I was merging onto a highway at high speeds when the car stuttered. The check engine light began to flash and I lost acceleration. I could push the gas pedal to the floor and the car would not accelerate at all. The car lost it's speed and I could not go anymore than 30mph, and it would not go higher than 2rpms. It put me and my baby (who was in the backseat) in danger as we were going fast on a highway and out of nowhere the car lost speed and I could not accelerate. I could've easily been hit by another driver going the regular speed limit. I drove it to the dealership that just happened to be down the street, and the car struggled to accelerate from a complete stop, as well as in general. From a complete stop, the car would sputter and jerk when pressing on the gas pedal. The dealership diagnosed it as a faulty Knock Sensor. They said they would replace the sensor as it was still under warrenty. When I left the dealership, the check engine light was off and the car was driving fine. Fast forward to the next day, I was driving again on a highway at about 65mph, when the SAME thing happens. The car stuttered, lost all acceleration, and the check engine light was flashing. I ended up driving it home (about 10 miles away) and the whole time I could not go faster than 30mph without the car shaking. This time the car would not go higher than 1.5rpms. I checked the engine at home and a P1326 code came up, which is a code for the Knock Sensor. I called the Hyundai dealership that I originally went to and they said there was nothing they can do about it at the moment since they had just replaced it. Prior to all of this, there was no warning sign at all that this was a potential hazard. It happened so suddenly and both times it happened put me in a dangerous situation.
The contact owns a 2019 Hyundai Tucson. The contact stated while driving approximately 45 MPH and merging onto the highway, the vehicle began to lose motive power. The contact stated that the check engine warning light started flashing. The contact stated that a loud humming noise was coming from the engine compartment. Additionally, the steering wheel began to vibrate. The contact pulled off the highway, and at the bottom of the off ramp she had to stop for a traffic light. The contact stated that when the light changed, and she depressed the accelerator pedal, the vehicle lunged forward while shifting from 1st gear into 2nd gear and then stalled. The contact stated that it took several attempts to restart the vehicle. The contact drove to her residence while the vehicle struggled but was unable to exceed 25 MPH. The contact drove the vehicle to an auto parts store and had a diagnostic test performed. The contact was advised that she had a code P1326 and other failures of the powertrain system. The contact called a dealer and was informed that the vehicle would not be diagnosed or repaired the vehicle was diagnosed by their mechanic. The vehicle was diagnosed a second time and the mechanic retrieved DTC: P1326. The vehicle had not been repaired. The contact researched online and related the failure to the federal safety agency Campaign Number: 21V727000 (Engine) however, the VIN was not included. The manufacturer had not been informed of the failure. The failure mileage was 81,859.
While driving, I came to a stop sign and the car completely shut off. The car restarted and then I stopped at a stop sign and the car completely shut off. I had the car towed and they told me that it had catastrophic engine failure. I haven’t even owned this car for 1 year yet. How could the engine fail. Upon further investigation, it appears that this is a known issue with Hyundai Tucson’s of the same year.
The contact owns a 2019 Hyundai Tucson. The contact stated while in her daughter's possession, the engine had failed to start after multiple attempts. Several warning lights illuminated the instrument panel during the failure. The vehicle was jumpstarted and the horn began to blare once the engine restarted. The vehicle was taken to a dealer where they were unable to determine the failure. The contact also stated that the vehicle would rattle while both idle and upon activation of the AC. The manufacturer was notified of the failure and the contact was given to a case manager; she was later instructed by the case manager to take the vehicle back to the dealer for assistance. The vehicle had yet to be repaired. The failure mileage was approximately 23,000.
In this 2019 Hyundai Tucson with about 31,000 miles, engine stalling occurred the second time during driving with two passengers on I-76 at approximately 73 mph in the cruise mode on September 11, 2022; the speed kept dropping and gas pedal did not respond at all; fortunately, the driver could manage to pull over the car to an emergency zone; from the lesson in the first engine stalling incident on I-376 on in October 2021, turning the ignition key to the OFF position then to the "ON" appeared to make the engine work again, like nothing occurred; there was no engine warning light, or OBDII warnings.
The contact owns a 2019 Hyundai Tucson. The contact stated while driving 35-45 MPH, the vehicle started jerking. The accelerator pedal was depressed but the vehicle failed to respond and stalled.

2019 Hyundai Tucson I purchased 13 months ago with a mere 5, 241 miles on it., (Currently 29k mi) from Bert Ogden Subaru/Mazda in Edinburg, TX. On 6/26/22 it Started Shaking violently then "rodknocking" and finally failing in middle of major, high-traffic hwy. Near causing accident. NOwarning lights, check engine lights, oil lights, etc. Car was towed to Tipton Ford Hyundai, in Brownsville, TX. As it urns out (through my own research), my vin# falls under a recall issue that was not fixed prior to purchase nor disclosed to me, re:"engine monitoring and logics warning system failure". More importantly, 2) There are several class-action lawsuits underway, one settled, in which Hyundai was found liable for faulty "class II Theta Engines" and a suit involving "GDI NU 2.OL" (same as my vehicle) leading to rod knocking sensor failure, premature worn bearings and even cars catching fire! This is a no-brainer situation in which hyundai should be replacing my engine as ordered, but instead they are claiming, vehicle "neglect" (all maint. receipts were provided)and rejecting claim(which seems to be their m.o. based on similar complaints / civil filings that are ALL OVER THE WEB) and dealer says Im responsible for paying for new engine. Not sure who is responsible: the dealer I purchased from, for selling me a defective vehicle, the Hyundai dealer it was towed to, or Hyundai itself for denying what is a VERY well known liability on their part and apparently a widespread years-long issues with engine defects, recalls, suits, judgements, etx but have many court transcripts of consumers claiming Hyundai blaming thd customer for "neglect" to avoid replacing engine. I need legal help and advice. I HAVE to have car for work and dealer knows it and seems hyundai does, because they wont cover rental, wont provide "loaner" and seems dealer didnt even debate this with HMA because I purchased vehicle elsewhere. They just accepted Hyundai's denial and is now attempting to take advantage.
Engine failure due to connecting rods issue. Engine began to smoke while driving with no warning, had complete engine failure and had to have vehicle towed to dealership.
The contact owned a 2019 Hyundai Tucson. The contact stated while driving approximately 55 MPH the vehicle started smoking and overheating. The contact was able to pull over safely. There were no warning lights on the instrument panel. Once the vehicle stopped the doors were automatically locked. The nearby drivers notified the contact of the fire under the vehicle. Once the contact exited the vehicle, the engine was destroyed by the fire. The inside of the vehicle was still functional. The state police arrived on the scene; however, a police report has not been obtained. The fire department also arrived and extinguished the fire. The vehicle was towed to a wrecking yard. The manufacturer was not notified of the failure. There were no injuries or medical reports. The approximate failure mileage was 40,000.
I helped my daughter buy a used 2019 Hyundai Tuscon with 42K miles since she was going to med school and needed reliable transportation. At 62K miles the engine failed. The engine stalled in the middle of the highway and she was in the middle of the highway for some time before she could restart the engine. She was nearly rear ended. The dealer she brought the car back to said there was no oil in the engine despite the fact that she had the oil changed two months before this incident. There have been many problems with the Hyundai "Theta II" and 2 liter GDI engines that were supposedly fixed and there was a class action lawsuit on Hyundai Tuscons up to 2016 which was well publicized. This car has a 2 liter engine (which is all I know). It does not appear that Hyundai has fixed their engine problems since I believe this is the same problem as before. I am filing this complaint in my daughetrs behalf since she has to take her medical boards in one month. It is bad enough that her car has been tied up for 3 months and she has to transport her husband across town twice a day.
As previously stated, was driving when csr began to smoke and stall. After almost three months of being at the dealership it was determined to be the ROD BEARING failure. Earlier models of this vehicle have been recalled due to this issue. Please look into the newer models as well.
Motor blew with regular maintenance done at 77k
When driving car slowed down and battery sign appeared on the dash board. The car started to gives jerks when stopped at the traffic light. When continued after the lights, it struggled to pick up. This happened two to three times in two days.
Engine stalled. Drove it to gas station but engine has knocking sound. Was told that it may fall under the Theta Engines recall.
Car started knocking on a Wednesday like it wanted to cut off, no engine lights came on. Got car towed to dealership on Thursday morning, still no engine light. Dealership called on Thursday said I need a new engine. Car was a 2019 Hyundai Tucson which I purchased in 2020 with 60,059miles. I was the second owner.
On 2-23-2022 , I was driving approximately 30 MPH when all of a sudden there was a noise that kept getting louder which sounded like a knocking or broken fan, the vehicle RPM increased, the vehicle hesitated, did not accelerate, stalled, the check oil and engine light came on, I coasted into parking lot. When I opened the hood, there was no signs of smoke, oil leak, or smells, however, when I went to check the oil, smoke came out of where the oil dip stick goes. I attempted to have the vehicle jump started with no luck, just a clicking sound. I had the vehicle towed to be serviced.
Was driving uphill, heard a clanging sound. Car engine completely shut off and started smoking, lights worked. Towed it to dealer, they said it will be 30 days before we hear about the issue, they said they will fix the original recall after tearing the engine down.
While driving down a busy road at 10:00 pm on New Years Eve, my vehicle's engine completely shut off. Immediately prior to the shut off, the vehicle's dash displayed the oil and battery lights. The vehicle's automatic emergency brake and steering wheel lock were both engaged, not allowing me (or the tow truck company) to move my vehicle out of this busy road. My car remained in this location for 3 and a half hours. The hazard lights stopped working after the first hour, making it extremely difficult to see that the vehicle was stopped. After the second hour, an officer parked behind my vehicle with their lights flashing as he said it was an extremely dangerous situation and my car was sure to be hit. He was able to get a tow truck to me before Hyundai. For hours, numerous people were forced to brake quickly/swerve into other lane to avoid hitting my car. This occurred right before an intersection, putting 4 directions of drivers at risk of collision. I stood in the rain, near my car, attempting to help direct drivers away from the lane until the police officer showed up. The vehicle is now at the dealership which confirmed engine failure, pending replacement. Possibly related, this vehicle had the catalytic convertor replaced 3 months prior. It is not yet confirmed if this contributed to the engine failure.
The engine in my 2019 Hyundai Tucson turned off while driving down the interstate without any lights or warnings. My 2 year old was in the back seat at the time, and this could have caused a significant risk to not only myself and son, but others on the road if we were not traveling at highway speed. The vehicle was safely pulled over to the side of the road and would not restart. I got it towed to the dealership it was purchased from and they informed me they have been having a lot of issues with engines recently and mine would need to be replaced. It has now been sitting at the dealership since Thanksgiving waiting to be serviced, which is covered under manufacture warranty. It is located at Hyundai of Brunswick in Brunswick, Ga and can be accessed if needed.
Purchased the vehicle in June 2021 only had 1 previous owner. The dealership stated it was a pre-owned certified used vehicle that had just been inspected and service. Within the first month I had to take it back for multiple issues most recently the catalytic converter to be replaced and the Engine. I haven't even owned it let alone driven it long or far enough for either of these parts to need service or have failed. It's not even time for my first oil change that how low the mileage is that I've put on it. The dealership originally told me they never head about the complaints regarding the engine now they are trying to stiff me on selling me a lemon by charging me 3000 and telling me Hyundai isn't willing to cover the repairs. If this is a known issue which is seems to be a recall should now be issued.
The contact owns a 2019 Hyundai Tucson. The contact stated that while her husband was driving at an undisclosed speed, several unknown warning lights illuminated. The vehicle was taken to an independent mechanic and diagnosed with engine failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 86,000.
Purchased the car in March 2021 with 41,391 miles on it. The day after I picked it up check engine light came on checked the code it was a P0420 catalyst system efficiency below threshold, contacted dealer they took the car in and replaced the catalytic converter. Now 8 months later & a little less than 15,000 miles the check engine light came on again and guess what code popped up? P0420 now I am not an auto expert but I don't think its right that a catalytic converter would need to be replaced twice in that short time frame. Time to figure out what is causing this considering I am not the only one who has reported this

2019 Tucson 74165 miles. While driving on the highway the engine began to knock, and as the traffic came to a stop the car stalled and the oil and battery light came on. Before that the lights never came on. I got it to the shoulder and checked the oil, it was dry with no leaks on the outside of the engine. Towed to my mechanic and he said total engine failure. Hyundai discontinued this motor and Jasper a leading engine manufacturer will not produce after market because they cannot warranty it for three years or hundred thousand miles. This will become a recall as this model year gets higher milage, and Hyundai knows it.
