Ignition Starter Switch Failure in a 2010 Kia Magentis: Seeking Advice and Experiences

Hey! Your issue sounds eerily similar to what I faced with my 2013 Kia Optima sometime ago. You're suspecting right! In my case, it indeed turned out to be the wiring harness - it was defective. Like yours, my ignition wouldn't fire up, really frustrating. At my garage, the mechanic had to test and trace the wiring harness to ascertain the root cause of the problem. They eventually found out the issue was with connectivity. They spent quite a good amount of time finding the exact spot of the defect though, as the wiring harness is a complex structure. Replacing the defective wiring harness was the ultimate solution, since fixing it wouldn't have guaranteed long term reliability. Isn't a big fuss as it sounds, just make sure the guys doing the job know their stuff. It wasn't really a trivial issue as you know, incorrect or broken wiring could potentially lead to serious damages. Hope it gets sorted for you soon! Drive safe.

Hey there! Cheers for sharing your experience, really sounds similar. So, it was the wiring harness for you, huh? A bit of a relief to hear I'm probably on the right track thinking it's the ignition starter. I'm curious, can you recall roughly how much that set you back? Knowing ball park figures always helps me to not get completely ripped off, you know. And since the fix, how's your Optima been? Any other pesky issues that came up? Thanks again. Stay safe on the roads!

Hey! That's correct, the issue was with the wiring harness. Once that knot was untangled, it was smooth cruising! To get specific with the expenses, fixing the wiring harness defect cost me around 95.00 €. A bit pricey, but worth it. As for your ignition starter switch suspicion, jackpot! That was sorted out when I took it to the mechanic. Since then, my Optima's been behaving - no more spooky surprises. Remember, it's all about finding a mechanic you can trust. Once you have that, these issues become much less of a headache. Safe travels! Let me know how it goes!

Hey! That's some great insight, really appreciate it. The cost doesn't seem as steep as I was anticipating. Relieved to hear your Optima’s in good shape now. I agree, a reliable mechanic is like a gold mine. I'm on a quest to find one in my area after the last shambles. You've given me a good place to start, and hopefully, my Magentis will soon be back to cruising smoothly. Thanks again. I'll surely keep you updated. Drive safe, cheers!
