2018 Needs new engine - 5400 miles

So i guess I have the lemon. got oil change at 5100 miles, and the dealer did a flash update on the ECM. got near work and the check engine light came on. Took it back to the dealer they said nothing wrong, the code didnt below to my year. next day same thing. Took to a different dealer, the said the rod bearings are faulty, and it will need a new engine. Hyundai it going to buy it back I think, which is the right thing to do. This is the same problem that plagues the 2011-2014 Sonatas and the Santa FE's. There is a recall on those, and some other years are to follow I believe. Disappointing for sure, but they are going to work it out with me. The car is great otherwise, and no complaints on the other features. If you have any issues with yours or any car you own, be sure to report it to the NHTSA (National Highway Traffic Safety Administration). It is easy, and available online. They will also notify you of recalls, or safety issues. Without doing that, regardless of how small the problem is, there is no checks and balances to protect the consumer. You could help yourself and others to get their vehicles repaired in the event of manufacturer related issues.

Great warranty! Purchased new, have just over 5,000 miles in a year. No problems thus far. Dislike that the doors will swing closed when not fully opened with the slightest breeze. This sucks when you are half way out and the door slams into your knees. Seems like the doors have to be in the fully opened position to prevent this and even this is not a 100% guarantee. Do not like the fact that you need to remove a guard with about 8 - 10 screws to change the oil and filter. If you keep it off then the pulleys and belts are subject to road spray and the like. Do not like the fact that the automatic transmission is sealed and you cannot check the fluid level. This is not just a Hyundai problem however. Dash display could be easier to navigate. Also the tire pressure monitor will not display unless the vehicle is in motion. I DO like the fact that each tire pressure is displayed on the screen however, you don't have to guess which tire is low like in some vehicles. Interior plastics seem a little cheap but all in all this is the second Sonata that I have owned and I traded in a Toyota Camry for this car. I like the Sonata much better! After driving for a year and a half, I get a notice to come in for an engine software update. This update is supposed to sense engine vibration and put the car in safe mode before you blow the engine, some Sonatas have had engine problems since 2011. There have been problems after this software update as people have had to have wiring harnesses changed out etc. I was going to wait until they got the wrinkles out of the software but I started having downshifting problems recently. The car would lurch forward when slowing to a stop from second to first gear as if someone had stepped hard on the brakes. This did not happen at every stop but enough to let you know that something was wrong and annoy you as well. Hyundai has a TSB technical service bulletin about the transmission problem but no recall. I brought the vehicle in and had both the engine and transmission software updates in June 2019 at 9,500 miles. All has been great since, no problems with the engine and the transmission shifts much smoother. I still like the car and hope nothing else happens.

Sonata vs camry & accord

Front seating &dash board feels spacious. Blind spot and rear camera standard on base model was the clincher.

I have had my 2018 Sonata Sport 2.0T for about 8 months now and have 14,500 miles on it. For the most part I LOVE this car. It’s fast, comfortable, spacious, and good on gas. I plan on keeping this car for a very long time so I hope the reliability holds up. With that being said, my car has been at the dealership for the past 3 weeks. It has made a “grinding” or “vibration” sound from the engine since about 2,000 miles. It doesn’t do it all the time but when it does, it bothers me. It only does it between 1500-2000 rpm under light acceleration or reving the engine in park. Every time I would take it in for an oil change it would not make the noise. But finally after 3 weeks the dealership finally got it to make the noise and they believe it is the turbo shields rubbing against each other. So if anyone else has this issue, have the dealership check that. Hopefully my car will be as good as new when I pick it up Friday. South Charlotte Hyundai has been amazing, from the buying experience to the service department. They have provided me a loaner car to drive while mine has been in the shop. Definitely give this car a test drive if your looking for a sporty sedan with power.
