Unpredictable Gear Shifting and Grinding Noise in 2021 Renault Arkana

Hey there, sounds like you're having a bit of a frustrating time. I had a similar problem with my 2018 Renault Megane recently, almost identical symptoms to yours, even down to the odd gear selection display. Turns out it was a faulty wiring harness - the latest in an illustrious line of fun surprises, ha! I know how apprehensive you may feel about mechanics after your last disaster visit. When I took my car to the garage, they had to dismantle some components, locate the faulty wiring and replace the harness. It was a reasonably time-consuming job, but they got it sorted in the end. The mechanic reassured me that although it might sound serious, a faulty wiring harness is a fairly common issue that they deal with regularly. So don't stress too much. Given your description, I would say it's worth getting it checked out by a trusted professional soon. It wasn't an enjoyable experience, but at least my gear shifting is smooth again and those grating noises have stopped. Hope this helps, and you get your Arkana running smoothly soon! Good luck!

Hey, thanks heaps for your insight! That's quite fascinating. Sounds like the 'wiring harness' ghost visited you too, huh? Honestly, I was hoping it might just be a minor issue, but I guess I better buckle up for the ride. Can you recall, by any chance, the cost for sorting out the wiring harness debacle in your Megane? Just trying to get a rough estimate before I walk into the mechanic's lair, you know? Also, did your car throw any other curveballs at you after the wiring harness got fixed? Your experience is super valuable for my situation. Cheers!

Hey there! Yeah, tell me about it - that dastardly 'wiring harness' specter sure did pay me a visit! Now, coming to your question, fixing that renegade wiring harness didn't exactly come cheap. If memory serves me right, it was around €1800. A bit of a pinch to the pocket for sure, but remember, a perfectly functioning car is priceless! And ah, did my car give me any more surprises once the harness ghost was banished, you ask? Well, initially, I was on edge, expecting the next disaster to strike any minute. However, things have been quite smooth since the mechanic waved his magic wrench. The gear selection display glitch that had been bothering me was also fixed after seeing the mechanic. So it's all good news from my end since then. So, brace yourself for a bit of pocket damage, but trust me, it's worth it. Here's hoping your car bumps smoothly down the road, just like mine. All the best!

Hey, I appreciate you sharing your experience. It sounds like you've had quite the adventure with your Megane. €1800, huh? Stings a bit, but you're right—having a car that doesn't sound like it's about to rebel against me is indeed priceless. Your story does put me at ease about the other potential problems, though. I'm now armed with a bit more insight than before, so the mechanic's lair doesn't seem as intimidating. Also, your good news after the fix is reassuring! Here's to hoping my Arkana will join the smooth ride club soon. Thanks for your advice and well wishes. Much appreciated!
