2020 Renegade Issues

puddlesplasher said:

My manual Renegade has auto start/stop but I keep it turned off. On occasion I must accidently hit the switch and sh1t myself as the car jumps into life at traffic lights.

You're lucky that yours stays off. On the US models the start/stop defaults to ON every time you start your Jeep.

George since I first seen it's conception many years ago in an old VW Polo that my Bro In law was driving and it left me dismayed and bewildered. Having a car run as normal and then shutting down on me was an alien concept. It is still alien today, to me.

Why on earth does anyone want a vehicle that stops and starts? Stop, stop guys. I don't literally mean that.

I am old school in the way that cars were made. It starts, it runs until you turn it off.

On this occasion my Jeep is the first car vehicle I have had with this function. Some like it, I don't.

I feel your pain!

So the UK (or Euro) models are different that way? You can disable the auto stop/start, and it stays off even for subsequent trips?

Not so in the U.S. ... You can press the button to disable for t he current trip only, but then have to press it again for subsequent trips.

And how does it work on your UK manual? Does it start the engine when you lift off the brake pedal, or when you engage the clutch, or when you press on the accelerator? I believe ours (automatic only) do it as soon as you release the brake...

Well, auto stop/start isn't turned off all the time -- it has to be turned off by pushing the button for each driving cycle.

With it turned off, there would be marginally-higher fuel consumption, and maybe marginally-faster acceleration from a stop.

Do current manual-transmission Renegades have this?

Just in case you were wondering. According to the OBD my average is 26.7 MPG for the last 158 miles.

I don't use it but here goes from my recollection.

Slowing down as I approach traffic lights and come to a stop. The engine shuts down to whatever start/stop mode you all call it. Raise the clutch with the accelerator and the engine kicks into life and the cycle starts all over again.

Centre column (UK) left side is the switch is the push/pull switch to engage/disengage.

Once disengaged it remains permanently off until actuated.

So with your UK manual, you have to release both the clutch and the accelerator? Or just one or the other?

Yeah, they recommend this because they use cheap oil and more changes means more money. If you use good quality synthetic and a matching filter there is no reason you can't go 8 to 10k between changes.
I am sympathetic of the transmission problem. Keep in mind that any new vehicle has the potential for these challenges. Have heart and good luck working it out.

Mine requires 100% synthetic (2020)

Further on the shifting...mine is automatic 1.3 turbo 2020 so it seems to me the brake acts somewhat like a clutch? make any sense? I was never great with manual as a teen so have always went with automatic trans. I tried to pay attention today on busy rush hour traffic drive home. If the brake is not pressed down hard it does not go into gas save mode I have learnt how to maneuver it just so, kinda like a clutch, I imagine. I have never turned it off and would have to figure that out...but instead figured out how to work it.

This is the way of the future like it or not...to save gas😉 In US it will only get stricter and stricter to comply with EPA and energy use guidelines.

I have to turn my stop-start off every time you get in the Jeep but thats not a problem because it aint worked in months.

Wait...what? We're slightly off-topic here, but I would certainly expect that a Jeep dealer would use the weight and specification of oil that Mopar recommends/requires; particularly since it could be a warranty issue. That would be MS-13340 for a 1.3L engine, and MS-6395 for a 2.4L.

Of course, it might be a challenge for a dealer to keep both of these and more in-stock in bulk, and keep them straight; but that's their job.

That's one reason why I always* change my own oil -- to know what goes into the car. I stick to the specs, because I'm not knowledgeable enough about oil specs to deviate from what a manufacturer recommends/requires...

Once I get my on-order Renegade Trailhawk in mid-April, I do plan to * sigh * take it to the dealer for whatever free oil changes they offer -- but I'm going to be very careful that they show me what spec oil they're putting in.

Yup. And I would have expected the default (or even mandatory) auto-stop/start feature would have been introduced in Europe even earlier; because of their price of fuel and, um, higher eco-consciousness (just ask them... ).

Of course, tests have shown that the fuel savings are very marginal...

Amazing if stricter and more Eco conscious than CA! 😮 Btw I am getting at least a couple more MPG overall than my 2016 Limited even with the added weight of TH package
It all adds up I guess, to save the planet for our children (grandchildren)

Well, European prices for fuel are certainly astronomically higher...

True but CA is the highest in the states.

If I am in neutral then only raise the clutch. However I tend to sit in 1st gear and will stall the engine if I don't use the accelerator whilst raising the clutch.

Sitting in neutral is fine when I am not being a boy racer

Check your battery, the auto start/stop usually stops working when that tiny battery fails. I had this happen on my old Chrysler Pacifica minivan and one day. after months of it not working, the van wouldn't start at all. that battery is how the vehicle always starts.

Which tiny battery, where?

I was trying to find it, but I do not see it's actual location. I can say for sure that it has it though.

Why in the world would the auto stop/start circuit need a small battery?
