Engine is consuming a quart of oil every 400 miles.

- Lexington, NC, USA

Unknown Vehicle made knocking noises and completely cut off on me. The vehicle had an oil change 1 month ago.

- Schererville, IN, USA

Car began to knock and lacked acceleration. I took it to a dealer and spent $300 on replacement of plugs and it seemed to be working fine. One month later on the highway, the car completely lost power and would no longer accelerate. I found online that the engine had been recalled and the warranty extended to 120K miles. Hyundai paid for a tow to the dealership. The dealership determined that the engine needed to be replaced and thought Hyundai would replace the engine due to the recall, but the replacement was denied by Hyundai. I do not not know at this point on what grounds, but the car has 117,000 miles on it and should be within the extended warranty period because of the recall. The estimate for replacement of the engine is $8000. I've only had the car a few months and expected to get at least a few years out of this vehicle.

Engine is buring oil. I drove about 1,400 miles since last oil change, and my engine had almost no oil. There are no leaks. My driveway is clean. My mechanic says engine is burning oil inside and he put "crazy" amount of oil to top it off today. He told me to change my oil every 3,000 miles instead of 5,000. He has been saying there is an issue with engine buring oil for some time and recommended contacting this agency and dealer.

Problem is the engine is burning two quarts of oil every 1,000 miles. Was taking car in for oil change and check engine light went on. Service person said car was way down on oil which is why engine light went on. Said there was a problem with Hyundai engines and to take it to dealer. Dealer Ettleson agent John Cunniff confirm that there is a problem with that engine and said they would run an oil test. Oil was changed with new filter and told to come back in 1,000 miles. Returned to dealer after 1,000 miles and engine was down two quarts of oil, dealer topped off oil and said someone would contact me. I called several days later and John Cunniff said that using two quarts of oil in 1,000 miles was within specs. He said to contact Hyundai customer service. I did with case # 19220125, and Frances was case worker. Attempted to contact Frances three times with negative results. I called and spoke with a Cindy who stated case notes stated Frances contacted Ettleson and they said two quarts of in 1,000 miles is normal, complaint was closed. Research disclosed there is a problem with oil consumption in that engine, backed up by their and other mechanics. I have 69,000 miles on the vehicle and a 100,000 mile warranty. I have all maintenance files for the vehicle since I purchased it. i have complied with the dealers instructions and have had my PCV replaced, and just keep adding oil to keep my engine running. Please advise my options.

my 2016 Sonata SE vin #[XXX] has a engine recall, Hyundai gave me a lifetime Warranty of the engine and power train. the Sonata has 84577 miles on the engine and is using 1 QT of oil per 1,000 miles. took the car to Bentley Hyundai in Huntsville, Al. for an oil change and to see what they will do about the oil issue. I'm to bring the car back to them in 1,000 miles for them to check out how much oil the car is using. I was told that even with the lifetime Warranty of the engine and power train that with the engine using a quart of oil that Hyundai won't do many thing to take care of the problem. If the engine was given a Lifetime warranty by Hyundai why won't they do any thing to correct the oil problem.

Car started bucking and slowing on freeway. Took car to dealership October 2021 after 2 weeks, I was informed the car needed a new engine. A few days later I was informed, my battery needed replacement. Three months later, January 31, 2022 while in the freeway, my car started bucking then decelerated from 70 mph to 10-20 mph on the freeway ( only reached 40 mph going down hill). Check HEV system and Check Hybrid system indicator triangles were on. Battery light indicator and engine light indicator also on. I had car towed to dealership. I was informed I needed two plugs replaced. 2 weeks later, the same problem happened again on February 19, 2022 I was informed, I needed two plugs replaced. The plugs were replaced. This time it wasn-??t two weeks before the same thing happened again. Warning lights displayed: check HEV system, check Hybrid System, battery and engine lights are on. Car doesn-??t accelerate over 15 mph. This vehicle has had several recalls, which I am told all recalls check out fine. No one can find a reason why the HEV, battery and engine lights are on. In the meantime, I-??ve purchased a battery, spark plugs, rented a car, spent almost $1000. This vehicle is hazardous and an accident waiting to happen. There has been at least a few engine and electrical recalls. I don-??t understand why the car is passing the recalls, but exhibits the problems mentioned on recall. I feel like the dealership is waiting for my engine to fall out of warranty. Either the mechanic or machine isn-??t fully operational. I don-??t want to be on a freeway the next time my vehicle stops and have an 18 wheeler or other vehicle run into me.

I purchased my '16 Sonata as a Certified Pre-Owned vehicle. It was 1 yr old, with roughly 36k mi on the odo. I bought it from Huntington Beach Hyundai, who showed me the Car Fax that it's CPO. They promised Hundai CPOs get what left on the 10 yr, 100k mi powertrain warranty. I've been doing oil changes per manufacturer recommendations since purchase. At roughly 40k to 60k on the odo, I noticed the car was burning a lot of engine oil. I brought my car to my local Hyundai service center, Tustin Hyundai, who told me 1 qt every 1k mi is normal. I thought it was a lot, but Tustin Hyundai told me there was nothing wrong with the car. Sometime after, I received mail about the Theta 2 engine recall to get the knock sensor install/update, and read about the risk of engine explosion/fire. I promptly got it done. Around this time, I read on Hyundai owner forums that excessive oil consumption is a precursor symptom to catastrophic engine failure. Sometime later, I noticed my car was burning a lot of oil, even more than before. I estimated at least 2 qts every 1k mi. I brought my car to Tustin Hyundai at roughly 75k mi on the odo. They started an oil consumption test, comprised of 3 oil level readings, each one every 1k mi. My car failed the first two. After the 2nd, my car stayed at Tustin Hyundai overnight to get a combustion chamber clean done. Tustin Hyundai told me doing so will solve the problem. Few months later, I noticed my engine was back to even more excessive oil consumption. I estimated at least 3~4 qts per 1k mi. I brought my car to Tustin Hyundai again, with roughly 80k mi on the odo. They said Hyundai corporate is rejecting all further service because my car isn't CPO, and that I ran out of powertrain warranty at 5 yr/60k mi. I called Huntington Beach Hyundai, who confirmed my car is CPO, and still has the 10/100 powertrain warranty. But Hyundai corporate, through 2~3 national case managers, told me I am out of powertrain warranty, and not covered.

Purchased the 2016 Sonata approximately four months ago. Was not told that Hyundai had a problem with the engine in this year and model. I have now learned that NHTSA is involved in this matter because there have been several engine fires. My car is rapidly burning through motor oil. While it is not smoking there is a light smell of burning oil. Reluctantly the dealership is promising to fix it but has yet taken steps to do so. FOREMOST, IS IT SAFE TO CONTINUE DRIVING THIS CAR? Further, can the engine be repaired or should it be replaced. A prompt response would be greatly appreciated!

My car is involved in the class action lawsuit because of engine failure and fire with my 2016 Hyandia Sonota. I have concerns with the above issue because of knocking in the engine and using 1 quart of oil every 400 miles. Hyandia extended the Power train settlement for life time. Yet, they denied to do anything about my car because or 98,700 milage. Dealer said only way Hyandia will do anything if the engine goes out. Hope it just goes out instead of catching fire. Need help, if you settle take care of the customer. Should take care of the customer before settling.
