Hey,

So I've got a bit of a strange one and I'm stumped, just wondered if anyone had any ideas...

So basically when my 2012 Rio has been sat overnight or for a while and is cold, when I pull off my drive and get to the end of my street and climb a small incline, and change into 2nd and put my foot down, the engine feels like it's losing power and then if I keep my foot down it makes a clunk and I feel a shudder from the front, however, if I change into 3rd it doesn't do it and is fine again. Plus, once I pull out onto the main road, and it's driven for 1-2 minutes the issue isn't there and it drives perfectly then no issues.

Initially, me and my mechanic thought it could be a faulty DMF as I also get some chattering, however apparently after some digging I don't believe these have DMF and are Solid Mass. Since the problem goes away when it's warmed up a little it can't imagine it's engine-related or a mounting issue otherwise it would do this all the time. So it obviously seems to be something transmission-related as it only does it when in 2nd, cold, and when torque is on it.

I have also tried replacing all the plugs with new NGK's just to rule out a misfire issue.

Beginning to wonder if it could be the Solid Flywheel and/or drive-shaft or something along those lines.

Anyone get any ideas?

Yes, solid clutches, no dmfs in Rio.
Sounds very much transmission related.
I would check the gearbox oil level, but sounds clutch related eg slipping causing power loss then shuddering when it re-engages.

The clutch is relatively new apparently, however it seems strange that once it's a little warm, the fault goes and it drives perfectly. However, the clutch does chatter when it's cold too, and again that also goes when it's warm. Strange.

Keep an eye on the tacho rpm whilst accelerating. If rpm rises whilst losing power, then transmission related. If rpm drops then look at engine.
