Dying Outlander Battery? Expert Solutions Inside

Hey there! I had a similar issue with my 2015 Mitsubishi ASX Diesel last winter. Started with the same symptoms, weak starts and flickering lights. Thought it was just the battery at first, but turned out to be more complex. Took it to the Mitsubishi dealership after my regular mechanic couldn't pinpoint the issue. The problem was actually a defective control unit that wasn't properly regulating power distribution. It was affecting the alternator's charging system, which in turn was draining the battery. Had it professionally diagnosed and fixed at the dealership, definitely a serious electrical issue that needed proper attention. The repair involved replacing both the control unit and alternator. Since then, everything's been running smoothly. No more starting issues or electrical problems. If you're experiencing these symptoms, I'd strongly recommend going to a certified Mitsubishi dealer. They have the right diagnostic tools and expertise for these specific electrical issues. Stay away from general mechanics for this one, electrical problems in these models need specialist attention.

Hey, thanks for sharing your experience! That sounds exactly like what I'm dealing with. I'm really considering taking mine to the dealership now after hearing your story. Just wondering, do you remember roughly how much the whole repair set you back? And has everything been working fine since then, or have you noticed any other electrical quirks pop up? Trying to get an idea of what I might be in for. Thanks!

Hey again! Just wanted to follow up, yeah, I got it fixed at the dealership and it cost me 600€ for the control unit replacement. Best money I've spent on the car, honestly! Since getting it sorted, the battery's been holding charge perfectly, no more of that frustrating self-discharge issue that was driving me nuts. It's been running like a dream for months now, no flickering lights, no weak starts, nothing. It's like having a new car! And the best part? Not a single electrical problem since the repair. I know 600€ might sound steep, but considering how much trouble these electrical gremlins can cause, it was totally worth it. Trust me, going to the dealership was the right call. Those guys know their stuff when it comes to these specific electrical issues. Save yourself the headache of trying cheaper options, I learned that lesson the hard way! Hope this helps with your decision making. Let me know if you need any other info!

Just wanted to update everyone! Finally got my Outlander sorted, and wow, what a relief! Took your advice and went straight to the dealership. You were spot on about the control unit problem. Mine ended up costing a bit more, around 750€, because they had to replace some wiring too, but honestly, it was money well spent. The whole experience was way better than my previous mechanic visits. They ran proper diagnostics, showed me exactly what was wrong, and fixed it all in one go. The car's running like new now, starts up instantly, no more flickering lights, and all the electrical stuff is working perfectly. Thanks again for pointing me in the right direction! For anyone else dealing with similar issues in their Outlander, definitely skip the general mechanics and head straight to the dealership. Sure, it might cost a bit more upfront, but you'll save yourself a lot of headaches in the long run. Really appreciate everyone's help on this one!
