UNKNOWN While driving, the check engine light came on and the car started idling rough. When accelerating the car would shake tremendously, feeling like it would die right there in the middle of the road. When I stopped at where I was going, I checked the oil and there was no oil in the engine. I added oil but it did not help the situation. I made an appointment with the dealership in Waco, Texas and when I showed up they stated they no longer had room for me and to make another appointment. They also stated I didn-??t have a warranty as I am not the original owner even though I purchased the extended warranty and I have not passed the mileage or date. This is unacceptable as I do not feel safe driving my car and they did not honor the appointment I made.

The contact's family friend owns a 2017 Hyundai Tucson. The contact stated that while the family friend was driving at an undisclosed speed, the engine made an abnormally loud knocking sound. The check engine warning light was illuminated. The vehicle was towed to the dealer, where it was diagnosed with connecting rod bearing wear and it was determined that the engine needed to be replaced. The dealer denied the engine replacement due to a lack of service records. The vehicle was then towed to Hyundai of 110 (2100 Broadhollow Rd, Farmingdale, NY 11735), where it was also diagnosed with connecting rod bearing wear and it was determined that the engine needed to be replaced. The vehicle was not repaired and remained at Hyundai of 110. The manufacturer was made aware of the failure and a case was opened. The contact related the failure to NHTSA Campaign Number: 21V727000 (Engine); however, the VIN was not included in the recall. The failure mileage was approximately 45,000.

I was driving at 10 mph speeding up and the engine went out. There was oil in the engine so it wasn-??t from lack of maintenance and I just bought the vehicle a month and a half prior to the incident.

Car has 125,000 mi on it. This will be the 3rd catalytic converter in 2 years. Second one was March of 2022. I have excessive oil consumption (1QT every other week). Which I believe causes the exhaust system to clog. It-??s an engine flaw design I believe. The issues isn-??t the converter but the oil consumption contributing to the clogging. The vehicle actually had complete engine failure while I was driving on the interstate Dec 23, 2023 driving at 70 miles an hour! It was caused by the clogged converter! I could have died! Thank you.

NHTSA Recall No. / MFR Recall No. : 21V-727 / 209 Recall Subject : Engine Damage May Cause Stall or Fire I am the second owner of this vehicle, purchased Jan 2021. I have not received any letter, calls, notifications from the Hyundai dealer where I purchased regarding any sort of recall for over the last 2 years. It was not until I went to get an oil change and I was told there was ZERO oil in my vehicle. The car will not hold oil, does not leak onto the ground, makes a knocking sound and not once has the oil light came on to alert me. This was my very first car purchase and to have a problem such as this is very frustrating. Not to mention that I have had zero notifications about this recall regarding this issue for my car. It was not until I decided to research on your site if there were recalls did I find there were not only one but 3, and this was one. I call the dealership, and they inform me that this is not a recall and I need to pay $175 for a diagnostic fee and this is an ongoing issue with these vehicles. Now I know I will probably receive an automated response in return and nothing will come of this. As of yesterday January 9/2024 my car had zero oil in the engine, has two codes, a solid check engine light on (still no oil light notification) and the mechanic indicated this was an internal issue and would not repair my vehicle. Someone please help.

Engine check light came on on 1/4/24 took it to dealership they ran a quick check and they said it had multiple misfires. The car has a lot of carbon buildup and they recommend a 24 hour cleaning which will cost me over $700. The car stalls and starts shaking as I speed up. I don't feel that a care with less than 70,000 miles should have this problem. Mine also has now been using up the oil very quickly.

The vehicle drove fine on Christmas Eve. Then Christmas Day while leaving from a visit the car was in then randomly shut off in the middle. Checked the inside. No issues. Made it home and tried to go back out, the car crunk up and after a few seconds cut off. Tried it again and it started knocking. Checked everything again. Tried to crank the car up after about 30 seconds the car got extremely loud and shut off again. A mechanic came to check the car and said it was the engine/motor. Then another mechanic at the shop mentioned that it appears to be similar to the issues in recall 209. Along with multiple other possibilities since Hyundai has been having issues with engines for years.

My engine began making a loud knocking sound. When I brought the car in, I was told the rod bearings were warped, that the sound I was hearing was a rod hitting the engine, and that the engine would need to be replaced immediately or it would "seize up" at any moment. No warning light came on. There is a recall out for this issue for the same make, model, and year, but I was told my VIN did not qualify under the recall. I opened a case with the national office to have my car included under the recall as it is the same issue with the same make, model, and year, and was denied. I had to spend several thousand dollars on a rental car and purchase a new vehicle. The issue with the Hyundai has still not been addressed or remedied. When I went back to the dealership for the paperwork for my records, I was told no paperwork was completed when they diagnosed the issue.

Chronic over consumption of oil. You could change the oil and a day later the oil is completely black and burnt. Roughly lost a.5-1quart of oil a week doing minimal commuting. Eventually the wear from oil consumption left us with a cylinder loss and in need of engine replacement. The vehicle only has 65k miles. Clearly this is a serious problem with these cars. There is an active recall for this problem but our VIN doesn-??t list. This is also the problem with many others who I have seen across all forums quora, Reddit, etc. We are sold Lemons and then footed with the cost to replace when this problem is very much known. It-??s wrong on every level.

I was driving the car home and the check engine light came on, the oil light came on and the battery light. The car shut off and I coasted off to the side of the road and proceeded to get the car towed home. I then called larson hyundai in olympia wa. The first service advisor I spoke with after I told her what happened told me the car had a recall that was open for the engine and to bring it in on Nov 15 The car sat for 2 months waiting for the appointment. I finally dropped the car off at the dealership on Nov. 15 and two weeks later I get a call from the service department saying that it won't be covered. This is completely unacceptable And the car needs to be fixed Also the service advisor who is currently working with the car is the rudest employee ever. Today 12/22 she called and informed they want 10,000 for the engine to be replaced I was shocked and paused for a second. All I hear is her saying in a snobby voice he hung up and she immediately hung up the phone. Please help me with this

I was driving down the road and my -??check engine-?? light came on and started blinking. Immediately afterwards, I noticed that my car acted like it would not accelerate. When I came to a stoplight, it was very sluggish to accelerate. I was right near an O-??Reilly-??s so I pulled in and had them use the code checker. It showed a P1326 code and I was advised not to drive the vehicle. I had my car towed to the dealership. The dealership called me the next day and advised me that the engine would need to be replaced, but the cost would be covered by an extended warranty. However-they told me it would be 2 months before I would get the car back!! They are not offering a loaner car nor offering to pay for a rental car! There is less than 65000 miles on my car! This is an extreme hardship on me. I work 25 miles away and cannot afford a rental vehicle for 2 months!

My engine began to leak and burned oil to a point where it needed oil changes much frequently than normal. Within 2 months of being made aware of the leak, I began to hear knocking noises. Once I return again to the dealership I was made aware now I needed a new engine. How is it that I've had my vehicle serviced only at a Hyundai Motor dealership and once my warranty is out, I now need an engine? What makes matters worse, there is a current recall on my vehicle year and make for the engine but I was told that my engine doesn't fall under this recall. I beg to differ! I am frustrated that I have yet another Hyundai that has failed me and I am stuck without a vehicle.

Appears to be an issue with the Dual Clutch Transmission. Makes the suv jolt after starting, waiting in traffic/red light and/or randomly driving around. Speed is not a determine factor in causing this -??jolt-??, for it happens at any rate of speed. Fear is the suv will randomly just stall and/or completely give out while driving, especially on the highway!

A knocking noise from the engine that increases in frequency as the engine rpm increases. Reduced power and/or hesitation and vibration. Illumination of the -??check engine-?? light in the instrument cluster. Illumination of the -??engine oil pressure-?? warning lamp.

Body - exterior. Door handles stop working and cannot open the doors. Engine - massive oil consumption issue. Having to put in roughly 10 QUARTS of oil in between oil changes, but low oil warning light inside of the cluster also never comes on to let you know if the oil is low.
