Proudia Power Loss & Knocking Issues, Help Needed

Hey there, I had very similar issues with my 2016 Mitsubishi Outlander PHEV last year. The symptoms you're describing sound exactly like what I experienced, drop in power, rough acceleration, and increased fuel consumption. Turned out to be carbon deposits in the combustion chamber. Got it fixed at a certified Mitsubishi dealership after my regular mechanic couldn't properly diagnose it. They had to do a complete fuel induction service and clean the combustion chambers. It wasn't a quick fix, took them two days to complete the job properly. They also found that some spark plugs needed replacement. It was a serious issue that needed immediate attention because those deposits can cause long-term engine damage if left untreated. The hybrid system wasn't the problem, it was all about the combustion chamber maintenance. Since you've got a Proudia Hybrid, I'd strongly recommend going to a certified Mitsubishi dealer who specializes in hybrid systems. My engine's been running smoothly since the service, and fuel economy is back to normal.

Hey, thanks for sharing your experience! That's really helpful, sounds like you got yours sorted nicely. Would you mind telling me roughly how much the whole repair set you back? Also, has everything stayed running smoothly since then, or have you noticed any other quirks pop up? I'm trying to get a sense of what I might be looking at cost-wise and whether this fix tends to last.

Hey again! Happy to help! Yeah, I had to shell out 425€ for the complete fuel induction service and cleaning at the dealership. But honestly, it was worth every penny, especially since theyaged to fix that annoying cylinder knocking I was dealing with. The car's been running like a dream since I got it sorted six months ago. No more weird noises, power issues, or fuel economy problems. It feels just like when I first got it! Actually, I'm pretty relieved I didn't wait any longer to get it fixed, as the service guy mentioned that letting these issues drag on could've led to more expensive repairs down the line. If you're experiencing similar symptoms, I'd definitely recommend getting it checked out at a Mitsubishi dealer. Yeah, they might be a bit pricier than your local mechanic, but they really know their stuff when it comes to these hybrid systems. Plus, the peace of mind is totally worth it! Let me know if you need any other info, happy to share more about my experience!

Thanks a lot for all the details! I actually took your advice and got it checked at the certified Mitsubishi dealer last week. You were spot on, it was carbon buildup causing all the trouble. Cost me about 480€, a bit more than yours, but they also had to replace a sensor while they were at it. The whole experience was way better than I expected. They walked me through everything they were doing, and even showed me the gunked-up parts they cleaned out. Pretty eye-opening stuff! The car's running like new now, no more jerking or weird noises, and my fuel economy is back to normal. Really glad I asked here and got your recommendation. Saved me from potentially making things worse by going to a regular mechanic who might not have known their way around hybrid systems. Think I've found my new go-to service center! Thanks again for helping me dodge what could've been a much bigger headache down the road!
