Hey, thanks for sharing your experience with us. I'm facing a very similar issue with my XTrail, and your information really came in handy. Can you recall roughly what you ended up paying for the main relay replacement? Also, have you come across any other problems with your Altima since the fix? Cheers!

Hey, glad to know my experience is helping! So, about the repair cost for the engine control unit's main relay, it was around 120€. Honestly, it wasn't too bad considering the fact that I was able to hit the road without any more worries. And to answer your second question, my Altima has been running smoothly since the check-up. The main relay issue was definitely the culprit causing my starting woes, and fixing it made a huge difference. Hope this info helps, and best of luck getting your XTrail sorted!

Huge thanks for sharing that information! Really helped calm my nerves a bit. Around €120 isn't a bad deal at all if it gets rid of this headache, and it's great to hear your Altima is still doing well after the fix. I'll get my XTrail into the shop ASAP and update here once I get things sorted. Cheers for the advice!

Hey there, I actually recently had a similar issue with my 2004 Nissan Altima. Noticed that it began to have starting issues and at first, I wasn't sure what was up. We figured at my usual garage that it was indeed the main relay of the Engine Control Unit (ECU) that was defective; exactly the same problem you seem to be describing. The symptoms normally entail difficulty in starting the engine, and in more serious situations, it won't start at all. Now, as for the fixes, it entails careful inspection and replacement of the faulty relay. Luckily, they had the necessary parts in stock, and the work was pretty straightforward for experienced mechanics. They managed to solve the issue efficiently despite it being a little intricate. I've got to say, this isn't a minor problem and definitely worth getting checked out as soon as you can. After my relay was replaced, my Nissan runs like a champion again, so I'd recommend you to get it into the shop soon. Good luck!
