Clicking on startup, turned into knock?

Thank you so much. I copied your post so that I can make sure to have access to it. Sounds like by the sound of the suggestion about good oil and filter you did hear the clip. Thank you so much. I have been so worried and without the car for about a month now. I have to try to drive tomorrow to work and need it to last a little longer. I appreciate your advice!

I found the oil you recommended- they do sell high mileage as well as I have seen oil additive recommendations prior to now, should I stay w 6 of 5/30 because it’s warm most of the year where I am or go w the 5qt and leave I Qt room for an oil additive like moly or something?
Hyundai has the filter- I’ll go pick up if it’s not too much, she didn’t have a price on the phone. Thanks so much.

Thank you, now I have learned so much, I won’t forget in the future.
So, I found the filter and ring for only 10 dollars at Hyundai /Kia - and with the purchased oil found a great jiffy lube avail to do the change for $41.00 using my products.
I should have recorded the techs reaction after pulling my car into the bay, he comes into the lobby all concerned asking “ how long has it been sounding like that.
He told me normally he couldn’t accept the liability to change the oil and was surprised I made it there. He was willing to give it a try once he was assured, I was aware of how bad the engine was- he didn’t try to sell anything extra, even though I could have used wipers, because he said I’d be lucky if the car didn’t shut off leaving.
He did show me the clogged air filter and said that “may” help so I changed it for $29.95 as well since I was trying what I could.
He said it took 4 quarts so I have some oil left over- when the previous mechanic opened the oil cover, he noted the container didn’t look oily enough, and sometimes a plugged filter or bad pump can be why, but he didn’t find that.

This Jiffy guy noted something when I ask about oil additives, about possible oil leak around a valve, but I can’t be sure he said that IS a finding or if it’s happening.

The Jiffy guy did say however an oil change wasn’t going to help the sound my car was making (I have a video/audio clip in original post) that he’d be willing to do it, and also said who knows, maybe after I circulate the oil into the engine, but maybe he was being nice, not sure.

I know it’s going to be near the end, but it’s just not possible without being able to work at least a few more months, and being so desperate because all things hinge on the ability to finance life, you will try very hard to have some hope and be willing to reach and not give up when it’s maybe past the point of hope.

It’s because also hard to accept complete engine failure so suddenly, got in to leave work and it sounded the way it now does, and next day, July 4th is when it kept dying each time I tried to slow down too fast, like at a red light, I’ve not been able to find the problem since, and lost 6 weeks work, spending several hundred in taxi/Uber during that time, while it was with the mechanic that really couldn’t diagnose or repair either, so I’m trying to be as wise as I can, here out, and your advice has been straightforward and intuitive as well and education I’ll keep going forward.
From here out, I’m going to learn all I can engine wise, just so I’m not so lost if/when I need to act quickly and make major repairs.
Thanks, you so much, anything Else you can think of I’ll be more than happy to check into!

Think my previous reply is missing, let me re-add a vid clip again now.

Think my previous reply is missing - let me re-add a vid clip again now

For whatever reason the video upload is glitchy. It took a long time to render, and I noticed the video clip was super short, so I made a whole other reply with the full-size video upload. I feel like it failed altogether, since the compressed too so long and only resulted in 1.5 second of 30 second clip, let me try one more time to use the feature that has you “take a photo or video” rather than select from file, maybe that will auto fit it the video file to upload better. One moment.

Re-uploaded.

So, I first noticed what did sound more like what I guessed MAY be a timing chain clicking /ticking right after having brake work done this spring- during the brake install the shop had ask me if I wanted to replace the “no 3 coil pack “ - I had noticed a serious lack of power at acceleration and loss of power uphill, w increased fuel usage- and due to that and the increase of fuel cost, I had always used the least expensive fuel-
Back to the ticking sound, it only happened when I very first cranked the car, once it had ran a couple min, it disappeared altogether, so I really didn’t think there was an issue at all, and thought maybe the shop just left a part wrapper on something that was tapping onto a fan or something.
It wasn’t until the July 3 afternoon that I got in from work and the car sounded that rough and just wasn’t the clicking ticking but the knock you hear now - along with it stalled out the next day and didn’t want to start back really - that’s when I put it in the shop -
The shop didn’t really seem to know what to do with it, really they said to just find another car, butI was desperate for them to at the very least look into it- I had seen many other Hyundai vehicles that had serious knock and sound that were able to be resolved to some point - and I just wasn’t In a position to even begin to think about replacing engine or car yet-

I really don’t know what they did, but when I got there to pick the car up - about 3.5 weeks later, the battery was dead completely- to the point it never could rebuild - so I was left to have to replace it just to try to see if I could salvage the engine at all-
Since I replaced the battery last week, the car has at least not ever stalled again, it has not had an issue restarting - I’m not sure what happened to that battery but the car came back worse off than it went in the shop if that’s possible- I don’t know, it’s discouraging to have lost so much time but I was at their mercy, and hopeful.

Since the new battery, I had a brief time that there were NO dash lights, no engine light or anything- I am not sure when or why the air bag light came on- or what that’s about -
Since I drove the car Friday, I had to take it to work and home, the engine light came on - that was a 20 min trip each way, and I wasn’t happy about doing it- but an Uber/Lyft /taxi is about 50.00 -nearly the amount I’d make at work myself

Trying to think of what else, so when I had been brainstorming on what to try, I did add Lucas oil treatment- this was prior to getting it to the shop -

The fuel I put In today I did buy premium but I’ll be honest, I prob would not budget for that on an ongoing basis-

I did add a fuel additive this spring once - don’t think that’s any issue ( or help )

One thing with the stall I had wondered is if the steering /ignition had an issue, bc I can sometimes remove the keys but the car registers the keys are in the ignition bc it won’t allow me to lock doors and the key in chime is ringing- I usually reinsert key, Turn to right, back off and remove key again and I’m good to go- but even if I have an issue there - doubt that goes to the engine -

I had thought it may be crank shaft position - and /or a sensor - there were 5 things I listed after combing the internet- that may explain the sound, and still be possibly fixable -

There may be more relative info I can give you- but these are the things recent and most relative I can think of -

I have considered that the engine could have been tampered with, but seems more likely that the age and mileage would explain issue, it was just so sudden and I would have thought some warning would have lead up- since I have to be so careful with taking care of it - I don’t even like drivers to get too close to me on the road -

Thank you for your attention, I really do appreciate this more than you could imagine and I will send a clip of the engine as soon as the thunder eases off

I did bring in the owners manual so I can quickly refer to, or look up an paticular s-
That recall info was interesting, as I had noted reading the stalling issue other owners had- I have had this off and on as well-
Once thought was loose battery, but it happens when the engine isn’t doing well- and it most likely happens as you are slowing down, decelerating, or haven’t warmed up well and go into gear too rapidly, if and when it occurs, so for me, 9 times out of 10 was at a highway red light - so a sudden slow from 65 to 75 mph to stop - but it’s not been an ongoing issue, so that two years ago, I thought I fixed it when I installed new battery and connections -
It’s happened two or three times last year when I noticed it losing power and getting horrible fuel economy - and the light came on that related back to emissions and I wondered if I had a converter problem ( or tampering bc we have had many converters stolen for the metal I the area )
But then the notorious stall presented again on July 4, recently, the morning after I noticed it sounded so bad when I got in to leave work- but this July 4 was really hot, and true to form I was on a major highway, w 75 mph sp limit and not many red lights so the one I came to, you go from full speed to sudden slow it it catches you - and I stalled, this time it didn’t want to start back, didn’t want to jump off w the power pack 600 I keep in the vehicle - and had to be jumped by a passenger that helped, but took quite some time -

That night coming home, the same light caught me and I stalled, no one out so I had to rely on my power pack to jump start but it took 10 minutes and I practically ran each stop sign near home just to make sure I didn’t stall, and turning into my parking lot, at home, it stalled and would not restart -

Now, since I have added the Lucus, have had it looked at, and since had to add a whole new battery, there hasn’t been a single stall yet - and the way it’s running is smoother and more stable- even if the noise is still there, for example, your question as to does it get better when warm, I feel it gets more stable, for example, leaving the auto repair that couldn’t diagnose it, I had to rev up the engine at each red light to keep going, I had to ride the brake and gas at same time to try to keep from stalling, and sometimes before the new battery last week, it just would stall, at a stop sign-
Now I have driven it all the way to work, to pick up my daughter after work, stop for pet food, and home with no stall- we have been able to take for the oil change and pick up the oil filter at dealership and home - no stall, and it’s stable at a red light, I don’t need to actively work at keeping the engine running at each red light, stop sign or turn, it’s going to stay running without me in the driver seat if need be and it’s not running hot, smoking, nor oil light coming on - and sometimes even at idle it feel very smooth and normal, if it wasn’t for the audible clunk clunk, you would not feel the issue- it’s smooth feeling and not jerky, so yes, I def feel like it smooths out after it’s warmed up -

Ps on the oil amount - I checked it from cold and rechecked after running awhile and it was just over the Fmark- feels like most of the oil from the 5qt container was used - out of the 5 qt and 1qt I gave them at jiffy, so the most likely nearly used the full 5 quarts but I will keep an eye on it - IF it’s short, I will have the option to add an oil additive - IF that’s even anything to help- I know I had read good things on Moly but didn’t find it to use when I used Lucas
