Seeking Advice on Troubleshooting Renault Arkana 2021 Hybrid Engine Problems: Possible Crankshaft Sensor Issue?

Hey there, I had a similar issue with my Renault Kadjar 2019, yet another model of the same brand. I'd say I've got some experience with car issues, having dealt with my fair share of them. The symptoms you described such as the unsteady engine performance and the sudden power loss were almost identical to what I was facing. Turned out, it was precisely the Crankshaft sensor wiring harness/connector which was defective on my car. So your hunch might be on track. I had to take it down to my local workshop. The mechanics there are pretty reliable. They diagnosed the problem quickly and did the necessary to replace the faulty wiring and connector. In my case, the total cost came around to about 170 euro. Now, to guide you more accurately, could you please provide more specifics? Like how many kilometers/miles your car has run, its specific model (is it the E-Tech Hybrid 140?) your car's current condition, and so forth. With these details, maybe I, or someone else here, might be able to help you out a bit more confidently. Hope it gets sorted out soon!

Hey there, appreciate the quick response! Glad to hear that someone else has faced a similar issue, helps me breathe easier. Onto the specifics, my Arkana is indeed the E-Tech Hybrid 140 model. In terms of the car's condition and mileage, it's done 181044 km so far, and I haven't experienced any major troubles until this cropped up. Got its last service done recently. Sounds like I need to get this checked professionally, does it matter if I head to a Renault service center or any common workshop would do? Also, any hints on what I can expect in terms of total costs? Not expecting an exact figure but a rough estimate would help. Thanks again, and fingers crossed it's just minor trouble.

Well hello again! Looking at the mileage, it's quite impressive for a 2021 model I must say. Now coming to your query, given that it's a relatively new car and a hybrid at that, my advice would be to take it to a Renault service center if possible. They would be better equipped to handle specific issues related to this model range. As for costs, it could really vary depending on the extent of the repair needed. In my case with the crankshaft sensor, I paid about €170 as I mentioned earlier. However, if the sensor itself is fine and it's only a matter of connection issue, the cost could be somewhat lower. On the contrary, if there's another more complex issue behind it, costs could cauterize your pocket a bit. Whatever be the case, brace yourself to shell out at least a couple of hundreds. And let's hope this issue is confined to the sensor or it's wiring only, meaning it won't burn a big hole in your pocket. Dropping it off with the professionals ensures accurate problem detection and remedy, although it also comes with its own costs as you'd well know. Long story short, have it looked at ASAP. Hope that gives you a bit more perspective, and don't worry - we'll keep our fingers crossed for ya!

Thanks a ton for all your invaluable advice! Really puts my mind at ease. Taking your suggestion on board, I'll tow my Arkana down to the Renault service center first thing tomorrow. Here's hoping it won't need anything too debilitating for my wallet. But you know how they say, 'better safe than sorry', and a stitch in time may save me nine (and a chunk of cash hopefully!). I'll keep you guys updated on how it unfolds. Cheers and keep those fingers crossed till then - wish me luck!
