Honda Elysion Nav System Failure: Causes & Solutions

Hey there! I had a similar issue with my 2016 Honda Pilot (gasoline). The navigation system died along with some erratic behavior from other electronics. Turned out the CAN BUS system had deteriorated wiring insulation, causing communication problems between modules. Had it fixed at a garage where they found damaged wiring harness near the driver's side footwell, pretty serious issue since it was affecting multiple systems. They had to replace sections of the wiring harness and recalibrate several modules. My mechanic mentioned corrosion was the culprit, damaging the twisted pair cables in the CAN BUS system. I'd suggest having someone check the wiring harness specifically, as these problems often start small but can affect more systems over time. Make sure whoever works on it has experience with automotive network diagnostics, not every shop is equipped to handle these issues properly. Hope this helps with your Elysion troubles.

Hey, thanks so much for sharing your experience! That's really helpful info about the CAN BUS wiring. I'm curious, do you remember roughly how much you ended up paying for the whole repair? Also, has everything been working smoothly since then, or have you noticed any other quirks with the electronics? My Elysion's been showing some similar symptoms to what you described, so I might be dealing with the same issue. Definitely gonna have someone look at those wiring harnesses now.

Hey again! Just wanted to update you on my repair costs since you asked, I paid exactly 235€ to get the CAN BUS wiring fixed. And I'm happy to report that everything's been working perfectly since the repair! The Message error between control devices completely disappeared after they fixed it, and all the electronic systems are now working like a charm. The mechanic did a great job diagnosing and fixing the issue. My navigation system is back to normal, and I haven't noticed any weird behavior from other electronics either. It was definitely worth getting it properly repaired by someone who knows their way around automotive networks. Since you mentioned your Elysion's showing similar symptoms, it really does sound like you might be dealing with the same kind of wiring issue. If you do get it checked out, make sure to mention these symptoms to the mechanic, it'll help them diagnose it faster. Let me know how it goes with your repair! Always happy to share experiences with fellow Honda owners.

Thanks for all the detailed info! Just wanted to give you guys a quick update, I took your advice and had my Elysion checked out by a new mechanic who specializes in electrical systems. You were spot on about the wiring! The repair ended up being a bit pricier than yours, cost me around 300€ because they had to replace a larger section of the wiring harness. But honestly, it was worth every penny. They found some pretty bad corrosion in there, just like you mentioned. The best part? Everything's working perfectly now! The navigation's back up and running, and all those weird electronic glitches are gone. The mechanic was super thorough and even showed me the damaged wiring, definitely learned my lesson about getting these things checked out sooner rather than later. Really appreciate everyone's help on this. Sometimes it just takes finding the right mechanic who actually knows what they're doing!
