Engine died on highway. Noc sensor code indicates is a known problem for this engine. 2.4 liter Hyundai sante fe sport. Before engine died was burning much oil even after oil changes and borught in for recalls to dealer 2 mo before. Excessive burning of ooil wa a know issue at that time July 2023. Now Hyundai dealer saying the issue is a customer issue due to carbon build up on a valve. High burnin rate of oil is responsible for the carbon build up on the valve causing the engine to fail. Not a cusotmer problem but a engine design issue.

The check engine light came on. The vehicle attempts to stall when changing gears after a stop or deceleration and the engine shutters at speeds 65mph or greater. I am afraid the vehicle will stall if a fast acceleration is required such as moving onto a highway. A diagnostic was performed to confirm the engine is causing the "Check Engine Light or Service Engine Soon Light."

- Norman, OK, USA

This is a certified preowned vehicle. I am the second owner. I do my own maintenance. Currently this engine/vehicle has 64553 miles, I noticed it starting to use oil around the high 40k mile mark. There are no oil leaks. I have to add oil multiple times between oil changes and I just read that some of these can lock up and completely stop. I suspect this would be caused by people not checking their oil regularly however I am concerned that is the oil consumption is bad enough that this can happen at any time while driving so I wanted to add my complaint to any other existing complaints.

HIGH OIL CONSUMPTION: To the documented tune of 40 quarts consumed April17 - December 15, 2023, encompassing 24,116 driven miles. Hyundai America and this dealer knows all about this issue and is stalling on the remedy because it requires total engine replacement. Presently I am experiencing a P1326 engine knock sensor fault and I'm told by my mechanic a prospective catalytic converter failure due to high oil consumption. Experiencing loss of power and NO acceleration merging onto highway.

Engine consuming excessive oil which puts it and me at risk of catastrophic engine failure or fire either of which could cause an accident, injury or death to myself; other passengers and individuals nearby. This issue has been going on since shortly after purchase and Hyundai says it is a maintenance item and not a warranty or recall. I first informed them in July of 2021. I have since found out this has been a known issue and there was a class action suit in Ca. And numerous complaints to NHSTA. I went thru a series of Oil consumption test performed by and at the Hyundai dealership I purchased at- it failed all tests.

- Paducah , KY, USA

I have been conducting regular maintenance on my vehicle, getting oil changes, on average around every 6,000 miles. I have had the car since August 2021 and have had no accidents and haven't missed an oil change. My car is a little over 100K miles and the oil light began to come on close to 90k miles. The car is also leaking oil and all the service agent could tell me is that the are burns oil at an accelerated rate. Even though the oil light was on, NONE of the service agents mentioned any issues with the oil and nothing was mentioned when I purchased the car. I still have yet to receive the report from my last oil change from 10/06/2023. Also, the ABS light came on after I got the car serviced for a recall for the brakes and potential electrical fire while the car is parked. Each time I checked for a recall, nothing was found, even though this car clearly has an issue with oil consumption, well the engine in general.

In May, my vehicle began having issues with acceleration and was choking when going uphill, or would start choking when slowing to turn or start moving after being stopped. The engine light came on and had code P1326. Dealership did a system update and it went away. The car broke down not long after, wouldn't start. Replaced battery as it wouldn't charge and was drained. Still didn't work. Towed it to dealership. After several days, they said it might be the crankshaft position sensor. A local mechanic replaced it, it did not fix it. Spark plugs were completely burnt up and covered in gas. Changed spark plugs and it seemed fixed, until it broke down last week. Has code P0420 now. Checked oil, it has absolutely no oil in it and it has only been about 3000 miles since my last oil change. It is due for an oil change, but should not be completely out of oil. Burning oil can clog cat converter, causing P0420 code. My vehicle has a theta engine, which was involved in a lawsuit and settlement, which I only learned about yesterday, and have missed the deadline to file a claim. The vehicle has lost acceleration and died while driving, posing a risk to myself and other drivers. Vehicle is unreliable and unsafe. Dealership failed to tell me anything about my spark plugs, and did not mention my vehicle having oil issues. Non-dealership mechanics have been the ones to bring the issues to my attention. Corporate Hyundai will also not help.

Bought a used 2018 Hyundai Santa Fe Sport in December of 2022, as a second owner from a third party car dealer. No extended warranty was purchased. The vehicle currently has 122,750 miles. At the second oil change service done at Valvoline they told us it was not showing it had oil at the dipstick. I have driven it 337 miles thus far and it is already showing at the low mark. There is a recent settled law suit regarding excessive oil consumption. Some articles regarding the law suit listed 2010-2012 and 2015-2021 Hyundai Santa Fe as being affected, but the settlement only lists 2010-2012, as such the VIN recall search brings nothing. This vehicle is excessively consuming oil and I suspect the engine will seize in the near future.
