the Smart car. They don't sell a lot but it helps lower the fleet MPG rating.
As far as one more piece of technology to go wrong, well really vehicles nowadays are loaded with technology, with that attitude we should stop buying vehicles altogether. Having said that I only keep vehicles for 3-4 years so they're usually fully covered by warranty.

I`ve droven many cars with start stop. In Europe its an standard for new cars, years ago. The mileage you can win isnt measureable. Unless you got stops over 5 mins. If you like it use it . I`m only using it in Hybrid cars. Stop, motor turned off, green starting with electro, while hearing the BMWs and MBs starting.

I recently test drove a Volvo XC60 with a 2 litre 4 cylinder engine that had the "Stop-Start" feature and I was impressed. There was no shudder and after only a short time of driving I got used to it. On start-up it was very quick, quiet and smooth.

Jeep's claims that the "Start-Stop system will feature a High Speed / High Durability Starter and beefier Batteries. When the brake pedal is released the 3.2 litre V6 will re-start and the nine speed automatic will re-engage within 0.3 of a second". (source: CarAdvice Australia)

Personally I'm looking forward to this feature and have high hopes that it will work as claimed. I'll wait until I actually drive the Cherokee with this feature before passing judgment on it. It's what we do "Down Here"; we like to give most things a "Fair Go". Well done Jeep for being so proactive with all the great features and technology of their new Cherokee.
