ENGINE
In January, At 65k miles I took my car in for an oil change. I informed them I was putting a quart of oil every month for the last 3 months just to keep the oil light off on my dash. Tech told me all Hyundais are burning oil and to just drive it until the engine blows and I’ll get a free engine replacement through Hyundai. The following month in February, I went to get my back brakes done. Mechanic told me I had no oil left in my car. They filled it up for me. In March, I took my car back to the dealership service center and demanded service. I was told I needed to do a combustion cleaning which would cost $700 and my extended warranty would not cover it because it’s considered general maintenance. I threw a fit and they agreed to do an oil consumption test. A few days ago I hit the 1k miles I was supposed to drive and took my car in for the first check. It was almost 2 quarts low and they said the next step in Hyundais flow chart is the combustion cleaning. They told me 1. It doesn’t actually clean anything and 2. Hyundai says this is the fix to the issue but it doesn’t actually fix anything. They said after, we would do another oil consumption test and then we could submit to Hyundai under “good faith” and ask for an engine replacement. I started researching and see this is a major issue with Hyundais and leave people with a blown engine and Hyundai refuses to cover anything. I traded it in today and got a new car, not a Hyundai!

ENGINE, UNKNOWN OR OTHER
After intermittent starting and car dying for no reason, the engine completely died while driving on highway. I filed a claim with Hyundai as part of Theta Engine settlement. I had the engine replaced at my expense, they will not cover. It is now burning oil at an alarming rate. This is dangerous and has happened to many many HYUNDAI/KIA owners as part of this engine problem.

ENGINE
Engine is consuming lots of oil. There are recalls on Sonatas but mine is not included, although I have a 2017 Hyundai Sonata Sport with a 2.4L Theta Engine produced in Alabama which are engines that are having defects with oil consumption. 2-3 months I was trying to get car into a dealership for inspection of engine because I kept having to add oil. They would not provide a loaner & I could not afford a rental at time or go without a car. In October 2022, I had to I take car to Hyundai in Trenton, NJ because engine light came on & car was jumping. Spark plug in cylinder 4 blew from low oil. On report from dealership that's exactly what is written on it. They replaced spark plug & got approval to start oil consumption testing. Had to drive 1,000 miles. Returned car & was missing 3 quarts of oil. Had to drive another 1,000 miles, 3 quarts of oil missing again. They performed top engine cleaning saying that could help eliminate the problem. I drove 1,000 miles after cleaning & was still missing 3 quarts of oil. In January 2023, dealership told me they'd put request through for a new engine. I called 1 month later giving plenty of time to have a response. They didn't put request through. Said I need to do more testing & had to leave my car there for a few days with no loaner provided. Why didn't they tell me this 1 month prior & why has no one called me to inform me of this. I can not afford a rental, miss work & my child miss school. We missed a ton since dealing with this issue & I've put out over $1,000 on rentals, oil, damages, deductibles, etc since this started. I contacted a Hyundai case manager & they are still going back & forth with dealership 2 months later. My car is obviously burning a lot of oil & after 3 tests & 6 months I should not have to go through this. In the last 1 1/2 months, I've had to replace spark plug in cylinder 1 twice & cylinder 4 once & constantly have to add oil. My cars shows ALL symptoms of the current issue with engines.

ENGINE, ENGINE AND ENGINE COOLING:ENGINE:OIL/LUBRICATION:SUMP/TANK
A hairline crack from the engine oil drain plug causing leaking oil. This is a very common issue for this engine. Mine was present when the car was new. My local dealer claimed my car has run over something, which never happened. No dent or damages on the oil pan, just crack on the side of pan. This is very common issue for this engine. Low engine oil level will cause engine failure.

ENGINE
Hyundai has an active recall and open service bulletins for an ongoing issue with Knock Sensors in 2017 Sonatas (my vehicle is a 2017 Hyundai Sonata Sport). Over the last 18 months... the vehicle has been in for service 6 times... 4 in the last 6 weeks... due to ongoing issues with the knock sensor causing the vehicle to go into "limp mode" and causing the vehicle to decrease speed to a max of 60mph. There is no pre-warning for when the sensor will trip and cause the issues... which means if a vehicle is on a highway traveling at a speed of 70mph or more, and the sensor trips... the vehicle will decrease speed down to 60mph maximum. The protocol I am aware of for the repairs... was a first step software update... 2nd step replacement of the sensor... 3rd step replacement of the engine. In 6 attempts to remedy the issue... Hyundai has refused to authorize the appropriate steps to complete the repairs and replace the engine, causing my vehicle to become a hazard on the highways without warning to myself as the driver, or other vehicles on the roadway. **Note, the most recent occurrence of this was 4/22/23.**

ENGINE
On our way back home from a road trip, the Sonata lost horsepower and I was only able to drive at about 40 mph (on highway). Once we reached the next town, stopped at an AutoZone since the check engine light came on. Tested the issue and it looks like the car went into safe mode and there was an issue with engine oil consumption. Added more oil and continued our way home. We were stopping about every hour to "rest" the car for about 30 minutes and recheck oil levels. After the 30 minutes, we continued on our way home. Once we pulled up tp our home, the engine died. We were fortunate that it didn't happen on the road. We haven't been able to turn the car back on. It has been like this since July 2022. Sitting in our driveway. We have contacted the dealership where we purchased the car and they refuse to have the car towed to their location and they won't even look at our vehicle. Currently, our VIN is not coming up with the engine recall when I search it here but it looks like our vehicle is also affected by that recall. We did receive a notice previously.

FUEL/PROPULSION SYSTEM
When decelerating, the vehicle will have a hard down shift or it feels like it accelerates with your foot on the brake after a hard downshift. Once you have come to a complete stop and you accelerate into traffic, it bogs down and does not move forward. It is dangerous to merge into traffic on a city street or in the highway. Our mechanic and the dealer cannot find anything. It is not predictable but it is dangerous to drive.

I still owe 1,000 to Capital One because my insurance company didn’t fully payoff this loan. Please help: I lost allot of money had to come up with a down payment for a 2019 Hyundai Tucson. This vehicle has the same problem with it can be easily stolen. My information is Mary Chanberlain 6700 Veritas Way 1-B N Chesterfield 23234 804-2411844

ENGINE, UNKNOWN OR OTHER
I got this car less than a year ago and immediately had issues within the 2nd day of getting it. Called the dealership and they had me take it in to a mechanic who fixed the issues. Since then I have had issues with this car consuming so much oil it's beyond ridiculous. This past Saturday night the car was being driven and all of a sudden the acceleration has become an issue. The car acts as if it doesn't want to go and hesitates. The dealership I got the car from no longer is in business and the loans were sold to another company and I'm not sure why no one is doing anything about the many issues with hyundai cars and their dangerous engine issues. When you're in traffic on the road with your children in the car and cars coming at you with full on speeds (here in alabama 70plus mph on interstate) it's very scary. Hyundai and kia need to take responsibility for these engines people are forking over thousands of dollars for. I'm not even a yr in and having several issues. Oil consumptions and issues with acceleration which seems that it leads to dead engines all the way around. We need help and we need it now. Please assist us with these issues. Thanks
