I am awaiting delivery of an extreme hybrid jogger. A colleague collected theirs before Christmas and it is now back in with Dacia for the 3rd time as it keeps cutting out while driving. Apparently the fault can not be found.
I have been searching for others with this issue as my colleague says they know of 3 others, but have only found one or two online that are yet to be resolved.
So I'm wondering if anyone else has had or heard of issues with the hybrid cutting out? My colleague has recommended cancelling now before delivery but I'm wondering if that's a bit OTT?! Although it is making me nervous.
Thanks.

I dont think such data is displayed anywhere except diagnostic tool (externally).
I have my rule of thumb about that which might be wrong too.
If engine start it will shutdown when temperature is high enough to sustain usual start/stop eco operation without self-demaging in the process because it is cold.
having that in mind i keep car ON until engine shutdown for first time in the morning even if i reach destination. after that point it is fine to start stop as many times as necessary.
Another indication engine is cold is if you turn off cabin heating and engine did not shutdown while you are standstill and battery level is normal.

When going uphill suddenly a “metal” noise is coming either out of the gearbox or the engine. The power indicator is 2 or 3 cm above the “power” word. The car is either at high revs or the gearbox is not selecting gear or something else …. I can’t understand clearly what it is because I immediately release the gas petal when I hear the sound. Does anyone else experience this sound?

...this is peculiar: i was starting to think that buying a non-hybrid Jogger was a mistake (see gearbox issue threads), but now there are a few folk having problems with the hybrids too...

...hopefully any issues with either drivetrain will be resolved under warranty...

We had a Jogger Hybrid from new, after 5000 miles it had a complete electrical system failure, the garage said it was fixed by installing the latest software. It happened again when driving home, complete freeze up....managed to roll to a safe place, steering almost locked. We lost confidence in the car but as we had had it just over 6 months we were fobbed off...They would 'fix' it that's all. The mechanic said it was a rogue car.....loved the car but its gone now at a big loss.

First thing I would do would be to check the 12v battery.

There are many complaints about hybrids / EVs from every manufacturer about this problem and almost all of them come down to the 12v system in some way. On an ICE, pulling 400 amps shortly after climbing in gives the battery a stretch and you can hear audibly if the battery is low. On a hybrid or EV, the smaller 12v battery can drop to unsustainable levels of charge without you noticing. Peak demand might happen into the journey causing everything to shut down - or it might affect a number of different unrelated systems.

The general advice is to carry out preventative charging - and always carry a booster pack with you in the glove box, although I've not done either of those things yet... I will probably get one of those cigarette lighter voltmeters though as a guide to SoC.

Other advice is to ask for the master tech - who may not even reside at that dealership - to diagnose the issue. Any idiot can perform a software update and claim it's fixed... ;)

I have noticed plenty of one post wonders posting about “problems” and never returning.

All new cars can have issues - parts quality seems to be an industry wide issue, my son fixes cars for a premium brand for a living. I would be p***ed if I had spent £100,000 on a car and it leaked or the infotainment system failed or it kept cutting out - believe me it happens…

My own experience has been extremely positive - my new Jogger is even better than my Logan was - and despite being significantly bigger than my last diesel MPV, yet it’s both quicker and 35% cheaper on fuel.

YMMV

You need to remember that this is a hybrid not an automatic.

The car maintains the state of charge - there is no “second” or “third” in the conventional sense because the output from the engine is also being diverted to charge the traction battery. You don’t control the “gas pedal” as such - you are simply commanding how much power you want delivered. If you demand power which isn’t available from the battery the engine will run at whatever speed it needs to in order to drive the HSG then spit out the remainder either from engine to the wheels (parallel hybrid) or battery to the wheels (serial hybrid).

At very low SOC and on a steep hill you are now bouncing off the laws of physics.

I suspect the only way you could fully 'solve' this isn't in software - it would be by having a larger (and more expensive) HSG and larger battery - meaning you could run in serial model almost indefinitely even when on a slope at very low SoC. This would be closer to the Nissan approach with their e-Power cars.

How to drive hybrid vehicle on steep slope road uphill

1-If there is a slope in front of you, do not try to maintain its speed on the slope, let the vehicle slow down until it reaches the top of the slope. It will support you if your battery is full in intermediate accelerations while going uphill.
2-Try to enter the slopes faster from the beginning because due to the e-CVT transmission, you do not have a chance to reduce the speed from the middle of the slope and step on the gas, the first part of the power section is sufficient when you loosen the gas from time to time and press the gas again, both the cry of the engine decreases and you get out faster by consuming less.
3-If you are patient while driving uphill, if you keep your foot in constant gas without giving too much gas to the vehicle, you will see that it accelerates without increasing its revs, the reason for this is that the electric motor draws energy from the battery and supports you.
It is not possible to climb better in this engine with CVT transmission and Atkinson cycle, but if your battery is at least 50-70% full, you will see that it receives electricity directly from the battery without charging when going uphill.

Today, I was able to climb that steep hill without making my hybrid vehicle scream. Style needs to change. That grumpy use goodbye... Otherwise the steep hill climb in the city with a hybrid vehicle would result an engine that screams differently and maybe eventually malfunction.
Edit: Today, I quickly increased the battery level by pressing the E-Save button. In this way, I went to the ramp much more comfortably. While the E-Save key was active, the engine gave priority to filling the battery and immediately returned to EV mode when 3/4 was full. This process happened in 1-2 minutes. Essentially, the vehicle is great with its integrated power. You feel the 140 hp integrated.

There are 15 gear combinations and infinite adjustments for engine power, motor power and HSG demand - alongside near-instant synchronisation in shaft speeds in order to not need any clutches so I think it is unlikely a single human could drive “manually”.
They say that there is no such thing as a stupid question, so here is one. Disregarding reverse gears, I thought that there were 3 gears for the ICE and 2 traction motor gears so surely that would give 11 forward combinations + neutral. So having said that, here is the possible stupid question: Where are you getting 15 from?😏

Four speeds for the ICE. There are many possible combinations of the three dog clutches, only 15 are valid. With only one ratio to the small HSG - that is why our friend is complaining about high engine revs to run slowly in serial mode uphill.

After a certain point, the software only needs to activate the output with the 1.6 engine. An electric motor that is always waiting ready (even if it is weak at that moment). Brother, you don't have power, you are still trying to support the 1.6 gasoline engine. Instead, we say okay, if you are very eager, let's prepare you too with the E-Save button. I can predict this on the road I go every day, but what about in cities I don't know???

Let me also mention a problem with the gearbox – I own a 1-month-old Dacia Jogger Hybrid with 1,500 miles on it. This morning, when starting off, the engine engaged first gear but struggled to disengage – the car jerked forward and backward about 5-6 times before it shifted from first to second. After a while, it also had trouble engaging first gear, accompanied by a horrible grinding sound, as if you're trying to engage first gear in a manual transmission without pressing the clutch. This is disgusting; I didn’t expect this from a brand-new car. I know Dacia isn’t one of the top brands, but I was still hoping not to have any issues, at least while the car is still under warranty.

So, the dealer didn't find any faults after yesterday's inspection. They told me there are no ECU fault codes, and the car was also tested with a 30-minute drive with no problems detected. Before driving the car, I added two issues to the list of problems—the first being that the wipers stopped working in automatic mode and only functioned on a timer, and the second, which is quite serious, is that twice the brakes lost servo assistance—the pedal becomes stiff and stays stuck in the up position, requiring a huge effort to start braking. The dealer said there’s no problem. I tested the wipers since it was raining when I took the car, and consequently, they do not work in automatic mode. Apparently, I’ll have to get used to these issues and fix them myself, just like with my previous car—a Škoda Karoq. After the dealer started ignoring some problems, I began addressing them with diagnostics, and apparently, with the Dacia, I’ll have to proceed the same way

I commented on this thread in January when I had just gone through 3,000 miles, trouble free. I am now 8 days off a year of ownership and just about to go through 22,000 miles, and still trouble free. As I stated in my earlier post you always be the odd car in a production when things go wrong but I haven’t heard of any issues on the hybrids on any of the forums I am a member of. And still getting circa 70mpg on my commute to and from the office when I go in!

I finally sorted out all my problems with the Jogger, returned the car to Renault - Perry Barr Birmingham, and got myself a Duster. The Duster is definitely on a higher level – same engine, same battery, and drivetrain, but built better. I’m not saying it’s a perfect car, but for the price, it’s pretty good. In comparison, the Jogger is quite overrated – for the quality it offers, it should be sold for a maximum of 18k, at least that’s its price in Europe.
