The oil light would blink on, then go back offstarting abiut 7/15/22. We checked the oil, but it was fine. This happened for about 2wks, w/ the light never staying on or staying on & flashing. However, the oil consumption started increasing, needing more oil each time, but no indication of a leak. Then the check engine light started flashing & car went into limp mode w/engine knocking. This happened suddenly in traffic, which could have caused a wreck d/t sudden loss of power & inability to reach speed of surrounding vehicles. At this time, the oil light was not present, but 3qt of oil needed to be added in order to limp the car home. This was 7/39/22. Computer check gave code 1326. Engine failure seems immenent. Vehicle is available for inspection request. The issue has not been confirmed by dealer, but we have seen similar complaints on YouTube.

IT is burning oil and am very afraid to drive this car before it catches on fire....I am hoping the dealer will replace the engine or Hyundai Motor company to give us warranty without the hassle...

- Winthrop , MA, USA

It's knock sensor issue code was showing since 85000 mileage, dealer just got rid of the code and said can drive safely. Then again at 101000 mileage knock sensor code and Hyundai dealer said software is updated can drive safely. Also it's engine oil burning faster that we keep on topup oil all time. Then at after 108000 mileage my car started overheating, & it's engine seized. Now Hyundai don't want to fix such problems. I don't know maybe it get fixed, then catches fire on highway can cause death.

2017 Hyundai Sonata Sport engine is consuming oil at 85,000 miles and has done so since early 2022. I have had the vehicle to the dealer on numerous occasions regarding this issue; oil light coming on and immediately needing 3 quarts or more to fill it back up. The latest encounter was 7/17/2022 when the check engine light came on and when oil was checked, it was on the "L" level yet again and this was less than 800 miles since the complete oil change where 5 quarts of oil was inserted. This engine is known for oil consumption and at 85,000 miles it should not be doing it at this rate. Another consumption test is being requested.

Engine has 131,000 is driven less than 800 miles per month currently. And has excessive oil consumption. An averageof 2-1/2 to 3 qts of oil in a month. I first notice this problem, when I checked oil level about 3 months ago. Oil warning light never comes on letting you know it is low on oil.I contacted huyndai dealership and was told I need to pay for 6 oil changes. And an engine clean up to determine what problem is. It is clearly a factory defect that they are not willing to admit to. Customer should not be liable for a factory defect. Ive read Hyundai forums and founf many owners with same complaint but no action has been taken. Need help with this..

After travelling on the highway for approximately 1 hour the HEV light along with several other lights came on and the engine powered down. The instructions were to turn off the engine immediately. Luckily I was in the right lane and was able to get to the shoulder of the highway and turn off the engine. Tried several times to restart, but same message came up to turn off engine. Had it towed to closest Hyundai dealer for service. They couldn't look at it immediately, but according to them it started the next day and they drove it around (local driving) for 10 miles with no issues. I took the car back and after driving it again on the highway for 1 hour the same problem occurred and I had to have towed to my local Hyundai dealer. It has been in their shop for over 3 weeks and I still have no answers as to what may have caused the problem.

Driving on the highway at speed, the car decelerates to 30 mph and won't go any faster. This is the second time it happened. I took it to the dealership in September 2022, and it sat there for 6 weeks before they looked at it and said there wasn't anything wrong with it, and reset some fault. I took the vehicle back to the dealership on May 12, and there is no estimate of time for when it will be looked at again.

Had the car at the dealership one month ago for recall repairs. They said it was two quarts of oil low. First time that has been so low. Two days ago, driving home when I start hearing weird intermittent engine noise. Decide to drive to dealership. Almost made it when engine noise became very loud. Pulled over and had it towed to dealership. Engine failure. While waiting for tow, checked oil after it cooled - no oil on dipstick at all. No warning lights on dash. I shut engine off quickly after it was obviously about to fail, noise got louder. Most all maintenance done at dealership. 88k miles. 2017 Hyundai sonata hybrid. Dealership told me they have TWENTY cars with similiar problem on the lot right now
