r/HyundaiElantra

Hi, to start I drive a 2020 Hyundai Elantra with about 80,000 miles on it.

I was driving to my mom’s today and about 40 minutes into my 45 minute drive my car suddenly lost power out of nowhere. I turned a corner and it felt like the car had just switched off. My battery and oil lights came on as well as a couple others but I don’t remember what they were, I was too focused on pulling over and turning the car off. I turned it back on and everything restarted like normal and I finished my drive. I’m unable to take it to a shop today and have to drive 45 minutes back home but I’m worried about it happening again on my way. Does anyone have any idea as to what may have happened?

I will say that the state I live in is currently experiencing a heat advisory but there have been hotter days that haven’t affected it before. Just wanted to put that out there in case overheating could be a potential cause.

Once again, I am in existential pain with my 2017 Hyundai Elantra.

About a year ago, had several tubes leaking coolant, with that sweet syrupy smell having given away the issue. A thousand dollars or so later, all fine.

Had spark plugs and ignition coils go bad earlier this year, another grand, it is what it is.

But now, I got white smoke/fog coming out, ever so slightly, and I doubt it was condensation because there was a faint smell of oil coming out from the vents (my sense of smell isn't the best, I had to get close and sniff the vents to detect the oil smell).

So what's the likely issue here? Oil leak into my cooling system perhaps? Needing a whole new gasket or car??

I JUST finished paying off the last car repair was placed me in horrible debt, and was starting to have hope of starting my life again when this hit, lol

I purchased a 2024 Hyundai Elantra Hybrid Limited at the end of 2024. I got lucky and found a dealer loaner with 5k miles on it. When I first bought it, I looked into Bluelink and I swear the only info I found said it had a monthly fee, so I didn’t bother with it.

Fast forward to last week when I took my oldest to the dealer to trade her car in and found out that in my car it is included for free for the first owner for the life I own the vehicle!!

I was so excited, I set it all up, and everything was simple… until I got to the Digital Key. Mind you, I am a tech nerd, but it kept failing to connect. I searched Google, talked to AI… NOTHING WAS WORKING.

I had to return to the dealer to sign over the title on my daughter’s old car, so I asked for a salesman that was good with Bluelink to help me. Still nothing.

He told me to call Bluelink… y’all it took her minutes to figure out the issue. So I wanted to share in case anyone else has had this issue!

The whole process worked until I clicked “pair”. It wouldn’t recognize my phone. (I have an. iPhone 17 pro max) Apparently the issue is that in most newer phones, the NFC chip is in the very top of the phone. The instructions tell you to place your phone on the wireless charger to connect.. she told me to make it so the top of the phone touches the charging pad and BOOM. Connected.

So if you haven’t been able to get yours to connect, don’t lay it flat on the wireless charger, just the top of the phone needs to touch it.

I called the salesman back to let him know what the trick was, and he thanked me because a lot of people have had the same issue and he had no clue how to help them.

Hope this helps someone else who was ready to give up on the digital key!!! lol. Honestly having it wasn’t even a big deal, it just became a vendetta when I couldn’t figure it out. I don’t like when technology isn’t doing what it’s supposed to do 🤣

I own one of these with the 2.0 naturally aspirated engine and 6 speed automatic transmission. I keep hearing these are lemons due to main bearing failure, premature transmission failure, and piston ring failure. I'm currently at 68,000, no warranty. No issues other than minor oil consumption (1qt about every 2,000 miles) and some cosmetic stuff. Just how likely are the catastrophic issues? Like, percentage wise? I'm in a low crime rate area so I'm not as worried about Kia boys. Should I get rid of it or take the gamble?

I just bought a ELANTRA hybrid and one of the things I noticed when I hit the brakes sometimes there is jerky shifting that happens. It doesn’t do it all the time, but sometimes it’s extremely noticeable. Any idea if this is common? If so, is it something that the Hyundai dealership will fix?

When it is hot outside and I go up a hill on an interstate the Elantra suddenly slows down. Only happens when hot outside. Very dangerous when an 18 wheeler is behind me. Unable to go faster than 30 mph. Hybrid battery goes to only 5%. Brought to two different dealers and unable to find cause. Brought to an independent mechanic and he finds that the electric motor is over 260 degrees. There are NO codes captured for diagnostics!!!!! Anyone have this problem????

When I turn on the air conditioning, the engine temperature starts to rise, especially when the vehicle is stopped or idling. At the same time, the A/C stops blowing cold air and becomes warm. Once I start driving again, the engine temperature goes back to normal and the A/C becomes cold again.
The thermostat has already been replaced, but the problem is still happening.
