2016 HYUNDAI SONATA Engine Problems

The knock sensor detection system is messing up

On Thursday June 30th my 2016 Hyundai Sonata started jerking and stopped on me. The check engine light or any of the warning lights did not come on to warn me of any issues on any of the previous days. Since i was at Wal Mart I was able to get it pushed into the service center. The service techs there said that there was no oil in the car and only sludge came out. They changed the oil and I was able to get the car home. The car shook violently as I drove it but I was still able to get it home. Once I was home I lifted the hood to check the engine and noticed the engine covered in oil.I immediately called the dealership and they asked me to call Hyundai Consumer Affairs as oil consumption was a known issue with the Hyundai Sonata. The consumer...

My daughter’s car just shut off Tried to start the car several times and heard loud knocking noise with oil light flashing. Towed the car to local repair shop and was advised we needed a new engine. We’ve had the car for a year! This is my 2nd purchase of a Hyundai car for my daughter and I’ve realized THEY ARE A PIECE OF CRAP! With the 1st car, we had light replacement issues constantly as well as ac issues. Now we have engine issues. I wanted a safe economical car for my daughter and I’m ending up paying more money on this crap. I’m praying it’s covered under a recall.

Engine caught on fire while driving

The engine is consuming oil at abnormal rate. After receiving an oil change at a credible business the car is out of oil in a week. Hyundai will not check for oil consumption if the mileage is above 85k miles. Myself and my children can be stuck on the side of the road for engine failure due to the lack of oil. Express oil has stated this is not normal and a cause for concern. There are no warning signs for this problem. Only awareness from the performance of the cars decline to run properly.

When driving at 65+ mph the "Turn off Engine - Check Hybrid System" flashing triangle warning lamp came on, causing me to pull over on a freeway putting myself in danger of collision. After turning off vehicle with no explanation of warning symbol in owners manual I turned vehicle on again after 5 minutes and warning lamp re-illuminated. After waiting 30mins while still on shoulder of major freeway, I reignited engine and warning lamp had disappeared so I drove vehicle home (less than 5miles) and took to Hyundai service dealer the next day and they determined the coolant (water) pump and thermometer needed to be replaced and it was a known issue covered under 100k warranty. My vehicle was at approximately 102,700 miles and I paid for replacement of coolant pump and thermometer out of pocket.

The car still runs and drives fine but it is using almost a qt of oil a week. The dealer is Autonation Hyundai of North Richland Hills, Tx knows the history that these engines are junk. But rather than be stuck with this issue they told me my valve covers were leaking and that was my issue. Keep in mind I have no oil leaking from anywhere and not a drop is on my car or on the ground. This car has...

While driving on the highway in Michigan I noticed the engine RPM not functioning properly. The timing on the engine was off and the shifting was irregular. I pulled over to the side of the road with fear it was going to do more damage internally to the engine. If I had the cruise control on I was in fear of the engine malfunctioning and causing damage to other vehicles on the road. Upon further inspection I noticed the variable valve censor connector had an electrical shortage and burned a hole right through it. I was afraid of more electrical damage that could have turned into an engine fire. So I didn’t drive it anymore.

Hyundai Motor America is doing fraud with its customer’s and putting their lives at danger. They made engines with manufacturing defect. They sent a brochure to their customers to get the software updated for knocking sensors and then placed a lifetime warranty for the issues caused by it including any repair costs. They said the software will detect the knocking noise and will turn on Warning lights (Engine Light) as well as place the vehicle into reduced power, engine protection mode. Their brochure said they have defective engines in 2011-2019 Sonatas, 2013-2018 Santa FE Sports, 2019 Senta Fes, and 2014,2015, 2018 and 2019 Tucsons.I own a 2016 Hyundai Sonata. I did software update and then I started having engine knocking at around 76,000 miles. Sometimes, car automatically loses power on highways/freeways and sometimes it starts to accelerate on its own at very high RPM’s. I contacted Hyundai dealership in Spring,...

My oil seems to be consumed really quickly! I get a full synthetic oil change and then my engine sounds strange and check the oil and there's no more oil in there! This is after less than 1,000 miles after the oil change! It's very expensive that every few months I need to go and get a new oil change, it's supposed to be every 6 months or after 5,000-7,500 miles with full synthetic but it only last about 700 miles before it starts to start to disappear! I'm scared it will cause my engine to get ruined and make a fire! This has been going on formore than 2 years now.

Yesterday, my car’s engine/battery/oil lights came on. I pulled over, checked the oil and it was almost completely dry. I went to start the car again and it would not start. After my mechanic checked the starter and battery, they determined that the engine was locked up. My engine could have caught on fire as there was no warning prior.

Took car to accredited service center for routine oil change early. Was given an opinion that the their was internal engine damage and that my engine would blow out if car was continued to be driven. I then had it towed to Hyundai dealership to be serviced and to get a second opinion. Service was done, and told it was a simple issue, after paying $400 after services were complete, I left feeling relieved it wasn’t a bigger issue. Not less than maybe 6 hours later, early sunday morning, I was driving at night on the road and my engine completely blew out on me. My safety was put at risk and others around me on the road as well because I could have caused an accident, if I had been on the high-way going a higher MPH, my engine would have more than likely caught on fire or possibly...

Engine is consuming a quart of oil every 400 miles.

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

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...

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.

He has been saying there is an issue with engine buring oil for some time and recommended contacting this agency and dealer.

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,...

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...

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.

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 .
