Eclipse Cross Hybrid: Water Pump Crisis & Cooling Woes

Hey there! I actually faced something really similar with my 2020 Mitsubishi Outlander PHEV last summer. The symptoms you're describing match what I experienced, constant coolant loss, overheating, and those annoying warning lights. Took it to a certified Mitsubishi dealer and turns out the auxiliary water pump had a faulty control cable. The pump itself was fine, but the cable that controls it was shot. The coolant was leaking because the pump wasn't circulating properly. They had to replace the cable and do a thorough system flush. It was a serious issue that needed immediate attention, you definitely don't want to risk damaging the hybrid system. In my case, the car was driveable but I didn't push it. The repair took about a day and a half because they had to order the cable. My advice? Don't wait on this one. Find a certified Mitsubishi dealer or a hybrid-certified shop. The cable issue is pretty common in these models, and they'll know exactly what to look for. Hope this helps with your decision. Let us know how it goes.

Thanks so much for sharing your experience! This is exactly the kind of info I needed. Ended up getting it fixed at a Mitsubishi dealer last week, and the symptoms matched what you described perfectly. Just wondering, do you remember roughly how much you paid for the repair? Also, has everything been running smoothly since then? I'm a bit paranoid about potential future issues now

Hey again! Glad you got it sorted out! Yeah, I remember the costs well because I actually just got it fixed a while back, it was 225€ for the cable replacement and labor. The mechanic found that the control cable to the pump was definitely the culprit, which was causing that "Additional water pump limited function" warning. And to answer your question about how it's been running, absolutely perfect since the repair! Not a single issue with overheating or coolant loss. The warning lights are all gone, and the car runs like new. I was pretty worried at first too, but it's been completely reliable since the fix. I've put quite a few kilometers on it since then without any problems. These hybrids are actually pretty solid once you get these little quirks sorted out. Just keep up with regular maintenance and you should be good to go! Let me know if anything else comes up, always happy to help out a fellow Mitsubishi owner!

Thanks that's really reassuring! My repair bill was actually pretty close to yours, around 240 € all in. Just wanted to share a funny story about getting it fixed. When I finally took it to the dealer, I was so nervous about getting ripped off that I practically interrogated the poor mechanic! But he was super patient and even showed me the old cable, it was completely shot. While waiting in the lobby, I met another Eclipse Cross owner who had the exact same issue. We ended up chatting for ages about our cars! The best part? On my drive home, I could immediately feel the difference. No more scary temperature gauge climbing up, and the engine's purring like a kitten now. After sweating bullets about potential hybrid system damage, it's such a relief to have it sorted. Thanks again for all your help! Really appreciate you taking the time to share your experience. Definitely helped calm my nerves about the whole situation. Take care!
