While taking my children to school my check engine light came on and then a knocking sound started from the engine bay and a hesitation almost to the point of a stall began to happen. I have spoken to a couple of mechanics and they said the engine will need to be replaced. We do not have a Hyundai dealer less than 1 hour away so I have spoken to other certified mechanics first before having the vehicle towed due to the cost of towing. This is an exact match to the issue reported in NHTSA Campaign Number 21V72700 but Hyundai does not have the VIN for my vehicle listed in the recall campaign. The vehicle has 93,000 miles on it and they will not honor the 10 year/100,000 mile warranty due to me being the second owner and no recall issued for my VIN so I am out of a vehicle and no way to get it repaired.

I had sudden knocking in the engine soon after oil change was done very early (way before it was due)×2 due to the light coming on and I smelled burning oil and the check engine light came on the 2nd time i explained this to the dealership they didnt think it was urgent so they made me an appointment for 2 weeks out so i didnt drive my vehicle those 2 weeks the appointment came i had the vehicle towed there and i now have been without a vehicle 3 weeks so 5 total the warranty company has to send an adjuster (still hasn't come) and there aren't any loaner vehicles for me to use! I now cannot work 1 of my jobs bc it is impossible without a car ! Meanwhile ubering and rentals to and from the other job and school has depleted my savings account !

On 05/12/2022, my vehicle experienced sudden engine knocking and loss of power while driving. The check engine light turned on, so I took it to a repair shop. They informed me that the error code reflected a service bullet of TSB 20-01-024H-1 - Engine Inspection / Replacement. Upon research, I found out their is a recall for which I was never informed about. The vehicle will be taken to the Hyundai dealership for further review.

There are 3 recalls associated with this VIN...unsure why you are not seeing them on your end. We got a notice in the mail last week for Hyundai Recall Number 209 NU Engine. We contacted the dealership where we purchased the car and they couldn't get us in until June 17th. On Friday, May 13th while driving down 90 interstate the car's engine died and the automobile had to be towed to the dealership. Due to worker shortages the dealer is saying it could take up to a year to fix and did not offer alternative transportation. We are now in the process of securing a rental and trying to find another automobile while still having car payments on this one that was entirely due to a manufacturer issue. We want full reimbursement of all costs associated with this hardship. (RECALL RELATED INCIDENT)

An update on my previous complaint is attached. My vehicle has now been with the Hyundai dealership for two weeks with no resolution. They've provided little to no communication about the issues, or progress. Additionally, they have not provided me with a loaner vehicle, so I am without a mode of transportation for two weeks.

I purchased my 2017 Tucson in 2020. It was the first car I-??ve ever owned. I do not know much about cars but I noticed that there was some hesitation in acceleration and the engine was loud. Sometimes I would hear soft knocking on colder days but nothing extreme. I was told that the acceleration hesitation and the loud engine are due to the turbo. Then on 4/27/2022, without any warning, my engine stalled while I was at a traffic light. More importantly, I had ZERO warning lamps or messages. No engine warning or oil light was illuminated. My engine suddenly stalled. I don't drive my car very far. Use is relatively light. On average I drive about 10-20 miles per day. No one was hurt but what if this had happened on the highway? I would have definitely been rear-ended and hurt. My car passed inspection on 09/10/21. But earlier this year, on 22nd February 2022, I took it to the dealer for the engine recall (NHTSA Campaign Number: 21V727000). They assessed it and said it passed the tests but I have no way of knowing because the dealer would not share the full report. Additionally, the dealer did not address that the vehicle warning lamps and messages were not working when they noticed my oil was low. Hyundai has a long history of engine issues and recalls with regards to high oil consumption and connecting rod bearings inside the engine may wear prematurely. There are hundreds of complaints that match my description. Their engines have had issues since 2020 and these complaints date back to 2020 around the time I bought this vehicle. Even though there were no recalls at the time, the dealer should have disclosed these issues. I think it's negligence by Hyundai and the dealer for investigating why my warning lamps did not illuminate and did not properly communicate the seriousness of these issues.

While driving on the highway the vehicle would not increase speed after making a complete stop at a traffic light when pressing the gas pedal. While trying to back into a parking spot the vehicle would not go in reverse after shifting the vehicle into reverse and lastly the vehicle would not budge/move in neutral or any other gear. No warning lights came on. The dealership Hyundai of South Brunswick, NJ confirmed the vehicle locked up when the tow truck driver was trying to get it off the flatbed and that the transmission is shot and needs to be replaced.

Went in for recalls in feb, not even 2 weeks later car was put into limp mode check engine light flashing. Car was towed to dealership where car was purchased where they said it was due to metal shavings in engine. Car was delivered to Hyundai where they diagnosed it with a faulty knock sensor which had just been replaced not even 2 weeks prior. After getting it towed to another Hyundai dealer for a second opinion was told that bolts from the recall work were cross threaded and broken off into motor causing the metal shavings. Really unclear as to what happened but Hyundai refuses to replace engine warranty was denied. Unsure if Hyundai is aware of the failed engine due to recalls

My 2017 Hyundai Tucson refuses to accelerate after a complete stop at a traffic light, or just refuses to change gears after making a turn, or simply just lose power although on cruise control while drive on the freeway. I have reported the issue several times to Hyundai and the dealership, it seems that nothing can't be done and Hyundai is not taking my concerns seriously. I am not afraid to drive the car since I have a long commute to work, I escape several accidents before because the other drivers were cautious and kind enough when they notice that my car couldn't accelerate. Drivers have blown the horn at me on the highway because the car refuses to accelerate or change gear while I am driving. I can press the gas pedal all the way down, still nothing. When I press the gas pedal down, the engine start shaking and making a weird noise while the car still not accelerating or changing gears. I also notice that I am burning more fuel than expected, and I always get below the average for typical MPG. I personally consider this car is unsafe to drive, and I am strongly thinking about trade it in.

My 2017 Hyundai Tucson Has a recall (Campaign 209 ) The problem is a worn connecting rod bearing in the motor could puncture the engine block and cause a fire. So I took my car to my Dealer on Feb.4, 2022 All the Technician did was replaced a sensor never replaced the bearing that cause the problem. Invoice # 615008/1 On March 24, 2022 I checked Hyundai recall's I put my vin # in and it said NOTE with a GREEN check mark there are NO open safety or service campaign for this vehicle. IT looks like they took us out of the system so Hyundai Motor Co don't have to replace the BAD PARTS.
