Honda Pilot Engine Stalling & Warning Lights: Help Needed!

Hi there! I've got some experience with cars (let's say mid-level DIYer) and dealt with something very similar on my 2016 Honda CR-V. Those symptoms sound exactly like what I experienced, and it turned out to be a faulty ECU (Engine Control Unit). I took it to my regular workshop, and initially, they ran diagnostics to confirm the issue. The ECU was indeed malfunctioning and needed replacement. The whole thing, including parts and labor, cost me about 625 Euro. They had it fixed within a day, and it's been running perfectly since then. Before you proceed, Any specific error codes you're getting? Does it happen more when the engine is cold or warm? Have you noticed any fuel consumption changes? BTW, this has been a known issue with some Honda models from that generation, including the Pilot and CR-V. Getting it checked sooner rather than later is definitely worth it to prevent any potential damage to other components.

Thanks for sharing your experience! I'm having the exact same symptoms with my Pilot (155741 KM). Mine's been doing this for about two weeks now, and I've been hesitant to drive it much. The error codes I'm getting are P0300 and P0420. It definitely happens more when the engine is warm, usually after driving for about 15-20 minutes. And yes, I've noticed my fuel consumption has increased quite a bit lately, probably using about 20% more fuel than usual. I just had my regular service last month, and everything was fine then. This started happening pretty suddenly. Your repair cost sounds reasonable, I was worried it might be way more expensive. I'll get it checked out this week. Thanks for giving me a heads up about the potential ECU issue. Did you have to get the original Honda part, or did aftermarket work fine for you?

Hey again! Glad I could help earlier. Yeah, those error codes definitely align with what I experienced, I had the same P0300 code. My CR-V also started showing these issues suddenly, right after everything seemed fine at a regular check-up. Funny how these things always seem to happen right after services, right? About your question on parts, I actually went with the original Honda ECU. My mechanic strongly recommended it, and I didn't want to risk any compatibility issues. The aftermarket ones were about 200 Euro cheaper, but I figured it wasn't worth the gamble. The genuine part has been solid for the past 18 months with zero issues. Just a heads up, while they were replacing my ECU, they also found that the increased fuel consumption had slightly gunked up my fuel injectors. Might be worth asking them to check yours too while they're at it. My mechanic did a fuel system cleaning which helped get everything back to normal. Keep us posted on how it goes with your Pilot! These ECU issues can be tricky, but once fixed properly, they usually stay fixed. My CR-V's been running like a dream since the repair.

Thanks so much for all that detailed information! You've really helped me feel more confident about getting this fixed. It's good to know you went with the original Honda ECU, I think I'll do the same. Better safe than sorry, especially with something as important as the engine control unit. That's a great tip about the fuel injectors too. Makes sense that they might need attention given my increased fuel consumption. I'll definitely mention that to my mechanic when I take it in. I've already called and scheduled an appointment for tomorrow morning. They said they'll do a full diagnostic first, but I feel much better going in with some idea of what might be wrong. Really appreciate you sharing your experience, it's exactly what I was hoping to learn before heading to the shop. I'll update this thread once I get it sorted out! Thanks again for taking the time to help out a fellow Honda owner. It's such a relief to know this is a fixable issue and not something that's going to break the bank.
