Warning Lights Haunt Eclipse, Airbag System Alert

Hey! I had a similar situation with my 2007 Mitsubishi Lancer (also gasoline). Got both warning lights at around 90k km. Turned out it was indeed the acceleration sensor that was acting up, it's part of the active hood system. Took it to a certified Mitsubishi dealer last month because this system is pretty complex. They ran diagnostics and found the sensor was defective. Had to replace the entire sensor unit since these parts aren't serviceable separately. The repair wasn't super complicated but it needed special diagnostic equipment to reset the system properly. Not exactly a serious issue for driving, but it's safety-related so you shouldn't ignore it. The active hood system is there to protect pedestrians in case of an accident, so it's worth getting fixed right. My repair took about half a day at the shop. If I were you, I'd go straight to a Mitsubishi specialist or dealer for this one. Regular mechanics often don't have the right diagnostic tools for these specific systems.

Thanks for sharing your experience! That's really helpful to know it was the acceleration sensor. I've been having the exact same symptoms. Do you remember roughly how much you ended up paying for the whole repair? Also, has everything been working fine since they fixed it?

Hey again! I'm happy to give you an update! Since getting it fixed at the Mitsubishi dealer, everything's been working perfectly, no more warning lights on my dash at all. The Active Hood malfunction is completely sorted out, which gives me peace of mind about the safety system working properly. As for the cost, it came to exactly 315€ for the whole job, that included the new acceleration sensor, labor, and resetting the system with their diagnostic equipment. While it wasn't cheap, I'd say it was worth every penny for the professional fix and knowing it was done right. I'm actually glad I went with the dealer for this one, they knew exactly what they were doing with these specialized systems. Given you're having the same symptoms as I did, it sounds like you're dealing with the identical issue. Hope this helps with your decision making! Let me know if you need any other info about my experience with the repair.

Thanks so much for all the details! I actually went ahead and took your advice, brought it to the local Mitsubishi dealer yesterday. You were spot on! It was the acceleration sensor causing both warning lights. Funny enough, my repair cost was pretty close to yours, paid 330€. The whole thing took about 4 hours, and the service was way better than my previous mechanic. The technician even showed me the old sensor and explained what went wrong. Since the fix, my dashboard's completely clear, no more warning lights! Really glad I asked here first and followed your suggestion about going to the dealer. Saved me from wasting time with regular mechanics who might not have had the right tools. Thanks again for helping me make the right call on this one! One less car worry to deal with now.
