My truck started making very funny noises out of the engine area, two nights ago, and the next day, the noise persisted, and the car stalled. When we checked the oil, it was bone dry. There was no oil light warning. This car is very well-maintained.

Engine is consuming at least 1quart of oil every 750-1000 miles with no oil leaks.

My engine is burning about 3-4 quarts of oil between oil changes.

- King George, VA, USA

Engine is consuming 1 quart of oil every 1000 miles. I add 1/2 quart every 500 miles in order to be safe. If this vehicle is driven by someone other than a person like me who checks the oil level between oil changes the engine would fail due to lack of oil. The dealer wants $150 to conduct an oil consumption test! several dealers tell me that this condition is ok, really?

Consuming 5 quarts of oil in less than 1000 miles, stalling. Not starting

- Lawrenceville, GA, USA

Oil consumption is SUPER high. Not even 1 month after oil change have to add 2 quarts of oil. Have replaced gaskets in the engine but the head gaskets are also needing replaced when car not even that old. No oil leaking to be seen from engine. Oil consumption causing failures of other parts costing more in repairs.

Oil and filter was changed the 1st or 2nd week of March. (Mobil 1 full syn. 5W-20, with a Hyundai filter) A. Oil black, which was typical for the car (approx 1 qt low, topped off multiple times in the approx. 5000 mi since the last oil filter change) Note: On 12/21/22 Rowe Hyundai of Westbrook, ME, performed the ABS Recall, and we had the 2nd Carbon BG fuel injection flush performed. They noted oil was low and appeared dirty. Oil topped off that same day. I also asked the service manager why the engine burned/ leaked so much oil, and was suggested to try the Hyundai oil filter, in which I bought two. Because of the continued leakage of oil around the oil drain cover plate, I asked for a new oil plug washer and was told there was one taped to each one of the oil filter boxes. The first Hyundai filter and washer was installed the first of March 2023. All prior oil / filter changes the oil plug was never loose. I, [XXX] dad, [XXX] have been changing my oil and filters on all my cars for the last 10+ years (not to include when I was younger) est. >60 changes, and never have I had a loose oil plug. new Hyundai filter and drain plug washer were used. Installation was performed to manufacturer-??s spec. B. 5/13/23 added 24 oz. of Mobil 1 full syn. (had approx. 1000 miles since above oil change, this was the typical oil burn) C. 5/17/23 [XXX] left for Baltimore, and 2 hrs into trip (on rt. 15 Merrit Pkwy) noticed the red oil light come on, stopped the car and shut the engine off. Called tow truck, found Hyundai dealer with a good reputation. Police stopped and pushed her to a safer location. Car towed to Balice Hyundai of Fairfield.

April 17th 2023 my cars decelerate, wouldn't accelerate above 60 mph and would randomly decelerate as low as 15mph. The check engine lightvwas constantly flashing and the rmp wouldn't go above 2. I called motorworld and Hyundai. Motorworld said I needed a knock sensor replacement. They replaced the knock sensor. I called Hyundai again to see if I could be reimbursed. They said no. Hyundai then told me that because I paid to replaced the knock sensor my engine was now covered for life. A I ri 14th 2023 the exact same thing happened to my car again. I had it towed to motorworld. A week later I was told that they recommended an $800 oil consumption test because they said the oil was very low. I told them that my oil light never came on. The car was failing. I told the that I just had an oil change and that I thought the prior mechanic cheated me out of oil because my oil light came on 2 weeks after getting an oil change. This whole week I've been going back and forth with Hyundai re: this problem with is noted on websites. I was told that there is nothing they can do. I asked them to replace the motor. This is an engine problem and the engine is covered under power transmission and because I paid to replace the knock sensor. However it is not the knock sensor. The car did what it was supposed to do if tge engine is in danger of failing. So why did the charge me $583 for the knock sensor replacement and now they want me to pay $800 for an oil consumption test. It's obvious that the vehicle is consumption oil. There are no oil leaks. I spoke with Hyundai again yesterday. I told her that Hyundai needs to replace the engine and I feel that they stalling and putting me in danger. If this happens again I'm in danger, especially on the highway. Motorworld called to confirm that I was told on several occasions that because I paid for a knock sensor my engine is under warranty for life. Motorworld tod her that it's not. This occurred in April and again 5/14/23

Car uses an excessive amount of oil. Have to add more than a quart every 1000 miles

- Salem, MA, USA

Driving my 2018 Hyundai Santa Fe Sport and began hearing occasional rattling noises in engine. Engine light came on - so I made an appointment to take car to API Repair Shop. Next day engine light began to blink and car stalled and started up only to stall again, before starting up. Drove home and parked car. Had it towed to API for diagnostic test. They determined there was a problem in the oil line. They dropped the oil pan to fine pieces of metal. They stopped working on the car immediately and looked up reports to find there was a Hyundai recall for engine problems. (same as described above only some engines caught fire). API had car towed to Jones Hyundai in Bel Air. Jones Hyundai refused to honor the warranty or fix the recall saying another repair shop 'tampered with the engine'. API says they only dropped the oil pan in an effort to diagnose the problem. API made me aware of the recall which I was never notified by Hyundai. API said it has to be a certified Hyundai dealer to fix recalls - which is why we towed it to the nearest dealer, yet Jones Hyundai in Bel Air is refusing to fix the problem. They said they will not touch the car. How can they refuse to fix a recall - under the law aren't they obligated to replace the defective part?

I have encountered 2 issues that can lead to engine failure: 1- Crack in the Oil Pan, 2- High oil consumption leading to engine failure. 1 - I took my vehicle in for the 5,000 mile oil change Jan 11, 2023. I also told them that my engine was idling rough when I was sitting still. After an hour wait, I was told the oil level was very low and the technician had found a crack in the oil pan near the oil drain plug. I was showed the crack in the pan and allowed to take pictures. They had a pan in stock and replaced the pan. My odometer reading for the service was 87,476. 2 - On March 25, 2023 I checked my oil level and the dip stick showed I was 2 quarts low. The odometer reading at that time was 90,826. I added 2 qts of oil. In retrospect my engine had starting idling rough about 2 weeks before I had to add the 2 qts of oil. The engine ran smoother after the oil was added. I have pictures of the odometer reading and the dip stick. I went into the dealership on March 27, 2023 and told service advisor about the problem. They couldn't get me in until Mon. April 3, 2023. Odometer was reading 91,146. The 90,000 mile service was done and I was told my engine was consuming a lot of oil. I am now in the process of getting Hyundai to approve an Oil Usage Test. If it fails, the dealership told me Hyundai would replace the engine.

The acceleration of the vehicle from a stop. Whether from a stop sign, stop light, even sometimes after slowing down after a turn. It hesitates while the gas pedal is still being applied. Causing the vehicle to slow and other vehicles are forced to brake. The engine does not rev and the tachometer does not move. There are no warnings lights or vehicle notifications. After several attempts to bring it to the dealership, they are never able to replicate the issue. The OBD scans show no issues. It has never been a constant problem, however it remains as a "hit or miss" issue. Could be days of no problems and then popping back up every stop.
