I need some advice. I was driving my 2023 Hyundai Sonata on the interstate when, out of nowhere, it lost acceleration. I started hearing a loud knocking sound, and thankfully, there was a shoulder nearby where I could pull over. If I had been in the center lane, things could have been really bad.
I’ve only taken it to the dealer for oil changes, and I just filled up at an unbranded gas station today. I doubt the gas was the issue since it was 87 octane and many others were using the same station, plus I’ve filled up there before without any problems.
Now I’m hearing some kind of rod shaking, and there’s a strange smell like fluid leaking. The weird part is that my Bluelink app says everything is normal.
I’ve been stuck on the shoulder for seven hours waiting for a tow truck because they need an exact address, and there are no building numbers around here. I can’t even cross the lanes since everyone is flying by at over 80 mph. My car won’t start at all, and my cell phone is dying. To top it off, I’m hungry and thirsty!!!
I tried calling the dealer, but they were no help other than telling me to bring it in.
So, I’m really frustrated and confused…why would my 2023 Sonata break down like this at only 12,000 miles? I bought this car because the interior was amazing and it looks great too.
I had the same thing happen with my 2024 Sonata. A week after a service, the check engine light came on, and the dealer replaced two faulty fuel injectors. Then my car broke down on the highway, just like yours.
It turned out that a fuel injector seal wasn’t put back on properly, and the car was leaking fuel.
I got it fixed, and it’s been running fine for the last two months. My car has only done 5,000 miles so far.
No, that’s not possible because the diesel nozzle wouldn’t even fit in the tank. The same pump had two nozzles, and I definitely filled it with 87 octane.
I’ve also looked on Google, and I found that quite a few people have had breakdowns with this generation of Sonatas (2020 to 2023).
I feel like Hyundai has started neglecting quality control and being careful with the Sonata since it’s not as popular as the Camry or Accord. It seems like they might have cut corners somewhere. That’s just my guess.
Take it to the dealer and let the tow truck know you’re on the interstate. Give them directions like north, south, east, or west.
Also, since you only have 12,000 miles, when was the last time you had a service? A regular Sonata (not hybrid) usually needs an oil change and other maintenance every 6,000 miles. If you’ve been keeping up with the recommended oil changes, then definitely take it to the dealer to get it sorted out.
