Have the dealer shop check your battery connections and battery condition--it seems like there's been more than a few battery issues with the 2019's, including mine. My battery needed to be replaced within the first year because it wouldn't hold a charge. Let us know what you find out. --Rob

 

I thought same first that it might be a battery issue, but how come it starts using blue link. If battery would be low/dead there would be no way it can start. But sure I will update you as I hear from dealer. I may need to go earlier than May as I am seeing this too frequently now.

 

Loose connections / loose ground will manifest itself with intermittent issues like you're experiencing, as well as a battery that isn't charging correctly. If I was a betting man, I'd say it needs a new battery. Does you're ISG (Intelligent Stop & Go) work correctly? If it doesn't, it's a bad battery for sure.

 

I doubt it it has to do with battery. Read the post few times and it's unclear.

When you press the start, car doesn't start. Is the start button on your key fob? You mentioned you changed key fob battery.

And then you said you use bluelink same time it starts then works after? Battery seems fine then in this case.

No the start button is not on key fob, I meant the start button on the car. Car does not have the key start but just push start button and for that key has to be inside the car, my doubt was that may be key fob has low battery so car is not able to sense it so I changed the battery to rule that out.

Yes, using Blue link it starts and if I kill the engine and use start button again it works fine for few days and than same issue.[/USER]

 

It is not the car battery, because it started via Bluelink. Not the fob battery because the battery was changed. Let the dealer take care of it. Your only concern is it doesn't happen at the dealer, intermittent issue is hard to fix.

 

Yes, that is my only worry that if it happens before I take my car to dealer it will not happen again for few days.

 

More like some issue with remote starter.

Bad "start" button

 

Got it fixed last week and working great so far. As per dealership it was bad starter. Thanks everyone!

 

A bad starter? How does it start with Blue link while push button won't start. Sounds like stealership full of it

Sounds like BS to me.

 

I bought new Santa Fe in 2019 and now it is been less than 2 yrs and I am having issues with car not starting randomly. When I press the start button I do hear a tick sound coming from engine section but not engine starting sound. I changed the fob battery, same result. As Hyundai gives 3 yr free blue link so I tried that and yooooo car started. So I know I have a alternative to start the car. After starting the car using blue link I do not face any issues even if I turn my car off, it starts fine with key fob but randomly shows same behavior every other week. So I use blue link for first time and than car is good for new few weeks. I have service due in May so I will bring this up but has one else seen this ?

I'm having the exact same problem with 2019 2.0L Sante Fe. It happens intermittently exactly as you have described. Still trying to figure what it is. Dealership found no codes and every time the car started at the dealership so they could she replicate the non-stating issue.

I also swapped the starter relay and the problem still occurs intermittently. I also changed the batteries on the key fob that didn't make any difference. Next I will try cleaning the electrical terminals underneath at the starter. I'm really baffled by this problem. Sometimes it will start no problem for a week and then it just happens where it won't start. Will let you know after I clean the starter terminals. Does anybody else have this issue or any ideas what else to check ? Thanks (Dec 11, 2023)

 

The brake pedal must be depressed so you can start the car..... could be the switch on the brake pedal is intermittent. This switch also activates the brake lights so you might be able to check that.

 

Thanks - Yes i know the brake pedal must be pressed in order to start the car. Good point, I will check the brake switch also. I will post back after checking that as well as my starter electrical terminals.
From what I"m reading on different posts is that it may be the starter that is causing the problem. It could also be the Park switch as well and thats harder to get at. Not sure how I will check that: may have to take part of floor console apart to get at it. I will keep you folks posted on my progress.

 

Thank for the excellent update on how you replaced the starter. Yes, please keep the forum updated to let us know if the random no-start issue happens again.

For my Sante Fe - every since I cleaned the main ground terminal connection from the battery negative terminal where it connects to the chassis, I have not had any no-start problems.
I doubt I fixed the problem, but so far my car has started ok for the last 2 weeks.
I will also keep the forum updated if my no-start issue happens again. If it does, I will continue to troubleshoot and then as a last resort replace the starter as you did.
It will be interesting to see if you solved the no-start problem by replacement of your Sante Fe starter.
Happy New Year to you and your family. (Dec 31, 2023).

I am reaching out to seek assistance with persistent starting issues that I have been experiencing with my 2020 Santa Fe Limited Non-Turbo, currently with an odometer reading of 39,000.

Despite all dashboard lights illuminating, I encounter difficulties starting the engine. The car cranks but fails to start, necessitating multiple attempts (sometimes 3, 5, or even 10 tries) before the engine eventually starts.

Additionally, after driving the car for a short period, sometimes restarting becomes challenging, requiring repeated attempts. On one occasion, the car failed to start entirely, and I had to use a jump starter, resulting in successful ignition. See the video.

As the original owner, I took the vehicle to Autozone for a comprehensive check, including the original battery, alternator, and starter. According to their assessment, these components appear to be in good health.

 

I watched your video. It seems your car is trying to crank but fails to do so completely. It seems like your battery may be the issue. It seems the battery cannot supply enough cranking amps to sufficiently engage the starter. Measure the battery voltage with a multi meter during the start process. If it drops below 11V DC then you have a battery issue. I know you said you had the battery tested but it may be causing the problem. Batteries typically last more than 4 years, but not always. You may need a new battery.
Its possible as well that your alternator is defective but you said that was tested so lets assume that is ok for now.
Also clean the ground connection where the negative terminal of the battery connects with a black wire to the car chassis (frame).
Procedure below:
1. Remove the negative black wire off the negative battery terminal.
2. Now remove the other end of the black wire where it connects to the car chassis. I think the bolt size is a 10mm, so you will need a 10mm socket or adjustable wrench.
3. Take some sand paper (180 grit or similar) and sand the area of the chassis where the connector was connected. Make sure you sand enough so you can see bare metal. The area to be sanded should be approx. 1/2 inch square. Wipe clean with cloth.
4. Now sand the bottom side of the connector that was connected to the chassis, wipe clean with cloth.
5. Reconnect the connector to the chassis and make sure they 10mm bolt is tighten sufficiently.
6. Reconnect the black wire to the negative terminal of the battery. Tighten sufficiently.
7. Put some grease over the connector at the chassis area that was sanded. This will prevent corrosion of the connector where the bare metal was sanded.
Let me know how you make out

 

It cranked, but failed to catch. It is fuel injected, as long as it cranks, the computer will take care of fuel and spark. My guess is fuel or fuel system issue, engine flooded (why???), ignition system. I don't think it is a battery or starter issue since it cranked mulitple times.

 

Yes very good point. It could very well be fuel or spark issue.
Watching the video, the crank sounds very weak. Did you see the dash lights flickering when he was cranking. Dash lights shouldn't flicker like that during starting, thats why I think the battery may be dying under load conditions during a start.
He should still do the battery check and clean the ground as I described. What I suggested is easy to do and once completed it will eliminate these two items from from the problem equation. Although if the battery voltage drops under 11 V DC then I would suggest to replace the battery.
Let's see what happens after he does these checks/procedure, then we can guide him to other things to check.

 

@mohsentabibian - I forgot to ask - did you take your Sante Fe to the dealer since it should still be under warranty ?

 

Yes, it is under warranty. However, scheduling an appointment for them to inspect the problem is taking a considerable amount of time. I currently have an appointment scheduled for January 19th.

 

Thank you for your assistance. I followed your instructions and cleaned the ground connection. Additionally, I swapped the starter and fuel pump relays with others to identify any potential faulty relays. Subsequently, I attempted to replicate the issue to monitor battery drops, but the car started successfully each time.

I would like to provide additional information. Today, the car initially started after several attempts. I drove it for 20 minutes, but when I tried to start it again after a 30-minute break, it cranked but didn't start. After multiple attempts, I sensed that the battery had drained. I used a jump starter, and the car started without any issues.

 

Ok its looking like it may be a weak battery issue. You can still measure the voltage when starting, so make sure you complete this check (do it regardless if it starts or not). You may need a second person to help measure the voltage while other person is starting the car.
If your battery voltage drops to under 11 V DC, I would suggest to change the battery. If you do buy a new battery make sure its the same type and equivalent cranking amps.
Before buying a new battery, you may want to put a battery charger on your existing battery overnight for a couple of nights. If after this the voltage drops below 11 VDC (during starting) then proceed to replace the battery.
Let us know how you make out.

 

Thank you for your guidance. I followed your instructions this morning, using a tripod to record videos. One of the clips focuses on measuring the battery load during startup, revealing a drop below 11V after a few attempts. The second video captures the battery load while utilizing a jump starter, confirming your observation that the battery is indeed weak.

Upon reflection, I am skeptical about the effectiveness of recharging the battery, as the issue persisted despite a lengthy drive (~9 hours) to Oklahoma from Tennessee and the subsequent return journey (18 hours of driving). Additionally, I want to highlight that the ISG system ceased functioning entirely within the first few days of acquiring the car.

 

Forgot to mention. The battery should be under warranty, so if it is detective make sure you get Hyundai to replace it. Therfore don't buy one. Hyundai will obviously do their checks as well. Make sure you tell them to check the battery underload (while starting). In the mean time, like I stated in the previous post, charge your battery for a few nights on a battery charger until you have your appointment with Hyundai. Let us know how you make out.

 

Ok it looks like your battery is going defective. I watched both your videos and when you boost the car starts immediately. I believed you may have solved your problem. A new battery is required.

Your alternator is ok since your battery voltage increased to 14.5 V DC after the car started.

Please provide update once battery is changed.

 

Thank you once again for your assistance; your instructions were incredibly helpful. Today, I plan to visit Sam's Club to purchase a Durrecell car battery AMG 94R. If you have any better recommendations, please feel free to let me know.

 

Ok, all the best and keep the post updated to let us know if the new battery solved your problem. Looks like it will.

 

Our 19 SF had intermittent starting problems. New starter fixed it.

 

Thanks for sharing. Another person also changed their Sante Fe starter just a few posts before this because he was also having intermittent starting issues.
He is going to report back on whether it solves his starting problem.
My Sante Fe also has intermittent starting issues, but since I cleaned my negative battery terminal connection where it connects to the chassis (frame), it has been starting ok (3 weeks since I've done this). You can read all about this in the previous posts.
Also, I would recommend to turn off the auto stop-start feature. Having this engaged maybe wearing out the starters prematurely. I always disengage mine after I start the car.

 

After replacing the car battery, I experienced no starting issues. Additionally, I can confirm that the Idle Stop and Go (ISG) feature is now operational. Initially, it only functioned for the first few weeks after purchasing the car.

 

I'm glad you solved your problem. I shut off my auto stop-start feature (ISG). I don't like it. Over time, having it engaged will most likely result in premature starter failure do to the amount of wear and tear from so many starts. Take care and all the best.
