Seeking Advice on 2021 Renault Arkana Hybrid Electrical Issues and Potential Terminal 30 Interruption

Dim or flickering lights

General electric malfunction

Weak battery when starting the engine

Hey car geeks, I've run into a weird problem with my 2021 Renault Arkana Hybrid. Lately, I've noticed some electric snags, stored faults, less than brilliant lights, and a pretty lifeless battery at start-up. I suspect it might be linked to the interruption of terminal 30, but I'm not entirely sure. Have any of you had similar issues? If so, how did your local workshop diagnose and fix it? I'd really appreciate your knowledge and experiences. Cheers!

Hey there, sounds like a bit of a problem you've got there. Let me share a similar experience I had with my 2017 Renault Kadjar - close in age and from the same brand. I'd consider myself having some experience with cars, been tinkering around with them for years now. In my case, my ride also had power issues; super dim lights, and a lifeless start up. I took it to my trusty workshop, and after some checking, it turned out to be a case of a dodgy battery. For the diagnosis and replacement, I paid about 290 euro. Sorted my issues, and it's been running smoothly since then. Before I can share more, could you tell me more about how you use your car? Is it often parked for long periods? Or are short rides more frequent? Any specific modifications or aftermarket additions? This info will help provide some more context. All the best.

Hey, thanks for sharing your experience. To answer your questions, I usually don't park my car for long periods - I take it out almost daily. Although they're usually short urban trips to the office or store, I occasionally enjoy long highway drives on weekends. Don't have any major mods or aftermarket add-ons, just a couple gadget type things for convenience, you know. As far as I'm aware, there haven't been any issues until I hit the 173,765 km mark shortly after the last service. That sounds like a pretty spot-on comparison you've made there with the battery. 290 euro is manageable if it means a smooth ride again. I hope it's something as simple for myself too. Cheers for the insight.

Howdy again! Your usage sounds pretty similar to mine, especially the mix of short daily trips with occasional longer ones. After reading about your case again, I'm getting more sure that it could be your battery. Usually, short infrequent trips don't give the battery enough time to fully recharge, leading to gradual drain over time. That's where the weak starts and dim lights might be coming from. Repeated cycles like this can harm the battery health over the long run, especially when you're hitting higher mileage like on your Arkana. I'd definitely recommend getting your battery checked out first. If it turns out to be the culprit and you get it replaced, that should take care of your electric snags and stored faults. Your response clears out a lot of my initial concerns about terminal 30 interruption. In case a new battery doesn't solve the problem completely, the next place I'd look will probably be your alternator or the wiring circuit. But fingers crossed it doesn't come down to that. Head over to your local mechanic, and keep us updated! All the best with the fix.

Hey there, brilliant advice! I had a sneaky feeling that frequent short trips might be punishing on the battery. Now that you've mentioned it, it makes total sense, so cheers for the explanation. I will do as you suggest–get the battery looked into first, and then consider the alternator or wiring circuit if needed. Will definitely drop an update here after my visit to the mechanics. Fingers crossed it's a simpler fix. I appreciate the help heaps. Cheers!
