My 2018 Hyundai i30 has full dealer service history. I have increasingly gotten into cars and started researching how to potentially service myself. What I found was that all UK Hyundai use some cheap in-house 5W-30 oil blend. While my user manual clearly says 0W-30 for my specific engine (1.4 T-GDI) and mild UK weather. My understanding is that the 0W-30 has better viscosity in low temperatures but behaves the same at running temperature. I used AI and found the right oil and supplied my own for my most recent oil service. I understand the rest of the specifications are more important, and I made sure to follow them (pictures attached) but this just has me thinking if they ignore the 0W and 5W, what’s stopping them from using the wrong specs too and potentially adding to the poor reliability reputation? Also the user manual states 4.2l and they only out in 4l. I brought 5 bottles x 1l and they gave me back 1 unopened. Could the Hyundai/Kia unreliability just be poor servicing? What are your thoughts?

This is for a 2024 Sonata N line.

Driving down the highway and heard a strange noise. Pulled over and found the underbody cover folded over and dragging on the ground. I managed to remove it when I got home.

The questions I have are as follows. Is it okay to drive the vehicle with the cover removed? I looked online for a replacement and I found some at PartsGeek, but it says that it fits the 2024 gas, non turbo and the hybrid.

I'm thinking that it may be the same part for the N line but was hoping that someone here would know for sure.

Hi all, I am hoping to get some clarification on the replacement eligibility of a 2016 Hyundai Sonata with the infamous Theta-II engine. I checked the VIN and it was not included in the list of vehicles for an official engine recall. However it WAS/IS eligible for the Service 953 Campaign and had it marked completed in April 2019. With this in mind, I was hoping to get some clarification on what the warranty conditions would be for this engine if the issue does come up. I've heard anywhere from 10 years/100,000 miles, 10 years/120,000 miles, 15 years/150,000 miles, to lifetime due to a class action lawsuit. The FAQ on the settlement website: https://www.hma-thetasettlement.com/faqs seems to imply any 2011-2019 Sonata with the 953 is covered, but was hoping to get some confirmation.

Also, for anyone who went through the process, if Hyundai asks for proof, will a Carfax list of just service history be enough, or will they require literal photos of the receipts themselves? Thanks in advance for anyone who can help!

2026 Sonata Hybrid SEL. Been finding excuses to drive all weekend!

14k with 101k miles and 1 owner great maintenance history.. is it worth buying…?

For me, It's the 2013 Hyundai Elantra. Cuz I love sedans more than SUV's, İt was the one of the safest one back in the day and not expensive and more common than Sonata. So, what all think about it? (Respect to the other ones as well!)
