Even The Kia Dealer Couldn't Fix It!

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.

[@EyeMWing]

We likely saw why in the service data - it has you check the electrical circuits, and the relay itself (as if it were a discrete component that can be replaced!) and if both of those check out, it sends you to the PCM. If you stick your probes right on those solder joints to test the relay itself, it's going to test fine, because you're bypassing the broken solder joint between the board and the relay. The instructions should have you testing the relay *from the fuse sockets and connectors* Dealers are often married to the official procedures, and the service data is mostly copied from the official procedures.

[@JohnRodriguesPhotographer]

I am not an HVAC technician. I am a retired IT operations supervisor. I have a pretty old air conditioner system attached to my house. It is old enough that the wiring is starting to get a little iffy in places. Cost me a couple hundred bucks anytime it breaks. Beats the hell out of 8 to 10,000 to replace it. Often when the technician comes out I have checked the basic external things not opening the central air unit out on the ground, and have noted sometimes that I wasn't getting 220 into the fan or the compressor. Different occasions. And the technicians come out and all they have to do is take the cover off and they'll find a broken wire or something and they just have to visually inspect sometimes I'll double check with an amp clamp. But I've had a few technicians over the years ask me if I had worked in HVAC. I just pay attention to when someone's working on my air conditioner, I like to watch and learn something. I've always been that way. I already told you what I retired from, I know how to put up drywall, work with cinder block, to be honest I hate that, do carpentry and basic electrical work around the house, I can also do plumbing. All my life will at least since I was 10 I've been cranking wrenches on anything from a lawn mower on up. I am just a naturally curious and attentive person when something's going wrong. I remember a long time ago obviously my dad was going to throw out a lawn mower because he couldn't get it to start. Now you have to understand my dad was my mentor for a lot of what I can do. I asked him if I could take apart the mower and see if I could fix it, he said go ahead it's your time to waste! I tore it down and I adjusted the gap on the coil and the flywheel. I also cleaned the contact breaker points and I checked the carburetor to make sure there was no water in the tank or anything in the bowl. Dad had already checked that but I checked it anyhow. You should have seen my dad come running out of the shed when I pulled the recall starter in the dang mower started right up. You can see a part of him was annoyed that he couldn't fix it or didn't, but he was also proud as hell that I did. The mower was 10 or 11 years old. Daddy got it in 66. So he had already bought a new one. It was fun to find out it was probably the gap on the coil and the flywheel.

[@For--nop]

As someone that does microsoldering repair I want you to know you're doing a great job at isolating the true issue and fixing things "the right way" with consideration to the customer and their needs. In this case I think you landed on the right solution but please have some confidence in your solder holding. If you could physically see a loose joint (i.e. you know you're hitting the problem area) reflowing the solder on that will hold for years and years if not the life of the vehicle. Your reflow was probably stronger than as the joints come from the factory!

[@SmogFighter]

I’m with you on the strength of the repaired board. The lead-free solder that is used today is brittle and easily damaged.

[@TassieLorenzo]

@@SmogFighter "The lead-free solder that is used today is brittle and easily damaged." Is adding some leaded solder (as was done here) a better idea than just reheating the factory solder? Lead-free solder seems to cause lots of problems in cars. 😐 While this part was pretty cheap, other parts can be very expensive and I'd probably trust a part repaired with leaded solder just as much or more than a brand new part (e.g., 8th gen Civic hatches have the same radio & climate display as CL9 Acura TSXes and repairing the display pin connections with leaded solder is virtually free compared to the $500 that Honda wants for a brand new display!).

[@user-jd5sj8jx7r]

Many military products forbid lead-free solder due to tin whisker issues and poor reliability. Reflow with rosin core leaded solder is an acceptable mitigation.

[@TassieLorenzo]

@@user-jd5sj8jx7r I wonder why automotive regulations in some markets demand lead-free solder at the expense of reduced durability. It seems kind of dumb. But I guess all these "recyclability" regulations are based on cars being used for 7 years or so and then being dismantled and recycled, not spending 35+ years in use like military equipment (or as some private car owners want their cars to last)?

[@FourSeasonsNorth4x4]

Which leads me to my thought…how do you know the new one from the same factory(possibly) may or may not have the same problem. I now refer to the silver solder problem GM trucks had in their guage clusters..many of those joints also failed after a few years rendering many of those clusters useless..also creating a whole repair business in rebuilding them as it happens. Rebuild was simply resoldering broken circuits. Hopefully the new one is built properly and soldered correctly.

[@chrishartley1210]

Remember also that the training programs teach them that the computer will pinpoint the fault. When it doesn't, they don't know where to look next.

"Throwing Parts" isn't just in your area. It's caused by young, poorly trained and inexperienced mechanics. I suppose if the wages were better people would stay with it long enough to learn how to do it right. But it isn't just a car mechanic problem. Most corporations have tweaked their system to where they can pay the actual workers as little as possible while paying the C-Suite stupid money for sitting at a desk. Do CEOs really need to make $60million a year to do the job? The company's output sucks but then they just pay to advertise more and get new unknowing customers.

I graduated from a vocational school in 86 automotive mechanics. After a year of light mechanical I ended up being a drivability technician which made me the electrical guy also. I went into another field but continued performing car repairs on the side and sometimes at work. Watching you troubleshoot this vehicle brought back memories. I still troubleshoot hard issues for friends of friend’s where multiple times or shops cannot find the issue. Depending upon what the problem is, sometimes I’ll go ahead and fix it or I just tell them what they need and show them how to do it themselves. I don’t charge unless it cost me and depends on who they are. Close friends only buy parts and if they are struggling with children and good people, I buy the parts and repair. You do a good job troubleshooting. One may take many different roads to get where they need to be so I never make unwelcome suggestions but do offer when solicited by those having trouble. I’ll be leaving for work and first thing is having to find an open neutral in a lighting circuit only affecting one fixture. I continued on replacing ballast and installing LED bulbs last night leaving that fixture out knowing what I needed to look for today. I do new installations of sometimes one of a kind equipment and add to other equipment which includes installation of breakers and relays in the control panels with running conduit and such. I returned to maintenance after working in management for 15 years up to being an area manager and plant manager. I went back to what I love with so much less stress and hours.

This video is the exact reason I've subscribed to you. I don't really do cars, I'm an old software geek. You approched the problem cold, no real clue what was happening and worked it. You tested everything needed from the 40A fuse to the relay board. You did that in turn and in sequence. Trace, test, note results, compare with the expected result. That is an ideal way to diagnose what was happening. Try a change, try the ignition. Rinse and repeat. I bow to your skills with the car's electrical circuits. I just hope I can do that same process with my software problems.

I just recently found your channel and I'm glad I did. Your process of logically tracing circuits and troubleshooting steps is refreshing to see. I never like just throwing parts at a problem and you have given this old wrench turner new inspiration on how to go about tackling complex issues on these newer models. Thanks and keep up the great work.

[@rogerb709]

Great job, Eric! If you want it to stay fixed after you replace the module, you should also replace the cover.

[@camjarman2641]

You hit the nail on the head when you saw "a ring of solder". This is known as a "dry joint". Seen this many times in electronic pcb's. Quick scrape, resolder with lots of flux, job done.

[@DishNetworkDealerNEO]

Dry solder joints tend to work at first, but as vibration and thermal expansion and contraction cycles happen, the circle widens and the joint becomes positionally intermittent, acting like a sore, loose tooth!

[@keithlibner9259]

Had an electronics shop in the 80s. You would not believe how many things I fixed by doing a good visual inspection. A magnifying glass and a bright light could often find minute cracks in solder or foil for a quick , easy and satisfying fix.

[@nicodenhaak3961]

As a experienced audio tech with also 35 years of expertise in consumertech, i was so happy to see you take this (right), approach. Step by step narrowing things down while some piece of gear is acting up, is the only reliable way to track down a problem with resonably certainty you are down to root cause. you have inspired me in the past, to go the extra mile in my own diagnostics, as i was a bit set in my ways. when you said: around this solder joint i found a crack, i knew you found the problem sir! But you where right to get the lady piece of mind, and buy a new module. great job, as always ☺ best regards from the Netherlands, Nico den Haak.

[@desertsoldier41]

Yeah you never know if the new part might be updated with better Soldering or a better design. Can't blame the tech if its a new part, if it is a Board repair then you might not be eliminating the problem that caused the Solder to crack in the first place.

[@davidconley6267]

Good job, believe you got it. 22 years as an aviation electronics technician and can't tell you how many times a cold solder joint has been the problem, especially for intermittent problems. Reflowing solder fixes many issues.

That is strange most dealers that run into a situation they cannot figure out they contact the manufacturer who then gets a specialist involved. If that does not work it heads up the chain of command. Nice to see Real Mechanics that diagnose a problem before replacing parts. Good Job!

You’re spot on. Eric is very smart, and I’m not trying to diminish what he does. With that said, theoretically someone who has the service info, wiring diagrams, and uses a methodical and logical approach could fix this. Eric has all of these to use, and puts them all to use very effective use.

[@MrStatic101]

I’ve done energy management system/electrical troubleshooting for commercial buildings for years, digging through control panels and tracing out miles of wires. This was such a treat to watch you truly diagnose those circuits. No guesswork. Also even when you probably fixed it you still ordered the part to error on the side of caution. You sir are a fantastic technician.

[@ag4allgood]

Yeah , Eric probably fixed the problem by reflowing the solder to the pcb platethru connection. I have worked in electronics for 50 years & 7 years on a solder joint that is constantly subjected to vibration will make a once good joint go BAD. To the eye it might even look perfectly fine too ! Thing is to have access to the circuit diagram of the car. Once you have that research on the code also leads to the area of question. This lady sure was pissed enough to put her hand thru that fuse box ! Problem is there are many of these solder joints in cars today. Having a good solder iron is a must today. Great job of showing how to do an electrical repair.

[@natehess7663]

Having to track wires thru a building and find out where the failure is! That is always challenging , every job is different and there often is not a wire diagram present. As a Hvac/Refrigeration Tech we often have to do it, it can b very time consuming but very rewarding when you find the problem.

Really enjoyed your method of finding the problem! You have a new subscriber here. You were smart to not disturb the components so that it would stay in a no start state for troubleshooting. Intermittent problems are the worst because if it is caught in the no problem state it is almost impossible to diagnose. Hard to fix something that is not broken.

This is how problem diagnostics are meant to be done. Methodical, step by step, with proof for why something is causing a problem. Great Job!

[@mph5896]

Intermittents can be really tough to find. Eric O got it dead broken. Much easier to find an issue when its completely broke.

[@86753091974]

The market dynamics have created this. Customers think that all you have to do is plug a magic tool into "the computer" and it tells you what's wrong and how to fix it. Unfortunately spending time to get to the actual problem pays very very little.

[@ianide2480]

Error codes, scans, probing voltages, and advice did me no good on my last diagnosis. I was told that my car did not have a fuel pump relay by an "expert." The exact statement was something like, "don't worry about relays, these don't use relays anymore, it has a module that controls the fuel pressure." It uses a PMW controlled control circuit to regulate the speed/pressure of the fuel pump, this module was located in the trunk and through the back seat. I used my oscilloscope to probe the output of the module to the fuel pump and the wire going back to the computer, tested the voltages and did everything I could to determine the point of failure. The error code was a missing acknowledgement from the module itself and low fuel pressure on both banks, plus random misfires. I haven't kept up well with technology in cars but I followed a plan that was as methodical as I could. To top it all off, this did not happen all the time and I couldn't easily reproduce the issue, the car would just suddenly die while going down the road. I tested every wire at the fuel pump control module and it all looked good WHEN I tested, every damn time. I do not have access to service data, being just a schmuck in his driveway, but it did occur to me to look at the service manual that came with the car. I read through the diagrams for the fuse blocks and saw (to my surprise) a fuel pump relay. At that moment it did occur to me that, of course it makes sense to use a relay to feed power to the fuel pump control module. I popped the hood and saw that the AC relay was exactly the same, swapped them, and went for a drive. After a while the AC stopped working but the car kept going just fine. Problem solved. Of course, I did mildly load the parts cannon. I purchased a a fuel pump control module for $75 (seemed cheap at the time) and a new fuel pump for like $150 (also wasn't to bad of a price). I am actually glad I got a new fuel pump, I was fixing someone else's work and the old fuel lines at the fuel pump were "fixed" with zip ties and duct tape (so I didn't feel to bad about fixing that up properly). All told, a $7.00 part would have got me going again with very little frustration. I'm not sure why the "expert" ford mechanic told me that they don't use relays on these? Moral of this story, do not assume and look at the simple shit first, which is what I usually do and I don't know why I bothered listening to anyone. (this is one of the many reasons why I have trust issues when it comes to mechanics) sure the pump isn't "controlled" by the relay, but it sure is powered by one. Unfortunately I have far to many bad stories when it comes to paying for my cars to get fixed, so I just muddle through it the best that I can.

[@86753091974]

@@ianide2480 glad you fixed it but this illustrates my point. If you were a professional tech working on this car you would have billed an hour to do 2 3 4 days of work. Most techs are paid by the job. The economics of that don't make sense. Would you be willing to be paid an hour to do an unknowing amount of work that may take your entire week (intermittents are extremely common). 95% of the general public thinks that your problem could have been solved by a tech plugging a scan tool into the car and therfore are unwilling to pay for "daignostics". What's the answer? I don't know but it will get more and more expensive to fix these types of problems as techs are leaving the industry in droves.

An Air Base I was stationed had an auto repair shop operated by a Tech Sargent. An airman reassigned from Germany had a Opal auto with him This was the early 1960s. It quit running and got towed to the shop. The diagnosis was carb problem...The car owner was told getting parts would be several months from Germany. The Sargent rebuilt the carb using American parts and when the piece from Germany arrived he put it on. The car ran better with the jury-rigged carb so the ordered part went back. That shop probably got a lot of young airmen interested in Mechanics as an occupation using a GI loan.

[@JohnRodriguesPhotographer]

He often comments his videos are basic and nothing exciting. In reality he doesn't just show us how to fix something. He shows the world how to properly diagnose and troubleshoot, not just the physical task but the mental breakdown of what he is doing. Troubleshooting in my old since retired field, IT, was incredibly important. I remember a time when the mainframe kept crashing as soon as we brought it up after the last crash. I personally wrote the procedure to document a system crash. And I was following that procedure when the vice president came storming in and screaming at me. It was about that time that I found the problem. We essentially had a hard drive with an error on it. Either a head touch or something happened but the drive was no longer good. And that's when I pointed to it walked away from him and made a phone call to our engineers who were at lunch to tell them we were down and needed them ASAP. I also told him exactly what the problem was. They came in looked at what I had circled on the printout, walked over to the cabinet and swapped out the drive. While they were doing that I was getting ready to reload the system. Troubleshooting is such a lost skill. And by that I mean most people that go through the tech schools and get certified for computers in general aren't taught how to troubleshoot. Basically it breaks you call Mama. I remember the first time I watch this video the first thing I noticed was I didn't hear anything turning on when he turned the key. One of the things I can normally hear on his videos is the relays clicking and sometimes I can hear the fuel pump too. It's kind of surprising given the noise level I worked in for 30 years. I didn't hear any realize clicking or fuel pumps running nothing.

When you said you saw a circle around one of the relay connections, I knew you were onto it. That is the little visual clue that the solder/connection is cracked. I've seen them turn a dark black circle from arcing high voltage in monitors, to slight discoloration on a resistor or diode in a logic circuit. You DID find something satisfying.

[@FrackingCanuck]

Yup. Just watched this vid yesterday and had to pop by for the comment on cold solder. As a guy with a good amount of electronic repair experience, including in-car PCBs, I was first, impressed with the proper & decent quality soldering iron station, and that the proper gauge of solder was chosen for the reflow /repair work on a PCB. If not obvious visually, a good examination under magnification will often show up the culprit. When Eric said he spotted a ring around one of the terminals, that's a classic visual of cold solder, as all electronic techs would know. Great diagnostic technique and a perfect demonstration of a colder solder issue by applying pressure to a connection. With a reflow of all suspect connections, I also would have had no problem putting the repair out the door with a warranty.
