r/sonata

My parents just purchased a 2019 Sonata SE, 2.4L I4 F DOHC 16V Theta II GDI engine, 57,125 miles on the odometer. I'm wondering what sort of general preventative maintenance you'd recommend, as well as what NOT to do. I've seen engine/injector cleaner recommended several places, but also not recommended. A lot of contradictory information. Just looking for some clarification.

Also, I've tried to update the multimedia system, following all the steps laid out on the Hyundai website, but it doesn't recognize the USB drive. I know it's probably not necessary, but I'd love to know if anyone has any ideas.

Thanks!

After two Sonatas and almost 100k miles combined, I'm out.

Started with a '21 that got totaled in a bad accident. Spent some time shopping around, ended up back in a '22. Honestly, a few months ago I was even considering a '26 — but then I stumbled onto a deal on a truck I couldn't pass up. So I sold the Sonata, paid off the truck, and now I'm officially a proud member of the paid-off-vehicle gang.

No car note. No regrets.

Here's the thing — both of mine treated me well. No major failures, no horror stories. I kept up with the small stuff: oil changes, fuel system cleaners, throttle body cleaning, all the boring maintenance people skip. And the cars just worked.

These cars get a bad rap sometimes, but in my experience, if you actually take care of them, they'll take care of you. Appreciate the ride, do the little things, and everything else falls into line.

To anyone still in the Sonata game — drive safe, stay on top of your maintenance, and enjoy the ride.

I'm out. ✌️

I have a 2026 Sonata Hybrid Blue, I want to add a 360 camera view is it possible to add it and have it viewable on the current screen in the car? Has anyone made this upgrade? Appreciate any advice!

I have a 2015 sonata se with 100,400 miles. Thinking about getting it done. How much did you pay?

Has anyone adjusted the drum brakes when the brake hold doesn't quite hold at a stop? They chatter, slip then grab.

So I just bought a 2026 sonata SEL hybrid. I've had it for a week. When I was looking at cars they didn't have any of the scls in stock but they gave me the blue hybrid and I took it for a 24-hour test drive. One of the reasons that I chose the car was because it was comfortable. The dealer told me that the only difference between the blue and SEL hybrids were some additional features. Because they had to bring the car in from out of state, I could not test drive my specific car before buying. I didn't think it would be an issue because as I said the suits in the blue seemed fine and I was told they were the same as the SEL.

So that brings me to today when I drove it off. The lot seats were fine. I was fairly comfortable other than trying to get it in the exact configuration that I wanted. Now. After driving it for a week I cannot get comfortable at all. The seats are hard. They press into my back and my tailbone and make my butt, back and hips hurt. I've tried every configuration forward, backwards, up down, moving the steering wheel moving the headrest lumbar no lumba. think a lot of the problem is that there's no way to get the front of the seat lower than the back of the seat and the lumbar support is too low. So it offers no support and if I do use it it presses into my tailbone.

Does anyone else have this issue with their sonata? Did it go away as the seats were broken in? And what suggestions do you guys have for making the seat more comfortable? I'm so disappointed the seat issue is so bad that it's making me hate my new car and I dread driving it.

I'm 5'10 with a pretty long torso and long legs if that helps any.

Hello everyone, I'm in the market to buy a Sonata Hybrid Limited. Is it better to buy last year's model 2025 or aim for a new one in 2026? Also, what is the out-the-door price that I should aim for?

Looks like my sonata has two dead cells. Obviously the dealer will charge easy to much to make fixing it any sense. Had anyone found an option to have the battery repaired that is worth it?

Anyone know what it could be?

It’s like most of the noise is coming from the passenger cabin side. Changed cabin filter and motor blower.

Does anyone know how to switch the tachometer display back to charge/eco/power please? I was driving the other day and it just randomly went away. I have been to the cluster settings many times on the setup screen, but no matter what I choose, I cannot get the original setting back from when I first purchased the vehicle.

If it helps any, the charge/eco/power cluster display went away when it popped up the notification that my service was due. The service has been completed, the car is at 7962 miles, and the service notification is reset. The original display still hasn’t come back. I appreciate any help with this!
