Seeking Advice for High-Voltage System Issue in '01 Nissan RNessa Electric Vehicle

Hey. Had a similiar issue with my '04 Nissan X-Trail (also electric), about 95k km on clock last year. It was starting to feel like a turtle rather than a road runner, if ya get what I mean. Turned out, there was a defect in the individual parts of its high-voltage system just like your RNessa. First up, a diagnostic showed that there was a problem in the inverter converter and the power control module (PCM). They were not chatting with each other properly, causing that sluggish start and power loss you mentioned. Plus, the battery resistance was higher than normal which messed up with the whole electrical shebang - headlights, indicators, the lot. Once these issues were detected, my mechanic replaced the malfunctioning inverter converter and did a reset on the PCM. For the battery, they ended up doing a quick voltage drop test, and from there, dropped in a new 12-volt battery for good measure maybe. Just wanted to say that replacing these components really resolved the issue for me, made a night and day difference. It was quite a serious issue though, could've led to a complete breakdown if not addressed timely. The car runs as smooth as a whistle now. Feeling chuffed! So yeah, give these things a check. And remember, go to a trained mechanic who knows his onions about EVs. Best of luck!

Hey there! Thanks for sharing your experience with us, it really put things into perspective. Your saga with the X-Trail and the miscommunications within the HV-System sounds pretty close to what's happening to my RNessa. Just a quick query, do you remember what kind of price tag the mechanic slapped you with for all these repairs? I'm trying to get a ballpark figure so I won't be taken aback. And since all the changes, has any other issue come up with your car, or has it been smooth sailing all the way? Cheers!

Hey again, Nah, it's no biggie, always glad to share my experiences and make the way a bit easier for my fellow car enthusiasts. Now on to your queries. The best part was that the repair didn't cost me a penny more than 0€! Yeah you read it right, not a single extra Euro for fixing the individual part defects in the high-voltage system. Since it was all under warranty, it just needed a well-trained mechanic to identify and rectify the issue. As for your second question, ever since that visit to the mechanic, well, it's been a dream run . That cranky error in the high-voltage system? Completely vanished. Feels like my good old X-Trail came back from a fabulous rejuvenating spa treatment, all bright-eyed and bushy-tailed, if you catch my drift. So don't stress too much, find a good mechanic who knows their stuff, and your RNessa should be up and running in no time. Cheers!

Lovely, thanks for following up. Your responses were really insightful and I'm feeling way better about taking my old RNessa into the shop now. It's fantastic to hear that your X-Trail's doing great post-fix. I'm hoping for the same result. And dang! 0€ then, ‘ey? That's a steal and a half. Let's hope I can strike some luck and the warranty covers mine too. If not, well... let's not go there now, shall we? Anyway, cheers. I really appreciate you sharing. I'll give your strategy a shot and keep my fingers crossed for a smooth outcome. Here's to hoping the mechanic I find knows their electric systems as well as yours did. Stay tuned, will share how it goes!
