Hi everyone! I hope everyone is staying safe and healthy!

I was wondering if someone here was able to offer some insight into this issue I have been experiencing on my 2018 Hyundai Elantra GT (note: this issue only occurs in colder weather)

So, I have been having issues with the vehicle not turning over on the first attempt and I will hear a clicking sound, and the radio & headlights will turn on, but nothing else. Sometimes on the 3rd, 4th, or 5th attempts, the vehicle will start, other times I have had the vehicle boosted, and that does the trick right away. As I have stated. this issue only occurs in colder temperatures.

I have had the battery and alternator checked - both are fine - and I have switched keys, thinking that may be the problem.

If anyone has any ideas as to what this problem may be, I greatly appreciate it!

Sounds like a battery issue. Sometimes a battery can give a false positive, especially after being boosted. I would test the battery when it’s cold and before jumping it. That way you have a base reading. The cold cranking amps needed to turn the starter might not be there anymore.

I bought a 2018 Hyundai Elantra GT hatchback with only 33,000 miles a few months ago. I have experience similar issues starting this car. The first time this happened it was on a hot day in August. After driving for 30 minutes on the highway I stopped for food, and the vehicle would not start again. All I heard was a single click when I turned the key to start. This sounded like a failing starter motor or solenoid. I kept on trying the key and the starter would not engage.

I called Hyundai roadside assistance, and they sent someone from AAA to jump start my car. He could not get the starter motor to engage with a battery pack. He tried hitting the starter while I turned the key, and that didn't work either. I was advised to call Hyundai roadside assistance again and request a tow. When the tow truck finally arrived, the driver tried everything the previous technician tried. Eventually after hammering on the starter for a few minutes he got it to start, but he said this should not be happening on a 2018 car and the manufacturer should pay for this repair.

The car has generally started okay since then, but the starter problem returns intermittently. Sometimes it's just a matter of turning the key on and off a few times, but other times the starter motor won't engage, even if you have someone bang on the starter while you turn the key. For example, the other day, after the temperature dropped into the 60s after several days in the 90s, the car would not start, even when banging on the starter. All it would do was make a single clicking noise when you turn the key to start. Today the temperature was higher (mid 80s) and the starter worked fine.

I've scheduled an appointment at the nearest dealer and am waiting for their diagnosis. Meanwhile I do not have reliable transportation and am annoyed this is happening on a car with this low mileage, warranty or no warranty. I would not recommend Hyundai.

Hello, I know this post is old but I just started having the same issue with my 2018 Elantra gt. From the research I have done it's due to a faulty brake sensor. It's annoying, but you can bypass the brake sensor by press the push button start once, then praying it again and holding it for 30 seconds. Make sure the drivers side door is closed. First time I was stranded was literally over 1500 miles away from home!

I've been having the exact same problem! Only in cold weather! My battery is fine, got a jumpstarter and the second it's connected to the battery it turns over no problem! Alternator is fine also!

I actually haven't been having the issue anymore since I swapped a fuse in the fuse box in the engine. If you pop that thing open there is a fuse for the brake sensor. There are a couple of those same fuses used for other things, I think it was a 40a fuse. I just found one that didn't seem as important, interior lights or something like that, and flip flopped it with this fuse. I was having the issue pretty much every day, but I haven't had this issue since and it's been very cold here. I even forgot that I did that. If you need to know exactly what I did, let me know and I can try to take a picture or at least describe it better if you can't figure it out.

That's awesome! I would appreciate a picture of you could. I'm not much of a mechanic but I'll try to figure it out lol. Thank you again for the response!

 

[Rickthestick25]

Here is the picture. I circled the two fuses that we flip flopped. They also provide a handy fuse puller that I drew and arrow next to. That was very helpful. I'm not a gearhead either. I was actually ready to sell this car when this happened to me. If this hadn't fixed it I was trading it in. I do

really like this Elantra overall. I hope this helps for your car!

 

[Rickthestick25]

Forgot to mention the fuse box is in the engine bay. Driver's side.

 

[Coles2cents]

Thanks again! I'm going to try this ASAP!

I agree if the Battery does not have enough cold cranking amps its like having a dead battery.

Hi pal I think this is my issue. Could you send me a picture of the two fuses you swapped? Or at least tell me where to find them in the fuse box?

Did you just switch the fuses in those locations? Also, how does this fix the issue, forgive me i am just trying to understand the solution.

Had the same issue. Replaced the battery still did not start. Had to tow to a dealership. They replaced the starter at no cost (it was two weeks until expiration of the 5-year/60k warranty on my 2018 Elantra GT).

Same issue. Love my GT. Named her Rosie. I hope something here helps. Does this seem common with just this model or others?
