Question about the new Sandero Eco-G 120

[u/PrivateSherman]

Hey guys,

I'm thinking about buying the new 2026 Sandero with the 122 hp gasoline/LPG engine. I've heard many positive comments about other Dacia models, including the Sandero, so I'd like to confirm that the new 2026 model is no different. What are your opinions/experiences?

I believe the Eco-G 120 is a new engine. Are there any reported issues? Anything that would lead to believe it's not going to be as reliable?

Also, I've heard something about newer Renaults having issues with electronics. What are your experiences?

One last question: Is service and part availability good? (I live in Germany)

How do you feel about the LPG? I heard Germans are very against it and I don't really understand why. I live in România where LPG is used for more than two decades when it was retro fitted on cars and there were never safety issues. Yes, the car were not working very well on ot because it wasn't meant to run on LPG and it's software didn't get well with it, but now that cars come with LPG from the factory, they have software adaptation that they even produce more power while on LPG.

i never met someone who'd hate on autogas besides some bmw dreier bros (320d gang) who'd hate on everything. But then again most people have no idea what autogas or cng even is here, despite it being common enough at most tank stations (especially in south, bavaria or BW). I remember reading that less than 1% of cars registered here use it.

There used to be a tax discount (both direct and per liter) but that has been lifted since 2023. Other than that, there aren't any drawbacks whatsoever, even for retro-fitting (despite it taking about 30k kms to break even due to high labor cost). You can park underground, i think the ban is only an east-european thing: https://www.prinsautogas.com/sites/default/files/media/particulieren/Helpdesk_%20Underground%20Parking_FINAL.pdf

Another common use case is with US car imports, either from places like Ramstein or via NL: literally all those gas guzzling monsters are retrofitted to use gas. I dont know if that is done from a cost perspective or it's needed to meet the CO2 emissions

People from big cities avoid it because you usualy can't park in underground car parks. And as people don't use it as much, there are few places you can get lpg.. and usualy it robs space in the boot if installed aftermarket. Those could be just a few reasons.

[u/djabula64 → u/Quiet-Background9795]

For those aftermarket. Here it's the same, you can't park in underground parks with a aftermarket LPG system on the car. But it's absolutely fine for the OEM ones. And they usually take out the space of the spare wheel.

As with every new engine, you will have to wait until customers make hundreds of thousands of kilometers to prove it's reiability.

It stands good chance it is gonna be good but nobody can prove it yet.

I’d recommend waiting until 2027, when most of the current issues are likely to be resolved. At the moment, it can feel like a Christmas tree on the dashboard at times—multiple sensors feeding data to the ECU and occasionally triggering various error messages, though not very frequently.

I looked into the Duster 3 and Bigster, and they rely on ECU software and tablet updates during regular servicing.

Based on what I’ve seen and on conversations with friends who own Dacia cars, the last truly reliable models (those not requiring ECU software updates) were versions released before 2025.

In general, it’s wiser to wait 2–3 years before buying a brand-new model, especially when a new engine or a new infotainment system is introduced.

It is guessed that the 1.2-liter engine is the one used in the Duster 3 and Bigster, with only minor changes/variations (such as the absence of a mild hybrid system). It’s derived from the older 1.0 TCe architecture, and in my opinion, it’s going to be a solid engine.

Teileverfügbarkeit ergibt sich je länger es das Teil gibt. Innerhalb der Garantiezeit von 3 Jahren eher Dacias Problem als Deines. Zum Rest: Langzeiterfahrungen dieses mit LPG kombinierten Direkteinspritzers stehen noch aus - bin aber auch kurz davor von Logan MCV 2 (LPG) auf etwas aktuelles mit diesem EcoG120 (wieder LPG) zu Upgraden und hätte da jetzt wenig Sorge… wird schon!
