Aug 9, 2022 ~1pm. Driving ~60 mph south on highway 18, 30 miles north of Lusk, WY. Heard 30 seconds of slapping noise from engine, follow by oil pressure low light. Accelerator also ceased to function. Pulled to side of road and waited for tow. Towed to Ken Garff Hyundai in Cheyanne, WY. Inspected on Aug 25, 2022 by technician at Ken Garff two weeks after incident. Hyundai authorized engine replacement. Hyundai also stated twice that there was a recall on the car. No recall appears in the NHTSA database. Problem is very similar to Part 573 Safety Recall Report 21V-727, which includes the 2017 Hyundai Tucson.

The vehicle has 81,000 miles with regular oil changes. We purchased as a certified pre owned with 45,000 miles on the vehicle. The car had been running perfectly. Last weekend the car was making an awful noise. Today the mechanic tells us the lower unit is knocking and the motor will need replaced. There is no way this should be happening at this mileage especially since the car has been regularly serviced. Hyundai is not even interested in repairing the vehicle, went straight to trying to get me to trade it in. We could have been stranded or killed on the highway and with all of the other complaints about this motor, I can-??t believe there hasn-??t been a recall.

The contact owns a 2018 Hyundai Tucson. The contact stated while driving approximately 55 MPH, the vehicle lost motive power and decelerated. Additionally, the vehicle was making a ticking sound which became a loud knocking sound. Additionally, the engine was revving however, the vehicle was decelerating. The contact stated that there was no warning light illuminated. The contact pulled off the highway safely and then drove the vehicle to her residence. The contact's husband then drove the vehicle to an independent mechanic who diagnosed that water had entered the engine cylinders and determined that the engine needed to be replaced. The vehicle was not repaired. The contact was informed by the independent mechanic that the failure was related to NHTSA Campaign Number: 21V727000 (Engine). The manufacturer had been informed of the failure. The failure mileage was approximately 78,000.

I have a Hyundai 2018. I bought it in 2019 with about 64,000 miles on it. I keep up with all the maintenance on my SUV. I noticed once I moved from Illinois to Florida, after having the car for a year, it started consuming a lot of oil. I've never had an oil leak anywhere on the car. In November of 2020 I went to Take 5 to get my oil changed and the mechanic said make sure to check my oil often because my truck burns a lot of oil. I'm find myself putting oil in my truck once a week. Every 500 miles it needs oil. The crazy thing is, is that the oil light never once came on. The engine light will come on. I went to a recall appointment 2 weeks ago, which was the same day I got my oil changed June 11, 2022, and I told them about this issue and they did nothing. By June 23rd I needed more oil! I see California has a lawsuit about this issue. I want to trade in my truck because this is costing too much money feeding this truck gas and now oil!

Powertrain issue. Multiple times the after stopping the engine revs for a few seconds and then the vehicle will lurch forward. It acts like the CVT transmission has a delayed response to the accelerator. The condition comes and goes and sometimes it happens multiple times in the same trip.

my 2018 Hyundai Tucson starting having lurching issues on when first started. i have to back into my driveway so i dont have to go in reverse then go forward. it jerks back and forth so hard. It finally took its toll on the transfer case and it exploded internally. the Dealership said they had never seen this before. i was hoping that was the cause of the issue but it wasnt. Still doing it and am afraid it will do it again. i was under warranty when it happened, so teh $2000 replair was covered. i'm concerned it will happen again. teh problem goes away after it's been completely warmed up. but like many others, its a scary issue when first started. it also will also shift hard when it firsts get's going (after the initial hard lurching back and forth). i dont know what to do. Love the car otherwise, but concerned with ever buying a Hyundai again.

very bad acceleration from a stop position, engine revs but does not move, in slow traffic it hesitates and lunges forward like it-??s not sure what it-??s suppose to do, when trying to merge or pass another car, you have to give yourself time, it-??s very dangerous, took it to the dealer 2 times, was told that-??s how the car is made, there is no way this is suppose to be the way the car was built. also a smell of antifreeze but no leaks detected,

The contact owned a 2018 Hyundai Tucson. The contact stated that while driving up a hill at 30 MPH, she heard an abnormal popping noise emitting from underneath the vehicle without warning. Upon inspection of the vehicle, the contact saw that a fire had started from underneath the front passenger side of the vehicle. The vehicle in front of hers witnessed the fire and assisted with calling the authorities to the scene. Both the fire and the police department arrived as the fire department extinguished the fire. Both a police and fire report were filed; no injuries were reported. The contact had the vehicle towed to an independent tow yard where it was deemed a total loss. Upon investigation, the contact linked her failure to NHTSA Campaign Number: 20V543000(SERVICE BRAKES, HYDRAULIC); however, the cause of the fire had yet to be determined. Both the dealer and the manufacturer were notified of the failure. The vehicle had been destroyed. The failure mileage was unknown.

Catastrophic engine failure due to loss of oil pressure without warning at highway speeds. Traveling approximately 70mph on the freeway. Engine develops a rapid knock in sync with engine RPM's and immediate loss of power. At the same moment, I exited the freeway. As I left off the accelerator to apply the brake, the engine stalls completely. Once stopped, I checked the engine oil, which was within specifications. Had vehicle towed to a mechanic and diagnosed as engine failure due to loss of oil pressure. Before this, the engine regularly consumed 2-3 quarts of oil per oil change starting at approximately 45,000 miles. Catalytic convertor has been replaced once due to being plugged by consumed oil. Hyundai fails to remedy.

My engine has locked up on me and stalled because of water in the oil. I was never informed about this -??knock sensor-?? update for Hyundai that would have prevented all this in the first place. I-??ve had to come out of pocket for 2 tow trips and loaner car all while my vehicle is under 5 year/ or 60,000 mile warranty!! Now this apparent -??America-??s best warranty-?? local dealership is trying to tell me that my repairs are not covered under the warranty and I would have to pay $10,000 out of pocket for the repairs! This is going on 3 months now and still no one has contacted me and no one is helping me. That vehicle is my ONLY source of transportation to and from work an hour away! I am unsatisfied with my Hyundai Tucson and the false advertisement for claiming to be -??America-??s best warranty-?? and for not providing a safe reliable vehicle like Hyundai promises!

Rod bearing failure. Sounded like a tractor all of a sudden and stalled every time I-??d come to a stop. Had it towed to the dealership. Awaiting word from Hyundai as to whether the warranty will cover this. Checked oil and wasn-??t low. No check engine lights or oil lights or anything ever came on. No noises prior to this happening. Kept up on routine maintenance.

I bought my 2018 tuscon one year ago in June 2020. 70,000 miles on it now, regular maintenance. No warning lights, everything was running OK. I started experiencing hesitation taking off then lunging when stopped in the last few months. Now I'm sitting in the driveway because it won't start. Realized oil was low which is odd because I've noticed it's been burning more than previous but no more than a quart so it's not like it was dry. I'm supposed to be able to get 5k on an oil change now adays but starts running poorly if it's not changed by 3k. Needless to say iadded qt of oil I was going to get oil changed yesterday but wouldn't start. I changed the battery, still won't start, starter was tested good, fuses all in tack, changed camshaft sensors at 90 dollars a piece still nothing. Check alternator that's fine. It clicks one time but have all lights power everywhere it should. In 2 days I've spent 215 on a battery, 200 with tax on sensors, 50 code reader no code by the way. Did have p0014 which indicated need for either oil change or camshaft sensor. Nothing. I'm a sitting duck and all the things I've experience are what they experienced in the theta engines like hesitated, burning oil, ticking sounds, lunging etc. GDI isn't any better. I hate this car. After this one is paid off and I guess put a new engine in I'll be getting rid of it. Going back to a solid Buick. I'll never buy another hyundai. This is the second vehicle with engine problems we bought. Not to mention the risk of for but hyundai near me hasn't been able to get the parts for over a year. I'm currently in a wait list.
