Come along as I have a look at a 2015 Kia Sorento that has been at the dealers countless times and another local shop to see why the heck this thing won't start! It cranks over just fine but won't start.... sometimes. The other shop towed it to me to see if we could make heads or tails of it. Let's have a look.

    Your common sense process of troubleshooting is the only way to go.. the baffling thing to me is…are there really that many service pro’s out there without common sense? Anyways, absolutely brilliant diagnostic work as always!

  2. Avataaar/Circle Created with python_avatars Richard Jones says:

    Eric, that is what I call evidence working, find the evidence, or even perhaps a hint of evidence and follow that exact trail. It might take thought, and above all process, (neither of which are always over evident everywhere) and the magic happens. Only it is not magic, it is doing things the right way.

  3. Avataaar/Circle Created with python_avatars Duncan Evenson says:

    There is a TSB on that exact fault and repair with Hyundai

  4. Avataaar/Circle Created with python_avatars Zippy TheChicken says:

    most likely was the main relay… its a very common problem… however didn't you say there was a fixed main power connector which you jumped to test it but that main power connector could be bad and pushing down on it makes the connection … good luck

    About muffins, just take both……Cheers from Comox Valley..😃

  6. Avataaar/Circle Created with python_avatars k. roy says:

    very good!

  7. Avataaar/Circle Created with python_avatars Mark Bren says:

    I'm surprised the kia dealership couldn't figure this one out. Way to go Eric!

  8. Avataaar/Circle Created with python_avatars c cole says:

    nice job . a very common problem on pc boards today especially on vehicles

  9. Avataaar/Circle Created with python_avatars Stacy Dornan says:

    Your one smart cookie Mr O

  10. Avataaar/Circle Created with python_avatars Mel Meter says:

    Another great fix!

  11. Avataaar/Circle Created with python_avatars Alan Nilsson says:

    You have just proven that dealership has no one in their shop that bothers to try and diagnose problems or trouble shoot in any way. It is a rare find when a mechanic will try to figure out what is going on when the fuse box is HIT and then the car STARTS…they seem to only care that 'hey, now the car started…so just give it a punch in the fuse box when it won't start for you' and send you on your way. Well done, SMA!!

  12. Avataaar/Circle Created with python_avatars Wayne Morfett says:

    Awesome fix common sense great knowledge and not ripping of the customer that’s a win win as far as I am concerned stay healthy take care

  13. Avataaar/Circle Created with python_avatars Awesomus Maximus says:

    Dealerships they are all dodgy except Maybe Lexus

  14. Avataaar/Circle Created with python_avatars Luis Puga says:

    Well that's your problem…..she's got to get rid of them Batman seat covers. Spotted them right at the beginning.

  15. Avataaar/Circle Created with python_avatars DirectCurrent says:

    One of the best diagnostic videos I have seen. And your logic about going about it is spot on. You are definitely one of the best one-man mechanic shops I've ever seen. Keep up the great work and continue to keep sharing these amazing videos with us. Wish you and the family all the best!👍

  16. Avataaar/Circle Created with python_avatars athhud says:

    No joke, I cheered in my head when you said that you were going to reflow the solder joints! I am so proud of you for not letting the soldering iron scare you away this time. Lol

    I have a feeling that in the times of “everything is back-ordered” you might get more into board repair than you like.

  17. Avataaar/Circle Created with python_avatars Alex Brown says:

    Brilliant job, mate. Your diagnostic skills are a pleasure to behold and your patience is extraordinary 🙂

  18. Avataaar/Circle Created with python_avatars noel castle says:

    Another great diagnosis well explained and methodical enjoyable to watch and learn . Makes you wonder why the dealership didn't just replace that fuse/ relay module or at least swap one to test though I suppose it started working and they shipped it and didn't want to put any time into a proper diag. Dealerships seem to he time limited in the diag department. That's a fairly new vehicle I bet good old Whimpies wouldn't have one of those sitting in their yard , $78 seems very cheap but here in Australia we pay big $$$ for our geniune parts due to shipping , lower volumes and our dollar is much weaker than the mighty greenback. Thanks again for the time you put into these high quality videos hope you get paid correctly for your time doing these it cannot be easy time wise owning and running a busy shop , being a husband father and not getting burned out mentally by it all.

  23. Avataaar/Circle Created with python_avatars Paul westerhaus says:

    you should remove the old solder then solder it back

  24. Avataaar/Circle Created with python_avatars Big Bear Venom says:

    Did you order her a new fuse block cover that she put her fist through ?

  25. Avataaar/Circle Created with python_avatars Mr. Lee says:

    Great one, Thanks Doc.

  26. Avataaar/Circle Created with python_avatars J.P. Simen☆ says:

    I'm the Greatest in the World! The problem is, it ain't Got No gas innit. Sling Blade style.

  27. Avataaar/Circle Created with python_avatars Brandon Cartwright says:

    Serious question about can high and low. Lets say i use an add a fuse in a fuse box for switch power on a head light circuit for fog lights. The reason is irrelevant but if that power wire was ran next to can bus wires or looped around can bus comm wires, could it interfere with the can signal. Amp power wires can cause feed back in rca leads, so could the can signal be sensitive enough to pick up outside noise if the wires are not shielded enough?

  28. Avataaar/Circle Created with python_avatars Inspired Mechanics says:

    Diagnostics 101… Work the problem. And you have proven this truly works if committed to it each time. Awesome job and video as always 👍

  29. Avataaar/Circle Created with python_avatars Zacharyt54 says:

    Mrs. O sticking it to the man! Don't mess with that, lady!

  30. Avataaar/Circle Created with python_avatars Kent Diego says:

    I repair a lot of old electronics. Re-flowing the solder at pins is often needed. For intermittent problems is is the first thing to do. It is a good solid repair that will last many years.

  31. Avataaar/Circle Created with python_avatars Slingbart says:

    did you order a new fuze box top? or put some water proof tape over it.
    I believe it was the connectors underneath shorted and as you pushed it, it made contact. similar to a power supply connector to a MB.
    Still another well made entertaining video and content, better than CBS, NBC or FOX

  32. Avataaar/Circle Created with python_avatars Marc Grobe says:

    Good job Eric! You stumbled across KIA Engineers field testing their new Anti-theft Device.

  33. Avataaar/Circle Created with python_avatars don box says:

    A systematic approach is a right way to go Eric. Good Work!!!

  34. Avataaar/Circle Created with python_avatars rorannerusan says:

    Great job Eric. I know the new leadless solders suck and don’t always last long. The joints break easy from vibration and heat. Maybe some one will fix them cheap someday using good solder.

  35. Avataaar/Circle Created with python_avatars Infinite Velocity says:

    I'd ship it. Just need a duct tape job over the cover to prevent water from intruding…

  36. Avataaar/Circle Created with python_avatars Brett Millett says:

    I’m a software engineer. How you proceeded with the diagnosis is pretty much how I tackle a software bug. You’d make a good engineer. Heck, auto-mechanics these days should just call themselves engineers. Well, at least the ones who can do this like you can. 👍

  37. Avataaar/Circle Created with python_avatars Sandmansa says:

    That's interesting to know. The local Kia dealer near me wants to sell you the whole dang fuse box for an insane amount of money. So, instead. I just went to a local U-pull it yard and grabbed a pocket full of them. Seems to be a fairly common issue with Kia Sorento's.

  38. Avataaar/Circle Created with python_avatars Jeff Kottwitz says:

    Absolutely love your videos Eric

  39. Avataaar/Circle Created with python_avatars Jeff Kottwitz says:

    I definitely agree it is always super frustrating when it starts and you can't figure out why…

  40. Avataaar/Circle Created with python_avatars will d says:

    Ivan just lost his shit after this one

  41. Avataaar/Circle Created with python_avatars Marc miIIs says:

    I would of just wired a wackamole hammer to the air intake and sent it. jk

  42. Avataaar/Circle Created with python_avatars Marshallz79 says:

    Hey Eric, shoulda said put your fist through that like and subscribe buttons lol 👍

  43. Avataaar/Circle Created with python_avatars David Pruitt says:

    As an engineer and someone that used to do IT help, I can appreciate looking stuff up. 90% of my "solutions" involve googling and reading the answer on stackoverflow. I would rather have a mechanic that's willing to spend a few minutes reading instead of hours randomly poking around.

  44. Avataaar/Circle Created with python_avatars BigOwlBrain says:

    By the time you had cut to the kitchen, I had suspected that a relay was likely going to be the issue based on the size of the hole in that fuse box cover. I did not expect it to be on a circuit board and as a separate block inside the fuse box.

    It makes little sense to have to mold additional plastic bits and manufacture a board which cost extra to produce rather than design the overall fuse box the correct way. Even if needing circuit isolation it would have been doable. If in a pinch and needing to get it running quick if it was a bad relay, it would have also been nice to be given the option to swap around relays just to get it running.

    Once can certainly say though that it wasn't designed to force you to bring it to the Kia dealer to fix it, because apparently they can't !
