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.

I purchased my car used in December 2021 it is a 2016 with 97k miles. 2 weeks after I purchased the car I called to set up service because my cars engine was making horrible sounds. with me putting less than 900 miles on the car (it took 2 weeks to get it in for service) I had a in near perfect condition car with a blown engine. 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 an oil consumption problem along with thousands of other Hyundais and neither Autonation or Hyundai are willing to do anything about it because I am the second owner even though I bought the car in this condition from the dealer. The engine is failing because it is consuming oil. The engine is making noises and could at any time while driving could lock up and cause a dangerous situation on the roadways. This is a very well known issue and even a current class action lawsuit. The dealer is refusing to inspect the vehicle because I am the second owner and have no warranty. The only sign is low oil. The car is using oil at a rapid pace and I have to check and add oil weekly. This is a 5 year old car with 100k mikes on it.

Complete engine failure engine failed in 2021, prior to recall notices (2 of them) finally had it towed to hundai. Hundai wants me to buy a new engine block for $13,000 thirteen thousand dollars. Hundai needs to buy that car back, or pay to put a new engine block in it. Had the parts not been faulty, I'd still have a car to drive.

The engine is still under the orgininal warranty (10 years, 100,000 miles). I took my car to Parks of Hyundai in Gainesville, FL on 09/23/2021 for an issue with engine code p1326. The service manager reset my engine code and told me that their service department is backed up with cars and they cannot help me with my car at this time. Then on April 5, 2022, the issue happened again to my Hyundai Sonata on the interstate, the car engine went into limbo mode in the middle of the interstate and almost caused a large accident. I have the engine code p1326 showing up on their computer I took my car back to Parks of Hyundai on April 5th, 2022. Parks of Hyundai told me that I had to leave my car with them and that they refuse to provide me with a rental. Karl Buchwald, stated that it will take a few days to get to my car, and they will let me know what is wrong with it plus diagonistic fee of $200 even though I provided him with the engine code number thats under the powertrain warranty on the car. I went home and called Corporate Hyundai and opened a case. Case no: 19623500 case manager Emily, number 1(833)462-8722. Corporate Hyundai says I have to pay out of pocket for my rental and then submit my paper work after for possible rental reimbursement. I went back to Parks of Hyundai to check on the status of my car on April 13, 2022, Karl Buchwald, states that it may take 2-3 weeks for them to take a look at my car. When I asked to see what was done on my car, he told service advisor Michelle to enter my car into the system. My car was at their dealership for a week without paperwork. Eric Duke states that since I did not purchase my car at their dealership, the wait time will be longer. I waited 2 weeks and went back to Parks of Hyundai to check on my car yesterday 4/27/2022. Nothing has been done, they said it will be a few more weeks for diagonistic.

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.

Started oil consumption testing in Aug 2021 through Hyundai due to the vehicle taking in at least 1.5 qts of oil every 1,000 miles. After multiple tests, Hyundai completed a combustion cleaning in Jan 2022. No changes. After an additional oil consumption test in March 2022, Hyundai has advised this is normal consumption. No action to be taken from dealer/Corp until engine blows a rod. Manufacturer &/or dealer prefers for my family to suffer a dangerous and potentially catastrophic event before addressing what is to be a known issue with this year/make/model.

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, TX (North Freeway Hyundai), which told me that Hyundai doesn-??t cover it anymore until unless its complete engine failure. This is not what their Warranty document (Brochure) said. They are denying to take care of the issue which was caused by manufacturing defect and their software update. Their brochure said they will take care of it including any engine repair costs. Their dealership told me that this is just the -??Beginning of the engine falling apart-??, they can start with putting a new cover on the faulty engine part rather than replacing it, which will cost me $640.50+tax to take the engine light disappear for few days. If they have to fix it permanently, it is going to cost me -??Thousands of Dollars-?? into parts and labor charges. Private mechanic said Hyundai Engines are "Can of Worms" and wont even touch it. As per Hyundai case managers instructions, I ended up spending $435.50 out of pocket without any work done on my vehicle. As per their Brochure, they are making defected engines from 2011. Thousands of people driving those dangerous vehicles.

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.

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 have caused an accident. Clearly the issue was not fixed and they sent me to drive in a car that was faulty and not fixed, endangering my life and possibly others around me. It has only been inspected by hyundai, but clearly inspection by them is inadequate. No engine light warnings ever appeared. Oil light would occasionally flash on and off but I didn-??t think anything of it because, 1) no loud sounds/vibrations were happening, 2) my next oil change service wasn-??t until almost over 1,000 miles, as I regularly keep up with maintenance on my vehicle. I would say the on and off oil light was flashing maybe for about a week or so, and this was NOT after prior oil change, this occurred miles and miles after. I have attach pictures from the 1st opinion service, as well as the service I received from Hyundai before incident occured. I have also if needed to be provided, documentation of routine maintenance by Hyundai Dealership and from an accredited service center by the Better Business of Bureau.
